Software:

• Kernel patches for Linux.
• SMB Gateway. This is a web frontend to access SMB (a.k.a. Windoze network) servers.
• Apt-mirror is a cgi script that acts as a proxy for apt-get. It saves every file that was retrieved to a local directory structure. This can save a lot of bandwidth if you have multiple Debian machines behind a slow Internet link.
• Soepkip The Next Generation.
  My mp3/wav/lpac/ogg-vorbis music playing daemon, with very nice (and fast) web interface (using mysql and mod_perl).
• Cdrplay.
  Plays raw audio data to /dev/dsp. With special features for SoepkipTNG.
• Resample.
  Simple program for sample rate and mono->stereo conversion. No filtering, just linear interpolation.
• Ogg2raw.
  Reads Ogg-Vorbis files and plays them to stdout.
• Lpac2raw.
  Reads LPAC files and plays them to stdout.
• Isoextract efficiently copies all files from a cd (minimizing the number of seeks).
• Patches/add-ons for qmail/ezmlm
• Run c source files as scripts!
