We've now fixed IS_ENABLED() and friends to not require any special "__enabled_" prefixed versions of the normal Kconfig options, so delete the last traces of them being generated. Signed-off-by:

This reverts commit 953742c8 . Dumping two lines into autoconf.h for all existing Kconfig options results in a giant file (~16k lines) we have to process each time we compile something. We've weaned IS_ENABLED() and similar off of requiring the __enabled_ definitions so now we can revert the change which caused all the extra lines. Signed-off-by:

Linus Torvalds <torvalds@linux-foundation.org>
Using IS_ENABLED() within C (vs. within CPP #if statements) in its current form requires us to actually define every possible bool/tristate Kconfig option twice (__enabled_* and __enabled_*_MODULE variants). This results in a huge autoconf.h file, on the order of 16k lines for a x86_64 defconfig. Fixing IS_ENABLED to be able to work on the smaller subset of just things that we really have defined is step one to fixing this. Which means it has to not choke when fed non-enabled options, such as: include/linux/netdevice.h:964:1: warning: "__enabled_CONFIG_FCOE_MODULE" is not defined [-Wundef] The original prototype of how to implement a C and preprocessor compatible way of doing this came from the Google+ user "comex ." in response to Linus' crowdsourcing challenge for a possible improvement on his earlier C specific solution: #define config_enabled(x) (__stringify(x)[0] == '1') In this implementation, I've chosen variable names that hopefully make how it works more understandable.

sizeof(void*) returns an unsigned long, but it was being used as a width parameter to a "%-*s" format string which requires an int. On 64 bit platforms this causes a type mismatch: linux/kernel/irq/irqdomain.c:575: warning: field width should have type 'int', but argument 6 has type 'long unsigned int' This change casts the size to an int so printf gets the right data type.

If, in __persistent_ram_init(), the call to persistent_ram_buffer_init() fails or the call to persistent_ram_init_ecc() fails then we fail to free the memory we allocated to 'prz' with kzalloc() - thus leaking it. To prevent the leaks I consolidated all error exits from the function at a 'err:' label at the end and made all error cases jump to that label where we can then make sure we always free 'prz'. This is safe since all the situations where the code bails out happen before 'prz' has been stored anywhere and although we'll do a redundant kfree(NULL) call in the case of kzalloc() itself failing that's OK since kfree() deals gracefully with NULL pointers and I felt it was more important to keep all error exits at a single location than to avoid that one harmless/redundant kfree() on a error path.

If copy_to_user() fails in the WLAN_CMD_GET_NODE_LIST case of the switch in drivers/staging/vt6656/ioctl.c::private_ioctl() we'll leak the memory allocated to 'pNodeList'. Fix that by kfree'ing the memory in the failure case. Also remove a pointless cast (to type 'PSNodeList') of a kmalloc() return value - kmalloc() returns a void pointer that is implicitly converted, so there is no need for an explicit cast.

Pull networking fixes from David Miller: 1) Fix bluetooth userland regression reported by Keith Packard, from Gustavo Padovan. 2) Revert ath9k PS idle change, from Sujith Manoharan. 3) Correct default TCP memory limits (again), from Eric Dumazet. 4) Fix tcp_rcv_rtt_update() accidental use of unscaled RTT, from Neal Cardwell. 5) We made a facility for layers like wireless to say how much tailroom they need in the SKB for link layer stuff such as wireless encryption etc., but TCP works hard to fill every SKB out to the end defeating this specification.

Commit 6e6f0a1f ("panic: don't print redundant backtraces on oops") causes a regression where no stack trace will be printed at all for the case where kernel code calls panic() directly while not processing an oops, and of course there are 100's of instances of this type of call. The original commit executed the check (!oops_in_progress), but this will always be false because just before the dump_stack() there is a call to bust_spinlocks(1), which does the following: void __attribute__((weak)) bust_spinlocks(int yes) { if (yes) { ++oops_in_progress; The proper way to resolve the problem that original commit tried to solve is to avoid printing a stack dump from panic() when the either of() Signed-off-by:

RTC stores time and date in several registers. Due to the fact that these registers can't be read instantaneously, there is a chance that reading from counting registers gives an error of one minute, one hour, one day, etc. To address this issue, the RTC has hardware support to copy the RTC counting registers to static shadowed registers. The current implementation does not use this feature, and in a stress test, we can reproduce this error at a rate of around two times per 300000 readings. Fix the implementation to ensure that the right snapshot of time is captured. Signed-off-by:

SummaryThis article assumes a working knowledge of ADO.NET, and examines it and its influence on the middle tier. It introduces a fictitious business model and lists some requirements to help us focus on the middle tier. It also introduces a new mechanism called SQLData, which combines both the ADO.NET DataSet and the ADO.NET DataReader into a single mechanism. The SQLData struct is used as the basis for developing a middle tier. Finally, the performance of the SQLData struct is measured and contrasted with a wizard-generated strongly typed DataSet. Many .NET items such as interfaces, enumerators, and delegates are used.
The Middle tierIn a traditional three-tiered approach to software development the middle tier, or business object layer as it is sometimes referred to, is the layer of architecture that models and enforces the business rules and/or data of an organization. A properly designed middle tier should express itself in a highly readable form, be robust, be resilient to change, and be distinct from the user interface. Generally, component-based architectures that can express the business rules and processes, as well as scale to meet demand, work well for creating middle-tier architecture. Enter .NET.You may be asking, Why, of all the new technologies and features in the Microsoft .NET Framework, should I focus on the middle tier? Hasnt enough attention already been paid to this area? There are two main reasons this article focuses on the middle tier. First, the introduction of the Microsoft .NET Framework and its comprehensive class library will attract many newcomers, converts, and old-time Microsoft C++ ATL COM guys like myself. At first glance, the .NET Framework can be overwhelming -- not with its complexity, but with the breadth of infrastructure only a .NET namespace away. The point here is that although technology is always changing, good software development practices span technologies. This article looks at the .NET Framework from the middle-tier point of view because thats where many of us labor. Also, many developers who previously worked only in ASP script are going to find themselves either working on or writing the middle tier, because the ASP.NET programming model uses the same first class language(s) that the middle tier uses. ASP.NET developers will be writing .NET components -- and this is good for the industry, as more people will be available to work on core infrastructure. Many developers, new and old and with varying experience and backgrounds, will find themselves challenged by the task of writing a coherent middle tier -- whether they know that's what theyre writing or not. Some mentoring will have to take place, and I hope this article will help some get a foothold in the .NET Framework.Second, I have seen the introduction of XML cause confusion, especially with respect to its relationship to the middle tier. Some developers are even drifting, knowingly or unknowingly, back to what I call the monolithic application. Why write a middle-tier component when SQL Server 2000 can retrieve our data in native XML? We could then transform the data into HTML through XSL/XSLT and go directly to the browser. Why create a middle-tier component with all of its methods and properties? The answer to this question is an article in itself. Suffice it to say that you have to be able to receive the data back from the browser. Do you receive the modified XML and simply stuff it directly into the database? If there are no business rules associated with the data thats a possibility; this is not very likely, however, even for the smallest application. There is nothing preventing a middle-tier component from offering itself up as XML data; the trick is to know how to handle the modified XML data when its received, and to invoke the proper business logic.My caution to the reader: Be careful if you are currently weighing the decision to develop a new project without a well-defined middle tier. This is not to say that it cannot be done successfully, but there is considerable risk involved in attempting to do so.Our Data Model and RequirementsThe example we are going to use throughout this article will be a very simple human resources middle-tier model. We will need four business objects: an Employees collection, an Employee object, a Dependents collection, and a Dependent object. An Employee can have zero to many Dependents. Let's look at our hierarchical model.
Figure 1 The Hierarchical Data Model
Our requirements are as follows. We want both our Employees and Dependents collections to be able to hold instances of our individual business objects. At the same time, we want to be able to create and work with our individual business objects outside of our collections in cases where we desire only one record of data. When working with read-only data, we want to use the ADO.NET DataReader class for performance reasons, and the ADO.NET DataSet class when we desire writeable data. We want to use these two different data access mechanisms without affecting the readability of our code. Finally, we want to avoid calling the new operator as much as possible and thereby reduce our garbage collection and object creations cycles (as you will see, these things still matter). Our collection classes must only allow access to the objects via the foreach syntax.
Where to Start?The middle tier often has a lot to do with exposing a well-designed data model to the presentation layer. Consuming ADO.NET then becomes the first order of business for the middle-tier developer. The differences between ADO and ADO.NET are significant, and will probably be one of the most confusing issues in transitioning to the .NET Framework. An early start is a good idea.
If you are familiar with ADO (the COM-based data access strategy), then you are familiar with the Recordset component. A Recordset can operate in either a disconnected or a connected fashion, and it is capable of serving up data in XML. ADO Recordsets can also operate in server-side mode -- a capability ADO.NET currently does not support. This is not usually a concern, as keeping connections open in web-based applications is usually unadvisable.
Unlike ADO, ADO.NET does not offer a single component that operates in both a connected and a disconnected mode. Instead, there are two layers, the DataSet for working with data in a disconnected and updateable fashion and the DataReader for working with data in a high performance, connected fashion. Using a DataReader can be much faster than using a DataSet. Were going to try to take advantage of this in our architecture.
Many, if not most, web sites (and systems) read from a database much more than they write to one. It would be nice if there were an encapsulation of the two ADO.NET layers that would present a single API into our SQL data. This mechanism should hide the differences in API's between the DataSet and the DataReader. This, if you recall, is one of our requirements.
Introducing SQLDataSQLData is a concept-turned-prototype that was created to abstract and unify the DataSet and DataReader into a single API. The SQLData is implemented as a struct rather than as a class for performance reasons. If SQLData were a class, it would have to be created using the new operator; this would incur both memory and object-creation penalties. One of our requirements is to try to avoid using the new operator. A general rule to follow is that not doing something is usually faster than doing it. On a large website with lots of traffic, performance issues are easier to fix at the beginning of a project than near the end. Because SQLData is a struct, it is value-based rather than a reference (classes are references and must be created using the new operator). This means that SQLData is allocated on the stack, as would be the case in a simple int data type.
Figure 2 SQLData Encapsulates the DataSet and DataReader
Figure 2 illustrates the main idea behind the SQLData struct: The SQLData struct becomes our access strategy. Only SQLData has to deal with and understand the differences between the DataSet and DataReader. Lets look at some code that illustrates how SQLData hides the complexity. The code below creates an Employee object and loads a read-only employee record. It then asks for the 'FirstName' column.
public
Simple enough. Let's look at the Employee class and see what it takes to implement this logic.
Notice that the Load method calls SQLData.OrphanLoad. SQLData provides two sets of methods. One set is prefixed with Orphan and lets the SQLData struct know to act as a stand-alone object; another, prefixed with Collection indicates to SQLData that it is to operate as a collection. The SQLData struct allows us to load and access data without worrying about the underlying ADO.NET access mechanism being used.
This is not, however, all SQLData can do for us. SQLData can act as a bookmark -- in this context, a reference to an individual row in a set of data. The term bookmark is not new, as the ADO Recordset has a property named Bookmark. One SQLData struct can act as a bookmark into another SQLData struct. An Employee object housed in a collection uses its local SQLData struct to point to a row in the Employees collection. For instance, an Employees collection object can retrieve all of the employee records from the database, then create an Employee object and instruct it to point to a row of data in the collection. The SQLData struct does all of this on behalf of the Employees collection by looping through the data in the underlying DataSet or DataReader and passing itself as a bookmark to the individual Employee object. Thus, an Employee object uses its SQLData to hold the actual data when it exists as an orphan or uses it as a bookmark into an Employees collection.
An illustration here might prove useful. The Employees collection in Figure 3 contains ten employee records. Each Employee object is using its SQLData struct as a bookmark into the collection. This differs from the previous code sample, in which an individual Employee object was created. In that case, the Employee objects SQLData actually contained the data rather than acting as a bookmark into a collection. The SQLData struct hides all of this from the developer.
Figure 3 SQLData acting as a bookmark into another SQLData struct
A special case exists in the SQLData struct that allows for a significant performance gain. Figure 3 shows a unique object for each row of data in our collection object. The performance gain can be realized by using the ObjectCreation enum. Lets look at how this is used.
// How should the collection deal with object creation issues
// Create an Employees collection and load all employees
foreach SyntaxThere are a few reasons why only the foreach syntax was chosen for the iteration of objects in our collection instead of an indexer or some other mechanism. This syntax forces the developer to declare the each part within the foreach statement itself. For example, the following code will not compile because the Employee object is declared outside the foreach parenthesis:
// Declare our employee object here, WILL NOT COMPILE !!!
The developer cannot accidentally hang on to an instance outside of the foreach loop. Its not foolproof, but it goes a long way in avoiding misconceptions, especially when using ObjectCreation.Single, where only one object exists in the collection anyway.
However, this is not the only reason to use the foreach syntax. There is something very interesting here that one could easily gloss over, and its related to the compile error shown above. The foreach syntax is implemented via the IEnumerator interface and objects are returned through this method.
Notice that the return type of the Current property is object yet, as observed in the foreach loop above, no typecasting was done. No typecasting is required for the same reason that trying to declare the each part of the foreach loop outside of the parenthesis generates a compile error. A foreach loop must have the concrete type Employee within the foreach loop parenthesis because the compiler does the required typecast for us based on the concrete type.
This very convenient capability of the foreach syntax becomes key to our SQLData struct concept. The SQLData struct contains all of the data in our system, either in a DataSet or a DataReader. Furthermore, our SQLData struct has no idea what kind of objects it actually contains, so it is forced to work with a collection of type object. If it werent for the foreach syntax, there would either be a lot of ugly typecasting or plenty of needless class derivations simply to return a concrete data type rather than object.
Dont overlook the foreach syntax, it offers a built in typecast -- something which an indexer doesn't.
SQLDataEnumeratorIn order to support the foreach syntax, a generic class is needed that inherits from IEnumerator and is capable of iterating over our SQLData struct. The class is called SQLDataEnumerator. This capability means that SQLDataEnumerator can iterate over either a DataSet or a DataReader. Below is a code snippet demonstrating how the Employees collection implements the foreach syntax by using SQLDataEnumerator.
The SQLDataEnumerator constructor is shown below. Notice that the Employees collection passes this as the first parameter. The SQLDataEnumerator expects an ISQLCollection interface as its first parameter. Well talk about that in the next section.
internal
SQLData and InterfacesWith the use of the interface mechanism the SQLData struct obviates the need to know concrete class types. Base classes with virtual methods could have been used in place of interfaces; however, its quite easy to hide interfaces from the consumers of our classes. Inheriting from a class instead of an interface means that all methods in the base class become public. This can be overcome, but why bother? Only the SQLData struct and our internal namespace should know about these interfaces. Since SQLData doesnt want to know concrete class types such as our Employees or Dependents classes, it asks you to implement two interfaces:
ISQLCollection for the collection classes, i.e., Employees and DependentsISQLObject for the individual classes, i.e., Employee and Dependent
Lets take a look at the interface definitions, and well see how they help us.
interface
The only method an ISQLCollection must implement is the i_CreateSQLObject method, which is called by the SQLData struct in order to create individual business objects. SQLData does so when creating individual objects to represent a row of data in its collection (see Figure 3).
Below is all that our Employees collection must do to load all of the employees in our database. LoadAll takes the two enums we discussed earlier. The call to m_Data.CollectionLoad is passed the this pointer, thereby providing the SQLData an ISQLCollection interface. SQLData now knows it is residing in a collection, rather than in an individual object.
Figure 4 SQLDatas Interface Usage
The m_Objects list in the SQLData struct is a collection of ISQLObjects (Employee objects) and the m_ISQLColl data member points to our Employees collection. Interestingly, both the Employees and Employee object contain a SQLData struct. The SQLData struct in the Employees collection actually contains the data, whereas the SQLData struct in the Employee object is acting as a bookmark. Technically, there is a third scenario: an Individual Employee object may be created, in which case the SQLData is just plain old data -- no collection, no bookmark.
Lets look at SQLDatas (simplified) collection load method so we can see how this all happens:
The Hierarchical ModelWe have chosen to express our business objects (or middle tier) as a set of hierarchical objects. This allows us to iterate over our data in a very natural way. XML is such a nice way to represent data because of its ability to represent hierarchical data. Our employee-dependent relationship is hierarchical, so why not express our middle tier hierarchically also?
string
As is the case with iterating using the foreach syntax, both saving and deleting objects are hierarchical operations. For instance, we can load a writeable collection of Employees and then change each employees FirstName to Bob. We could continue by iterating over each employees Dependent collection, changing each dependents FirstName to Joe. We could commit all of the changes to the database simply by calling Employees.SaveAll, which would save all of the changes made to our dependent data as well.
This is all done through the ISQLObject interface described earlier. When we save data, we save it from the top down; i.e., Employees, then Dependents. We save from the top down so that we wont get into trouble with the referential integrity that may exist in our database. If you look at the i_PostSave method in the Employee class, youll notice that this is where we save our Dependents child collection (emphasis PostSave). Accordingly, when we call DeleteAll, we delete from the bottom up, again to comply with database referential integrity rules. Lets look at the Employee objects implementation of ISQLObject.i_PostSave:
Strongly Typed DatasetsThe experienced ADO.NET developer must be asking by now, Why not just use the Server Explorer and drag and drop a DataSet, Connection, and DataSetCommand onto a form, and generate the desired Employees collection class through the wizard mechanism?
This is exactly what I did. I created a class through the wizard named tdsEmployees where tds stands for Typed DataSet. The tdsEmployees class inherits from DataSet. Below is a code sample for comparison purposes. The code sample selects all of the employees in the database using both the Employee and the tdsEmployees classes.
//----------------------------------------------------// Employees Object - Loop through all of them//----------------------------------------------------
The pro side of the tdsEmployees strongly typed class
The tdsEmployees class was generated in about a minute, and true to its name, it is strongly typed. The wizard asked for some database information, and then it created the tdsEmployees class with all of its get and set property accessors, i.e., FirstName, LastName, and so on.
Quite a few methods in the tdsEmployees class were also generated by the wizard for me based on the structure of the Employees database table. Here are just a few to give you a feel for what a wizard-generated strongly-typed DataSet contains:
The con side of the tdsEmployees strongly typed class
The obvious difference at first glance is that using the tdsEmployees class requires my SQL query and setup work to live outside of the class. In other words, for tdsEmployees to become a real middle-tier object, weve got some work to do. As noted on the pro side, derivation is the intended path to turn the tdsEmployees object into something more useful that could contain our business logic. So we would need to create a class that inherits from our tdsEmployees class (you can only inherit from one class).
Also, unlike the hierarchical set of objects that we created, the tdsEmployees is a collection only -- a collection of one, maybe, but still a collection. There is no single tdsEmployee object. There is an EmployeeRow class that inherits from the ADO.NET DataRow class, and it would be possible to derive an Employee object from EmployeeRow, but you would have some work to do because of the internal structure of the tdsEmployees class. Also, when you inherit from a class in C# it is always a public inheritance. Unlike in C++, in C# you cannot inherit using protected or private keywords. This means that you might need to hide and/or overload some methods to ensure a coherent interface.
Finally, tdsEmployees has no way to use a DataReader for fast performance when desired. You would either have to wedge it in (which would be extremely difficult) or use another object entirely. DataSets may use DataReaders underneath the covers, but for performance reasons you want to skip the DataSet entirely and use a DataReader if you can for read-only data.
PerformanceAfter moving the SQLData struct from concept to prototype I was curious about its performance as compared to a strongly typed dataset. I was also eager to know whether bypassing the DataSet and going directly to the DataReader would provide a worthwhile performance boost.
The first order of business was to write a Timer function to time our tests. Eric Gunnerson provided a good starting point in his book A Programmers Introduction to C# published by Apress. This book proved invaluable to me when it came to issues related to the C# language and certain system namespaces.
Once I had a generic timing method that I could pass a delegate (C++ programmers think function pointer) to, I was able to gather the necessary performance statistics.
The first test I ran accessed 2000 employee records looping through each employee and accessing all six of its fields in each object. I did this test in four different ways:
1) Using the tdsEmployees collection (wizard generated strongly typed dataset)2) Using our Employees collection with RWMode.Read and ObjectCreation.Single3) Using our Employees collection with RWMode.Read and ObjectCreation.Unique4) Using our Employees collection with RWMode.Write and ObjectCreation.Unique
Ive taken a little creative license with the following code to make it more readable. I think it is important to know how the timings were gathered (all of the real code is available at the end of this document).
using
The statistics were gathered on a 600 MHZ Dell Inspiron 3800 laptop running Windows 2000 Server Edition - SP1 with 256 meg of ram. The test code was housed in a C# console application with both the MiddleTier namespace and the console application compiled for Release mode.
The legend is as follows: T = Total time, M = Min time, X = Max time, A = Average time, and GC = the time it took to do a garbage collection after the test. All times are in seconds. In this particular test suite T, M, X, and A are all the same because I ran only a single iteration. I ran each test ten times in a row, however, to demonstrate the predictability. Notice the blip in the time on the third test suite. This would happen periodically due to disk access, but could happen in any area. Still, the tests and times are very predictable and repeatable.
NOTE: The observant reader will notice a direct correlation between the garbage collection time and the overall time.
If you look at the times for tdsEmployees, youll notice that it took about 245 milliseconds or roughly a quarter of a second to retrieve and loop through all 2000 employees accessing all six fields. Also, the garbage collection time was roughly another .020 milliseconds after each test. Compare this with our read-only Employees collection using our ObjectCreation.Single performance hint. The Employees collection took about 100 milliseconds (one tenth of a second) to do the same thing with only .006 milliseconds spent in garbage collection.
The Employees collection completed the task in only 40% of the time it took the tdsEmployees collection to do the same amount of work. Garbage collection also was helped by the ObjectCreation hint, going from .020 in the tdsEmployees test to .006 in the Employees collection.
You might be surprised to see that the Employees test using the Read/Unique combination took longer than the Write/Unique combination. After all, RWMode.Read uses the ADO.NET DataReader while RWMode.Write uses the ADO.NET DataSet. Arent DataReaders faster than DataSets? The reason for this is that in the Employees Read/Unique combination, each Employee object must copy the data out of the DataReader and into its own local buffers. DataReaders support the reading of a forward-only stream of records; multiple rows of data cannot be held onto simultaneously. Take a look at the way the Employee object handles the i_SetBookmark method.
void
How about a more realistic test? I mean, who retrieves 2000 employees per web hit anyway?
Here are the numbers for a test in which a single record was fetched from the employee table. In order to reach any measurable amount of time, I had the test routine retrieve a single employee record 3000 times accessing all six fields each time. Think of this test as 3000 individual hits against a web site.
The Employee numbers were based on a read-only (individual) Employee object (which uses the DataReader). When I ran the same test using a writeable Employee object, there was no difference between the times of the tdsEmployees collection and a writeable Employee object. So in 3000 web hits I saved about six to seven seconds using a read-only Employee object.
ConclusionThe .NET Framework is a tremendously productive and rich environment. I created the entire code base for this article in about a week. ADO.NET is a significant departure from ADO and I recommend that you begin to study it seriously now, before youre facing an actual .NET deadline. The DataReader object can yield a significant performance boost in certain situations as was demonstrated by the SQLData struct and the performance statistics presented in this article. Although allocating objects is very fast in the .NET Framework, not allocating them is even faster. The performance numbers and the time to cleanup afterwards are, not surprisingly, linked. The author is not unaware of the inadequacy of hierarchical middle-tier architecture in certain situations; sometimes database views must be created to retrieve data efficiently where a hierarchical model would prove too slow. This paper was meant to be a learning exercise -- it was not intended to present the SQLData struct as production code, although someone could attempt to do so. The lingering question this paper leaves unanswered is how the middle tier handles incoming XML. How do we trigger all of the business logic? Stay tuned.
The Source CodeThe source code is available for viewing online below and was color-coded by an online tool available at csharpindex.com/colorCode. The entire Microsoft .NET MiddleTier solution is available for download below as well.
There are some areas of unfinished business in the code however. For example, exception handling is weak. Also, our four business objects currently have a use once only policy. I did not add the ability to reuse them. For example, if you created an Employee object and then called its Load method followed by another call to Load or AddNew the results would be unpredictable. Correcting this shortcoming would not be difficult, however.

It's normal to have a single package which had conditionally included source files. But what you are describing seems to be the case of the same source file going into two different packages. I don't know why that would ever be useful or interesting. But, yes, it could be done, if both of the two different packages used the same name at the source code level.

One of the secret ingredients of practical software engineering is to ensure the solutions are simple and small. That’s essentially what the hype around serverless implementations is all about since serverless applications scale automatically with demand and remove the maintenance burden from developers. Of course, since it’s all automated, you’re going to lose some control and visibility, but the time and effort savings are hard to argue with.
In this article, we’re going to use Python and Amazon Web Services (AWS) Lambda to implement a simple REST API by doing the following:
- Create a Lambda function using Python
- Connect the Lambda function to AWS API Gateway and AWS DynamoDB
- Managing access to the function with AWS Identity & Access Management (IAM) policies
In the quest for simplicity, we’ll use AWS CloudFormation to define as much of this process as possible.
Recall that a REST API is simply a way to store and retrieve information with stateless protocols. In this case, our REST API is going to handle information about people’s pets. To create it, we’ll:
- Implement a POST endpoint to submit pet information to the API
- Enable a GET endpoint to retrieve pet information
- Use an AWS DynamoDB table to store pet information
Here’s our implementation plan:
- Define the REST API
- Set up the serverless infrastructure
- Code the Lambda functions
- Create the API gateway
- Deploy and test the API gateway
Python And AWS Lambda – Overview
Just in case you’re new to AWS or their serverless platform known as AWS Lambda, let’s run through a quick overview:
- Why AWS Lambda? The Lambda platform allows you to create and configure a function that runs in the AWS environment. An overwhelming benefit of these functions is that you only pay for the resources needed to execute the function, making them an attractive option for organizations looking for a scalable and cost-effective way to add cloud functionality.
- How to Create a Lambda Function:
- Create a handler function where we can provide the code. The handler accepts JSON formatted input and returns the same.
- Specify the runtime environment (ie., the version of Python to use)
- Define a trigger that invokes the function. For this example, we’re going to create two Lambda functions.
- Because Lambda functions are stateless, we’ll create a DynamoDB table to store the information between requests.
- We’ll also need to create an IAM role that allows our Lambda functions to access the DynamoDB table.
You can find all of the code for this project in my GitHub repo. The repo includes an API document and a CloudFormation template that will make it easier to get everything running in your AWS account.
- Birthday
- Owner’s name
- A unique identifier for each pet
You can view the API in my GitHub repo (see API.json), or you can just view it alongside the interactive documentation for it in the SwaggerHub repo. The API defines two endpoints:
- A GET endpoint, which allows us to find a pet using the unique identifier
- A POST endpoint, which enables us to add new pets to our Dynamo database
2 — Set Up The Serverless Infrastructure
We’ll use a CloudFormation (CF) template to set up the infrastructure for this example. You have two choices:
- If you want to follow along, you’ll need to log in to your AWS account and create the CF stack from the CloudFormation home page. AWS provides good instructions for creating a new CloudFormation stack here.
- Or you can use my CloudFormation.json CF template
If you want to create your own, you can:
- Select Create stack and choose the Upload a template file option
- Selecting the template file and click Next
- Name the new stack PetsAPI or something similar and then click Next
- Keep all the default options on the Configure stack options page and click Next
- At the bottom of the Review page, check the option to allow CloudFormation to create an IAM role.
It should only take a minute or two to create all the elements of the new stack. If you’d prefer to provide the infrastructure manually, you’ll need to create:
- A DynamoDB table named “Pets” with a primary key named id.
- An IAM Role that grants a Lambda function with permission to:
- Write and read from the “Pets” table
- Create log groups, a log stream and write log events
- Two Lambda functions, one for the GET operation, and one for the POST operation.
- Set the runtime to Python 3.7
- Configure the function to use the IAM role you created.
Now that we’ve created the infrastructure, we’ll edit the code in each of the Lambda functions to handle adding and retrieving pet objects from the database table.
3 — Code The Lambda Functions
On the AWS console, navigate to the Lambda home page where you should see the two functions we created previously.
Let’s start by implementing the POST endpoint. If you set up your infrastructure with the CF template, the function is called PetLambda-Set.
- Select the function name to edit it
- Navigate to the Code tab below the function overview
- Select index.py to view the code for the Lambda:
We’re going to use the boto3 library, which provides the AWS SDK for Python. We’ll keep the code simple for now, but you could experiment with adding validations and exception handling. Using boto3, we’ll connect to the DynamoDB table and insert a new record. If you’re following along, copy the code below, and replace the Lambda code with it:
import boto3 def lambda_handler(event, context): client = boto3.resource('dynamodb') table = client.Table('Pets') response = table.put_item( Item={ 'id': event['id'], 'name': event['name'], 'breed': event['breed'], 'gender': event['gender'], 'owner': event['owner'], 'birthday': event['birthday'] } ) return { 'statusCode': response['ResponseMetadata']['HTTPStatusCode'], 'body': 'Record ' + event['id'] + ' added' }
If you want to test the Lambda function, Select the Test tab, create a new test from the hello-world template, and use the example dataset shown below:
{ "id": "d290f1ee-6c54-4b01-90e6-d701748f0851", "name": "Hansie", "breed": "Dachshund", "gender": "Male", "owner": "Mike", "birthday": "2012-05-15" }
The response should look similar to that shown below:
{ "statusCode": 200, "body": "Record d290f1ee-6c54-4b01-90e6-d701748f0851 added" }
Now let’s follow the same steps to update the PetLambda-Get function. The code below:
- Connects to the DynamoDB table
- Creates a query using a key composed of the id
- Returns either the pet object or an HTTP 404 Not found error
import boto3 def lambda_handler(event, context): client = boto3.resource('dynamodb') table = client.Table('Pets') response = table.get_item( Key={ 'id': event['id'] } ) if 'Item' in response: return response['Item'] else: return { 'statusCode': '404', 'body': 'Not found' }
You can test this Lambda by sending in the following test data:
{ "id": "d290f1ee-6c54-4b01-90e6-d701748f0851" }
4 — Create The API Gateway Via AWS Console
With our two Lambda functions created and connected to the database, it’s time to add an API Gateway to expose the API functionality. On the AWS Console, navigate to the API Gateway home page and select the Build option to create a REST API:
At this point, you can:
- Manually set up your API using the Build button
- Import the configuration from a Swagger File or Open API 3 file
Let’s do the following:
- Click the Import button and select the Import from Swagger or Open API 3 option
- Click the Select Swagger File button.
- My GitHub code repository contains a file named API.json. Choose that file, and select Import. After the import process has finished, you should see the pet resource defined with a GET and a POST resource endpoint:
Now we’ll connect the GET and POST endpoints to each of our Lambda functions:
- Click Set up now for the POST endpoint first.
- Set the Integration type to Lambda Function. The region is the same one where you defined your functions.
- Type PetLambda-Set into the Lambda Function field and select Save.
- AWS automatically adds permissions for the API Gateway to call your function so all you need to do is select OK at the prompt.
- Test the POST endpoint by selecting the Test option on the client block and entering the original dataset that we used to test the Lambda function above. The POST endpoint accepts a Request Body in JSON format by default:
Configuring the GET endpoint is similar, although we’ll need to configure a way to map the query string to the Lambda parameters:
- Click Set up now for the GET endpoint.
- Set the Integration type to Lambda Function. The region is the same one where you defined your functions.
- Type PetLambda-Get into the Lambda Function field and select Save.
- AWS will prompt you again to add permissions for the API Gateway to call your function, so click OK.
- Select the Method Request box
- Under URL Query String Parameters add a query string named id, and mark it as required.
- Click the checkmark to save it.
- Select Method Execution to return to the main configuration page for the GET endpoint.
- Select the Integration Request box.
- Under Mapping Templates, select When there are no templates defined (recommended).
- Select the option to Add mapping template.
- Set the Content-Type to application/json and select the checkmark to save the value.
In the Generate Template box, paste the following:
{ "id": "$input.params('id')" }
This configuration will map the query string parameter to an input parameter for the Lambda. Click Save when you’re done.
5 — Deploy And Test API Gateway
Okay, time to deploy our API and make sure everything is set up and working properly. From the main screen for your API, click on Actions, and choose Deploy API.
Choose [New Stage] from the Deployment stage dropdown, and then enter a name (such as Test) and a description. Click Deploy when you’re done.
AWS will now deploy your API and make it available to be invoked on the Web. You’ll find a custom URL at the top of the page, and options below to enable throttling and various security options.
Copy the URL to your browser and add /pet?id=d290f1ee-6c54-4b01-90e6-d701748f0851 to the end of it. If you followed this example and tested your Lambda with the data set I provided, you should see the JSON object returned in your browser.
You can also use PostMan, Insomnia, or other API tools to post different datasets to the endpoint. You’ll need to add /pet to the end of the URL provided for you.
Python And AWS Lambda – Wrapping Up
Remember that AWS charges you for everything that’s running on your account, so when you’re done with the example in this post, don’t forget to clean up the API, Lambdas, and other infrastructure. The simplest way is:
- On the API Gateway home page, select the API Gateway you created, and choose Delete from the Actions dropdown.
- From the CloudFormation home page, select the stack you created and click on the Delete option at the top of the page.
- AWS should remove everything within a few minutes.
If you’d like to learn more about Amazon’s API Gateway, the Developer Guide is an excellent place to start. As you can see from the example above, if you have an API document, it doesn’t take much to provision Lambda functions and configure them behind an API gateway.
If you want to explore more of what you can do with Python and AWS Lamda, try our pre-built Cloud Computing Python Environment for Windows, Mac and Linux.
It bundles up Python 3.8.2 and boto3 so you can just install it and start driving your AWS implementation using Python right away! | https://sweetcode.io/how-to-create-a-serverless-rest-api-with-python-and-aws-lambda/ | CC-MAIN-2021-25 | refinedweb | 1,964 | 58.92 |
Hello,
I’m creating a map interface with leaflet and sadly, leaflet doesn’t support framework issues. So I started making a leaflet-draw wrapper by using vanilla js (leaflet.draw, drag, handlers).
My problem is that as to use this wrapper in parent component, I’ve used mounted() hook to mount the draw buttons and functions. Then I started having headache issues.
Please let me know if you need a test project. It’s over 8,000 lines so I will just send you my test project instead of making a jsfiddle.
- even vanilla js is it’s in mounted() hook keyword ‘this’ doesn’t work in vanilla js event function
- using commit to mutate states, I have to use actions(store.dispatch) to mutate the state which I really don’t understand why I have to use actions in event function to mutate the state.
here’s an simple part of example
import storefrom ‘./store/index.js’
mounted() { this.$nextTick(() => { .. objectLayer.on("layeradd", function(e) { this.$store.getters.test // this 'this' won't work store.commit('setData', payload) // this store.commit() won't work cuz commit of undefined error store.dispatch('updateData') // will only work } } } | https://forum.vuejs.org/t/commit-of-undefined-in-mounted-valina-js-event-function/98431 | CC-MAIN-2020-29 | refinedweb | 197 | 69.28 |
Migrate Your WordPress Site to the Jamstack
WordPress is the most popular content management system on the planet, powering about a third of the websites online today.
If you’re working on one of the roughly 1 in 3 websites powered by WordPress and wish you could migrate your development workflow to the Jamstack, I have good news! It’s possible to move your WordPress websites to the Jamstack today.
And what’s even more exciting is that your content creators don’t need to change their current workflow! They can continue to use the WordPress admin dashboard to manage content and their changes will trigger a rebuild of your new, blazing fast Jamstack site.
In this post, we’ll walk through migrating a WordPress site to Gatsby, a popular Jamstack framework powered by React and GraphQL.
If you prefer video, we’ve got you covered!
This post is an expanded version of a project I built with Zac Gordon on Learn With Jason. In about 90 minutes, Zac and I migrated a WordPress site to Gatsby. Watch Zac Gordon teach us how to migrate WordPress sites to the Jamstack on Learn With Jason.
If you prefer short videos that only focus on code and don’t waste any time, I also created a 30-minute video tutorial that covers all the steps in this project. You can learn how to move your WordPress site to Gatsby on egghead.
NOTE: The lessons from the egghead course are also embedded in this tutorial so it’s easy to watch and reference the code.
Set up WordPress
The first things we need to migrate a WordPress site to the Jamstack is a WordPress site. In this tutorial, we’re going to use, but you can follow along using your own site if you prefer.
Install WPGraphQL and WPGraphiQL
The heart of a Jamstack-friendly WordPress site is pulling WordPress data from an API instead of using the built-in template system. One of the most approachable options for accessing WordPress data via API is WPGraphQL.
Because these plugins are developer-focused, they’re not available through the standard WordPress plugins search. Instead, we need to install them from GitHub.
We need two plugins:
- WP GraphQL — this enables a GraphQL API that allows access to all public WordPress data through an unauthenticated GraphQL API. (There’s also an authenticated API for privileged access, but we won’t go into details on that in this post.)
- WP GraphiQL — this is technically optional, but it adds a new tab inside the WordPress admin that allows us to quickly try out GraphQL queries and see data coming back.
To install the plugins, log into the server where your site is hosted and clone the plugins into the
wp-content/plugins directory:
ssh <user>@<domain> cd /path/to/your/wp-content/plugins/ git clone --depth=1 --single-branch git clone --depth=1 --single-branch
This will add the latest files to your site’s plugins directory without including unnecessary Git metadata.
Activate the GraphQL plugins
Once the plugins are installed, we need to activate them. Head to your WordPress admin dashboard, then click the “Plugins” option from the left-hand menu.
We should see both WP GraphQL and WP GraphiQL as installed, but not activated.
Click the “Activate” link for both WP GraphQL and WP GraphiQL.
Write our first GraphQL query in WP GraphiQL
Click the new “GraphiQL” menu option at the left-hand side. This brings up the GraphiQL interface inside our WordPress dashboard.
Choose fields in the explorer at the left-hand side to build out a query. For example, if we want to load our site’s pages, we can run this query:
query MyQuery { pages { nodes { title uri content isFrontPage } } }
Great! We’ve now got a functioning GraphQL API for WordPress that we can use to power our Jamstack frontend!
Create a new Gatsby site
Before we can use our WordPress data, we need to create a new Jamstack site that will display it.
In this example we’ll use Gatsby, an open source, React-based framework that specializes in pulling data from third-party sources.
To create a new site, run the following commands:
# create a new Gatsby site in a directory called `wordpress-jamstack` # using the Hello World Gatsby starter npx gatsby new wordpress-jamstack gatsbyjs/gatsby-starter-hello-world # move into the folder cd wordpress-jamstack/
This generates a new site in a directory called
wordpress-jamstack with a bare-bones Gatsby site.
NOTE: There are lots of additional options for starting a new Gatsby site with WordPress that come with batteries included. One great example is Alexandra Spalato’s
gatsby-theme-wordpress-blog. We’re intentionally building this site from scratch to make sure we understand how Gatsby and WordPress work together under the hood.
Install and configure
gatsby-source-graphql
Gatsby uses source plugins to load data. One of the most powerful source plugins is
gatsby-source-graphql, which allows us to use any GraphQL API as a data source in Gatsby.
Since we just created a GraphQL API for our WordPress site, this is a perfect option for loading our WordPress data in Gatsby!
Install the plugin with the following command:
npm install gatsby-source-graphql
After installing the plugin, we need to load it by modifying
gatsby-config.js:
/** * Configure your Gatsby site with this file. * * See: */ module.exports = { - /* Your site config here */ + plugins: [ + { + resolve: 'gatsby-source-graphql', + options: { + typeName: 'WPGraphQL', + fieldName: 'wpgraphql', + url: '', + } + } + ] }
Save this, then start the Gatsby development server by running:
npm run develop
Once the site finishes starting up, open in your browser to see Gatsby’s version of GraphiQL.
In Gatsby, writing a query to load WordPress data is almost exactly the same as the one we used in WP GraphiQL, except Gatsby wraps all WordPress queries in
wpgraphql — the
fieldName we set in our config — to avoid naming collisions with other data sources.
Add the following query in GraphiQL:
{ wpgraphql { pages { nodes { title uri content isFrontPage } } } }
After executing the query by pressing the play button, we’ll see our WordPress data loaded in Gatsby!
Create pages from WordPress content
Now that we have a Gatsby site that has access to our WordPress data, we can start creating pages.
To create pages in Gatsby, we need three things:
- Data to display on the page
- A template component to define the page layout
- A call to the
createPagesAPI exported from
gatsby-node.jsto combine the data and template together into pages
We have the data from WordPress now, so we can create our template component, then create pages.
Create a template component for pages
A template component in Gatsby is a standard React component. Gatsby passes in several props to the component when it creates pages, so it’s probably a good idea to take a look at what those are.
Create a new files called
src/templates/page-template.js and put this inside:
import React from "react" const PageTemplate = props => { return <pre>{JSON.stringify(props, null, 2)}</pre> } export default PageTemplate
Once we’ve saved this file, we’re ready to actually create pages.
Create pages in
gatsby-node.js
To create pages, create a new file in the root directory (next to
gatsby-config.js) called
gatsby-node.js. Inside, let’s add a
createPages API call:
exports.createPages = async ({ actions, graphql }) => { // query for WordPress page data const result = await graphql(` { wpgraphql { pages { nodes { id uri } } } } `) // pull the page data out of the query response const pages = result.data.wpgraphql.pages.nodes // loop through WordPress pages and create a Gatsby page for each one pages.forEach(page => { actions.createPage({ path: page.uri, component: require.resolve("./src/templates/page-template.js"), context: { id: page.id, }, }) }) }
After saving this file, we can stop the server (press
control + C), then run
npm run develop again.
Once the site has started, visit. We can see everything that Gatsby passes to page components, including the
id value we passed in
context:
This doesn’t look like much right now, but it gives us the page ID, which will let us load page-specific data in our template component.
Write a GraphQL query to load page content from WordPress
Collocating GraphQL queries with the components that use them is a great way to keep your codebase understandable. Because of this, we’re going to query for individual page data using the page ID in the template component itself.
Anything passed in the
context object is also available as a GraphQL variable, so we can use the
id to load content for each page by adding the following query:
import React from "react" + import { graphql } from "gatsby" + + export const query = graphql` + query($id: ID!) { + wpgraphql { + page(id: $id) { + title + content + } + } + } + ` const PageTemplate = props => { return <pre>{JSON.stringify(props, null, 2)}</pre> } export default PageTemplate
Once we save this, the page at will update to include a new
data prop that contains the result of this query.
Alright! Now that we have content, we need to write some markup to actually display it in a reader-friendly way.
Display the content in the page template
WordPress returns markup and HTML-encoded entities, so we need to use
dangerouslySetInnerHTML to make sure our content displays properly.
To use our page data, we can grab just the
data prop in our component, then drill down to the page content and display those values:
import React from "react" import { graphql } from "gatsby" export const query = graphql` query($id: ID!) { wpgraphql { page(id: $id) { title content } } } ` - const PageTemplate = (...args) => { - return <pre>{JSON.stringify(args, null, 2)}</pre> + const PageTemplate = ({ data }) => { + const page = data.wpgraphql.page + return ( + <> + <h1 dangerouslySetInnerHTML={{ __html: page.title }} /> + <div dangerouslySetInnerHTML={{ __html: page.content }} /> + </> + ) } export default PageTemplate
Save and check out — it’s working!
Add a shared layout and styles
To make our Gatsby site look more like a real website, we need to add a layout — a shared header in this case — and styles.
Create a shared
Layout component
Creating a Layout component requires a standard React component that wraps whatever content is passed to it (as the
children prop) with markup to give the page semantic structure.
Create
src/components/layout.js, then add the following code:
import React from "react" import { Link } from "gatsby" const Layout = ({ children }) => { return ( <> <header> <Link to="/" className="home"> Migrate WordPress to the Jamstack </Link> </header> <main>{children}</main> </> ) } export default Layout
This sets up a
header element with a link to go back to the home page and a
main element that contains the page content.
Use the layout in pages
Once we have a layout component, we need to import it in our page template and wrap it around the output:
import React from "react" import { graphql } from "gatsby" + import Layout from '../components/layout'; export const query = graphql` query($id: ID!) { wpgraphql { page(id: $id) { title content } } } ` const PageTemplate = ({ data }) => { const page = data.wpgraphql.page return ( - <> + <Layout> <h1 dangerouslySetInnerHTML={{ __html: page.title }} /> <div dangerouslySetInnerHTML={{ __html: page.content }} /> - </> + </Layout> ) } export default PageTemplate
Once we’ve saved these changes, we can head to to see the header at the top of the page.
Add basic styles
Adding styles helps our site look a bit more polished.
Create
src/styles/layout.css, then add the following:
html, body { margin: 0; font-family: -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, Helvetica, Arial, sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol"; } header { background: darkblue; padding: 1rem 5vw; } header a { color: white; display: inline-block; margin-left: 0.75rem; } header .home { font-weight: 800; margin-left: 0; text-decoration: none; } main { margin: 2rem auto; max-width: 54ch; width: 90vw; }
This CSS makes the header blue with white text and adds some spacing around elements on the page.
To apply our styles, we need to import the stylesheet in our
Layout component:
import React from "react" import { Link } from "gatsby" + import "../styles/layout.css" const Layout = ({ children }) => { return ( <> <header> <Link to="/" className="home"> Migrate WordPress to the Jamstack </Link> </header> <main>{children}</main> </> ) } export default Layout
After saving this change, our page at will start looking a little more stylish.
NOTE: Gatsby has built-in support for multiple styling approaches. You can likely use whatever flavor of CSS you prefer.
Create pages from WordPress posts
In WordPress, content can be split up into multiple content types. By default, there are “pages”, which we’ve already handled, and “posts”, which are most commonly used to power blogs.
Our WordPress site is using both pages and posts, so we need to write additional code to create Gatsby pages for each WordPress post.
Create a page template component
Fortunately, the process for creating pages from WordPress posts is very similar to the process for creating WordPress pages.
To start, we can duplicate
src/templates/page-template.js and name the new file
src/templates/post-template.js. Inside, we need to make the following edits:
import React from "react" import { graphql } from "gatsby" import Layout from "../components/layout" export const query = graphql` query($id: ID!) { wpgraphql { - page(id: $id) { + post(id: $id) { title content } } } ` - const PageTemplate = ({ data }) => { - const page = data.wpgraphql.page + const PostTemplate = ({ data }) => { + const post = data.wpgraphql.post return ( <Layout> - <h1 dangerouslySetInnerHTML={{ __html: page.title }} /> - <div dangerouslySetInnerHTML={{ __html: page.content }} /> + <h1 dangerouslySetInnerHTML={{ __html: post.title }} /> + <div dangerouslySetInnerHTML={{ __html: post.content }} /> </Layout> ) } - export default PageTemplate + export default PostTemplate
Now we’re ready to actually load post data and create Gatsby pages.
Create pages from WordPress post data in
gatsby-node.js
Inside
gatsby-node.js, we need to add to our GraphQL query, then add another block of code that pulls the posts out of the response and creates pages for each one.
To differentiate posts from pages, each post will have its URL prefixed with
Make the following changes to put this in place:
exports.createPages = async ({ actions, graphql }) => { const result = await graphql(` { wpgraphql { pages { nodes { id uri } } + posts { + nodes { + id + uri + } + } } } `) const pages = result.data.wpgraphql.pages.nodes pages.forEach(page => { actions.createPage({ path: page.uri, component: require.resolve("./src/templates/page-template.js"), context: { id: page.id, }, }) }) + + const posts = result.data.wpgraphql.posts.nodes + + posts.forEach(post => { + actions.createPage({ + path: `blog/${post.uri}`, + component: require.resolve("./src/templates/post-template.js"), + context: { + id: post.id, + }, + }) + }) }
Stop the server and restart it, then visit one of your post URLs, such as.
Hey, that wasn’t so bad — we’re getting pretty close here!
Add support for WordPress block styles
With the release of Gutenberg, WordPress introduced a block-based editor that allows a slick visual editing experience that supports some stylized blocks like pull quotes.
If we want to avoid rewriting all the CSS to support those stylized blocks, we need to import the block styles from the official WordPress package.
Install
@wordpress/block-library
Our first step is to install the official WordPress block library:
npm install @wordpress/block-library
Import the stylesheet into the
Layout component
Once we have the package installed, we can import only the stylesheet in our layout component:
import React from "react" import { Link } from "gatsby" + import "@wordpress/block-library/build-style/style.css" import "../styles/layout.css" const Layout = ({ children }) => { return ( <> <header> <Link to="/" className="home"> Migrate WordPress to the Jamstack </Link> </header> <main>{children}</main> </> ) } export default Layout
After saving this, start up the server and head to a page with a styled block on it (such as) to see the WordPress block styles applied.
This looks pretty okay considering we didn’t write any custom styles.
Create a page to show blog previews
To allow site visitors to browse blog posts, we need to create a page that lists post previews.
To do this, we’re going to create a Gatsby page at
src/pages/blog.js, query for post data, and map over the results to create a list of previews:
import React from "react" import { graphql, Link } from "gatsby" import Layout from "../components/layout" export const query = graphql` query { wpgraphql { posts { nodes { id title uri excerpt } } } } ` const Blog = ({ data }) => { const posts = data.wpgraphql.posts.nodes return ( <Layout> {posts.map(post => ( <article key={post.id}> <h2> <Link to={`/blog/${post.uri}`} dangerouslySetInnerHTML={{ __html: post.title }} /> </h2> <div dangerouslySetInnerHTML={{ __html: post.excerpt }} /> </article> ))} </Layout> ) } export default Blog
Save this file, then head to to see the previews.
Use WordPress settings to configure your Gatsby site
WordPress has a full-featured set of tools for managing site settings that is friendly to non-developers, which means it’s more approachable for site contributors than modifying code.
WP GraphQL makes these settings available to our Gatsby site, so we can take advantage of this workflow to enable non-developers to update settings for our Gatsby site as well.
Let’s pull the site title from WordPress’s general settings to show how this can work.
To do this, update
src/components/layout.js with the following code:
import React from "react" - import { Link } from "gatsby" + import { Link, useStaticQuery, graphql } from "gatsby" import "@wordpress/block-library/build-style/style.css" import "../styles/layout.css" const Layout = ({ children }) => { + const data = useStaticQuery(graphql` + query { + wpgraphql { + generalSettings { + title + } + } + } + `) + + const { title } = data.wpgraphql.generalSettings + return ( <> <header> <Link to="/" className="home"> - Migrate WordPress to the Jamstack + {title} </Link> </header> <main>{children}</main> </> ) } export default Layout
Save and check out the site to see that the settings are being loaded. If you want to test this out, make a change in WordPress, then restart the Gatsby development server to see the changes.
Create Gatsby navigation from WordPress menus
WordPress menus allow content editors to control the navigation settings on the site. If we want to use those menus for our Gatsby site, we can!
Get the menu ID
To make sure we’re getting the right menu, we need to find the ID for the menu we want to use.
In GraphiQL (), run the following query:
{ wpgraphql { menus { nodes { id name } } } }
Look for the menu with the
name value of “Main Menu”, then grab its ID for use in the next section.
Load the menu items and make links relative
Now that we have the menu ID, we can update
src/components/layout.js to load the correct menu.
One important thing to note is that we also need to load the site’s URL from the
generalSettings query because WordPress makes links absolute by default. Using this value, we can loop through the menu links and remove the URL to make sure we have relative links.
import React from "react" import { Link, useStaticQuery, graphql } from "gatsby" import "@wordpress/block-library/build-style/style.css" import "../styles/layout.css" const Layout = ({ children }) => { const menu = useStaticQuery(graphql` query { wpgraphql { generalSettings { title + url } + menu(id: "TWVudToy") { + menuItems { + nodes { + id + label + url + } + } + } } } `) - const { title } = menu.wpgraphql.generalSettings + const { title, url } = menu.wpgraphql.generalSettings + // loop through the menu items and make the links relative + const items = menu.wpgraphql.menu.menuItems.nodes.map(item => ({ + ...item, + url: item.url.replace(url, ""), + })) return ( <> <header> <Link to="/" className="home"> {title} </Link> + {items.map(item => ( + <Link key={item.url} to={item.url}> + {item.label} + </Link> + ))} </header> <main>{children}</main> </> ) } export default Layout
Save these changes and look at — the WordPress navigation is now displayed in the header, and it works to navigate our Gatsby site!
At this point, our WordPress site has been fully migrated to the Jamstack: we’re loading pages, posts, settings, and menus into a fully functional Gatsby site.
All that’s left to do at this point is get this site deployed!
Deploy a WordPress-powered Gatsby site to Netlify using the Netlify CLI
To deploy the site, we need to have the code in a repository on GitHub, Bitbucket, or GitLab.
Once we have a repo available, we can commit our changes and push them to our repository:
# add all of the files in our site to git git add -A # commit the changes git commit -m 'migrate a WordPress site to the Jamstack' # push the changes to your repo git push origin master
Next, we can use the Netlify CLI to deploy our site.
To start, we need to install the CLI globally. Then we can run
ntl init to connect our site’s repo to Netlify, which means any time we push code changes the site will redeploy.
# install the Netlify CLI on your computer npm install -g netlify-cli # set up your site for automatic deployment for new code commits ntl init
Follow the prompts to finish initializing the site.
NOTE: if this is your first time using the Netlify CLI, you’ll be asked to log in. Follow the directions in the CLI to get logged in, then run
ntl initagain.
Once the site is set up, we can visit the Netlify dashboard and we’ll see our newly deployed site.
Once the site finishes building, which should only take a minute or so, the site is fully live and on the internet!
The site we built in this tutorial is live at.
Automatically trigger Netlify deploys whenever changes are made in WordPress
Netlify sites automatically rebuild whenever changes are pushed to our code, but we also want the site to rebuild when changes are made to our WordPress content.
To do that, we need to install a plugin called JAMstack Deployments on our WordPress site. Head to the Plugins section of our WordPress admin, then click “Add New” and search for “jamstack”. JAMstack Deployments will be the first option.
Once the plugin is installed, go to the Settings menu, then choose the new Deployments section. To fill this section out, we need to create a Build Hook in our Netlify settings.
Head to the Netlify dashboard, then click Settings. In the side menu of the Settings page, click “Build & deploy”, then scroll down to the “Build hooks” section and click “Add build hook”.
Once you’ve created the hook, copy the URL and paste it into the WordPress Deployment settings field called “Build Hook URL”.
Next, go to the Settings page of your Netlify dashboard and scroll down to the “Status badges” section. The badge has two URLs: the first is the actual image for the badge, and the second is a link to your site’s Deploys page.
Copy and paste each URL into the respective Deployments settings fields.
Finally, check boxes for the types of updates that should trigger a rebuild on Netlify. If you’re not sure which ones you need, start with posts, pages, and navigation menu items — you can always adjust these settings later on.
Save these settings, then make an edit to a page in the WordPress admin section.
If you check the Deploys page of your Netlify dashboard, we’ll see that the site is rebuilding!
And that’s it! We now have a Jamstack frontend for our WordPress site that is fully powered by WordPress data and automatically rebuilds whenever the code or content changes. 🎉
What to do next
At this point, we’ve covered all the steps required to migrate a WordPress site to the Jamstack. We can take things much further, but this is enough to get up and running.
If you have specific questions about how to migrate your own WordPress sites to the Jamstack, I’d love to hear about them.

One problem I ran into using haskelldb (both the old and new
versions), is how do you deal with auto_increment fields?
Once in a fit of insanity I figured out this little hack:
sqlnull = (Expr (ConstExpr "NULL"))
newprofile = ( userid = sqlnull
, login_name = constant "jeremy.shawNULL@..."
, cryptpassword = sqlnull
, realname= constant "boing"
, groupset= constant 0
, disabledtext= constant "dis"
, mybugslink=constant (1 :: Int)
, blessgroupset= constant 0
)
But then I was immediatly faced with a second problem -- how do I find
out what the autogenerated ID is ?
So I hacked this up:
mysqlInsertNewId connection table assoc
= do mysqlPrimCommand connection sql
res <- mysqlPrimQuery connection "select LAST_INSERT_ID();"
fields <- mysqlPrimFields res
return (getVal (MysqlValue (head (head fields))))
where
sql = show (ppInsert (toInsertNew table assoc))
A hack indeed! But, at the time I had to get things working fast, so I
didn't care ;) I should point out this this hack is actually fairly
safe. Note that the insert and the select LAST_INSERT_ID() are both
done on the same connection. As long as I hold that connection open,
LAST_INSERT_ID() will return the last autogenerated ID that was
inserted on that connection, even if records have been submitted in
the meantime on other connections.
See:
I have only tried this with MySQL, so maybe its not a very portable
solution.
In any case, I am now faced with similar problems using the new
haskellDB. This time around, I thought it might be worthwhile to think
about the problem a bit longer :)

Predicting is not a terribly exact activity. If you want to know exactly what will happen tomorrow, you’ll have to wait until the day after tomorrow. And then it’s called ‘reporting’. It has the obvious downside that through a report there is little you can do to anticipate what happened yesterday. If you want to be better prepared for what is happening in the future and act upon it, you’ll have to predict and accept that predicting comes with uncertainty.
BigML has just released new features to support you in working with that uncertainty. As you explore your predictive model and navigate the various decision paths that lead to predictions, you can now see how confident we are that it is a correct prediction. At every single node we will show you:
- The number of instances that support this node
- What percentage that is from your total training data
- The distribution of all values at this node
- The actual prediction at that node
- For categorical trees, the confidence level for the prediction at the node
- For regression trees, the expected error for the prediction at the node
These last two, the “confidence level” and the “expected error” are there to help you measure how certain you can be of your prediction. Both values are based on two sources. Firstly, they take into account the distribution of the classes at this node. For instance, if ten instances pass through a node, seven ‘yes’ and three ‘no’, the prediction will be ‘yes’ but with a lower confidence than when all ten instances are a ‘yes’. Secondly, confidence takes into account the number of instances that the prediction is based upon. Uncertainty about a predicted class is higher with only 10 instances than, for instance, with 1,000 instances. So the confidence will be higher as the prediction is based on more instances.
Using these numbers, we can create “confidence intervals” around some of the statistics at each node. The idea is to give you a number that will probably underestimate the performance of your model. So our confidence number for classification trees means essentially, “BigML is fairly certain that the prediction at this node will be right at least this percentage of the time”. Similarly, the expected error for regression trees means that your average prediction error at this node will be almost certainly better than the number provided. In short, these numbers are both pessimistic estimates of the truth.
Of course, these numbers come with the usual caveats. If you train your model on, say, car sales in San Francisco and use it to to predict car sales in Alpha, Michigan, you’ve just ruined everything. Confidence and error, like the rest of your model, is only useful when your training data is “somewhat similar” to your testing data (in statistics we would say that the data must be drawn from the same distribution).
So What is ‘Confidence’?
Confidence tells us how certain the model is that it predicts the right class at a certain node. It’s a value between 0%: ‘no guarantees at all on the quality of the prediction’ and 100%: ‘prediction is absolutely certain’. The full technical definition is: “Classification confidence is the lower end of the Wilson score interval (at 95% confidence) about the probability that the node’s prediction matches the class of one of the node’s instances”. Well, let’s just remember that the higher the confidence, the better.
Let’s look at two examples from the Iris-model that predicts one of three iris species.
The prediction for this node is the species ‘iris versicolor’. 52 Instances reached this node, 48 of class ‘iris versicolor’ and four instances of class ‘iris virginica’. The confidence for this prediction is 81.82%, with both a high occurrence of the predicted class (48 out of 52) and a decent amount of instances.
This node predicts ‘iris virginica’, based on three instances. Two instances with class ‘iris virginica’ and one with ‘iris versicolor’. The confidence is only 20.76%, mainly because of the low number of instances that support this prediction, but also because the majority class here is 2/3, whereas the previous case had a stronger majority.
How About ‘Error’ for Regression Trees?
For regression trees that predict a number in stead of a class, an error is given to indicate uncertainty. When a node predicts a value with an error of 9.01, it means that the prediction is, on average, likely to be within 9.01 of the target. Keep in mind that this is an average, so while a single prediction may be more than 9.01 away from the true target, on average you are likely to do better than that.
An example of Error:
For this node, the tree predicts a value of 10.09, with an expected error of 9.01, based on 275 instances.
The expected error might not be the most useful number of you. You might have other questions like, “What’s the possible range for the target value at this node?”, or “What is the probability that a target at this node will be greater than some value?”, or even “Is my error more likely to be skewed to one side of the prediction?” To help answer those questions, the pop-up also shows you the distribution of those 275 instances. When you mouse over it, you’ll see the values in each bin of the histogram.
Confidence in Your Predictions
These features add to your insights and help you deal with the uncertainty that comes with working with predictive analytics. If you have questions or ideas for improving our services, we apreciate your feedback.
How can i get the confidence for the downloadable model e.g. in ruby?
How can i get the confidence in the executable model e.g. in ruby?
Instead of using the web version, download them model programmatically, and then reify the model locally. For example, using Python you can do something like this:
from bigml.api import BigML
from bigml.model import Model
api = BigML()
remote_model = api.get_model(‘model/52c7b3f90c0b5e6475000f07′)
local_model = Model(remote_model)
local_model.predict({}, with_confidence=True)
[u’false’, 0.61665, [[u’false’, 500], [u’true’, 268]], 768]
You’ll get the prediction, the confidence, the distribution, and the total count.
The json version of the model comes with the distribution and the confidence at each node of the tree.
Hope that helps!

Could anybody clarify me the definition of expected error? I don´t get to understand what it is.

Writing.
I posted a link to this article from the minifb google group.
hey thanks for the nice article!!
I'm struggling getting my Kid template to play nice with fbml. Could you share a bit of your old Genshi, a skeleton is all I need, I guess I'm not so handy with Kid that I understand what it's complaining about. I think I really don't get what the xml parser is doing.
I'm trying to put together an example of TurboGears and Facebook that I can share.
Thanks.
Nice work, thanks a lot!
to Mickey: I think you can easily come over it by modifying the kid template source (init.py & serialization.py), e.g. adding a new format like %fbml%.
To Stone and Will:
I did overcome my problems with Kid. Thanks, Will, for the examples. I'll be wrapping it up into something useful as a tutorial, and will put the code on GoogleCode to share.
The trick was using output='xml' in the expose decorator, and getting the name space correct in the kid file. I don't understand xml namespaces, but somehow I got the correct combinations.

The heading might be confusing - i will try to explain what I want to do:
I'm studying computer-science and trying to implement a small movie-recommender as a project for my lecture "Data-Warehousing & Data Mining". Right now I'm trying to compute the similarity of 2 users according to their movie-ratings.
class Rating(Model):
def __init__(self, userID, movieID, rating):
...
__eq__, __ne__ and __hash__
def similarity(userA, userB):
ratingsA = userA.ratings
ratingsB = userB.ratings
common_ratings = set((ratingsA, ratingsB))
[Rating(userID=1, movieID=4, rating=4.7), Rating(user=1, movie=7, rating=9.8)]
[Rating(userID=2, movieID=4, rating=2.0), Rating(user=2, movie=7, rating=6.6)]
lA = []
lB = []
for rA in ratingsA:
for rB in ratingsB:
if rA.movieID == rB.movieID:
lA.append(rA)
lB.append(rB)
sim = cos_dist(lA, lB)
Your approach is O(N^2) worst case. You can reduce the complexity to O(N log N) sorting the ratings lists:
sorted_ratingsA = sorted(ratingsA, lambda x: x.movieID) sorted_ratingsB = sorted(ratingsB, lambda x: x.movieID)
And now we can pop the items from these lists from the last one (for efficiency reasons) and use the order over the
movieID to check whether a certain id was rated by the user. Something along the lines of:
lA = [] lB = [] maxA = sorted_ratingsA.pop() maxB = sorted_ratingsB.pop() while sorted_ratingsA and sorted_ratingsB: if maxA.movieID == maxB.movieID: lA.append(maxA) lb.append(maxB) # instead of the following two pop calls you could simply # change the elif into a new if statement. maxA = sorted_ratingsA.pop() maxB = sorted_ratingsB.pop() elif maxA < maxB: maxB = sorted_ratingsB.pop() else: maxA = sorted_ratingsA.pop()
As you can see the list that contain the maximum value is popped until either an equal id is found or until the id goes below, in that case you start popping from the other list. The fact the the lists are in ascending order means you find all matches in O(N log N).
It is essential to use
pop() because popping the end of a
list takes amortized O(1) time, while using something like
pop(0) would cost O(N) for each pop on average and would reintroduce an O(N^2) factor.
An alternative approach is to simply use hashing, and this should get you on average time O(N). You first create two maps from
movieID to ratings, and then intersect the maps:
mapA = {x.movieId: x for x in ratingsA} mapB = {x.movieId: x for x in ratingsB} common_keys = mapA.keys() & mapB.keys() lA = [mapA[k] for k in common_keys] lB = [mapB[k] for k in common_keys]
If you are using python<3.x replace
keys() with
viewkeys().
Note: even if this solution uses hashing, the order of
lA and
lB matches because iteration order over a
set changes only if the set is modified, so the two iterations above retrieve the corresponding ratings. However the order of the ratings itself is not defined (so you don't know the order in which the
movieID will appear, but you know that it will match between
lA and
lB).
You didn't mention SQL in your question, in any case if these objects are in an SQL database it's better to just let the database do the search for you.
You probably have a
rankings table with various fields and you want to do:
SELECT * FROM rankings JOIN rankings AS rankings2 ON rankings.movieID = rankings2.movieID | https://codedump.io/share/9kToVkwGRezr/1/efficient-way-to-to-find-objects-with-common-attributes-in-2-python-lists | CC-MAIN-2017-22 | refinedweb | 576 | 65.12 |

That's not a very useful post. In the real world you won't be implementing a hello world application. You'll have to integrate with Spring/CDI/EJB/MDB/…. This post does nothing to explain "websocket beans" or their API. Are they EJBs? Are they CDI beans? What's their lifecycle? How can they reference and be referenced by other beans? Is streaming supported? Can they be used without component scanning (which is slow)?
I wouldn't have said anything if there was at least a work in progress spec that could be downloaded.
very interesting stuff.
First question, what about security? What is to prevent millions of browsers from being turned into zombie spambots?
Next question, What about server load? as I am sure you are well aware, servers are limited in the number of simultaneous connections they can maintain. If every web session started keeping a connection open, that would probably reduce effective server capacity by a factor of a hundred to a thousand.
What about browser compatibility? I see Mozilla on that list, no surprise there, Mozilla is always at the leading edge of innovation, but what about sleepy giant Microsoft? have they expressed an intent to get on-board with this? they just recently finally got around to deciding to support SVG. What about Mac, or Opera? If the cross-browser support isn't there, this just becomes yet another major compatibility headache for developers. Or are you saying that your library will make this work with any browser that supports Java?
What about performance? The Java Media Player was very cool, but unfortunately was way too slow to be usable, thus it's adoption has been near to zero. Is this going to be another one of those... brilliant but failed attempts? JavaScript itself is quite slow too.
With regard to the name, WebSocket is singular; is only one connection per web page allowed? If you can have multiple connections then wouldn't it make more sense for the name to be plural? On second thought, we are actually talking about two different names... There is the name of the function itself which ought to be singular because it is creating a single connection per invocation, but then there is the name that is used when referring to the API in general, which it seems to me ought to be plural as long as more than one connection is possible within a web page. Just my two cents...
Have a great day!
This is very interesting article. Thanks a lot for posting..
I like the simplicity of the development model using anotation.
But I have a question :
Can we use a @WebsocketMessage method of a Websocket endpoint in a MDB to publish JMS messages to client browsers?
"codeslinger compsalot", if you need information on Websocket support see the stackoverflow article. I think it's a pretty complete and up to date article.
Is there any change in the Java class as per the newest spec (say build 70). Somehow I get the following in the error console.

Read C++ for the Impatient and more than 24,000 other books and videos on Safari Books Online. Start a free trial today.
It's not uncommon to use C++ for text processing; for example, reading a file containing HTML code and writing another file containing the same code in a different HTML format. Could you do that by reading and analyzing one character at a time? Of course. But such tasks can require a lot of work. The new C++11 specification adds the capabilities of regular expressions (regex) to the Standard library, which can make your life easier.
Simply put, a regular expression is a text pattern. It's a boon to text processing, though, enabling you to do a great deal with just a few lines of C++ code. A regular expression grammar is a language unto itself—but a language that's relatively simple and easily learned. Utilizing this grammar, you specify patterns for matching and (optionally) replacing. Then, at runtime, the program builds a regular-expression state machine that does most of the work for you.
You don't really need to know how it works. In fact, you only need to know a few things:
- The regular expression grammar used by the C++11 regex library functions
- The relevant C++11 functions and how to call them
The first part of this article focuses on the default regex grammar used in C++11: the ECMAScript grammar. You'll generally want to use ECMAScript, because it provides powerful capabilities while being easy to use. For simplicity, I'll focus on this grammar.
Elementary Range Specification
One of the simplest things to do with regular expression grammar is specify a range. For example, you can specify a range matching a single lowercase letter in English:
[a-z]
This regular expression matches exactly one such character. Alternatively, you can specify a range that matches a single lowercase letter, uppercase letter, or digit:
[a-zA-Z0-9]
If this is your first look at a regular expression, you might well ask: How exactly are the different characters used here? The first thing to understand is that the characters a, z, A, Z, 0, and 9 are intended literally; they mean what they are. For example, suppose you used the following regular expression (which is perfectly legal, by the way):
cat2
This expression would match an exact occurrence of cat2 and nothing else.
The brackets ([ ]) have a special meaning. Like most special characters, they always have this special meaning unless they're "escaped" by a backslash (\). Let's say you wanted to match a character that can be either an open bracket or a digit. You'd use this regular expression:
[\[0-9]
The backslash (\) causes the second occurrence of the open bracket ([) to lose its special meaning.
But remember that we're dealing with the C++ programming language. The regular expression engine needs to be fed a single backslash in this case, but C++ string notation also uses the backslash as an escape character. Confused yet? The upshot is that (unless you're working with raw literals), it's necessary to use two backslashes in the C++ code itself. This is one of the most important things to understand in using C++ regular expressions. In a program, the string would be coded as follows:
char regex_str[] = "[\\[0-9]";
Specifying Repeated Patterns
Let's return to the initial example: matching a lowercase letter. The following pattern represents a single occurrence of a lowercase letter:
[a-z]
Typically we'd want to match a series of such characters. To do that, the range is followed by an asterisk (*, meaning "zero or more") or a plus sign (+, meaning "one or more"). Appending a plus sign—another special character, by the way—says, "Match an occurrence of one or more":
[a-z]+
Already we've come to a point of confusion in the documentation of most regular expressions. You might reasonably think that the plus sign means "Match one or more of the preceding expressions in addition to matching what the expression [a-z] does, which is to match one lowercase letter." Logically, then, you might think that the overall expression [a-z]+ matches two or more letters. But that's not how it works. The plus sign isn't grammatically separate from the expression it follows; rather, it's an expression modifier, changing the meaning of the expression to which it applies. It doesn't mean, "Match the expression one or more times in addition to matching it once."
Therefore, the overall expression [a-z]+ matches any of the following examples:
a x ab cat aardvark
But it doesn't match an empty string. The following expression matches an empty string—as well as longer strings—because the asterisk (*) means, "Match the preceding expression zero or more times":
[a-z]*
At this point, you might wonder what gets modified. The answer is that the plus sign and asterisk operators apply to the character immediately preceding, if that would be grammatically sensible, but they can also apply to an immediately preceding range or a group.
Unsurprisingly, parentheses are used to specify a group. Consider the following expression:
Abc+
This expression matches any of the following target strings:
Abc Abcc Abccc
Now consider this expression:
(Abc)+
Enclosed in parentheses, Abc is a group, so this regular expression matches any of the following target strings:
Abc AbcAbc AbcAbcAbc
Before we leave this subject, let's consider another question. Just how many characters are actually matched? The general answer is that, for the most part, the regular expression engine matches as many characters as it can. But consider this innocent-looking expression:
c[a-z]*t
This expression says, "Match the letter c, and then match any number of lowercase letters, and then finally match t." Does this expression match the word cat? Yes, but there's an issue. Once a character is matched, it's not matched again. The letter c, for example, is matched just once. The regex engine then matches as many other lowercase letters as it can. If we take this rule as an absolute, it would match the word at, wouldn't it? But the letter t, already being matched, can't be matched again. The regex engine would then try to match t again—and fail.
As you might suppose, this isn't really how it works. These are the general rules:
- The regular expression engine is flexible. It will attempt to match the complete pattern as often as it can, even if this means that certain sub-expressions (in this example, [a-z]*) actually match fewer characters than possible.
- Otherwise, the regular expression engine will match as many characters in the target string as it can.
The important thing to remember is that an expression such as c[a-z]*t will do exactly what you want. It will match cat, catapult, cut, and clot, among other strings.
Incidentally, if you want the pattern to stop at the first letter t, use this:
c[a-su-z]*t
A Practical Example: MS-DOS File Names
Now we know almost enough to consider a practical example: finding all the file names that appear in a text file. In the Windows and Mac OS X operating systems, file names are flexible, so let's limit ourselves to something close to MS-DOS file names. Let's look for patterns of text that contain the following items, in the order shown:
- Match an underscore (_) or an uppercase or lowercase letter.
- Match any number of underscore, letter, or digit characters.
- Match a literal dot (.).
- Again, match any number of underscore, letter, or digit characters.
Before formulating the necessary regular expression, we need one more piece of information: how to specify a dot (.), also known as a period or full stop. The dot has a special meaning to regular expression grammar. Therefore, to specify a literal dot, it must be "escaped":
\.
But remember that in a standard C++ string, the backslash also is an escape character; therefore it must be applied twice in C++ code:
string s = "\\."; // Pattern to match a dot (.)
By the way, the dot matches any single character other than a newline (return). So the following regular expression, which may be the most general of all, matches any number of characters, whether printable or whitespace:
.*
It may seem like there are quite a few special characters and therefore a lot of things you need to remember to "escape" (that is, precede with a backslash if you want to represent their literal value). Actually, there aren't many. Here's the set you need to remember:
[ ] ( ) \ . * + ^ ? | { } $
These are mostly the punctuation characters on the top row of your keyboard, other than @, #, and &.
The hyphen or minus sign (-) is a special case. It helps to specify a range, but only if it appears within brackets ([ ]), and between two other characters within the range. Otherwise, the minus sign is a literal character and doesn't need to be escaped. By the way, most special characters lose their special meaning inside brackets, except for the brackets themselves. Therefore, you can specify a character that's either a plus or minus sign this way:
[+-]
Now, back to the problem of specifying a file name in MS-DOS style. The regular expression needed is as follows:
[a-zA-Z_][a-zA-Z_0-9]*\.[a-zA-Z0-9]+
To specify this text in a C++ literal string, remember that the backslash must be doubled:
char regex_str[] = "[a-zA-Z_][a-zA-Z_0-9]*\\.[a-zA-Z0-9]+";
Here's the translation: "Match a letter or an underscore. Then match zero or more characters, in which each may be a digit, a letter, or an underscore. Then match a literal dot (.). Finally, match one or more characters, in which each may be a digit or a letter."
If you want to impose the really old MS-DOS convention that permits file extensions of one to three characters, use the {n, m} syntax, which controls how many times the pattern immediately preceding will be repeated:
char regex_str[] = "[a-zA-Z_][a-zA-Z_0-9]*\\.[a-zA-Z0-9]{1,3}";
Using the C++11 regex_search Function
If you already understood the basics of regular expression grammar and waited through the preceding discussion to understand how the C++11 functions work, thank you for your patience. (Or, if you skipped ahead and found the right section, congratulations!)
The first step in using a regular expression in C++ code is to create a regular expression object. Such an object is a rarity in the world of C++: It's compiled at runtime. As a result, regular expressions in C++ are very flexible. You can put strings together dynamically to create entirely new regular expressions at runtime. You can also let the user specify regular expressions.
However, because compiling a regular expression at runtime incurs a performance cost, you should limit your creation of regular expression objects, reusing them as needed. Another problem: Most regular-expression errors aren't detected until runtime, at which point an exception is thrown, so you may need to use exception handling.
Before creating a regular expression object, you need to include some declarations. All class names in the regular expression library are part of the std namespace:
#include <regex> using namespace std;
Then you can create a regular expression object from a C-string (const char * type) or the STL string class. For example:
string regex_str = "[a-zA-Z_][a-zA-Z_0-9]*\\.[a-zA-Z0-9]+"; regex reg1(regex_str);
You can also specify the regex object more directly:
regex reg1("[a-zA-Z_][a-zA-Z_0-9]*\\.[a-zA-Z0-9]+");
The regex constructor also supports an optional flags field. The most useful of these by far is the regex_constants::icase flag, which causes case to be ignored; in other words, uppercase and lowercase letters are treated interchangeably. By setting this flag, we can write a more succinct pattern string:
string regex_str = "[a-z_][a-z_0-9]*\\.[a-z0-9]+"; regex reg1(regex_str, regex_constants::icase);
Now that we have a regex object, we can pass it to some useful C++ functions, such as regex_search. This function returns true if the target string contains one or more instances of the pattern specified in the regular expression object (reg1 in this case). For example, the following expression would return true (1) because it finds the substring "readme.txt" within the target string "Print readme.txt" and because "readme.txt" matches the pattern specified in reg1:
regex_search("Print readme.txt", reg1)
Now consider a more practical application. Let's say you've opened a text file represented by the object txt_fil. You could search for occurrences of file names throughout the text file in this way:
string s; int lineno = 0; while(!txt_fil.eof()) { ++lineno; getline(txt_fil, s); if (regex_search(s, reg1)) { cout << "File name found @ line "; cout << lineno << endl; } }
Iterative Searching (Search All)
As useful as the preceding code fragment is, you'd probably want your application to do more. The regex_search function returns true when it finds the first substring that matches the regular expression pattern. But more often, you'd want to find the occurrence of every substring—not just the first—that matches the pattern.
The regex_iterator class makes writing such code easy. Note that there are at least two such classes (more, if you consider wide character strings):
- regex_iterator iterates through a C-string (type const char *).
- sregex_iterator iterates through an object of the STL string class. (Notice that this function name begins with an s, unlike the other function name!)
The STL string class offers many advantages over the old C-string type, so I'll stick with sregex_iterator. Here's how you prepare an sregex_iterator object for use. In this example, we'll use a string object called str and initialize it:
string str = "File names are readme.txt and my.cmd."; sregex_iterator it(str.begin(), str.end(), reg1); sregex_iterator it_end;
Here the sregex_iterator class is used to create iterators, a central concept throughout most of the STL (but might be new to you). Basically, an iterator has many features in common with a pointer, but is more sophisticated. You can increment an iterator and dereference it, just like a pointer. You can also compare it to an off-the-edge ending condition.
The following statement creates an iterator that finds substrings from the beginning of the target string to the end of that string:
sregex_iterator it(str.begin(), str.end(), reg1);
As soon as it's created, the iterator (it) points to the first substring found (if any), applying the regex pattern in reg1.
The first substring can be produced by dereferencing the iterator (*it). You can then advance to the next substring by incrementing the iterator (++it). We'll apply both these operations in the while statement to follow.
What's unique about sregex_iterator and regex_iterator is that declaring such an iterator without initializing it automatically creates an ending condition. We'll test the iterator against this:
sregex_iterator it_end;
The following code does what you want: Find and print every substring that matches the pattern in the regex object reg1:
while(it != it_end) { cout << *it << endl; ++it; }
This while statement says: "Compare the current substring found to the iterator's own 'end' condition (it_end); if the iterator is at the end, we're done. If the iterator is not equal to its 'end' condition, there is still good data. In that case, print the substring found by dereferencing it (*it) and then advance to the next substring (++it)."
Now we'll get a printout of every substring. Given the value of the target string shown earlier, the output will be as follows:
readme.txt my.cmd
Summary
Given just the tools introduced in this article, you can do a great deal with regular expressions. For example, you can combine the last two major examples to find and print all the DOS-style file names in a text file, perhaps reporting line numbers. (I leave that exercise for the reader.)
But you can do much more with regular expressions. I haven't begun to discuss the powerful search-and-replace capabilities; that will be the subject of a future article. In the meantime, you can get started using the regular expression library as a powerful way to search string data and text files. | http://www.informit.com/articles/article.aspx?p=2079020 | CC-MAIN-2017-30 | refinedweb | 2,744 | 62.27 |

How do I convert the bytes value back to string? I mean, using the "batteries" instead of doing it manually. And I'd like it to be OK with Python 3.py
You need to decode the bytes object to produce a string:

Ionic 5 and Electron Split Pane Example for Large Screens and Desktop
The Ionoc Split Pane allows Ionic 5 developers to build user interfaces with two split views for devices with large screens such as tablets or Desktop.
The Ionic team is working to make Ionic a framework for building user interfaces for Desktop environments and not just tablets and mobile phones by adding the Split Pane which is a very requested UI component on Desktop apps.
Ionic 5 for Desktop Apps?
If you are already familiar with Ionic 5 but you have never used it for building user interfaces for Desktop apps you may be wondering, Isn't Ionic 5 a hybrid mobile framework,so how can we use it for Desktop apps?
Yes, Ionic 5 is a hybrid mobile framework based on Angular. It is actually a bunch of UI components built using HTML ,CSS and JavaScript on top of Apache Cordova which is really the actual container that does the heavy job of interfacing with mobile device native features and allow you to actually build a mobile app with web technologies.
So now how can you build Desktop apps with Ionic 5?
Just like Cordova, there is another great container but this time for Desktop environments (Windows ,Linux and MAC) which allows you to wrap JavaScript apps into a native like Desktop application .The project is Electron ,built by GitHub .
There are many other projects similar to Electron, the most popular is NW.js by Intel which follows another approach but allows you also to build cross platform Desktop apps with web technologies .
You can use either Electron or nw.js to wrap your Ionic 5 app into a Desktop application. For the sake of this tutorial, I'm going to use Electron to show how to build a Desktop app with Ionic 5 and the Split Pane component
Getting Electron
We need to create an Electron app so we are going to use Github quick start project to quickly scaffold a new app.
Open your terminal/command prompt and execute:
git clone electron-ionic-starter cd electron-ionic-starter npm install npm start
You will be presented with a blank Electron project based on Electron , next we need to integrate with Ionic 5. You don't need to do any complex configuration. You just need to install Ionic. Scaffold your Ionic 5 app, build it and then point Electron to the location of Ionic 5 web files.
Installing Ionic 5
Now we proceed to install Ionic 5. You don't need to install Cordova or any SDKs (For Android or iOS), because what we need is the UI components of Ionic 5 which are just Angular + CSS + HTML, since we are using Ionic 5 as a UI interface library for our Electron Desktop app.
So go ahead and install Ionic CLI using your terminal or command prompt:
npm install -g ionic
Creating an Ionic 5/Angular Project
Next, let's use the Ionic CLI 5 to scaffold a new blank Ionic 5 app inside our Electron app folder:
ionic start blank app -
We named our Ionic 5 project 'app'. Deel free to change to a more elegant name.
Integrating Ionic 5 with Electron
Now let's hook the two apps.
Open your Electron project
main.js file then look for the create window function:
mainWindow = new BrowserWindow({width: 800, height: 600}) // and load the index.html of the app. mainWindow.loadURL(url.format({ pathname: path.join(__dirname, 'app/www/index.html'), protocol: 'file:', slashes: true }))
After building (ionic serve) your Ionic 5 project. The App files will live under the
www folder.
So now before we continue we need to execute:
ionic serve
Inside our Ionic 5 project
Next, run our Electron app using:
npm start
You should see your Ionic 5 app with default template running inside Electron.
Adding the Ionic 5 Splite Pane
Open
src/pages/home/home.html file, delete everything and copy this code which adds a split pane with a menu at left:
<ion-split-pane> <!-- our side menu --> <ion-menu [content]="content"> <ion-header> <ion-toolbar> <ion-title>Menu</ion-title> </ion-toolbar> </ion-header> <ion-content> <ion-list> <ion-item (click)="openMain()" >Main</ion-item> <ion-item (click)="openAbout()">About</ion-item> </ion-list> </ion-content> </ion-menu> <!-- the main content --> <ion-nav [root]="rootPage" main #content></ion-nav> </ion-split-pane>
So we have added an
ion-split-pane with an
ion-menu which creates a menu at left and
ion-nav at right. Next, we will add code to change the content of
ion-nav when we click buttons on the menu.
You should pay attention to some details on the
ion-nav and
ion-menu components which are:
- root, which is binded to rootPage variable that defines the page that will be presented
- main, you should add this attribute to tell ion-split-pane where the main content lives
- #content, which specifies the target of menu actions
In the
src/pages/home.ts file, we should initialize the
rootPage variable with an initial value (a page). So first we need to generate new pages using:
ionic g page main ionic g page about
Then open the
src/app/app.module.ts file and make sure to import and add any page you have created to module
declarations and
entryComponents lists:
import { NgModule, ErrorHandler } from '@angular/core'; import { IonicApp, IonicModule, IonicErrorHandler } from 'ionic-angular'; import { MyApp } from './app.component'; import { HomePage } from '../pages/home/home'; import { MainPage } from '../pages/main/main'; import { AboutPage } from '../pages/about/about'; @NgModule({ declarations: [ MyApp, HomePage, MainPage, AboutPage ], imports: [ IonicModule.forRoot(MyApp) ], bootstrap: [IonicApp], entryComponents: [ MyApp, HomePage, MainPage, AboutPage ], providers: [{provide: ErrorHandler, useClass: IonicErrorHandler}] }) export class AppModule {}
Next open the
src/pages/home/home.ts file and copy the following code:
import { Component } from '@angular/core'; import { NavController } from 'ionic-angular'; import { MainPage } from '../main/main'; import { AboutPage } from '../about/about'; @Component({ selector: 'page-home', templateUrl: 'home.html' }) export class HomePage { rootPage :any = MainPage ; constructor(public navCtrl: NavController) { } openMain(){ this.rootPage = MainPage ; } openAbout(){ this.rootPage = AboutPage ; } }
You can now build your app using:
ionic serve
And then run electron using:
npm start
You can see the code accompanying this tutorial on GitHub

Rowan University Mechatronics Project. Wireless Car/Xbee Series 2 Section and Xbee Multiple Potentiometer Control
When choosing xbees, you must decide between series 1 and series 2. Series 1 xbees use point to point communication. This makes programming them simple since a series 1 xbee can only talk to one other series 1 xbee and not more then one. The series 2 xbee is a much more versatile tool. It can be used within a network of countless xbees all be controlled by one main xbee called the coordinator. The series 2 xbee pays for it’s versatility by being more complicated to code.
The coordinator has the ability to send signals to the other xbees. It can also receive messages from the router. As the main xbee, its job is also setting up the wireless network. The next xbee mode is the router. The router has the ability to receive messages from the coordinator and transmit them to the end device or back to the coordinator. The final xbee mode is the end device. The end device can receive messages but cannot send back a signal. Its advantage is that when not in use the end device will turn itself off until it receives the next signal in order to save energy.
For this project, an end device was not used. For some reason, the xbee network did not respond well to an end device so a router and coordinator were used instead.
This youtube link is one of five and is very informative for beginners. I would suggest only watching the first two lessons and then trying them out. Once those lessons are understood, the next three will be much easier to follow. I suggest PRACTICE, PRACTICE, PRACTICE.
Step 1:
For this project, the coordinator was used as the device that received the signal and the router was the device used to send the signal. The reasoning behind this was that the coordinator created the network so be making it the receiving end, it had less work which would increase the speed of the network. This tip was given on one of the lessons and it seemed to work well.
When programming the xbee there are two main methods I used. One was using the xbee dongle. The next method was using the xbee shield while attached to the Arduino. The first method makes reseting the xbee, something you may need to do much simpler but the other method makes setting up and testing the system using the Arduinos much simpler and faster.
The program you will need is called XCTU. I used the mac version and I will be posting pictures of the process. The windows version has a different interface but the data that must be changed is the same so the process should be repeatable on either with a little exploring into the program.
XCTU Progam
link to the download site
Step 2: Materials
1) XBees-There are many different types of xbees and many different websites that sell them at differing prices such as adafruit or digikey. This is a simple series 2 xbee. Another common one is the xbee pro. The difference between the two is that the xbee pro has a greater range....
2) USB Dongle-This is one method for connecting your xbee to the computer...
3) Arduino Uno or Mega-This micro controller is the primary means of controlling the xbee...
4) Xbee/Arduino Shield-
Avoid series 1- it is faulty, can contain shorts that could destroy the xbee
Series 2 and series 3 shield normally work well, this is the shield I used, a series 3.
I bought my series 3 xbee shield on eBay and it works fantastically
Step 3: Initial Step With Arduino
Upload this code to your arduino if you are using the arduino and the shield with the xbee on it to program your xbee.
MAKE SURE YOUR SHIELD IS SWITCHED TO USB MODE, NOT MICRO/XBEE MODE.
If you are using the dongle, ignore this step.
Step 4: XCTU Program
Once your on the XCTU program this should be what you see.
Step 5: Finding the Xbee
On the top left corner of the xctu program, select the icon with the magnifine glass.
This will open up the popup menu containing serial ports.
Select a usb port and click next.
The next popup is the search criteria, most xbees use a 9600 baud rate so normally only select that one. Keep everything else the same.
Click finish.
Your xbee should come up, in this case we see my coordinator come up as it has a C on it's icon.
Click add selected device.
Step 6:
Your newly uploaded xbee should appear on the left of your screen in the side bar.
Click on it and all the xbee's setting will come up.
Step 7: Updating or Uploading Your Firmware
This button will allow you yo change you xbees settings, coordinator, router, or end device.
USE AT MODE. NOT API, unless you understand how to send code packages.
Step 8: Repair
If for some you attempted to find you xbee, the usb port comes up, but the xbee does not, do not despair. The wrench picture displayed above could be helpful. Select it, i drop down menu will appear. Click repair and select which settings you want your xbee to have, I always chose router, at version. Hopefully this will allow you to once again search for your xbee and find it this time.
Step 9: Coordinator Programming
For the beginner, the only things you must change are Pan ID , Scan Channels, DH and DL. Set them as they are in the picture.
The Pan ID acts as an address,
The Pan ID's must be the same.
The DH and DL act as high and low frequencies for the coordinator to search.
Step 10: Router/End Device Programming
As with the coordinator, copy the Pan ID , Scan Channels, DH and DL into your program.
The Pan ID's must be the same.
Set your DH and DL both to 0, this falls within the coordinators search range.
Step 11: Xbees Talking With Each Other
This step is only useful if you can connect both xbees at the same time. This can be done with another computer or the same computer. I had mine on the same computer.
Once all your settings have been finished, go to the top right corner and select the TV icon.
Click the plug icon for both xbees. It will plug in and turn green.
Try typping stuff, anything. It should come up blue.
Click to the other xbee, the message should appear red. If it does, your xbees are talking and ready for transmission, if not return to settings and make sure everything is correct.
If you are using the router, you can type back to the coordinator and it should also go though.
Step 12: Finally
You're xbees are now ready.
Put them on the shield and then the arduino if they are not already.
Make sure the shield is switched to USB mode and program your arduinos.
Keep track of which one is the coordinator and which aren't. This will make things simpler.
These links will provide other helpful tutorials
This Code will allow you to wirelessly blink the led on you arduino
Coordinator:
void setup()
{ Serial.begin(9600); }
void loop() {
Serial.print('H');
delay(1000);
Serial.print('L');
delay(1000);
}
Router:
int num=0;
const int ledPin = 13;
// the pin that the LED is attached to int incomingByte;
// a variable to read incoming serial data into int fs );
//turn light on
}
// if it's an L (ASCII 76) turn off the LED:
else if (incomingByte == 'L') {
digitalWrite(ledPin, LOW);
//turn light off
}
}
}
Step 13: Multiple Potentiometers
After searching online, I found a library for arduino that will allow you to send multiple potentiometer values from 1 xbee/arduino combo to another. It is called the EasyTransfer Library....
An example of it being used is discussed in this forum
I have already tried it and have been able to control 3 potentiometers with both xbees in AT mode.
Below is the code I used for transmitting 3 potentiometer values wirelessly. I was able to make it using code from the second website listed on this page.
//Sender
#include <EasyTransfer.h>
EasyTransfer ET;
int potpin1 = A0;
int potpin2 = A1;
int potpin3 = A2;
struct SEND_DATA_STRUCTURE{
int servo1val;
int servo2val;
int servo3val; };
SEND_DATA_STRUCTURE txdata;
void setup(){
Serial.begin(9600);
ET.begin(details(txdata), &Serial);
pinMode(potpin1, INPUT);
pinMode(potpin2, INPUT);
pinMode(potpin3, INPUT);
}
void loop(){
txdata.servo1val = analogRead(potpin1);
txdata.servo2val = analogRead(potpin2);
txdata.servo3val = analogRead(potpin3);
ET.sendData();
delay(500);
}
This section receives the data from the potentiometers. For my own purposes, I wanted to run a test and have my Arduino print the values sent by three potentiometer.
//Reciever
#include <Servo.h>
#include <EasyTransfer.h>
EasyTransfer ET;
Servo myservo1;
Servo myservo2;
Servo myservo3;
int val1,val2,val3;
struct RECEIVE_DATA_STRUCTURE{
int servo1val;
int servo2val;
int servo3val;
};
RECEIVE_DATA_STRUCTURE txdata;
void setup(){
Serial.begin(9600);
ET.begin(details(txdata), &Serial);
myservo1.attach(9);
myservo2.attach(10);
myservo2.attach(12); }
void loop(){
if(ET.receiveData()){
val1=map(txdata.servo1val, 0, 1023, 0, 179);
val2=map(txdata.servo2val, 0, 1023, 0, 179);
val3=map(txdata.servo3val, 0, 1023, 0, 179);
Serial.println(val1);
Serial.println(val2);
Serial.println(val3);
// myservo1.write(val1);
//myservo2.write(val2);
}

Here we will learn how to create first c# hello world program in visual studio with examples, create first console application using c# programming language in visual studio with examples.
By using Visual Studio, we can easily create a Hello World Program or Console Application in C# programming language based on our requirements.
In previous chapter, we explained how to Download and Install Visual Studio on Windows Machine. In case, if you are not installed a visual studio, then follow the instructions to install visual studio otherwise open your visual studio.
To create a new application in visual studio, go to Menu bar, select File à New à select a Project like as shown below.
Once you click on Project, a new popup will open in that select Visual C# from the left pane and choose Console App. In the Name section give any name for your project and select appropriate Location path to save your project files and click OK like as shown below.
Once we click on OK button, a new console application will be created like as shown below. In case Program.cs file not opened in your code editor, open the Solution Explorer menu in right side and open your Program.cs file code by double clicking on it.
If you observe above image, by default the application contains a Main() method because the console applications in c# programming language will always starts from the Main() method of program class.
Now replace your Program.cs file code like as shown below to display “Hello World” message.
using System;
namespace HelloWorld
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Hello World!");
Console.WriteLine("Press Any Key to Exit.");
Console.ReadLine();
}
}
}
If you observe above code, we used a lot of parameters to implement “Hello World” program in c#. In next section, we will learn all the parameters in detailed manner.
Following diagram will illustrate the type of parameters which we used in our c# program in detailed manner.
Now we will go through each step of our c# program and learn each parameter in detailed manner.
using System;
Here,
using System is the .NET Framework library namespaces and we used
using keyword to import
system namespace to use existing class methods such WriteLine(), ReadLine(), etc. By default the .NET Framework provides a lot of namespaces to make the application implementation easily.
The namespace is a collection of classes and classes are the collection of objects and methods.
namespace HelloWorld
Here,
namespace HelloWorld is the main namespace of our application and by default our application classes will be a part of it.
class Program
Here,
class Program is used to define a class (Program) in namespace (Helloworld). The class (Program) will contain all the variables, methods, etc. and we can define more than one class in same namespace based on our requirements.
static void Main(string[] args)
Here,
static void Main(string[] args) is used to define a method in our class (Program).
statictells us that, the main method can be accessible without instantiating the class (Program).
voidtells us that, what this method should return.
argsand it is useful to send command line arguments as a text strings for our main method.
Console.WriteLine() / ReadLine()
Here,
Console.WriteLine() and
Console.ReadLine() methods are used to write a text to console and read the input from console.
The
Console is a class of .NET Framework namespace
System and WriteLine() and ReadLine() are the methods of
Console class.
To see the output of our Hello World C# Program, we need to compile and run the application by pressing either Ctrl + F5 or click on Start option in the menu bar like as shown below.
Once we click on Start option or Ctrl + F5, our program will get compiled and show the result like as shown below.
This is how we can create and execute the applications in c# programming language using visual studio based on our requirements. | https://www.tutlane.com/tutorial/csharp/csharp-hello-world-program-example | CC-MAIN-2018-26 | refinedweb | 658 | 64 |
Note
There is a French translation of an earlier revision of this HOWTO, available at urllib2 - Le Manuel manquant..
The simplest way to use urllib.request is as follows:
import urllib.request response = urllib.request.urlopen('') html = response.read()
If you wish to retrieve a resource via URL and store it in a temporary location, you can do so via the urlretrieve() function:
import urllib.request local_filename, headers = urllib.request.urlretrieve('') html = open(local_filename)
Many uses of urllib will be that simple (note that instead of an ‘http:’ URL we could have used an URL starting with ‘ftp:’, ‘file:’,('') response = urllib.request.urlopen(req).
Sometimes you want to send data to a URL (often the URL will refer to a CGI (Common Gateway Interface) script [1]('utf-8') # data should be bytes req = urllib.request.Request(url, data) response = urllib.request.urlopen(req) the_page = response.read()
Note that other encodings are sometimes required (e.g. for file upload from HTML forms - see HTML Specification, Form Submission for more details).
If you do not pass the data argument, urllib uses a GET request. One way in which GET and POST requests differ is that POST requests often have “side-effects”: they change the state of the system in some way (for example by placing an order with the website for a hundredweight of tinned spam to be delivered to your door)..
We’ll discuss here one particular HTTP header, to illustrate how to add headers to your HTTP request.
Some websites [2] dislike being browsed by programs, or send different versions to different browsers [3] . [4]. When you create a Request object you can pass a dictionary of headers in. The following example makes the same request as above, but identifies itself as a version of Internet Explorer [5].
import urllib.parse import urllib.request url = '' user_agent = 'Mozilla/4.0 (compatible; MSIE 5.5; Windows NT)' values = {'name' : 'Michael Foord', 'location' : 'Northampton', 'language' : 'Python' } headers = { 'User-Agent' : user_agent } data = urllib.parse.urlencode(values) data = data.encode('utf-8') req = urllib.request.Request(url, data, headers) response = urllib.request.urlopen(req) the_page = response.read()
The response also has two useful methods. See the section on info and geturl which comes after we have a look at what happens when things go wrong..
Often, URLError is raised because there is no network connection (no route to the specified server), or the specified server doesn’t exist. In this case, the exception raised will have a ‘reason’ attribute, which is a tuple containing an error code and a text error message.
e.g.
>>> req = urllib.request.Request('') >>> try: urllib.request.urlopen(req) ... except urllib.error.URLError as e: ... print(e.reason) ... (4, 'getaddrinfo failed') ‘404’ (page not found), ‘403’ (request forbidden), and ‘401’ (authentication required).
See section 10 of RFC 2616 for a reference on all the HTTP error codes.
The HTTPError instance raised will have an integer ‘code’ attribute, which corresponds to the error sent by the server. ...
So if you want to be prepared for HTTPError or URLError there are two basic approaches. I prefer the second approach..
from urllib.request import Request, urlopen from urllib.error import URLError: # everything is fine ‘Content-length’, ‘Content-type’, and so on. See the Quick Reference to HTTP Headers for a useful listing of HTTP headers with brief explanations of their meaning and use. ‘realm’. The header looks like : WWW-Authenticate: SCHEME realm="REALM".
e.g.
WWW-Authenticate: Basic realm="cPanel Users"
The client should then retry the request with the appropriate name and password for the realm included as a header in the request. This is ‘basic, HTTPErrorProcessor.
top_level_url is in fact either a full URL (including the ‘http:’.
urllib will auto-detect your proxy settings and use those. This is through the ProxyHandler, which is part of the normal handler chain when a proxy setting is detected. Normally that’s a good thing, but there are occasions when it may not be helpful ) | https://wingware.com/psupport/python-manual/3.3/howto/urllib2.html | CC-MAIN-2014-10 | refinedweb | 660 | 58.89 |
Eric, > Hmm.

I think it's up to the server to either handle large requests, or for the client to break these up. The core problem here is that the kernel (and, ahem, most servers) are ignorant of the block size extension, and need to guess how to break things up. In my view the client (kernel in this case) should be breaking the trim requests up into whatever size it uses as the maximum size write requests. But then it would have to know about block sizes which are in (another) experimental extension. I've nothing against you fixing it qemu's server (after all I don't think there is anything to /prohibit/ a server working on something larger than the maximum block size), and ... > But since the kernel is the one sending the large length request, and > since you are right that this is not a denial-of-service in the amount > of data being sent in a single NBD message, ... currently there isn't actually a maximum block size advertised (that being in another experimental addition), so this is just DoS prevention, which qemu is free to do how it wishes. > I definitely agree that qemu > would be wise as a quality-of-implementation to allow the larger size, > for maximum interoperability, even if it exceeds advertised limits (that > is, when no limits are advertised, we should handle everything possible > if it is not so large as to be construed a denial-of-service, and > NBD_CMD_TRIM is not large; and when limits ARE advertised, a client that > violates limits is out of spec but we can still be liberal and respond > successfully to such a client rather than having to outright reject it). > So I think this patch is headed in the right direction. I'd agree with that. What surprises me is that a release kernel is using experimental NBD extensions; there's no guarantee these won't change. Or does fstrim work some other way?

#include <stdlib.h> int daemon(int nochdir, int noclose);
The daemon() function provides a means for applications to run in the background.
This function ensures that the process calling this function:
runs in the background
detaches from the controlling terminal
forms a new process group
is not a session group leader.
The arguments to this function are treated as boolean variables and are evaluated using negative logic.
If the nochdir argument is zero the working directory will be changed to the root directory (/); otherwise it will not be.
If the noclose argument is zero the descriptors 0, 1, and 2 (normally corresponding to standard input, output and error output, depending on the application) will be redirected to /dev/null; otherwise they will not be.
Upon successful completion, daemon() returns 0. Otherwise it returns -1 and sets errno to the values specified for fork(2), setsid(2), open(2), and dup(2).
If daemon() is called with noclose set to 0 and fails to redirect descriptors 0, 1, and 2 to /dev/null, those descriptors are not guaranteed to be the same as before the call.
The main() function of a network server could look like this:
int background; /* background flag */ /* Load and verify the configuration. */ /* Go into background. */ if (background && daemon(0, 0) < 0) err(1, "daemon"); /* Process requests here. */
See attributes(5) for descriptions of the following attributes:

Script for doing screen captures
Created a screen for doing screen captures, so I can call it while doing other test. This script uses the time to create an unique file name, so I don’t have to worry about overwriting the same file while running my test. This script is run by monkeyrunner so I used the full path when calling monkeyrunner and my script (this is a bit bias towards OS X syntax since I am testing on a Mac at the moment)
/Users/me/Android/sdk/tools/monkeyrunner -v ALL /Users/me/Android/capture_screen.py
-v ALL is for verbose logging
#!/usr/bin/env python # coding: utf-8 # Screen shot of android # Needed modules from com.android.monkeyrunner import MonkeyRunner, MonkeyDevice import time # Wait for connection device = MonkeyRunner.waitForConnection() # Use the time in seconds to help create an unique file name for the image that is captured filelocation = "/Users/jmiller/Android/Screen_Shots/" fileNamePrefix = "scrnCap" thefile = filelocation + fileNamePrefix + str(int(time.time())) + ".png" # Snap shot of the screen result = device.takeSnapshot() # Write out the results result.writeToFile(thefile,"png") –
monkeyrunner snapshot file location
Inside my script I wanted to do a snapshot and have the image stored in my local directory where I was running the script. Once again I ran into the problem, where monkeyrunner thinks every is local to the directory where located, not where it is launched from. So in the python code I need to put the full path to where I want the image stored. But that failed do to me being a silly Windows user and typing the path with back slashes “C:0001101\Android\” to make it work I need to use forward slashes like in linux/unix “C:/00001101/Android/”
So the line of code looks like this:
result.writeToFile(‘C:/00001101/Android/dashboard.png‘,’png’)
Running a monkeyrunner script with verbose logging
Found a couple annoying things, first no matter where I am running monkeyrunner from, it thinks everything is local to is, so I have to put in the complete path to my script, even though I am running from the directory where the script is
Example (my script when I run it)
C:\Android>monkeyrunner -v ALL C:\Android\SCRIPT_signin.py
The next problem is the logging “-v” there are several logging options, however the key thing to remember is that it is case sensitive (which to me lame, “all” should equal “ALL” – but it doesn’t)
Logging levels (ALL, FINEST, FINER, FINE, CONFIG, INFO, WARNING, SEVERE, OFF).
Help.py (monkeyrunner)
Not my file just a copy of what I found (file needs to be saved as help.py)
#!/usr/bin/env monkeyrun com.android.monkeyrunner import MonkeyRunner as mr
import os
import sys
supported_formats = [‘html’, ‘text’, ‘sdk-docs’]

In this Angular 8 CRUD tutorial, we will learn how to implement crud To-do Application in Angular 8. Befor get started with angular 8 crud operation. You must have installed Angular project. So let’s get start: Create Angular 8
In this tutorial Angular 8 CRUD tutorial, we will learn how to implement CRUD To-do Application in Angular 8.
Befor get started with angular 8 crud operation. You must have installed Angular project.
So let’s get start:Create Angular 8 Component
What is component?
Components are a logical piece of code for Angular JS application. We will create three component.
Type the following command to generate Angular 8 Components. We will perform create, read, update operations. So we will create three components.
To create it:
ng g component todo ng g component todoAdd ng g component todoEdit
Open
src/app/app.module.ts you will see all the three components imported and declared in
declarations section by Angular 8 itself.
Now We need to create route for the above created component. So when you navigate the route you will be see the html of your component.
To create new route open the “app-routing.module.ts” file under the “your project directory > src > app”.
Import all three above created component to the routing module. Add the below line in the top of the “app-routing.module.ts” file.
import { TodoComponent } from './todo/todo.component'; import { TodoAddComponent } from './todo-add/todo-add.component'; import { TodoEditComponent } from './todo-edit/todo-edit.component';
You will see the route variable. Changed with this
Install bootstrap 4 CSS FramworkInstall bootstrap 4 CSS Framwork
const routes: Routes = [ { path: '', component: TodoComponent, data: { title: 'List of todos' } }, { path: 'todo/add', component: TodoAddComponent, data: { title: 'Add todo' } }, { path: 'todo/edit/:id', component: TodoEditComponent, data: { title: 'Edit todo' } }, ];
Next, install the Bootstrap 4 CSS Framework using the following command.
npm install bootstrap --save
Now, add it inside the angular.json file.
"styles": [ "src/styles.css", "./node_modules/bootstrap/dist/css/bootstrap.min.css" ]
So, now we can use the Bootstrap 4 classes in our project.Configure the Angular 8 Form Validation
We will use ReactiveFormsModule for Angular 8 Form Validation.
Now, import the ReactiveFormsModule inside the app.module.ts file.

We need
HttpClientModule to access RESTful API. So before creating a service, first, Open
src/app/app.module.ts then add this import.
import { HttpClientModule } from '@angular/common/http';
Add
HttpClientModule to imports array under
@NgModule
Create Angular 8 Service for Accessing RESTful APICreate Angular 8 Service for Accessing RESTful API
imports: [ HttpClientModule ]
Generate an Angular 8 service for Accessing RESTful API by typing this command.
ng g service api
Next, open and edit
src/app/api.service.ts then add the below function.
getTodos (): Observable<Todo[]> { return this.http.get<Todo[]>(apiUrl, httpOptions) .pipe( tap(heroes => console.log('fetched todos')), catchError(this.handleError('getTodos', [])) ); } getTodo(id: number): Observable<Todo> { const url = `${apiUrl}?id=${id}`; return this.http.get<Todo>(url).pipe( tap(_ => console.log(`fetched todo id=${id}`)), catchError(this.handleError<Todo>(`getTodo id=${id}`)) ); } addTodo (todo): Observable<Todo> { return this.http.post<Todo>(`${apiUrl}/create.php`, todo, httpOptions).pipe( tap((todo: Todo) => console.log(`added todo w/ id=${todo.id}`)), catchError(this.handleError<Todo>('addTodo')) ); } updateTodo (id, todo): Observable<any> { const url = `${apiUrl}/update.php?id=${id}`; return this.http.put(url, todo, httpOptions).pipe( tap(_ => console.log(`updated todo id=${id}`)), catchError(this.handleError<any>('updateTodo')) ); } deleteTodo (id): Observable<Todo> { const url = `${apiUrl}/delete.php?id=${id}`; return this.http.delete<Todo>(url, httpOptions).pipe( tap(_ => console.log(`deleted todo id=${id}`)), catchError(this.handleError<Todo>('deletetodo')) ); } private handleError<T> (operation = 'operation', result?: T) { return (error: any): Observable<T> => { // TODO: send the error to remote logging infrastructure console.error(error); // log to console instead // Let the app keep running by returning an empty result. return of(result as T); }; }
Run the below command, will run the Angular 8 Web Application and open the Application in browser by it self

Welcome to this course "Complete Angular Crash Course: Learn Angular from Scratch and Go from.
What you'll learn
In this JavaScript Handbook tutorial, you'll learn all you need to know about JavaScript
JavaScript 😆:
What do they mean?
They are all referring to a standard, called ECMAScript.
ECMAScript is the standard upon which JavaScript is based, and it’s often abbreviated to ES.
Beside JavaScript, other languages implement(ed) ECMAScript, including:.
The current ECMAScript version is ES2018. It was released in June 2018.
Historically, JavaScript editions have been standardized during the summer, so we can expect ECMAScript 2019 to be released in summer 2019, but this is just speculation.
TC39 is the committee that evolves JavaScript.
The members of TC39 are companies involved in JavaScript and browser vendors, including Mozilla, Google, Facebook, Apple, Microsoft, Intel, PayPal, SalesForce and others.
Every standard version proposal must go through various stages, which are explained here.The:
letand
const
I’ll cover each of them in a dedicated section here in this guide. So let’s get started..
_this_scope
The
this scope with arrow functions is inherited from the context.
With regular functions,
this always refers to the nearest function, while with arrow functions this problem is removed, and you won't need to write
var that = this ever again.:
Here is an example of a generator which explains how it all works.
function *calculator(input) { var doubleThat = 2 * (yield (input / 2)) var another = yield (doubleThat) return (input * doubleThat * another) }
We initialize it with
const calc = calculator(10)
Then we start the iterator on our generator:
calc.next()
This first iteration starts the iterator. The code returns
this object:
{ done: false value: 5 }
What happens is: the code runs the function, with
input = 10as it was passed in the generator constructor. It runs until it reaches the
yield, and returns the content of
yield:
input / 2 = 5. So we get
{ done: true value: 14000 }
As the iteration is done (no more
yield keywords found), we just return
(input * doubleThat * another) which amounts to
10 * 14 * 100.
let.
Classes have a special method called
constructor which is called when a class is initialized via
new.
The parent class can be referenced using
super().
A getter for a property can be declared as
class Person { get fullName() { return `${this.firstName} ${this.lastName}` } }
Setters are written in the same way:
class Person { set age(years) { this.theAge = years } }
Before ES2015, there were at least 3 major competing module standards, which fragmented the community:
ES2015 standardized these into a common format.
Importing is done via the
import ... from ... construct:
import * from 'mymodule' import React from 'react' import { React, Component } from 'react' import React as MyLibrary from 'react'
You can write modules and export anything to other modules using the
export keyword:
export var foo = 2 export function bar() { /* ... */ } = `Hey thisstring is awesome!`
Compare how we used to do multiline strings pre-ES2015:
var str = 'One\n' + 'Two\n' + 'Three'
Functions now support default parameters:
const foo = function(index = 0, testing = true) { /* ... */ } foo()
You can expand an array, an object or a string using the spread operator
....
Let’s start with an array example. Given the following:.
In ES2015 Object Literals gained superpowers.
Instead of doing
const something = 'y' const x = { something: something }
you can do
const something = 'y' const x = { something }
A prototype can be specified with
const anObject = { y: 'y' } const x = { __proto__: anObject }
const anObject = { y: 'y', test: () => 'zoo' } const x = { __proto__: anObject, test() { return super.test() + 'x' } } x.test() //zoox
const x = { ['a' + '_' + 'b']: 'z' } x.a_b //z:') }
The exponentiation operator
** is the equivalent of
Math.pow(), but brought into the language instead of being a library function.
Math.pow(4, 2) == 4 ** 2
This feature is a nice addition for Math intensive JavaScript applications.
The
** operator is standardized across many languages including Python, Ruby, MATLAB, Lua, Perl and many others.
ECMAScript 2017, edition 8 of the ECMA-262 Standard (also commonly called ES2017 or ES8), was finalized in June 2017.
Compared to ES6, ES8 is a tiny release for JavaScript, but still it introduces very useful features:
The purpose of string padding is to add characters to a string, so it reaches a specific length.
ES2017 introduces two
String methods:
padStart() and
padEnd().
padStart(targetLength [, padString]) padEnd(targetLength [, padString])
Sample usage:
This method returns an array containing all the object own property values.
Usage:
const person = { name: 'Fred', age: 87 } Object.values(person) // ['Fred', 87]
Object.values() also works with arrays:
const people = ['Fred', 'Tony'] Object.values(people) // ['Fred', 'Tony']']]
This method returns all own (non-inherited) property descriptors of an object.
Any object in JavaScript has a set of properties, and each of these properties has a descriptor.
A descriptor is a set of attributes of a property, and it’s composed by a subset of the following:
Object.getOwnPropertyDescriptors(obj) accepts an object, and returns an object with the set of descriptors.
ES2015 gave us
Object.assign(), which copies all enumerable own properties from one or more objects, and returns a new object.
However there is a problem with that, because it does not correctly copy properties with non-default attributes.
If an object for example just has, as it was not copied over.
The same limitation goes for shallow cloning objects with Object.create().
This feature allows to have trailing commas in function declarations, and in functions calls:
const doSomething = (var1, var2,) => { //... }doSomething('test2', 'test2',)
This change will encourage developers to stop the ugly “comma at the start of the line” habit..
It’s a higher level abstraction over of their own, and syntax complexity. They were good primitives around which a better syntax could be exposed to the developers: enter async functions.
Code making use of asynchronous After I did something //after 3s) })?
ES6 introduced the concept of a rest element when working with array destructuring:
const numbers = [1, 2, 3, 4, 5] [first, second, ...others] = numbers
and spread elements:
<pre class="gk gl gm gn go jv jw cm"><span id="9561" class="hx hy ef at jp b fa jx jy r jz">const numbers = [1, 2, 3, 4, 5] const sum = (a, b, c, d, e) => a + b + c + d + e const sum = sum(...numbers)</span></pre
ES2018 introduces }
The new construct
for-await-of allows you to use an async iterable object as the loop iteration:
for await (const line of readLines(filePath)) { console.log(line) }
Since this uses
await, you can use it only inside
async functions, like a normal
await (see async/await)'))
RegExp lookbehind assertions: match a string depending on what precedes it.
This is a lookahead:aheads use the
?= symbol. They were already available.
Lookbehinds, a new feature,
('[email protected]') //✅ /^\p{ASCII}+$/u.test('ABC('🙃🙃') /.
In ES2018 a capturing group can be assigned to a name, rather than just being assigned a slot in the resulting array:
const re = /(?<year>\d{4})-(?<month>\d{2})-(?<day>\d{2})/ const result = re.exec('2015-01-02')// result.groups.year === '2015'; // result.groups.month === '01'; // result.groups.day === '02';
's’flag for regular expressions
The
s flag, short for single line, causes the
. to match new line characters as well. Without it, the dot matches regular characters but not the new line:
Coding StyleCoding Style
/hi.welcome/.test('hi\nwelcome') // false /hi.welcome/s.test('hi\nwelcome') // true.
Even if you prefer a set of styles, when working on a project you should use that project’s style.
An Open Source project on GitHub might follow a set of rules, another project you work on with a team might follow an entirely different one.

'instead of double quotes
". Double quotes are a standard in HTML attributes, so using single quotes helps remove problems when dealing with HTML strings. Use template literals when appropriate instead of variable interpolation.
Now we’ll take a deep dive into the building blocks of JavaScript: unicode, semicolons, white space, case sensitivity, comments, literals, identifiers and reserved words
JavaScript is written in Unicode. This means you can use Emojis as variable names. 😃 😧 😲 But more importantly, you can write identifiers in any language, for example Japanese or Chinese, with some rules. variable.
We define as literal, an object. It can start with a letter, the dollar sign
$ or an underscore
_, and it can contain digits. Using Unicode, a letter can be any allowed char, for example an emoji 😄.
Test test TEST _test Test1 $test
The dollar sign is commonly used to reference DOM elements.
You can’t use as identifiers any of the following words because they are reserved by the language.
VariablesVariables
break do instanceof typeof case else new var catch finally return void continue for switch while debugger function this with default if throw delete in try class enum extends super const export import implements let private public interface package protected static yield
A variable is a literal assigned to an identifier, so you can reference and use it later in the program. We’ll learn how to declare one with JavaScript. referenced as “untyped”.
A variable must be declared before you can use it. There are 3 ways to do it: using
var,
let or
const. Those 3 ways differ in how you can interact with the variable later on.
var
Until ES2015,
var was the only construct available for defining variables.
var a = 0
If you forget to add
var you will be assigning a value to an undeclared variable, and the results could into a function with the same name_seems an obscure term, just read
_let color = 'red'_as let the color be red and all has much more sense.
Defining
let outside of any function - contrary to
var - does not create a global variable.
const
Variables declared with
var or
let can be changed later on in the program, and reassigned. A.
TypesTypes
Why? Because we should always use the simplest construct available to avoid making errors down the road.
You might sometimes read that JS is untyped, but that’s incorrect. It’s true that you can assign all sorts of different types to a variable, but JavaScript has types. In particular, it provides primitive types, and object types.
Primitive types are
And two special types:
Let’s see them in detail in the next sections.
Internally, JavaScript has just one type for numbers: every number is a float.
A numeric literal is a number represented in the source code, amd depending on how it’s written, it can be an integer literal or a floating point literal.
Integers:
10 5354576767321 0xCC //hex
Floats:
3.14 .1234 5.2e4 //5.2 * 10^4 with ${something}`
JavaScript defines two reserved words for booleans: true and false. Many comparision operations
==
===
<
> (and so on) return either one or the other.
if,
while statements and other control structures use booleans to determine the flow of the program.
They don’t just accept true or false, but also accept truthy and falsy values.
Falsy values, values interpreted as false, are
0 -0 NaN undefined null '' //empty string
All the rest is considered a truthy value.
null is a special value that indicates the absence of a value.
It’s a common concept in other languages as well, can be known as
nil or
None in Python for example..
Under this category go all expressions that evaluate to a number:
1 / 2 i++ i -= 2 i * 2
Expressions that evaluate to a string:
'A ' + 'string'
Logical expressionsLogical expressions
[] //array literal {} //object literal [1,2,3] {a: 1, b: 2} {a: {b: 1}}
Logical expressions make use of logical operators and resolve to a boolean value:
a && b a || b !a
new //create an instance of a constructor super //calls the parent constructor ...obj //expression using the spread operator
object.property //reference a property (or method) of an object object[property] object['property']
new object() new a(1) new MyRectangle('name', 2, {a: 4})
function() {} function(a, b) { return a * b } (a, b) => a * b a => a * 2 () => { return 2 }
The syntax for calling a function or method
Prototypal InheritancePrototypal Inheritance
a.x(2) window.resize()
JavaScript is quite unique in the popular programming languages landscape because of its use of prototypal inheritance. Let’s find out what that means.
While most object-oriented languages use a class-based inheritance model, JavaScript is based on the prototype inheritance model.
What does this mean? const list = new Array()
The prototype is
Array.
You can verify this by checking the Object.getPrototypeOf() and the Object.prototype.isPrototypeOf() methods:
const car = {}const list = []Object.getPrototypeOf(car) === Object.prototypeObject.prototype.isPrototypeOf(car)Object.getPrototypeOf(list) === Array.prototypeArray is still the same, and you can access an object prototype in the usual way.().
Normally methods are defined on the instance, not on the class.
Static methods are executed on the class instead:
class Person { static genericHello() { return 'Hello' } }Person.genericHello() //Hello
JavaScript does not have a built-in way to define private or protected methods.
There are workarounds, but I won’t describe them here.
You can add methods prefixed with
get or
set to create a getter and setter, which are two different pieces of code that are execute:
ExceptionsExceptions
class Person { constructor(name) { this._name = name } set name(value) { this._name = value } }
When the code runs into an unexpected problem, the idiomatic JavaScript way to handle this situation is through.
JavaScript semicolons are optional. I personally like to avoid using semicolons in my code, but many people prefer them.
Semicol JavaScript parser will automatically add a semicolon when, during the parsing of the source code, it finds these particular situations:
}, closing the current block
returnstatement on its own line
breakstatement on its own line
throwstatement on its own line
continuestatement on its own line a piece of code:
(1 + 2).toString()
prints
"3".
const a = 1 const b = 2 const c = a + b (a + b).toString()
Instead, the above).
Pick some rules:
returnstatements. If you return something, add it on the same line as the return (same for
break,
throw,
continue) on multiple lines`
Not just that. You can interpolate variables using the
${} syntax:
const multilineString = `A string allow, in particular:
Let’s dive into each of these in detail.
Pre-ES6, to create a string spanned()
Template literals provide an easy way to interpolate variables and expressions into strings.
You do so by using the
${...} syntax:
const var = 'test' const string = `something ${var}` //something test
Inside the
${} you can add anything, even expressions:
const string = `something ${1 + 2 + 3}` const string2 = `something ${foo() ? 'x' : 'y' }`
Tagged templates is one feature that might sound less useful at first for you, but it’s actually used by lots of popular libraries around, like Styled Components, the GraphQL client/server library, so it’s essential to understand how it works.
In Styled Components template tags are used to define CSS strings:
const Button = styled.button` font-size: 1.5em; background-color: black; color: white; `;
In Apollo template tags are used to define a GraphQL query schema:
const query = gql` query { ... } `
The
styled.button and
gql template tags highlighted in those examples are just functions:
function gql(literals, ...expressions) { }
This function returns a string, which can be the result of any kind of computation.
literals is an array containing the template literal content tokenized by the expressions interpolations.
expressions contains all the interpolations.
If we take the example above:
const string = `something ${1 + 2 + 3}`
literals is an array with two items. The first is
something, the string until the first interpolation, and the second is an empty string, the space between the end of the first interpolation (we only have one) and the end of the string.
expressions in this case is an array with a single item,
6.
A more complex example is:
const string = `something another ${'x'} new line ${1 + 2 + 3} test`
In this case
literals is an array where the first item is:
`something another `:
JavaScript FunctionsJavaScript Functions
function interpolate(literals, ...expressions) { let string = `` for (const [i, val] of expressions.entries()) { string += literals[i] + val } string += literals[literals.length - 1] return string } as a regular function
Functions can be assigned to variables (this is called a function expression):
const dosomething = function(foo) { // do something }
Named function expressions are similar, but play nicer with the stack call trace, which is useful when an error occurs - it holds the name of the function:
const dosomething = function dosomething(foo) { // do something }
ES6/ES2015 introduced arrow functions, which are especially nice to use when working with inline functions, as parameters or callbacks:
const dosomething = foo => { //do something }
Arrow functions have an important difference from the other function definitions above, we’ll see which one later as it’s an advanced topic.
A function can have one or more parameters.
const dosomething = () => { //do something }const dosomethingElse = foo => { //do something }const dosomethingElseAgain = (foo, bar) => { //do something }
Starting with ES6/ES2015, functions can have default values for the parameters:
const dosomething = (foo = 1, bar = 'hey') => { //do something }
This allows you to call a function without filling all the parameters:
dosomething(3) dosomething()
ES2018 introduced trailing commas for parameters, a feature that helps reducing bugs due to missing commas when moving around parameters (e.g. moving the last in the middle):
const dosomething = (foo = 1, bar = 'hey') => { //do something }dosomething(2, 'ho!')
You can wrap all your arguments in an array, and use the spread operator when calling the function:
const dosomething = (foo = 1, bar = 'hey') => { //do something } const args = [2, 'ho!'] dosomething(...args)
With many parameters, remembering the order can be difficult. Using objects, destructuring allows to keep the parameter names:
Return valuesReturn values
const dosomething = ({ foo = 1, bar = 'hey' }) => { //do something console.log(foo) // 2 console.log(bar) // 'ho!' } const args = { foo: 2, bar: 'ho!' } dosomething(args)
Every function returns a value, which by default is
undefined.
Any function is terminated when its lines of code end, or when the execution flow finds a
return keyword.
When JavaScript encounters this keyword it exits the function execution and gives control back to its caller.
If you pass a value, that value is returned as the result of the function:
const dosomething = () => { return 'test' } const result = dosomething() // result === 'test'
You can only return one value.
To simulate returning multiple values, you can return an object literal, or an array, and use a destructuring assignment when calling the function.
Using arrays:
Using objects:
Functions can be defined inside other functions:
const dosomething = () => { const dosomethingelse = () => {} dosomethingelse() return 'test' }
The nested function is scoped to the outside function, and cannot be called from the outside.
When used as object properties, functions are called methods:
const car = { brand: 'Ford', model: 'Fiesta', start: function() { console.log(`Started`) } }car.start()
"this"in arrow functions
There’s an important behavior of Arrow Functions vs regular Functions when used as object methods. Consider this example:
const car = { brand: 'Ford', model: 'Fiesta', start: function() { console.log(`Started ${this.brand} ${this.model}`) }, stop: () => { console.log(`Stopped ${this.brand} ${this.model}`) } }
The
stop() method does not work as you would expect.).
An IIFE is a function that’s immediately executed right after its declaration:
;(function dosomething() { console.log('executed') })()
You can assign the result to a variable:
const something = (function dosomething() { return 'something' })()
They are very handy, as you don’t need to separately call the function after its definition.
JavaScript before executing your code reorders it according to some rules.
Functions in particular are moved at the top of their scope. This is why it’s legal to write
dosomething() function dosomething() { console.log('did something') }
Internally, JavaScript moves the function before its call, along with all the other functions found in the same scope:
function dosomething() { console.log('did something') } dosomething()
Now, if you use named function expressions, since you’re using variables something different happens. The variable declaration is hoisted, but not the value, so not the function.
dosomething() const dosomething = function dosomething() { console.log('did something') }
Not going to work:
This is because what happens internally is:
const dosomething dos.
Arrow functions allow you to have an implicit return: values are returned without having to use the
return keyword.
It works when there is a on-line statement in the function body:
const myFunction = () => 'test' myFunction() //'test'
Another example, returning an object (remember to wrap the curly brackets in parentheses to avoid it being considered the wrapping function body brackets):
const myFunction = () => ({value: 'test'}) myFunction() //{value: 'test'}
thisworks as well, when instantiating an object. It:
ClosuresClosures
const link = document.querySelector('#link') link.addEventListener('click', () => { // this === window })const link = document.querySelector('#link') link.addEventListener('click', function() { // this === link })
Here’s a gentle introduction to the topic of closures, which are key to understanding how JavaScript functions work.
If you’ve ever written a function in JavaScript, you’ve already made use of closures.
It’s a key topic to understand, which has implications for the things you can do.
When a function is run, it’s executed with the scope that was in place when it was defined, and not with the state that’s in place when it is executed.
The scope basically is the set of variables which are visible.
A function remembers its Lexical Scope, and it’s able to access variables that were defined in the parent scope.
In short, a function has an entire baggage of variables it can access.
Let me immediately give an example to clarify this.
const bark = dog => { const say = `${dog} barked!` ;(() => console.log(say))() }bark(`Roger`)
This logs to the console
Roger barked!, as expected.
What if you want to return the action instead:
const prepareBark = dog => { const say = `${dog} barked!` return () => console.log(say) }const bark = prepareBark(`Roger`)bark()
This snippet also logs to the console
Roger barked!.
Let’s make one last example, which reuses
prepareBark for two different dogs:
const prepareBark = dog => { const say = `${dog} barked!` return () => { console.log(say) } }const rogerBark = prepareBark(`Roger`) const sydBark = prepareBark(`Syd`)rogerBark() sydBark()
This prints
Roger barked! Syd barked!
As you can see, the state of the variable
say is linked to the function that's returned from
prepareBark().
Also notice that we redefine a new
say variable the second time we call
prepareBark(), but that does not affect the state of the first
prepareBark() scope.
This is how a closure works: the function that’s returned keeps the original state in its scope.Arrays
JavaScript arrays over time got more and more features, and sometimes it’s tricky to know when to use some construct vs another. This section aims to explain what you should use, as of 2018.
const a = [] const a = [1, 2, 3] const a = Array.of(1, 2, 3) const a = Array(6).fill(1) //init an array of 6 items of value 1
Don’t use the old syntax (just use it for typed arrays)
const a = new Array() //never use const a = new Array(1, 2, 3) //never use
const l = a.length
every
a.every(f)
Iterates
a until
f() returns false
some
a.some(f)
Iterates
a until
f() returns true
const b = a.map(f)
Iterates
a and builds a new array with the result of executing
f() on each
a element
const b = a.filter(f)
Iterates
a and builds a new array with elements of
a that returned true when executing
f() on each
a element
ES6
a.forEach(f)
Iterates
f on
a without a way to stop
Example:
for..offor..of
a.forEach(v => { console.log(v) })
ES6
forfor
for (let v of a) { console.log(v) }
for (let i = 0; i < a.length; i += 1) { //a[i] }
Iterates
a, can be stopped using
return or
break and an iteration can be skipped using
continue
ES6
Getting the iterator from an array returns an iterator of values
const a = [1, 2, 3] let it = a[Symbol.iterator]()console.log(it.next().value) //1 console.log(it.next().value) //2 console console.log(it.next().value) //1 console.log(it.next().value) //2
.next() returns
undefined when the array ends. You can also detect if the iteration ended by looking at
it.next() which returns a
value, done pair.
done is always false until the last element, which returns
true.
a.push(4)
a.unshift(0) a.unshift(-2, -1)
From the end
a.pop()
From the beginning
a.shift()
At a random position
a.splice(0, 2) // get the first 2 items a.splice(3, 2) // get the 2 items starting from index 3
Do not use
remove() as it leaves behind undefined values.
a.splice(2, 3, 2, 'a', 'b') //removes 3 items starting from //index 2, and adds 2 items, // still starting from index 2
const a = [1, 2] const b = [3, 4] a.concat(b) // 1, 2, 3, 4
a.indexOf()
Returns the index of the first matching item found, or -1 if not found
a.lastIndexOf()
Returns the index of the last matching item found, or -1 if not foundES })
a.includes(value)
Returns true if
a contains
value.
a.includes(value, i)
Returns true if
a contains
value after the position
i.
Sort the arraySort the array
a.slice()()
a.toString()
Returns a string representation of an array
a.join()
Returns a string concatenation of the array elements. Pass a parameter to add a custom separator:
a.join(', ')
const b = Array.from(a) const b = Array.of(...a)
const b = Array.from(a, x => x % 2 == 0)
LoopsLoops
const a = [1, 2, 3, 4] a.copyWithin(0, 2) // [3, 4, 3, 4] const b = [1, 2, 3, 4, 5] b.copyWithin(0, 2) // [3, 4, 5, 4, 5] //0 is where to start copying into, // 2 is where to start copying from const c = [1, 2, 3, 4, 5] c.copyWithin(0, 2, 4) // [3, 4, 3, 4, 5] //4 is an end index
JavaScript provides many ways to iterate through loops. This section explains all the various loop possibilities in modern JavaScript with a small example and the main properties.
for
const list = ['a', 'b', 'c'] for (let i = 0; i < list.length; i++) { console.log(list[i]) //value console.log(i) //index }
forloop using
break
forloop using
continue
Introduced in ES5. Given an array, you can iterate over its properties using
list.forEach():
const list = ['a', 'b', 'c'] list.forEach((item, index) => { console.log(item) //value console.log(index) //index })//index is optional list.forEach(item => console.log(item))
Unfortunately you cannot break out of this loop.
do...while
const list = ['a', 'b', 'c'] let i = 0 do {
const list = ['a', 'b', 'c'] let i = 0 while
Iterates all the enumerable properties of an object, giving the property names.
for (let property in object) { console.log(property) //property name console.log(object[property]) //property value }
for...of
ES2015 introduced the
for...of loop, which combines the conciseness of forEach with the ability to break:
//iterate over the value for ...invs
for...of
The difference with
for...in is:
for...ofiterates over the property values
for...initerates the property names:
This style of event handlers is very rarely used today, due to its constrains, but it was the only way in the early days of JavaScript:
<a href="site.com" onclick="dosomething();">A link</a>() })
Here’s a list of the most common events you will likely handle.
load is fired on
window and the
body element when the page has finished loading.)
keydown fires when a keyboard button is pressed (and any time the key repeats while the button stays pressed).
keyup is fired when the key is released.:
The Event LoopThe Event Loop
let cached = null window.addEventListener('scroll', event => { if (!cached) { setTimeout(() => { //you can access the original event at `cached` cached = null }, 100) } cached = event })
The Event Loop is one of the most important aspects to understand about JavaScript.., filesystem.Queuing function execution().
At this point the call stack looks like this:
Here is the execution order for all the functions in our program:
Why is this happening?: baz, before bar bar
That’s a big difference between Promises (and Async/await, which is built on promises) and plain old asynchronous functions through
setTimeout() or other platform APIs.
JavaScript is synchronous by default, and is single threaded. This means that code cannot create new threads and run in parallel. Let’s learn what asynchronous code means and how it looks..
Promises are one way to deal with asynchronous code, without writing too many callbacks in your code.
Although being around since the function continues its execution while the promise does itsconst, andnew Promise((resolve, reject) => { reject('Error') }) .catch((err) => { console.error(err) })
If inside the
catch() you raise an error, you can append a second
catch() to handle it, and so on.
new Promise((resolve, reject) => { throw new Error('Error') }) .catch((err) => { throw new Error('Error') }) .catch((err) => { console.error(err) }):
Async and AwaitAsync and Await
const first = new Promise((resolve, reject) => { setTimeout(resolve, 500, 'first') }) const second = new Promise((resolve, reject) => { setTimeout(resolve, 100, 'second') })Promise.race([first, second]).then((result) => { console.log(result) // second })
Now we’ll discover the modern approach to asynchronous functions in JavaScript. JavaScript evolved in a very short time from callbacks to Promises,:
0 1 2 3 4
but actually what happens is this:
5 5 5 5 5:
0 1 2 3 4:
TimersTimers
const operations = []for (var i = 0; i < 5; i++) { operations.push(((j) => { return () => console.log(j) })(i)) }for (const operation of operations) { operation() }
When writing JavaScript code, you might want to delay the execution of a function. We’ll discuss how to use setTimeout and setInterval to schedule functions in the future.
setTimeout()
When writing JavaScript code, you might want to delay the execution of a function.
This is the job of
setTimeout. You specify a callback function to execute later, and a value expressing how execute(() => { if (App.somethingIWait === 'arrived') { clearInterval(interval) return } // available in Node.js, through the Timers module.
Node.js also provides
setImmediate(), which is equivalent to using
setTimeout(() => {}, 0), mostly used to work with the Node.js Event Loop.!
You cannot bind a value to an arrow function, like you do with normal functions.
It’s simply not possible due to the way they work.
this is lexically bound, which means its value is derived from the context where they are defined..
In event handlers callbacks,
this refers to the HTML element that received the event:
document.querySelector('#button').addEventListener('click', function(e) { console.log(this) //HTMLElement }
You can bind it using
Strict ModeStrict Mode
document.querySelector('#button').addEventListener( 'click', function(e) { console.log(this) //Window if global, or your context }.bind(this) ) test.testing = true //true test.testing //undefined
Strict mode fails in all those cases:
;(() => { 'use strict' true.false = ''( //TypeError: Cannot create property 'false' on boolean 'true' 1 ).name = 'xxx' //TypeError: Cannot create property 'name' on number '1' 'test'.testing = true //TypeError: Cannot create property 'testing' on string 'test' })()
In sloppy mode, if you try to delete a property that you cannot delete, JavaScript simply returns false, while in Strict Mode, it raises a TypeError:
delete Object.prototype( //false () => { 'use strict' delete Object.prototype //TypeError: Cannot delete property 'prototype' of function Object() { [native code] } } )()
with
Strict Mode disables the
with keyword, to remove some edge cases and allow more optimization at the compiler level.() { /* */ }())(() => { /* */ }())
There is some weirder syntax that you can use to create an IIFE, but it’s very rarely used in the real world, and it relies on using any unary operator:
;-(function() { /* */ })() +(function() { /* */ })()~(function() { /* */ })()!(function() { /* */ })()
(does not work with arrow functions)
An IIFE can also be named regular functions (not arrow functions). This does not change the fact that the function does not “leak” to the global scope, and it cannot be invoked again after its execution:
;(function doSomething() { /* */ })().
Addition (+)
const three = 1 + 2 const four = three + 1
The
+ operator also serves as string concatenation if you use strings, so pay attention:
const three = 1 + 2 three + 1 // 4 'three' + 1 // three1
Subtraction (-)
const two = 4 - 2
Division (/)).
1 / 0 //Infinity -1 / 0 //-Infinity
Remainder (%)
The remainder is a very useful calculation in many use cases:
const result = 20 % 5 //result === 0 const result = 20 % 7 //result === 6
A reminder by zero is always
NaN, a special value that means "Not a Number":
1 % 0 //NaN -1 % 0 //NaN
Multiplication (*)
1 * 2 //2 -1 * 2 //-2
Exponentiation (**)
Raise the first operand to the power second operand
Unary operatorsUnary operators
1 ** 2 //1 2 ** 1 //2 2 ** 2 //4 2 ** 8 //256 8 ** 2 //64
Increment (++)
Increment a number. This is a unary operator, and if put before the number, it returns the value incremented.
If put after the number, it returns the original value, then increments it.
let x = 0 x++ //0 x //1 ++x //2
Decrement ( — )
Works like the increment operator, except it decrements the value.
let x = 0 x-- //0 x //-1 --x //-2
Unary negation (-)
Return the negation of the operand
let x = 2 -x //-2 x //2
Unary plus (+)
If the operand is not a number, it tries to convert it. Otherwise if the operand is already a number, it does nothing.

ES Modules is the ECMAScript standard for working with modules. While Node.js has been using the CommonJS standard for a long time, the browser never had a module system. syntax to import a module is:
import package from 'module-name'

const package = require('module-name')
A module is a JavaScript file that exports one or more value special

Modules are fetched using CORS. This means that if you reference scripts from other domains, they must have a valid CORS header that allows cross-site loading (like
Access-Control-Allow-Origin: *) exports.b = 2 exports.c = 3

const { a, b, c } = require('./uppercase.js')

To end with, a guide to a few terms used in frontend development that might be alien to you.
In JavaScript a block is delimited curly braces (
{}). An
if statement contains a block, a
for loop contains a block.
With Function Scoping, any variable defined in a block is visible and accessible from inside the whole block, but not outside of it.
A callback is a function that’s invoked when something happens. A click event associated to an element has a callback function that’s invoked when the user clicks the element. A fetch request has a callback that’s called when the resource is downloaded..
With Function Scoping, any variable defined in a function is visible and accessible from inside the whole function.
A variable is immutable when its value cannot change after it’s created. A mutable variable can be changed. The same applies to objects and arrays.
Lexical Scoping is a particular kind of scoping where variables of a parent function are made available to inner functions as well. The scope of an inner function also includes the scope of a parent function.
A polyfill is a way to provide new functionality available in modern JavaScript or a modern browser API to older browsers. A polyfill is a particular kind of shim.
A function that has no side effects (does not modify external resources), and its output is only determined by the arguments. You could call this function 1M times, and given the same set of arguments, the output will always be the same.
JavaScript with
var and
let declaration allows you to reassign a variable indefinitely. With
constdeclarations you effectively declare an immutable value for strings, integers, booleans, and an object that cannot be reassigned (but you can still modify it through its methods).
Scope is the set of variables that’s visible to a part of the program.
Scoping is the set of rules that’s defined in a programming language to determine the value of a variable.
A shim is a little wrapper around a functionality, or API. It’s generally used to abstract something, pre-fill parameters or add a polyfill for browsers that do not support some functionality. You can consider it like a compatibility layer.
A side effect is when a function interacts with some other function or object outside it. Interaction with the network or the file system, or with the UI, are all side effects.
State usually comes into play when talking about Components. A component can be stateful if it manages its own data, or stateless if it doesn’t.
A stateful component, function or class manages its own state (data). It could store an array, a counter or anything else.
A stateless component, function or class is also called dumb because it’s incapable of having its own data to make decisions, so its output or presentation is entirely based on its arguments. This implies that pure functions are stateless.!

Error trying to run/export a mobile applicationGregoriusIII Aug 17, 2013 4:15 PM
Hi,
I'm suck with a problem regarding Flashbuilder 4.7. I have a project that I need to get going on a new machine. I have this project already working on a Mac but need to move to a new Windows machine. The problem when I try to run the project on the new machine I get an error which looks like this:
Process terminated unexpectedly. invalid application descriptor: Unknown namespace: 768x1004:768x1024 -XscreenDPI 132 -XversionPlatform IOS C:\flashbuilder\tablet\bin\Ipad-app.xml C:\flashbuilder\tablet\bin
If I create a new project everything works as expected. This is probably something basic but I'm stuck at this. Any ponters in the right direction would be much appreciated.
Best regards
Gregorius

Aug 17, 2013 9:30 PM (in response to GregoriusIII)
In the project's files there is a –app.xml file. One of the very first lines defines the namespace which is the API version for the app. 4.7 defaults to 3.1, IIRC, so somehow you've upgraded your AIR SDK to 3.4 but the destination machine is still on AIR SDK 3.1 which doesn't know about 3.4.
Either change the version back to 3.1 or upgrade the AIR SDK.
2. Re: Error trying to run/export a mobile applicationGregoriusIII Aug 18, 2013 11:30 AM (in response to Flex harUI)
I'm a bit confused. In the FB preferences air 3.4 is listed as the version used. When I check for updated the updater reports that everything is up do date. In the Flex tab 4.6 is used. If I need to download an updated version of the air sdk is this the proper way to do it?
3. Re: Error trying to run/export a mobile applicationFlex harUI
Aug 18, 2013 10:51 PM (in response to GregoriusIII)
The release notes for Flex SDK 4.6 say that AIR 3.1 is the default. See
If you overlay a Flex SDK with a newer AIR SDK, it updates the minimum required version, so that may be what you are seeing in preferences.
To overlay a Flex SDK, don't use the link you provided, try this one:
Also note that when you download recent AIR SDKs, make sure you download a Flex-compatible version. The default AIR SDKs are not always Flex SDKs.

I don't understand the purpose of super() at all and what it does
I'm completely just confused on the super() function, but none of these explanations are helping, what exactly does super do? And how does the parent class even impact the sneaky attribute??
2 Answers
boi8,568 Points
Since you're a beginner, I'll try to make you understand what you need to understand about
super(), in very simple terms.
consider this code;
import random class Character: def __init__(self, name, **kwargs): self.name = name for key, value in kwargs.items(): setattr(self, key, value)
Do you see the
self.name attribute in the
Character class? Good, now suppose you want to create another class named
Thief and set an
__init__ function with extra attributes also, inheriting everything from the
Character class, so you would probably do something like this 👇
import random class Character: def __init__(self, name, **kwargs): self.name = name for key, value in kwargs.items(): setattr(self, key, value) class Thief(Character): def __init__(self, stealth, endurance, sneaky): self.stealth = stealth self.endurance = endurance self.sneaky = sneaky
Good, now run the program, but wait, there are two
__init__ methods, one from the
Character class and other from the
Thief class, since only one
__init__ method can run at a time, is there a way to run both of the
__init__ methods together? like combined? YES, this is where
super() comes into picture.
To run both of the
__init__ methods you can use
super() like this;
import random class Character: def __init__(self, name, **kwargs): self.name = name for key, value in kwargs.items(): setattr(self, key, value) class Thief(Character): def __init__(self, name, stealth, endurance, sneaky, **kwargs):👈#Must include parameters from the inherited class #in this case those parameters are "name" and "**kwargs" super().__init__(name, **kwargs) 👈#Used super() here to combine the "Character class __init__" method with #the "Thief class __init__" method self.stealth = stealth self.endurance = endurance self.sneaky = sneaky #Notice you don't need to set attributes of the "Character" class here, because you don't need to set it, the super() #handles that as well
Go into the REPL
>>> from characters import Thief >>> jayda = Thief("Jayda hendrickson", "42%", "50%", "True") >>> jayda.name "Jayda hendrickson" >>> jayda.stealth "42%" >>> jayda.endurance "50%" >>> jayda.sneaky "True"
As you progress further into the course you will understand much more about the usage of
super(), for now try to understand why did Kenneth use it in this video. I recommend you play around with
super() a bit before going further into the course.
Note :This explanation is to give you somewhat idea of the use of
super(), in reality
super() is used when you want to override any method and want to access the version in the parent class.
You should also check out pro Josh Keenan's and the veteran Steven Parker's explanations.

Don't psych yourself out of this.
super()just calls the constructor function on the parent class and gives the inheriting class access to all the properties and methods available on the parent class.

Howdy, I wanted to make the 0.9 beta tonight (well, last night...) but I've just burned several hours trying to track an intermittent failure in a Twisted-using test that I can't seem to pin down. Since the problem is only on a single test, I'm giving up for now. But I just committed the last critical piece of testing machinery that gave me a hard time: the ability to correctly execute in docstrings tests that probe ipython-specific features, like complete(x) where x is in the namespace. This requires a delicate dance with nose and doctest, but I think I finally got a solid solution. The sugar is still missing, so for now the test suite will be really only for developers, but hopefully next week I can add a user-visible layer that makes it easy for users to run and that handles gracefully missing components (like twisted, guis, objc, etc)..

TypeScript has become increasingly popular due to numerous benefits recently added to the code, such as static type-checking robustness, understandability, and type interface.
And when TypeScript is used with React, it offers improved developer experience and more predictability to the project.
In this guide, we will learn how to use TypeScript with React Context by building a to-do app from scratch. Let’s dive in.
Prerequisites
To get the most out of this tutorial, you need a basic understanding of React and TypeScript. If you’re new to web development, you can start with this React TypeScript tutorial to get familiar with these technologies.
Setting up
To create a new app, I will use Create React App in order to have a modern configuration with no hassle. But, you are welcome to set up a new app from scratch using Webpack.
Begin by opening your terminal and running the following command:
npx create-react-app react-context-todo --template typescript
To enable TypeScript when using Create React App, you need to add the flag
--template typescript, otherwise the app will support only JavaScript.
Next, let’s structure the project as follows:
├── src | ├── components | | ├── AddTodo.tsx | | └── Todo.tsx | ├── containers | | └── Todos.tsx | ├── context | | └── todoContext.tsx | ├── App.tsx | ├── index.css | ├── index.tsx | ├── react-app-env.d.ts | └── type.d.ts ├── tsconfig.json ├── package.json └── yarn.lock
Here, there are two files to underline:
- The
context/todoContext.tsxfile that serves as a context for the project
- The
type.d.tsfile that contains the TypeScript Types. The extension
.d.tsallows using the types in other files without importing them
With this in place, we can now get our hands dirty and code something meaningful.
Create the to-do type
TypeScript Type allows you to define what a variable or function should expect as a value in order to help the compiler catch errors before runtime.
type.d.ts
interface ITodo { id: number title: string description: string status: boolean } type ContextType = { todos: ITodo[] saveTodo: (todo: ITodo) => void updateTodo: (id: number) => void }
As you can see, the interface
ITodo defines the shape of a to-do object. Next, we have the type
ContextType that expects an array of to-dos and the methods to add or update a to-do.
Create the context
React Context allows you to share and manage state across your components without passing down props. The context will provide the data to just the components that need to consume it. my first description", status: false }, { id: 2, title: "post 2", description: "this is my second description", status: true } ]);
Here, we start by creating a new context and set its type to match
ContextType or
null. The latter is using
here to initialize the context with a null value. Next, we create the component
TodoProvider that provides the context to the component consumers. Here, I initialize the state with some data to have
todos to work.
context/todoContext.tsx]) } }) }
The function
saveTodo will create a new to-do based on the interface
ITodo and then append the object to the array of to-dos. The next function,
updateTodo, will look for the id of the to-do passed as a parameter in the array of to-dos and then update it.
context/todoContext.tsx
return ( {children} ); }; export default TodoProvider;
Next, we pass the values to the context to make them consumable for the components. a description', status: false, }, { id: 2, title: 'post 2', description: 'this is a description', status: true, }, ])]) } }) } return ( {children} ) } export default TodoProvider
With this, we are now able to consume the context. So, let’s create the components in the next section.
Create the components and consume the context
components/AddTodo.tsx
import * as React from 'react' import { TodoContext } from '../context/todoContext' const AddTodo: React.FC = () => { const { saveTodo } = React.useContext(TodoContext) as ContextType const [formData, setFormData] = React.useState<ITodo | {}>() const handleForm = (e: React.FormEvent<HTMLInputElement>): void => { setFormData({ ...formData, [e.currentTarget.id]: e.currentTarget.value, }) } const handleSaveTodo = (e: React.FormEvent, formData: ITodo | any) => { e.preventDefault() saveTodo(formData) } return ( <form className='Form' onSubmit={(e) => handleSaveTodo(e, formData)}> <div> <div> <label htmlFor='name'>Title</label> <input onChange={handleForm} </div> <div> <label htmlFor='description'>Description</label> <input onChange={handleForm} </div> </div> <button disabled={formData === undefined ? true : false}>Add Todo</button> </form> ) } export default AddTodo
Here, we have a form component that allows handling data entered by the user using the
useState hook. Once we get the form data, we use the function
saveTodo pulled from the context object to add a new to-do.
Note that I use typecasting on the
useContext hook to avoid TypeScript throwing errors because the context will be null at the beginning.
components/Todo.tsx
import * as React from 'react' type Props = { todo: ITodo updateTodo: (id: number) => void } const Todo: React.FC<Props> = ({ todo, updateTodo }) => { const checkTodo: string = todo.status ? `line-through` : '' return ( <div className='Card'> <div className='Card--text'> <h1 className={checkTodo}>{todo.title}</h1> <span className={checkTodo}>{todo.description}</span> </div> <button onClick={() => updateTodo(todo.id)} className={todo.status ? `hide-button` : 'Card--button'} > Complete </button> </div> ) } export default Todo
As you can see here, we have a presentational component that shows a single to-do. It receives the to-do object and the function to update it as parameters that need to match the
Props type defined above.
import * as React from 'react' import { TodoContext } from '../context/todoContext' import Todo from '../components/Todo' const Todos = () => { const { todos, updateTodo } = React.useContext(TodoContext) as ContextType return ( <> {todos.map((todo: ITodo) => ( ))} </> ) } export default Todos
This component shows the list of to-dos when the page loads. It pulls the
todos and the function
updateTodo from the to-do context. Next, we loop through the array and pass to the
Todo component the object to show. With this step forward, we are now able to provide the to-do context in the
App.tsx file to finish up building the app. So, let’s use the context provider in the next part.
Provide the context
import * as React from 'react' import TodoProvider from './context/todoContext' import Todos from './containers/Todos' import AddTodo from './components/AddTodo' import './styles.css' export default function App() { return ( <TodoProvider> <main className='App'> <h1>My Todos</h1> <AddTodo /> <Todos /> </main> </TodoProvider> ) }
Here, we import the
TodoProvider component that wraps the consumers of the to-do context. That said, we can now access the
todos array and the function to add or update a to-do using the
useContext hook in other components.
With this, we can now open the project on the terminal and run the following command:
yarn start
Or
npm start
If everything works, you’ll be able to see this in the browser:
Great! With that final touch, we have now finished building a to-do app using React Context and TypeScript.
You can find the finished project here.
Conclusion
TypeScript is a great language that makes our code better. In this tutorial, we’ve learned how to use TypeScript with React Context. Hopefully, it helps you with your next project._3<<
TypeScript brings type safety to JavaScript. There can be a tension between type safety and readable code. Watch the recording for a deep dive on some new features of TypeScript 4.4.

For something closer to real life I would recommend using this pattern for context, it checks for initial context value and has more ergonomic type safety
I think there is a mistake here. Because you never expose your provider with

In the last post we discussed the architecture and the features of HDFS . In this post I will try to address how HDFS is able to achieve the high data availability, high data transfers and robustness despite the hardware failures.
When a client submits a file to be stored on HDFS, NameNode internally accepts the request and breaks down the file into blocks.
Say: The input file size is 300 MB. The standard blocksize used by HDFS is 64MB. So the input file is divided into 5 blocks out of which the first 4 blocks are of equal size (64MB) and the size of the last block depends on the leftover chunk of input file.
Each of those blocks will be replicated and distributed across different nodes to avoid the danger of losing the blocks due to hardware failures. Clients can specify the replication factor for the file when he stores it into HDFS.
Img source:
Fig: DataNodes holding blocks of multiple files with a replication factor of 2. The NameNode maps the filenames onto the block ids.
Q: What is the technique employed by NameNodes to distribute the blocks onto DataNodes?
Answer: Rack Awareness.
In a datacenter, machines are arranged across racks. In each rack, there are multiple machines. Data transfers within the rack is much faster than the data transfer across the racks (Because of the overhead of data going through the internal rack switches and then across-the-rack-switch). When you install the Hadoop software, you need to specify the network topology. This is a manual admin task. NameNode uses this information to distribute the blocks. If the replication factor is 3, the policy is to put one replica on the local node in the same rack, another on a node in a different remote rack and the last on a different node in the same remote rack.
Q: How are high data transfers achieved?
Answer: Since the same block of data is replicated across various machines, the data can be read in parallel. However the writes become expensive. That’s the reason why HDFS is more suitable for write-once-read-any number of times (WORA) setup.
So far, we have looked at how HDFS achieves high data availability despite failures, let us now shift our radar to see how HDFS achieves the robustness.
Robustness: In this section, we will see how HDFS stores the data reliably in the presence of failures. The three common type of failures are as follows:
i) Data Node Failures: DataNodes sends heart beat messages back to NameNode every x (say 3) seconds to indicate that they are up and running. They also send the Block Report containing all the blocks that are stored on them to the NameNode. Based on the Block Reports received from the DataNodes and theNameNodes will update its metadata as required. If the NameNode does not receive these messages, it detects the failure of the DataNodes and marks these nodes as dead. Moving forward, it does not forward any requests to these nodes. The NameNodes may also start re-replication of the blocks as required due to the death of DataNodes.
ii) Data Corruption in DataNodes: NameNode computes the checksum of the blocks it distributes to the DataNodes and stores this information in a hidden file in a namespace. It computes the checksum again when it retrieves the data from DataNodes. If the checksum does not match,the NameNode detects the block corruption and then initiates the data transfer from some other DataNode.
iii) NameNode Failure: NameNode machine is a single point of failure for HDFS. If the NameNode fails, then manual intervention is required.
In this post, we saw how HDFS achieves high data availability, high data transfers and robustness despite hardware failures due to commodity hardware. I hope you had a good understanding of HDFS. In the next post, we will discuss about configuring Hadoop in a SingleNode/MultiNode setup.

No you cannot. But you can pass the variables by reference so that the changes are reflected in the original variables. For example
void test(int &a,int &b) { a=a+1; b=b+1; } int main() { int c=23,d=6; test(c,d); cout<<c<<endl<<d; cin.get(); cin.ignore(); return 0; }
Here the values of c and d will be incremented by 1 i.e. changes will be reflected in the original variables.
Alternatively, if you want to return something you could create a struct/class which contains the data you want to return.
#include <iostream> #include <string> #include <fstream> struct names { std::string first_name; std::string last_name; }; names read_from_file( std::ifstream &in ) { names i_names; in >> i_names.first_name >> i_names.last_name; return i_names; }
Probably isn't the best example of how to do it but gives you an idea anyhow.
Alternatively, you can make a class where the return values are fields and the object can be called like a function by overloading the () operator:
#include <iostream> #include <string> struct Name { std::string First; std::string Last; void operator()() { std::cin >> First >> Last; } }; int main() { Name getName; getName(); std::cout << getName.Last << ", " << getName.First << '\n'; }
c++98 has the convenient
std::pair<> .
c++09 also has
std::tuple<> .
#include <utility> #include <algorithm> #include <tuple> std::pair<int,int> min_n_max( const int* arr, std::size_t N ) { // invariant: N > 0 int low = arr[0] ; int high = arr[0] ; for( std::size_t i=1 ; i<N ; ++i ) { low = std::min( low, arr[i] ) ; high = std::max( high, arr[i] ) ; } return std::make_pair(low,high) ; } std::tuple<int,int,double> min_max_n_avg( const int* arr, std::size_t N ) { // invariant: N > 0 int low = arr[0] ; int high = arr[0] ; int sum = arr[0] ; for( std::size_t i=1 ; i<N ; ++i ) { low = std::min( low, arr[i] ) ; high = std::max( high, arr[i] ) ; sum += arr[i] ; } return std::make_tuple( low, high, sum/double(N) ) ; }
> .. I have a large quantity of values...
if the values are in a file, pass the file (istream) to the minmax function. in the function, read the values one by one and check for min/max.
if the values are programmatically generated, pass the generator function (or function object) to the minmax | https://www.daniweb.com/programming/software-development/threads/123503/function-to-return-two-values | CC-MAIN-2016-50 | refinedweb | 374 | 52.19 |

As usual, I have the first extension built and released
Ext.ux.TouchGridPanel was a huge success, thank you for everyone's input as it matured (still has room). Sencha Touch 2 should not be without a grid component either and as of the first developer preview there is no native grid component.
Ext.ux.touch.grid is the namespace and like the new namespacing Sencha Touch 2 and Ext JS 4 started, I followed with this.
The main class is Ext.ux.touch.grid.View which is just a customized DataView. It supports having a header and of course all the rows. You can have cell renderers (uses XTemplate's renderers instead of any processData method).
Ext.ux.touch.grid.View is pretty stripped down. In fact it doesn't even support sorting. I haven't left you out in the cold, I just wanted to have a lightweight grid component.
Like Ext JS 4's grid architecture, Ext.ux.touch.grid has the concept of features. Features are basically plugins. Unlike Ext JS 4, I allow you to specify what stage in the grid you want to instantiate a feature. There are two stages, in the constructor and in the initialize methods. Add features to constructorFn array and it will create the feature right before the callParent call. Save for initializeFn array.
Like I said, this is a start. Many things will change to further this grid and also keep inline with the latest Sencha Touch 2 version.

I'm loading in a color image in Python OpenCV and plotting the same. However, the image I get has it's colors all mixed up.
Here is the code:
import cv2
import numpy as np
from numpy import array, arange, uint8
from matplotlib import pyplot as plt
img = cv2.imread('lena_caption.png', cv2.IMREAD_COLOR)
bw_img = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
images = []
images.append(img)
images.append(bw_img)
titles = ['Original Image','BW Image']
for i in xrange(len(images)):
plt.subplot(1,2,i+1),plt.imshow(images[i],'gray')
plt.title(titles[i])
plt.xticks([]),plt.yticks([])
plt.show()
OpenCV uses BGR as its default colour order for images, matplotlib uses RGB. When you display an image loaded with OpenCv in matplotlib the channels will be back to front.
The easiest way of fixing this is to use OpenCV to explicitly convert it back to RGB, much like you do when creating the greyscale image.
RGB_img = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)
And then use that in your plot. | https://codedump.io/share/41Atqgwsl9a1/1/opencv-giving-wrong-color-to-colored-images-on-loading | CC-MAIN-2017-13 | refinedweb | 169 | 57.98 |
This section will provide an introduction to the various concepts, approaches and features that make up SVG. It will probably be quite lengthy. So far, only four introductory sections have been written: HTML and SVG.
Thus, interactive and dynamic effects will be possible on both HTML and SVG using the same
set of scripts.
SVG supports two intended uses:
The following shows a trivial stand-alone SVG file with no content:
<?xml version="1.0"?> <g xmlns="..."> <!-- Insert drawing elements here --> </g>
The simplest drawings can be described by a sequence of drawing elements. The following example draws a rectangle:
... <g> <rectangle x="100" y="100" width="100" height="100" /> </g>
The following shows how a fragment from the SVG namespace could be interspersed into a parent XML grammar:
<?xml version="1.0"?> <ABC xmlns="..." xmlns: ... <svg:rectangle ... /> ... </g>
Drawings done in SVG will be much more accessible that drawings done as image formats for the following reasons:

Troubleshooting Steps:
When you get error in HCI Message log as shown here:
- HTTP response ‘403: Forbidden’ when communicating with
Proposed solution:
Since the called or mapped URL is “https” the sap cloud connector has to trust the Certificate Authority or the issuer of this backend service URL.
Steps to add the Certificate Authority into the Trust store of the SCC.
- Download the Certificate Authority by following the steps:
- Select the Lock gree icon (in google chrome) prefixed to the URL.
- Select the “Connection” tab and “Certificate information” link.
- Click on the “Certificate path” tab and Double click the top root certificate.
- Go-to “Details” tab of the root certificate and “Copy to file” and export it to the default format.
2. Go-to SCC page -> Settings -> Trust Store
3. Browse the Certificate Authority certificate that was downloaded above and Add it to the truststore as shown in the picture below.
References to SAP Cloud Connector guides.
is it not possible to connect On-Premise System without Cloud Connector?
import export is possible using dell boomi interface.
You can connect to on-premise systems without the Cloud Connector. You probably don’t want to allow direct access to backend systems from HCP, though. A reverse proxy setup is the typical solution to that problem.
Hi experts!.
Hi Experts,
I followed all the steps mentioned in this blog, but getting 503 error in the message monitoring.
I am not sure, which link I should download the certificate. I added the certificate in the Trust from SAP ECC system(not sure if this is correct).
Also, when I am trying to check the connection getting error as shown below –
Please suggest, what should be the solution.
Thanks,
Nidhi Srivastava

This would be great but has problems with fixtures:
I saw here:
how to solve this problem and it works!!
Pedro,
Thanks for your comment. All this time, I was putting my fixtures under the /models sub-directory. I thought it was a Django feature and it turns out to be a bug. :)
N00b here. Could you make one of your models have a foreign key to the other one? That would make a more complete guide for us n00bs.
Thanks.
Sure thing. I just added that in as part of the example. Thanks.
Thanks a lot for taking note of my earlier comment.
In the article where it says “You’ll also need to explicitly import each model class in the model module’s __init__.py file”, am I right in saying that the models would need to be imported in the proper order for syncdb etc to work right?
Yup, you are absolutely right. I have added a note at the end:
This is the best “HOW TO” to make split models file in django!!! thanks!!!
This is one of those things that should really be part of the official documentation. I really wish that I’d found this 3hours ago rather than tinkering and surfing for all that time :-(
Great post though btw.
I couldn’t get it to work until I revised my
__init__.pyto simply:
from foo import Foo
from bar import Bar
This works and makes sense since you don’t need to specify the full namespace from the top level.
Thanks for this comment. I was also having failures with the __init__.py file as originally described.
Nizam, great post, very concise. My only comment is that I think it would save people quite a bit of time if you could incorporate this comment into your original post.
Thanks again.
Hi !
I did what you said (thanks by the way, because it was -until recently- very useful!), but when I try to dynamically import some models, I got something strange…
Take a look a my code (which is in myapp.logger.__init__.py) :
from django.conf import settings
for log_hook in settings.LOG_HOOKS :
try :
__import__(log_hook)
except ImportError as e :
pass
#from myapp.logger.hooks.vmm import *
Now, the problem is that when I try to import dynamically, I got some import errors, while if I directly write exactly the same import statement as the one generated, everything goes well…
Any idea to make this dynamic import work would be greatly welcome !!! | http://www.nomadjourney.com/2009/11/splitting-up-django-models/ | CC-MAIN-2018-30 | refinedweb | 428 | 73.58 |
Need help with server namespace
By John Clingan-Oracle on Sep 02, 2004
In my sales office we have a lab where geeks like myself get hands-on time with new Sun technology (hardware and/or software). We recently went through a network ip range change as we consolidated offices. As a consequence, we are re-visiting the naming scheme.
When visiting customers, I like to hear their naming scheme. All sysadmins are guilty of wanting to add "character" to their servers :) "David" and "goliath" in one customer. Another customer uses the star trek theme (suprise) such as "spock", "jim" etc. Hey, anyone else play the boozing star trek game in college where you had to take a drink every time McCoy said "Jim" and slam the drink when McCoy said "Damnit Jim"? OK, I digress.
At home I use the chess opening theme such as "benko" (my favorite), "alekhine", "sicilian", etc. Yeah, I was a pretty good chess player (a USCF strength of about 1750 with a rating in the 1500's due to lack of tournament play). Not great, but solid.
In our lab, machines come in and go out fairly regularly and even the more hardwired machines are multi-purpose over time. I prefer a naming scheme of "server1", "server2", etc. Currently it is "lab1", "lab2", etc. Boring but true. Now with the re-numbering we are considering a new naming theme. I prefer the boring naming theme. Some of my co-workers (like Matt) do not. Daryl, a non-blogger, prefers Sun product code-names as a theme. Not a bad idea.
I am open to a new naming theme, and here is your chance to provide input. What would \*you\* name our servers? Be nice and ... um ... clean.
By the way, if you use "Sun product code-names as a theme", you know you may end up with an Ultra 5 named "starkitty" and a router called "MadHatter" ?
PS. A little Trivia: Netscape's code name for Fastraq server (the home use web server) for Windows 95 was "Mission: Impossible"

Database Servers are named for "red shirt" folks in the Matrix: "Apoc", "Switch", "Mouse" and "Dozer".
The VCS Cluster uses "split personality" names: "Smeagol" And "Gollum" are the current two nodes.
The Application Servers always come in pairs, and thus are named after cartoon pairings: "Nemo" and "Dory", "Pinky" and "Brain", "Ren" and "Stimpy", "Buzz" and "Woody"
Lab boxes are a bit more random, but the general theme are comic books: "Violator", "Punisher", etc.

TL;DR: Throughout this article, we are going to use Flask and Python to develop a RESTful API. We will start by creating an endpoint that returns static data (dictionaries). After, we are going to create a class with two specializations and a few endpoints to insert and retrieve instances of these classes. Finally, will take a look on how to run the API on a Docker container. The final code developed throughout this article can be found in this GitHub repository. I hope you enjoy!
"Flask allows Python developers to create lightweight RESTful APIs."
Summary
This article is divided in the following sections:
- Why Python?
- Why Flask?
- Bootstrapping a Flask Application
- Creating a RESTful Endpoint with Flask
- Mapping Models with Python Classes
- Serializing and Deserializing Objects with Marshmallow
- Dockerizing Flask Applications
- Securing Python APIs with Auth0
- Next Steps
Why Python?
Nowadays, choosing Python to develop applications is becoming a very popular choice. As StackOverflow recently analyzed, Python is one of the fastest-growing programming languages, having surpassed even Java on the number of questions asked on the platform. On GitHub, the language shows signs of mass adoption as well, occupying the third position on the number of opened Pull Requests in 2016.
The huge community that is forming around Python is improving every aspect of the language. More and more open source libraries are being released to address many different subjects, like Artificial Intelligence, Machine Learning, and web development. Besides the great support provided by the overall community, the Python Software Foundation also provides excellent documentation where new adopters can learn its essence fast.
Why Flask?
When it comes to web development on Python, there are two frameworks that are widely used: Django and Flask. Django is older, more mature, and a little bit more popular. On GitHub, this framework has around 28k stars, 1.5k contributors, ~170 releases, and more than 11k forks. On StackOverflow, roughly 1.2% of questions asked in a given month are related to Django.
Flask, although less popular, is not far behind. On GitHub, Flask has almost 30k stars, ~445 contributors, ~21 releases, and almost 10k forks. On StackOverflow, up to 0.2% of questions asked in a given month are related to Flask.
Even though Django is older and having a slightly bigger community, Flask has its strengths. From the ground up, Flask was built with scalability and simplicity in mind. Flask applications are known for being lightweight, mainly when compared to their Django counterparts. Flask developers call it a microframework, where micro (as explained here) means that the goal is to keep the core simple but extensible. Flask won’t make many decisions for us, such as what database to use or what template engine to choose. Lastly, Flask also has extensive documentation that address everything that developers need to start.
Being lightweight, easy to adopt, well-documented, and popular, Flask is a very good option for developing RESTful APIs.
Bootstrapping a Flask Application
First and foremost, we will need to install some dependencies on our development machine. Basically, what we will need to install is Python 3, Pip (Python Package Index), and Flask. Fortunately, the process of installing these dependencies is quite simple.
Installing Python 3
If we are using some recent version of a popular Linux distribution (like Ubuntu), chances are that we already have Python 3 installed on our computer. If we are running Windows, then we will probably need to install Python 3, as this operating system does not ship with any version at all. Python 2 is installed by default on Mac OS and we have to install Python 3 by ourselves.
After installing Python 3 on our machine, we can check that we have everything set up as expected by running the following command:
python --version # Python 3.6.2
Note that the command above might produce a different output in case we have a different Python version. What is important is that the output begins with
Python 3, and not
Python 2. If we get the latter, we can try issuing
python3 --version. If this command produces the correct output, then we have to replace all commands throughout the article.
Installing Pip
[Pip is the recommended tool for installing Python packages. While the official installation page states that
pip is already installed if we're using Python 2 >=
2.7.9 or Python 3 >=
3.4, installing Python through
apt on Ubuntu doesn't install
pip. Therefore, let's check if we do need to install
pip separately, or if we already have it.
# we might need to change pip by pip3 pip --version # pip 9.0.1 ... (python 3.X)
If the command above produces an output similar to
pip 9.0.1 ... (python 3.X), then we are good to go. If we get
pip 9.0.1 ... (python 2.X), then we can try replacing
pip with
pip3. If we are unable to find Pip for Python 3 on our machine, we can follow the instructions here to install Pip.
Installing Flask
We already know what Flask is and its capabilities. Therefore, let's focus on installing it on our machine and testing to see if we can get a basic Flask application running. The first step is to use
pip to install Flask:
# we might need to replace pip with pip3 pip install Flask
After installing the package, we will create a file called
hello.py and add five lines of code to it. As we will use this file just to check if Flask was correctly installed, we don't need to nest it in a new directory.
from flask import Flask app = Flask(__name__) @app.route("/") def hello_world(): return "Hello, World!"
These 5 lines of code are everything we need to handle HTTP requests and return a "Hello, World!" message. To run it, we need to export an environment variable called
FLASK_APP and then execute
flask:
# flask depends on this env variable to find the main file export FLASK_APP=hello.py # now we just need to ask flask to run flask run # * Serving Flask app "hello" # * Running on (Press CTRL+C to quit)
On Ubuntu, we might need to edit the
$PATHvariable to be able to run flask directly. To do that, let's
touch ~/.bash_aliasesand then
echo "export PATH=$PATH:~/.local/bin" >> ~/.bash_aliases.
After executing these commands, we can reach our application by opening a browser and navigating to or by issuing
curl.
Virtual Environments (virtualenv)
Although PyPA—the Python Packaging Authority group—recommends
pip as the tool for installing Python packages, we will need to use another package to manage our project's dependencies. It's true that
pip supports package management through the
requirements.txt file, but the tool lacks some features to be used on serious projects running on different production and development machines. Among its issues, the ones that cause the most problems are:
pipinstalls packages globally, making it hard to manage multiple versions of the same package on the same machine.
requirements.txtneed all dependencies and sub-dependencies listed explicitly, a manual process that is tedious and error-prone.
To solve these issues, we are going to use Pipenv. Pipenv is a dependency manager that isolates projects on private environments, allowing packages to be installed per project. If you’re familiar with NPM or Ruby’s bundler, it's similar in spirit to those tools.
pip install pipenv
Now, to start creating a serious Flask application, let's create a new directory that will hold our source code. In this article, we will create Cashman, a small RESTful API that allows users to manage incomes and expenses. Therefore, we will create a directory called
cashman-flask-project. After that, we will use
pipenv to start our project and manage our dependencies.
# create our project directory and move to it mkdir cashman-flask-project && cd cashman-flask-project # use pipenv to create a Python 3 (--three) virtualenv for our project pipenv --three # install flask a dependency on our project pipenv install flask
The second command creates our virtual environment, where all our dependencies will be installed, and the third one will add Flask as our first dependency. If we check our project's directory, we will see that two files are created after executing these commands:
Pipfile, a file that contains details about our project, like the Python version that we are using and the packages that our project needs.
Pipenv.lock,a file that contains exactly what version of each package our project depends on, and its transitive dependencies.
Python Modules
Like other mainstream programming languages, Python also has the concept of modules to enable developers to organize source code according to subjects/functionalities. Similar to Java packages and C# namespaces, modules in Python are files organized in directories that can be imported by other Python scripts. To create a module on a Python application, we just need to create a folder and add an empty file called
__init__.py to it.
Let's create our first module on our application. This is going to be our main module, with all our RESTful endpoints. Inside the directory that we created for our application, let's create another one with the same name,
cashman. The main
cashman-flask-project directory created before will hold metadata about our project, like what dependencies it has, while this new one will be our module with our Python scripts.
# create source code's root mkdir cashman && cd cashman # create an empty __init__.py file touch __init__.py
Inside the main module, let's create a script called
index.py. In this script, we will define the first endpoint of our application.
from flask import Flask app = Flask(__name__) @app.route("/") def hello_world(): return "Hello, World!"
Just like in the previous example, our application simply returns a "Hello, world!" message. We will start improving it in a second, but first let's create an executable file called
bootstrap.sh in the main directory of our application.
# move to the main directory cd .. # create the file touch bootstrap.sh # make it executable chmod +x bootstrap.sh
The goal of this file is to facilitate the start up of our application. Its source code will be the following:
#!/bin/sh export FLASK_APP=./cashman/index.py source $(pipenv --venv)/bin/activate flask run -h 0.0.0.0
The first command defines the main script to be executed by Flask, just like we did when we ran the "Hello, world!" application. The second one activates the virtual environment, created by
pipenv, so our application can find and execute its dependencies. Lastly, we run our Flask application listening to all interfaces on the computer (
-h 0.0.0.0).
To check that this script is working correctly, we can execute
./bootstrap.sh now. This will give us a similar result to when we executed the "Hello, world!" application.
# * Serving Flask app "cashman.index" # * Running on (Press CTRL+C to quit)
Creating a RESTful Endpoint with Flask
Now that we have our application structured, we can start defining some relevant endpoints. As mentioned before, the goal of our application is to help users to manage incomes and expenses. To get our feet wet, we will start by defining two endpoints to handle incomes. Let's replace the contents of the
./cashman/index.py file with the following:
from flask import Flask, jsonify, request app = Flask(__name__) incomes = [ { 'description': 'salary', 'amount': 5000 } ] @app.route('/incomes') def get_incomes(): return jsonify(incomes) @app.route('/incomes', methods=['POST']) def add_income(): incomes.append(request.get_json()) return '', 204
Since we are improving our application, we have removed the endpoint that returned "Hello, world!" to users. In its place, we defined an endpoint to handle HTTP
GET request to return incomes, and another endpoint to handle HTTP
POST requests to add new incomes. These endpoints are annotated with
@app.route to define that they listen to requests on the
/incomes endpoint. Flask provides a great documentation on what exactly this does.
Right now, we are manipulating incomes as dictionaries to facilitate the process. We will soon create classes to represent incomes and expenses.
To interact with both endpoints that we have created, we can start our application and issue some HTTP requests:
# start the cashman application ./bootstrap.sh & # get incomes curl # add new income curl -X POST -H "Content-Type: application/json" -d '{ "description": "lottery", "amount": 1000.0 }' # check if lottery was added curl localhost:5000/incomes
Mapping Models with Python Classes
Using dictionaries in a very simple use case like the one above is enough. However, for more complex applications that deal with different entities and have multiple business rules and validations, we might need to encapsulate our data into Python classes.
To learn the process of mapping entities (like incomes) as classes, we will refactor our application. The first thing that we will do is create a submodule to hold all our entities. Let's create a directory called
model inside the
cashman module and add an empty file called
__init__.py on it.
# create model directory inside the cashman module mkdir -p cashman/model # initialize it as a module touch cashman/model/__init__.py
Mapping a Python Superclass
Inside this new module/directory, we will create three classes:
Transaction,
Income,
Expense. The first class will be the base for the two others, and we will call it
Transaction. Let's create a file called
transaction.py in the
model directory with the following code:
import datetime as dt from marshmallow import Schema, fields class Transaction(): def __init__(self, description, amount, type): self.description = description self.amount = amount self.created_at = dt.datetime.now() self.type = type def __repr__(self): return '<Transaction(name={self.description!r})>'.format(self=self) class TransactionSchema(Schema): description = fields.Str() amount = fields.Number() created_at = fields.Date() type = fields.Str()
Note that besides the
Transaction class, we also defined a
TransactionSchema. We will use the latter to deserialize and serialize instances of
Transaction from and to JSON objects. This class inherits from another superclass called
Schema that is defined on a package yet to be installed.
# installing marshmallow as a project dependency pipenv install marshmallow
Marshmallow is a popular Python package for converting complex datatypes, such as objects, to and from native Python datatypes. Basically, we can use this package to validate, serialize, and deserialize data. We won't dive into validation in this article, as it will be the subject of another one. Though, as mentioned, we will use
marshmallow to serialize and deserialize entities through our endpoints.
Mapping Income and Expense as Python Classes
To keep things more organized and meaningful, we won't expose the
Transaction class on our endpoints. We will create two specializations to handle the requests:
Income and
Expense. Let's create a file called
income.py inside the
model module with the following code:
from marshmallow import post_load from .transaction import Transaction, TransactionSchema from .transaction_type import TransactionType class Income(Transaction): def __init__(self, description, amount): super(Income, self).__init__(description, amount, TransactionType.INCOME) def __repr__(self): return '<Income(name={self.description!r})>'.format(self=self) class IncomeSchema(TransactionSchema): @post_load def make_income(self, data): return Income(**data)
The only value that this class adds for our application is that it hardcodes the type of the transaction. This type is a Python enumerator, which we still have to create, that will help us filter transactions in the future. Let's create another file, called
transaction_type.py, inside
model to represent this enumerator:
from enum import Enum class TransactionType(Enum): INCOME = "INCOME" EXPENSE = "EXPENSE"
The code of the enumerator is quite simple. It just defines a class called
TransactionType that inherits from
Enum and that defines two types:
INCOME and
EXPENSE.
Lastly, let's create the class that represents expenses. To do that, let's add a new file called
expense.py inside
model with the following code:
from marshmallow import post_load from .transaction import Transaction, TransactionSchema from .transaction_type import TransactionType class Expense(Transaction): def __init__(self, description, amount): super(Expense, self).__init__(description, -abs(amount), TransactionType.EXPENSE) def __repr__(self): return '<Expense(name={self.description!r})>'.format(self=self) class ExpenseSchema(TransactionSchema): @post_load def make_expense(self, data): return Expense(**data)
Similar to
Income, this class hardcodes the type of the transaction, but now it passes
EXPENSE to the superclass. What makes it different is that it forces the
amount passed to be negative. Therefore, no matter if the user sends a positive or a negative value, we will store it as negative to facilitate calculations.
Serializing and Deserializing Objects with Marshmallow
With the
Transaction superclass and its specializations properly implemented, we can now enhance our endpoints to deal with these classes. Let's replace
./cashman/index.py contents to:
from flask import Flask, jsonify, request from cashman.model.expense import Expense, ExpenseSchema from cashman.model.income import Income, IncomeSchema from cashman.model.transaction_type import TransactionType app = Flask(__name__) transactions = [ Income('Salary', 5000), Income('Dividends', 200), Expense('pizza', 50), Expense('Rock Concert', 100) ] @app.route('/incomes') def get_incomes(): schema = IncomeSchema(many=True) incomes = schema.dump( filter(lambda t: t.type == TransactionType.INCOME, transactions) ) return jsonify(incomes.data) @app.route('/incomes', methods=['POST']) def add_income(): income = IncomeSchema().load(request.get_json()) transactions.append(income.data) return "", 204 @app.route('/expenses') def get_expenses(): schema = ExpenseSchema(many=True) expenses = schema.dump( filter(lambda t: t.type == TransactionType.EXPENSE, transactions) ) return jsonify(expenses.data) @app.route('/expenses', methods=['POST']) def add_expense(): expense = ExpenseSchema().load(request.get_json()) transactions.append(expense.data) return "", 204 if __name__ == "__main__": app.run()
The new version that we just implemented starts by redefining the
incomes variable into a list of
Expenses and
Incomes, now called
transactions. Besides that, we have also changed the implementation of both methods that deal with incomes. For the endpoint used to retrieve incomes, we defined an instance of
IncomeSchema to produce JSON representation of incomes. We also used
filter to extract incomes only from the
transactions list. In the end we send the array of JSON incomes back to users.
The endpoint responsible for accepting new incomes was also refactored. The change on this endpoint was the addition of
IncomeSchema to load an instance of
Income based on the JSON data sent by the user. As the
transactions list deals with instances of
Transaction and its subclasses, we just added the new
Income in that list.
The other two endpoints responsible for dealing with expenses,
get_expenses and
add_expense, are almost copies of their
income counterparts. The differences are:
- instead of dealing with instances of
Income, we deal with instances of
Expenseto accept new expenses,
- and instead of filtering by
TransactionType.INCOMEwe filter by
TransactionType.EXPENSE, to send expenses back to the user.
This finishes the implementation of our API. If we run our Flask application now, we will be able to interact with the endpoints, as shown here:
# start the application ./bootstrap.sh & # get expenses curl # add a new expense curl -X POST -H "Content-Type: application/json" -d '{ "amount": 20, "description": "lottery ticket" }' # get incomes curl # add a new income curl -X POST -H "Content-Type: application/json" -d '{ "amount": 300.0, "description": "loan payment" }'
Dockerizing Flask Applications
As we are planning to eventually release our API in the cloud, we are going to create a
Dockerfile to describe what is needed to run the application on a Docker container. We need to install Docker on our development machine to test and run dockerized instances of our project. Defining a Docker recipe (
Dockerfile) will help us run the API on different environments. That is, in the future, we will also install Docker and run our program on environments like production and staging.
Let's create the
Dockerfile in the root directory of our project with the following code:
# Using lightweight alpine image FROM python:3.6-alpine # Installing packages RUN apk update RUN pip install --no-cache-dir pipenv # Defining working directory and adding source code WORKDIR /usr/src/app COPY Pipfile Pipfile.lock bootstrap.sh ./ COPY cashman ./cashman # Install API dependencies RUN pipenv install # Start app EXPOSE 5000 ENTRYPOINT ["/usr/src/app/bootstrap.sh"]
The first item in the recipe defines that we are going to create our Docker container based on the default Python 3 Docker image. After that, we update APK and install
pipenv. Having
pipenv, we define the working directory that we will use in the image, and we copy the code needed to bootstrap and run the application. In the fourth step, we use
pipenv to install all our Python dependencies. Lastly, we define that our image will communicate through port
5000 and that this image, when executed, needs to run the
bootstrap.sh script to start Flask.
To create and run a Docker container based on the
Dockerfile that we created, we can execute the following commands:
# build the image docker build -t cashman . # run a new docker container named cashman docker run --name cashman \ -d -p 5000:5000 \ cashman # fetch incomes from the dockerized instance curl
The
Dockerfile is simple but effective, and using it is similarly easy. With these commands and this
Dockerfile, we can run as many instances of our API as we need with no trouble. It's just a matter of defining another port on the host, or even another host.
Securing Python APIs with Auth0
Securing Python
For example, to secure Python APIs written with Flask, we can simply create a
requires_auth decorator:
# Format error response and append
In this article we learned about the basic components needed to develop a well structured Flask application. We took a look on how to use
pipenv to manage the dependencies of our API. After that, we installed and used Flask and Marshmallow to create endpoints capable of receiving and sending JSON responses. In the end we also took a look at how to dockerize the API, which will facilitate the release of the application to the cloud.
Although well structured, our API is not that useful yet. Among the things that we can improve, we are going to cover the following topics in the next article:
- Database persistence with SQLAlchemy
- Global Exception Handling
- Internationalization (i18n)
- Security with JWTs

Review Request: perl-HTML-TableExtract
Last modified: 2014-03-16 22:59:15 EDT
Spec Name or Url:
SRPM Name or Url:
Description: A perl module that extracts tables. Needed for perl-Finance-Quote.
I can get started with the specfile, but the review process requires an SRPM
instead of one that's been built. Could you send one along?
Package builds fine in mock and rpmlint is silent.
Issues:
Can't check a couple of things due to lack of SRPM.
%description seems to be from another package.
Review:
* package meets naming and packaging guidelines.
X specfile is properly named, is cleanly written, uses macros consistently and
conforms to the Perl template. However, the description seems to be the one
from the perl-Finance-Quote package.
* license field matches the actual license.
* license is open source-compatible. It's not included separately in the
package, but this is not necessary as the upstream tarball does not include it.
X can't check whether source file matches upstream without SRPM.
* package builds in mock.
* BuildRequires are proper.
* no shared libraries are present.
* package is not relocatable.
* owns the directory it creates.
* no duplicates in %files.
* file permissions are appropriate.
* %clean is present.
* code, not content.
* documentation is small, so no -docs subpackage is necessary.
* %docs are not necessary for the proper functioning of the package.
* no headers.
* no pkgconfig files.
* no libtool .la droppings.
* not a GUI app.
* The package owns %{perl_vendorlib}/HTML, which will probably also be owned by
any module under the HTML:: namespace. However, there are no dependencies which
could create this directory so there is no alternative but for this package to
own it.
Heh, I uploaded the wrong RPM. SRPM there now, with fixed description and
license tag.
Cool.
* Source matches upstream:
ad3ddfb3e25826071d1e52e336862438 HTML-TableExtract-2.07.tar.gz
ad3ddfb3e25826071d1e52e336862438 HTML-TableExtract-2.07.tar.gz-srpm
Description looks good.
APPROVED
Please add additional buildreqs:
perl(HTML::TreeBuilder)
perl(Test::Pod)
perl(Test::Pod::Coverage)
All are available in Extras and will provide additional test coverage.
Yuk, so I have to have 7 random perl modules around just to run a test suite
that doesn't affect the actual build output?
Note that the HTML tests actually require HTML::ElementTable on top of
TreeBuilder, and that's not in Extras, so adding the req doesn't help there.
(In reply to comment #6)
> Yuk, so I have to have 7 random perl modules around just to run a test suite
> that doesn't affect the actual build output?
It would affect the build output if one of the tests failed, which might happen
for instance when the package came to be built on an architecture you can't test
yourself.
The modules concerned are all available in Extras so there's no real hardship in
installing them, and if you don't want them around on a long-term basis you
could always "rpm -e" them afterwards. Better still, you could do test builds in
mock and then those modules would never need to be installed on your system at all.
Most of the perl module packages I've come across in Extras have buildreqs for
all modules used in their test suites that are available in Core or Extras,
> Note that the HTML tests actually require HTML::ElementTable on top of

That's why I didn't ask you to include that one as a buildreq :-) Unless you'd
like to package that one too...
Added, -2 uploaded.
This package is already approved; you can check it in at your leisure.
This bug should be closed NEXTRELEASE if the package was checked in and the
builds succeeded.
Built.

Preliminary note: a transport request dependency check will soon be included in SAP standard! See announcement here (in one of the last comments) :{8F263B5D-1FAB-4942-BB73-AB8404180F68}
In earlier publications I explained I was developing a transport request dependency analyzer (also known as TRS: transport request sequencer). It’s a program that helps me find the correct release order of my transport requests to avoid errors during import into target systems. See:
Part I: How-to store dependencies between transport requests
Part II: On my way to resolve transport request dependencies
I used to publish versions of this program on code exchange… but as it is now closed, you’ll find the file you need to install it attached to this blog post (don’t forget to remove the extension “.txt” at the end of the file: I had to add it because SCN doesn’t allow to upload “.zip” files). Select the file you need depending on the import method you choose (transport request vs SAPlink), and the version of your system :
– cofile&data_TRDA_NW702_5.50.zip : contains one transport request relevant for NW702 upward
– cofile&data_TRDA_NW700_5.41.zip : contains one transport request relevant for versions older than NW702
– NUGG_TRDA_NW700_5.4.nugg : nugget file for NW702 upward
Also, if you choose to import the program via transport request, you can check that everything works fine thanks to the ABAP Unit test class that is included. All you have to do is to:
– Start tcode SE38 and execute program SAPRSEUT: this is a standard program that will update some table indexes that are necessary for TRDA to function correctly (more information available here: Note 18023 – Jobs EU_INIT, EU_REORG, EU_PUT).
– Start tcode SAUNIT_CLIENT_SETUP and make sure limit of risk level is set to HIGH.
– Now start tcode SE80, select class ZCL_TRDA_SEQUENCER, right click on test >> Unit test. This will create a few transport requests in your system (hence the risk level HIGH) and try to find the dependencies between them.
If no error is thrown, TRDA is ready to go!
Now, to use TRDA, start program ZCEX_TRDA_START : you will get the same selection screen as the one that appears via tcode SE03 / Find requests:
Default values should be OK 99% of the time. Execute to get a list of transport requests matching the criteria of the selection screen, and access TRDA functions:
Here you may select one or more lines, and start the dependency analysis by clicking on “Sequence” button. The system will check every object of the corresponding requests, and try to find referenced objects belonging to other transport requests that are still unreleased. Important to know:
- Only ‘Z’ objects are decomposed, because it would take too much time to check every SAP standard object… so in case you implemented an OSS note for example, no dependency will be found.
- Only unreleased transport requests are analyzed because we assume released TR were (or will be) successfully imported into target systems.
When the dependency check is complete, the system displays the computed sequence (first rows need to be released/imported first):
You can click on the “Explain” button to display a popup which gives you more information about the dependencies that were actually found. In the example above, transport request 900036 was listed as a predecessor of 900038 because the later includes object ZCEX_TRS_DEPENDENCY_LOG_T, which references structure ZCEX_TRS_DEPENDENCY_LOG… and this structure is included in TR 900036:
It may also happen that a “circular” dependency is found… if A needs B which needs A. In that case, you will see “CIRC” in the info column:
That’s where the “Merge” button comes into play: you can select two or more requests, and merge them…
I guess this is a tool useful for those (like me) tired of return codes 8 because of missing objects during transport… And for more information, see the latest news here: STMS: facing errors when importing transport requests? It’s your fault!
Thank you for posting your blog series on this topic, it looks very interesting, I will have a closer look when time allows.
The name “sequencer” did lead me in the wrong direction though, I initially thought you built some sort of “overtake check”, making sure that newer versions of objects are not imported before older versions, whereas your check is about dependencies to other bespoke objects before release.
Thomas
Hello Thomas,
Thanks for your feedback. I agree that the name “sequencer” could be misleading… so I tried to find another title for this blog: “transport request dependency analyzer”. I hope it will give a better feeling of what this tool is about.
Cheers,
Nicolas.
One important remark:
Import the nugg file into package ZCEX_TRDA.
Otherwise, later import of the separate CR (version 4.2) may lead to serious errors.
Hi Shai,
Thanks for mentioning this point. Indeed I decided not to use SAPLINK for new versions of the transport request denpendencies analyzer, as I was facing some issues with the tool… Sorry about that. So in the near future I plan to remove SAPLINK nuggets from the available releases to avoid any inconvenience.
Regards,
Nicolas.
Hi Nicolas,
Just out of curiosity, what were the SAPLink issues you had to face with?
P.S.
I would use this opportunity to thank you for sharing this interesting and useful tool.
You’re welcome!
Issues faced with SAPLink:
1) No stable released with “Package” plugin… hence I had to change the signature of a bunch of methods manually to transport ZCEX_TRDA development class (but still I faced some issues as most objects were created as LOCAL objects).
2) No plugin for Breakpoint group.
3) No plugin for user parameters.
4) Impossible to import objects from a dedicated namespace (namely /CEX/) into a customer system
Etc.
Hence I realized that using transport cofile&data files would be the easiest way to go…
Cheers,
Nicolas.
Hi,
I’ve been playing a little with your tool.
I saw that when the dependent object has no CR in versions (method ZCL_TRDA_SEQUENCER->GET_TRS_REQUEST_ID), you use the author instead.
This might be little confusing.
What is the purpose of it?
Hi Shai,
That’s to handle the case where you create one object, but delete it manually from the corresponding TR afterwards. In this case I think no TR will be shown in versions, but still this object might show up in the dependency log and I didn’t find it user friendly to have an empty TR number… at least the user who created this object will give you a clue who you need to ask for clarifications.
Also, it’s useful to address dependencies with SAP standard objects for which you have no TR in versions.
Anyway, if you limit the dependency analysis to Modifable requests (which is the primary purpose of the tool), and you do not mess up with your TR, I believe you should always see identification numbers, no authors.
Regards,
Hi Nicolas,
So in my current organization, the majority of transport issues are due to improper sequencing across systems.
For instance:
1) transport A goes from DEV to QA
2) transport B is created and is dependent on transport A
3) transport B goes from DEV to QA
4) transport B goes to PROD before transport A and fails
To deal with this, I can see a nice expansion to the tool wherein existence-checks for each related transport are made to each system in the landscape (via RFC, select-options on the selscr for destinations) and reported back to the ALV with a column per system, nice red X and green checkmark icons, something like that.
Do you think this is a feasible addition?
One issue that comes to mind immediately is the one that we just dealt with where including released transports for a particular transport resulted in page file overflows.
To mitigate this, perhaps an option can be included to load objects/sub-objects for related released transports that aren’t in PROD (i.e. transports that can pose the risk of import failure). As well, perhaps a ceiling on the number of transports, a check on the page file utilization (dynamic but getting fancy), or a date range for release dates (less preferred since you could have old transports lingering out there theoretically).
Let me know what you think.
Thanks,
Chris
Hi Chris,
Regarding your first comment, for sure that’s something feasible… but I won’t develop it myself because I believe there should be no difference in the TR sequence between QA and PROD. If you change the sequence it should be at your own risk: I’m convinced that no tool will be bullet proof enough to assure that everything will work as intended in the target system 100% of the time.
That’s the beauty of code exchange: you can download a program that suits 80% of your needs, and add the missing 20% yourself
And regarding your second point (memory shortage), did you try to start an analysis on all transport requests after the OSS note I sent you was implemented? Because if you’re still facing the same issue, then I can add a check to limit the number of TR that are being analyzed… but adding an option to include objects that aren’t in prod could be error prone. Imagine that you create a table ZMYTAB and transport it to prod. Then you add one new field to this table, and this field is used by a function module included in the request being analyzed: although ZMYTAB is already in PROD, you need to transport its modification beforehand…
Cheers,
Thanks, I’m going to look into this soon.
We had a series of OSS notes to apply after a kernel upgrade so that I could use SU3 again to set the parameter without dumping. I’ve set the parameter and re-tested, the page file overflows are still happening.
The bulk of the memory is tied up downstream of FM REPOSITORY_ENVIRONMENT_ALL. I’ve taken a look at the EXPORT memory is never re-imported in
the life of the session so I’m currently experimenting with freeing each new memory ID after every FM call. I’ll let you know how it goes.
Chris
Hi Chris,
Thanks for the feedback.
And as a matter of fact, I think it is a good idea to be able to limit the number of transport requests to analyze. So I’ve just published version 4.3 of the program which will check user parameter ZCEX_TRDA_MAX_TR. If this parameter is not set, the program will stop processing after 100 TR analyzed. You can set this parameter to increase or decrease this limitation…
And be aware that in case max number is reached, transport order release will be deactivated as we cannot be sure that all dependencies were found…
Regards,
Hi Chris,
For the matter of fact, these are some of the problems we also face with.
Another point: As you have mentioned in later message, when analyzing all the CR (includes modifiable ones), CR which have been imported to the PROD system already should be out of scope.
I was planning to enhance this functionality in our system next week: Adding an additional column of current/last SAP system to the report and also excluding PROD CR from the analysis (according to selection screen parameter).
As we’ve already implemented a similar functionality in other tool, it shouldn’t be too complicated.
I would share my code changes as soon as I finish them.
Regards,
Shai
Hi Chris and Shai,
I’m glad you want to help. Let’s join TRDA project then, and continue this discussion on SAP code exchange workspace. If you definitely think this add-on would be useful, I’ll help you implement it in a future release.
Cheers,
Hi Everybody,
Does anybody tried to use it with an ECC 7.0 ? Is any chance to do it?
Regards
Mariusz
Hi Mariusz,
Indeed you’ll have to make some adjustments to make it work on SAP Netweaver < 702.
What you can do is the following: join the project and open a discussion thread with the issues you are facing. I’ll do my best to help you fix them.
Regards,
Nicolas.
Hi Mariusz,
Thanks for joining the project and opening a discussion. I’ve been working on it, but as you’re not answering my messages, make sure you activated email notifications if you still want to proceed further =)
Cheers,
Nicolas.
I’ve many bespoke tools of this type over the years but yours looks to be one of the better ones.
Hi Mike,
Thank you very much for the nice feedback. If you had the opportunity to install and test the transport request dependencies analyzer, I’d be very interested to know if you ever faced situations where this tool didn’t compute the right sequence. If so, do not hesitate to open a discussion thread on code exchange.
Also, be aware that I will release a version backported to older sap_basis level within a couple of days.
Cheers,
Nicolas.
Hi Nicolas – Thanks for sharing this code. I developed a similar tool for use on one of my previous projects which turned to be very useful.
However, there is another way to manage SAP transports. If interested, see this article in SAP Experts, which I wrote some time ago:
Hi Narendra,
Sorry but I don’t have access to the article you wrote: seems like I need to pay some fee… which is exactly what I didn’t want to do when publishing my code on SAP Code Exchange. On the contrary, I want any people interested in this program to be able to download it, play with it, suggest improvements, etc.
Nice Tips. Thanks!
Hi Steve,
Thanks for the kind words.
Cheers,
Nick.
Hi Nicolas!!
I’ve read your article and sounds very nice your tool, however, I can’t download it.
I’m facing A LOOOOOOOT of problems with the transports.
Could you please tel me another option to download you tool?
best regards!!
Hello Adrian,
Sorry about that but indeed SAP Code Exchange is not very intuitive… And maybe I need to approve your membership request before you can download the files — what I just did.
So please try again to connect and send me a private message to tell me how it goes.
Cheers
Nicolas.
Hi Nicolas,
Really a great work nicolas, i am willing to try it but when i click on the link for program it takes me to the Code exchange.but from then i am not able to proceed.i am able to see documents and release notes but could not make out more.Could you please help me out with steps to proceed from begining.Sorry for troubling.
Your reply would be so helpful.
Thanks,
Dinesh.
Hello Dinesh,
No problem. I’ll be glad to help. I sent you a direct message on code Exchange.
Cheers,
Nicolas
Hi Nicolas,
Your program sounds really helpful. However, the link doesn’t work for me either. Can you please send me the link too..
Thanks
Vishal
Hi Vishal,
I’m sorry about that but indeed SAP decided to shut down SAP Code Exchange as of the 31th of August 2013… and I didn’t have time to transfer everything on another platform like Github for example. So meanwhile I added the direct download links to my own website:
But be aware that I’m in the process of publishing a new version where you’ll be able to filter transport requests by date, switch between a list / tree ALV layout, etc. Stay tuned!
Cheers,
Nicolas.
Dear Nicolas,
Very good Article
Thanks for sharing !!!
Hi Nicolas,
This is so good to see you shared the transport sequencer and seriously it is needed to be implemented so as to move the transport requests appropriately without errors as you said it is not possible to find the dependencies of the objects to be transported.
Thanks,
Ankita
Hi Nicolas
When I run ZSAPLINK to upload the NUGG file, I got the error messages said:”missing plugins checking point, user parameters, and MSAG”
Hello Nicolas,
I’ve notice this post is from 2012. I’ve search for the standard solution SAP said would provide but I can’t find anything. Do you know if is it already available?
Thanks a lot!! Great post by the way!

Hello Frinée,
SAP delivered the following functionality:
Import Queue Web UI – Performing Import Checks – CTS Plug-In – SAP Library
I think you need to install a component called “CTS-Plugin” into your Solution Manager to make it work: but as this is not a system I’m familiar with, I must admit I never gave it a try. Also: I’ve been using TRDA for some years now and it’s giving very good results, so I can’t remember last time I faced a CR8 when importing something to QA 🙂
Cheers,
Nick
Maybe it’s a good chance to edit your “Preliminary note” in the original post?
Hi Nicolas, I have been facing some issues with the transport sequencing recently due to a huge project where same objects are being modified by multiple developers and thus creating a mess in production. I was searching for transport sequencer and came across your post. Reading all good feedback makes me very hopeful that this tool can help me. However I face issues downloading it. I can not get the data and cofiles for the attachment. Please help me get the files. Thanks and Best Regards, Priti
Hi Priti,
In fact it is not possible to attach zip files to SCN blog posts. So I renamed my files xxx.zip.txt. Also: when you upload files on SCN, the system will automatically compress it… and we end up with something like xxx.zip.txt.zip. So here is what you need to do:
1) download xxx.zip.txt.zip on your laptop
2) extract the file somewhere.
3) rename the extracted file xxx.zip.txt to xxx.zip
=> if you now open xxx.zip you’ll get what you’re looking for.
Best regards,
Nicolas.
Hi Nicolas,
Thanks. I was doing the same thing earlier. But found out that my laptop had issues with my rights.
So i downloaded the file on another laptop with a user of admin rights and i was able to change the extension.
Now i will test the transport sequencer, I am very hopeful. I will let you know if that worked for me.
many thanks,
Priti
Thanks for your useful document sharing.
Regards.
Nicolas, I am unable to access your link for the file download. Your website url does not resolve. Can you provide me with another link?
Thanks.
Hi Nicolas,
I am unable to access your link for the file download.
Can you please provide me with another link?
Thanks.
Hi Nicolas,
Can you please provide the link for the files.
Thanks,
Shruthi
Hi Guys,
Anybody can share with me the files using my personal email lblbab17@gmail.com?
Nicolas seems very busy with other things.
Thanks a lot in advance
Lahcen
Great Articles and excellent works.
However the link missed and the another link on the comment seems also failed.
It will be great appreciated if source code recovered.(github or anything..else will be great)
Dear Nicolas,
Thank you for sharing your solution with these set of blogs.
However I’m missing the attachments in it. Would it be possible to share the codes once again?
Thank you in advanced.
Hello David and everybody,
I’m sorry but there seems to be something broken on SCN since the last migration: I don’t receive any notification on comments on my blog posts, and I can’t even edit them… So all I can do is adding a new comment to let you know that SAP has finally published an oss note to provide the same kind of program as standard. See:
Hope that helps.
NIcolas.
Hello,
Is it possible to have your program as well?
kind regards
Hello Sylvain,
You’ll find everything you need if you install the following OSS note:

Author: Les Cottrell. Created: April 19
This was held at the Institute of Pure and Applied Mathematics at UCLA. There were about 75 attendees. Walt Willinger was the chair-person. Paul Barford of U Wisconsin gave a talk to set the stage.,,
Need to attack the wizard gap between the experts who can debug/tune TCP to get maximum performance and what the non-expert can get. Much of the difficulty of addressing this is the transparency of TCP. So have developed an instrumented TCP stack where one can dynamically read and set variables in the stack. Want to make this an IETF standard and get vendors to implement.
They have implemented 5 groups of variables. Stages of impact of Web100: first round reduce stack bottleneck, indirectly fix paths, indirectly fix applications; second round change user notion of "big" and raise loads everywhere.
Pathprobe is pre-alpha tool to rest and diagnose paths, currently under rapid prototyping, a joint effort of Web100 & Net100 mixed NSF & DoE funding. Measure all model parameters for Rate=MSS*0.7/(RTT*sqrt(loss)), and the model should agree with the actual performance. Do all parameters agree with expected values, excessive RTT suggests bad routing. Test from web100 sender to any TCP discard server, scans different windows gives data rate, run length (transmit pkts/recoveries) & RTT. One signature for reorders is a large number of dup acks and no retrans. Pass/fail statuses greatly eases non-expert interpretation, is there sufficient data, window clamp too small, path is too lossy so failed, path met rate but too lossy for longer link. Want to sectionalize a long path S->R by testing A>B, A>C, A>D etc, each section has to run at the target data rate and meet model parameters for S>R. Pathprobe is likely to be the web100 killer app, pushes Web100 out to needy users, collect interesting pathological paths, prove the instruments in the TCP MIB, the present is a fast moving target.
Development of network-aware operating systems. DoE funded at $1M/yr for 3 years. Measure & understand e2e net & app performance, tune app (grid & bulk transfer). Components: leverage web100, network tool analysis framework (NTAF), tool design & analysis, active net probes and sensors, network metrics dB, transport protocol analysis, tuning daemon to tune network tools based on findings. Web100 is based on Linux 2.4with 100+ variables per flow. Net100 add web100 to iperf, java applet (see) . Working on daemon that (WAD) will tune a network unaware application, work around net problems, query dB & calculate optimum TCP parameters. Version 0 WAD for ORNL to NERSC showed no tuning gets <10Mbits/s, hand tuned get up to 70Mbits/s, WAD got 60MBits/s. Use NetLogger to log derived events, now working on tuning parallel streams. Looking at ways to get WADs to communicate between each other. Need to try and avoid losses (choose right buffer size, ECN, TCP Vegas, reduce bursts), faster recovery from losses (bigger (jumbo) frames), speculative reocveriry (D-SACK), modified congestion avoidance (AIMD), TCP Westwood), autotune (WAD buffer sizes, dupthresh, Del ACK, Nagle, aggressive AIMD, virtual MSS (e.g. add k segments per RTT rather than 1 MSS per RTT), initial window, ssthresh, apply to only to designated flows/paths, non TCP solutions (rate based, ?).
Have Net100 probes at ORNL, PSC, NCAR, LBL, NERSC, preliminary schema for network data, injitial web100 sensor daemon & tuning daemons, integration of Wu Feng's DRS (Dynamic Right Sizing) & web100. In progress TCP: tuning extensions to Linux/Web100 kernel, analysis of TCP tuning options, deriving tuning info from network measurements, tuning parallel flows and gridFTP. Future interactions with other network measurement sources, multipath/parallel selection.
Want to look at real jumbo frames, ECN (supported by Linux, instrumented by web100), drop tail vs RED, SNMP path data where are losses occurring, what kind of losses, SNMP mirrors (MRTG).
Allows easy configuration and launch network tools (iperf, pchar, pipechar, will add pathrate & pathload, netest and host stuff), augment tools to report Web100 data. Collect & transform tool results into a common format. Archive results and save for later analysis, all tools are instrumented with Web100. Want to compare iperf with application, determine advantage of parallel data streams, analyze variability over time, compare tools. Have archive in place in SQL. Working on XML format, also support NetLogger format. Will be tied into the GMA publish/subscribe mechanisms. Have analysis form, select time frame, application and way to report on. Have 5 sites with full mesh. Also provide access to ascii data. Can look at data with NLV interactively allows looking at Web100 variables, with data for 1/sec.
NTAF issues? reliabilities, tools hang or crash, need management thred/tool to timeout, need non-blocking I/O, servers hang or crash (use cron to restart), archive dB performance, SQL table design, buffering issues (pipelining to guarantee that applications & sensors never block when writing to archive), fault tolerance with redundant archive destinations.
10 clients each transferring 10MB/s=6200 ev/s 313 KB/s (1.1.GB/hr).
Pipechar tool to measure hop-by-hop capacity and congestion through the network. Faster than pchar, pathrate, more accurate on fast networks, not always accurate still refining the algorithms, results affected by host speeds, client side only, 100kbits/s load. Uses UDP/ICMP packets of various sizes and TTL, uses packet trains assumes dispersion is inversely proportional to available bandwidth. In general pretty accurate.
Netest is a new tool, to provide non wizards with enough information to know what to expect, active client/server tool, puts fairly heavy load on net about 5Mbps for 1-2 mins but faster bursts. Gives single/multi stream UDP throughputs, then does TCP to give optimal window size, single stream throughput, makes recommendation on number of streams.
Have a self configuring network monitoring project, leverages passive Bro project to monitor traffic to characterize application streams as they cross the network. Use passive optical taps. Need fast cpus, tricks with GE drivers, recommend Syskonnect cards, add time stamps in driver code. Synchronize via NTP. Use interrupt coalescing. Install monitor hosts at critical points in the network (i.e. next to key routers), passively capture packet headers of monitored traffic, configured & activated by application end hosts (i.e. like remotely activated tcpdump), can only monitor own traffic. Have 2 boxes at the moment (NERSC & LBL), adding third at ORNL. No results yet. Contact Craig Leres or Brian if want to build own box. Need a writeup.
Web based tool based on ORNL applets, modified analysis, also modified NLANR iperf support 2 new options (-ee, -R) print web100 derived details and get receiver stats too. Tool is web based runs on any client with java enabled web browserr. ID what is happening, cannot tell if a 3rd party is performing properly, it is only end-to-end, can't tell you where the problem is, only relevant for particular ends. Sends 10 sec data from client to server. Then 10 sec in reverse prints out summary of link speed and whether duplex is full or half . Allows one to get more details with a statistics button for snd/rcv throughput, details for 5 configuration tests (link speed, duplex, congestion, excessive errors, duplex mismatch). throughput limits section (%S-R-N limited RTT % loss, % out of order, tweakable settings (Nagle, SACK etc.) Plus more details individual TCP counters collected by web100, conditional test parms, theoretical limits analysis bw*delay, loss rate, buffer sizes, server logs all counter variable used for condition tests.
Current development have 3 servers at ANL (450MHz P3s), servers support both web based tool and modified iperf based tools. Looking for people who might be interested in tool.
Demonstration of web tool running for 10 secs () showing the two end throughputs, then showed the statistical analysis, also showed all the web100 variables. Looks for cwndtime >30%, maxssthresh >0, PktsRetrans/sec > 2 ..., he claims this works quite reliably. Sees a lot of transitions between sender limited and receiver limited states.
Future 4th servers at ANL for external users, explore GE Ethernet issues, explore wireless, talking with Tom DeFanti for Starlight, Starlight partners/collaborators.
Caveats: server needs time between tests (~90secs), if try for 2 machines simultaneously then 1st succeeds seconds waits or fails. Analysis messages need to be validated.
Update in program, new developments: early career PI in applied ($100K in 3 years) mathematics, CS & net research, applications due in next week, expect large number of profs in Us in early stages of career. Coming workshops: LSN on cyber security and info assurance (joint agencies) for next generation cyber sec. LSN sponsored workshop on NG transport protocols (where is TCP going, is there a new protocol needed). ESSC/I2 joint tech meeting in planning (at Boulder week end July/begin August); joint ESCC/net research PIs meeting in planning. Meeting in January of I2 joint techs in Miami will be co-scheduled with ESCC. This joint focus is to allow ESnet to focus on research & leading edge applications that cannot be done elsewhere. Ongoing research: hi-perf transport protocols, network measurement and analysis, cyber security. Program growth opportunities include Tbps optical networking, distributed cyber security, terascale storage and file systems.
Challenges are e2e (end-to-end) performance, network aware applications, scalable cyber-security. Want to provide high performance to applications with current & future networks. R&D for ultra high speed nets. Near term enhance existing network protocols to operate at high speed, e2e perf measurement & analysis, develop new advanced network services. Long term harness abundant optical bandwidth, develop optical protocols. E2e communities are ESnet, I2, international communities. This means have to manage inter network domain issues. Objective is high throughput & advanced networking capabilities to enable distributed high end apps. Partners are ESnet application communities, network research/middleware, site networking group, I2 & international collaborators, The approach is net measure and analysis research, net measure & analysis infrastructure, net measure & analysis toolkits, coordination of e2e at various sites, net performance portals. New call proposals for a performance program, coinciding with the termination of the current 3 year cycle SciDAC projects. It will need to move into a space that is innovative.
Major focus today: TCP enhancements (30, net storage (1), grid security (1).
Components of E2E performance: net ware apps, SANs & storage performance issues; host issues TCP, NIC & MTU, OS & I/O; core: routing, traffic eng ...
Want to make application aware of host and network aware (ie. tie together) by end of 2003. By 2005 want coupling all to be transparent.
Network measurement infrastructure (NMI) proposed NIMI based measurement platforms deployed at each site (SLAC, ANL, ORNL, CERN, UMich). Need to coordinate measurements, have all measurements colocated in a single platform and schedule, run as needed and then make available to all who need. Also want to isolate whether problem is at SLAC, CERN in Abilenbe, GEANT, ESnet, IXPs etc. So want boxes placed at exchange points to diagnose along path. NIMI not funded adequately, needs to refund so can put most of tools in that infrastructure, also hope ESnet to deploy in their infrastructure. Thomas wants the NIMI structure to be developed and made operational, then up to each lab to procure and maintain etc. Wants to set up an E2E perf group in ESnet so can do between labs and link to I2 E2Epi.
TCP futures: TCP works everywhere, so need to work on enhancing TCP with a unified implementation, enhance existing TCP implementations, idea is to derive classes of TCP for different transport media etc.. In parallel for further into future, develop a new TCP an Internet based transport with all-optical fiber. Talking about overlay networks between big science centers. Solve problem in community that needs higher speeds (HENP, ESnet, NASA), then take to IETF for standardization. Different classes come from a generic implementation of TCP from which is generated Reno, wireless, Tbits/s, Vegas version etc. Hard otherwise to cover emails or web pages for seconds versus file transfers lasting for days.
Talked about optical burst switching. For very high throughputs allow to move bursts in sizes of 64kbytes, 2GB, 4GB.Use forward error connection. In addition have a secondary channel with just in time scheduling to set up the transfer. Protocol has been designed, NSA and DARPA taking lead on this. SGI working on. DoE are being asked for testing for large transfers. Wants to set up a n optical burst switching testbed.
Then went on to show overlay network which provides depots to move data e.g. from CERN to Sunnyvale allowing access from west coast sites over slower links using TCP. This enables high speed core with optical burst switching and lower speed edge connections.
Program opportunities: Ultra high speed data transfer protocols (this would sit well when going to congress to get money). Distributed cyber security for large scale collaboration. High performance WAN file storage/systems.
StarTap was a single ATM exchange point to connect international links to. But nobody was willing to pull to coasts. It did enable transfer traffic (e.g. Europe to Japan). Has 15 connections. StarTap funding is running out after 5 years. StarLight = StarTap - NG. Have now a production 1Gbpos interchange at Chicago, looking at OC48 (2.5Gbps) and OC192 (10Gbps). Located at Northwestern so vendor neutral. Access to carrier POP has been a major headache with StarTap. Could not find a carrier hotel that was suitable (i.e. had all the carriers coming into). ANL does engineering and brainy stuff. Space is replacing a being decommissioned PBX. Currently present: Ameritech, AT&T, QWest, Global crossing (expect someone else will buy out services), Teleglobe. Policy free 802.1q VLANs are created between peering partners. Starlight benefits connecting networks: hi speed peering with large MTU, available colo, believe in multicast support. Equipment is a Cisco 6509 with lots of GE ports, Juniper M10 & M5 with GE and OC12, Cisco LS1010 with OC-12, ESnet IPv6 router, data mining cluster with GE NICS, Surfnet's Cisco GSR 120000 & 15454. Two OC12's between Startap and Starlight. ESnet and NASA both are located (now) at Starlight. vBNS still at Startap. Also have connection to QWest POP at 455 N. CityFront Park where Teragrid, NREN, ESnet, Abilene, IWire show up. Have 36 strands between QWest and Starlight. Hope this summer to upgrade the link between QWest and Starlight by using DWDM at 64 channels, they have the DWDM gear. 10 Gbps transfer service. GE is easy and simple. SURFnet has research project with Cisco between AMS & CHI with 15454 on each ends want to drive to do interesting things. Also CERN & UK interested in joining in. Want to research into what applications could, want to take advantage of such a setup.
NSF TeraGrid facility awarded by NSF to put distributed computers center iin place between ANL, SDSC, & NCSA. 40Gbps between QWest PoP between LA & Chicago. Problem has been to get it to the end sites. Goal is to get in place by June, expect ANL to QWest & NCSA in May. In September iGrid in Amsterdam in September 24-26. Looking for applications that can use more than OC48 (2.5Gbps) and 10 Gbps. Will be at Amsterdam Science Center (same location as Amsterdam Exchange point). Easier than connecting up a convention center. Need to tell in next 60 days what is needed.
Users voluntarily mark their traffic to be "nice", i.e. back-off in case of competition. SLAC traffic is heavily bulk throughput. Used I2 recipes for QBSS. Three test beds: 10Mbps bottleneck, 100Mbps and 2Gbps. Show plots of how quick QBSS backs off and restores, also aggregate throughput is maintained.
Goal: enable researchers faculty to obtain high performance from the network. Four initiative focii are applications, host OS/tuning, measurement infrastructure, performance improvement environment. Role of Internet2 capitalize on existing work and bring people together. Want to disambiguate where the problems lie. Instrumentation options has goal of heterogeneous instruments. Quilt allows measurements to be made from places across the network with archived data, e.g.. Use existing machines where possible (AMP, Surveyor), beacons (H.323,FTP), packet reflector. Packet reflector with agents at various sites to allow packets to be sent & reflected. Want access to standard operational information from key places along the path. Need end-to-end analyzer to put data together and interpret. Matt can get 3 sec interval loss data for Abilene. Matt is measurement czar for SC2002 show floor network.
Aside form Bill Wing, in future there will be much closer collaboration between I2 & ESnet since much of data required by universities is from the DoE Labs.
Abilene upgrade will put GE switches in the rack connecting into router interfaces. Will be dedicated measurement machines, 1/4 space for worthy experiments, e.g. for 3-6 months projects. Hi bw flow tester, latency tester (think AMP/Surveyor/Skitter), CDMA on board, local measurement collector. A smattering of E2E performance initiative boxes Will provide SNMP, flow data, routing BGP & IGP conceptually circular buffer to hold interesting data.
Project funded by DoE. Want to provide trusted authentication across domains. Risk model is difficult to determine, protect but not interfere too much. Holy grail is single login across domains etc. The vulnerabilities are that PKI is a largely unproven technology (under-going development), compromised CA (improperly generated keys, improperly signed certificates; compromised key. Inadequate protection of private keys. Then need applications that improperly check assigned keys (e.g. check for revocation). Compromised of machine taht generate key pairs, generate certificates, sore private keys, verify authorization for loacl resource access, is it worse than current? No secure time source which is important for certificate expiration, effective revocation may be OK if no long term dependencies (e.g. signing).
Threats in HENP: have an active, adaptive opponent; unauthorized use of resources use of DDOS attacks (large net pipes), use for cracking keys; theft of capabilities (identity), destruction of data, public embarrassment (funding impact).
GSI says each site must implement mapping from grid account space (X.509 + proxy certificates) to local account namespace. Local account information remains at site. Requires a distributed grid database, grid repository maintains a list of trusted third parties to provide authentication services, sites may refer to grid repository and augment that list with their own trusted parties (not real time).
Delegate/proxy: reluctance in sending log-term (years) credentials across the Grid to repeatedly respond to authentication requests. Instead create short term possibly limited capability credentials (key-pair) signed by long-term credentials.
Community Authorization Service: many users have common level of authentication to group of resources, provide a single access ID to site for authorization, group the resources to reduce the auth/overhead. Have to reserve accountability, need protection from errors that destroy results, backtrack to a single user.
CAS overview gives a single GSI credential for whole community, pre-existing relationship with resource provider. CAS manages its own access control, access to resources it controls. User requests access from CAS.
New DWDM technoloy drivers: high peoered unidirectional amplification; Raman amplification, allows amplification on the way; wavelength add/drop optical muxes are appearing; higher TDM rates going from 10=>40 Gbps (but lose considerable number of DWDM channels, so may be no net gain, and need something capable of accepting 40Gbps; dynamic gain equalizing; high levels of FEC gives a few Db of gain. Today conventionally need regen at every 400Km. Between regens need optical amps (cheaper) and only need one for multiple wavelengths. Raman enhanced puts1200Km between regens (money is in regens). Ultra long haul DWDM exists but not deployed give 2000km expect 2003. Long enough to get between end-points without regens, still need amps every 50 km. Removal of regens saves30% of total cost.
Single fiber capacity going 80Gbps>120Gbps>150/300Gbps (i.e. 30 wavelengths). THen either got to more wavelenths (300/600) or C band (but new amps) (350/700), 2003-2004 0.7/17Tbps > 1.4/2.8 Tbps (C+L bans 25GHz) with Raman.
Different types of fiber. QWest picket in 1996 want to keep dispersion as flat a possible so don't get different velocities for different wavelengths. To help use dispersion compensators. But costly and increases losses so more amps. LEAF fibers have problems with edge channels and extra dispersion so fewer channels.
Two IP visions of transport: transport as dumb pipes on an unprotected lambda mesh with MPLS fast reroute on routers provides protection switching. Smart optical transport uses OXC over a lambda mesh provides protection switching, GMPLS running on smart OXC and router allows for dynamic provisioning.
High speed routers are taking a lot of power and power management is becoming needed, needs more A/C, needs bigger batteries, it is becoming a gating factor.
QWest have SONET rings with 10 wavelengths. Based on STS1 granularity (51 Mbit level or OC3). Moving to a lambda mesh which is more flexible using OC48 & OC192 lambda granularity. Use collector rings to get from customer to POP then use lambda mesh for backbone.
Roll your own network say for a 3 hub net: NY, CHI, LA. System could use existing design rules, Raman design rule, 2 fiber system. Terminals 10Gbps interfacing, no add/drop multiplexing. Costed such a model using Raman design rules, came up with $22M. Fiber $2K/mile = $12M. On 3K mile links need 50 ($800) amps which need colo ($480K), need terminals in CHI (2), NY & LA ($200K each = $800K). Amps $17K need 35, 11 regens ($250K), equip maint ($145K), fiber maint $150/mile, ops $500 for each of 50 colos. NRC $21.6M, recurring yearly $2.9M. Add wavelength costs $50K per TX/RX card (14, 5 regens and two ends with two for each location), i.e. $700K, plus maint $11.7K for 12 months, $140K. | http://www.slac.stanford.edu/grp/scs/trip/cottrell-escc-apr02.html | CC-MAIN-2016-26 | refinedweb | 3,625 | 57.77 |
The
Prism library updates
The major theme for the release is to move classes to Portable Class Library (PCL) and to address some of the requested CodePlex issues. In Prism for the Windows Runtime we moved the Event Aggregator to PCL. For this release we will move classes that support MVVM to PCL. For the classes that are moved to PCL, we will make the WPF versions obsolete.
Going forward you will see us put as much into PCL as is appropriate and reasonable.
Here is what we are doing for Prism in this release:
- ViewModel Locator: migrate ViewModelLocator from Prism for Windows Runtime to be a Portable Class Library and use it in Prism for WPF.
- BindableBase: migrate BindableBase from Prism for Windows Runtime to a Portable Class Library and use it in Prism for WPF. There is a request to add CallerMemberName to NotificationObject. We decided to port BindableBase from Prism for Windows Runtime to PCL as it already supports CallerMemberName. This means we will make NotificationObject obsolete in this version.
- Navigation: allow a dev to pass an object as a navigation parameter. This is a CodePlex request.
- InteractionRequest: migrate InteractionRequest to WPF. This is a CodePlex request.
- DelegateCommand: migrate DelegateCommand to a Portable Class Library. In a future release, Prism for the Windows Runtime will use the PCL version of the DelegateCommand.
Quickstarts
- Basic MVVM Quickstart.
- Create WPF version.
- Add ViewModel locator.
- Demonstrate how to construct parent-child Views and ViewModels.
- Demonstrate how to communicate between parent and child.
- State-based Navigation Quickstart.
- Create WPF version.
- UI Composition Quickstart.
- Create WPF version
- View-Switching Navigation
- Create WPF version
Drops & Release
Francis Cheung posted a drop today to CodePlex. Once we complete the release we will create NuGet packages and publish the source code on the Microsoft download center.
In this Drop
- Prism
- ViewModel Locator and Bindable Base ported to PCL
- NotificationObject is marked obsolete
- Interaction Request working for WPF
- Using .NET 4.5.1 and latest version of Unity and the Common Service Locator
- Navigation passes an object and a string
- ErrorsContainer, NotificationObject, CompositePresentionEvent marked as obsolete.
- Basic MVVM QuickStart using Prism ViewModel Locator.
- The ViewModel Locator uses a convention based approach to wire views and view models. In our XAML we tell the ViewModelLocator to AutoWire the view and the view model.
prism:ViewModelLocator.AutoWireViewModel="true"
- The convention assumes:
- View models are in the same assembly as the view types
- View models are in a .ViewModels child namespace
- Views are in a .Views child namespace,
- View model names correspond with view names and end with "ViewModel".
- For more information on how the ViewModel Locator works see the Prism for Windows Runtime documentation. We will provide documentation on how to modify the default convention.
- Prism, Stock Trader reference implementation, and Quickstarts updated to use BindableBase (Prism.Core) and PubSubEvent (Prism.PubSubEvents).
- CodePlex requests resolved
- 10110 – Unity not compatible with UnityExtensions
- 9439 – Navigation to an existing view
- 8121 – Prism ContentControl Region RequestNavigate – View already exists in region
- 9439 – [MEF] Navigation to an existing View
- 9118 – Extract Core Application Functionality to Core Assembly (Prism.Core)
- 9107 – NuGet packaging
This is great news to hear! Thanks for doing this and looking forward to the bits!
Is PRISM 4.2 coming to .NET 4.0 ?
Martin, we only plan to release Prism 4.2 for .NET 4.5.1.
It also would be nice to have the option of viewmodel first approche.
Or why dou you choose the view first approche?
Sorry. Did I misunderstand something?
The projects in the latest drop on CodePlex seem to target Framework 4.5 not 4.5.1 as stated.
Brian, we did change the prism library to target .NET 4.5 instead of 4.51 so anyone that is still on .NET 4.5 can use the library. The Stock Trader RI and the QuickStarts projects are 4.51 which includes a reference to the Prism library for .NET 4.5.
Is there an issue with targeting .NET 4.5 instead of 4.51? We are not using new capabilities of .NET 4.51 so we wanted to ensure it works for more developers.

Any chance on seeing Prism 4.2 target Silverlight 5? C'mon guys, don't forget about us!
When is the release coming of this version?
I have a huge problem with the new 4.2 release. If you use NuGet packages for Prism, Prism.UnityExtension etc. you will get a exception in the UnityBootstrapper::ConfigureContainer as it tries to register the EventAggregator. This is caused be the fact that the EventAggregator now is placed in namespace Microsoft.Practices.Prism.PubSubEvents and not as before in Microsoft.Practices.Prism.Events.
What i'm actually trying to say is… you need to update the NuGet package for Prism.UnityExtensions, so it references the correct EventAggregator.
(sidenote: it's correct if you compile the PrismLibrary – the problem is with the NuGet pacage version 4.1.0)
Karsten: Thanks for your feedback. The Prism.UnityExtensions as well as Prism.MefExtensions NuGet packages will be updated in the next release.
Karsten: A work-a-round would be to take project references to the latest UnityExtensions code but use the NuGet reference to Prism.PubSubEvents.
Francis C: Looking forward to updated NuGet packages. Is there any roughly time for release of NuGet packages?
As for workaround – i was actually thinking in the lines of something like what you suggested. I was planning to just override ConfigureContainer with code from base.
Patrick,
We are finalizing the documentation which is taking longer than we expected. We expect that this will be finished in the next 3 weeks.
Etienne,
At this point we do not plan to target Silverlight with the release. The Prism 4.1 support Silverlight 5 and will still be available.
Is there any plan to remove the platform restriction so the prim libraries can run as portable libraries on other platforms then windows?
Look like this version of Prism have been released :…/details.aspx
But I don't like the version number you have used (5.0), a version 4.5 would have been easier to understand, and what will you use if you update Prism for .Net 5 now?
Documentation have also been released here : msdn.microsoft.com/…/gg406140.aspx
Yes the code and documentation are now available. We still have a couple items to publish before everything is ready. I will publish an official blog post later today.
Bejarid,
The official announcement just went out. You can read it at aka.ms/prism-wpf-50announcement.

Here's my paraphrase of the puzzle: What is special about the numbers (and the spellings)
in this list: 4, 6, 12, 30, 33, 36, 40, 45, 50, 54, 56, 60, 70, 81, 88, 90, 100?
The order is not important, and the property we're talking about is met by no other
numbers between 1 and 100. I'll put a little space here so if you don't want to
know the answer quite yet, you don't need to see it :)
OK, so I thought, "H'm, why 'four' but not 'five'? Well 'four' and 'five' are both 4 letters long; 4 is a factor of 4 but isn't a factor of 5. 'six' is three letters, 3 is a factor of 6."
So I typed this little list into a file, which I imaginatively called tmp/cartalk-number-puzzler:
four six twelve thirty thirty-three thirty-six forty forty-five fifty fifty-four fifty-six sixty seventy eighty-one eighty-eight ninety one hundredNow, rather than counting letters by hand, I did this:
$ while read X; do echo $X ${#X}; done < tmp/cartalk-number-puzzler four 4 six 3 twelve 6 thirty 6 thirty-three 12 thirty-six 10 …Let me explain that.
- while read X; do means "read a line and assign it to $X, then execute the following."
- echo $X ${#X} means to echo (on the terminal display) the values of $X and the length of $X (which is the translation of ${#X})
- done is the other end of the do we saw above
- < tmp/cartalk-number-puzzler means "and read from this file, not from what I'm typing"
$ while read X; do Y=${X// /}; Y=${Y//-/}; echo $X ${#Y}; done < tmp/cartalk-number-puzzler four 4 six 3 twelve 6 thirty 6 thirty-three 11 thirty-six 9 forty 5 forty-five 9 fifty 5 fifty-four 9 fifty-six 8 sixty 5 seventy 7 eighty-one 9 eighty-eight 11 ninety 6 one hundred 10The two new things here are... Y=${X// /}, which means "replace all the 'blank' characters from $X by '' (nothing) and put the result into $Y — and Y=${Y//-/}; which takes $Y (i.e., the de-blanked version of $X) and replaces all the hyphens by '', storing the result back into $Y
We then print the length of $Y -- the de-blanked, de-hyphen'd version of $X -- and by inspection I think these all match the hypothesis: 10 goes evenly into 100, 6 goes evenly into 90, 11 goes evenly into 88, etc.
But wait, that's not enough! The puzzler specified that these are the only numbers between 1 and 100 with that property. I'm way too lazy to type 'twenty-one' and 'seventeen' and 'eleven' in, and I thought somebody must have written a routine to do this, so I googled "python numbers to text" (no quotes) and downloaded "Convert Numbers to Words (Python)", which works like a champ. I coded this little thing which uses num2word, like this:
import num2word for i in range(1,101): tweaked = num2word.to_card(i).replace(' ', '').replace('-', '') if i % len(tweaked) == 0: print i, tweaked, 'len =', len(tweaked)What this says is, take all positive integers up to and including 100, and calculate "tweaked" -- which is the de-blanked, de-hyphen'd version of the textual representation (i.e., num2word.to_card(i)( of the number. Then, display a message on the terminal if the length of tweaked is a factor of i. The result was:
4 four len = 4 6 six len = 3 12 twelve len = 6 30 thirty len = 6 33 thirtythree len = 11 36 thirtysix len = 9 40 forty len = 5 45 fortyfive len = 9 50 fifty len = 5 54 fiftyfour len = 9 56 fiftysix len = 8 60 sixty len = 5 70 seventy len = 7 81 eightyone len = 9 88 eightyeight len = 11 90 ninety len = 6 100 onehundred len = 10which was the list we started with.

Investors eyeing a purchase of Hertz Global Holdings Inc (Symbol: HTZ) stock, but tentative about paying the going market price of $20.68/share, might benefit from considering selling puts among the alternative strategies at their disposal. One interesting put contract in particular, is the January 2020 put at the $12.50 strike, which has a bid at the time of this writing of $2.00. Collecting that bid as the premium represents a 16% return against the $12.50 commitment, or a 8.7% annualized rate of return (at Stock Options Channel we call this the YieldBoost ).
Selling a put does not give an investor access to HTZ Hertz Global Holdings Inc sees its shares fall 39.4% and the contract is exercised (resulting in a cost basis of $10.50 per share before broker commissions, subtracting the $2.00 from $12.50), the only upside to the put seller is from collecting that premium for the 8.7% annualized rate of return.
Below is a chart showing the trailing twelve month trading history for Hertz Global Holdings Inc , and highlighting in green where the $12.50 strike is located relative to that history:
The chart above, and the stock's historical volatility, can be a helpful guide in combination with fundamental analysis to judge whether selling the January 2020 put at the $12.50 strike for the 8.7% annualized rate of return represents good reward for the risks. We calculate the trailing twelve month volatility for Hertz Global Holdings Inc (considering the last 252 trading day closing values as well as today's price of $20.68) to be 79%.

TORONTO (ICIS)--?xml:namespace>
Toronto-based RBC Royal Bank said that its monthly purchasing manager’s index (PMI) for
"Canadian manufacturing […] strengthened output and employment growth," said RBC chief economist Craig Wright in commenting on the latest PMI data.
"Greater demand from the US, Japan and China played a key role in boosting new export work which helped nudge output growth to the fastest pace of growth in the past six months,” Wright said.
“While it would be premature to suggest that the global economy is treading on a much brighter path, these modest improvements hint that better days may lie ahead," he added.
RBC conducts the monthly PMI survey in cooperation with market research firm Markit.

The default monitor for Redux DevTools with a tree view.
It shows a log of states and actions, and lets you change their history.
npm install --save-dev redux-devtools-log-monitor
You can use
LogMonitor as the only monitor in your app:
containers/DevTools.js
import React from 'react'; import { createDevTools } from 'redux-devtools'; import LogMonitor from 'redux-devtools-log-monitor'; export default createDevTools( <LogMonitor /> );
Then you can render
<DevTools> to any place inside app or even into a separate popup window.
Alternative, you can use it together with
DockMonitor to make it dockable.
Consult the
DockMonitor README for details of this approach.
Read how to start using Redux DevTools.
Every action is displayed in the log. You can expand the tree view to inspect the
action object and the
state after it.
If a reducer throws while handling an action, you will see “Interrupted by an error up the chain” instead of the state and action tree view. Scroll up until you find the action which caused the error. You will see the error message in the action log entry. If you use a hot reloading tool, you can edit the reducer, and the error will automatically update or go away.
Clicking an action will disable it. It will appear crossed out, and the state will be recalculated as if the action never happened. Clicking it once again will enable it back. Use this together with a hot reloading solution to work sequentially on different states of your app without reproducing them by hand. You can toggle any action except for the initial one.
There are four buttons at the very top. “Reset” takes your app to the state you created the store with. The other three buttons work together. You might find it useful to think of them like you think of Git commits. “Commit” removes all actions in your log, and makes the current state your initial state. This is useful when you start working on a feature and want to remove the previous noise. After you’ve dispatched a few actions, you can press “Revert” to go back to the last committed state. Finally, if you dispatched some actions by mistake and you don’t want them around, you can toggle them by clicking on them, and press “Sweep” to completely remove all currently disabled actions from the log.

What would Leo’s data model look like if I were to build it now? Leo has a long history and its current data model is the result of the evolution process. Many different ideas were combined and applied, and some of them were later abandoned. All these ideas left their trails on the model and even though we can say that it is a solid piece of code with a good performance, it isn’t very developer friendly. Using it makes your code more complex than is necessary. At least that is what I believe to be true. That is why I decided to try to make my own version of data model suitable for representing Leo’s trees.
What I like about Leo’s current tree model is how easy it is to make changes in tree. However, it makes catching the information about changes almost impossible, or at least it requires lots of processing. That makes updating view very hard. That is why I intend to make my model more centralized. Data model will provide all necessary operations for tree modification, and those operations should be the only way to modify tree.
The other thing I would try to achieve is some stability of positions in tree. If a tree is modified some positions may become invalid, but those positions that point to the nodes that are still part of the tree should be valid even after the tree has been changed. For example if we have a position that points to one specific node in the tree, and if this node, or any of its ancestors is deleted, then model should tell us that this position doesn’t exist any more. But if the node or any of its ancestors, is moved to some other place in tree, this position should still point to the same node and remain valid.
Theory of operation
Suppose that model keeps a list of all nodes in outline order. Positions would be represented by indexes in this list. But, if order of nodes is changed, those indexes would point to the wrong node. But if we add one more layer of indirection we can have immutable and persistent positions. Data model need to keep list of position names. Now, the outside code would know only about position names. Those names will be internaly in data model translated in integer indexes that would point to the specific node. If position name is removed from this translation list, then it becomes invalid which would mean position does not exist any more. If node is moved, position name should be moved accordingly and it will remain valid even after node has been moved.
... little bit later
Update
I wished to write about this mini-project simultaneously as I develop it. But once, I have started to code, I just couldn’t stop until almost all intended features were completed. Now, I can only describe what I’ve got in the end.
The code in its current version can be found here: leo-tree-model.leo.
First some helpers
To have some tree to work on it was natural to use existing Leo tree that I could see and examine easily. So, my coding started with a few helper functions for converting Leo trees to new model.
Here is the start of
LeoTreeModel class definition:
class LeoTreeModel(object): def __init__(self): self.positions = [] self.nodes = [] self.attrs = {} self.levels = [] self.gnx2pos = defaultdict(list) self.parPos = []
positionsis a list of position names. Each element in this list corresponds to one unique position in outline. As an implementation detail values are simple floats.
nodesis a list of node identificators. Implementation detail elements are just p.gnx values.
attrsis a dict containing values attached to each unique node, (its headline, body, list of parent and children identificators and size of subtree).
levelsis a list containing level for each node in outline. This is a value attached to a position rather than a node. For example one node may be several places in outline each on different level.
gnx2pos- is a dictionary of lists. Keys are gnx node identificators and values are lists of position identificators, places that one particular node can be found in outline. Nodes that are not clones have a list with the single position, while clones have more than one element in this lists.
parPosis a list of parent position identificators. For each node in outline, corresponding element in this list is a position identifier of node’s parent.
def vnode2treemodel(vnode): '''Utility convertor: converts VNode instance into LeoTreeModel instance''' def viter(v, lev0): s = [1] mnode = (v.gnx, v.h, v.b, lev0, s, [x.gnx for x in v.parents], [x.gnx for x in v.children]) yield mnode for ch in v.children: for x in viter(ch, lev0 + 1): s[0] += 1 yield x return nodes2treemodel(tuple(viter(vnode, 0))) def nodes2treemodel(nodes): '''Creates LeoTreeModel from the sequence of tuples (gnx, h, b, level, size, parentGnxes, childrenGnxes)''' ltm = LeoTreeModel() ltm.positions = [random.random() for x in nodes] ltm.levels = [x[3] for x in nodes] ltm.parPos = list(parPosIter(ltm.positions, ltm.levels)) ltm.nodes = [x[0] for x in nodes] gnx2pos = defaultdict(list) for pos, x in zip(ltm.positions, nodes): gnx2pos[x[0]].append(pos) ltm.gnx2pos = gnx2pos for gnx, h, b, lev, sz, ps, chn in nodes: ltm.attrs[gnx] = [h, b, ps, chn, sz[0]] # root node must not have parents rgnx = nodes[0][0] ltm.attrs[rgnx][2] = [] return ltm
Here is a utility iterator that yields elements of parPos list:
def parPosIter(ps, levs): '''Helper iterator for parent positions. Given sequence of positions and corresponding levels it generates sequence of parent positions''' rootpos = ps[0] levPars = [rootpos for i in range(256)] # max depth 255 levels it = zip(ps, levs) next(it) # skip first root node which has no parent yield rootpos for p, l in it: levPars[l] = p yield levPars[l - 1]
Accessing nodes data
Now that all necessary data is acquired and organized let’s see how we can access information.
To get a list of children identificators and parents identificators for any given node:
def parents(self, gnx): '''Returns list of gnxes of parents of node with given gnx''' a = self.attrs.get(gnx) return a[2] if a else [] def children(self, gnx): '''Returns list of gnxes of children of the node with given gnx''' a = self.attrs.get(gnx) return a[3] if a else []
The elements of these lists are not v-nodes like in Leo, but rather just identificators of nodes (gnx).
To access
h,
b of any given node, similar access functions can be written.
Traversing outline
To visit every position in outline one can simply use
nodes iterator.
If we have a position and want to visit parent and all ancestors:
def parents_iterator(self, p): i = self.positions.index(p) while i: p = ltm.parPos[i] yield p i = self.positions.index(p)
Subtree iterator:
def subtree_iterator(self, p): i = self.positions.index(p) gnx = self.nodes[i] sz = self.attrs[gnx][4] for j in range(i+1, i+sz): yield self.positions[j] # or yield self.nodes[j] # or yield j # depending on what we need
Following siblings iterator:
def following_siblings_iterator(self, p): i = self.positions.index(p) lev0 = self.levels[i] N = len(self.nodes) while self.levels[i] == lev0: gnx = self.nodes[i] sz = self.attrs[gnx][4] i += sz if sz >= N: break yield self.nodes[i] # or yield self.positions[i] # or yield i # depending on what we need
As you can see traversals involve only plain element access and integer arithmetic. This allows much faster traversals than Leo can achieve using its position class. Position class for traversals relies on list manipulation methods: building new lists, or appending elements to it. Accessing ivars of vnode directly may seem to be faster but in essence it is implemented in Python in the same way as accessing values from dict.
When order of traversal is not important, but we want to visit every node just once we can traverse
attrs keys. As an implementation detail in Python3.6 and newer dict keeps keys in order in which they were added to dict. This gives traversal of unique nodes a nice outline order.
I haven’t implemented any of these traversal methods in LeoTreeModel class, because they are easy to implement, and custom iterators may be better suited for the job we need to do. Sometimes it is more suitable to iterate gnx values, sometimes it is positions that we are interested in or just indexes in lists. Index is fastest to use but it is valid only as long as tree remains unchanged. Positions are immune to tree changes to some degree. And using gnxes allows fast access to children, parents, h, b…

How would you express <my_xml_element tal: ? AFAIR if you use the XML Namespaces spec, you can only have one ':' in an attribute name, so this would be invalid: <my_xml_element attr:xlink: > The same would probably be relevant for tal:defines, something like: > > <div define: define: /> You can do things like <div tal: because the ordering of definitions is explicit. How would you specify the order of definitions if you used separate attributes in the define: namespace? Attributes have no order in XML.

Yep.
So can we agree upon using DTDInst for doing the automagical translation
of DTDs to RelaxNG grammars for the time being, rather than keeping both
versions in sync manually? DTDInst's license is, seems OK for inclusion in
CVS. An Ant target who calls dtdinst.jar to do the translation should be
no problem.
I'd prefer the 'tweaking' to happen using XSLT on the generated RNG
grammar - so that is is easy to track DTD changes: using DTDInst and
re-applying tweaks with a stylesheet. Does anyone already has an idea
about the kind of tweaks which would be needed?
W.r.t. namespaces: if we want our docs to be declared in certain
namespace, we can also patch the DTD itself in order to support this:
--------------------
@@ -481,6 +480,7 @@
<!ELEMENT document (header?, body, footer?)>
<!ATTLIST document %common.att;>
+<!ATTLIST document xmlns CDATA #FIXED
"">
<!-- ==================================================== -->
<!-- Header -->
--------------------
Personally, I'm +0 whether to use namespaces for the docs or not. While
it adds to the transportability of the documents, it also adds a burden
to the stylesheet authors who should make sure to match source elements
in the correct namespace, i.e. 'document:p' instead of just 'p'.
Anyway, let's just finalize the schema/grammar issue so that we can
continue to work on something less debatable ;-)

TensorFlow CPU
The TensorFlow CPU package can be imported as follows:
import * as tf from '@tensorflow/tfjs-node'
When importing TensorFlow.js from this package, the module that you get will be accelerated by the TensorFlow C binary and run on the CPU. TensorFlow on the CPU uses hardware acceleration to accelerate the linear algebra computation under the hood.
This package will work on Linux, Windows, and Mac platforms where TensorFlow is supported.
TensorFlow GPU
The TensorFlow GPU package can be imported as follows:
import * as tf from '@tensorflow/tfjs-node-gpu'
Like the CPU package, the module that you get will be accelerated by the TensorFlow C binary, however it will run tensor operations on the GPU with CUDA and thus only linux. This binding can be at least an order of magnitude faster than the other binding options.
Vanilla CPU
The version of TensorFlow.js running with vanilla CPU operations can be imported as follows:
import * as tf from '@tensorflow/tfjs'
This package is the same package as what you would use in the browser. In this package, the operations are run in vanilla JavaScript on the CPU. This package is much smaller than the others because it doesn't need the TensorFlow binary, however it is much slower.
Because this package doesn't rely on TensorFlow, it can be used in more devices that support Node.js than just Linux, Windows, and Mac.
Production considerations.
APIs
Once you import the package as tf in any of the options above, all of the normal TensorFlow.js symbols will appear on the imported module.
tf.browser
In the normal TensorFlow.js package, the symbols in the
tf.browser.* namespace will not be usable in Node.js as they use browser-specific APIs.
Currently, these are:
- tf.browser.fromPixels
- tf.browser.toPixels
tf.node
The two Node.js packages also provide a namespace,
tf.node, which contain node-specific APIs.
TensorBoard is a notable example of Node.js-specific APIs.
An example of exporting summaries to TensorBoard in Node.js:
const model = tf.sequential(); model.add(tf.layers.dense({units: 1})); model.compile({ loss: 'meanSquaredError', optimizer: 'sgd', metrics: ['MAE'] }); // Generate some random fake data for demo purpose. const xs = tf.randomUniform([10000, 200]); const ys = tf.randomUniform([10000, 1]); const valXs = tf.randomUniform([1000, 200]); const valYs = tf.randomUniform([1000, 1]); // Start model training process. await model.fit(xs, ys, { epochs: 100, validationData: [valXs, valYs], // Add the tensorBoard callback here. callbacks: tf.node.tensorBoard('/tmp/fit_logs_1') }); | https://www.tensorflow.org/js/guide/nodejs?source=post_page--------------------------- | CC-MAIN-2019-35 | refinedweb | 416 | 51.75 |
attach to an interrupt source, you'd use either InterruptAttach() or InterruptAttachEvent().
#include <sys/neutrino.h> int InterruptAttachEvent (int intr, const struct sigevent *event, unsigned flags); int InterruptAttach (int intr, const struct sigevent * (*handler) (void *area, int id), const void *area, int size, unsigned flags);
The intr argument specifies which interrupt you wish to attach the specified handler to. The values passed are defined by the startup code that initialized the PIC (amongst other things) just before Neutrino was started. (There's more information on the startup code in your Neutrino documentation; look in the Utilities Reference, under startup-*; e.g., startup-p5064.)
At this point, the two functions InterruptAttach() and InterruptAttachEvent() differ. Let's look at InterruptAttachEvent() as it's simpler, first. Then we'll come back to InterruptAttach().
The InterruptAttachEvent() function takes two additional arguments: the argument event, which is a pointer to the struct sigevent that should be delivered, and a flags parameter. InterruptAttachEvent() tells the kernel that the event should be returned whenever the interrupt is detected, and that the interrupt level should be masked off. Note that it's the kernel that interprets the event and figures out which thread should be made READY.
With InterruptAttach(), we're specifying a different set of parameters. The handler parameter is the address of a function to call. As you can see from the prototype, handler() returns a struct sigevent, which indicates what kind of an event to return, and takes two parameters. The first passed parameter is the area, which is simply the area parameter that's passed to InterruptAttach() to begin with. The second parameter, id, is the identification of the interrupt, which is also the return value from InterruptAttach(). This is used to identify the interrupt and to mask, unmask, lock, or unlock the interrupt. The fourth parameter to InterruptAttach() is the size, which indicates how big (in bytes) the data area that you passed in area is. Finally, the flags parameter is the same as that passed for the InterruptAttachEvent(); we'll discuss that shortly.():

The Flash of Doom is one of the most annoying issues with D3 charts. You load the page, then you load the data, then you render your chart.
Everyone's staring at a blank screen while the data loads.
With React 16, we can fix that using server-side rendering and the new
ReactDOM.hydrate feature. The idea is to serve a fully rendered chart in the initial HTML payload, then take over with JavaScript and become a normal web app.
Pay close attention to that gif. The flashing red shows repaints.
When I reload the page, the whole thing re-renders and shows a line chart. Axes show up after a little while, and they're the only part of the page that re-renders.
Here's a slower version without the flashing.
Here's what you're seeing:
- You hit reload.
- Server reads
index.htmlfrom create-react-app.
- Server reads local CSV file with data.
- Server renders
<App />into the root HTML element.
- Server sends the full
index.htmlto your browser.
- Browser shows HTML with the chart.
- Browser loads remote CSV file with data.
- Browser runs
ReactDOM.hydrate()to render
<App />
<App />takes over the DOM and becomes a normal web app.
Some parts of this are efficient.
ReactDOM.hydrate avoids re-rendering parts of the DOM that were already rendered by your server. In our case, that's everything except the axes.
Some parts of this are inefficient.
The server shouldn't need to read the CSV and HTML files on every request. You could do that on startup and save the strings in a variable. They're static.
We're also rendering
<App /> and running all of our React code twice. But this doesn't need to happen every time on the server. Cache that stuff!
How-to
You can try it out for yourself on Github.
The hardest part was adding a small Express server to
create-react-app that supports
import and React syntax. I couldn't figure it out on my own, so I used Ben Lu's amazing SSR with create-react-app guide.
The main trick seems to be installing
ignore-styles so your server doesn't error out when
require-ing CSS files (no webpack), and figuring out just the right incantation of Express setup to get the server working. I tried simplifying his setup, but it didn't work.
In the end, your best bet might be to just copy his
server/ directory and go from there. Adapt
server/universal.js to render your
<App /> instead of his ReactRouter stuff.
You also have to go into
public/index.html and add
{{SSR}} to the body of
<div id="root">. The server looks for
{{SSR}} and replaces it with the rendered HTML from your React app.
You can see my server-side code that reads a CSV file and renders the chart into a string on GitHub.
Adapting Your React D3 App to Server-Side
Adjusting to server-side rendering required a small mind shift in the way I built my chart. Usually, I like to use
componentWillMount in the
<App /> component to load data. Until data loads, the app renders a
null; after that, it returns a chart component.
This makes apps easy to build and avoids issues with undefined data when rendering.
But it throws away all the benefits of server-side rendering. With the
componentWillMount approach, you're loading the fully rendered chart, replacing it with an empty component, then re-rendering it once data loads on the client.
Here's what you do instead: accept data as props. Only load in
componentWillMount if no data was given.
Like this:
class App extends Component { constructor(props) { super (props) ; this.state = { data: (props.data || [ ] ).map ( this.rowParse ) } } dateParse = d3.timeParse ( "%d %b %Y" ) ; rowParse = ( { date, time, runner } ) => ( { date: this.dateParse (date) , time: time.split ( ':' ) .map ( Number ) .reverse ( ) .reduce ( (t, n, i) => i > 0 ? t+n* 60 **i : n) , runner } ) ; componentWillMount( ) { if ( ! this.state.data.length ) { d3.csv ( "" ) .row ( this.rowParse ) .get (data => this.setState ( { data } ) ) } } // render stuff }
In the
constructor, we copy data from props into
state. That's because components that load their own data usually keep it in state and putting it there means fewer changes to the rest of your code.
rowParse is a helper method that turns individual rows from CVS strings into correct data types: dates for
date, seconds for
time to win the marathon, and
runner stays a string.
In
componentWillMount, we now check if the data is already present. If it isn't, we load it and everything works the same as it always has.
Hydrate After Data Loads
The final piece of the puzzle is hydrating your app after your data is done loading. You're already showing a chart, so there's no need to be hasty and
ReactDOM.hydrate as soon as your JavaScript loads.
You can't detect that your component already had children and avoid replacing them until you're ready. Instead, you can wait to hydrate in the first place.
d3.csv ( "" ) .row ( this.rowParse ) .get (data => ReactDOM.hydrate ( <App data= {data} />, document.getElementById ( 'root' ) ) ) ;
And you have successfully solved the Flash of Doom seen in most D3 charts.
Caveat
Now you need a server. No more static page serverless web app for your beautiful chart. No gh-pages and simple hosting...
You could use now.sh, and that's nice, but I don't know how to make it run my server. See:
The panacea is to figure out how to tweak the create-react-app build process to insert your server-side rendered
<App> right into its
index.html. That's what I really want.
I wonder if they'd accept a PR for that...

It's specifically and intentionally not an object class. You cannot subclass it. You cannot provide methods. You cannot apply roles or mixins or metaclasses or traits or antlers or whatever else is in fashion this week.
On the other hand, it is tiny, single-file, creates cheap lightweight array-backed structures, uses nothing outside of core. And I defy anyone to even measure its startup overhead with a repeatable benchmark.
It's intended simply to be a slightly nicer way to store internal data structures, where otherwise you might be tempted to abuse a hash, complete with the risk of typoing key names.
Would anyone use this, if it were available?
+1 for the idea, though the implementation could use a little bit of polish I think.
Random thoughts:
- Why is $fields an array ref instead of an array?
- Should there be some friendly message if someone does "use struct;" or "use struct Foo;"?
- Should field initialization be required?
- structs could do with a nice stringification. maybe.
- "use struct" is *extremely* close to "use strict"
- Since these are explicitly not objects, it would be nice for the "method missing" message to say something less OOPy and to not mention "struct::impl::" at all.
@PerlPilot: Hmmmmyes, I should respond to these:
> - Why is $fields an array ref instead of an array?
A reasonable question. I was thinking about ability to give other options, but I guess those are rare, and can just go in a HASHref at the beginning or end. So maybe an array is nicer.
> - Should there be some friendly message if someone does "use struct;" or "use struct Foo;"?
Sounds good.
> - Should field initialization be required?
Most likely just assert in the "constructor" that
@_ == @fields or croak "Usage: $name(".join(",",@fields).")";
> - structs could do with a nice stringification.
maybe.
Hard to see at a glance what that stringification ought to be, really. It's possible there's something but nothing obvious comes to mind.
> - "use struct" is *extremely* close to "use strict"
Fair point. How about Struct::Dumb? I quite like that - it suggests "these are stupid", simple stores of data. Also has slight pun-worthy potential. :)
> - Since these are explicitly not objects, it would be nice for the "method missing" message to say something less OOPy and to not mention "struct::impl::" at all.
Another good point.
I like the non-OO part. Consider putting it on CPAN.
For C-compat it would be a string and you select the fields with pack/unpack. This way you can even share them with C if you get the sizes and aligns right.
you'd need to work on the namespaces. consider...
package One;
use struct Point => [qw( x y )];
package Two;
use struct Point => [qw( a b )];
I will.

In this article, we will write a Java program to find Quotient and Remainder, when one number is divided by another number.
Example: Program to find Quotient and Remainder
In the following program we have two integer numbers
num1 and
num2 and we are finding the quotient and remainder when num1 is divided by num2, so we can say that num1 is the dividend here and num2 is the divisor.
public class JavaExample { public static void main(String[] args) { int num1 = 15, num2 = 2; int quotient = num1 / num2; int remainder = num1 % num2; System.out.println("Quotient is: " + quotient); System.out.println("Remainder is: " + remainder); } }
Output:
To compute the quotient and remainder we have created two variables with the name quotient and remainder respectively.
To find the quotient we divide the num1 by num2 using
/ operator. Since both the variables num1 & num2 are integers, the result will be integer despite the fact that the result of 15/2 is 7.5 mathematically. So the value assigned to the variable
quotient after the operation is 7.
To find the remainder, we use the % operator. The remainder of 15/2 i.e 1 is assigned to the variable
remainder after operation.
At the end of the program the values of variables
quotient and
remainder are printed.

Can anyone please tell me what is the difference between below two functions? They both look pretty similar except for

None
This is called type hinting, and is only used to help make it easier for the programmer to understand the return and input types of a program, as well as allow for external linting and static analysis programs to work on Python. Here is the official RFC explaining why it exists.
Type hints are not actually used by Python anyway (because Python is dynamically typed - the types are determined at runtime, not at compile time when the source is actually parsed) and can be safely omitted.
Functions conforming to you Version 2 are perfectly fine in every case.
Python 3 has inbuilt support for type hints with the
typing module, while Python 2.7 requires the third-party
mypy module. | https://codedump.io/share/p5dvcOtDkQkP/1/use-of--gt-in-python | CC-MAIN-2017-30 | refinedweb | 149 | 58.62 |
This is related to my question, here.
I now have the updated code as follows:
import numpy as np import _pickle as cPickle from PIL import Image import sys,os pixels = [] labels = [] traindata = [] i = 0 directory = 'C:\\Users\\abc\\Desktop\\Testing\\images' for root, dirs, files in os.walk(directory): for file in files: floc = file im = Image.open(str(directory) + '\\' + floc) pix = np.array(im.getdata()) pixels.append(pix) labels.append(1) pixels = np.array(pixels) labels = np.array(labels) traindata.append(pixels) traindata.append(labels) traindata = np.array([traindata[i][i],traindata[1]], dtype=object) i = i + 1 # do the same for validation and test data # put all data and labels into 'data' array cPickle.dump(traindata,open('data.pickle','wb')) FILE = open("data.pickle", 'rb') content = cPickle.load(FILE) print (content)
When having only one image, the code runs fine. But, when I add another image or more, I get the following:
Traceback (most recent call last): File "pickle_data.py", line 17, in <module> pixels.append((pix)) AttributeError: 'numpy.ndarray' object has no attribute 'append'
How can I solve this issue?
Thanks.
Kenil Vasani
So far ok. But you want to leave
pixelsas a list until you are done with the iteration.
You had this indention right in your other question. What happened? previous
Iterating, collecting values in a list, and then at the end joining things into a bigger array is the right way. To make things clear I often prefer to use notation like:
If names indicate something about the nature of the object I’m less likely to get errors like yours.
I don’t understand what you are trying to do with
traindata. I doubt if you need to build it during the loop.
pixelsand
labelshave the basic information.
That
comes from the previous question. I’m not sure you understand that answer.
if done outside the loop is just
labelsis a 1d array, a bunch of 1s (or [0,1,2,3…] if my guess is right).
pixelsis a higher dimension array. What is its shape?
Stop right there. There’s no point in turning that list into an array. You can save the list with
pickle.
You are copying code from an earlier question, and getting the formatting wrong. cPickle very large amount of data | https://www.errorcorner.com/question/python-attributeerror-numpy-ndarray-object-has-no-attribute-append/ | CC-MAIN-2021-04 | refinedweb | 384 | 61.33 |

Building a Personal Web App Head To Toe With Symfony 2
- Building a Web App with Symfony 2: Bootstrapping

The code we'll be using is identical to the code from Part 2 – the features are already there, they just weren't discussed.
Image watermarks
Seeing as there's already plenty of image manipulation and watermarking through Imagick tutorials available on SitePoint, and owing to the fact that we don't do any advanced image manipulation in this particular project, we'll stick to PHP's default image mainpulation library – GD.
In general, when there is "image processing", we are talking about an action or actions applied to an image before we eventually show it using the
<img> tag. In my application, this is done in two steps:
- Create a route to capture the "image display request" and map it to an action in a controller.
- Implement the processing in the action.
Route configuration
The route for displaying an image after processing is simple:
cover: pattern: /books/cover/{id}_{title}_{author}_{width}.png defaults: {_controller: trrsywxBundle:Default:cover, width: 300}
In a template, we can invoke the call to display the processed image by:
<img src="{{path("cover", {'id':book.id, 'author':author, 'title':book.title}) }}" alt="{{book.title}}'s cover" title="{{book.title}}'s cover"/>
So every time this
<img> tag is encountered, a processed image will be displayed.
Image processing
In this application, we do two things before displaying the image:
- Depending on whether or not a book cover image exists, display it, or display the default cover image;
- Add a watermark and adjust the size (300px wide in book detail view and 200px wide in reading list view).
The complete code is in
src/tr/rsywxBundle/Controller/DefaultController.php in the function
coverAction. The code is simple and straightforward and I'll just show you the output in Detail View for both a real book cover and a default cover:
Note that I have created a "cover" folder under "web" to hold the default cover and the scanned book covers. I also used a Chinese TTF to display the watermark texts. Please feel free to use your own font (and copy that font to the "cover" folder).
On a higher-traffic site, the correct course of action would be to cache the autogenerated images much like Lukas White did in his article, but I'll leave that up to you to play around with.
Pagination
There are also a lot of articles on paginating a big dataset. In this tutorial, I will show you how I did it in this app, and we'll test it.
The source code for the class is in
src/tr/rsywxBundle/Utility/Paginator.php.
The code itself is easy to read and does not involve anything particularly advanced, so I will just discuss the process.
There are two fundamental values in a Pagination class:
- How many records in total and how many pages in total?
- What is the current page and how to construct an easily accessible page list for further processing ?
Many pagination classes often deal with data retrieval too, but this is not good practice: pagination should only deal with things related to pagination, not the data itself. The data is the domain of the Entity/Repository.
If we go back to the implementation of getting the books matching certain criteria, you will notice how the two steps (get data and do pagination) are separated in the controller:
File location: src/tr/rsywxBundle/Controller/BookController.php
public function listAction($page, $key) { $em = $this->getDoctrine()->getManager(); $rpp = $this->container->getParameter('books_per_page'); $repo = $em->getRepository('trrsywxBundle:BookBook'); list($res, $totalcount) = $repo->getResultAndCount($page, $rpp, $key); //Above to retrieve data and counts //Below to instantiate the paginator $paginator = new \tr\rsywxBundle\Utility\Paginator($page, $totalcount, $rpp); $pagelist = $paginator->getPagesList(); return $this->render('trrsywxBundle:Books:List.html.twig', array('res' => $res, 'paginator' => $pagelist, 'cur' => $page, 'total' => $paginator->getTotalPages(), 'key'=>$key)); }
The constructor of my paginator takes 3 parameters:
- page: to tell what is the current page. This will be used to return a list for pages to show as clickable links in the template;
- totalcount: to tell the count of the results. This will be used to calculate the total pages together with the rpp parameter;
- rpp: short for records per page.
In my current implementation, I used a simple version of pagination showing only "First", "Previous", "Next", and "Last" page links, but you can try out different types by using the
getPagesList function.
Take for example a page list like this:
1 2 3 4 5
The key here is in the
getPagesList function which makes sure that the current page is always in the middle, or if there aren't enough pages, it makes sure it's in the correct position.
public function getPagesList() { $pageCount = 5; if ($this->totalPages <= $pageCount) //Less than total 5 pages return array(1, 2, 3, 4, 5); if($this->page <=3) return array(1,2,3,4,5); $i = $pageCount; $r=array(); $half = floor($pageCount / 2); if ($this->page + $half > $this->totalPages) // Close to end { while ($i >= 1) { $r[] = $this->totalPages - $i + 1; $i--; } return $r; } else { while ($i >= 1) { $r[] = $this->page - $i + $half + 1; $i--; } return $r; } }
To make sure this function really works, we'll have to test it before using it. We'll use PHPUnit as the test bench. Please refer to the official site for detailed instructions on how to install it. I used the phpunit.phar way to download the package and place it in my project root folder.
To test the Paginator class we just created, firstly we need to create a folder
Utility under
src/tr/rsywxBundle/Tests. All tests in Symfony should go under
src/tr/rsywxBundle/Tests. In the
Utility folder, create a PHP file named
PaginatorTest.php:
namespace tr\rsywxBundle\Tests\Utility; use tr\rsywxBundle\Utility\Paginator; class PaginatorTest extends \PHPUnit_Framework_TestCase { public function testgetPageList() { )); } }
This kind of test is called a Unit Test. It tests a particular unit of the program.
In
testgetPageList function, we basically instantiate the object we want to test (a paginator) with virtually any combination of parameters we can think of. We then call some methods of that object and test the validity of the result by using assertions. Here we only use the method
assertEquals.
In the example
$this->assertEquals($list, array(7,8,9,10,11)) from the
$paginator object we created, we know there should be a total of 11 pages (with 101 records in total and 10 records per page), and page 10 as the current page will return a page list
7,8,9,10,11 as page 10 is very close to the end. We assert this and if that assertion fails, there must be something wrong in the function logic.
In our command line/terminal, we run the following command:
php phpunit.phar -c app/
This reads the configuration file for PHPUnit from the
app/ folder (
phpunit.xml.dist is generated by the Symfony installation. DON'T CHANGE IT!)
Note: Please delete all other test files auto-generated by Symfony (like
Controller folder under
Tests). Otherwise, you will see at least one error.
The above command will parse all test files under
Tests and make sure all assertions pass. In the above example, you will see a prompt saying something like
OK, 1 test, 4 assertions. This means all the tests we created have passed and thus proved the function behaves properly. If not, there must be something wrong in the code (in the implementation or in the test).
Feel free to expand the test file for the Paginator class.
It is always a good practice to test a home-made module before it is used in your program.
For a more in-depth look at PHPUnit and testing in PHP, see any of SitePoint's numerous PHPUnit articles.
NativeQuery
Our database has a table called
book_visit, we use timestamp as the data type to log the time of a visit to the book detail page. We need to do some statistics aggregation on the visits and one of them is to get the total visit count by day (my "day" is in the +8 hours timezone).
In SQL, this is easy:
select count(v.bid) vc, date(from_unixtime(v.visitwhen+15*60*60)) vd from book_visit v group by vd order by vd
In the above,
15*60*60 is there to adjust my server time to my timezone.
However, if you try to use similar grammar in Symonfy (changing the table name to its FQN, of course), an error prompt will tell you something like
date function is not supported. To solve this, one way is to use pure SQL:
$q = $em->getConnection()->prepare('select count(v.bid) vc, date(from_unixtime(v.visitwhen+8*60*60)) vd from book_visit v group by vd order by vd'); $q->execute(); return $q->fetchAll();
Or as recommended by Symfony and Doctrine, we can (and should) use
createNativeQuery and
ResultSetMapping.
public function getVisitCountByDay() { $em = $this->getEntityManager(); $rsm=new \Doctrine\ORM\Query\ResultSetMapping; $rsm->addScalarResult('vc', 'vc'); $rsm->addScalarResult('vd', 'vd'); $q=$em->createNativeQuery('select count(v.bid) vc, date(from_unixtime(v.visitwhen+15*60*60)) vd from book_visit v group by vd order by vd', $rsm); $res=$q->getResult(); return $res; }
In the example above, the most critical statements are to create a ResultSetMapping and add results to that mapping.
vc (visit count) and
vd (visit date) both appeared twice in the
addScalarResult call. The first is a column name that will be returned from the query and the second is an alias for that column. To prevent the complication of creating more names, we just use the same names.
A scalar result describes the mapping of a single column in an SQL result set to a scalar value in the Doctrine result. Scalar results are typically used for aggregate values but any column in the SQL result set can be mapped as a scalar value.
The above functionality is not implemented in the final code. Take it as home work.
Conclusion
This is far from a complete tutorial for Symfony. There's plenty not covered (forms, security, functional testing, i18n, etc), which could easily take another 10-12 parts. I highly recommend you read the full official documentation provided by Symfony, which can be downloaded here.

I think it should be quite easy to create a rock so I may do it in the next few days. > P.S.: Elementary Plot sounds a little confusing to me as there is > another Elementary that plot library might be using for graphical > output: >. It was very hard for me to find a good name for the library and elementary was the best name I come out with. I was afraid to delay publishing the library just because I didn't have a name. I didn't know about the elementary library you was talking about but I thought that elementary is so generic it may already be used. If people have suggestions I am open to change the name of the library. It needs to be easily translated into a short namespace name for C++ like something between three and six letters max. For the moment it is "elem::" in C++. As long as I don't have any better idea the elementary name is good enough for me.

The following will make your builds (running on a TFS Server) execute your unit tests after the build:
Thats it - check in this file and queue a build.
An error I got while getting this working indicated that the MSTest.exe could not be found - this was because TFS Client had not been installed on the build server - once these were installed it worked fine.
Something else you may want to do is ensure that a build is triggered every time someone checks in. To do this, edit your build definition (right click on your build within Team Explorer and choose "Edit Build Definition...") - click on the 'Trigger' item in the list on the left and make sure the "Build each check-in (more builds)" item is checked.

The following exception occurs in ASP.NET (version: 2.0.50727.1433) when you trigger an event on an ASP.Net object that has no ID set, eg clicking on a LinkButton: fix for this is to simply make sure the object has an ID assigned to it eg:

The following error occured when 2 requests hit an ASP.NET (2.0) web app (using SQL Server 2005) at the same time:
The connection was not closed. The connection's current state is open
Normally this only occurs if you have a connection that is not being closed. However in our case all connections where being closed using a try-finally block (personally I prefer using a using block).
This error only occured when the 2 request were initiated from different machines.
It turns out that the error occured because the same username was being used for all requests (we were not interested in the username in the app - and simply validated the request through a token and set the username to the same static string for all requests). As soon as we made the username unique (by appending a guid to it) the error ceased to occur.
This indicates that ADO.NET uses the username as part of it's connection pooling management.
*** UPDATE 17 Nov 08 ***
After more testing we proved this theory incorrect. We found that the root cause of the original exception (connection state is open) was because we used a static member in one of our ORM classes - this held on to the connection, and it never got closed (hence the exception) - once we converted this to a non-static variable the problem disappeared. However, adding the GUID to the ASP.NET username did have the above mentioned affect in several scenarios - which still leads me to believe the username has some relation/use in the connection pooling management (not sure why - as it's the process's identity that things run as - not the user's).
For some time I've been wondering if there's a better way to program business logic. Years ago I used to write COBOL, then moved onto a 4GL, bla bla bla... and today I find myself well entrenched in OO with Microsoft's .Net. Development times don't seem to be much better these days - and the complexity of things seems to have mushroomed.
We went from barely-a-3GL to 4GL back to 3GL plus an explosion of things you need to consider. We started with procedural code then moved to OO and seem to have got stuck there. But somehow I think we need to revise our use of OO. Business logic is predominantly procedural code - even if written in OO; it starts, follows a process, performing stuff until finished eg Customer.UpdateCreditLimit()
OO is really good for modelling things - as per the classic OO examples of a bicycle or car. And thus they model business things quite well too - like an Invoice or a Customer.
However, I've found that the more object oriented the code gets - the less productive, maintainable and flexible it becomes. Not saying leave OO - far from it - it's brilliant. It's just that we need to learn when to say 'when'. The use of patterns has helped a huge amount - but these can also caused similar problems - when being applied where they aren't really needed - resulting in overly complex software (read: inflexible and unmaintainable and unproductive). It's a fine line - and it's not easy to get the balance.
A major break through in this area is LINQ. This has meant we have less clutter in our apps catering for ORM (brilliant). This has resulted in code very similar to the old 4GL days (essentially 4GLs were just SQL based code anyway) - where all you care/code about is the business logic - caring not a jot about how or where a Customer or Order got created - and in this age of SOA - that becomes more important (as a Customer could come from many different sources - local RDBMS, company ERP, external CRM etc). I guess you could say LINQ allows you to focus your code to be more domain specific (not saying it's a DSL).
I have been playing with workflows for donkeys of years and found that although the individual workflow systems themselves can range from very simple to incredibly complex - the individual tasks they perform need not be. This had lead me to start thinking about applying this principle to code design at a reasonably low level.... what if we developed tasks as objects. Each task has just one job (I've heard some people say this is how objects 'should' be coded anyway). It has properties that can be get/set. Keeping things dead simple, eg:
public class AdderTask
{
public int Addend1 { get; set; }
public int Addend2 { get; set; }
public int Result { get; set; }
public AdderTask(int addend1, int addend2)
{
Addend1 = addend1;
Addend2 = addend2;
}
public AdderTask Execute()
{
Result = Addend1 + Addend2;
return this;
}
}
To run this you'd simply do this:
int result = new AdderTask(1, 2).Execute().Result;
Exposing the task's properties means you can build up get and set statements - and because the Execute method returns the task object itself you can easily use it in a single line as if it was a method on it's own - or retrieve it's property values after the Execute (these tasks would easily be adapted to work within a workflow system).
This style lends itself to expanding; rather like building blocks, you can build large workflows out of these task oriented blocks. The workflows themselves coded just like these tasks - whereby all the business logic resides within the Execute() method.
Adding LINQ to the mix takes this to the next level - allowing you to build software that is simple to develop and understand.
I've been building a sizable system using this technique and I'm finding that I'm converting code developed using standard OO practices over to this methodology as it makes code more easily reused - but most importantly: easier to read and maintain.
In summary:
Other notes:
Suggestions/comments very welcome - I'd like others to expand or comment on this.

A couple of notes regarding absolute positioning in FF and IE...
Specifying position values:
Using other elements parents to calculate your object's position:
The scenario might be you have a div that you want to position over or by another object - but that object has no position values. In this case I use parent object values.

Sometimes Visual Studio 2008 (Team System Developer Edition - with Team Explorer and TFS Power Tools) crashes (disappearing completely) when running unit tests.
I have not yet tried SP1 for VS2008 - will hopefully try this in the next week or two.
Not really sure what causes this - but have noticed that the following error is written to the windows event log prior to the crash (not at the same time).
Event Type: Error
Event Source: VSPERF
Event Category: None
Event ID: 1406
Date: 22/08/2008
Time: 16:27:18
User: N/A
Computer: MYPC
Description:
There was an error connecting to the Logger Engine while registering C:\Dev\DEV\Release1\Source\MyWebProject\bin\MyWebProject.dll for coverage.
Initially I thought it was a particular test or peice of target code that caused it, but found that the crash occured at seemingly random moments ie I tried running all tests and it would crash at test number 259 (out of 264), then tried running the first 100 tests and it crashed - then tried the last 20 tests and it crashed- even tried running 1 test and it crashed. This was the worst case of this problem - over the past few weeks it (VS crashing/disappearing) would only happen every now and then.
The only work around I've found is to replace or remove the workspace and start again...

When trying to debug javascript using Visual Studio 2008 there a couple of things you need to do first - otherwise it (debugging) will not work and you'll get the following error when you hover over breakpoint in your javascript:
The breakpoint will not currently be hit. No symbols have been loaded for this document.
Note that this is only for debugging using IE (6) - not sure about other browsers/versions.
That's it - when your breakpoint is reached the VS debugger will be triggered.

For those of you wanting to know just what is being sent (posted) back from the client (browser) to the server (ASP.NET) - when a postback occurs - use the following lines in your C# ASP.NET program:
Either look at the output window or put a break-point on the last line so you can use the debugger to view the variables values at runtime.
Note that this only the information within the HTTP POST payload. There are also things like the HTTP headers, cookies etc (all of which you can query in a similar fashion - all within the Page.Request object).
Normally I'd use a tool like Fiddler for this type of interogation - but sometimes it's just as quick and easy to do it in the code like this.

For those of you who don't have access to IE or FF dev toolbars - this is how we used to do client side runtime debugging...
Drop the following code into your web page (preferrably at the bottom):
<script>
function log(text){
document.getElementById("logArea").value = text;
}
function dump(){
log(document.body.innerHTML);
}
function logProps(obj){
var msg = "";
for(var i=0;i<obj.attributes.length;i++)
{
msg+=obj.attributes[i].nodeName + ": " + obj.attributes[i].nodeValue + "\r\n";
}
log(msg);
}
</script>
<input ondblclick="eval(this.value)" /><br />
<textarea id="logArea" cols="80" rows="20"></textarea>
This should be self explanatory - the html controls provide a place to enter and run javascript (eg to query the DOM at runtime) and somewhere to dump the data. And the javascript provides some helper functions - for dumping data and for querying all the properties of an object.
The following is a IE specific version of the for loop which may show a few other properties:
for(x in obj)
{
msg+=x + ": " + obj[x] + "\r\n";
}

For some reason some controls/tags within ASP.NET do not always get rendered/passed to the client.
This has happened to me on a number of occasions. It seems limited to <style> and <script> tags - but happens for both raw HTML (within the aspx designer) and dynamically created tags (eg using new HtmlGenericControl("style")...).
This is happening to controls/tags within AJAX updatepanels within, webforms and usercontrols.
Sometimes I can work around this by simply placing these controls/tags some where else within the page structure. But the most consistent way to get around this issue is to place a non-blanking space before the tag eg:
<style>...
Another half-baked solution hit's the road ;-)
Update:
After some investigation, I have found a not-so-half-baked solution - for getting javascript loaded and run on a page during an AJAX postback...
The solution is to not try and add a script tag by adding it to a control within the page - but rather use the ASP.NET AJAX ScriptManager class's RegisterStartupScript() method. There are two overloads for this, one loads/registers the script and runs it just once (initial page load) and the other on each asynchronous postback (the latter suited my needs).
The following javascript error occurs when trying to use the Telerik controls and you haven't updated your ASP.NET (2.0) web.config file correctly.
Error: 'Telerik' is undefined
To fix make sure the following lines are within the <system.web> section of your web.config file:
<httpHandlers>
<add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false" />
<add path="ChartImage.axd" verb="*" type="Telerik.Web.UI.ChartHttpHandler, Telerik.Web.UI, Version=2008.1.515.20, Culture=neutral, PublicKeyToken=121fae78165ba3d4" validate="false" />
<add path="Telerik.Web.UI.WebResource.axd" verb="*" type="Telerik.Web.UI.WebResource, Telerik.Web.UI, Version=2008.1.515.20, Culture=neutral, PublicKeyToken=121fae78165ba3d4" validate="false" />
</httpHandlers>
In my case I was missing the ScriptResource.axd line. Also, you only need the ChartImage.axd line if you're using the chart control.

With a clean install of Scuttle I found that both the import bookmarks pages (importNetscape.php and import.php) do not work - instead the both display the source of the PHP files.
This is caused by both files not having the correct php declaration at the beginning of the file eg -both of these files first line was:
<?
However they should have been:
<?php
So just simply update these files.
I got the following error on a fresh install of Scuttle (0.7.2) on a newly created Windows Server 2003 with PHP (5.2.6), MySQL5.0.51b) and IIS 6:
After googling for a while I found this simple solution (here: posted by CharlesW):
Add the line: if (!defined('LC_MESSAGES')) define('LC_MESSAGES', 5);
to the top of functions.inc.php.
Thanks a million CharlesW!!!

It seems every time I try to install PHP and MySQL something doesn't work - usually there's either a file missing from the PHP distro or something in the install notes is missing or incorrect. This time it was both.
I first tried the PHP msi install - first mistake. As it does not include the MySQL extensions - neither does the 5.2.6 PECL zip file (I mistakenly thought this would include all the extensions). So if you've installed PHP using the MSI installer - uninstall it (via Control Panel - Add/Remove Programs). Also - you may need to manually remove any remants of this PHP installation manually - I had to manually delete the php directory.
Now with a clean slate do the following:
Bingo - that's it. To test create a file called phpinfo.php (and place in the web root) with the following:
<?php
phpinfo();
?>
The critical part to check here is that the output of this phpinfo shows the 'Loaded Configuration File' is set to the php.ini file you created above. If PHP is configured correctly to use mysql it this (phpinfo output) will have a MySQL section - if this is missing - then something is wrong.

Relaxed unused importsRelaxed unused imports
Unused imports describes how the current unused imports warning works. An import is unused if it can be deleted without changing the meaning of the program; currently, GHC strives to report all such imports (although it doesn't guarantee that it will do so).
In this proposal, we identify some unused imports for which we should NOT report a warning. The underlying motivation is that, assuming a module M compiles without unused import warnings, if one of the modules it imports adds an extra export, then M should continue to compile without warnings. (This is equivalent to stating that a minor version upgrade under the Haskell PVP should not trigger new warnings.)
This is achieved is as follows: an import is unused if it can be deleted without changing the meaning of the program, EXCEPT if the import explicitly brings
x into scope (e.g.,
import A (x)), and the only other ways
x was brought into scope are implicit (e.g.,
import B), AND each such implicit import is of a different module (e.g.,
import A (x) is still redundant if we
import A).
MotivationMotivation
Snoyman reports (with reddit discussion) a common CPP anti-pattern in cross-GHC code:
#if MIN_VERSION_base(4,8,0) import Control.Applicative ((<*)) #else import Control.Applicative ((<*), pure) #endif
The reason the CPP is necessary is because in base-4.8, an export of
pure was added to
Prelude; this means that
Control.Applicative's import of
pure is redundant.
Although the import is technically redundant, it is extremely inconvenient, because a minor, backwards-compatible change to a package caused a redundant import warning to surface. In order for this code to be warning-free on the newer version of base, we must omit
pure from
Control.Applicative; however, the older version of base will not compile without this error! Instead, we would like
import Control.Applicative ((<*), pure) to NOT report any warnings, even if
Prelude starts exporting
pure.
See also #10117 for a problem with a common workaround for this problem.
SpecificationSpecification
Say that an import-item is either an entire import-all decl (eg
import Foo),
or a particular item in an import list (e.g.,
import Foo( ..., x, ...)). An
imported name can be provided implicitly or explicitly by an import item; specifically
an imported name
x is explicitly provided if it appears textually in the original
import statement, and implicitly otherwise (i.e., if there was no import list, or
it was brought into scope via ellipses
C(..)).
Then, for each use of an imported name, we will attribute that use to all import-items which implicitly provide it, AND one import-item which explicitly provides it. Then, any import items with no uses attributed to them are unused, and are warned about. I've highlighted in bold the differences from the previous specification..
Partition the import-items for a
RdrNameby their
Module(e.g.
Aof
import A) and whether or not the explicitly and implicitly provide the
RdrName(
import Preludeimplicitly provides
Just;
import Prelude (Just)and
import Prelude (Maybe(..))explicitly provides
Just.). For each
Module, mark one implicit import-item (if it exists) as used. Among the explicit imports of a
RdrNamewhose
Modules had no implicit import-items associated with them, pick one and mark it as used.
Now bleat about any import-items that are unused. For a decl
import Foo(x,y), if both the
xand
yitems are unused, it'd be better to bleat about the entire decl rather than the individual items.
Step (2) is nondeterministic in two ways: the selection of the implicit import-item (per
Module), and the selection of the explicit import item (across all
Modules.) We need some total order over import-items to let us decide which to pick: we just prefer the textually first.
The addition is a bit involved, but essentially we want to compute some set of import-items to mark as used. Here are some important motivating examples:
For each module, mark one implicit import-item as used.
-- Prelude and Control.Applicative export pure -- We want no errors here; thus, we need to mark both Prelude -- and Control.Applicative as used. These are different modules, -- so we mark each of their implicit imports as used. import Prelude import Control.Applicative bar = pure -- We want to report a warning here; for any module (in this case -- Control.Applicative) we only mark one import-item as used. import Control.Applicative import Control.Applicative bar = pure
Among the explicit imports whose
Modules had no implicit import-items associated with them, pick one and mark it as used.
-- We want to report the second import as redundant. Thus, because -- M has an implicit "import M", we do not mark the second import as -- used. import M import M (x) -- We don't want to report any warning here. We mark Control.Applicative -- as used because there is no "import Control.Applicative" import Prelude import Control.Applicative (pure) -- We want to report one import as redundant. Thus, among the eligible -- explicit import-items (across module names), we only mark one as used. import M (x) import N (x)
import Prelude (Maybe(..)) is an explicit import of
Just.
-- Prelude and Data.Maybe export Maybe(Just, Nothing) -- We want to report a warning here; since Maybe(..) is an explicit -- import we only pick one import item to mark as used. import Prelude (Maybe(..)) import Data.Maybe (Just) bar = Just
ExamplesExamples -- using 'when' (exported by Control.Monad and .State), -- 'State' and 'Reader'
Under this proposal, we get the following behavior:
- X0:
import Foo ( x )redundant (there is an implicit import of Foo).
- X1:
import Foo ( x )redundant (there is an implicit import of Foo).
- X2:
y of import Foo ( x, y )redundant, and
import Foo ( x )redundant (in both cases, we only picked one explicit import to mark as used).
- X3:
import Foo ( x )redundant (ditto).
- X4: Second
import Foo ( x, y )redundant (ditto).
- X5:
import Foo ( x, y )redundant (only first import's y can be marked as used by
Bar.yname).
- X6:
xin
import Foo( x, y ) as Barand
yin
import Foo( x, y )redundant as they were not marked used
- X7:
import FooPlus(z,x)and
yin second import redundant
- X8: NOTHING marked redundant! (Use of

Customizing SOAP Message Formatting
For ASP.NET Web services that use SOAP to communicate with clients, a sophisticated mechanism is available for controlling the format of the SOAP messages sent in requests and responses. SOAP dictates that the contents of the SOAP messages sent to and from a Web service must be in XML contained in Body and Header elements that in turn are children of an Envelope element (belonging to the namespace). However, SOAP does not restrict the formatting of the XML.
To produce and consume Web services that use different formatting, the .NET Framework provides an attribute-based mechanism for controlling the format of the XML in the SOAP message. In addition, an attribute-based mechanism for specifying the specific element and attribute names of the SOAP sent over the network is available for controlling the SOAP at a finer level of detail.

(One of my summaries of a talk at the 2015 django under the hood conference).
Iacopo Spalletti is one of the core developers of django CMS. Django CMS was invited to give a talk because it is a big Django application. So it can tell us what’s the good, the bad and the ugly about Django from their perspective.
Django CMS is a good django citizen. It integrates with other django apps. It provides features to other applications. It glues applications together. It handles unstructured content using “pages”.
Django is upgradable. It takes some work, but it is doable and not very painful. Similarly django CMS.
The basis of django CMS is the Page and a tree hierarchy in which those pages are placed. And of course a template to render it. Django CMS is multilingual at the core, so everything is translatable. A title is a separate Title object. Similarly the actual content. And so on.
Django CMS uses a lot of django features. Of the 14k lines, 3k are in the
admin and 2k in the models, for instance. And 1k lines in the template tags:
that is a lot. It is a central part of django CMS to work with templates. Tags
such as
{% cms_toolbar %} to inject the cms toolbar. And
{% placeholder
'some-thing' %} for injecting something from the django CMS content into the
template.
The good: the admin. The admin has its quirks, but it works very well. One third of the CMS code is admin-related.
They have a plugin mechanism, often centered around providing placeholders that can later be inserted into the page. A plugin looks very much like a view and is often used in the same way: it has to render content for the web page. There’s also a mechanism that works much the same as middleware and context processors in django itself would.
It is all very database-intensive, so django CMS tries to cache things a lot.
The bad: the ORM. Actually, the bad is the way django CMS uses the ORM. The ORM itself is badass :-) CMS pages and plugins are structured in tree structures (via mptt or treebeard). This also translates into a heavily-customized admin changelist that renders as a tree.
Django CMS keeps a draft and a live version of each page. For each language. And titles are separate models. Also with draft/live. When going live with a page, various items need to be copied over draft to live and from a draft hiearchy into a live one. It are all database objects that have to point at each other where necessary. In this process they even sometimes set primary keys, which looked moderately scary. Quite scary, actually. It works though! And it has worked for many years.
The django ORM is very flexible and allows many tricks.
The ugly: the urlconf. There is no clean way to cleanly extend and customize the url resolver. Django needs it as it wants to integrate existing applications inside the url space of the CMS page tree.
They use apphooks to do this. You add an “apphook” plugin to a page and
thereby “mount” an existing django app under the page’s url. This needs some
serious urlconf trickery. It works by explcitly getting the available apphooks
and to extract urls from them and then to explicitly extend the urlpatterns in
your
urls.py.
Problem: the urlconf is read only once at django startup. And every time you add an apphook plugin, you’d have to restart django to get the extra urls in your urlconf! There is a partial solution for that now in the form of aldryn-apphooks-config which works on the basis of url namespaces.
An even better fix is the urlconf reload improvement done in version 3.2. It
uses a middleware that means one extra DB hit per request. If a change to the
urlhooks is detected, all the urlconf related modules are purged from
sys.modules…

Detaches a vmo from a pager.
#include <zircon/syscalls.h> zx_status_t zx_pager_detach_vmo(zx_handle_t pager, zx_handle_t vmo);
Detaching vmo from pager causes the kernel to stop queuing page requests for the vmo. Subsequent accesses that would have generated page requests will instead fail.
No new ZX_PAGER_VMO_READ requests will be generated after detaching, but some requests may still be in flight. The pager service is free to ignore these requests, as the kernel will resume and fault the threads that generated these requests. The final request the pager service will receive is a ZX_PAGER_VMO_COMPLETE request.
The kernel is free to evict clean pages from deregistered vmos.
TODO(stevensd): Update once writeback is supported.
pager must be of type ZX_OBJ_TYPE_PAGER.
vmo must be of type ZX_OBJ_TYPE_VMO.
zx_pager_detach_vmo() returns ZX_OK on success, or one of the following error codes on failure.
ZX_ERR_BAD_HANDLE pager or vmo is not a valid handle.
ZX_ERR_WRONG_TYPE pager is not a pager handle or vmo is not a vmo handle.
ZX_ERR_INVALID_ARGS vmo is not a vmo created from pager.

((discussion of UK and France laws around illegal content))
TimBL: I thought the distinction should be more like whether they perform editing
<noah> LMM: If legal community is using terms like hosting, transformation, etc., we could profitably define some of those in a document as a service to the community.
<noah> Isn't that already a stated goal of this document?
Larry: I"m not saying we should follow the legal opinion but we should look up the definitions used
<jar> dka: Let's not rathole
<noah> NOAH: We should mainly define terms as used in the technical community, but we should point out cases where we observe that confusingly different terminology or definitions are used by others.
noah: on cross-border we should point out how the terms are used in the community or on the web
Jeni: Section 1.1 has two bits on hosting:
Ashok: if our definitions are different from what the legal community use
<noah> LMM: Suggest a section, to be filled in, that explains where legal community uses terminology differently than we do in the rest of this document.
<noah> (I think Larry is proposing exactly what I proposed above)
TimBL: (discussing difference between ownership -- IPR -- separate from hosting )
... for online content, if you 'host' something do you 'possess' it?
... difficulty with use of 'possession'
<DKA> trackbot, start meeting
<trackbot> Date: 08 June 2011
Noah: equating 'hosting' with 'possession' leads to difficulty
<timbl> What Tim said was: The term 'posession' for physical artifacts combines aspect of ownership (as in property) and access to and control over -- but no such concept with these 3 wrapped up applies online.
noah: The organization of the document is surprising; you used a 'hote' for something that is really intended not as side commentary. editorially .... make the things now in notes into a separate section
<jar> Stallman says there is no such thing as "intellectual property"... meaning that you cannot possess bits, you can only possess a physical device that carries some bits. Copyright doesn't cover ownership, it covers copying and performing.
Jeni: I put them in notes because I wasn't sure we wanted them in there.
<timbl> Maybe it would be good say that some things are done by automatic agents, which are set up for various parties benefit but themselves cannot themselves be held responsible for the legality of the way they are used. These include transmission systems and routers, proxies, and also automatic format transfoamtion services and image re-rendering service, spell-checkers etc etc etc.
jar: The key idea is 'who is responsible for what'
TimBL: poeple who set up agents, format translation, spell checkers, image downsamplers, .... are not responsible for the content that those are used for.
ht: I like the note and think it should be upgraded, but point 2 is a tautology
... you should tell me things like 'things that are fundamental to their operation are at risk'
<jar> [ht is referring to 2nd bullet in note at end of 1.1]
Jeni: would it help with these to have the pithy 'this is the thing' first
<noah> Legislation that forbade transformations on illegal material would similarly limit the services that service providers could provide that are of value for legal purposes.
TimBL: while it would be great to have a list of automated agents as examples, it is important that, because this list changes all the time any laws should make the point in general about any automated systems like those, not the specific ones.
ashok: when you speak about transformations, you also include censorship
... censorship can be helpful in that it excludes bad words and then makes bad words acceptable
Jeni: is it useful to put in examples?
Noah: we should be particularly aware of international different concerns
<Ashok> Yes, examples would be great!
)
<noah> LMM: Then there are TAG recommendations on best practices. The terminology will stand; the examples are current
<noah> LMM: (scribe's not sure where that point was going) I like the Street View example.
<noah> LMM: Part of my question is "who is the audience for this document?" Just the legal community, or also ISPs?
<noah> LMM: So, I'm resisting wording suggesting what good laws would be, what the impact would be of laws, etc.
<noah> DKA: Genesis of this document was to service legal community's needs. Are you pushing back on that?
<jar> lmm's specific organization suggestion: 1. terminology 2. examples 3. recommended best practice
<noah> LMM: No, but rearrangement would help. Don't like the "if you were to do this it would be bad" should be "this happened, and it was bad"
<noah> LMM: Too speculative.
the wording sounds too speculative
terminology + organization
noah: I wouldn't go as far as Larry, in a document like this we should be careful how we shouldn't be to cautious
Jeni: Section 1.2 is around copying and distributing: 4 kinds of reasons why you copy data, with a summary and some points around that.
<noah> noah: I wouldn't go as far as Larry in being retrospective only. In some cases, it's very useful to say "we see certain policies being considered, we can explain the likely practical consequences to the Web"
<LMM> (example of terminology source)
noah: 1.2 I had to read this 2-3 times to understand
... there is a formal distinction between hosting "HOSTED OWNED CONTROLLED" by an 'origin server'. The intent here is fine but the presentation is unclear. Introduce the simple case and then add the complexity
... "it is usually impossible to tell" ... when? from just one perspective, not 'from a subpoena' ... in simple ways be more careful about stuff like that
DKA: we want to make sure this document is readable to non-technical people, perhaps a diagram would be useful?
(not sure 'non-technical' is the right audience)
<timbl> (Why we ended up with "origin server" instead of "original server" I don;t know)
('original' was updated with a new version, so it's not the original which used to be hosted at CERN etc.)
jar: talk about libraries?
noah: backup strategies might also make copies....
TimBL: backing up in the cloud ....
jar: I think it's worth talking about libraries... there is a special exception for them, that says libraries are allowed to make backups
Yves: do they have the right to own illegal content
<Larry> (historical note)
Yves: libraries may be able to hold on to illegal material even if they can't distribute it
Jeni: 1.2.3 Search engines
... 1.2.4 Reusing .... that's the bits you're after, if you're trying to prevent something.
DKA: you don't talk about 'fair use', and has different names
noah: I'd understand this if the terms lined up, and that we can clarify
... we have technical terms about transformation and storing and only indirectly allowed
... That is for the lawyers to do.... (examples about copying and Xerox machines)
larry: i'd suggest going through one more round and issue a FPWD
DKA: we should have Tinh back on and get his feedback on a call
... then we go to a more general community
Jeni: and Rigo .... and Casey (privacy council)
... get a legal review
jar: what Tinh said ... if this is a TAG finding, it will have some impact, but if it is Req track that would have broader review....
... it would have much broader impact
the people Tinh have in mind are judges, legislators, constituents, .... try to get EFF review
Noah: I do want to be careful about how we handle it
<jar> What the legal community will care about is whether the document has had wide review within the technical community. Rec track is W3C's usual way of getting wide review.
larry: encourage Jeni to make another editorial pass, get individual review, and then we'll mkae one more pass at the meeting, and then go to FPWD
<jar> +1
DKA: I tried to pull out section 1.5 with linking as a speech act. Essentially the idea is to conceptually put together linking with speech act, and put this into free speech
... freedom of expresion ... we htink linking is a kind of expression
larry: UN declaration last week on Internet
TimBL: there was a site that was taking down, who embedded video links
... drawing this lines is something the TAG could do
... cases where linking was aiding and abetting the crime
Jeni: linking to something is like speaking about something. Some cases there are are laws against some kind of speech ....
HT: suppose we agree as we have said many times that URIs are something like names. I'm not aware of any limitations on naming things, just ....
DKA: if you just had a list of links... and the combination of that list was, by itself, inciting violence
((heated conversation))
<ht> I really like the freedom of expression line
<ht> I am somewhat skeptical of the "subject to the same kind of constraints as any other kind of expression"
larry: We sometimes talk about the TAG saying things in this document, we should try to be careful that the TAG is editing this document but we're trying to capture community consensus
TimBL: you can say 'get your Free TV here', you're inciting people. If you say "here is how you can find out how ot make a bimb"
ht: A catalog of shops that used to sell the anarchist's cookbook isn't illegal even if the book itself is
timbl: when it comes to copyright, linking is fundamental, but when it comes to racial hate words might not be illegal
yves: we have laws in French about intent, indications of crime... is the link an invitation to follow the link... talking about what is legal or what is not legal
noah: one area that would be helpful to point out, there are different kind of links.... the visible rendering of the link where what is visible ...
((DKA brings up important use case of linking aka 'Rick Rolling'))
<jar> agree, a taxonomy of link presentations would help to tease out these issues
Noah: (( discussion of downloading pornography and case around that ))
<Zakim> ht, you wanted to mention hovertext
ht: could not find any tool that would that preserved hover text
<jar> ht: link presentation taxonomy interacts with tools (e.g. pdf combination) - taxonomy not invariant
.
<Yves> some tools generate links out of plain text (like MUAs)
noah: what i tried to do in the last few minutes is make a first cut on the product page for this work
((discussion of timeliness as a sucess criteria))
Ashok: I thought the goal was to help web hosting and product companies
jeni: there is an aspect to this that is about describing the technical things
jar: we want to help with their defense and prosecution
noah: I'm reluctant to delete what it says but augment it
jka: This document should be a useful tool for technical people to talk to lawyers
jar: Express the common understanding in the technical community to those who make law. That is what Thinh Nguyen said is needed and what the document does.
... In doing so we support the technical community
larry: I want the word consensus appear in the product page
... I would like the word 'consensus' to be part of the product page, our intention to build consensus, develop consensus
jar: 'make law'
((discussion of schedule, FPWD ....))
dka: we need a live legal review, don't think we can do it just by sending the document out
goal is to get legal feedback before next F2F
((discussion of agenda))
((break for 10 min))
((reconvene))
DKA: Review "Data Minimization in Web API"
... I was part of DAP working group call, was a good call, Frederick had sent me some good feedback and also from Robin and on more on the call.... also more feedback from others...
... They felt that this was a useful document for the TAG to produce
... I redid the introduction to be more clear. I renamed the document. Started with an excerpt of a 1978 paper...
dka: further on I extract the actual requirements that the DAP working group come up with ...
... talking about how this applies to geographic location
... what does this protect us from? Good feedback from DAP working group
... Section 2: what are our recommendation? This is something I just added. With some MUST and SHOULD and MAY language
... this tries to make this more general and clear
noah: people have seen earlier versions... who read this? Going over this for the benefit of what you did?
dka: I'd like to work on the product page for this... it's a smaller document, it's very targeted
... Noah, you asked "are there good examples of where this principle has been applied and it resulted in the desirable result? " and I don't know
noah: do you agree that this might have unintended consequences?
dka: there's been enough work on this that the risk is minimal, but we need more examples, and the document now lacks that
<noah>
((discussion of whether this should be req track))
((question about patent policy))
ashok: What are you thinking of oding to this?
dka: I want to add more references, get further review from a wider community....
... kind of TAG call for review
noah: tradition for findings is that we don't use a formal process, all the findings have previous versions... we send email to www-tag and other places...
jar: does this go out in weekly newsletter, it's important than it that happens
... the distinction between Finding and Req implies the kind of review we expect
<jar> ergo, the decision should be based largely on what kind of review we want
wonder if this is something we might do with IAB on privacy, covering not only APIs but also protocols
yves: tag findings are much like working group notes
noah: we never go through the W3C process
<jar> (for findings)
noah: this strikes me as being in the middle, we're just doing this for now
ashok: my reaction to this is that it is quite focused, and quite small, i would just publish this quick and get htis behind us
dka: the audience is mostly W3C people
... the date holds
yves: talking about reviews, might be a good coordination with IAB
<Zakim> masinter, you wanted to ask whether this might also apply to other data paths
dka: think that is already there in the action already
... want to work on this with IAB
noah: change the deliverables to have two parts... an informal publishing and then later a finding
dka: I would like to put out a draft finding for review ... before the next F2F sufficiently to have had some feedback com ein .... I think that means by the end of July
((discussion of schedule))
noah: DKA please edit the product page
... ... to include relevant actions and issues
ashok: there were two issues: sync with other devices, convert from other formats
... are there others?
noah: could you give more context, it seemed like there was a whole lot. There were issues with cookies, issues with permacookies. There are resources identified by URIs, there are caches on the local machine. My email might wind up on my issues.
... before you did the AJAX implementation....
timbl: Noah, is it is possible point to a piece of client-side state
noah: I believe people implement what we would view as a cache with AJAX that now loses the URI
... why is state indentified with the same URI
... When we do a finding asking we should combine cache/storage
ack
ashok: starts with discussion of cookies, you can't control them, got to client side storage, font stuff
... I tried to find apps where they use client-side storage
noah: mobile GMail... go into airplane can continue to read & write email
jar: used to be done with gears, now available with HTML storage
noah: they're using HTML client-side storage
ashok: "Oh gosh that's a terrific app, we couldn't have done that with cookies"
noah: you go to a web site and it starts eating space... you might want to clear for privacy reasons, it wrote a megabyte in my SD card?
... this thing looks great when you work on one site, but there's denial of storage
timbl: I've had something i've wanted for a while on tracking on dependencies, program space, debian keeps track of which modules were loaded
... I want to glob them
... ((example of how some app might help him manage storage on his device))
... installation and persistent cache should be treated on the same scale
noah: Tim wants really rich version of what 'manage local storage'
timbl: things like budgets for tasks
<Zakim> JeniT, you wanted to ask about encryption of data in local storage
ashok: doesn't say anything about encryption right now, sort of orthogonal
... consider encryption
whiteboard photo:
ashok: there's a reason why people don't encrypt but i don't know
<noah> NM: Encryption is an implementation technique used to achieve certain things...the document needs to start by stating what is to be achieved (that is, what are the threats against which we are protecting)
ashok: there are all these situations where people hack the cookies, encrypting them would prevent that
jeni: ((reporting examples came back on twitter))
... permissions around local storage, EU regulation that web sites have to talk about storage on local machine and what it's used for
<Zakim> noah, you wanted to talk about agenda item
ashok: this is the list, leading toward a product page
<JeniT> Other apps from twitter were from O'Reilly, FT webapp, facebook
<JeniT> Rigo references
<JeniT> Norm talks about
ashok: the idea is that W3C started in a new direction, going to this with local storage. The idea was to think about it, and say what are the questions it raises, how do we manage it, how do we use it.
noah: we need a product page
<JeniT> From @bsletten: These are all WebDB (which is WebKit-only) examples, some just tests:
ashok: you can have lightweight clients
larry: just want you to talk about iCloud and moving everything where the truth copy is in the cloud and everything is a cache in the architecture space
<JeniT> From @bsletten: Here is a full “application”:
<JeniT> From @bsletten: Here is an IndexedDB example:

Much of this session was spent filling in and re-prioritizing the TAG member assignments grid (source .xls ). We also reviewed and refined some of the corresponding TAG product pages.
noah: We need a better shared understanding of what we're trying to do in the next few months and who's working on what
... there are some things where I'd like that we do better
... [talks through spreadsheet of commitments of people to products]
... we get best output if people engage and collaborate on products
... it's healthy to have some things that are quality pieces of work that we can point back to
... the product pages help us to have a shared understanding of what we're doing
... are there a small number of these that we want to make sure we do well?
... ground rules for discussion: we won't spend time on technical issues regarding each product
... we won't expand or contract scope
timbl: Are new things out of bounds?
noah: We can look at adding those when we're comfortable with these
jar: there are six people, five of whom are working at capacity
... do people need to swap focus?
... how can we encourage those who aren't doing work to do more
noah: I want to break out of people working on their own
dka: some of the things don't seem to be equivalent levels
... privacy and dnt has different scope from publishing & linking on the web, which we know we're going to do
... we need to categorise and reflect topics, which reflect work
... such as Ashok going to the privacy workshop
noah: How much of the nuance between the things can we have? Hard in a spreadsheet.
... also the Xs don't indicate the depth of work someone is doing, it's very approximate
... let's try to do this mentally (to work out which are big and small)
... I really want to make broad groupings
timbl: If these things aren't the same, where's the problem?
... what we have to do *are* quite different in scope
dka: It doesn't matter; I think the problem is to reflect the amount of time that we're spending on each topic
timbl: should people fill that out themselves?
noah: I was hoping to start with the topic areas
dka: I'd like to see those categorised
noah: if I chose the three things to give high priority to, those things would be the ones that we'd really put intensive work on
... can we do all these without compromise
timbl: we need one piece of required reading for the telcon
noah: I want people to say which ones of these topics are the high priorities
timbl: HTML5 review is something that we should do
JeniT: some of these are time critical and others aren't
timbl: one for 'urgent' and one column for 'important'
noah: HTML5 gets a time critical code of 'Yes'
... Can we do this for others?
JeniT: fragid semantics is something that has a time critical component because it impacts on other drafts
ht: we identified that as something for TPAC 2011
Yves: I will work on fragid semantics as well
dka: I didn't say I'd do anything on fragid semantics
noah: We said we were starting the task force on HTML/XML unification
ht: I don't think we are the people to take this forward
noah: Having anything active on the list costs me effort
timbl: Make a priority column
noah: I'll add numbers for priorities
timbl: What is the objective for HTML/XML unification?
noah: it was to give the community guidance on how to maximise synergy between HTML and XML
timbl: I thought that was part of HTML5 review
... there's lots of things under HTML5 review, including fragid semantics
noah: the formal HTML5 review has to finish by early August
... there are links, and some aspects that we have to dive into early on
... that's currently top priority
timbl: that includes microdata and RDFa
noah: Can I continue to ask which things should be given priority?
ht: I'd like to give mime architecture for the web priority
... and HTTP semantics
... mime architecture is important because mime registrations are coming in all the time, and the longer we delay the more we miss
noah: high means that it should be within the top 5
timbl: why HTTP semantics?
ht: I want to prioritise what we talked about yesterday
noah: that might not be there
timbl: what is the urgency there?
<masinter> ISSUE-57?
<trackbot> ISSUE-57 -- Mechanisms for obtaining information about the meaning of a given URI -- open
<trackbot>
ht: it's our credibility, and because there's more linked data being published all the time
timbl: what's interesting for me is avoiding trainwrecks
jar: Add a column that captures why
[discussion on spreadsheet]
timbl: 'Finding URI definitions' important for linked data uptake & TAG credibility
... 'Fragid Semantics' is important for RDFa, which is part of our HTML5 review
... 'HTML/XML Unification' relates to HTML5 Review
noah: also we said we'd write something and we're close to shipping it
timbl: We need to schedule work to avoid the trainwrecks
noah: What about web application state? I'd like to argue for that one
JeniT: it's important and good and we're close but it's not time critical
noah: Web app state might be high priority because we're close with it
... I think the community would benefit from it
... We have to find what things fit in with the people who are working on it
dka: API minimisation and publishing and linking on the web are fairly high priority, but they're not 2s
noah: After sorting, our top priorities are HTML5 last call review, and to the bits of unification that relate to that
... to fragid semantics, web app state and Jonathan's work on URI definitions
... Have we lost anything? Are any of the rest high priorities?
ht: Let's ensure that one slot each week focus on things that aren't in the top priority list
noah: Yes, but there will be weeks where one or two things fill the call
... but we will get to the others too
... If the high priority ones aren't moving, then I'm going to get people to focus on them
... I want to cross check that people are working on the important ones
... there are roughly three groups: critical, things we intend to work on, and other random things
dka: some of these are things that we will work on when we clear the rest of the list
noah: we'll still work on some of these
dka: I don't know what 'privacy friendly web including do-not-track' is
noah: You helped make the product page for it
dka: I think privacy is an umbrella topic, that includes API minimisation etc
jar: these are things that we've decided we'll work on but we don't know exactly what we're going to do with them, this includes security and IETF
noah: I will pay attention to the product pages for these
... there might be new things that come in, and this will change
JeniT: One thing you were after was whether people needed to be moved to work on the important things
noah: OK, we're going to discuss HTML5 last call in a few minutes, and everyone will have to do something on it
... on fragid semantics we have JeniT, ht and Yves
... on web app state, we have Ashok
... I was asking ht
ht: I'd be much happier on Jonathan's papers
... if that's OK with Jonathan
noah: What's the product page for Jonathan's work?
JeniT: I volunteered on web application state
noah: 'Finding URI definitions' we have jar and ht
<jar>
on fragids I have done the product page:
noah: Larry, the next is mime architecture for the web, which was suggested as a priority
... it's in the IETF space, what do I need to do to make it happen better?
... is the energy that it will take low?
Larry: I don't expect a lot more TAG effort on it
... I have comments on it, I have a co-editor, I'll want some review, but I don't need a lot of TAG effort on it
noah: These high priorities are things that should take time
... I'll give myself an action to schedule a telcon of how to manage this over the next few months
Larry: Do you have a column on urgency? there's also how important it is, and how much effort is needed
ht: that comes back to HTML/XML unification, where there's nothing to do in the medium term
Larry: I'm expecting to review this with Alexei at the IETF meeting, and then I'd like to get TAG review then
noah: when is that roughly?
Larry: August
noah: On API minimisation, would it help for someone else to help you dka?
dka: I think it's small enough that it's ok just me
noah: Last one is linking & publishing
... that has JeniT & dka
... last one is HTML/XML unification
... I've asked Norm to get back to us with a document that needs TAG review
... Thank you, that has really helped me
<Norm> Will do. Need to get the TF to give it a once over and address comments, then will send along
noah: The other thing is that Jeff has asked for 2-3 things that we have said we would commit to
... How should I respond to Jeff?
timbl: Tell him about the top 5 things
noah: Isn't he after things that he can track in 2011?
timbl: Two or more things where we've got a schedule and milestones
<noah> ACTION: Noah to draft note for Jeff Jaffe listing 5 top TAG priorities as trackable items. [recorded in]
<trackbot> Created ACTION-568 - Draft note for Jeff Jaffe listing 5 top TAG priorities as trackable items. [on Noah Mendelsohn - due 2011-06-15].
ashok: He also wanted a list of stuff that he should be looking out for
noah: I took an action to figure out by fall how to respond to that
... OK, that ends this session
noah: We've decided to meet in Edinburgh in September
... are there any objections or anyone who can't attend?
[no one objects]
noah: what about the meeting afterwards?
... should it be in California in the winter
[preference and diary discussions]
noah: 4-6th January 2012?
... any strong preference between Cambridge & CA
... slight preference for Cambridge
<Yves> IETF is March 25-30, 2012 in Paris
<noah> RESOLUTION: The TAG will meet in Cambridge, MA 4-6 January 2012
<noah> ACTION: Noah to check with Peter on January TAG date [recorded in]
<trackbot> Created ACTION-569 - Check with Peter on January TAG date [on Noah Mendelsohn - due 2011-06-15].
<noah> ACTION: Noah to inform Amy of January TAG date [recorded in]
<trackbot> Created ACTION-570 - Inform Amy of January TAG date [on Noah Mendelsohn - due 2011-06-15].
<noah> RESOLVED: TAG members will hold 2-4 April 2012 for TAG meeting in Sophia Antipolis, France. The meeting is not yet confirmed. It's in order to ask for changes.
noah: A few people took actions to review sections
... Yves on security
... Larry has bug report on fragids
... Timbl on microdata mappings to RDF
... noah on normative status of author document
... Larry to draft note on TAG interest on architectural issues
... JeniT to review microdata and RDFa
... ht to review polyglot and DOCTYPES
... which of these do we want to discuss?
<noah> * Better ways of asking chairs about HTML5 architural issues
<noah> * Microdata and RDFa
<noah> * Authoring draft status
<noah> * App cache (Dan)
<noah> PLH: Last call ends August 3.
<noah> * Do we have enough coverage?
Larry: plh, there's a last call, how do you think the TAG could be most effective?
plh: you don't have to review the entire specification
... the list you have is a good one
... the URI/IRI issue is one
Larry: the TAG has a charter to resolve issues between working groups, so perhaps we can be more involved with that more than reviewing documents
plh: the biggest issue we have there is between HTML and WAI-PF
Larry: Do we need higher consideration?
jar: Have you heard from RDFa?
plh: Well, that's part of the group to some extent
ht: the crucial thing, namely prefix bindings, went away as they're still there
<masinter> ht: xmlns prefixes are in the HTML draft? Plh says no.
plh: are you talking about HTML5 syntax for xmlns?
jar: Prefixes is part of it, but microdata is another part of it
... is there any issue between the RDFa WG and microdata?
plh: not recently
noah: Larry made the point that we're here to resolve issues within WGs
... we also have a mandate to help ensure that specs use web architecture well
... we should continue to do that even if WGs don't come up with objections
Larry: one of the chairs of the WG believes that the TAG has no authority
timbl: the TAG is considered just as any other member of the group
noah: can we scope the issues and if that becomes a problem we'll worry about it then
timbl: What were the issues that we had?
noah: There were a few, didn't we have a discussion and send an email that listed those points?
<timbl> - Microdata and RDFa conflict
<timbl> - historically, URI spec
<timbl> - historically, HTTP spec
plh: There is issue 41 on decentralised extensibility
... the group made a decision, and no one is arguing against it
ht: xml-dev woke up to this 10 days ago
<masinter>
noah: We had the HTML/XML unification work which is part of that
<plh> --> HTML5 and almost no namespaces
noah: If we've given our input, is it appropriate to raise the issue again at last call?
plh: you can provide new material, or you can raise an objection
<DKA> Isn't this why we encouraged development of the Polyglot spec?
timbl: someone asked how you put Exhibit stuff into HTML5 so that it will validate?
<masinter> how does issue-41 work with polyglot?
plh: The answer is XHTML syntax
noah: XHTML syntax or polyglot?
plh: when you use namespaces in XML syntax, they are valid there, but they might not load properly in the DOM
... if you use application/xhtml+xml then it will be loaded properly in the DOM
... just not in text/html
noah: a script will find it when parsed as XHTML, but not when parsed as HTML
... is there news on polyglot?
plh: we have objection on making it normative
... separate from the authoring spec
dka: what is the objection?
noah: the objection on authoring & base spec normative is potential for clashes
... the polyglot spec doesn't redefine anything, it just observes what works in both modes
timbl: it's only an observation
<masinter> should polyglot reference the authoring spec instead of the main one
<plh> --> Polyglot spec should be a Note
dka: the implication of polyglot is that there is an implementation burden on browsers, isn't there?
plh (etc): no
noah: it's just says where the parsing rules intersect to yield the same DOM or other interestingly compatible results
<plh>
timbl: the polyglot spec should be considered a rec track spec
plh: we have someone objecting to that right now
noah: you can have rec track but non-normative
... if this spec disagrees with a normative spec, then it's clear which is in error
... if you have two normative specs that don't work together then it's hard to work out where the bug is
Larry: we should specify what a normative spec is and why you would want one
<masinter> why you might or might not want it
ht: the issue was raised to get rid of prefix bindings, a change proposal against RDFa in HTML
... there were two change proposals in response to this issue (120)
... one was to take out profile/prefix/xmlns
<plh> --> Use of prefixes is too complicated for a Web technology
<noah> HTML WG Decision on their ISSUE 120:
ht: the other was to say that it's important, with existing pages containing xmlns, and you can't take it away
... eventually the chairs found in favour of the status quo
... so RDFa as currently constituted has prefixes and CURIES and uses xmlns to bind them
... despite the fact that HTML doesn't support namespace bindings
JeniT: I've implemented building RDFa processor over HTML and it sucks
ht: various people want to reopen the issue
<plh> --> New Information Status
ht: but the chairs won't reopen until there's substantial new information
... and there is no formal request to reopen
noah: how we should engage is tricky
Tim: observation about RDFa and microdata...
Noah: What do we currently have scheduled for TAG work on that issue?
... Henry?
HT: That one's not on me but it is on someone.
JAR: I had a concrete suggestion on RDFa.
<ht> Here's the nub of the mess that text/html + RDFa + xmlns:... requires, given no support for xmlns:... in the HTML5 DOM:
jar: the suite of HTML5 specs talk about both microdata and RDFa and creating RDF from them
... and the way they do it is qualitatively very different
... the microdata mapping is done by the HTML WG
... the HTML+RDFa document is developed cooperatively between HTML and the RDF applications WG
... I or JeniT should take an action to point this out to the RDFa/RDF WG chairs
... I think the mapping to RDF should be the business of the people involved in RDF
... maybe the process was fine, maybe if they cared, there would be formal objections
... I want to check with Manu and others whether they're happy with it
... the potential change proposal would be to remove that section
noah: the time is limited between now and early August
... if we want to have impact, we need to get to the point where if we want to, we need to raise a formal objection
... we need to focus on that level of things
Larry: Having these two specs for doing this is architecturally wrong
... we can see how this battles out in the market place
... perhaps we should ask the microdata and RDFa specs should be declared not ready to go to Rec until there's more work on getting them to work together
<noah> ACTION-367?
<trackbot> ACTION-367 -- Noah Mendelsohn to ask the HTML5 chairs to treat our 8220 bug as input to the poll, specifically as "An objection to keeping Microdata in", cc to www-archive@w3.org -- due 2010-02-10 -- CLOSED
<trackbot>
Larry: it's harmful having two
<Zakim> masinter, you wanted to wonder that moving RDFa and microdata forward is a really unhappy overlap, that schema.org is 'more information', and maybe microdata / RDFa should be worked on further, and LC is premature
<ht> Some real numbers about RDFa:
noah: we previously had actions on microdata
... there was a history of prior pushback on microdata
ht: they responded positively to that
<ht> In that they moved it out of the main spec.
plh: I don't think that stopping going to Rec is going to have much effect
... people are already doing it
... you have to formally object early
... maybe we should consider creating a task force to reconcile the two
... like we did for HTML/XML
timbl: people see this as tribal war between those who like/dislike RDF
... a task force isn't just about these specs, but about the communities behind them
... you can imagine reinvention of schema languages, query languages for microdata
... I'm not biased towards RDFa because I'm an RDF-head, but because it's compatible with a set of technologies developed over many years
... and has companies invested in it
... not necessarily the browser vendors
<masinter> the TAG work on metadata architecture is part of this
timbl: this isn't just about two specs
... and if there are issues of usability, the RDFa spec should change too
JeniT: I looked through microdata and rdf specs.
... the big things that jumped out as being problems to me
... a) the stuff Jonathan touched on - the incompatibilities of what you get when you parse each of them
<noah> Hmm, so you can't use them both in the same document?
JeniT:.
... so there is a mismatch between them, a conflict between them (you can't use them both)...
... If you're going to have 2 ways of doing the same thing then they ought to have clear advantages and disadvantages in different circumstances, and a clear upgrade path from the simple one to the complex one.
HT: They ought to be complementary.
<Zakim> noah, you wanted to ask how task force relates to last call comments
noah: I wanted to ask if, if we create a task force, how does that fit with August last call
ht: a report from such as task force would provide new evidence
<Zakim> ht, you wanted to mention a simple metric which supports Jeni
noah: we need to say something now about this, to lay groundwork
<noah> HT: The new evidence might apply to a subsequent last call.
ht: the extracting microdata to JSON section is one screenful compared to five screenfuls to RDF
<noah> NM: Hmm, it might uncover new input, but shouldn't we also see how much input we can provide for >this< last call?
plh: There is a long example in the RDFa section, but no example in the JSON section
... This issue has never been brought to the working group
... the issue of working on two data specifications has never been discussed
ht: Tim's objection was that microdata should be taken out
<ht>
<Zakim> masinter, you wanted to ask if we want to work on Jeni's comments
Larry: JeniT had some comments
JeniT: I can write those up
<scribe> ACTION: JeniT to write up comments on microdata and RDFa [recorded in]
<trackbot> Created ACTION-571 - Write up comments on microdata and RDFa [on Jeni Tennison - due 2011-06-15].
Larry: I like this idea of a task force
noah: it wouldn't have input to this last call
Larry: We can comment that the specs shouldn't progress until the task force reports back
noah: We need to make a case that something is broken
<masinter> because there are two ways of doing the same thing that are inconsistent
noah: can we object to things in 2nd last call that are unchanged?
ht: yes!
noah: we could file an objection now with crude form on issues, and say we think it needs more detailed attention
... can we draft a last call comment?
timbl: an alternative is to object just to microdata
[discussion about status of RDFa as existing Rec]
ht: I only want to object to microdata
... RDFa is standardising a widely deployed technology that we already have standardised
jar: there are legitimate parties who have reviewed RDFa who have said it's not acceptable
timbl: How can we say that RDFa should have those issues addressed?
jar: the issue is reconciliation not one spec or the other
yves: in '95 when we had CSS, SGML had DSSSL
... CSS was adopted because it was easy enough, despite the conflict
ht: it was agreed between the CSS and XSL that they would share a common semantics
yves: it would be fine if there was no conflict between the two
... that being the case, the objection is to the two unless we have a good story to tell
noah: do we have to object on a per-document basis?
... can we object on the package of HTML5 rather than on a particular document
timbl: I'm not sure of the process, but yes that would be appropriate
Larry: we can object to each of them because they're in conflict
... if we had to choose one it would be microdata
... we think they're both likely to be forward, and what we want is consistency in the upgrade path
timbl: microdata and RDFa are identical except for spelling differences
... microdata may be a subset
... it's at the same level, not like CSS vs XSL
JeniT: there are large and complex differences in whether something is an item, the rules in RDFa are complicated
... RDFa tried too hard to fit naturally into existing pages and this makes it really difficult to process and author
noah: we can't reinvent RDFa based on this experience because it would take too long
JeniT: fixing RDFa might not take too much time if they break backwards compatibility
timbl: there is a lot of RDFa out there already
JeniT: I will take what I'm writing and couch it as an objection
dka: we didn't cover appcache
plh: my only point was Yves should look at it
<masinter> Chris Weber new IRI chair was communicating with HTML-WG directly
<masinter> plh, suggest you follow up with Chris Weber on the HTML/IRI issues, I'm encouraging him to push forward on issues

pututline()
Write an entry in the user-information file
Synopsis:
#include <utmp.h> void pututline( struct utmp * __utmp );
Since:
BlackBerry 10.0.0
Library:
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
This function is in libc.a, but not in libc.so (in order to save space).
Description:
The pututline() function writes out the supplied utmp structure into the utmp file.
It uses getutid() to search forward for the proper place if it finds that it isn't already there. Normally, you should search for the proper entry by calling getutent(), getutid(), or getutline(), If so, pututline() doesn't search. If pututline() doesn't find a matching slot for the new entry, it adds a new entry to the end of the file.
When called by a non-root user, pututline() invokes a setuid() root program to verify and write the entry, since the file specified in _PATH_UTMP is normally writable only by root. In this event, the ut_name field must correspond to the actual user name associated with the process; the ut_type field must be either USER_PROCESS or DEAD_PROCESS; the ut_line field must be a device-special file and be writable by the user. | http://developer.blackberry.com/native/reference/core/com.qnx.doc.neutrino.lib_ref/topic/p/pututline.html | CC-MAIN-2017-34 | refinedweb | 207 | 64.61 |
Hey,
I am trying to make a program that would first read a text file or a excel file and store two types of data, a line start and a line width. I than want the program to scan a new text file and using the data it stored from the other files to store the data. An example, like the file has line start of 5 and width of 4 I want the program to then go into the other text file and go to line 5 then copy everything from line 5 to line 9. Then once it copes all the data what was listed from the first file, I want it to create an output of all the data that it copied.
My question is, how can I go about making the program copy the content at line 5 to line 9, even if it is a space?
As of right now, I have some old program I used to analyze data that would scan the first 49 numbers and do some calc.
here is the class from the old code that I want to modify. My idea was to change it so that it would store the first text file or excel file into a hash table where the key would be line start and and data would the the width. Than it would scan the other file and spit out an output in a text file or something.

I’m currently working on a project where we started using PageTypeBuilder after a refactoring process. We had some dynamic properties we needed to make available. I therefore made a hack around PTB that includes support for dynamic properties.
The concept is easy. In your top PageType base class you add an attribute. Then you tag up your properties but use Dynamic Property instead of PageTypeProperty
[DynamicPropertyContainer] public class BasePageData : TypedPageData { [DynamicProperty] public string JavaScript { get; set; } }
The code will find all class's tagged with DynamicPropertyContainer and find all properties in those classes tagged with DynamicProperty. If it finds 2 properties with the same name it will skip the last one :)
In front code you can of course use
<%=CurrentPage.JavaScript%>
I’,m using the version of PTB that is compailed for CMS 5, so it could maybe be some change in the CMS 6 version. But I needed to copy some code to my own project cause use of internal and private… (sorry couldn’t resist:) ).
The code is available as 4 cs files, and 1 dll.
Quick Tip
Some times you need to access the property instead of the underline object that PageTypeBuilder returns. So if you make a class like this
public static class ClassInfo<T> { public static string GetName<R>(Expression<Func<T, R>> expr) { var node = expr.Body as MemberExpression; if (object.ReferenceEquals(null, node)) throw new InvalidOperationException("Expression must be of member access"); return node.Member.Name; } }
Then you can access the property like this
CurrentPage.Property[ClassInfo<BasePageData>(p=>p.JavaScript)]
Hi Anders!
You could use the GetPropertyName extension method that ships with PTB to accomplish what you do with the ClassInfo class.
It should also be added that while PTB doesn't support creating dynamic properties you can use it to access their values in a strongly typed way.
For more about why PTB doesn't support adding dynamic properties and how to use it to access their values see.
Hi Joel
Thanks for the tip on GetPropertyName
The reason for this code is to ensure that the dynamic properties are created. That’s one of the huge benefits of PTB also. That’s way I used the same concept to create the properties.
If PTB should support dynamic properties is totally up to you, but I see benefit of automatically created dynamic properties. I have to say that I also like dynamic properties as a concept, and are not a huge fan of inherit properties thou the page tree.

Previewing Running Applications in the AWS Cloud9 Integrated Development Environment (IDE)
You can use the AWS Cloud9 IDE to preview a running application from within the IDE.
Run an Application
Before you can preview your application, it must be running on the correct port and IP in the AWS Cloud9 development environment.
Be sure to run on port
8080 and use the IP of
localhost or
127.0.0.1.
To write the code to run your application on this port and IP, see your application's documentation.
To run your application, see Run Your Code.
To test this behavior, for example you could add the following JavaScript code to
a file with a name such as
server.js in the root of your environment. This code
runs a server using Node.js, as follows.
Copy
var http = require('http'); var fs = require('fs'); var url = require('url'); http.createServer( function (request, response) { var pathname = url.parse(request.url).pathname; console.log("Trying to find '" + pathname.substr(1) + "'..."); fs.readFile(pathname.substr(1), function (err, data) { if (err) { response.writeHead(404, {'Content-Type': 'text/html'}); response.write("ERROR: Cannot find '" + pathname.substr(1) + "'."); console.log("ERROR: Cannot find '" + pathname.substr(1) + "'."); } else { console.log("Found '" + pathname.substr(1) + "'."); response.writeHead(200, {'Content-Type': 'text/html'}); response.write(data.toString()); } response.end(); }); }).listen(8080, 'localhost'); // Or '127.0.0.1' instead of 'localhost'.
Or you could add the following Python code to a file with a name such as
server.py in the root
of your environment. This code runs a server using Python, as follows.
Copy
import os import SimpleHTTPServer import SocketServer ip = 'localhost' # Or '127.0.0.1' instead of 'localhost'. port = '8080' Handler = SimpleHTTPServer.SimpleHTTPRequestHandler httpd = SocketServer.TCPServer((ip, int(port)), Handler) httpd.serve_forever()
Next, add the following HTML code to a file with a name such as
index.html in the root of your environment.
Copy
<html> <head> <title>Hello Home Page</title> </head> <body> <p style="font-family:Arial;color:blue">Hello, World!</p> </body> </html>
To see this file's HTML output on the application preview tab, run
server.js with Node.js or
server.py file with Python.
Then follow the instructions in the next procedure to preview it. On the application
preview tab, add
/index.html to the end of the URL, and then press
Enter.
Preview a Running Application
With your application already running on the correct port and IP address in the environment, as described in the previous section, and with the corresponding application code file open and active in the AWS Cloud9 IDE, choose one of the following on the menu bar:
Preview, Preview Running Application
Tools, Preview, Preview Running Application
This opens an application preview tab within the environment, and then displays the application's output on the tab.
Note
If the application is not already running, you will see an error on the application preview tab. Run or restart the application, and then choose the menu bar command again.
The Preview Settings menu on the application preview tab is currently not functional, and choosing any of its menu commands will have no effect.
Reload an Application Preview
On the application preview tab, choose the Refresh button (the circular arrow).
Note
This command does not restart the server. It just refreshes the contents of the application preview tab.
Change the Application Preview Type
On the application preview tab, choose one of the following in the preview type list:
Browser: Previews the output in a web browser format.
Raw Content (UTF-8): Attempts to preview the output in Unicode Transformation Format 8-bit (UTF-8) format, if applicable.
Markdown: Attempts to preview the output in Markdown format, if applicable.
Open an Application Preview in a Separate Web Browser Tab
On the application preview tab, choose Pop Out Into New Window.
Note
The application preview will not be displayed in a separate web browser tab unless the AWS Cloud9 IDE is also running in at least one other tab in the same web browser.
Switch to a Different Preview URL
On the application preview tab, type the path to a different URL in the address bar. The address bar is located between the Refresh button and the preview type list.
Share a Running Application over the Internet
After you preview your running application, you can make it available to others over the internet.
To do this, if you have an AWS Cloud9 SSH development environment, see your server's documentation. For an EC2 environment, do the following:
Step 1: Set Up Your Environment with Your AWS Access Credentials
In the next step, you use the AWS Command Line Interface (AWS CLI) in your AWS Cloud9 development environment to open a port for the running application. To do this, the AWS CLI in your environment needs access to your AWS access credentials. If you have already set up your environment with your credentials, skip ahead to Step 2: Open the Port for the Running Application.
You can set up your environment with your AWS access credentials by using approaches such as the following:
If you are using an EC2 environment, AWS managed temporary credentials are set up in your environment by default. AWS managed temporary credentials handles AWS access credentials on your behalf for the AWS CLI to use.
If you are using an EC2 environment, and for some reason you cannot use AWS managed temporary credentials, attach an IAM instance profile to the Amazon EC2 instance that connects to your environment. This instance profile manages temporary credentials on your behalf for the AWS CLI to use.
Store your permanent AWS access credentials within the environment. For example, you can do this by running the
aws configurecommand or by setting custom environment variables.
For more information, see Call AWS Services from an Environment.
Step 2: Open the Port for the Running Application
To open the port for your running application, in a terminal session in your environment,
use the AWS CLI to run
the following two commands:
describe-instance and
authorize-security-group-ingress.
First, run the Amazon EC2
describe-instance command to get the ID of the Amazon EC2 security group
that is attached to your Amazon EC2 instance. Replace
MY_ENVIRONMENT_NAME with the name
of your environment. This command outputs the security group ID.
Copy
aws ec2 describe-instances --filters "Name=tag:Name,Values=*MY_ENVIRONMENT_NAME*" --query 'Reservations[*].Instances[*].SecurityGroups[*].GroupId' --output text
Note that in the preceding command, if you have more than one environment with the same name, multiple security group IDs may be output. In this case, you may want to use the Amazon EC2 console to try to get the correct security group ID. For more information, see Describing Your Security Groups in the Amazon EC2 User Guide for Linux Instances.
Second, run the Amazon EC2
authorize-security-group-ingress command as follows to open port 8080 to everyone, replacing
MY_SECURITY_GROUP_ID with
the security group ID output by the previous command.
Copy
aws ec2 authorize-security-group-ingress --protocol tcp --port 8080 --cidr 0.0.0.0/0 --group-id MY_SECURITY_GROUP_ID
Note
Setting
--cidr to
0.0.0.0/0 provides broad access to this Amazon EC2 instance. Use this setting only for experimentation
purposes.
If successful, no errors and no confirmation message will be output.
Step 3: Change the Running Application IP
In your code, switch from using IP
127.0.0.1 or
localhost to using IP
0.0.0.0. To use this new IP, run the application again,
if it was not already running.
Step 4: Distribute the Running Application URL
With the application running, in the menu bar in the AWS Cloud9 IDE, do one of the following:
Choose Window, Share.
Choose Share (located next to the Preferences gear icon).
In the Share this environment dialog box, in the Links to share area, give the URL in the Application box to those whom you want to view your running application.
Note
You may need to change the URL to start with of
https://. Also, you may need to add
:8080to the base URL. Otherwise, going to the preceding URL might show an error. | https://docs.aws.amazon.com/cloud9/latest/user-guide/app-preview.html | CC-MAIN-2017-51 | refinedweb | 1,360 | 56.76 |
Thanks Stepan! I did think about putting in the conditional in configure.in/.ac but even though it can be arranged so that it will be known at configure time what build is preferred I do not want to implement it this way (essentially this will require us to use two different configure.ac files to generate the makefiles the way things are set up here). I would rather pass in the build type during "make". Are there any other options?

How to Execute Mars in a Distributed Manner
We have already introduced what Mars is in a previous article, and have made it open source on GitHub after testing it on our internal systems. This article introduces the distributed execution architecture implemented by Mars.
Architecture.
Submitting a Job
The client submits jobs to the Mars service through the RESTful API. The client writes the code on the tensor, and then converts the tensor operation into a graph composed of tensors through
session.run(tensor) and submits it to the web API. After that, the web API submits the job to the SessionActor and creates a GraphActor in the cluster for graph analysis and management. The client starts to query the execution state of the graph until the execution ends.
In the GraphActor, we convert the tensor graph into a graph composed of operands and chunks according to the chunks settings first. The process enables the graph to be further split and executed in parallel. Afterwards, we conduct a series of analyses on the graph to obtain the priority of operands and assign workers to the starting operand. For details about this part, see the section “Prepare the execution graph”. Then, each operand creates an OperandActor to control the specific execution of the operand. When the operand is in the
READY state (as described in the
Operand state section), the scheduler selects the target worker for the operand, and then the job is submitted to the worker for actual execution.
Controlling the Execution
When an operand is submitted to a worker, the OperandActor waits for a callback on the worker. If the operand is executed successfully, the successor for the operand is scheduled. If the operand fails to execute, the OperandActor tries several times. If it still fails, the execution is marked as failed.
Canceling a Job
Clients can cancel running jobs using the RESTful API. The cancel request is written to the state storage of the graph, and the cancel interface on the GraphActor is called. If the job is in the preparation phase, it ends immediately after the stop request is detected, otherwise the request is sent to each OperandActor and the state is set to CANCELLING. If the operand is not running at this time, the operand state is directly set to CANCELLED. If the operand is running, the stop request is sent to the worker and causes an ExecutionInterrupted error, which is returned to OperandActor. At this time, the operand state is marked as CANCELLED.
Preparing the Execution Graph
When a tensor graph is submitted to the Mars scheduler, a finer-grained graph composed of operands and chunks is generated according to the chunks parameters contained in the data source.
Compressing a Graph
After the chunk graph is generated, we scale down the size of the graph by fusing the adjacent nodes in the graph. This fusing also enables us to make full use of accelerated libraries, such as numexpr, to accelerate the computation process. Currently, Mars only fuses operands that form a single chain. For example, when the following code is executed:
import mars.tensor as mt
a = mt.random.rand(100, chunks=100)
b = mt.random.rand(100, chunks=100)
c = (a + b).sum()
Mars fuses the ADD and SUM operands into a FUSE node. Rand operands are not fused, because they do not form a simple straight line with ADD and SUM.
Allocating an Initial Worker
It is critical to allocate workers to operands for the performance of the graph execution. Random allocation of initial operands may result in huge network overhead and imbalance of job allocation among different workers. The allocation of non-initial nodes can be easily determined according to the physical distribution of the data generated by its precursor and the idle state of each worker. Therefore, in the preparation phase of the execution graph, we only consider the allocation of initial operands.
We should follow several principles for initial worker allocation. First, the operands allocated to each worker needs to be balanced as much as possible. This enables the computing cluster to have a higher utilization rate during the entire execution phase, which is especially important in the final phase of execution. Second, the initial node allocation requires minimal network traffic when subsequent nodes are executed. In other words, the initial node allocation should fully follow the locality principle.
It should be noted that the principles above may conflict with each other in some cases. An allocation solution with minimal network traffic may be very skewed. We have developed a heuristic algorithm to obtain the balance between the two goals. The algorithm is described as follows:
- The first initial node and the first machine in the list are selected;
- In the undirected graph converted from the operand graph, depth-first search is started from the node;
- If another unallocated initial node is accessed, we allocate it to the machine selected in step 1;
- When the total number of operands accessed exceeds the average number of operands accepted by each worker, the allocation is stopped;
- If there are still workers who have not been allocated operands, go to step 1. Otherwise, the computation ends.
Scheduling Policy
When a graph composed of operands is executed, an appropriate execution sequence reduces the amount of data temporarily stored in the cluster, thus reducing the possibility of data being dumped to disk. An appropriate worker can reduce the total network traffic during execution.
Selection Policy for Operands
An appropriate execution sequence can significantly reduce the total amount of data temporarily stored in the cluster. The following figure shows an example of the Tree Reduction. The circles represent operands, the squares represent chunks, red represents the operand is being executed, blue represents the operand can be executed, green represents the chunks generated by the operand have been stored, and gray represents the operand and its related data have been released. Assuming that we have two workers and each operand uses the same amount of resources, each figure below shows the state after 5 time units of execution under different policies. The figure on the left shows that the nodes are executed according to the hierarchy, while the figure on the right shows that the nodes are executed in order of depth-first priority. The data of 6 chunks needs to be temporarily stored in the left graph, while the data of only 2 chunks needs to be stored in the right graph.
Our goal is to reduce the total amount of data stored in the cluster, so we have set a priority policy for operands in the READY state:
- Operands with a larger depth need to be executed first;
- Operands, which are relied upon by deeper operands, needs to be executed first;
- Nodes with smaller output sizes need to be executed first.
Selection Policy for Workers
When the scheduler is ready to execute the graph, the worker of the initial operand has been determined. We allocate workers for subsequent operators based on the worker where the input data is located. If a worker has the largest input data size, the worker is selected to execute subsequent operands. If there are multiple workers with the same input data size, the resource state of each candidate worker plays a decisive role.
Operand State
Each operator in Mars is separately scheduled by an OperandActor. The execution process is a process of state transition. In the OperandActor, we define a state transition function for the process of entering each state. The initial operand is in READY state during initialization, while the non-initial operand is in UNSCHEDULED state during initialization. When the given conditions are met, the operand is transitioned to another state and the corresponding operations are performed. The process of state transition can be seen in the following figure:
The following describes the meaning of each state and the operations performed by Mars in these states.
- UNSCHEDULED: An operand is in this state when its upstream data is not ready.
- READY: An operand is in this state when all upstream input data is ready. After it enters this state, the OperandActor submits jobs to all workers selected in the AssignerActor. If a worker is ready to run a job, it sends a message to the scheduler. The scheduler sends a stop message to other workers, and then send a message to the worker to start the job execution.
- RUNNING: An operand is in this state when its execution has been started. When it enters this state, the OperandActor checks whether the job has been submitted. If not, the OperandActor constructs a graph composed of FetchChunk Operands and the current operand, and submits it to the worker. Afterwards, the OperandActor registers a callback in the worker to obtain the message indicating that the job is completed.
- FINISHED: An operand is in this state when the job is completed. When an operand enters this state and has no successors, a message is sent to the GraphActor to determine whether the execution of the entire graph has ended. At the same time, the OperandActor sends a message to its precursors and successors that the execution is completed. If a precursor receives the message, it checks whether all the successors have been completed. If so, the data on the current operand can be released. If a successor receives the message, it checks whether all the precursors have been completed. If so, the successor state can be transitioned to READY.
- FREED: An operand is in this state when all its data has been released.
- FATAL: An Operand is in this state when all attempts to re-execute fail. When an operand enters this state, it passes the same state to the successor node.
- CANCELLING: An operand is in this state when it is being canceled. If the job is currently executing, a request to cancel execution is sent to the worker.
- CANCELLED: An operand is in this state when the execution is canceled and stopped. If the execution enters this state, the OperandActor attempts to transition the state of all successors to CANCELLING.
Execution Details in Workers
A Mars worker contains multiple processes to reduce the impact of GIL on execution. The specific execution is completed in an independent process. To reduce unnecessary memory copying and inter-process communication, a Mars worker uses shared memory to store execution results.
When a job is submitted to a worker, it is first placed in a queue waiting for memory allocation. When the memory is allocated, the data on other workers or the data that has been dumped to the disk on the current worker is reloaded into the memory. At this point, all the data required for computing is already in the memory, and the actual computing process is ready to start. When the computation is completed, the worker puts the job into shared storage. The transition relationships of the four execution states are shown in the figure below
Controlling the Execution
A Mars worker controls the execution of all operators in the worker through an ExecutionActor. The actor itself is not involved in actual operations or data transfers, and only submits tasks to other actors.
The OperandActor in the scheduler submits jobs to the worker through the
enqueue_graphcall on the ExecutionActor. The worker accepts the submission of operands and caches it in the queue. When the job can be executed, the ExecutionActor sends a message to the scheduler, which determines whether to execute the operation. When the scheduler determines to execute the operand on the current worker, it calls the
start_executionmethod and registers a callback through
add_finish_callback. This design allows execution results to be received at multiple locations, which is valuable for fault recovery.
The ExecutionActor uses the
mars.promise module to process execution requests from multiple operands simultaneously. The specific execution steps are linked through the "then" method of the Promise class. When the final execution result is stored, the previously registered callback is triggered. If an error occurs in any of the previous execution steps, the error is passed to the handler function registered by the catch method and processed.
Sorting of Operands
All operands in the READY status are submitted to the worker selected by the scheduler. Therefore, for most of the execution time, the number of operands submitted to the worker is usually larger than the total number of operands that a worker can handle. The worker needs to sort the operands and then select some of them to execute. This sorting process is performed in the TaskQueueActor, which maintains a priority queue that stores information about the operands. At the same time, the TaskQueueActor regularly runs a job allocation task, allocating execution resources for the operands in the top of the priority queue until there are no additional resources to run operands. This allocation process is also triggered when a new operand is submitted or when the execution of an operand is completed.
Memory Management
A Mars worker manages two aspects of memory. The first part is the private memory of each worker process, which is held by each process itself. The second part is the memory shared by all processes, which is held by plasma_store in Apache Arrow.
To avoid process memory overflow, we have introduced a worker-level QuotaActor to allocate process memory. Before an operand starts executing, it sends a batch of memory requests to the QuotaActor for input and output chunks. If the remaining memory space can meet the request, the request is accepted by the QuotaActor. Otherwise, requests are queued to wait for free resources. When the relevant memory is released, the requested resources are also released. At this point, the QuotaActor can allocate resources to other operands.
The shared memory is managed by plasma_store, which usually takes up 50% of the total memory. There is no possibility of overflow, so this part of memory is allocated directly through the relevant plasma_store method without going through the QuotaActor. When the shared memory is used up, the Mars worker tries to dump some unused chunks to the disk to free up space for new chunks.
The data in chunks dumped from the shared memory to the disk may be reused by subsequent operands, while reloading the data from the disk into the shared memory may be very IO resource-intensive, especially when the shared memory is exhausted and other chunks need to be dumped to the disk to accommodate the loaded chunks. Therefore, when data sharing is not needed (for example, the chunk is only used by one operand), we load the chunk directly into the private memory of the process, instead of the shared memory. This can significantly reduce the total execution time of the job.
Future Work
Mars is currently undergoing rapid iteration. We are considering implementing the worker-level failover and shuffle support in the near future, and scheduler-level failover is also in planning.

Differences between Abstract class and Interfaces
This article explains major differences between Abstract class and Interfaces with example program
Introduction
In almost all interviews everybody will face atleast one question which I mentioned in the following.
1)What is abstract class?
2)What is Interface?
3)Differences between Abstract class and Interfaces?
The article which I am giving will clearly explains you these three questions. Please read and compare all the comments which I mentioned in the program carefully. You can easily answer these three questions.
Abstract Class Program
Here I am going to explain Abstract class program with simple example, In this program I commented some lines Please read one by one very carefully to get an idea of abstract calss. My explanation with simple program because everybody can get the basic idea of abstract class.
abstract class aaa
{
//In abstract class a method must be declared as abstract.
//For abstract methods there will be no body i.e. There is no implementation.
//The Abstract methods can delare with Access modifiers(public,internal,protected etc )But
//when implementing in subclass same access modifier we have to use.
abstract public void pqr();
//The Abstract class can contain variables and concrete methods.
public int i;
public void abc()
{
}
}
//A class can Inherit only one Abstract class i.e Multiple inheritance is not possible here
class bbb : aaa
{
//we have to must and should call all the abstract methods in the derived class.
//To implement abstract method in derived class we have to use override keyword.
//The accessmodifiers and return types(like void,int etc) must be same in abstract method and
//in derived class method.
public override void pqr()
{
Console.WriteLine("Implementing abstract method");
}
}
public class zzz
{
public static void Main()
{
//We cannot create an instance to the abstract classes i.e we cannot create an objects
//for abstract classes
//i.e aaa abs=new aaa();this will split an error.
bbb abs = new bbb();
abs.pqr();
}
}
Interfaces Program
Here I am going to explain Interfaces in similar way we can get clear idea. And compare the commentline which I mentioned in the same places for Abstract class and Interfaces we can easily understand what are the differences and similarities between abstract class and Interfaces.
interface yyy
{
//For interface methods also there will be no body i.e. There is no implementation like abstract classes only.
// In Interfaces we cannot use any access modifiers.By default these methods are public.
// Note:-In interface all the methods are by default abstract methods only.
//We cannot declare variables and concrete methods in interfaces.
void method1();
void method2();
}
interface xxx
{
void method3();
}
//Here a class can inherit more than one class.Important:-Where we achieving multiple inheritance here.
class bbb : yyy, xxx
{
//we have to must and should call all the interface methods in the derived class.
//To implement interface methods in derived class no need of override keyword.
//The accessmodifiers and return types(like void,int etc) must be same in interface methods and in derived class methods.
public void method1()
{
System.Console.WriteLine("in yyy class method1");
}
public void method2()
{
System.Console.WriteLine("in yyy class method2");
}
public void method3()
{
System.Console.WriteLine("in xxx class method3");
}
}
class mClass
{
public static void Main()
{
//We cannot create an instance to the interfaces also like abstract classes i.e we cannot create an objects for Interfaces
//i.e yyy abs=new yyy();this will split an compile error.
bbb abc = new bbb();
abc.method1();
abc.method2();
abc.method3();
}
}
Summary
By running these two programs we can get clear idea on both abstract classes and interfaces.
Abstract Class:
The class which contains the common features of components of several classes, but cannot it be instantiated by itself. It represents an abstract concept for which there is no actual existing expression. For instance, "Vegetation" is an abstract class - there is no such real, real thing as generic vegetation. Instead, there are only instances of vegetation, such as mango tree and rose plant, which are types of vegetation, and share common characteristics, such as having leaves and stem in at least part of the lifecycle.
SO in software engineering, an abstract class is a class in a nominative type system which is declared by the programmer, and which has the property that it contains members which are also members of some declared subtype. In many object oriented programming languages, abstract classes are known as abstract base classes, interfaces, traits, mixins, flavors, or roles. Note that these names refer to different language constructs which are (or may be) used to implement abstract types.
We can also say that abstract class is : -- A class which is used only as an ancestor and is never instantiated.
In other word a concrete definition will say that
A type of class with pure virtual member functions and one or more methods that are declared but not implemented, that behaves as a base class but prohibits the instantiation of any members of that class. i.e. It has a complete interface but only a partial implementation It is used to take advantage of inheritance yet prohibiting the generation of objects that are not completely defined. Concrete subclasses of an abstract class are required to flesh out the implementation by overriding the abstract methods. | http://www.dotnetspider.com/resources/2866-Differences-between-Abstract-class-Interfaces.aspx | CC-MAIN-2017-47 | refinedweb | 880 | 55.95 |

Holy cow, I wrote a book!
The
Hiram M. Chittenden Locks
(more commonly known as the Ballard Locks)
are a common attraction in Seattle.
But if you pay a visit for the next week, you'll find that the
large set of locks will be empty.
And not just empty of boats.
Empty of water.
The chamber has been emptied of water for annual maintenance,
and if you stop by, you can take pictures of a big hole in the ground.
Here's a question from a customer:
I made some changes related to my shell extension [details omitted],
but the changes don't show up in the Explorer
window when I refresh it.
Any suggestions on how to solve this problem?
When we asked how they were refreshing the Explorer
window, we were expecting something like pressing F5
or calling SHChangeNotify with
SHCNE_UPDATEDIR,
or maybe calling IShellView::Refresh
or possibly even
calling WebBrowser.Refresh from script.
But we definitely didn't expect this response:
SHChangeNotify
SHCNE_UPDATEDIR
IShellView::Refresh
WebBrowser.Refresh
I'm invoking the
Process.Refresh()
method from the
System.Diagnostics
namespace.
System.Diagnostics
Just because a method is called
Refresh
doesn't mean that it refreshes what you want.
I think this is somebody who just
saw a method name,
perhaps
inspired by IntelliSense
and—
Boom! You have it!—assumed
it did what was needed without actually reading
the documentation to check.
But you don't even need to read the documentation to know that
Process.Refresh has no chance of working.
Refresh
Process.Refresh
Since it's a method on the Process class,
the method is applicable to all processes.
But certainly there is no generic way to tell a process to refresh.
This magical Refresh method would have to know how to
refresh Explorer windows,
Firefox web pages,
iTunes mp3 tags...
And what would it even mean to refresh, say, a Notepad window?
Does that mean to throw away all changes and reload the original document?
Process
How do you know that there is no generic way to tell a process to refresh?
Well, for one thing, a single process like Explorer can be viewing
multiple objects that can be refreshed; which one are you refreshing?
Second, when you write your own program, how do you implement refresh?
Do you respond to some standard system Refresh message?
Or do you just add a Refresh option to your program's main menu
and give it some arbitrary command ID?
If there's not even a standard way to refresh your program's window,
then how can there be a standard way to refresh all program windows?
In this specific case, the Process.Refresh method
refreshes the Process object's internal cache of process
properties.
It doesn't actually do anything to the process itself.
How could it?
It's like
thinking that the Matrix.Rotate method
rotates the entries in a matrix.
Matrix.Rotate
Epilogue
Actually, I'm scared by this customer's question for another reason:
The fact that they even mentioned Process.Refresh
suggests to me that they wrote their shell extension in managed
code, which we already know
is strongly disrecommended.
Yes,.
Last year, I sent some email to the people who run our
team's check-in validation tool asking how I could add a new
rule to the validation tests.
One of the members wrote back,
"You do it just like this guy," and sent me a reference to
another check-in that added a validation rule.
That other check-in was made by me.
But wait, it gets better.
That other check-in?
It added the very rule I was thinking about adding.
Consider a class with
a bunch of BOOL members:
BOOL
// no nitpicking over BOOL vs bool allowed
class Pear {
...
BOOL m_peeled;
BOOL m_sliced;
BOOL m_pitted;
BOOL m_rotten;
...
};
You might be tempted to convert the BOOL fields
into bitfields:
class Pear {
...
BOOL m_peeled:1;
BOOL m_sliced:1;
BOOL m_pitted:1;
BOOL m_rotten:1;
...
};
Since a BOOL is typedef'd as INT (which on
Windows platforms is a signed 32-bit integer),
this takes sixteen bytes and packs them into one.
That's a 93% savings!
Who could complain about that?
How much did that savings cost you, and how much did you save anyway?
Let's look at the cost of that savings.
Code that updated the plain BOOL
m_sliced member could do it by simply storing the result
into the member.
Since it was a normal field,
this could be accomplished directly:
m_sliced
mov [ebx+01Ch], eax ; m_sliced = sliced
On the other hand, when it's a bitfield, updating it becomes trickier:
add eax, eax ; shift "sliced" into the correct position
xor eax, [ebx+01Ch] ; merge "sliced" with other bits
and eax, 2
xor [ebx+01Ch], eax ; store the new bitfield
Exercise: Figure out how the above trick works.
Converting a BOOL to a single-bit field saved three bytes
of data but cost you eight bytes of code when the member is assigned
a non-constant value.
Similarly, extracting the value gets more expensive.
What used to be
push [ebx+01Ch] ; m_sliced
call _Something@4 ; Something(m_sliced);
becomes
mov ecx, [ebx+01Ch] ; load bitfield value
shl ecx, 30 ; put bit at top
sar ecx, 31 ; move down and sign extend
push ecx
call _Something@4 ; Something(m_sliced);
The bitfield version is bigger by nine bytes.
Let's sit down and do some arithmetic.
Suppose each of these bitfielded fields is accessed six times
in your code, three times for writing and three times for reading.
The cost in code growth is approximately 100 bytes.
It won't be exactly 102 bytes because the optimizer may be able
to take advantage of values already in registers for some operations,
and the additional instructions may have hidden costs in terms of
reduced register flexibility.
The actual difference may be more, it may be less, but for a
back-of-the-envelope calculation let's call it 100.
Meanwhile,
the memory savings was 15 byte per class.
Therefore, the breakeven point is seven.
If your program creates fewer than seven instances of this class,
then the code cost exceeds the data savings: Your memory optimization
was a memory de-optimization.
Even if you manage to come out ahead in the accounting ledger,
it may be a win of just a few hundred bytes.
That's an awful lot of extra hassle to save a few hundred bytes.
All somebody has to do is add an icon to a dialog box and your
savings will vanished.
When I see people making these sorts of
micro-optimizations,
sometimes I'll ask them,
"How many instances of this class does the program create?"
and sometimes the response will be,
"Oh, maybe a half dozen. Why do you ask?"
But wait, there's more.
Packing all these members into a bitfield has other costs.
You lose the ability to set a hardware write breakpoint on a specific bit,
since hardware breakpoints are done at the byte level (at a minimum).
You also lose atomicity:
An update to m_sliced will interfere with a simultaneous
update to m_peeled on another thread,
since the update process merges the two values and stores the result
non-atomically.
(Note that you also lose atomicity if you had used a byte-sized
bool instead of a 32-bit BOOL because some CPU
architectures such as the original Alpha AXP cannot access memory
in units smaller than a DWORD.)
m_peeled
bool
DWORD
These are just a few things to take into account when considering
whether you should change your fields to bitfields.
Sure, bitfields save data memory, but you have to balance it
against the cost in code size, debuggability, and reduced multithreading.
If your class is going to be instantiated only a few times
(and by "a few" I'm thinking less than a few thousand times),
then these costs most likely exceed the savings.

Steam.
Another script which is present in the debian package and which is called every time Steam starts, is “/usr/bin/steamdeps”. Originally this was a Python script which checks (using apt) if you have all required dependencies installed, and will attempt to download and install any missing packages… that was too unfriendly to my liking, so I changed that script’s content to only display a message on standard output (which means you won’t even see that text if you start steam from the desktop menu). If anyone comes up with a decent Slackware alternative for “steamdeps” I”ll consider adopting it.
Gameplay
I have only played two of the available Linux games a lot so far. The Linux Steam client allows you to play the Linux Beta of Team Fortress 2 for free (and of course TF2 will remain free even after the beta) but I found that I am no longer so fond of fast-action, multi-player shooter games playing against hordes of unknown people. I like to team up with people I know… perhaps my age shows 😉
Luckily Valve published a new Beta game last week: their very first game Half-Life is now available as a native Linux game in Steam, and if you already own Half-Life (not the Source version, but the original game) in Steam then you will get the Linux Beta of Half-Life added to your game inventory automatically! If you bought a CD of the game in the past (before Steam existed, like I did) then you can import its CD key into Steam and it will cost you nothing. Playing Half-Life brought back fond memories. I have been in Deathmatches with my son for hours this weekend (he is a Team Fortress 2 guy but was hooked to HL and its interesting choice of weapons immediately).
Half-Life is of course an old game which every modern computer should play effortlessly. TF2 is built around the Source engine and is newer, but still my PC’s have no issues with it. I remember that Half-Life had measurable level load times, but on my current quad-core desktop, the load times are merely fractions of a second.
Sound works, in all games so far. I verified that I could use my microphone in Steam (View > Settings > Voice) by explicitly selecting the ALSA device instead of PulsAudio, but I have not yet tried in-game if the voice functionality actually works (I don’t like it when other people talk during a deathmatch, so I hesitate using voice myself).
Caveat: For some people (as seen on Google+), sound stops working when Steam updates itself (which can happen everytime you connect the client to the Steam platform) or even segfaults on startup. A hint from Valve’s developers on their bugtracker, indicates that you could try running “steam” as follows (must be done on a commandline):
STEAM_RUNTIME=0 steam
PulseAudio
One of the dependencies of this steamclient is the pulseaudio library. Installing that is no problem of course, but it had an undesired (at least for me) side-effect: I also have Skype for Linux on my desktop and KDE will autostart it when I logon. For some reason (probably because of the desktop autostart files “/etc/xdg/autostart/pulseaudio.desktop” and “/etc/xdg/autostart/pulseaudio-kde.desktop” which are installed by the pulseaudio package), Skype will see the pulseaudio sound system and grab that instead of using the ALSA drivers. There is no way around that except stopping Skype, killing the pulseaudio processes which have been started by Skype, and then starting Skype again. You can of course delete the above two files, but I found out that the following change to “/etc/pulse/default.pa” will also give Skype back its sound. This change tells PulseAudio to use ALSA for its output:
# Following two lines explicitly enabled to make PulseAudio use ALSA - Eric Hameleers load-module module-alsa-sink device=dmix load-module module-alsa-source device=dsnoop # Commented-out because of two explicit load-module lines above - Eric Hameleers #### Automatically load driver modules depending on the hardware available #.ifexists module-udev-detect.so #load-module module-udev-detect #.else #### Use the static hardware detection module (for systems that lack udev/hal support) #load-module module-detect #.endif # End commented out - Eric Hameleers
If an application (like Skype) grabs the PulseAudio sound system, it will now be able to produce sound in your desktop.
Voice in Half-Life dedicated server games
I also saw on-screen messages about Half-Life not being able to use my microphone when I play Deathmatch on a HLDS – Half-Life Dedicated Server. The game tells me “Unable to initialize voice codec voice_miles. Voice disabled”. The miles codec is an old codec which is not very efficient, and Steam games switched to the speex codec which uses less bandwidth and apparently has better voice quality. The issue must be fixed on the server side
Add the following line to your “server.cfg” file:
sv_voicecodec voice_speex
Clients connecting to the server should now use the speex codec instead.
I setup a HLDS dedicated server on my Slackware LAN server / build box. That was not trivial at all, dammit! There’s lots of confusing information in Steam’s own knowledge base. Ten years ago I ran a half-life dedicated server on the Internet, but that was before the Steam era, and setting up a server was painless back then.
I have been playing Half-Life with my son on that server which is a lot of fun. I would like people to discover the joy of playing this old-skool game against their friends. So in one of my next blogs I will document how I have setup that server, so that you can repeat it.
Perhaps we will see a “Slackware” server appearing in the game tracker sometime!
Cheers, Eric

On slackware64, I found I didnt have to install pulseaudio, but only the multilib pack. The same goes for the other dependencies. So in all, I installed 8 multilib packs (flac,libogg,libvorbis,oxygen-gtk2, and pulseaudio,json-c.OpenAL, and speex) and the steam client starts fine. I have sound in tf2 and voice in tf2 and steam. I don’t know if 32 bit users adverse to pulseaudio could do something similar.

If you are using an interpreted langague like python or my favoirte Dialect( needs more respect ) then you have to be a little careful with it because these have a "soft stack" that can only get so deep. They have to keep track of how deep they are and where that have been, rather then just a beq and jmp on some register value, so they know what to do next.

Yeah, that sort of assertion bugs me. My own experience has been the exact opposite - attempting to understand large Python programs that have evolved over a number of years is damn near impossible. I know, I've tried. The terseness of the language and the absolute lack of explicit typing means you can't just open up a random function and understand what's going on. You often have to trace backwards through the code just to discover what it's attempting to do.
Typically Python programmers try and paper over this problem with tons of doc comments. Problem is that like any comment, they can get out of date, and often aren't useful anyway. If I had a dollar for every time I've seen:

Software developers are increasingly being targeted by malware. Recent incidents include Nobelium, Octopus Scanner, and ZINC. To reduce the risk of open-source library adoption in the face of such attacks, developers need a toolchain that assists them in evaluating untrusted content.
In Visual Studio 2022 we’ve been focused on developer and team productivity. Key to this is how the IDE can help developers evaluate the level of trust for code. Visual Studio Code recently introduced Workspace Trust, and today we’ll discuss how Visual Studio 2022 is also redesigning it’s trust settings functionality, starting in Visual Studio 2022 Preview 3.
The new Trust Settings functionality aims to raise awareness about the risks in handling unfamiliar code and helps protect against malicious actors, who are targeting scenarios ranging from opening content (e.g., repositories, solutions, projects and/or files) to building and running applications with Visual Studio.
While you will benefit from these security improvements out of the box, we’ve made it a priority to provide organizations with the tools to centrally manage the experience to their needs.
A trip down memory lane
To provide the feature rich experience of the Visual Studio IDE, a project system first needs to evaluate the contents you are about to open. This process – based on design-time builds – helps us identify the project structure and its dependencies, and is essential for many of the great features we offer such as code navigation and IntelliSense.
However, from a threat evaluation perspective, building code is equivalent to execution. This means that a malicious actor could create a scenario where simply opening content inside Visual Studio could become an attack vector to compromise you or your company.
Back in Visual Studio 2002, we introduced a content trust prompt. When you attempted to open a project from a location that was not previously trusted, the warning dialog would let you know and mention the implications of opening untrusted code.
In Visual Studio 2015, we extended the trust coverage to items outside the project scope and leveraged the “mark of the web” attribute, as a trust indicator for those items. While at the time it was a good decision, inconsistent usage of the “mark of the web” attribute, led to problems for designs that relied on it.
With the widespread adoption of open-source software, there’s been a shift in how most developers obtain and consume project samples. While this allowed us to create great new experiences, it also brought new security considerations.
With Visual Studio 2022, we want to help you safely browse and edit code no matter the source or author. To that end, we have overhauled our Trust Settings functionality and will provide an additional layer of security when trying to open content (e.g., solutions, projects, files, or folders) that wasn’t previously defined as trusted. Our new functionality consists of two main components: trusted locations & restricted mode.
Trusted locations
For Visual Studio 2022 Preview 3, you’ll have to manually enable the “trusted locations” feature. Once enabled, Visual Studio will detect if you are attempting to open untrusted content and will show a new dialog that warns you about the security implications:
After enabling the feature, all content opened inside Visual Studio 2022 is considered untrusted until you or your organization (via Group Policy) adds it to the list of “trusted locations”. You can trust a folder location, a git repository or a git repository owner directly from the trust dialog or the trust settings dialog:
/>
Security and usability are frequently at odds. Each developer views that tradeoff differently. For that reason, we are providing multiple workflow optimizations to reduce the amount of trust related prompts and thus help minimize unnecessary distractions to your workflow.
For example, when you open a repository, the trust dialog will allow you to trust at the repository or repository owner level. This means that if you fully trust the owner of the repository (e.g., a repository developed by a trusted colleague or your organization), you can choose that option and never be prompted again when opening repositories from that owner. As a benefit of the Visual Studio sign in experience, repository settings will roam with your account, helping streamline your experience regardless of where you use Visual Studio.
We are excited about these new capabilities and are putting the final touches towards enabling them by default in the next preview. In the meantime, you can enable them via Tools > Options > Trust Settings and checking the “Require a trust decision before opening content” option:
Restricted mode
Making a trust decision about source code is hard and frequently entails manual code inspection. To assist in this scenario, we are introducing a Visual Studio mode to browse and edit untrusted code.
While this mode won’t include features that require design time builds (e.g., code analyzers, visual designers, etc.), it will allow you to open and inspect untrusted code safely (e.g., without the risk of remote code execution), and help you make an informed decision towards trusting content and enabling the full Visual Studio experience.
While restricted mode is not yet available in Visual Studio 2022 previews, its coming very soon and we will share more information shortly.
Enterprise management
We’ve made it our priority to provide organizations with the means to centrally manage their experience via the Windows group policy functionality. For example, an organization could decide to limit Visual Studio usage to only a pre-approved list of trusted repositories, and disallow the ability to trust and open content outside of those boundaries.
This functionality is already available in Visual Studio 2022 Preview 3 and we’ll go over the details in a future blog post.
Wrapping up:
We are excited about these new features and can’t wait till they’re all available for you to try out!
Let us know what you think about the experience, what new features you would like to see supported and how we can further improve things to better fit your workflow! Send us your feedback via the Developer Community portal, or via the Help > Send Feedback feature inside Visual Studio.
You guys/girls have a beautiful Windows Sandbox. Why not running it inside instead of showing a dialog warning? Dialog warnings usually start to annoy users after a while. Or it breaks stuff and people click on “Yes I accept everything”. You can see this on the cookie banners on webpages or on the UAC dialog in Windows. And there is a reason why Windows Defender don’t prompt a dialog when it finds something untrustful.
The better attempt would be to just make it work and silently secure it from background. If it allows us to debug code and use everything in VS but all code is ran sandboxed then it has a very high chance to be effective.
Hi Max!
Thanks for the feedback! I agree with your assessment that running the full Visual Studio experience in a sandbox has a lot of advantages.
While I didn’t call it out in the post, we are actually exploring the possibility of running Visual Studio in some sandboxed/isolated environment. Having said that, we don’t have any timeframe or more information to share yet.
Happy coding!
It’s not just the source code that I wonder about. I love nuget and the ability to bring all this great functionality into my projects. I would like to run a quick check on what the binaries are accessing. Namely, seeing something that touches the IO namespace and includes calls to open a file raises a flag for me when it’s a tool or utility that really doesn’t have any business doing that. It’s not just looking at the gross dependencies. It can get as far down to individual classes and method calls. I don’t have the time to search every method call in a library.
I can’t remember the last time that I needed to read and write the registry. If I get a library that wants to make calls to these APIs, I’m suspicious. Especially when the library is something mundane, like parsing command line arguments. A tool that scans these DLLs for possible security issues would be useful. I see the problem with trying to define what I consider a security issue might be different than another person or organization.
Hi Martin!
Completely agree with your assessment!
While I don’t have many details to share yet, we have been discussing how to let users know if a NuGet package has vulnerabilities. While this might cover everything you are discussing, it’s just an example of some of the things we are considering for expanding and improving the space.
While these improvements are more than welcome, why is Visual Studio the only IDE than still has workloads that require running the whole IDE as Administrator?
I never had to run any UNIX based IDE or competition IDEs as such high level user unless debugging system services.
Hi Paulo & thanks for the feedback! While I don’t have context about why that decision was made, I encourage you to create a suggestion ticket with the specific workloads or features that are causing the behavior.
When working with IIS you are fast bound to Admin rights for some actions.
Then working with .NET Core or newer I was never forced to use Admin rights with few exceptions (e.g. registering a Windows Service requires Admin rights).
While I agree related security issues, I see literally nothing how VS can help here. Untrusted source? No code analysis? Umm… sounds not so impressive. Seems you started some “protection functionality”, having no idea WHAT you gonna achieve.
And theoretical question: FOR WHO you make this “protection”? Enterprise projects – barely they use “doubtful libraries”. Hobby projects – they don’t worth to worry about. Looks like you do “protection for sake of protection” – just to make busy all people you hire.
Better if you switch off any telemetry you embed in MY CODE. While telemetry inside VS code is your business, telemetry compiled into my C# program is total violation of security!! Stop it and don’t put nose in our code – this is security problem!
“Improving developer security with Visual Studio 2022” – almost 22yrs on and the MS VS team is doing everything but not protecting the intellectual property of the developer/company ever since DotNet ver 1.0 & VS2002.
Our application source code is not open source and there is no option to secure our app source code from decompiling. Using 3rd party tools to achieve this is expensive as well as it is not full proof.
Why not invest your valuable time, resource money, and efforts in securing sources code from decompiling. All I want is a simple project-level tick-mark option “Protech app from decompiling” and VS does the rest when the assembly is compiled to release mode.
I am still maintaining few legacy VB6 apps and they are much safer than complied DotNet apps. I want something rock-solid native to VS protection against decompilation or exploring source code inside my assembly.
Do you allow decompilation of WinOS & Office apps files? Ans is NO.

Adobe Reader XI Installation - Error:1642 - Kace 2000 3.6.98680
After updating our K2000 from 3.5 to 3.6 we found that our Adobe Reader XI fails to install as a post install task. The task fails and gives me the following -
Our file structure is as follows that is located in C:\KACE\Applications\39
The Batch file reads
msiexec.exe /I adberdr11000_en_us.msi TRANSFORMS=acroread.mst /passive
msiexec.exe /update AdbeRdrUpd11004.msp /passive
-------------------
The actual post installation task has the folder zipped up correctly and the command line just has AdobeReader.bat. We are not using the call or start instruction.
Any help would be appreciated
Answers
Hi Jason,
if you try directly a post install without bat
import just msi file and use cde line :
msiexec.exe /I adberdr11000_en_us.msi TRANSFORMS=acroread.mst /qn
work or not?
on your bat script if you try to add :
start /wait msiexec.exe /I adberdr11000_en_us.msi TRANSFORMS=acroread.mst /qn
start /wait msiexec.exe /update AdbeRdrUpd11004.msp /qn
i hope that can help you
msiexec /passive /i adberdr11000_en_us.msi TRANSFORMS=acroread.mst
msiexec /passive /update AdbeRdrUpd11004.msp
msiexec.exe /passive /i adberdr11000_en_us.msi TRANSFORMS=acroread.mst
msiexec.exe /passive /update AdbeRdrUpd11004.msp
Testing now and will see what happens.
According to the XML<Task ID="86">

1642 is telling you that the patch isn't correct for the installed product.
How you proceed depends on why WI thinks that that's the case. Does the patch get applied in a stand-alone test? If you remove the patch entry from the command ilfe, does that flavour of Reader get installed?
BTW, my rule of thumb for command files and script of any kind is: aways, always, always, always, ALWAYS use full paths for everything on the command line. Never EVER assume that the OS will find the file. | http://www.itninja.com/question/adobe-reader-xi-installation-error-1642-kace-2000-3-6-98680 | CC-MAIN-2017-39 | refinedweb | 346 | 53.07 |
Tabs
To show tabbed content within Markdown files, you can fall back on MDX. Docusaurus provides
<Tabs> components out-of-the-box.
And you will get the following:
- Apple
- Orange
- Banana
info
By default, tabs are rendered eagerly, but it is possible to load them lazily by passing the
lazy prop to the
Tabs component.
#Syncing tab choices
You may want choices of the same kind of tabs to sync with each other. For example, you might want to provide different instructions for users on Windows vs users on macOS, and you want to changing all OS-specific instructions tabs in one click. To achieve that, you can give all related tabs the same
groupId prop. Note that doing this will persist the choice in
localStorage and all
<Tab> instances with the same
groupId will update automatically when the value of one of them is changed. Note that
groupID are globally-namespaced.
- Windows
- macOS
- Windows
- macOS
For all tab groups that have the same
groupId, the possible values do not need to be the same. If one tab group with chooses an value that does not exist in another tab group with the same
groupId, the tab group with the missing value won't change its tab. You can see that from the following example. Try to select Linux, and the above tab groups doesn't change.
- Windows
- macOS
- Linux
Tab choices with different
groupIds will not interfere with each other:
- Windows
- macOS
- Windows
- Unix
#Customizing tabs
You might want to customize the appearance of certain set of tabs. To do that you can pass the string in
className prop and the specified CSS class will be added to the
Tabs component:
- Apple
- Orange
- Banana | http://deploy-preview-4756--docusaurus-2.netlify.app/docs/2.0.0-alpha.74/markdown-features/tabs | CC-MAIN-2022-05 | refinedweb | 285 | 68.2 |

Hello everyone,
I'm trying to make a script that renames a file. I'm using FileMove but I'm really confused.
The name change is on the EXTENSION, not on the file name itself. I need to change it from ".exe_" to "exe".
FileMove is returning a 0 value and the file is clearly not renamed. Here is the relevant code.
For $index = 1 to (UBound($file_array) - 1) $new_file_name = StringTrimRight($file_array[$index], 1) FileMove($dir & "\" & $file_array[$index], $dir & "\" & $new_file_name) Next some context notes:
$file_array!

Hi,
while debugging sometimes I need the au3 stripped script with /mo parameter, so that error lines in the error message match the script. Things I use often I put inside sendto folder (shell:sendto) so I can push my file to this with right click fast. A long time I had problems with some of my scripts stripping this way because the some paths to my script included spaces (you should not do that). But here’s my solution fixing that problem:
Local $sPathToAU3Stripper = "" ; fill in the path here Local $sPath If $CmdLineRaw = "" Then ; you didn't do it with sendto $sPath = FileOpenDialog("Which file you want to AU3-strip?", "","AU3 (*.au3)", 3) If @error Then MsgBox(0, 'Error FileOpenDialog:', @error) Exit EndIf Else $sPath = $CMDLINE[1] EndIf Local $sPath_quoted = '"' & $sPath & '"' ShellExecuteWait($sPathToAU3Stripper, $sPath_quoted & ' /mo', "", "", @SW_HIDE) I hope someone will find it useful.
Regards, Conrad

Kernel panic - not syncing: Fatal exception in interrupt
What is the linuxdvb module?
It's a module written by me. It run's stable for the last six year's. Since the
latest kernel upgrade i got this BUG. This error is hard to reproduce, but it
seems to trigger when a highmem address (allocated in userspace) is passed to
vmalloc_to_page.
The problem is almost certainly in the driver's vmap_to_dma_addr() function. If
you can reporduce without the driver loaded, reopen the bug...
Hi wise guy, maybe you are touched by god, but if you can read and learn then
take some time and read the function vmalloc_to_page. And if this won't help
then take a look here.
If you after that always think the macro BUG_ON() is a joke in highmem.c line
38, then you should change your job.
Good luck ....
To workaround the BUG inside the 'kmap_atomic_prot' function is to write your
own version of 'vmalloc_to_page'. The big point is to avoid the use of
'kmap_atomic_prot'. We don't need to reinvent the wheel. There is already a
similar function called 'lookup_address' in 'arch/i386/mm/pageattr.c'.
Unfortunately this function is not exported as SYMBOL. So we copy the code and
add two lines (see dvb_vmalloc_to_page) to have a working 'vmalloc_to_page'.
static pte_t *dvb_lookup_address(unsigned long address)
{
pgd_t *pgd = pgd_offset_k(address);
pud_t *pud;
pmd_t *pmd;
if (pgd_none(*pgd))
return NULL;
pud = pud_offset(pgd, address);
if (pud_none(*pud))
return NULL;
pmd = pmd_offset(pud, address);
if (pmd_none(*pmd))
return NULL;
if (pmd_large(*pmd))
return (pte_t *)pmd;
return pte_offset_kernel(pmd, address);
}
struct page* dvb_vmalloc_to_page(void * vmalloc_addr)
{
struct page *page = NULL;
pte_t *ppte, pte;
ppte = dvb_lookup_address((unsigned long)vmalloc_addr);
if (ppte != NULL)
{
pte = *ppte;
if (pte_present(pte))
page = pte_page(pte);

It was another fun day AjaxWorld. I had a good time during my talk Silverlight 2.
Silverlight is a cross-browser, cross-platform, cross-device. Plug-in for building and delivering the next generation of .NET based media experiences and rich interactive applications for the Web.
Silverlight does not require Windows, .NET or IIS on the server.
Silverlight 2 just shipped a few days ago, and already we have some great customers going live.
NBC Olympics -.
Notice the use of immediate seek to anywhere in the stream and adaptive streaming that gives you just the right bit-rate content for your connection.
Democratic National Convention - In August, the Democratic National Convention was streamed live using Silverlight, and broadcast a 2Mbit live video feed of the event and speeches - receiving outstanding feedback from audiences watching it.
This video was delivered live to millions of viewers all over the world at higher quality and bit rate than traditional TV. Now, all the content is available for viewing on demand.
Hard Rock - The folks at Hard Rock have the world's largest collection of Rock-and-roll memorial in the world. They hired the good folks at vertigo to build. Notice how the gigabytes of images are easy to zoom into and pan around. All streaming download of images...
Health Care Demonstrator - This is an example app that shows how to build a great line of business application with Silverlight.
Quake Game - Check out this very cool Quake game in Silverlight. Look at the frame rate... even in full screen!
Next I showed the latest progress on Moonlight with a Linux openSUSE 11.0 VPC (thanks Miguel!)
Next, I built a very simple Silverlight 2 application in Eclipse using the Eclipse Tools for Silverlight.
First we create a new Silverlight project in Eclipse.
Now, we just drag the button from the toolbox in Eclipse
Notice we get autocompletion in the source view in Eclipse
Then we can easily handle the click event in Eclipse
Then in code view, we get auto completion and error reporting in C# in Eclipse.
Next I built a simple Silverlight 2 application from scratch in the free VS2008...
For this demo, I only used freely available tools... In particular everything I show works in Visual Studio 2008 Web Developer Express and the Silverlight Tools for Visual Studio 2008.
Download the complete sample.
File, New Project
Next you can select what server side project to associated your Silverlight app with. Notice you can even have one dyamically generated for you. Also, notice you don't need .NET on the server, in fact you can deploy Silverlight from a Linux server.. all you need is http.
Notice the client and web project in the same solution and the Xaml view and the preview view.
Notice the great Xaml intellisense.
Now we get to write client side C# code... we can even do breakpoints, etc.
private void btn1_Click(object sender, RoutedEventArgs e) { btn1.Content = "Oach!"; }
Now, check out the server project, it includes ClientBin with a Silverlight.xap file that includes our clientside code... The cool thing is this is just a zip file... so you can see inside it easily.
Run it and check it out! works perfectly.
But this is Silverlight, let's see if we can make it a little more sexy. Let's open it up in Express Blend.
Notice Blend is built for Designers...
Let's make the design surface a little bigger then do some gradients
and finally a motion path..
The great thing is the project just refreshes in VS
Now we need to get some real data into this app.
First we add a datagrid (we put it and the button in a StackPanel)
<StackPanel> <Button x: <Button.RenderTransform> <TransformGroup> <ScaleTransform/> <SkewTransform/> <RotateTransform Angle="-49.157"/> <TranslateTransform/> </TransformGroup> </Button.RenderTransform> </Button> <data:DataGrid</data:DataGrid> <StackPanel>
Then we go to the server project and add some data.. In this case an Entity Framework data model. This let's us use LINQ to get access to the data rather than doing queries in code rather than in T-SQL.
Select the employees tables we need then, you get this view in the designer. Notice the Photo filed is too big to pass to the client, so we can just remove it here.
Now let's add a web service to pass this to data to the client. Let's add a Silverlight-enabled WCF service.
[ServiceContract(Namespace = "")] [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] public class NorthwindService { [OperationContract] public IEnumerable<Employee> GetEmployees(string nameContains) { var db = new NORTHWNDEntities(); var q = from emp in db.EmployeeSet where emp.FirstName.Contains(nameContains) orderby emp.LastName ascending select emp; return q.ToList(); } }
private void btn1_Click(object sender, RoutedEventArgs e) { var client = new ServiceReference1.NorthwindServiceClient(); client.GetEmployeesCompleted += new EventHandler<GetEmployeesCompletedEventArgs>(client_GetEmployeesCompleted); client.GetEmployeesAsync("b"); btn1.Content = "Oach!"; Storyboard1.Begin(); } void client_GetEmployeesCompleted(object sender, GetEmployeesCompletedEventArgs e) { datagrid1.ItemsSource = e.Result; }
Notice the column reordering, editable cells, sorting, etc.
Hope you enjoyed it! Here is the completed sample.

Methods are declared with the
fun keyword in Kotlin, whereas most other languages use
def (e. g. Scala, Python) some use
fn (e. g. Rust) or
function (JavaScript). I wonder whether it was intended or at least a welcome sideeffect to have the word “fun” in the language
Was it?
Why `fun`?
Methods are declared with the
It took me a while to get used to
fun, and I would have preferred the straight-forward
function. (If
override and
companion object aren’t considered too long,
function shouldn’t either, even though it’s used more often.) One nice aspect (if you will) is that
fun,
val, and
var all have the same length, but I don’t know if that played a role in the decision.
PS: JavaScript uses
function.
I don’t think there’s any word for defining functions that “most” languages use. We use “fun” because we like it - and yes, we do know what the word means in English.
I think there is some masterful psychological manipulation going on here. Every time you write a function in Kotlin they want you to believe you’re having fun.
I mean, think about it… all the awesome stuff they’ve done with the language; it’s like they want you to enjoy yourself while programming. Having fun while programming, absurd. | https://discuss.kotlinlang.org/t/why-fun/1396 | CC-MAIN-2018-30 | refinedweb | 223 | 81.43 |

Packed project
Week ago I begin to learn Gdk, Cairo, Pango, Glade. I have discribed wonderfull world of GUI in linux environment. "Great!" - said I for myself.
I Create two similar projects GTK#: first of them is with using Cairo; second of them is without Cairo.
Both of them draw some animation on drawingArea.
I set doubleBuffered = true in both projects;
So first project works without problem but because of using atlas (cutting, coping, zooming parts of atlas) it is easy to use second project.
After start debuging of second project application draw animation but 1-5 minutes later image inside of drawingArea stops (freeze). When I minimize and than maximize application window I get gray canvas with blue title on top. Console output does write me anything.
This is code

You can have indents, sizes, fonts, etc etc. In this example Pango.Layout, the width is set by converting the window width into pango units because layouts are not measured in pixels. The wrap goes hand in hand with width so that any long text will wrap at the set width value. The FontDescription is quite handy. Here you can define your font. Thanks go to TD on the #mono channel for his tips here. If you want to know the names of available fonts you can enter here, go to gedit and look at the available font names.

Hm, I'm sorry but first project with cairo has this problem too. But troubles has come later more time than in second project | https://bugzilla.xamarin.com/40/40467/bug.html | CC-MAIN-2021-39 | refinedweb | 584 | 61.63 |
101611/how-do-i-convert-from-int-to-string
I'm working on a project where all conversions from int to String are done like this:
int i = 5;
String strI = "" + i;
I'm not familiar with Java.
Is this usual practice or is something wrong, as I suppose?
Normal ways would be Integer.toString(i) or String.valueOf(i).
The concatenation will work, but it is unconventional and could be a bad smell as it suggests the author doesn't know about the two methods above (what else might they not know?).
Java has special support for the + operator when used with strings (see the documentation) which translates the code you posted into:
StringBuilder sb = new StringBuilder();
sb.append("");
sb.append(i);
String strI = sb.toString();
at compile-time. It's slightly less efficient (sb.append() ends up calling Integer.getChars(), which is what Integer.toString() would've done anyway), but it works.
To answer Grodriguez's comment: ** No, the compiler doesn't optimise out the empty string in this case - look:
simon@lucifer:~$ cat TestClass.java
public class TestClass {
public static void main(String[] args) {
int i = 5;
String strI = "" + i;
}
}
simon@lucifer:~$ javac TestClass.java && javap -c TestClass
Compiled from "TestClass.java"
public class TestClass extends java.lang.Object{
public TestClass();
Code:
0: aload_0
1: invokespecial #1; //Method java/lang/Object."<init>":()V
4: return
public static void main(java.lang.String[]);
Code:
0: iconst_5
1: istore_1
Initialise the StringBuilder:
2: new #2; //class java/lang/StringBuilder
5: dup
6: invokespecial #3; //Method java/lang/StringBuilder."<init>":()V
Append the empty string:
9: ldc #4; //String
11: invokevirtual #5; //Method java/lang/StringBuilder.append:
(Ljava/lang/String;)Ljava/lang/StringBuilder;
Append the integer:
14: iload_1
15: invokevirtual #6; //Method java/lang/StringBuilder.append:
(I)Ljava/lang/StringBuilder;
Extract the final string:
18: invokevirtual #7; //Method java/lang/StringBuilder.toString:
()Ljava/lang/String;
21: astore_2
22: return
}
There are a proposal and ongoing work to change this behavior, targetted for JDK 9
Use the lines of code mentioned below:-
String ...READ MORE
You can also use Java Standard Library ...READ MORE
If you're looking for an alternative that ...READ MORE
In Java 8 or later:
String listString = ...READ MORE
Here are two ways illustrating this:
Integer x ...READ MORE
String fooString1 = new String("foo");
String fooString2 = ...READ MORE
You can achieve that concisely in Java:
Random ...READ MORE
String s="yourstring";
boolean flag = true;

Introduction: Android Native Language Speaking Clock
My eyesight is not very good, It is the reason I wrote this script, I am not a programmer, I just want an application that can help me determine the right time, especially when I woke up in the middle of the night, of course I want to know what time it is. Very difficult if I had to look for glasses, then turn on the light only to look at the clock, while the Android smartphone can be reached without having to get out of bed.
The first thought is a watch that speaks, because with the ability from Google Text-to-speech, of course is easier and more pleasant to hear the designated time using language commonly used in everyday life.
Step 1: Change Your Google Text-to-speech Language
So the first step is to choose the language to be used, then install voice data, I use the Bahasa Indonesia, you can choose any language as you like.
Step 2: Install Python
Download and install Python to your PC, from , i prefer version 2.7.10. Let's we try a bit of Python, it's just an easy script :
In Python Shell type like this :
- import time (enter)
- clock = time.strftime("%I:%M") (enter)
- print clock (enter)
- result is current time, only hour and minute (that's all we want)
If there is no error then you're succesfull installing Python in your PC, we're not compile the script into an APK, we just test the script. Now we need to save that script.
in Python Shell type like this, create a new file (Ctrl+N), type as follow :
import time
clock = time.strftime("%I:%M")
print clock
and save it as you like, and you can run it, to see the result. For full documentaion about strftime you can read it at
Step 3: Adding SL4A to Your Android
Yes, we use SL4A for interprete our script, you can download it from , now you can copy your previous script to your android, you can use Dropbox or PCSync from File Manager, save to your desire places (the place may vary, depends where you're install SL4A app.).
Open your script and adding few line; modify line 1 and 6, add lines 2, 3, 4, and 7 as follow :
- import time, random, android
- droid = android.Android()
- greet = ['Hello ','Hi ','Hola '] # or anything you desire, with your own language.
- G = random.choice(greet) # this G variable will get random greet, add more variation is great!
- clock = time.strftime('%I:%M')
- print G+clock # you can remove this line if you like
- droid.ttsSpeak(G+clock)
and then save and run, you can remove line 6 if you like or add # in the begining of the line 6.
Now you can create a shortcut from your script to the main screen, or you can create a shortcut on the Lock Screen (for systems that support).
Step 4: Make Icon Bigger
You can using Dekstop VisualiseRto make bigger custom icon, if you prefer my icon file you can download and use it.
I know this simple script is far from perfect, you can develop this script to becomes more perfect and much better, by studying SL4A and Python further, you can create a script that tells you about the status of the batteries, show your location or perhaps make a personal assistant, or whatever it is.
Recommendations
We have a be nice policy.
Please be positive and constructive.
This is great! Thanks for sharing and welcome to the community! | http://www.instructables.com/id/Android-Native-Language-Speaking-Clock/ | CC-MAIN-2018-13 | refinedweb | 597 | 71.78 |
MyFaces Core 1.1 API Project
This API submodule implements all of the classes that are defined in the specification. If you are looking for API documentation about the classes that your JSF application needs to use, then see the javadoc for this module.
All the classes in this project are in the javax.faces namespace. In addition, it is forbidden for this module to provide a single public or protected class, method or constant that is not in the JSF specification; this ensures that user code compiled against one implementation of the specification will always be binary-compatible with other implementations of the specification. | http://myfaces.apache.org/core11/myfaces-api/ | CC-MAIN-2013-48 | refinedweb | 105 | 50.77 |
Hi,
Reviewing a linkage problem with a static data member of my class (problem on AIX), I started to doubt on its linkage type.
# Internal linkage : identifiers can only be seen within a translation unit.
# External linkage : identifiers can be seen (and referred to) in other translation units.
If the identifier for a class has external linkage, then, in the implementation of that class, the identifiers for the following will also have external linkage:
* A member function.
* A static data member.
()
A named class has external linkage, of that I'm sure. The static data member in that class has therefore also external linkage, hasn't it?
The standard says the following:
ISO/IEC 14882:2003(E)
9 Classes
9.4.2 Static data members
6 Static data members of a class in namespace scope have external linkage (3.5). A local class shall not
have static data members.
But what exactly is meant by the specification "in namespace scope"? Should a class with a static data member always be defined in a named namespace? That would seem strange to me...
Thanks! | http://cboard.cprogramming.com/cplusplus-programming/105697-internal-external-linkage.html | CC-MAIN-2013-48 | refinedweb | 182 | 66.33 |

SHANGHAI (ICIS news)--Rhodia expects China’s demand for polyamide to grow by 20% this year and very strongly in the longer term on the back of a robust automobile market, a senior executive from the French producer said on Monday.
"?xml:namespace>
“You can see it has a large automobile market, and many people have cars now. The 20% growth prospect is good, and it will also remain very strong in the longer term."
Edmund Yap, vice president of Rhodia’s Asia Pacific polyamide operations, said: "There is a strong automobile market -
By 2015, Asia would become the largest nylon 6,6 market in the world, accounting for more than half of the global market share,
In order to support the growth in Asia, Rhodia planned to expand its Asia polyamide capacity by 40-60% in the next few years, Laganier said.
Polyamide is a type of engineering plastic widely used in the chemical, automobile and machinery sectors.
Chinaplas is projected to draw 75,000 visitors from 130 countries.
The event runs on 19-22 April in Shanghai.

Far less useful than what you might imagine:

Well, nothing to stop you from writing a 'YASL' schema finder app and
putting it on the web (or using DNS or some other lookup mechanism).
For instance,
would work just wonderfully. In short, you don't want to add
distribution semantics into the mix, a unique identifier is
all that is required.

BUSTERTHOMPSON Staff writerRoger B. Proffer Sr. has never been one to stay in one place. At the ages of 14 and 16 in his hometown of Rankin, Michigan, Proffer ran away from his family farm for reasons he has yet to divulge. Starting in 1960 he served in the Air Force as an electronics technician, repairing aircraft radios and radar towers in East Asia and Vietnam until 1964. While working on a 40-foot tower in 1973 in Michigan, Proffer felt sharp pains in his chest. He was later diagnosed with lung cancer from working on open radar equipment and given about six months to live.

Become our fan @ facebook.com/citruscountychronicle and leave your comment on our Question of the Week post. Last week there was a national news story about Citrus County having one of the oldest populations in the nation. Thats no surprise. Todays question for those under age 40 and living in Citrus County: Why? What keeps you here? Question of the Week Dennis Grundy What keeps young people here is our families are here, younger people enjoy all the water areas Citrus has. What is needed are more job and career opportunities. There really is no type of industry based in Citrus. Citrus needs to attract businesses to start or expand their companies here. Because there are not many jobs or jobs that pay well for that matter younger people will go elsewhere to start their families. Veronica Davis I love Citrus County for the nature. It is essential that our environment here be preserved, but if we want more young people to stay, career and entertainment opportunities must be more widely available. No one wants to feel stuck somewhere, and that is what I hear from others my age. Ellen Howes My husband grew up here and always said when he had kids he would move back here. I couldnt be happier! So many fun family oriented things to do! We are currently expecting baby number two and Im sure she is going to love it just as much as her brother! Mandi Nicole Roxey I was moved here a few weeks after my 16th birthday, right in between my sophomore year. I cant say I was pleased, especially coming from St.Pete, which is significantly larger and has a lot more to do. But now that Im a parent I enjoy being here, and raising my son here. Cindy Green-Canfield Lack of money to get out keeps us here. There are no decent paying jobs here in Citrus County. ... We need jobs and entertainment to keep and attract young people. Lisa Martinec DeGraff My husband and I moved here eight years ago and we love it! So much nature to appreciate and we like the quiet, small town feel. If Citrus became too built up we would probably leave, thats why we left Pasco. Jennifer Reid I have lived here since I was 13 years old. Im now 28 and I can tell you the reason we tried to leave is because there is nothing for young people especially teens to do. The only option is either to get into trouble like drugs or to get pregnant. I was so fed up I moved away but due the bad economy I lost my job and had to move back with family. It upsets me so much that this community doesnt embrace youth. I honestly can not wait to try and move again because even at 28 theres nothing to do but drive over an hour to a decent beach or spring. Board to consider garbage out, in MIKEWRIGHT Staff writerGarbage coming in, garbage going out. Both have their place at Tuesdays county commission meeting. County staff will recommend allowing FDS Disposal Inc. to haul garbage from the town of Inglis to the Citrus County landfill for $40 a ton. Commissioners also will decide whether Citrus County School District garbage can be hauled to a private landfill in Sumter County, co-owned by Commissioner Scott Adams. FDS told county officials it plans to bid on the curbside pickup contract in Inglis, just across the county line in Levy County. Citrus ordinances allow the county to approve transfer of garbage from out of county to the Citrus landfill, at a deposit price that is approved by the county commission. FDS estimated it will deposit about 340tons a year of garbage in the Citrus landfill. At $40 a ton, that would net the landfill $13,600.

Board members conduct a workshop concerning over-the-counter medications shortly after 9a.m. Tuesday, after an administrative meeting and special meeting. Over the summer, Citrus County School District officials learned they would have to require students to bring a signed doctors authorization for all over-the-counter medications including lip balm, cough drops and sunscreen before it could be administrated. The Citrus County Health Department rescinded protocols used in the school clinics to treat students, as the doctor in charge felt they were too broad and legally didnt feel like he could sign protocols for every student in the district.

Plane crashes in local field BUSTERTHOMPSON Staff writerTwo men flying back home to Indiana from Lakeland, Florida, had to make an emergency landing Sunday afternoon in a Homosassa field when their plane malfunctioned. No injuries were reported. Citrus County Sheriffs Office responders were dispatched a little after 12 p.m. Sunday to a field off of West Country Club Drive in Homosassa when reports arrived of a downed plane. According to sheriff spokeswoman Lindsay Blair, the men requested an emergency landing at Crystal River airport when their single-engine Grumman American Cheetah plane suffered an unknown malfunction en route to Indiana from Lakeland. Due to the extent of the malfunction, the pilot had to make an impromptu landing in a field south of the airport in Homosassa. The plane avoided a house and several palm trees before clipping a power line, causing the plane to hit the ground, according to Blair. The pilot and his copilot denied medical assistance from Citrus County Sheriffs Office responders. The FAA is investigating the crash.

Adams believes the proposed tipping fee is too low. In an email exchange with acting public works director Larry Brock, Adams said the fee doesnt cover the actual cost of operating the landfill, which is $63 a ton. Brock responded that the $63 cost covers all landfill operations, including recycling and disposal of hazardous wastes. He said the cost of disposal alone which is the only request FDS proposes is $34 a ton. He also told Adams that the ordinance doesnt allow the county to charge less than the actual cost of disposal. Brock also said the county commission can accept the staff recommendation, reject it or set a different fee. Also Tuesday, the board will take up a request from Good Fellas RollOff Waste Disposal to transport school district garbage to the Heart of Florida landfill in Lake Panasoffkee. Adams, state Sen. Charlie Dean and Deans son, Charlie Dean Jr., are all co-owners of the landfill and garbage hauler. Good Fellas received a bid from the school board contingent upon county approval. The county ordinance requires commission approval to transport garbage out of Citrus County. Dean Jr. planned to seek that approval in June, but delayed it after company attorney David Dee said state law prohibits the county from restricting the flow of garbage across county lines. An agenda memo from Acting County Administrator Jeff Rogers doesnt address Dees opinion, though his letter is included in the backup. Rogers, instead, said the county commission must decide whether hauling the school garbage out of county would have an adverse financial impact on the landfill. When the matter was on the June agenda, Adams said he would abstain from any discussion and vote.Contact Chronicle reporter Mike Wright at 352-563-3228 or mwright@chronicleonline.com. a protocol for over-thecounter medications; however, after receiving legal advice from counsel, he rescinded his word. Upon investigation, school officials found that Florida School Health Administrative Guidelines, which the district follows, recommend treating over-the-counter medication the same as prescription medication, which requires a signature of authorization from a doctor. These guidelines did not sit too well with parents, and school board members said in August that they heard parents concerns and would search for a solution. Tuesday they will bring the topic back up for discussion in hopes of finding a resolution that both fits state guidelines and parents desire for convenience. Other items up for discussion: Expulsions and suspensions. State of the District, PartII. 2002 and served as secretary, president, foundation and international chairs. Proffer was also district governor for Rotary District 6950 from 2013 to 2014. Hes been progressively writing his story on, and the Chroniclemet with Roger Proffer to discuss his roles in the U.S. and abroad:CHRONICLE: So youre not a Citrus County native? PROFFER: No, born in Rankin, Michigan (in 1941), first time I left there I was 14 years old called a runaway. CHRONICLE: Why did you run away? PROFFER: That part of the story I havent written yet. CHRONICLE: So you were 14 when you left Michigan? PROFFER: The first time. Now, I got caught probably a year later, sent back and when I was 16 I left the second time. CHRONICLE: When you moved to Texas to start missionary work in Mexico, how was that? PROFFER: It was awesome; we worked with a couple different groups down there. We had some success and some failures just like anything else. CHRONICLE: What brought you to Florida? PROFFER: Lindas dad was from Florida, actually Tarpon Springs, so he came and visited us in Michigan and told us what Floridas like so we came along and visited and here we are. CHRONICLE: So, what did you end up doing when you moved to Tarpon Springs? PROFFER: We stayed in Tarpon for a short period, moved to Brandon and started an insurance company. I hated every minute of it. CHRONICLE: Why a military outlet store? PROFFER: We had an opportunity to buy out the GI surplus at Brandon, we negotiated and negotiated, but he kept changing the price so we said, the heck with it, and started new up here. CHRONICLE: And thats what led you to Citrus County? PROFFER: Right. Well, back 30years ago, you can buy surplus 10cents on the dollar; you buy $200 and turn into $1,000, $1,500 worth of surplus or more and there was a lot of money in it. CHRONICLE: You were on the Crystal River City Council from 2002 to 2006. What were your motivations for that? PROFFER: Well, we had a tremendous fight in this town. We had councilmen throwing chairs at each other; we were the laughingstock of the community. ... So I put my name in to calm things down along with (then mayor) Ron Kitchen. CHRONICLE: What were some of your polices? PROFFER: Well, the biggest thing was to get Crystal River moving in a positive direction again, which I believed we did in that period of time and the subsequent time behind that. CHRONICLE: What was that right direction? PROFFER: Same thing that happened in Inverness. Inverness has been on a positive direction for a long time with rebuilding the community and rebuilding the downtown section. CHRONICLE: How did you get involved in the Kings Bay Rotary Club? PROFFER: (Bob Boleware) invited me; actually I had two people invite me. CHRONICLE: How was your experience leading up to district governor? PROFFER: Its been awesome; Ive been involved in the community probably this last year because of my stint with Rotary International. I have just dropped out of sight as far as the community because you just dont have time; you have 48 clubs to watch over. CHRONICLE: What gave you that incentive to make the next step to district governor? PROFFER: They kept asking me to. Several people at Rotary International at our district level kept asking me because Ive been doing water projects in Honduras. CHRONICLE: So youve done international work? PROFFER: Mexico, Honduras and Guatemala, but our main focus since the no-name storm has been Honduras. CHRONICLE: How was it working in another country? PROFFER: I love it because the people are tremendous to work with because we dont do handouts, we do hand-ups and this is the key to success in a foreign country; you find out what they want and go in and help them do it. This is what we did and Ive done it for 20 years before I joined Rotary. CHRONICLE: Whats really next for you, what are some of your goals now? PROFFER: Well, my immediate goal is that I have two houses in Michigan Im working on, so Ive been tripping back and forth to there to finish them up and sell them. CHRONICLE: What about long-term goals? PROFFER: I really havent set a goal other than continuing mission work and water projects. ... Local here, I dont know yet. Theres a lot of different areas of need and Ill be working through the Rotary Club and figure out which area of need we need to be addressing. CHRONICLE: Youve had a lot of experience, how do you see that as a benefit wherever you go? PROFFER: The biggest thing is teaching people to be self-sufficient, no matter if Im in Honduras, Crystal River or Citrus County. Integrity is a big thing that I stress when Im talking with people. CHRONICLE: Best member of a community. PROFFER: Were working toward that, but there are many avenues to go yet and I dont know which way. I got to tell most people I still dont know what I want to be when I grow up. Contact Chronicle reporter Buster Thompson at bthompson@chronicle online.com or 352-564-2916.

The Daytona Beach News-Journal reported the deputies were at a towing service on an unrelated call Saturday when they heard an argument outside. According to the sheriffs office, one of the deputies went to investigate the argument and encountered an armed man. The sheriffs office is not yet releasing details about the exact sequence of events that led the deputy to shoot and kill the 52-year-old man. A spokesman for the sheriffs office said the officer perceived a threat and fired his duty weapon, shooting and killing the man.Event celebrates electric carsSARASOTA Dozens of electric car owners and enthusiasts marked National Drive Electric Week with a celebration in Sarasota. The Bradenton Herald reported that about 50 electriccar owners gathered Saturday at the Mote Marina Laboratory and Aquarium. The cars ranged from Teslas to Cadillacs and Chevrolet Volts. Chris Isaak organized the event. Isaak is an environmental engineer and author of the book, The Electric Car Revolution. Isaak said he did the first oil change in his electric car at 50,000 miles and that electric cars require less maintenance than traditional, gas-powered vehicles. The event was sponsored in part by Florida Power & Light. From wire reports

OPINION Page A10MONDAY, SEPTEMBER 22, 2014 Fooled againWith it all, I considered Obama a smarter and nicer guy than Bush. The hard evidence, however regardless of dancing up onto the stage and the pompous raised finger appears to the contrary. Now it seems we will war again a hemisphere and two seas from our shores to slaughter Muslims fighting Muslims, and heaven forbid the mention of oil. Our 21st century leadership having monstrously failed humanity, perhaps its time for the churches to consider releasing their Prince of Peace from their stony fortresses and finally allow Him a voice in the arena. There is a voice there isnt there or is humanity fooled again?Rafe Pilgrim Crystal RiverKind, caring manThe comments in the Sept. 12 Chronicleabout Mr. Batchelor were right he was a gentleman caring and concerned for the community a friend of Citrus County. I hope to attend the service for him if there is one open to the public. He was always willing to help with only my making a mere call, even by just being a friend (his wife was always helpful, too). The article did not mention that Mr. Batchelor voted as commissioner, along with Commissioners Josh Wooten and Gary Bartell, in a unanimous vote for the Citrus County Board of County Commissioners to sue the city of Crystal River for their invalid 2004 annexation that was won at the Inverness Courthouse by that Citrus County BOCC and commercial property owners as being ruled invalid a victory for the citizens and a historical decision. May Roger Batchelor rest in peace! Renee ChristopherMcPheeters Homosassa WASHINGTONT generally confident that their constituents need to be improved by spending the constituents money. The supposed problem for which the pay the voters idea purports to be a solution is this: Few Los Angeles residents are voting. Especially alarming to those who choose to be alarmed is the fact that only 23.3 percent of those eligible to vote did so in last years mayoral election. Well. Since the days of Hiram Johnson (1866-1945), who was governor 100 years ago, progressivism has intermittently made California an incubator of dubious ideas. One of which is that government should finetune political partisanship disagreements about how government should behave. If this looks like a conflict of interest, you have not embraced progressivisms, which is favored by people whose moral micrometers can measure such finetuning. Obviously, some level of financial enticement would draw to the polls a significant number of those who hitherto have not been moved by normal political exhortations or moral shaming. (Men left bloody footprints in the snow at Valley Forge in order to secure your right to select the candidate you prefer from a pair of progressives.) Whether the city, in its parlous financial condition, can afford this expenditure is a decision to be made, alas, by the political class that got the city into its condition. But when making the cost-benefit calculation, that class should ask: What benefit might result? Wills email address is georgewill@washpost.com. The apathy of the modern voter is the confusion of the modern reformer.Learned Hand, speech, Washington, D.C., March 8, 1932 Cashing in on voting NEW STRATEGY Government and business must work together The countys economic development council (EDC) has voted to adopt a new strategy moving away from government funding and leadership in the organization. The EDC, which solicits new industry to relocate or expand in the county and create employment opportunities, will now become a private organization. In doing so, the EDC will turn away from the use of government funds to supports its efforts. Currently, an annual tax on each business in the county is used to provide funding to the EDC effort. Going forward, the EDC will raise its own funds and operate as a private organization. The new direction is part of a reorganization that began in January, and after the August election results the plan is looking right on target. It appears that at least two members of the new commission will be opposed to using tax dollars to support economic growth at least through the EDC. In theory, it makes sense that the EDC operates privately and uses its own funds. But past efforts have proven unsuccessful because there just are not that many large businesses in the community that appear willing to pump dollars into such an effort. While Citrus County is predominantly a retirement community, it would be negligent to think a community does not need an industrial or manufacturing base. New industry pays taxes and offers employment opportunities. At the same time, industry does not make huge demands for services from local government. Without industrial growth, the tax burden will shift to our retirees and working families and we all saw how popular that was in the 2014 elections. When Duke shut down the nuclear plant, the county commission voted to shift some of that tax burden onto homeowners and a major revolt ensued. Government and retirees both need industrial expansion to take place. We hope that while county funding may stop, the commission will still understand the importance of being a strong partner with the reorganized EDC. There is intense national competition for industrial enterprises and Citrus County will be at a disadvantage if county government doesnt participate. The governments role is making sure that the permitting process is easy and that infrastructure needs such as water, sewer and transportation are available at a desirable location. The lack of progress at the Inverness Airport business park is a good example of government not getting the job done. The airport site is still not ready for business, even though leaders have been talking about this for a decade. Citrus County has not yet found an economic development model where everyone is comfortable with funding or strategies. And maybe the lesson is that its impossible to make everyone happy. But we do know that if government and business leaders are not working together for job growth and industrial expansion there is zero chance that it will happen. THE ISSUE:A new model for EDC.OUR OPINION:Private effort may work, but government still must be at the Looking for sand sculptorIm just calling to tell whoever did the sand sculptures at Fort Gulf Island Trail last evening, which would be (Sept. 12), I went out to take a picture of the sunset and found the two most beautiful sandsculpted dolphins Ive ever seen with initials LMA on it, and I couldnt make the other ones out.

Now how does she know the person stole that wallet? He might have found it after somebody took the money and threw the wallet away. She ought to find out whether he stole it or not before she talks him down and says hes a thief. She ought to be thanking the person that found it and mailed it to her. There two sides to that story. Before you condemn somebody, find out if theyre guilty.

Below-normal precipitation and normal or abovenormal temperatures are forecast in the week ahead, according to the National Weather Service, and experts said the three-year drought isnt likely to be relieved in October, November and December.

Last January, extreme drought covered 23percent of the state, with only 5percent considered to be in the most extreme category of exceptional drought. Half of Utah was reporting moderate drought and 16percent severe drought.

PETERSBURG The didnt get things rolling our way, Tampa Bay manager Joe Maddon said. Its just one of those years here. Its really hard for me to pinpoint. Their 81st loss assured the Rays of a non-winning season for the first time since 2007.

SEANARNOLD CorrespondentINVERNESS With his son Randy in tow, the inimitable Wayne Anderson notched his third Super Late Model win of the season in Inverness, and James Peanut Johnston overcame a late caution in snatching his first Pure Stock win in three years at the Citrus County Speedway on Saturday. In other racing action, Kevin Stone came from behind to prevail in a thrilling Mini Stocks feature, and Mike Belsuar, of Punta Gorda, scored his third feature win of the year at Citrus in Three-Quarter Midget Sprints. Anderson got by Randy and his other son, Ricky, in the opening lap to settle in behind then-leader Dave Pletcher for the early going. On lap 10, Anderson slid to the inside of Pletcher, putting the pair side-byside for a lap, before seizing the lead for the 25-lap victory. Randy Anderson took second, and a hard-charging Scott Grossenbacher steadily closed the gap on the former over the waning laps in taking third. We had a really good car, Grossenbacher said, but the guys just made it hard for me to get up there. I would have liked to have another 25 laps, but those guys were probably out there cruising toward the end. Randy Anderson, whos finished in the top 3 in all six of his races at Citrus this year, now leads his father by just four points in the standings. As long as the points stay in the family, its nice to have, the young Wildwood driver said in victory lane. Were extremely happy with this finish. Johnston put an exclamation point on what has been his most successful stretch in a racecar at Citrus. The Brooksville driver had the lead from lap 5, and later started to pull away from the field until a crash on the second turn of lap 22, involving Larry Welter Sr., James Holly, Happy Florian and Mike Gilkerson, drew a yellow and a double-row restart. With Chuckie Smith on his outside on the pole, Johnston re-established his advantage and fended off Smith for the remaining three laps.

Keselowski led 78 laps, hit the wall, and still was in the hunt for a win. He failed in his bid to win a third straight Cup race, though he salvaged a seventhplace. Its not all about winning and losing at this point. Its about advancing, said Harvick, who led a race-high 104 laps. Denny Hamlin, Greg Biffle, Kurt Busch and Almirola are in the bottom four of the 16-driver field at and risk of getting cut at Dover.lins No. 11 Toyota suffered from fuel woes and was later collected in a multicar wreck and will likely need a win at Dover to advance. Its going to be hard to do it without some help, Hamlin said.

It was Johnstons sixth-straight night with a top-3 finish. He also collected his first heat win of the year. Three years, it took me to get this one, Johnston said from victory lane. So Im happy. Smith won his sixth heat in seven weeks. Weve come a long way this year, Smith said. Im happy with the car for sure. Mark Patterson held at least a share of the lead in Minis from the green flag to lap 23, when Stone, the 2013 points champion, overtook him from the inside on the first and second turns. Jesse Mallory pulled even with Jason Terry in the second position on 13, before the two wrecked out of the fourth turn. Travis Hoeffler, whos made a significant impact on the class since making his 2014 debut on Aug. 16, moved in behind Patterson out of the restart. After Stone eclipsed Hoeffler on lap 20, Hoeffler followed the Dade City driver by Patterson to claim second place. Mallory was penalized for putting Patterson, who finished third, into a slide coming out of a restart on 17. That was a great race, Stone said. Mini Stocks are the best class out here as far as finishes go. These guys race really hard, and they race really clean no complaints. Though Belsuar owned the lead by the sixth lap of the Midgets feature, he continued to face heat from early-leader Steven Maier for most of the 25-lapper. The pair rubbed up on the fourth turn of 18, but Belsuar escaped unscathed while Maiers No. 23 started to stumble, leaving an opening for Rob Kohler to swoop in for his fourth second-place finish on the year at Citrus. I could hear him back there the whole time, Belsuar said of Maier. He tried to run over me over there, and I had to hold him off. Im really starting to enjoy this Citrus track, Kohler said. My car is still just a little bit off. I was pushing the last time we were here, and I kind of got the push to go away. But somethings not quite perfect about it. Super Late Models returns to Citrus for another 25-lap event this Saturday. Modified Mini Stocks, Pure Stocks, Mini Stocks and Hornets also run.

Fact is, its UPTs new landscape is unique. BYU is in its fourth season as a football independent.

MONDAY, SEPTEMBER22, 2014 B7CITRUSCOUNTY(FL) CHRONICLEENTERTAINMENT PHILLIPALDER Newspaper Enterprise Assn.Judith Martin, who is better known as Miss Manners, said, We are born charming, fresh and spontaneous and must be civilized before we are fit to participate in society. To participate effectively in a bridge deal, we hope to find a fit with partner. This week we will look at the factors affecting your choice when you have two fits. First, should you prefer a 4-4 fit or a 5-3 fit? Almost always, you should pick the 4-4. If the 4-4 fit is a side suit, you will get at most four tricks. But if it is the trump suit, you will often get an extra trick by ruffing a loser in one hand or the other. And a 5-3 side-suit fit will usually provide two discards on the fourth and fifth cards. But if the 5-3 fit is the trump suit, it will rarely furnish a sixth trump trick from a ruff in the shorter trump hand. Look at todays deal. How does South get on in four hearts or four spades? In the auction, North might have started with a negative double to show his four hearts, especially as his singleton made his hand a tad strong for a single spade raise. After the spade raise, the South hand was just worth game, but he wisely showed his heart suit. Then North raised to four hearts, a tad worried about his weak trumps. Against four hearts, West should realize that East is highly unlikely to have an entry, so should start with three rounds of trumps. But South can easily restrict his losers to one spade and two trumps. In spades, West can cash his two high hearts and give his partner a heart ruff. Then Wests trump trick defeats the contract.

(N) (Live) Funny Home Videos Dear Annie: My brother, Ned, worked alongside my dad for many years. Now that Dad is getting up in years, Ned has taken over the business. Ned has had a drinking problem for a long time. Ten years ago, he landed a lucrative contract for the business, and my parents were able to put money in the bank. Since then, however, his drinking has become worse, and he has been unable to get any contracts at all. His temper has become volatile, and he briefly went to jail. He eats my parents out of house and home and ruins our family get-togethers by arguing with everyone. He threatens to sell his house, move to Hawaii and end his life if anyone tries to confront him. He refuses treatment. We are all worried about Ned, but mostly, we are concerned about my parents health. They dont know how to handle Neds irrational behavior anymore and want to close the business before they lose everything. What do you suggest? Worried Sis Dear Sis: If your parents still own the business, they ought to sell it, unless they can hire someone else to run it profitably. But if Ned is a part owner, your parents will need to consult an attorney. Neds drinking, his volatile temper and his threats are not within their control. He has to want help and may need to hit rock bottom to get there. In the meantime, your parents have to protect themselves. Start by contacting Al-Anon (al-anon-alateen. org). Dear Annie: I have owned all kinds of pets and have always loved them dearly and considered them family. I can understand signing their name on birthday cards, holiday cards, etc. But I was surprised when I received a sympathy card with the signatures of the husband and wife along with the pets name and paw print. Do you think this is appropriate? Still Grieving Dear Still: The dogs paw print changes the tone of the card from sympathetic to cute. It is not appropriate, but some folks simply dont consider how that type of card is going to be received by someone in mourning. We dont believe they meant to treat your grief lightly. Please forgive them. Our condolences on your loss. Dear Annie: I cant believe you told Mom that her arriving college freshman daughter should tolerate her new roommates boyfriend staying overnight in their dorm room. Obviously, the mom should get in touch with the roommates parents and tell them she vetoes this plan. The young couple can then be angry with the mom, not the new roomie. Or if need be, call the university and request a new roommate ASAP This is where the sexual revolution has led us. The most shameless behavior is supposed to be tolerated by everyone for fear of rocking the boat! Mother of Two College Students Dear Mother of Two: We didnt tell her to tolerate it. We told her to talk to her roommate and ask that the boyfriend spend his evenings elsewhere and also to request a new roommate as soon as it can be arranged. But heres where we disagree: We dont believe the parents should be working this out. This girl is now an adult, and part of the college experience is learning how to manage these types of situations without parental assistance. She needs to deal with this roommate on her own. We hope she will assert herself. Dear Readers: Today is Family Day (casafamilyday.org). Studies show that children who eat dinner with their parents have a reduced risk of substance abuse. Please try to make meals a family event) STASH MIGHTPREFIX NOTIFY Saturdays Jumbles: Answer: The backup quarterback was PASSING.
