cerberus is a modular and robust network operator and drone monitoring service designed to protect IRC networks from common threats that plague the community. It uses a BIND9-style configuration file with a mix of Perl syntax. It includes a map module that displays a server map along with basic information, stats/protocol for core protocol support, sql, an interface to DBI, modcontrol for controlling modules in use via IRC, login, operlist for displaying a list of all operators on the network, and more. It was designed for use with pure TS6 networks such as ircd-ratbox and ircd-hybrid.
PulkoCMS is a small and lightweight CMS. Instead of using a database for storing your pages, it relies on the standard Unix filesystem features. With fewer than 500 lines of code, it is easy to customize and alter for your own needs. It generates valid XHTML pages. It features a shoutbox, comments on all articles, categories (a 2-level system), hidden pages, easy customization of the appearance via CSS, and a simple photo gallery. It can send you notifications through XMPP/Jabber when someone posts a comment on your Website.
x11vis is a visual and interactive tool for debugging X11 clients. Unlike other tools such as xtrace, it displays human readable IDs on all requests, no matter at which point in time the information becomes available. To help you cope with large amounts of data, it displays only the most important information by default, automatically folds sequences of boring requests, allows you to filter by packet type or client, and provides markers for navigation. Instead of assigning a number to each connection, it displays the command line with which that client was started.
mysqlblasy is a Perl script for automating MySQL database backups. It uses "mysqldump" for dumping mysql databases to the files sytem. It was written with automated usage in mind. For example, it is silent during operation, and only produces noise on errors/problems. It rotates backups automatically to prevent the backup disk from getting full when the administrator is on vacation (or is lazy).
While the OSS community converges to Git, with the Python bunch branching to Mercurial, the typical workplace is stuck with Subversion. The author's DVCS of choice is Fossil. These are all fine projects, with their own pros and cons, but what you usually want is just a tool to store your code tree snapshot in a safe place. They can all do that, but their language differs a tiny bit. repo brings them all down to the common root. It works by detecting which VCS are you using right now and calling that, applying necessary subcommand translation if needed.
