MemMXtest is a computer program for "IBM-compatible" PCs that checks the computer's main memory for faults and defects. (Note however, that no program can be guaranteed to detect all faults, due to their very nature.) This program is aimed specifically at testing SDRAM memory modules (`DIMMs'), and uses MMX instructions to read/write all 64 databits provided by these modules at once. MemMXtest incorporates many well-known `march' tests, as well as several pseudo-random tests. The vital parts of each test use manually optimized machine code for maximal speed. The program is "stand-alone" (i.e. doesn't require an OS to run), and compiles on Linux.
J/CoMM is an OS independent RS232 remote control. The system has a client/server architecture, has an adjustable HTML GUI, and includes drivers for cameras and beamers (e.g., EIKI LC-XM1/SM1/VM1). The server runs on the computer where the devices are connected via RS232. The client can be any computer having a Web browser, JRE, and access to the device control Web site on the server. The Web page (GUI) communicates with the server through an embedded Java applet (RMI).
ServoMaster provides hardware independent abstractions to servos and servo controllers. It has implementations for several servo controller families, including Phidget, Pololu, Parallax, and SSC. It has support for servo and controller metadata, introspection, and capabilities discovery.
