gaim-blocky is a gaim plugin to block messages from certain contacts in a protocol-independent way.
Optionally, you can have an auto-reply message sent to blocked users whenever they try to bother you.
gaim-blocky is a gaim plugin which lets you block messages from certain contacts in a protocol-independent way. Its code is based heavily on gaim-bs by David Everly.
To block a user, all you have to do is append " " (three spaces) to their alias. Optionally you can have an auto-reply message sent to them whenever they try to bother you.
Enhancements:
- The ability to have messages from people who are not on your contact list blocked by default was added.

Javacelot project is a Java-based home automation utility for the Adicon Ocelot.
Javacelot is a Java utility for communicating with an Adicon Ocelot over the serial port. It uses Keane Jarvis RXTX utility for raw serial port I/O, Jakartas Log4J for logging, and Ant for building.
Javacelot mainly adds a friendly API for triggering and responding to X10, infrared, and other Ocelot signals.
Its not an application in itself, but a tool to facilitate the creation of Java-based home automation applications, especially heavily threaded Web-based applications.
Main features:
- Allows you to create and edit several Ocelot programs simultaneously.
- All configuration and source files are ordinary text files. Use your own text editors, versioning tools, scripts, or whatever.
- Built-in text editor with syntax highlighting and error navigation.
- New programming syntax similar to C# and Java, with support for multiple scopes, nested conditionals, aliases, and most other Ocelot features.
- Drag and drop of files for sharing between projects, or to reorder within a project.
- Built-in programming API allows you to write your own Ocelot-aware [java] applications.
- Generates a C-MAX compatible binary for each project.
- [RXTX] Upload programs directly to the Ocelot over the serial port, instead of using C-MAX.
- [RXTX] Send X10 commands
- [RXTX] Monitor X10, IR, and ASCII activity reported by the Ocelot.
- More to come!

Wmbattery displays the status of your laptops battery in a small icon. This includes if it is plugged in, if the battery is charging, how many minutes of battery life remain, battery life remaining (with both a percentage and a graph), and battery status (high - green, low - yellow, or critical - red).
Theres nothing in the program that makes it require WindowMaker, except maybe the look. It can be docked in WindowMaker or Aftersteps dock.
Wmbattery is based heavily on wmapm by Chris D. Faulhaber.
Enhancements:
- Improved icon layout. I crammed the same information into less space while making the icon more elegant and visually pleasing (IMHO).
- Easier to drag onto dock.
- It consumes a little less memory.
- Uses only 10 colors.
- ACPI support, including multiple battery support and battery charging completion countdown timer.
- Support for getting battery status from the sonypi driver instead of APM, for some Sony laptops that do not have apm support.
- Can make its own estimatess of time remaining or time until full charge, even if APM does not.

Nexuiz is a fast-paced, chaotic, and intense multiplayer first-person shooter game, focused on providing basic, old style deathmatch.

Nexuiz is extremely modder-friendly. Nexuiz is built on the power of the Darkplaces engine, which is a heavily modified version of the original Quake.

Darkplaces features realtime lighting and stencil shadows, bumpmapping, gloss, bloom, and totally rewritten network code that supports up to 64 players on a single server.

Netkit has been conceived for doing networking experiments at low cost. Several fully fledged routers, switches, and computers can be easily "created" and interconnected on a single pc.
Such networking equipments are virtual but can be operated with many of the features of the real ones.
Netkit exploits open source software (mostly licensed under GPL) and is heavily based on User Mode Linux (UML). The purpose of our efforts is to solve many of the difficulties and technicalities that a user could have in using UML for networking. Namely, we offer to the users an easy to use and to install package.
Enhancements:
- Improved checks for the presence of terminal emulator applications (both in check_configuration.sh and in the Netkit scripts).
- Fixed a bug inside vcrash and vclean (wrong signal spec when killing processes broke both vcrash and vclean).
- Placed a workaround to avoid early hangs of the port-helper process when booting virtual machines.
- Removed some minor warnings issued by vstart and vclean.
- Fixed a small bug in the output of vlist.

GNOME Mplayer project is a simple GUI frontend for Mplayer.

It is based heavily on the mplayerplug-in source code and can basically be seen as a standalone version of that. Currently it is a test bed for new methods of operation for mplayerplug-in and so it may be broken or lacking many features. I use it as my default viewer for media on my personal machine.

To set GNOME Mplayer as the default player for mms and rtsp protocols in Mozilla/Firefox add this to your prefs.js file

user_pref("network.protocol-handler.app.mms", "/usr/bin/gnome-mplayer");
user_pref("network.protocol-handler.app.rtsp", "/usr/bin/gnome-mplayer");

Or open the "about:config" location and create new string settings with the above values.

Understanding computer networks without performing practical experiments is really difficult, not to say it is almost impossible. Unfortunately, setting up a networking lab can be very expensive.

Netkit has been conceived as an environment for setting up and performing networking experiments at low cost and with little effort. It allows to "create" several virtual network devices (full-fledged routers, switches, computers, etc.) that can be easily interconnected in order to form a network on a single PC. Networking equipments are virtual but feature many of the characteristics of the real ones, including the configuration interface.

Netkit exploits open source software (mostly licensed under GPL) and is heavily based on the User Mode Linux (UML) variant of the linux kernel. The purpose of this project is to solve many of the difficulties and technicalities that a user could have in using UML for networking. We offer the users an easy-to-use-and-install package, which at the same time implements effective network emulation. Further, we provide a corpus of teaching material that can be used for courses at different levels.

PDFKreator is an easy to use KDE tool for creating PDF documents out of a bunch of image files. It heavily uses ImageMagicks convert tool, tiff2ps and ps2pdf.
