All I did was move some elements around to compensate for the background.

The Legion of the Bouncy Castle Java Cryptography API provides a lightweight cryptography API in Java. A provider for the JCE and JCA, a clean-room implementation of the JCE 1.2.1, generators for Version 1 and Version 3 X.509 certificates, generators for Version 2 X.509 attribute certificates, PKCS12 support, and APIs for dealing with S/MIME, CMS, OCSP, TSP, and OpenPGP. Versions are provided for the J2ME, and JDK 1.0-1.5.
Main features:
- A lightweight cryptography API in Java.
- A provider for the JCE and JCA.
- A clean room implementation of the JCE 1.2.1.
- A library for reading and writing encoded ASN.1 objects.
- Generators for Version 1 and Version 3 X.509 certificates, Version 2 CRLs, and PKCS12 files.
- Generators for Version 2 X.509 attribute certificates.
- Generators/Processors for S/MIME and CMS (PKCS7).
- Generators/Processors for OCSP (RFC 2560).
- Generators/Processors for TSP (RFC 3161).
- Generators/Processors for OpenPGP (RFC 2440).
- A signed jar version suitable for JDK 1.4/1.5 and the Sun JCE.

Linux Letters and Numbers project is an educational childrens game for linux.
Linux Letters and Number is a fun and educational learning game intended for children 2 and up.
It helps children learn or improve their letters, numbers, spelling, and vocabulary skills through the use of interesting pictures.
It also helps them develop important computer skills too.
It is written in C using the GTK and GDK_Imlib libraries.
Main features:
- Extensible - add new images yourself without having to make changes to the program. With support for gdk_imlib, you can now use common image formats, including common formats like gif, jpeg, xpm, png, and tiff.
- Dynamic - each letter or number can be represented by numerous pictures, each being displayed randomly.
- Flexible - you can even have more than one picture for a given word, by using a simple versioning scheme (ie Apple.1.xpm, Apple.2.xpm)
- Interesting - because you can change the game, its different every time!

FLAC is a lossless compression method for audio files. Using it, one is able to reduce the filesize and keep the same audio quality as a regular WAV file (CD quality).

The FLAC format is open source, and can be read without any problem by such applications as Amarok or Kaffeine.

Wav and Flac conversion contains two service menus: one to convert WAV files into FLAC, and one to convert FLAC files into WAV.

You will need the FLAC application to be installed on your system to use these service menus.

MiniUPnP Client and Daemon is an UPnP IGD client lightweight library and UPnP IGD daemon.
The UPnP protocol is supported by most home adsl/cable routers and Windows 2K/XP. The aim of the MiniUpnp project is to bring a free software solution to support the "Internet Gateway Device" part of the protocol.
The Linux SDK for UPnP devices (libupnp) seems too heavy for me. I want the simplest library possible, with the smallest footprint and no dependencies to other libraries such as XML parsers or HTTP implementations. All the code is pure ANSI C.
Compiled on a x86 PC, the miniupnp client library have less than 15KB code size. For instance, the upnpc sample program is around 20KB.
The project is divided in two main parts : the client library, enabling applications to access the services provided by an UPnP "Internet Gateway Device" present on the network, and the miniupnpd daemon, providing these services to your network from a linux or bsd box being the gateway. At the moment the miniupnpd is developped on OpenBSD 3.0+ with pf. You can see some of the work I have done to integrate with pf on this page.
As pf is also available under FreeBSD, guys at the pfSense project have ported miniupnpd to this system.
For some reasons, it may be not the good solution for you to use the code from the MiniUPnP project directly.
As the code is small and simple to understand, it is a good base to take inspiration for your own UPnP implementation. The KTorrent team UPnP plugin in C++ is a good example.
If you are wondering which home router is working with the miniupnp client, you can find the answer here. In fact, you are more likely to help me fill the list by sending me an email.
Usefulness of the miniUPnP client library
The usage of the miniUPnP client library is useful whenever an application needs to listen for incoming connections.
Examples : P2P applications, FTP clients for active mode, IRC (for DCC) or IM applications, network games, any server.
The typical usage of UPnP capabilities of a router is a file tranfert using MSN messenger. The MSN Messenger software uses the UPnP API of Windows XP to open port for incoming connection. To mimic the MS software, it is a good idea to use UPnP as well.
Enhancements:
- This release adds changes to accommodate the Linux 2.6.22 kernel.

Naughts and Crosses a simple tic-tac-toe game - with a twist.

This is a simple tic-tac-toe game, written in C++ for the console. Its a very simple affair, and only suited to the odd five minutes, but has a fully functional one-player mode (which I have tried to make neither too easy nor too hard) and offers the ability to modify the board size.
