GramoFile is intended primarily for transferring gramophone records to CDs, but has many other possible uses. It can record very long .wav files with a bargraph signal peak-level meter, playback any part of the files, split long .wav files into separate tracks (with automatic track location), and process the signal with filters to reduce ticks and pops (multiple filters are provided, they can be applied in any order (multiple instances) with user-adjustable parameters). Track splitting and signal processing are done in the same run, and don't need any temporary files.
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.
