Correct way to write line to file?
...ring instead of \n" would require newline="" otherwise you'd get \r\r\n on Windows. There is no reason to futz about with os.linesep at all.

Show the progress of a Python multiprocessing pool imap_unordered call?
...map_async resulted in much faster execution, though the result object is a bit different. Instead, the result object from map_async has a _number_left attribute, and a ready() method:
p = multiprocessing.Pool()
rs = p.map_async(do_work, xrange(num_tasks))
p.close() # No more work
while (True):

Compile time string hashing
...
This is a little bit late, but I succeeded in implementing a compile-time CRC32 function with the use of constexpr. The problem with it is that at the time of writing, it only works with GCC and not MSVC nor Intel compiler.
Here is the code ...

Efficient way to apply multiple filters to pandas DataFrame or Series
...cient since it doesn't make a copy of the data. However, my scenario is a bit more tricky than your example. The input I receive is a dictionary defining what filters to apply. My example could do something like df[(ge(df['col1'], 1) & le(df['col1'], 1)]. The issue for me really is the dicti...
Simple proof that GUID is not unique [closed]
...
A GUID is theoretically non-unique. Here's your proof:
GUID is a 128 bit number
You cannot generate 2^128 + 1 or more GUIDs without re-using old GUIDs
However, if the entire power output of the sun was directed at performing this task, it would go cold long before it finished.
GUIDs can be ...

FNV is also designed for variable lengths of data, whereas the way we're using it here is always for the same number of field values.
