When is a file just a file?
So, you're writing a web application and you have several areas of the site where the user can upload files. My basic working method for this is to store the actual file on the server, and have a database table that connects the stored filename to the record it relates to. My question is this: Should there be a differe...
From your example, there is an argument for two tables, as you have files that can be associated with two different things. CVs, photos are associated with a user. attachments are associated with a CMS page. If you put these in one table, (and you want to allow users to have more than one photo or cv) then you need two...

Experience with Hadoop?
Have any of you tried Hadoop? Can it be used without the distributed filesystem that goes with it, in a Share-nothing architecture? Would that make sense? I'm also interested into any performance results you have...
Yes, you can use Hadoop on a local filesystem by using file URIs instead of hdfs URIs in various places. I think a lot of the examples that come with Hadoop do this. This is probably fine if you just want to learn how Hadoop works and the basic map-reduce paradigm, but you will need multiple machines and a distributed ...

Large, Complex Objects as a Web Service Result
Hello again ladies and gents! OK, following on from my other question on ASP.NET Web Service Results, Proxy Classes and Type Conversion. I've come to a part in my project where I need to get my thinking cap on. Basically, we have a large, complex custom object that needs to be returned from a Web Service and consumed i...
The.Net XML (de)serialisation is pretty nicely implemented. At first thought, I don't think this is a bad idea at all. If the two applications import the same C# class(es) definition(s), then this is a relatively nice way of getting copy-constructor behaviour for free. If the class structure changes, then everything wi...

Anyone know a quick way to get to custom attributes on an enum value?
This is probably best shown with an example. I have an enum with attributes: public enum MyEnum { [CustomInfo("This is a custom attrib")] None = 0, [CustomInfo("This is another attrib")] ValueA, [CustomInfo("This has an extra flag", AllowSomething = true)] ValueB, } I want to get to those attributes from an instance...
This is probably the easiest way. A quicker way would be to Statically Emit the IL code using Dynamic Method and ILGenerator. Although I've only used this to GetPropertyInfo, but can't see why you couldn't emit CustomAttributeInfo as well. For example code to emit a getter from a property public delegate object FastPro...

This is a compiler bug. Here's another post confirming it's a known issue. I've got the same issue in one of my projects and there's no way to prevent it from being triggered unless you have some way of avoiding the use of OdbcParameter.

Recommendation for javascript form validation library
Any recommendations for a javascript form validation library. I could try and roll my own (but I'm not very good at javascript). Needs to support checking for required fields, and preferably regexp validation of fields.
I've used this library for a couple of personal projects. It's pretty good, though I have had to make my own modifications to it a couple of times - nothing major, though, and it's easy enough to do so. I'm sure you already do this, but also validate all of your information on the server-side, as well. Client-side-only...

best practice for releasing Microsoft dll's in setup
I'm working on a setup which wants to include the Microsoft.Web.Services3 (WSE 3.0) DLL. However, I typically do not like including Microsoft DLL's in our installs except by way of Microsoft's redistributables. There is both a developer and a redist install package available from Microsoft. So, as a best practice, shou...
Usually, redistributing any of Microsoft DLLs outside of the redistributable package is forbidden by their EULA, so you might first want to check the appropriate EULA for that DLL. Generally, I would prefer the redist package since that makes sure that it's correctly "registered" into the system, i.e. if you install a ...

Try the entry_points.console_scripts parameter in the setup() call. As described in the setuptools docs, this should do what I think you want.

Using an ocx in a console application
I want to quickly test an ocx. How do I drop that ocx in a console application. I have found some tutorials in CodeProject and but are incomplete.
Sure..it's pretty easy. Here's a fun app I threw together. I'm assuming you have Visual C++. Save to test.cpp and compile: cl.exe /EHsc test.cpp To test with your OCX you'll need to either #import the typelib and use it's CLSID (or just hard-code the CLSID) in the CoCreateInstance call. Using #import will also help def...

When do you use sIFR?

You use sIFR moderately, say for headlines. Try not to use it for links, because links in Flash don't work as well as normal HTML links. It also makes little sense to use sIFR only for text that never changes, an image would work a lot better. I haven't heard about the upside-down problem in a few years now, but in any...

How to round up the result of integer division?
I'm thinking in particular of how to display pagination controls, when using a language such as C# or Java. If I have x items which I want to display in chunks of y per page, how many pages will be needed?
Found an elegant solution: int pageCount = (records + recordsPerPage - 1) / recordsPerPage; Source: Number Conversion, Roland Backhouse, 2001

How to generate a core dump in Linux on a segmentation fault?
I have a process in Linux that's getting a segmentation fault. How can I tell it to generate a core dump when it fails?
This depends on what shell you are using. If you are using bash, then the ulimit command controls several settings relating to program execution, such as whether you should dump core. If you type ulimit -c unlimited then that will tell bash that its programs can dump cores of any size. You can specify a size such as 52...

You can also use TortoiseSVN for editting the proxy settings. TortoiseSVN saves the settings in the registry in the common location that all Subversion clients (by default) use. UPDATE: A proxy settings dialog is now implemented in the AnkhSVN daily builds. It will be available in the next release.

My best bet why it happens is because there is a native-managed-native boundary to cross. The native part doesn't forward the managed exceptions correctly and there is not much that can be done. I am still hoping for a better answer though.

Copying Files over an Intermittent Network Connection

The files involved are...
I'm unclear as to what your actual problem is, so I'll throw out a few thoughts. Do you want restartable copies (with such small file sizes, that doesn't seem like it'd be that big of a deal)? If so, look at CopyFileEx with COPYFILERESTARTABLE Do you want verifiable copies? Sounds like you already have that by verifyin...

If you're planning on coding against a sql database using.NET, skip ADO and go directly to Linq. You will NOT miss anything. Oh, also, Joe Celko. If you see his name on an article or a book about SQL, read it.

SQL Server 2005 insert trigger not inserting enough records

Your trigger is only using the first row from 'Inserted'. This is a common misunderstanding when dealing with SQL triggers for the first time. The trigger fires per update not per row. For example if you do the following:- update products set title = 'geoff de geoff' this would update all the products, but a trigger on...

You'll also want to make sure that your SSH system is well secured to prevent people from logging in as your Capistrano bot. I'd suggest restricting access to password-protected key pairs.

Elegant way to remove items from sequence in Python?
When I am writing code in Python, I often need to remove items from a list or other sequence type based on some criteria.

For example, you can't do this: for name in names: if name[-5:] ==...
Two easy ways to accomplish just the filtering are: Using filter: names = filter(lambda name: name[-5:]!= "Smith", names) Using list comprehensions: names = [name for name in names if name[-5:]!= "Smith"] Note that both cases keep the values for which the predicate function evaluates to True, so you have to reverse the...

Best way to bind Windows Forms properties to ApplicationSettings in C#?

If you open your windows form in the designer, look in the properties box. The first item should be "(ApplicationSetting)". Under that is "(PropertyBinding)". That's where you'll find the option to do exactly what you want.

I am not clear if you need to share a dataset, since you have some SQL results that you need to use twice, and don't want to re-compute the same data twice, or you want to do something regarding parameters.

The Convert.ToXXX() methods are for objects that might be of the correct or similar type, while.Parse() and.TryParse() are specifically for strings: //o is actually a boxed int object o = 12345; //unboxes it int castVal = (int) 12345; //o is a boxed enum object o = MyEnum.ValueA; //this will get the underlying int o...

Converting List<Integer> to List<String>
I have a list of integers, List and I'd like to convert all the integer objects into Strings, thus finishing up with a new List. Naturally, I could create a new List and loop through the list calling String.valueOf() for each integer, but I was wondering if there was a better (read: more automatic ) way of doing it?
As far as I know, iterate and instantiate is the only way to do this. Something like (for others potential help, since I'm sure you know how to do this): List oldList =... /* Specify the size of the list up front to prevent resizing. */ List newList = new ArrayList<>(oldList.size()); for (Integer myInt: oldList) { newL...

Random integer in VB.NET
I need to generate a random integer between 1 and n (where n is a positive whole number) to use for a unit test. I don't need something overly complicated to ensure true randomness - just an old-fashioned random number. How would I do that?
To get a random integer value between 1 and N (inclusive) you can use the following. CInt(Math.Ceiling(Rnd() * n)) + 1

Are foreign keys really necessary in a database design?
As far as I know, foreign keys (FK) are used to aid the programmer to manipulate data in the correct way. Suppose a programmer is actually doing this in the right manner already, then do we really need the concept of foreign keys? Are there any other uses for foreign keys? Am I missing something here?
Foreign keys help enforce referential integrity at the data level. They also improve performance because they're normally indexed by default.
