How do I fix a NoSuchMethodError?
...en running it.
Look at the stack trace ... If the exception appears when calling a method on an object in a library, you are most likely using separate versions of the library when compiling and running. Make sure you have the right version both places.

Is there a way to reduce the size of the git folder?
...
I'm not sure what you want. First of all, of course each time you commit/push the directory is going to get a little larger, since it has to store each of those additional commits.

...)
Details on its workings are as follows:
The ps gives you the list of all the processes.
The grep filters that based on your search string, [p] is a trick to stop you picking up the actual grep process itself.
The awk just gives you the second field of each line, which is the PID.
The $(x) cons...
Can hash tables really be O(1)?
...f your objects are variable size and an equality check requires looking at all bits then performance will become O(m). The hash function however does not have to be O(m) - it can be O(1). Unlike a cryptographic hash, a hash function for use in a dictionary does not have to look at every bit in the i...
UTF-8, UTF-16, and UTF-32
...ere UTF-16 remains at just 2 bytes for most characters.
UTF-32 will cover all possible characters in 4 bytes. This makes it pretty bloated. I can't think of any advantage to using it.

Most pythonic way to delete a file which may not exist
...this takes even more lines and looks very ugly, it avoids the unnecessary call to os.path.exists() and follows the python convention of overusing exceptions.
It may be worthwhile to write a function to do this for you:

try:
os.remove(filena...
Which icon sizes should my Windows application's icon include?
... 24, 32, 40, 48, 64, 96, 128 and 256. Then I checked which image is shown. All these were done with normal 96dpi. If using a larger DPI, the larger sizes may be used (only checked this a bit in Windows 7). The results:
Windows XP:
