rpi_gpio_ntp enables you to connect a GPS module with a PPS signal (or any other PPS source) to a Raspberry Pi, then sync the local clock using NTP. This can give you very accurate timekeeping. When you use this program, you do not need to patch the kernel to get PPS support, and do not need to patch the NTP program.
SNOW is a utility for concealing messages in ASCII text by appending whitespace to the end of lines. Because spaces and tabs are generally not visible in text viewers, messages concealed with whitespace are effectively hidden from casual observers. If SNOW's built-in encryption is used, the message cannot be read even if it is detected. SNOW exploits the Steganographic Nature Of Whitespace, similar to finding a polar bear in a snowstorm; hence the name.
Singhala keymap provides a means for typing Dual-script Singhala. It is preferably added to the top of the "lk" layout file at X11/xkb/symbols/pc/lk. It is use for romanized Singhala, which fully covers the three languages Singhala, Sanskrit, and Pali. The text typed using it can be displayed in the Singhala script when displayed using orthographic smart-fonts. Where there is no Singhala font available, the text appears as readable Latin text.
ftracer is a simple user space implementation of a Linux kernel style function tracer. It allows you to trace every call in instrumented user applications. It is useful for debugging and performance analysis due to its fine grained time stamp. This allows you to do control flow oriented debugging without any special instrumentation. So if the program does something unexpected, it's easily possible to look at the function calls before that, and use that to deduce the cause of the problem. ftracer relies on gcc generating a call on top of every function call. The tracing slows every function call down (about 3x). The tracing is per thread and does not create a global bottleneck. It supports a dump function in C, directly callable by the program or on exit, and a gdb function to dump from gdb.
