Free light 1.0 software for linux

Tremulous for Quake 3 Arena is an open source modification that blends a team based FPS with elements of an RTS. Players can choose from 2 unique races, aliens and humans. Players on both teams are able to build working structures in-game like an RTS.
These structures provide many functions, the most important being spawning. The designated builders must ensure there are spawn structures or other players will not be able to rejoin the game after death. Other structures provide automated base defense (to some degree), healing functions and much more...
Player advancement is different depending on which team you are on. As a human, players are rewarded with credits for each alien kill. These credits may be used to purchase new weapons and upgrades from the "Armoury". The alien team advances quite differently. Upon killing a human foe, the alien is able to evolve into a new class. The more kills gained the more powerful the classes available.
The overall objective behind Tremulous is to eliminate the opposing team. This is achieved by not only killing the opposing players but also removing their ability to respawn by destroying their spawn structures.
Main features:
- New flexible particle system for Q3 - can create smoke, water, fire easily in Q3 maps.

OpticalRayTracer is a free Linux utility that analyzes systems of lenses, it is Xwindows GUI-based.

It uses optical principles and a virtual optical bench to predict the behavior of many kinds of ordinary and exotic lens types. OpticalRayTracer includes an advanced, easy-to-use interface that allows the user to rearrange the optical configuration by simply dragging lenses around using the mouse.

OpticalRayTracer fully analyzes lens optical properties, incuding refraction and dispersion. The dispersion display uses color-coded light beams, as shown above, to simplify interpretation of the results.

Educators take note: OpticalRayTracer has significant educational potential in the teaching of basic optical principles, and it has some entertaining and game-like behaviors to hold the students attention.

OpticalRayTracer includes a detailed tutorial/help file to assist the user in getting started in this interesting activity.

Installation:

Put it in any convenient location.
$ tar -xjf raytracer.tar.bz2
$ cd raytracer.dist
$ ./auto_install.sh
If you dont want the automatic installation or you want to fine-tune the process, instead of running "auto_install.sh", after the unpacking step above, do this:
$ make -f Makefile.cvs dist
$ ./configure
$ make
$ sudo make install
Obviously you may want to modify some of these steps to suit your platform.

SCRAP project is capable of working with any video4linux compatible device, supporring all of its documented features.

It can grab frames from multiple inputs of a single device and also support working with multiple capture boards at the same time, giving user the advantage of a low-cost recording system.

It has a very reliable motion detection system, recording only when movement happens and ignoring the rest, including light changes. So, in a tipical 24h recording cycle, you will have only a few hours of recorded video.

Videos are recorded using XviDs MPEG-4 compression, witch is one of the best video codecs today. The generated AVIs should be playable on AVI+MPEG4 capable video player (all modern video players are).

There is also a recording archive management system, with alow the user keep archived only the recent recordings, erasing the old ones. User can set to erase recordings older than a number of days, or set a maximum disk usage.

Although SCRAP is a console application, it is full featured. It is intented to be run as a daemon, in the background, letting SCRAP doing the recording job without other systems users even notice it is running.

MoBlock is a linux console application that blocks connections from/to hosts listed in a file in peerguardian format (guarding.p2p and p2p.p2b) or ipfilter.dat files.

MoBlock project uses iptables ipqueue userspace library and it is very light in resource usage.

Gtkedit1 is a notepad clone based on GTK+.
Gtkedit1 is a simple editor, written using the GTK+ 1.2 toolkit. It aims to be (in that order) light, useful and simple (source code-wise).
Main features:
- Binary weight less that 30 KB.
- Takes less than half a second to start in the development machine.
- Has nearly all the features of Windows 2000 Notepad (only printing and help are missing).
- The C source code is a single file, about 1400 lines long. No need to use a configure script or even a makefile.
What? another editor? Dont we have enough of them already?
Well, yes, indeed. There are quite a lot of different - and not so different - editors one can download from the Internet. Anyway...
1. I wanted a simple project to try GUI programming in Unix.
2. I have an old machine (Pentium 166 MHz, 32 MB RAM) with Slackware Linux 9.0. 3. This machine runs Xfce 3.8, based on GTK+ 1.2.
Theres no decent GUI editor for this machine. All are too slow, too bloated or too ugly.
OK, In fact I did found an editor that works fine. Its called gnotepad+, but it too takes too long to load (about 2 seconds) in this old machine. Theres plenty of room for improvements here, I thought.
And so gtkedit begun. I only wanted the most basic editing features: cut, copy, paste, basic undo/redo... nothing fancy. The obvious model to copy was, of course, Notepad.
Usage:
gtkedit is very simple to use. It understands the basic common shortcut keys, like < Ctrl >C for copy. You will find them listed next to each menu item.
Very basic undo/redo capabilities are provided, because the editor can only undo the very last text insertion or removal.
You can find and replace text, and there is a menu option that will allow you to quickly go to any particular line, which is handy if one is writting a program and wants locate an error line.
Finally, you can change the font used for text display, or toggle the wrapping of long lines. These settings are lost when the program closes, though.
