Free stable supplies software for linux

KSpline is a three parts library which supplies spline functions.
The library contains three parts:
A spline class. This class is invisible, it is used to store the coords and calculates the spline polynoms. Theoretical it can be used outside of KDE.
A visual Editor. This editor requires an initialisized spline class and works as an interface to this spline. Nearly all spline functions can be adjusted with this editor.
A demo program. This program creates two splines. They can be modified either manually (directy calls to the spline functions) or visuell with the editor.
System requirements:
- V 0.31 : KDE 3.0x (not tested with KDE 3.1x)
- qt 3 or newer

gtkcdlabel is a GUI frontend to cdlabelgen which is a program that can generate a variety of CD tray covers. The code is came from the idea of gcombust and gcdlabelgen.
Since the last release (0.7.7) Ive pretty much revamped the UI so that logically close UI elements are grouped together - I think its neater and makes navigation easier and faster - but Im no HIG expert.
The latest version (1.0pre1) supports all options of the latest version of cdlabelgen and also has several UI enhancements. You can now also use image formats other than EPS. If you have the program convert from the ImageMagick suite then any format it can handle can be used by gtkcdlabel. All thats left is bugfixes
Sebastian also set up the gtkcdlabel CVS repository so you can now acces it via anonymous CVS.
The versions from 0.7.0 upwards use GTK2 and as a result of the port Im no longer supporting the GTK1 version (i.e. versions before 0.7.0) though the last stable tarballs and RPMs can still be obtained here
Main features:
- Ported to GTK2
- Supports all of the options in cdlabelgen 2.6
- You can supply images of any format that ImageMagic can handle and EPS conversion is carried out on the fly
- Handles UTF8 and locales though no translations currently exist
- Doesnt require libcdaudio to access the CD drive or access freedb.freedb.org
- Itll process the ID3 tags on an MP3 CD
