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.
FIDOGATE is a Fido-Internet gateway and a Fido tosser. The gateway converts between the worlds of Fido NetMail/EchoMail (or FTNs, Fido Technology Networks in general) and the UNIX mail/news system. FIDOGATE will convert Fido mail packets to RFC822/1036-style messages and vice versa.
The Regex Coach is a graphical application for Linux and Windows which can be used to experiment with (Perl-compatible) regular expressions interactively. It shows whether a regular expression matches a particular target string, and can also show which parts of the target string correspond to captured register groups or to arbitrary parts of the regular expression. It can "walk" through the target string one match at a time and simulate Perl's split and s/// (substitution) operators. It tries to describe the regular expression in plain English. It can show a graphical representation of the regular expression's parse tree. It can single-step through the matching process as performed by the regex engine. Everything happens in "real time" (i.e., as soon as you make a change somewhere in the application all other parts are instantly updated).
Clementine is a modern music player and library organizer. It is inspired by Amarok 1.4, focusing on a fast and easy-to-use interface for searching and playing your music. You can search and play your local music library, and listen to Internet radio from Last.fm, SomaFM, and Magnatune. It has tabbed playlists, the ability to import and export M3U, XSPF, PLS, and ASX, visualizations from projectM, the ability to transcode music into MP3, Ogg Vorbis, Ogg Speex, FLAC, or AAC, the ability to edit tags on MP3 and Ogg files, organize your music, and download missing album cover art from Last.fm. It has native desktop notifications on Linux (libnotify) and Mac OS X (Growl), as well as remote control using a Wii Remote, MPRIS, or the command line. It can copy music to your iPod, iPhone, MTP, or mass-storage USB player. It has a queue manager.
YAJL (Yet Another JSON Library) is a small event-driven (SAX-style) JSON parser written in ANSI C, and a small validating JSON generator. It's highly portable, data representation independent, fast, generates verbose error messages including context of where the error occurs in the input text, can parse JSON data incrementally off a stream, and is tiny.
Multiplication Station will teach your child to add, subtract, and multiply. It is a multi-user application with a simple admin interface. All parameters are configurable, like grid size and the fonts and colors of number ranges. A countdown timer is used to keep the player's attention focused. A list of high scores is maintained.
