Avoid The Roid 3D project is a 3D asteroids-like multiplayer game.

The player flies around in a three dimensional space, shooting asteroids and other ships while trying to avoid running into any of them or being shot.

The game is written in c++ and uses unix sockets for networking, pthreads for the thread library, OpenGL for the graphics library, glut for windows and input, and OpenAL for audio.

Health Tip Buddy Email System is a nice tool you can add to your web site that will allow your visitors to sign up for an automatic health-tip email list.
Its easy to change the look and feel of the e-mails to match your web site, and the system allows for e-mail restrictions so that you dont make your hosting provider unhappy.
Main features:
- Installation is easy, just upload the script and run the install file to automatically install your database tables and set up your configuration.
- Set the time between mailings. Want a weekly e-mailing? Daily? No problem you set the length.
- Easily set how many e-mails can be sent in a day or hour to avoid getting on your hosting providers bad side. The e-mails are stored and those that cant be sent right away will be sent later.
- Add custom health tips of your own!
- Visitor sign-up script includes a Captcha device to avoid automated signups by spammers.

radlib is a C language library developed to abstract details of interprocess communications and common linux/unix system facilities so that application developers can concentrate on application solutions.
It encourages developers (whether expert or novice) to use a proven paradigm of event-driven, asynchronous design.
By abstracting interprocess messaging, events, timers, and any I/O device that can be represented as a file descriptor, radlib simplifies the implementation of multi-purpose processes, as well as multi-process applications.
radlib greatly improves typical process performance through the use of shared memory buffers to avoid costly "malloc" and "free" library calls.
These buffers are also used for interprocess messages. radlib also utilizes shared memory constructs to provide global message queue management and global "Queue Groups" for increased interprocess communications flexibility.
All shared resources are semaphore protected to avoid issues with concurrent access.
In short, radlib is a sincere attempt to provide real-time OS capability on a non-real-time OS. It has been successfully deployed on linux, MacOSX and FreeBSD but there is no reason it would not build and run on any flavor of unix supporting System V IPC.
Specifically, radlib provides fast system buffers, a simple config file utility, events, doubly-linked lists, process logging through syslog, message queues, semaphores, shared memory utilities, timers, stacks, state machine utilities, a process framework, a process management utility to start/stop groups of processes, optional MySQL or PostgreSQL database API, straightforward TCP/streams socket API, and other assorted system utilities.
Enhancements:
- hanged some database field processing to comply with the postgresql changes made in version 8.

bsidentd provides a minimal and secure identd server that can generate random usernames.
bsidentd is a bare minimum and secure identd server, based on nullidentd. It can generate a random string for a username. It makes IRC servers happy, and it helps avoid ban scripts by not having a fixed username.
Alternately, a fixed username can be specified on the command line.
Installation? The usual. Check the makefile, make install then add an entry to
inetd.conf:
auth stream tcp nowait nobody /usr/sbin/tcpd /usr/local/sbin/nullidentd
Enhancements:
- Added query limit.
- Patch from Sven Oliver Moll to allow a username to be specified on the command line. bsidentd can now fully replace nullidentd.
- Debian package

Mail2sh is a tool for send shell command by email with a simple module and to avoid you to know how procmail and sendmail works. Mail2sh makes it possible to carry out shell commands by email. Email is sent to a particular user on your host and the commands will be carried out if the user and password given matches ones in /etc/passwd. Commands are executed with the users privileges, and combined with a PGP module ensures a certain level of security for use. Note that the system is not natively encrypted, so use of an encryption mechanism is very recommended for security reasons.

mod_perl project brings together the full power of the Perl programming language and the Apache HTTP server. You can use Perl to manage Apache, respond to requests for web pages and much more.

mod_perl gives you a persistent Perl interpreter embedded in your web server. This lets you avoid the overhead of starting an external interpreter and avoids the penalty of Perl start-up time, giving you super-fast dynamic content.

As youd expect from the Perl community, there are hundreds of modules written for mod_perl, everything from persistent database connections, to templating sytems, to complete XML content delivery systems. Web sites like Slashdot and Wired Magazine use mod_perl.

mod_perl is an Apache Software Foundation project. It is licensed under the Apache Software License.

Eukleides is a Euclidean geometry drawing language. Two softwares are related to it. First, eukleides, a compiler which allows to typeset geometric figures within a (La)TeX document.

This program is also useful to convert such figures in EPS format or in various other vector graphic formats.

Second, xeukleides, a GUI front-end which makes possible to create interactive geometric figures. This program is also useful to edit and tune some Eukleides code.

Eukleides has been designed in order to be close to the traditional language of elementary Euclidean geometry. In many cases, it makes possible to completely avoid the use of Cartesian coordinates. You may want to have a look at some samples to see part of the languages features.
