BRL-CAD is a powerful constructive solid geometry solid modeling system that includes an interactive geometry editor, ray-tracing support for rendering and geometric analysis, path-tracing for realistic image synthesis, network distributed framebuffer support, and image and signal-processing tools.
Secure Syslog is a cryptographically secure system logging tool for UNIX systems. Designed to replace the syslog daemon, ssyslog implements a cryptographic protocol called PEO-1 that allows the remote auditing of system logs. Auditing remains possible even if an intruder gains superuser privileges in the system, the protocol guarantees that the information logged before and during the intrusion process cannot be modified without the auditor (on a remote, trusted host) noticing.
dirgroup is a Perl script for merging the contents of a directory, /etc/group.d, into the file /etc/group. Storing group information in a directory allows users other than root to own and manage Unix groups. This minor change to Unix permission semantics provides many of the advantages of much more complex ACL systems.
Moosic is a music player that focuses on easy playlist management. It consists of a server process that maintains a queue of music files to play and a client program which sends commands to the server. The server continually runs through its playlist, popping items off the top of the list and playing each with an external program. The client is a simple command-line utility which allows you to perform powerful operations upon the server's queue, including the addition of whole directory trees, automatic shuffling, and item removal according to regular expressions. The server comes configured to play MP3, Ogg, MIDI, MOD, and WAV files.
FCFS RWLock is a first-come first-served readers/writers lock for POSIX threads. FCFS means that the first thread to request control of the lock will gain it, based on the constraints of a readers/writers lock. FCFS RWLock is well documented and commented, so it can easily be used as a reference implementation.
ModPlugLine is a module player that uses ModPlug for mod rendering. It runs in the console (through curses) and uses the OSS for output. It supports all modules supported by ModPlug (S3M, IT, XM, MOD, UMX, etc.) except for compressed modules (S3Z, RAR, ZIP, etc.). ModPlugLine features great sound because it uses micro volume ramping (noise reduction) and polyphase oversampling. It also has an XBass feature to boost low-frequency bands.
Monica is a monitor calibration tool using the FLTK library. It works as frontend to xgamma to alter the gamma correction for XFree86 or Xorg. The black point, gray, and color blocks help to find usable settings for a target of 2.2 gamma, the Web, and sRGB standard. FLTK libs are not needed for the binary.
MP3DB2 is a collection of bash scripts for keeping track of large MP3 collections. It will retrieve song information from the filenames and ID3 tags of a directory or CD of MP3s and store them in a local database. It then allows you to search any of the fields, generate a master listing of all your complete albums, see the size of your entire collection, and more.
