phpSearchDoc is a program that aims to do for PHP developers what Javadoc does for java developers. It is a script that parses PHP class definitions, extracting function and variable names, as well as comments, and dumping this data into a database. The script itself is built in Perl, but PHP is used for search and display. Search is powered by SearchForms, and display by EnzymeTemplates (both are GPL modules released as part of the Enzyme open-source project).
PicMonger is a GUI-driven app that scans a specified Usenet newsgroup for binary attachments. Any attachments encoded with uuencode or in MIME-base64 format are decoded into the current working directory. Lists of frequently used servers and groups are saved on a per-user basis and easily accessed/edited via the GUI. HTML preview pages (like contact sheets) can be automatically generated on the fly. PicMonger also remembers where you were between sessions so scanning resumes where you left off.
picoTK is a C GUI toolkit that requires only a minimum of memory resources. It is intended for embedded system use, especially for (but not limited to) the RTEMS realtime kernel. It is in no way comparable featurewise to a "real" full blown windows toolkit like Qt or nanoX; it rather provides simple drawing primitives like lines, filled rectangles, characters, and pixmaps. (But that is what many embedded applications might ask for.) It directly works on tailored "framebuffer" hardware. A Linux framebuffer emulator is supplied as part of the kit, making evaluation (and emulation!) possible without having a realtime OS and custom hardware.
pikipiki is a cooperative authoring system for the Web. It is written in Python with a strong emphasis on small, simple code, so it is well suited for adaption into your own custom Wiki. pikipiki is in the WikiWiki genre: anyone may contribute to the hypertext, and the system is intentionally minimal to encourage cooperation and community between users. pikipiki is the parent of the more featureful and complex MoinMoin system.
