Vanilla is a WikiClone written in REBOL. It is useful for collaboratively working on projects, tracking todo items, managing adresses, and creating Web logs. All page editing takes place in the browser. Vanilla features a simple templating system, a full-featured user and session management system, and an extension architecture for writing simple Web applications in REBOL.
The c-tree Plus embedded database engine offers developers several APIs that provide low-level routines, ISAM-level control, and higher-level interfaces. c-tree Plus is distributed in complete C source, has been ported to 100+ environments and includes a robust database Server SDK. It can be used to develop single user and peer-to-peer applications, or the client-side for applications using FairCom's database server, the c-tree Server.
mach allows you to set up clean roots from scratch for any distribution or distribution variation supported. Currently, this is limited to RPM-based distributions. This clean build root can be used for making clean packages, running jailed services, testing builds, or making disk images of clean roots.
TagSoup is a SAX-compliant parser written in Java that, instead of parsing well-formed or valid XML, parses HTML as it is found in the wild: poor, nasty, and brutish, though quite often far from short. TagSoup is designed for people who have to process this stuff using some semblance of a rational application design. By providing a SAX interface, it allows standard XML tools to be applied to even the worst HTML. TagSoup also includes a command line processor that reads HTML files, and can generate either clean HTML or well-formed XML that is a close approximation to XHTML.
blinkperl is a telnet server (written in Perl) which plays a random (ASCII-Art) Blinkenlights-Movie if a telnet client connects. In a properly configured system, you do not need a 'usual' telnet server (because of the plaintext password transmission, ssh is better and uses another port), so why not play ASCII-Art Movies on the telnet port?
CodeBeamer allows computer science, engineering, and information systems departments and students to work together on software development projects regardless of their locations. Its Web-based portal provides comprehensive collaborative features (an issue tracker, document manager, and discussion forums) and code browsing for software development teams. It is integrated with Eclipse and other configuration management systems (CVS, PVCS, SourceSafe, ClearCase, CM/Synergy), and can be integrated with existing tools.
r80v5 is a fast, lightweight HTTP server written in REBOL, supporting the execution of server-side REBOL code embedded in HTML files. It is easily extended by mapping modules to a resource pattern. For example, one module could be called for all *.txt files, but a different module could be used for all *.txt files in the directory 'source/'.
Perthon converts Python source code to human- readable Perl 5.x source code. It makes use of Damian Conway's Parse::RecDescent for parsing, and aims to reimplement the Python language as specified in the Python Reference Manual and BNF grammar. Perthon is similar to Jython (www.jython.org), which reimplements Python on the JVM, except that Perthon works at the source code (not byte code) level. Perthon does the reverse of Bridgekeeper (http://www.crazy-compilers.com/bridgekeeper/), which attempts to solve the (much harder) problem of Perl-to-Python source code machine translation.
