How to read the contents of a local image into a base64 string in MonoTouch
I am trying to read the contents of an image stored in the Documents folder for my application into a string, using base64 encoding. I have the image location as a url; so, for example, I could have the following url for the image: file://localhost/var/mobile/Applications/40A88352-7F78-4085-856B-9621541774ED/Documents/...
If you are getting VMDisconnectedException at startup, it probably means that the FinishedLaunching method does not return in time and iOS kills your app. If you need to load that file at startup, wrap your code in an async method or thread that will allow FinishedLaunching to return in time: byte[] imgData; string bas...

How do I convert/reshape a data frame in long format to a wide format without aggregating the records?
From this: > test <- data.frame(x = c("a","a","a"), y = c("b","b","c"), z = c(1,2,1)) > test x y z 1 a b 1 2 a b 2 3 a c 1 To this: x b c 1 a 1 NA 2 a 2 NA 3 a NA 1
Since the x column in the test data-frame doesn't uniquely identify the rows, and yet you don't want to do any aggregation, you need to augment the data-frame with a unique id column, and then use dcast() from the reshape2 package: require(reshape2) test$id <- 1:nrow(test) > dcast(test, id + x ~ y, value_var = 'z')[,-...

Just use ImageMagick's convert. convert foo.pdf foo.png You can have more precise control over the page number with format strings, e.g.: convert foo.pdf "foo-%03d.png" And of course there are the myriad other ImageMagick options, but the basic command above is all you need most of the time.

Custom logger in Rails 3?
I want to have a custom logger for my application, which of course logs to a different file, someone asked a question: Setting up the logger in rails 3 But I want to have a logger which I can call with my own class name like: StatusLogger.info "something happend!!!" How can I do this?
You could do that with this code logfile = File.open('/path/to/log.log', 'a') StatusLogger = Logger.new(logfile) StatusLogger.info 'Hello World!' And you would most likely configure this in an initializer file, or you could do it in an environment file if you wanted.

The parameters you want to extract are called extras. You can extract them this way: Bundle extras = this.getIntent().getExtras(); String[] recipients = (String[]) extras.get(EXTRA_EMAIL); There are several extras you can get from an ACTION_SEND intent (e.g. EXTRA_EMAIL, EXTRA_CC, EXTRA_BCC, EXTRA_SUBJECT).

return is a reserved keyword in the Java Programming Language(tm). But luckily there is an alternative spelling. Try param['return'] instead.

Slightly unorthodox, but you could use recursion. So in your example: def recursive_search(tags, results_queryset): if len(tags) > 0: result_qs = result_queryset.filter(tags_name=tags[0]) if result_queryset.exists(): return filter_recursion(tags[1:],result_queryset) else: return None return result_queryset tags = ["co...

How do I use enumerated datatypes in Objective-C?
I'm working on several iOS projects where I think enumerated datatypes would be helpful to me. For example, I have a game where the player can walk in several directions.

That sounds like the right thing to do. It's really simple to create enums in Objective-C using C-style type definitions. For example, in one of my header files, I have the following type definition: typedef enum { CFPosterViewTypePoster = 0, CFPosterViewTypeStart, // 1 CFPosterViewTypeEnd, // 2.... // 3 } CFPosterView...

Trouble defining multiple self-referencing foreign keys in a table
I have some code here. I recently added this root_id parameter.

Thus, I want to be able to compare Project.directory to File.root. If that is true...
My understanding is that defining a FK foo_id into table Foo implicit creates a foo attribute to which you can assign a Foo object. No, it doesn't. In the snippet, it just looks like it is being done for Project.directory, but if you look at the SQL statements being echo'ed, there is no INSERT at all for the projects t...

Is Hbase or BigTable like massive Matrix Store?
I have been doing some research on the HBase and Google's BigTable. HBase and BigTable look like a massive Matrix store for me. Each row key is mapped to a big m*n matrix(X), which m is the number of total rows, n is the number of total columns. And X consists total of Q k*2 matrices. Which m=Q*k, n=2*Q Is this right? ...
There are different logical ways of looking at HBase. You certainly can use it as a large sparse matrix. Your description seemed slightly off to me however. A table is a matrix; rows are composed of column families; column families are composed of column qualifiers. Each column qualifier can have N versions. Practicall...

Node.js: chunked transfer encoding

Text files do seem to work fine, but that could be coincidental. Is my header "200 OK" or need it to be "100"? Is one header sufficient?
If you're doing chunked transfer encoding, you actually need to set that header: Transfer-Encoding: chunked You can see from the headers returned by google, which does chunked transfers for the homepage and most likely other pages: HTTP/1.1 200 OK Date: Sat, 04 Jun 2011 00:04:08 GMT Expires: -1 Cache-Control: private, ...

Using only 1 resource file instead of 1 resource file per form/other strings
We are localizing our forms and strings in a project and are having a problem; Visual Studio creates a resource file for each form when setting Localizable to true. It's nothing more than a minor nuisance having to send all of the resource files to translators, but is it possible to get VS to use a global resources fil...
As others already said, it is possible to use global resource file manually. I believe that it is actually more problematic and less maintainable but still possible. Now onto why MS decided on one resource file per form. Well, from Internationalization point of view, this solution is better. On one hand it gives transl...

What is a Sandbox
When anti-viruses run some application in a virtual environment called a "sandbox", how does this sandbox precisely work from the Windows kernel point of view? Is it hard to write such a sandbox?
At a high level such sandboxes are kernel drivers which intercept calls to APIs, and modify the results those APIs return using hooking. How an entire sandboxing solution works under the hood though, could easily fill several books. As for difficulty, it's probably one of the harder things you could ever possibly write...

Where is the web server root directory in WAMP?
Also is the web server root directory the place where you put your site files and later acces them with localhost/file_name in the browser?
If you installed WAMP to c:\wamp then I believe your webserver root directory would be c:\wamp\www, however this might vary depending on version. Yes, this is where you would put your site files to access them through a browser.

How to get pattern rules to match file names with spaces in Makefile?
In the GNU make docs, '%' is documented to match "any nonempty substring". However, it seems it actually only matches non-empty substrings that do not contain whitespace. For example, say you do this: mkdir /tmp/foo cd /tmp/foo echo 'int main() { return 0; }' > "test.c" echo 'int main() { return 0; }' > "test space.c" ...
I don't believe so. The notion of a list of whitespace-separated tokens being passed around as a string is pretty deeply ingrained in make. Those lists are parsed and reparsed. There's a reason why spaces in directory and file names is considered bad practice in the UNIX world.

I have a collection of movieclips, I would like to create a clone (a new instance) of a instance everytime I create a new object. For example var s:Star = new Star(); // star-shaped movielcip addChild(s); // then I want to duplicate an instance of s and add it beside s For an example like above, it's simple enough to c...
moses' solution is correct. What is the purpose of the clone, where you wouldn't need to know the name of the clone to reference it? One option is you could create an array to store your references in so you don't need to explicitly name them. Using moses' code... var clones:Array = new Array(); for each (var star:Star...

How to extend a Cocoa protocol in a category to avoid "not found in protocol(s)" warning?
This seems like a simple thing, but my brain doesn't seem to be working today, and my searches haven't turned up a helpful answer. I have lots of code that extends Cocoa classes via categories (it's open source, too). Some methods want to call the delegate; the old code used informal protocols to do this, but now when ...
I think this is because the NSOutlineView delegate is now typed as id rather than a plain id as it was in the 10.5 SDK. The category is declared on NSObject, but the compiler doesn't see the delegate object as inheriting from NSObject, so it doesn't recognize that it would respond to the message. Before, since the dele...

I think I answered my own question -- The timestamp in the update..updt is the moment that the " cleartool update " was started, but it's the time on the local machine - which may be different from the time on the clearcase server machine.

RETURN VALUE On success, the PID of the child process is returned in the parent, and 0 is returned in the child. On failure, -1 is returned in the parent, no child process is created, and errno is set appropriately. So, in the parent process, fork() returns the pid of the child process that was created.

I'm only guessing this is the problem, but if you call the replace_fav_url() function more than once, it will bind an additional click event to a.fav. And will continue to do so each time you call it. If you change the number of a.fav elements in any way, it would be better to use delegate() or live() to bind a click e...

My List in Java is coming out null, instantiating it doesn't seem to work... help?
Searched around the site and google nothing seems to come in for what I'm sure is a super simple problem. So I have a list I declare like so: private List mList; When I try to do a method on it like mList.add(...); it doesn't work, returns a null pointer exception. I tried to instantiate the List like so: public Class(...
A variable must be initialized before it can be used. Otherwise it is null and you get NullPointerExceptions. Java has interfaces, which are like classes with only methods defined. However you cannot create real objects from them. They just serve to define the contract. java.util.List is such an interface. You have to ...

SemaphoreSlim.Wait( CancellationToken ) proper try/finally for OperationCancelledException?
How should I structure the try/finally when using a SemaphorSlim with cancellation token so that OperationCancelledException is handled correctly? In Option A, cancelling the token source throws OperationCancelledException but does not call Release(). In Option B, cancelling the token source throws OperationCancelledEx...
Option A is more correct here. You do not need to Release the SemaphoreSlim when you cancel, as you never actually acquire and increment its count. As such, you don't want to release unless your Wait call actually succeeded. From this MSDN Page on using Semaphore and SemaphoreSlim: It is the programmer's responsibility...

How to tell version of .NET used for a delivered project with no project or solution file?

You can't reliably tell which version the code was written for, since (most) code written using only features of an earlier version compiles under newer versions. What you can do though is to try to build the project under different versions of the runtime, which is as close as you can get, I think. Also, the whole.Net...

DLR LambdaExpressions and the System.Runtime.CompilerServices.Closure object
I'm working on a small programming language for the Microsoft DLR, and having a bit of a problem invoking my anonymous methods.

It would be helpful if you could share the body that you're compiling as that would contain the actual closure and how you're invoking it. My guess is that you are attempting to invoke the resulting delegate "by hand" somehow instead of holding onto something of the delegate object and simply generating an Invoke expre...

Very simple. If you have text in your text view and than create 1 date Variable and convert it to NSString. And use following assignment to have your goal finished. yourTextView.text = [NSString stringWithFormat:"%@ %@",yourStringDateVariable,yourTextView.text]; Does this make sense?

overlay on clickable region - CSS
Is there a way I can have a partially transparent image (or anything really) overlay a clickable region using XHTML and CSS?
@thirtydot If you know of a solution that works in only one browser I still would love to here it! Although the more support the better. You can use pointer-events: none. Browser support: http://caniuse.com/pointer-events (works everywhere except IE10 and older) http://jsfiddle.net/QC5Yw/

Adding Controls to Controls in codebehind

Where should transaction records go? Flat file or Database
I'm developing a Java Enterprise Application which needs to write transaction records either to flat files or directly to a relational database. Transaction records are records which show when the transaction starts, ends, transaction status (success/failure) and also data unique to this transaction. These transaction ...
If you DO use a flat file, you'll need to worry about locking and flushing and all of that garbage. Furthermore, it can only live in one place which makes it a pain if you ever want the app to scale. Go with the database unless downtime is a REALLY big concern.

Move or Named Return Value Optimization (NRVO)?
Lets say we have the following code: std::vector f() { std::vector y;... return y; } std::vector x =... x = f(); It seems the compiler has two approaches here: (a) NRVO: Destruct x, then construct f() in place of x. (b) Move: Construct f() in temp space, move f() into x, destruct f(). Is the compiler free to use eithe...
The compiler may NRVO into a temp space, or move construct into a temp space. From there it will move assign x. Update: Any time you're tempted to optimize with rvalue references, and you're not positive of the results, create yourself an example class that keeps track of its state: constructed default constructed move...

MKMapView not updating when i call setCoordinate
This is my second question today and the first was an incredibly stupid question so I'm fully expecting this one to be as well. I have a view with an embedded MKMapView.

In the place that you want to get at it from, set up an outlet. In the.h file, declare a mapview property MKMapView *mapView; then declare its property with an IBOutlet @property (nonatomic, retain) IBOutlet MKMapView *mapView; You should be able to control-drag from File's Owner in your IB file to the mapview in your ...

The first one WorkspaceViewModelFactory. Quote #1 from Capitalization Conventions When an identifier consists of multiple words, do not use separators, such as underscores ("_") or hyphens ("-"), between words.

Rand() function cause error when I replace static value with random value
What am I doing wrong I have this script, and added the $randnumber = rand(100, 500); function to it, this should generate a random number for me between 100 and 500. $randnumber = rand(100, 500); function word_limiter( $text, $limit = $randnumber, $chars = '0123456789' ) The problem is that it gives me a error: Parse ...
That is a syntax error. You cannot assign the value of an expression as a default value. Default values can only be constants. Instead of doing that, you could be doing something like: function word_limiter ($text, $limit = null, $chars = '0123456789') { if ($limit === null) { $limit = rand(100, 500); } //... }

iPhone OS: EXC_BAD_ACCESS and xcode freezing while debugging on device?

Considering I use 2GB of RAM without even loading Xcode, your 1GB could well be a problem. It also could be a recursive bug that causes the debugger a hell of a lot of work by having an enormous stack trace.
