Where in space-time may you be? Is this a singularity, for which the laws are unknown yet? More importantly, is there an amplitude for you to return home? Were you dragged to the adventure of your life? Sorry, not today —it's just my wacky® home on WWW, where i call eigenhome. It's just a single html page today, we'll see what time will bring (or take away).
Okay, there exists comprehensive libraries such as LAPACK, BLAS (public-domain sources).
So why did i bother? The story is, i once needed astronomical
precision for matrix operations -majorly multiplication and
finding eigenvalues-. My requirement was much beyond native FPU
types, so i reluctantly switched to GMP, which decreased the
computation speed drastically, but well, it's much
better than nothing! So i fixed the problem about arithmetics
operations, but the problem persisted, becauase i was still using
some external libraries (BLAS and GSL) and none of them was using
GMP. So i gathered a small library which uses GMP float type,
unfortunately in C++, i fell for the damned siren —hey, don't
blame me, GMP data class operators were so tempting! Besides, the
code is very C (c99), if you don't worry about what actually
happens when you write a '+' between two numbers, however (and of
course, new-delete couple). In fact, it was converted from c99
code with minimal modification. You need to link it with libgmp
and libgmp++, and other standard stuff libc, libm and libstdc++
released under GPL and not
LGPL. The name is chibi, because she gets on ねえーちゃん BLAS's
nerves (like Chibi-Usa), by doing something ねえーちゃん can't do
despite her tiny dimensions, for it's beyond the limits.
So, what can it do? Matrix operations: addition, subtraction, multiplication, transpose, computation of eigenvalues and eigenvectors of symmetric matrices (which uses von Neumann's algorithm). It can also convert lower triangle format (which i hear to be popular at CERN) matrices to raw matrices, vice and versa. What are you looking at? That's it guys, for now. I may add determinants, matrix inversion, and some combo functions such as "multiply the first matrix by a constant, add it to second, and store the result in third", etc. in the future. Expect soon. RSN :)

mkfs.xfswithout confirmation). What is worse is, I found out that the genious who wrote the code that runs
mkfs.xfsdecided to set data section options explicity, which made new
agcount16 (the default options result in 4 AGs) so some of my inodes and stuff were replaced by superblocks. So I desperately needed a tool that can recover from a formatted and damaged XFS filesystem. But well, there was none. So i digged up in the SGI's website, and found the holy document that saved me from the depths of agony :)
XFS Filesystem StructureAnd I got this quick-n-dirty code out of it in a few days, which saved almost everything from that crippled filesystem. It served well as "unformat" or BIG undelete for XFS :) Make sure to see the README first!
xfsr-20091207.tgzI have recently found this new utility,
xfs_irecover, which is a part of hxtools:
http://jengelh.medozas.de/projects/hxtools/This tool should be more reliable on healthy inodes and datablocks since it uses
xfs_db, but if you need flexibility and low-level control in filesystem operations (which is something you want, if your filesystem is damaged overall), you can switch back to
There're other projects hosted under GNU/Anime as well, see the full list here.
AGTHC is a unified frontend for various Japanese translators, transliterators, dictionaries and part-of-speech taggers. Since AGTH has no problems running under GNU/Linux with Wine, this script is a free alternative to ATLAS. You don't really need AGTH to use this program, though. See the project page for details:
Sadly, there's not much content in this department for now.
Aside from these, i have a blog (which appears to be down nowadays) —however, the update frequency can be compared to the average line-up frequency of nine planets :P
Aaaand, keeping up with the latest fashion, here's a screenshot of my desktop. Yup, unfortunately it's intel :/(and "KDE 98" version of my desktop)
