// The class SubsetFunction<T> represents a function on the subsets of
// {0, 1, ..., N-1} (or equivalently the integers [0, 2^N)) with values in T
// and offers a variety of standard operations (i.e. xor-convolution).
// The time complexities of the various operations are optimal.
// Even if not heavily optimized (in order to maintain a good readability),
// these implementations shall be fast enough in all situations.

Highly composite numbers list
#!/usr/bin/env python3
# This program prints all hcn (highly composite numbers) <= MAXN (=10**18)
# The value of MAXN can be changed arbitrarily. When MAXN = 10**100, the
# program needs less than one second to generate the list of hcn.
from math import log
MAXN = 10**18

How to have Latex in Empathy (using Mathjax).
View LatexInEmpathy
This guide explains how to modify the classic theme of empathy (minimal one... the best one!) in order to have latex in empathy's chat windows.
The two files PATCH_Info.plist, PATCH_Content.html are in this same gist.
First of all install mathjax:
sudo apt-get install libjs-mathjax libjs-mathjax-doc fonts-mathjax fonts-mathjax-extras
Open /usr/share/adium/message-styles
Make a copy of Classic.AdiumMessageStyle in the same folder and rename it LatexClassic.AdiumMessageStyle
Open /LatexClassic.AdiumMessageStyle/Contents
Modify Info.plist substituting its content with the content of PATCH_Info.plist
