Libmmoss enables the Linux version of Netscape Navigator/Communicator to play sounds from Java applets. It is a replacement for Netscape's implementation of (the Java class) sun.audio.AudioDevice (including some JRI native C code). It should work with either the OSS or ALSA sound drivers. The latest version will also work with EsounD.
CIPE (Crypto IP Encapsulation) is an ongoing project to build encrypting IP routers. The protocol used is as lightweight as possible. It is designed for passing encrypted packets between prearranged routers in the form of UDP packets. This is not as flexible as IPSEC but it is enough for the original intended purpose: securely connecting subnets over an insecure transit network.
Genius is an arbitrary precision integer and multiple precision floating point calculator. It includes its own programming language similar in some aspects to C, bc, or Pascal. It can deal with rational numbers and complex numbers. It has matrix support as well. It uses the gmp library so it is very fast for calculations of large numbers. It has a command line and a GNOME interface. The GNOME interface supports plotting functions and 3D surfaces.
SoundTracker is a pattern-oriented music editor (similar to the DOS program 'FastTracker'). Samples are lined up on tracks and patterns which are then arranged to a song. Supported module formats are XM and MOD; the player code is the one from OpenCP. A basic sample recorder and editor is also included.
Eznet makes setting up PPP for Linux easy. Just enter the name of your ISP, a phone number to dial, the login name, the password and the TTY and eznet takes care of the rest. There are no chat scripts to write, nor any pppd configuration files to fuss over. Eznet handles multiple ISPs and can dialup any of them with a single simple command. It also supports dial-on-demand using either kerneld or diald.
Xoscope (or oscope) is a digital oscilloscope using input from a sound card or EsounD and/or a ProbeScope/osziFOX. Its features include 8 simultaneous signal displays, 1 us/div to 2 s/div time scale, built-in and external math functions including inverse, sum, diff, avg, xy, and FFT, 23 memory buffers, 5 automatic measurements, and file save/load.
