The Apache/Perl integration project brings together the full power of the Perl programming language and the Apache HTTP server. With mod_perl it is possible to write Apache modules entirely in Perl. In addition, the persistent interpreter embedded in the server avoids the overhead of starting an external interpreter and the penalty of Perl start-up time.
peekabot is a versatile 3D visualization tool targeted at robotics researchers and developers. It's multi-platform, general purpose, easily extendable, scalable, and does not depend on any other frameworks to function. It also provides some functionality for interacting with your robots using the GUI. You can test your algorithms in both simulated and real environments. The only requirement is that the device can use TCP/IP.
Werc is a minimalistic RESTful Web application framework and content management system. It follows the Unix "tool philosophy" and it is designed to be fast, simple, convenient, and easily extensible. It handles both small and big sites and has a flexible system for user and group permissions. All data is stored in plain text files that can be easily manipulated with standard tools, without using any databases or other external dependencies. Existing applications include a blogging engine with RSS/Atom feeds, a wiki system that can easily integrate pre-existing documents (can be enabled for any directory tree), and others.
The Amazing Awk Assembler (aaa) is a primitive assembler written entirely in awk and sed. It is quite slow, the input syntax is eccentric and rather restricted, and error checking is virtually nonexistent, but it does work. Furthermore it's very easy to adapt to a new machine, provided the machine falls into the generic "8-bit-micro" category.
wxFreeChart is powerful charting library based on wxWidgets. It is designed with flexibility in mind, and supports many types of charts with many different configurations. These include line/histogram charts base on x/y coordinates, bar charts (vertical or horizontal), stacked bar charts, layered bar charts, OHLC financial charts (bars or candlesticks), pie charts, bubble charts, and Gantt charts.
Falcon is a simple, fast, and powerful programming language, easy to learn and to feel comfortable with. It is also a scripting engine, easily embeddable in any complex, multi-threaded and mission-critical application. Falcon provides its users with four integrated programming paradigms: procedural, object oriented, functional, and message oriented. And you don't have to master all of them; you just need to pick the paths that are ingredients you prefer, and let the code to follow your inspiration.
