Contiki is an open source, highly portable, networked, multi-tasking operating system for the Internet of Things. Contiki includes a multitasking kernel, a TCP/IP stack and a set of application programs, and a low-power radio communication stack. It is written in C and designed to be very small: it runs comfortably in a few kilobytes of RAM.
PHP Error aims to make understanding initial error reporting as fast as possible. When an error strikes, you get a full syntax-highlighted stack trace, with code snippets from the relevant files and improved error messages, displayed with CSS3. It works for AJAX requests, too, with no JS changes or plugins required.
uIP is probably the smallest implementation of the TCP/IP protocol stack ever written in a high level language; the code footprint is on the order of a few kilobytes and RAM usage is on the order of a few hundred bytes. uIP is intended to be used in embedded systems running low end 8- and 16-bit microcontrollers.
freshmeat Project Query Class queries freshmeat.net and retrieves information on projects with records there. It features retrieval of project information from records provided by freshmeat in XML, parsing of project XML records to extract all the relevant data, and caching of retrieved project information in disk files for at least the next day to avoid retrieving the same data again before it could have been updated.
