WSJT
Weak signal ham radio communication
The WSJT project implements software for amateur radio communication using state-of-the-art digital techniques. Typical applications involve "DXing" at LF, MF, HF, and VHF+ frequencies, including meteor scatter and EME ("moonbounce"). Major emphasis is placed on weak-signal techniques. Summary Program Descriptions: WSJT-X supports the communication protocols FST4, FT4, FT8, JT4, JT9, JT65, Q65, MSK144, WSPR, FST4W, and Echo, each optimized for different sorts of radio-wave propagation. MAP65 and QMAP are designed for EME at VHF and higher frequencies. MAP65 provides a panoramic, polarization-matching receiver for the Q65 and JT65. modes. QMAP works together with WSJT-X to provide a panoramic receiver for Q65 modes covering a 90 kHz sub-band. Programs WSJT and WSPR are interesting primarily for historical reasons. They are superseded by WSJT-X. -

Barrier
Open-source KVM software
Barrier is a software that works just like a KVM (keyboard, video and mouse) switch, which allows you to use a single mouse and keyboard to control several different computers by physically turning a dial on the box to switch the machine you're controlling at any given time. Barrier is able to do this in software, giving you control over different machines by simply moving your mouse to the edge of the screen, or by using a keypress to switch focus to a different system. Barrier was built to be simple and reliable, allowing you to control a different machine by simply using your mouse and keyboard from another. It works on all major operating systems (Linux, Windows, MacOS/OS X), including FreeBSD and OpenBSD. -
