fxopt is a plugin for GCC that converts floating-point functions to fixed-point arithmetic, primarily for implementation in embedded, real-time systems without floating-point hardware. The conversion is performed in GCC's "middle-end", after the source code has been converted to GCC's intermediate representation but before any target-specific optimizations are done. Several optimization options are available to improve the accuracy of the fixed-point arithmetic, including affine range estimation, rounding, and double-precision multiplications. Fixed-point code produced by fxopt can be significantly more accurate than typical fixed-point implementations with comparable execution time and code size. In many cases the fixed-point code produced by fxopt provides accuracy comparable to single-precision floating-point arithmetic with a factor of 10 faster execution.
With LinkChecker, you can check HTML documents and Web sites for broken links. It features recursion, robots.txt exclusion protocol support, HTTP proxy support, i18n support, multithreading, regular expression filtering rules for links, and user/password checking for authorized pages. Output can be colored or normal text, HTML, SQL, CSV, or a sitemap graph in DOT, GML, or XML format. Supported link types are HTTP/1.1 and 1.0, HTTPS, FTP, mailto:, news:, nntp:, Telnet, and local files.
Embedthis Appweb is a fast, little embedded Web server. It is unmatched in efficiency and serves pages at native speed, using an event-driven, non-blocking core to serve multiple requests using minimal resources. It has integrated caching and the ESP "C" Web framework. Without compromising performance, it has extensive security controls and a rigorous security sandbox that helps protect the server and mitigate denial-of-service attacks. It is one of the most widely deployed embedded Web servers and is used in networking equipment, telephony, mobile devices, industrial control, and consumer and office equipment, and in high-performance Web services.
Seafile is a file synchronization and collaboration platform. It comes with Dropbox-like file syncing, but is designed to be better suited to teamwork. You can build a file syncing and collaboration service for your team on your servers. It can also be used to build your own Dropbox for personal use.
Micro Snake is based on a simple snake game by Simon Huggins. This version of the snake (worm) game is very small and only utilizes ANSI escape sequences to draw the board. Hence it is very suitable for small embedded systems with only serial or SSH console access. The code uses no curses or other heavy libraries, only ANSI escape sequences and the Unix "stty" command to setup and restore the display.
LiVES is a simple to use yet powerful video effects, editing, conversion, and playback system aimed at the digital video artist and VJ. It runs under Linux, BSD, Mac OS X/Darwin, IRIX, and openMosix. It is frame and sample accurate, can handle almost all types of video, and is fully extendable through plugins and the included plugin builder tool. It can also be controlled remotely using OSC.
