RPilot is an interpreter for the IEEE-standard programming language PILOT written in portable C. PILOT is a language that was designed in the 1960's to support computer-aided instruction and is very simple to learn. RPilot comes with an introduction to the language and several examples.
Pklinux-bigi is a Slackware derived distribution based on glibc 2.2 and Linux 2.4.0-test11. It can run on 386, 486, 586, and Pentium machines with only 4 MB of RAM. Builtin features include IP tunneling, firewalling, encapsulation, QOS(based on ipv4 RSVP), kernel debugging, loopback, network block device, and numerous filesystems (including ntfs and sysV). It contains Apache, proftpd, bind 9.0, syslogd, sendmail, iptables, iproute2, and gated. NAT configuration by iptables is included by default. It is a loopdisk based distribution which can be directly run from DOS, no hdd partitioning needed. This distribution is kept as minimal as possible and it can be useful in places where you want a low end computer to act as a firewall, webserver, mail server, router, or an alternative to zipslack.
Mercat is a light-weight, cross platform programming language. It is garbage collected and self hosting and produces portable byte-compiled binaries that can be executed on any platform with the appropriate interpreter. Interpreters are available for Linux, DOS (32-bit) and DOS (16-bit) and the interpreter source should be easily compilable for other platforms.
ICI is a general purpose interpretive programming language that has dynamic typing and flexible data types with the flow control constructs and operators of C. It is designed for use in many environments, including embedded systems, as an adjunct to other programs, as a text-based interface to compiled libraries, and as a cross-platform scripting language with good string-handling capabilities.
distributed.net is a loosely knit group of computer users from all of the world that is taking up challenges requiring lots of computing power (most notably the RC5, DES, and OGR cracking contests). It is simple to participate in the challenges by downloading and running their client software (which uses idle CPU time to complete its tasks).
DeuTex is a wad composer for Doom, Heretic, Hexen and Strife. It can be used to extract the lumps of a wad and save them as individual files. Conversely, it can also build a wad from separate files. When extracting a lump to a file, it does not just copy the raw data, it converts it to an appropriate format (such as PPM for graphics, .au for samples, etc.). When it reads files for inclusion in pwads, it does the necessary reciprocal conversions. In addition, DeuTex has functions such as merging wads, etc.
