QtOIDUA is a graphical user interface for OIDUA for Linux and Mac OS X written in C++ using Qt. It is completely free and open source, and is licensed under the GNU GPL.
QtOIDUA supports all the features of OIDUA and makes it easy to create fields, add directories, choose colors, and set options. QtOIDUA also allows you to save list configuration files, so you can easily recreate any previously created list.
OIDUA is an Audiolist clone by Sylvester Johansson and Mattias Paivarinta. Its purpose is to generate lists of audio files based on their location in your directory tree.
Enhancements:
- Added options that allow the user to specify whether they want a new file, the previously opened file, or a specific file to be loaded on startup.
- Fixed a bug that caused options to be enabled/disabled improperly when the output.db option was checked while OIDUA was downgraded to a version that didnt support it.
- Slightly resized the icons image so it better fits in both Linux and OS X.
- Icon now displayed in Linux if supported by the users window manager.
- No longer necessary to manually copy the icon into the application bundle and edit the Info.plist file when compiling in OS X.
- Added logo to the About window.
- Various code changes and cleanups.

pyglplot is a program to 3D-plot mathematical functions and datafiles. It is written as a module for python and as such features the full power and flexibility of the python programming language.
Main features:
Data Sources
- Plot python functions
- Plot python dictionaries containing the coordinates of the points and their position in the grid
- Plot plain datafiles as understood for example by gnuplot
Graphics
- Can make 3D plots of surfaces in normal or parametric mode
- Support coordinate transforms, i.e. can make e.g. polar plots
- Support for pm3d-style coloring of the surface
- Support for wireframe plotting atop of the surface
- Support for transparency: translucent plots
- Support for different types of fog and arbitrary background colors
- Support for dynamic light and specular reflexes etc.
- Use either perspective projection or parallel projection
- Save the rendered plots as portable network graphics (.png)
- Adjust all graphics parameters via dialog windows
Platforms
- This program is developed and tested on Max OS X 10.4 on powerpc with fink and Debian GNU/Linux on i386. It should compile and run everywhere where its prerequisites and requisites thereof are available. These are gtkglext-1.0 and gthread-2.0. Some minimum versions of the libriaries must be met, unfortunately, the gtk+-2.2 packages provided by fink for Mac OS X 10.3 are not sufficient -- perhaps I will port it there.

Teddy is a tabular editor and display for XML files. It presents the structure and content of XML files in a way that is both visually pleasing and easy to use. It is available free, under the GNU public license, for Mac OS X and Linux.
If you have Qt for Windows it should build and run fine for it, but it has not been tested on that operating system.
Enhancements:
- Ability to open currently opened file in external text editor.
- Linux RPM installs application icon and start menu item in KDE.
- Save no longer forces scroll position to the top.
- Single line cell styles now correctly dimensioned.

Klep is Yet Another virtual flashcard program, which helps in putting information into ones short term memory.
Klep has many features not commonly found in virtual flashcard programs, including export to memaid so that material learned in Klep can be retained in the long term, support for images, support for multiple choice questions, and a bunch more.
Klep uses wxWidgets, so it should theoretically work in UNIX-likes (GNU/Linux, Mac OS X, freeBSD, etc), Windows, OS/2, and others, although binaries are currently only available for GNU/Linux and Windows.
Enhancements:
- Some bugs related to images were fixed.

dsync is a tool for merging or synchronizing contents of two directories, or just for backups.
dsync project is written in Perl. dsync is inspired by Dan Kogais psync.
I sought something similar to (but more robust than!) the legacy PowerMerge programs available some years ago for classic releases of Mac OS. Dan Kogais nifty psync and supporting MacOSX::File modules seemed like a great start.
Having some time during the lull of the holiday season, I cobbled together Dsync. With Dsync, I attempted to capture the feature set of PowerMerge with the foundation of psync and a few ideas for improvement.
This is an early release. I use it on my systems with some degree of success, but the tool is far from well-tested, predictable, or reliable. Please treat it as development-grade software and help me improve it with your feedback.
While Dsyncs current focus aims exclusively at Mac OS X and its underlying idiosynchracies, I expect that it would be trivial to modify Dsync to work under any unix-like OS.
Installation:
Copy the program to wherever it is easily accessible:
$ cp dsync /usr/local/bin/
Make sure the executable bit is set:
$ ls -l /usr/local/bin/dsync
-rwxr-xr-x 1 root root 24841 Dec 25 13:54 /usr/local/bin/dsync
if not, then set it:
$ chmod +x /usr/local/bin/dsync
If you have Perl installed elsewhere than /usr/bin, then create a symbolic link:
$ cd /usr/bin
$ ln -s /usr/local/bin/perl
[or wherever you keep Perl]
You will also need MacOSX::File by Dan Kogai:
< http://search.cpan.org/dist/MacOSX-File/ >
To get started, take a look at dsync.html included with this distribution or type:
$ perlpod /usr/local/bin/dsync
[or wherever you stashed dsync]
Enhancements:
- Added an option for lax synchronization to foreign file systems.

XDaliClock is a digital clock for Mac OS X, the X Window System, and PalmOS devices. When a digit changes, it "melts" into its new shape with color-cycling.
Dali Clock is a digital clock. When a digit changes, it "melts" into its new shape. The date is displayed when the mouse is pressed. The window can be made transparent, and can do funky psychedelic color cycling.
It is available for X11, MacOS X, and PalmOS. There is no Windows version, so dont ask.
It can display in 12 or 24 hour modes, and displays the date when a mouse button is held down. It has two large fonts built into it, but it can animate most other fonts that contain all of the digits. It can also do some funky psychedelic colormap cycling, and can use overlay planes or the `shape extension so that the window is transparent.
In the default configuration, this program is very network-intensive. If it seems sluggish, try the "-memory high" option (see the man page). It will take a little longer to start up, but will then go easy on the bandwidth.
This program was inspired by the Alto/Macintosh programs of the same name, written by Steve Capps some time in the early eighties. This implementation is mine, and if youre looking for another reason to hate the X Windows ``feature of network-transparent graphics, well here you go.
Enhancements:
- The OS X version has a prettier preferences panel
- The PalmOS version has smoother morphing, a bigger "seconds only" font, and does color cycling on color devices.
- The X11 version has smoother morphing, better color-cycling contrast, and three more (larger) built-in fonts.
