SMPlayer is a complete media player for Windows and Linux. It uses MPlayer as a playback engine, which is capable of playing most video and audio formats (AVI, mkv, WMV, MP4, MPEG, etc.). It can also play and download YouTube videos. One of the most interesting features is that it remembers the settings of all files you play. So if you start to watch a movie but have to leave, when you open that movie again it will resume at the same point you left it, and with the same settings: audio track, subtitles, volume, etc.
RHEED for Linux is designed to aquire data from RHEED (Reflection High Energy Electron Diffraction) images in Molecular Beam Epitaxy and for controlling an electron beam gun.

The Electron Beam Gun EK35BR from Staib Instruments is supported.
