Free purposes for writing software for linux

Ghost for Linux project is a hard disk and partition imaging and cloning tool similar to "Norton Ghost" and by Symantec.
The created images are optionally compressed, and they can be stored on a local hard drive or transferred to an anonymous FTP server.
A drive can be cloned using the "ClicknClone" function. g4l supports file splitting if the local filesystem does not support writing files >2GB. The included kernel supports ATA, serial-ATA, and SCSI drives.
Common network cards are supported. It is packaged as a bootable CD image with an ncurses GUI for easy use.
Enhancements:
- This release adds new kernels and syslinux, plus other support program options.
- It adds ntfs-3g to support writing to ntfs partitions for the local backup images and adds ntfsclone backups to local drives or partitions.
- Users can now copy the files from the CD image to a flash drive that has been made bootable, and it will then work from flash.

Spoon is a Java program processor that fully supports Java 5. The project provides a complete and fine-grained Java metamodel where any program element (classes, methods, fields, statements, expressions, etc.) can be accessed both for reading and modification.
It can be used for validation purposes, to ensure that your programs respect some programming conventions or guidelines, or for program transformation, by using a pure Java template engine. It provides an Eclipse plugin (SpoonJDT) that allows for tight integration of Spoon within the Eclipse environment.
With SpoonJDT, a set of validations and transformations packaged as a Spoonlet can occur on the fly, and the reports are well-integrated into the Eclipse JDT.
Enhancements:
- This version includes a lot of bugfixes and new features.
- In particular, Spoon now adjusts the line numbers of the generated bytecode so that they match the original source code.
- So, debugging spooned programs is finally as simple as debugging regular programs.

Jurpe is a Role Playing Engine.

JURPE (Java Universal Role Playing Engine) is a Java API to support the writing of new computer RPG games based on a skill based, three dice RPG system. It comes with a full featured game demo of a medieval warrior crawling into a monster filled dungeon.

GNOME Mastermind is a Mastermind clone for GNOME Desktop.

GNOME Mastermind is a simple mastermind-like game that ive written mainly for fun and with learning purposes in spare time. Now it became quite stable and i decided to distribute it. Try it and give me some feedback.

Python library for PS3 (Sony Playstation 3) game development under Linux. Includes: rendering to the PS3 frame buffer on a per pixel basis or with blittable objects (solid, masked or alpha blended), support for PS3 controllers and integration with PIL.
As you may know, Ive been writing my PS3 stuff with a view to building up a library suitable for writing games and as I thought about it more the idea of using a scripting language for the game seemed the most logical way forward. I plumped on python as Id used it before for a couple of small jobs and it seemed like a nice language with a lot of support. Plus, it has the advantage of being pre-installed on most Linux distributions and very easy to extend, and so the PS3 library for python was born...
Brief bullet points of the current build:
Support for the PS3 frame buffer on a per pixel basis
Support for blittable objects (solid, masked or alpha blended)
Support for the PS3 controllers
Easy integration with PIL for image manipulation and text rendering
A proof-of-concept breakout game
After about a day and a half development, the core of the library was in place but in a not very visible way. It seemed that the only way I could actually demonstrate this to all be good stuff is by writing a quick game. And breakout is one of the simplest, so I spent another day writing that. Its important to have a good demo on release... So, Ill settle for this half-hearted attempt at a breakout game whose main redeeming feature is that it has alpha transparency on all the blocks!
Just to whet your interest, heres an example of how easy the code can be (taken directly from the test.py file):
image = Blittable(Image.open("miglu.jpg"))
for count in xrange(screen.height-image.height):
screen.clear()
screen.blit(image, (count,count) )
screen.flip()
screen.wait()
Enhancements:
- Adds support for image blitting with the SPUs.
- Currently, using 4 SPUs the alpha blended breakout demo runs at 30fps at 720p.
