Free internet and intranet software for linux

Internet Storm Center is a clone of the simple little Windows Konfabulator ISCTracker widget by Bob Rudis. It puts a little coloured globe on your desktop, with the colour of the land corresponding to the current level of Internet Storm Tracker.

Clicking on the globe takes you directly to isc.sans.org.

ALTSE is an alternative search engine technology.

It can index up to a couple million Web sites.

A search engine is a program designed to help find information stored on a computer system such as the World Wide Web, or a personal computer.

The search engine allows one to ask for content meeting specific criteria (typically those containing a given word or phrase) and retrieves a list of references that match those criteria.

Search engines use regularly updated indexes to operate quickly and efficiently. Without further qualification, search engine usually refers to a Web search engine, which searches for information on the public Web.

Other kinds of search engine are enterprise search engines, which search on intranets and personal search engines, which search individual personal computers.

Some search engines also mine data available in newsgroups, large databases, or open directories like DMOZ.org. Unlike Web directories, which are maintained by human editors, search engines operate algorithmically.

Most web sites which call themselves search engines, are actually front ends to other search engines owned by other companies. The typical user will often not know which underlying search engine they are using.

Internet Chess ToolKit project is a Java library for chess with PGN, FEN, SAN, and ICS (FICS, ICC) support.
Internet Chess ToolKit is a Java-based set of libraries and widgets useful for performing common tasks such as reading SAN (internationalized), FEN, PGN, generating legal moves, and connection to Internet Chess Servers (FICS).
The purpose of the Internet Chess ToolKit is to provide an extensible library to facilitate the development of internet server clients, bots, training programs, peer-to-peer players, and and various other programs useful for the game player. The library was designed with a high level of abstraction and utilization of object oriented design patterns to make it extensible; The model set up should allow for implementations of many games besides Chess, which is the main focus of this library.
Such other games might include chess variants like BugHouse, or completely different games like scrabble and the Chinese game of Go. Another goal of the library is ease of use. A lot of effort has gone into comprehensive documentation and providing sensible names for methods, as well as providing many convenience methods.
Main features:
- FICS support (limited)
- legal move generation.
- game history with variation support (alternative move suggestions).
- move comment support in text and Numeric Annotation Glyphs (NAG).
- Standard Algebraic Notation (SAN) read/write support (internationalized for presentation in 16 languages).
- Portable Game Notation (PGN) read/write support (including move variations, and FEN).
- Forsyth-Edwards Notation (FEN) read/write support.
- True MVC structure with board displays driven by game model events.
- Command-line Board display (GUI to come).
- Well documented. Sample code also provided.
Enhancements:
- Limited FICS support style12, match request, kibitz, whisper, say, tell, channel tell, shout, c/t/-shout, emote, move list, pin, gin, seek ads, seek remove, seek clear, game results
- Timeseal support
- XSLT java code generation for ICS events
- Sample ICS Client
- PGN bugs fixed

Internet Relay Jabber (or IRJ) is a Jabber client for IRC. Its useful if you like IRC, but your friends use another IM service. Through Jabber, IRJ supports AIM, MSN, Yahoo!, ICQ, etc. It is written in Perl and uses Net::Jabber and Net::IRC.

Just to clear up any confusion, this isnt a transport or a gateway between Jabber and IRC (ie, a server component for many users). Is a program for connecting to IRC and Jabber simulataneosly. It then acts as an IRC bot to relay conversations in IRC to Jabber. It is meant for one user per IRJ process and pretty much requires a dedicated IRC channel. It also works best if you have access to a shell sever of some kind (so IRJ can always be running in the background) and use an IRC server with NickServ and ChanServ so you can restrict access to your IRJ channel.

That said, I personally find it very useful (though I may be biased because its my creation) because Im usually on IRC and dont like to have a bunch of other instant messaging programs open as well as my IRC client.
