Dia2Postgres is a Perl script that can be used to convert Dia diagrams into PostgreSQL scripts or PHP mirror classes which can add, update, and modify table entries automatically. It has support for inheritance, simple references (limited to a single field), and a fake enum type which creates a table.
Barter is a tool for increasing the quality of applications written in Java. It allows the programmer to use design by contract and define other development aspects right in the classes and interfaces where they are relevant, as JavaDoc comments. It is essentially a code generator for AspectJ, implemented as an xDoclet task.
SPYCE is a server-side language that supports simple and efficient Python-based dynamic HTML generation, otherwise called Python Server Pages. Those who like Python and are familiar with JSP, PHP, or ASP should have a look at Spyce. Its modular design makes it very flexible and extensible. It can also be used as a command-line utility for static text pre-processing or as a Web-server proxy.
distcc is a parallel build system that distributes compilation of C/C++/ObjC code across machines on a network. It can be set up in just a few minutes and makes builds up to ten times faster. It does not require machines to share a filesystem or have the same libraries or header files, and installation does not need superuser privileges.
EmPy is a system for embedding Python expressions and statements in template text. It takes an EmPy source file, processes it, and produces output. This is accomplished via expansions, which are special signals to the EmPy system and are set off by a special prefix (by default the at sign, '@'). It can expand arbitrary Python expressions and statements in this way, as well as a variety of special forms. Textual data not explicitly delimited in this way is sent unaffected to the output, allowing Python to be used in effect as a markup language. Also supported are callbacks via hooks, recording and playback via diversions, and dynamic, chainable filters. The system is highly configurable via command line options and embedded commands.
