ntcpclient project is a GPL replacement for tcpclient from ucspi-tcp. I was prompted to write this by Dave Crouse of USALUG for his bbots project. It might be useful to someone else, so here it is. It includes a sample echo client.

It is almost definately more primitive than the ucspi-tcp one. Although I havent used it, or seen the source. In fact, I wrote this under the impression that the program I was replacing was closed source. but it was a nice excuse to write some code.

It works by opening the socket using options passed on the command line (performing hostname lookups and such), creating two pipes then forking. The parent process sits in a loop selecting on the socket/pipe and relaying any data between them. The child just execves with the relevant command line and the socket can be read/written to by simply writing to a numbered file descriptor. Seems always to be 5 and 6, but I think that could change between systems.

Apache2::ModProxyPerlHtml is a mod_perl2 replacement of the Apache2 module mod_proxy_html.c, used to rewrite HTML/Javascript links for a reverse proxy.

Apache2::ModProxyPerlHtml is very simple and has much better parsing/replacement of URL than the C code. It also support refresh meta tag rewriting.

Appctl is a framework for virtually any server software. It provides a central script called "ctl" which allows you to start, stop, restart, maintain, or query the current status of an application.
Appctl is meant as a completely generic replacement for application-specific startup/stop scripts. The project also supplies generic monitoring scripts for clusters, which can dramatically decrease clustering costs.
Enhancements:
- This release includes configuration files for running the Apache Web server with integrated appctl support.

Gammarace project is a vector graphics shooter.

An ode to oldie but goodie. It is a simple game that you can jump into and out of with no instructions. Just attempt to achieve the highest level possible (20 is about the highest unless you are some android from the future bent on killing us.

It was programmed in "D", digitalmars.com. What I consider the replacement for C/C++ and Java.

Anyway, just have fun.

Scons Erlang is an add on for SCons, a make/autotools replacement, to compile Erlang projects.

LIRC Client Daemon project is an attempt to solve certain problems in LIRC.

The LIRC Client Daemon is a per-user daemon that sits between the LIRC daemon (from the Linux InfraRed Control project) and any other programs that use LIRC.

It ships with a replacement library for LIRCs liblirc_client, which connects to lirccd instead of lircd. This primarily helps solve the synchronization present in the standard liblirc_client, and also empowers the user with a much more flexible configuration file format.

runit is a cross-platform Unix init scheme with service supervision; a replacement for sysvinit and other init schemes.
runit project runs on GNU/Linux, *BSD, Mac OS X, snf Solaris, and can easily be adapted to other Unix operating systems. runit implements a simple three-stage concept. Stage 1 performs the systems one-time initialization tasks.
Stage 2 starts the systems uptime services (via the runsvdir program). Stage 3 handles the tasks ecessary to shutdown and halt or reboot.
Enhancements:
- The documentation has been improved, and two minor bugs in the runit and runsv programs have been fixed.
