Free general purpose software for linux

GNU Radio is a collection of software that when combined with minimal hardware, allows the construction of radios where the actual waveforms transmitted and received are defined by software. What this means is that it turns the digital modulation schemes used in todays high performance wireless devices into software problems.
What is a Software Defined Radio?
Joe Mitola says, "A software radio is a radio whose channel modulation waveforms are defined in software. That is, waveforms are generated as sampled digital signals, converted from digital to analog via a wideband DAC and then possibly upconverted from IF to RF. The receiver, similarly, employs a wideband Analog to Digital Converter (ADC) that captures all of the channels of the software radio node. The receiver then extracts, downconverts and demodulates the channel waveform using software on a general purpose processor."
For our purposes, on the receive side, the idea is to get a wide band ADC as close to the antenna as is convenient, get the samples into something we can program, and then grind on them in software.
Enhancements:
- GNU Radio 2.6 includes sending and receiving data at up to 1Mbit/sec using GMSK. - Theres also support for the new USRP Flex 400 transceiver daughterboards.
- Handling of all daughterboards has been unified, so most apps will work without modification on any of them. For those of you interested in wireless networking, see especially gnuradio-examples/python/gmsk2. Weve got a framework in place to allow you to build and experiment with your own MACs. 2.6 includes the "null MAC". A carrier sense MAC is the next logical step.

Test::Parser is a collection of parsers for different test output file formats. These parse the data into a general purpose data structure that can then be used to create reports, do post-processing analysis, etc.

Test-Parser can also export tests in SpikeSources TRPI test description XML language.

Installation:
To install the script and man pages in the standard areas, give the sequence of commands
$ perl Makefile.PL
$ make
$ make test
$ make install # you probably need to do this step as superuser
If you want to install the script in your own private space, use
$ perl Makefile.PL PREFIX=/home/joeuser
INSTALLMAN1DIR=/home/joeuser/man/man1
INSTALLMAN3DIR=/home/joeuser/man/man3
$ make
$ make test
$ make install # can do this step as joeuser
Note that `make test` does nothing interesting.
Enhancements:
- This release improves the LTP parser and adds a parse_ltp script that prints a tabular summary of the PASS/FAILs of test cases.

Frugalware is general purpose linux distribution, designed for intermediate users (who are not afraid of text mode).
Frugalware Developer Team is pleased to announce the immediate availability of Frugalware 0.3-i686, our third stable release.
Whats New in 0.6 Stable Release:
- The Frugalware Developer Team is pleased to announce the immediate availability of Frugalware 0.6, our sixth stable release. Here are the most important changes since 0.5: up-to-date base system: glibc 2.5, binutils 2.17.50.0.6 with DT_GNU_HASH support, DBUS 1.0 and Python 2.5; up-to-date desktop packages: KDE 3.5.6, Xfce 4.4, Beryl 0.2.0, OpenOffice.org 2.1, Firefox 2.0.0.2 and GNOME 2.18; all installed-by-default packages using Java are now built using gcj/ecj, the original binary javac is only provided as an alternate compiler; setup: speed improvements, support for more custom action, TFTP installs and USB sticks are now supported; full support for Xgl/Beryl in KDE.

Unlimited Simulator project is a general purpose simulator.
Unlimited Simulator is not a game. Its a basis to create whatever simulations you want, from games to scientific simulations.
You only have to worry about physics, controls and how the world looks like. It can be at the same time a car simulator, a spaceships war game, or a scientific simulation.
While you can do these things on their own, Unlimited Simulator provides the ability to do all three at once. It allows interaction of completely different kinds of clients, thus achieving unprecedent realism and complexity.
Main features:
- multiplayer: many players by internet or two in your computer;
- create your own vehicles, tracks, terrains, sounds, objects;
- vehicles may have their own physical simulation functions, and interact with the game, creating new objects, destroying others. They can fly or float or move underwater; they can be animals, or surrealistic creations. You create.
- track can contain structures as loops, bridges, banked curves, and anything you can do with polygons;
- creating a track can be done DRAWING on the terrain (not implemented yet);
- objects can be animated and intelligent!
- everything is modular: this means almost all the stuff is plugable! No need to recompile the code;
- last, but not least: GPLed!
Enhancements:
- big debugging in ulengine/primitives.c. Several allocation problems solved.
- review of network code: structs separated in a new header, shared/net.h, and other improvements in code itself.
- review of client plugin format (what functions, names, etc).
- wrappers for the not-so-standard standard C variable types in config.h.
- cosmetic changes in some places, specially ulengine.h.
- BIG debugging in ulengine/project.c and ulengine/graphic.c. Only a billion or so bugs left.
- improved ulengine/demo.c; tests now include graphic functions.
- fixed two small bugs in drawHLine due to rounding.
- added a new projection system. Not tested yet.
- graphics test phase started: drawPixel, drawHLine, drawLine, drawFlatTri and drawShadedTri are working.
- modified POLY_UL structure: SCREENP_UL *projected field was deleted. This field is really unecessary, and deleting it saves 2*sizeof(int) bytes for each vertex. Projections are not individually saved anymore (why should they be after all?). See ulengine/project.c:projectP() to see how projected points are handled.
- added ulengine/image.c, to handle image operations.
- added ulengine/effects.c.
- textures support implemented.
- several small optimizations in ulengine/graphic.c.
- work in the server communications system.
