Otetsudaiqt is a bonsai collection management software for *nix systems, it helps you to manage your trees, your pots and your pictures.
Main features:
- It keeps a list of your trees with their characteristics. For each tree, you can apply "events" which will be remembered or add pictures. Pictures can be resized and moved to a repository while the original may be saved in another place if you wish. At any time, you can get the history of a tree which presents in one page all the characteristics of the tree and list in chronological order all the pictures or events applied to it.
- It can keep a list of your pots if you wish. Free pots can be choosen when rempotting a tree, can have pictures and the history of each pot can be obtained.
- Successfull compilation and use on Mac Os X has been reported! UPDATE : A (french only) installer for Mac Os is now available.
- Dont be fooled by the 0.1 version, it is already quite usable, and I do use it !

Gabber 2 is the next generation of Gabber: The Gnome Jabber Client. Gabber 2 is a Jabber client written in C++ using Gtkmm2 which is currently available for Linux and Mac OS X (under X11).

ClanLib is a cross platform C++ framework. Essentially the library offers a series of different functionality under a streamlined API. Its primary focus is on games, although its not limited for that usage only.
Main features:
- Supports Microsoft Windows, Linux and Mac OS X
- Basic cross platform runtime (threading, file I/O, etc.)
- Template based C++ signal library (type-safe callbacks / delegates)
- Integrated resource management
- Sound mixer supporting wav, mikmod formats (mod/s3m/xm/..), ogg vorbis
- XML/DOM support
- High-level 2D graphics API supporting OpenGL and SDL as render targets
- Batch rendering engine giving maximum performance when rendering 2D with OpenGL
- 2D collision detection
- 2D sprite animation support
- Highly customizable GUI framework
- Network library with low-level to high-level interfaces
- Cross platform OpenGL 2.0 wrapper (target Microsoft Windows, Linux and Mac OS X at the same time)
- Full reference manual and many overviews which goes in detail on various topics in clanlib
Framework libraries generally support the same things that can be gained by combining other specialized libraries. However, a good framework will combine and simplify the usage through a common set of conventions. The primary goal of ClanLib is to aid developers to rapidly create games and other applications.

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.
