Linux Process Explorer is a graphical process explorer for Linux. It shows process information such as a process tree, TCP IP connections, and graphical performance figures for processes. It aims to mimic Windows procexp from sysinternals, and is more usable than top and ps. Its unique feature is the ability to measure and trend the TCP/IP output of a process.
ArduinoPulseGenerator is a simple program for generating pulse sequences using an Arduino. There is an associated GUI that runs on the local computer, or you can simply connect to the Arduino with a serial console (9600 baud) and send it commands. This code has been tested on the ArduinoMega 2560 (timing accuracy ~ ±200 μs) and Arduino Due (timing accuracy ~ ±35 μs); it may work on other Arduino boards.
