Cool page about (semi)numerical algorithm, including a book in progress, an open source library and a number of interesting links. Also has a mirror of hakmem. The author has also published a book about pi.
Self-initializing quadratic sieve (SIQS), on a 2GHz Opteron, a 95 digit factorization takes 4 hours, and a 100-digit factorization takes just under 12 hours (possibly more). Public domain library for integer factorization, implementing Pollard-rho, ECM, self-initializing Quadratic Sieve and parts of NFS.

With the help of http://web.archive.org/web/20110723030828/http://www.boo.net/~jasonp/qs.html, I could locate the repository https://sourceforge.net/projects/msieve/files/msieve/ which has been updated 2016-11-11. I changed the URL for the bookmark to the sourceforge repository.
Yet another language for numerical computation. Developed at Boeing, claims to be much faster than Octave, RLab and "old" Matlab. Can read Matlab binary files.
