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

Ice, the Internet Communications Engine, is middleware for the practical programmer. A high-performance Internet communications platform, Ice includes a wealth of layered services and plug-ins. Ice means simplicity, speed, and power.
Ice is available under the terms of the GNU General Public License (GPL). Commercial licenses are available for customers who wish to use Ice with proprietary products. Please contact sales@zeroc.com for more information.
Ice is currently available for C++, Java, C#, Visual Basic, Python, and PHP, and is supported on various operating systems. Additional operating systems and languages will be supported in future releases.
Ice consists of the following packages:
Slice The Specification Language for Ice. Slice establishes a contract between clients and servers, and is also used to describe persistent data.
The Slice Compilers Tools to compile from Slice into target languages, such as C++ and Java, or to automatically generate documentation from Slice files.
Ice The Ice core library. Among many other features, the Ice core library manages all the communication tasks using a highly efficient protocol (including protocol compression and support for both TCP and UDP), provides a flexible thread pool for multi-threaded servers, and additional functionality that supports extreme scalability with potentially millions of Ice objects.
IceUtil A collection of utility functions, such as Unicode handling and thread programming. (C++ only.)
IceBox An application server specifically for Ice applications. IceBox can easily run and administer Ice services that are dynamically loaded as a DLL, shared library, or Java class.
IcePack A sophisticated server activation and deployment tool. With IcePack, the complex task of deploying applications in a heterogeneous computer network is dramatically simplified. Simply write a deployment descriptor in industry-standard XML, and IcePack handles the rest.
Freeze Freeze provides automatic persistence for Ice servants. With just a few lines of code, an application can incorporate a highly-scalable evictor that efficiently manages persistent objects.
FreezeScript It is common for persistent data types to change, especially in large software projects. In order to minimize the impact of these changes, FreezeScript provides inspection and migration tools for Freeze databases. The tools support an XML-based scripting capability that is both powerful and easy to use.
IceSSL A dynamic SSL transport plug-in for the Ice core. It provides authentication, encryption, and message integrity, using the industry-standard SSL protocol.
Glacier One of the most difficult challenges for object middleware systems is security and firewalls. Glacier, the firewall solution for Ice, greatly simplifies the deployment of secure applications. Glacier authenticates and filters client requests and allows callbacks to the client in a secure fashion. In combination with IceSSL, Glacier provides a powerful security solution that is both non-intrusive and easy to configure.
IceStorm A messaging service with support for federation. In contrast to most other messaging or event services, IceStorm supports typed events, meaning that broadcasting a message over a federation is as easy as invoking a method on an interface.
IcePatch A patching service for software distributions. Keeping software up-to-date is often a tedious task. IcePatch automates updating of individual files as well as complete directory hierarchies. Only files that have changed are downloaded to the client machine, using efficient compression algorithms.
Enhancements:
- Various additions, including redundant IceGrid registries.

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.

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.

Gip is an IP address calculator that integrates well with the GNOME desktop environment.

Gip provides system administrators with tools for IP address based calculations. For example, an administrator who needs to find out which IP prefix length equals the IP netmask 255.255.240.0, just types in the mask and gets the prefix length presented. But many more advanced calculations can be made.

Gip can convert an address range into a list of prefix lengths. It can also split subnets using a given IP netmask or IP prefix length. Many more calculations are possible.
