Modulo operation with negative numbers
.../b is representable:
(a/b) * b + a%b shall equal a
This makes sense, logically. Right?
Let's see what this leads to:
Example A. 5/(-3) is -1
=> (-1) * (-3) + 5%(-3) = 5
This can only happen if 5%(-3) is 2.
Example B. (-5)/3 is -1
=> (-1) * 3 + (-5)%3 = -5
This can only happen if (...
PUT vs. POST in REST
...y exists, so sending the same request twice has no effect. In other words, calls to PUT are idempotent.
The RFC reads like this:
The fundamental difference between the POST and PUT requests is reflected in the different meaning of the Request-URI. The URI in a POST request identifies the resour...

Why does a return in `finally` override `try`?
...'t always execute in all cases due to a pretty serious browser bug. Specifically – if an exception is thrown in a try-finally block that isn't surrounded by a higher level try-catch, then the finally block won't execute. Here's a test case jsfiddle.net/niallsmart/aFjKq. This issue was fixed in IE8...

I agree. As I said, I just wasn't initially sure if the form property was extensively implemented in all common browsers. I've edited my answer to more explicitly list this as the better option while I'm leaving closest as a tidbit if this w...

So, if you had a script called my_shell_script:

...his greedy algorithm returns optimal solutions, by the following logic. We call a prefix (partial solution) safe if it extends to an optimal solution. Clearly the empty prefix is safe, and if a safe prefix is a whole solution then that solution is optimal. It suffices to show inductively that each g...
