Check is a unit test framework for C. It features a simple interface for defining unit tests, putting little in the way of the developer. Tests are run in a separate address space, so Check can catch both assertion failures and code errors that cause segmentation faults or other signals. The output from unit tests can be used within source code editors and IDEs.

The PLEAC project aims to re-implement the solutions presented in the Perl Cookbook (by Tom Christiansen & Nathan Torkington, published by O'Reilly) in other programming languages. If successful, this project may become a primary resource for quick, handy, free solutions to most common programming problems using higher-level programming languages. It could also be useful for comparison on ease-of-use and power/efficiency of these languages.
GNU Lightning is a library that generates assembly language code at run time. It is very fast, making it ideal for Just-In-Time compilers, and it abstracts over the target CPU, as it exposes to the clients a standardized RISC instruction set (inspired by the MIPS and SPARC chips).
Aubit 4GL compiler is a programming language based on (and compatible with) Informix-4GL. It provides an easy way to generate screen/form based programs, since statements for handling Windows, Forms, Menus, SQL, and similar are built-in. With support for SQL statements forming an intrinsic part of the language, it's especially suitable for developing database-oriented applications. Database connectivity is provided for PostgreSQL, MySQL, Informix, and others via ODBC. It supports both ncurses (console mode) and GTK+ (GUI mode) output.
The Header and Envelope rewrite mini-HOWTO explains how to rewrite your from address differently in the mail header and the mail envelope.
