Perl Pop3 is a POP3 server fully implemented in Perl. The advantages over other POP3 servers are that it is not a memory hog, and can be used to connect to databases for authentication. Also, its code is easy to extend for any other uses, like POP-before-SMTP and extended logging.
e2 elements is a flexible and modular application development framework optimized for embedded systems. Through a component-based architecture and the strict separation of implementation and interface, the framework encourages reuse and improves backwards compatibility. It is portable over a wide range of environments, but with low memory footprint and an emphasis on simplicity. It is particularly well-suited for constrained environments like uCLinux. Dynamic loading of components and statically-linked applications are possible.
BlueJ with Modified Error Subsystem is a modified version of BlueJ which has had the error reporting subsystem rewritten to find common programming errors that novice programmers make, report these errors in a descriptive way to reiterate the core concepts of programming, and give advice that the student can follow to fix the problem.
Micro fitter searches the best approximation to a set of data points using simple equations (rects and quadratics), and computes the maximum absolute and relative errors for the adjusted interval, the whole data set, or a specified range. It can generate the assembly code to implement it (currently only for Microchip's PIC family of microcontrollers).
