Friend to Friend (F2F) Computing is a new paradigm for distributed computing, merging ideas from peer-to-peer, High Performance Computing, and social networks in instant messaging. It is also middleware in Java on top of the multi-protocol instant messenger SIP communicator. On top of this middleware you can write simple distributed programs using either a pure object-oriented approach or an MPI interface. You can easily set up a spontaneous desktop grid with your instant messaging buddies and share your computational power with your friends.
Based on ircu, Nefarious has features from various IRCds (Asuka, Bahamut, UnrealIRCd, and UltimateIRCd) with the intent of adding needed features to ircu without becoming too bloated or subject to anti-user behaviors. Most features can be activated or deactivated in the config file. Nefarious includes optional support for RBL-based blocking or marking, fakehosts, accounts, login-on-connect, half-ops, ban exceptions, mIRC color filtering chan-mode, network-wide bans (g-lines), and much more.

It is useful directly as-is, and with simple shell aliases can make a highly efficient system to do exactly what you want. It is perfectly capable of being your only client for microblogging. It can also be used in an automated way, via cron(1), or it can even integrate with your email system.
Chiron was written to demonstrate that you could embed special tokens in an infobots fact file so that recalling/matching a fact causes novel/interesting and hopefully useful behaviour. The 'tokens' gradually gained functionality, and now the factoids themselves are fully programmable. A tracing feature is used to automatically follow instructions, generate the code, and then learn it as a fact. There are many other features, including a hooking system for plugging multiple backend engines in to process what it sees, etc. The current problem with the program is the lack of documentation.
