Schedule::Cron is a Perl module that provides a simple but complete cron-like scheduler. It can be used for periodically executing Perl subroutines. The philosophy behind Schedule::Cron is to call subroutines periodically from within one single Perl program instead of letting cron trigger several (possibly different) Perl scripts. Everything under one roof. Furthermore, Schedule::Cron provides a mechanism to create crontab entries dynamically, which isn't that easy with cron. It knows about all extensions (at least all extensions the author is aware of, i.e those of "Vixie" cron) for crontab entries like ranges including 'steps', specification of month and days of the week by name, or coexistence of lists and ranges in the same field. It even supports a bit more (like lists and ranges with symbolic names). It has existed since 1999 on CPAN and is successfully used in many projects.
CCI:U Open Course Labs is a Django-based Web application that interfaces cloud-computing infrastructure such as Amazon EC2 and NexR iCube Cloud. More backends may be added. It provides the access to cloud infrastructure in the form of "course labs" where course staff in an academy can manage the allocated computing resources and assignments easily. Course labs can also be used as course homepages.
XorCurses is a game based entirely on Xor by Astral Software. The original game was released around 1987 for the 8-bit home computers popular at the time. XorCurses attempts to faithfully recreate that game for Linux, but slightly ironically, uses ASCII characters instead of pixel based graphics (which even the 8-bit computers could manage). The idea of Xor is to roam around a series of mazes collecting masks. The first level is simply a matter of finding your way around, but the second level introduces fish and chickens which block your path or kill you if they hit you. From there on in, things get progressively tougher and really is a challenging and difficult puzzle game.
katimon is an unofficial ATI graphics card temperature monitor, fan regulator, and overclocking utility. It is a graphical front-end to the command-line aticonfig utility. Katimon monitors and controls supported ATI graphics cards. It can monitor temperature, fan speed, GPU speed and memory speed. It can automatically control fan speed by monitoring the temperature. It can also act as an overclocking utility for cards that support it. This utility only works with the proprietary fglrx driver.
Samuel is a game derived from guicheckers that allows you to play English draughts or American checkers. It features the ability to change the level of play from beginner to expert, load and save games, and edit the board position. It has a fairly strong engine written in C++ coupled to a PyGTK frontend GUI.
Graudit is a simple script and signature sets that allows you to find potential security flaws in source code using the GNU utility, grep. It's comparable to other static analysis applications like RATS, SWAAT, and flaw-finder while keeping the technical requirements to a minimum and being very flexible.
