All the code in the web folder should be backed by SVN commits, shouldn't it?
If this is the case you should easily be able to track the problem down just by looking through your SVN logs at the last few changes that got committed.

How to retrieve an element from a set without removing it? |
|python| |
Suppose the following:
>>>s = set([1, 2, 3])
How do I get a value (any value) out of s without doing s.pop()? I want to leave the item in the set until I am sure I can remove it - something I can only be sure of after an asynchronous call to another host.

To say that `SELECT COUNT(*) vs COUNT(1)` results in your DBMS returning "columns" is pure bunk.

I'm not sure about other databases, but for SQL Server I recommend the Execution Plan. It very clearly (albeit with lots of vertical and horizontal scrolling, unless you've got a 400" monitor!) shows what steps of your query are sucking up the time.

1. From `View` menu, select `Labels...` to open the Labels dialog.

3. Type in label name as "Release 1.2.3.4", check `Frozen`, and hit `OK`.

Testing 52! possibilities is of course impossible. Instead, try your shuffle on smaller numbers of cards, like 3, 5, and 10. Then you can test billions of shuffles and use a histogram and the chi-square statistical test to prove that each permutation is coming up an "even" number of times. |
How about [Conditional breakpoints][1]? You could try for various conditions like first element value is zero or non zero, etc??

I'll take a stab at this.
Python and Ruby are duck-typed. To generate any maintainable code in these languages, you pretty much have to use test driven development. As such, it is very important for a developer to easily inject dependencies into their code without having to create a giant supporting framework.

It would be helpful if you can explain why you want to get this information. But I suspect that the method both most reliable and most general is going to be the PublicKeyToken. Yes, there's more than one, but it's going to be a finite list and one that doesn't change very often.

For the iPhone there's currently no such notion as Open Source as the Apple iPhone SDK NDA forbids publishing code. They also forbid posting code on any non-Apple site or even non-Apple discussion forums on iPhone development. As soon as the NDA expires (will it ever?) we'll start having Open Source iPhone apps. |
I think Flash should be limited to online games, videos and animation. Otherwise use html and Ajax. It's a web standard and supported by almost all devices.
AFAIK, the iPhone doesn't support Flash. That's a fast growing segment you're blocking out already. Keep it simple and efficient. |
To the best of my knowledge, there is not. It seems that you may be better off using another hash instead of %ENV. If you are calling many outside modules and want to track the same variables across them, a Factory pattern may work so that you're not breaking DRY, and are able to use a case-sensitive hash across mult... |

Yeah, those bastard crashes are the hardest to fix. Fortunatly, there are some steps you can do that will give you clues before you resort to manually looking at the code and hope to find the needle.
