Convert python datetime to epoch with strftime
... mktime() may also fail for past/future dates if it doesn't use the tz database and if the local timezone may have different utc offsets over the years e.g., Europe/Moscow in 2010-2015 -- use UTC time (as in the question) or timezone-aware datetime objects instead.

Unicode Processing in C++
...uilt in facilities for it. That isn't always a possibility with older code bases though, with the standard being so new at present.

Analyze audio using Fast Fourier Transform
...ars this should not be done as antti suggest, by dividing the data equally based on the number of bars. The most useful would be to divide the data into octave parts, each octave being double the frequency of the previous. (ie. 100hz is one octave above 50hz, which is one octave above 25hz).

Java equivalent to C# extension methods
...werful tool. The main thing there is ability to override different methods based on different generic’s parameters instantiation. This is similar to Haskell’s type classes, and in fact, it looks like they are in C# to support C#’s Monads (i.e. LINQ). Even dropping LINQ syntax, I still don’t ...
