What is the SQL command to return the field names of a table?
Say I have a table called myTable. What is the SQL command to return all of the field names of this table? If the answer is database specific then I need SQL Server right now but would be interested in seeing the solution for other database systems as well.
MySQL 3 and 4 (and 5): desc tablename which is an alias for show fields from tablename SQL Server (from 2000) and MySQL 5: select COLUMN_NAME from INFORMATION_SCHEMA.COLUMNS where TABLE_NAME = 'tablename' Completing the answer: like people below have said, in SQL Server you can also use the stored procedure sp_help exe...

What are the quickest and easiest ways to ensure existing web pages display well on mobile platforms?
The pages in question contain a lot of javascript and CSS. How well are these supported by mobile platforms generally? Is there a browser emulator (or equivalent tool) to assist testing?
Opera has an option to view pages as through a mobile device. I've found it useful in the past.

How do I set specific environment variables when debugging in Visual Studio?
On a class library project, I set the "Start Action" on the Debug tab of the project properties to "Start external program" ( NUnit in this case).

In Visual Studio 2008 and Visual Studio 2005 at least, you can specify changes to environment variables in the project settings. Open your project. Go to Project -> Properties...

How can I perform a Google search on different Google datacentres?
I would like to get up-to-date information on Google's index of a website, and it seems that results vary depending on which datacentre happens to process your search query.
You can use one of the many tools designed specifically for this. One of them is Google Datacenter Search at iWebTool. (It's really all about getting a list of data center IPs and sending the same GET variable to them as to google.com.)

I recommend AutoHotKey. Its syntax is not pretty, but most of the times you don't have to concoct your own scripts, because its community is so large and well organized.

Why do you not declare several variables of the same type on the same line?
Why is it bad practice to declare variables on one line? e.g. private String var1, var2, var3 instead of: private String var1; private String var2; private String var3;
I think that there are various reasons, but they all boil down to that the first is just less readable and more prone to failure because a single line is doing more than one thing. And all that for no real gain, and don't you tell me you find two lines of saved space is a real gain. It's a similar thing to what happens...

Not all soundcards support 24 bit sample playback, and even when they do, they often have to be exclusively opened in that mode. There is a similar issue with sample rates.

Moving to ASP.NET - VB or C#?
We have a large ASP classic code base but I'm looking to do future development in ASP.NET (and potentially in the future port across what we have). The natural choice of language seems to be VB (existing code is VBScript) but am I being too hasty? Does the choice of language, in the long run, even make a difference?
It's learning.Net (framework) that takes the time. The specific language doesn't matter and is more a matter of taste. I'd normally recommend trying a few play projects in both languages (and any others that may take your fancy), and then decide which one you're more comfortable with (or have more success with!)

How much resources do sleeping and waiting threads consume

For most cases, the resources consumed by a sleeping thread will be its stack space.

Why is "if not someobj:" better than "if someobj == None:" in Python?
I've seen several examples of code like this: if not someobj: #do something But I'm wondering why not doing: if someobj == None: #do something Is there any difference? Does one have an advantage over the other?
In the first test, Python try to convert the object to a bool value if it is not already one. Roughly, we are asking the object: are you meaningful or not? This is done using the following algorithm: If the object has a __nonzero__ special method (as do numeric built-ins, int and float ), it calls this method. It must ...

How can I access the classes loaded by Java Web Start when dynamically compiling code?
I am dynamically compiling code in my client application. When I start the application with Java Web Start I get an exception.

As it currently stands, you'll have to compile the code on the server. The server should not serve any code that might allow cross site attacks, so be very careful. The client can then use URLClassLoader.newInstance to load it.

Communication Gap: User vs Analyst-Designer
Normal practice is to use case studies, construct work- and data-flows, etc. But this does not necessarily create a shared vocabulary between the user/sponsor and the analyst-designer: one or the other, both normally, will have to acquire terms and views of the "internals" of the others area of expertise, and this usua...
Try to eliminate as many intermediate steps between the user and final implementer as possible. Every such step obscures and loses information.

While editing an aspx file I found both these opening tags used for seemingly the same thing. Is there a difference and if yes, what is it?
<%= is a equivalent to <% Repsonse.Write() You can write any content out here: for example <%=myProperty + " additional Text" %> <%# is a binding expression. You can retrieve any public value in the current context (for example in GridViews). But you cannot mix content here. Take a look at MSDN for more information.

Help needed for extending Asp.Net

The handling of app_offline.htm is hardcoded in the ASP.NET pipeline, and can't be modified: see CheckApplicationEnabled() in HttpRuntime.cs, where it throws a very non-configurable 404 error if the application is deemed to be offline.

The web services do allow a loosely coupled architecture.

I would say this practice promotes concentrating your efforts on the 'problem space' rather than the 'solution space'. Driving an emergent solution (the design) by studying and really getting to know and understand the domain. One of the practices (taken from XP) would be the writing of stories that occur in the proble...

Try one of the exception catchers, like madExcept. It can often help you find out what is happening inside your app at the time of trouble. In general though Delphi apps are fine in Vista, so there must be some interaction, perhaps user rights, that is causing trouble.

As far as I can tell (I haven't seen any definitive source on this),.NET doesn't have any support for XPath 2.0. I've read things that suggest its so, but I can't get any 2.0 XPath functions to run without providing custom function definitions. You can use an external library to get 2.0 compatability, however.

How to choose the max thread count for an HTTP servlet container?
I'm developing a restful Web service that runs as a servlet (using blocking IO) in Jetty. Figuring out the optimal setting for max threads seems hard. Is there a researched formula for deciding the max number of threads from some easily measurable characteristics of the rest of the setup?
Very simple and primitive one: max_number_of_threads = number_of_CPUs * C Where C depends on other factors of your application:-) Ask yourself following questions: Will your application be CPU intensive (lower C) or spend most time waiting for a third systems (higher C)? Do you need quicker response times (lower C) or ...

You can use OCIDefineArrayOfStruct to support fetching arrays of records. You do this by passing the base of the array to OCIDefineByPos, and use OCIDefineArrayOfStruct to tell Oracle about the size of the records (skip size). I believe that you then call OCIFetch telling it to fetch the array size. An alternative is t...

When is a language considered a scripting language?
What makes a language a scripting language? I've heard some people say "when it gets interpreted instead of compiled". That would make PHP (for example) a scripting language. Is that the only criterion? Or are there other criteria? See also: What’s the difference between a “script” and an “application”?
A scripting language is a language that "scripts" other things to do stuff. The primary focus isn't primarily building your own apps so much as getting an existing app to act the way you want, e.g. JavaScript for browsers, VBA for MS Office.

Triggering a .NET garbage collection externally
Is there a way to trigger a garbage collection in a.NET process from another process or from inside WinDBG? There are the Managed Debugging Assistants that force a collection as you move across a native/managed boundary, and AQTime seems to have button that suggests it does this, but I can't find any documentation on h...
John Cocktoastan's answer to use GC.Collect when in Visual Studio is the best option if there. I still can't find an alternative to actually do the collection under WinDBG but taking a step back to problem of "How much memory is reclaimable?" (see my comment to John's answer) I think there is an alternative by using a ...

How can I confirm a database is Postgres & what version it is using SQL?
I'm building an installer for an application. The user gets to select a datasource they have configured and nominate what type of database it is. I want to confirm that the database type is indeed Postgres, and if possible, what version of Postgres they are running by sending a SQL statement to the datasource.
Try this: mk=# SELECT version(); version ----------------------------------------------------------------------------------------------- PostgreSQL 8.3.3 on i486-pc-linux-gnu, compiled by GCC cc (GCC) 4.2.3 (Ubuntu 4.2.3-2ubuntu7) (1 row) The command works too in MySQL: mysql> select version(); +-----------------------...

Letting several assemblies access the same text file
I've got many assemblies/projects in the same c#/.net solution. A setting needs to be saved by people using the web application gui, and then a console app and some test projects need to access the same file. Where should I put the file and how to access it? I've tried using "AppDomain.CurrentDomain.BaseDirectory" but ...
Personally, I would be leveraging the database because the alternative is either a configuration headache or is more trouble than it's worth. You could configure each application to point to the same file, but that becomes problematic if you want to move the file. Or you could write a service to manage the file and exp...

Why is there no ForEach extension method on IEnumerable?
Inspired by another question asking about the missing Zip function: Why is there no ForEach extension method on the IEnumerable interface? Or anywhere? The only class that gets a ForEach method is List<>. Is there a reason why it's missing, maybe performance?
There is already a foreach statement included in the language that does the job most of the time. I'd hate to see the following: list.ForEach( item => { item.DoSomething(); } ); Instead of: foreach(Item item in list) { item.DoSomething(); } The latter is clearer and easier to read in most situations, although maybe a b...

A named semaphore or mutex can do this for you on a single machine. Use e.g. TMutex from SyncObjs, and use one of the constructors which takes a name argument. If you use the same name in all the applications, they will be synchronizing over the same kernel mutex. Use TMutex.Acquire to access, and TMutex.Release when y...

The Log Files (binary Logs) were my first thought too. If you knew how they did things you would shudder. For every row there are many many entries in the log as pieces are added and changed.

What is the difference between a non-secure random number generator and a secure random number generator?
As the title says: What is the difference between a non-secure random number generator and a secure random number generator?
No computationally feasible algorithm should: recover the seed, or predict the "next bit" for a secure random number generator. Example: a linear feedback shift register produces lots of random numbers out there, but given enough output, the seed can be discovered and all subsequent numbers predicted.

Thumbnail image from .3gp file
Does anybody know how to get thumbnail (still image) from 3gb video file? First frame or something like that. I'm using.net, but solution can be in any language (managed or native), or third-party product.
This is using ffmpeg on Linux and called from PHP, but if you can use ffmpeg then that dosen't matter: ffmpeg -i path/to/your/video.3gp -an -ss 00:00:00 -t 00:00:01 -y -s 400x300 path/to/your/image%d.jpg Note the "%d"; you are only generating one frame but ffmpeg still needs this so it knows where to put the number whe...

I'm using localConnection in AS3 to allow several flash applications to interact with a central application. (Some are AS2, some AS3).

It would seem more organised to communicate with each Flash application separately, although I think it will work either way.

Encoding spaces with the javascript encodeURIComponent function
Why does the JavaScript function encodeURIComponent encode spaces to the hex Unicode value %20 instead of +. Should URI parameters not spaces to +? ­­­­­­­­­­­­­­­­­­­­­­­­­­­
Spaces encode to %20, I believe that's their ASCII character code. However, developers have taken a shine to encoding spaces to + because it generates URLs that are readable and typeable by human beings.

I was wondering are there any security concerns with adding crossdomain.xml to the root of an application server? Can it be added to any other parts of the server and are you aware of any work arounds that dont require the server to have this file in place? Thanks Damien
By adding the crossdomain.xml, the main security concern is that flash applications can now connect to your server. So if someone logs into your site, and then browses over to another website with a malicious flash app, that flash app can connect back to your site. Since it's in a browser, cookies are shared to the fla...

The most efficient way to implement an integer based power function pow(int, int)
What is the most efficient way given to raise an integer to the power of another integer in C? // 2^3 pow(2,3) == 8 // 5^5 pow(5,5) == 3125
Exponentiation by squaring. int ipow(int base, int exp) { int result = 1; for (;;) { if (exp & 1) result *= base; exp >>= 1; if (!exp) break; base *= base; } return result; } This is the standard method for doing modular exponentiation for huge numbers in asymmetric cryptography.

Can you use the Phoenix compiler as a more powerful NGEN?
In case you don't know of Phoenix, it's a compiler framework from Microsoft that's apparantly going to be the foundation of all their new compilers.

Without knowing too much about Phoenix, in order to have a.NET app run natively you're going to also need a native version of the framework, unless you don't use the framework (which is pretty much impossible). Also the CLR includes garbage collection, assembly loading, etc, so dumping the interpreting part of the CLR ...
