Lzip is a lossless data compressor with a user interface similar to the one of gzip or bzip2. Lzip can compress about as fast as gzip (lzip -0) or compress most files more than bzip2 (lzip -9). Decompression speed is intermediate between gzip and bzip2. Lzip is better than gzip and bzip2 from a data recovery perspective. Lzip has been designed, written and tested with great care to replace gzip and bzip2 as the standard general-purpose compressed format for unix-like systems.
The lzip file format is designed for data sharing and long-term archiving, taking into account both data integrity and decoder availability:
- The lzip format provides very safe integrity checking and some data recovery means. The lziprecover program can repair bit flip errors (one of the most common forms of data corruption) in lzip files, and provides data recovery capabilities, including error-checked merging of damaged copies of a file.
- The lzip format is as simple as possible (but not simpler). The lzip manual provides the source code of a simple decompressor along with a detailed explanation of how it works, so that with the only help of the lzip manual it would be possible for a digital archaeologist to extract the data from a lzip file long after quantum computers eventually render LZMA obsolete.
- Additionally the lzip reference implementation is copylefted, which guarantees that it will remain free forever.
The suffix .lz is used for files compressed with lzip.

You can simply program an Attiny85 via the audio output of a PC, Smartphone or audio-player.

Only a low-part count circuit is needed.

The bootloader presented here has the following features:
   low memory footprint: ~1KB
   [full Arduino IDE integration] (https://github.com/8BitMixtape/8Bit-Mixtape-NEO/wiki/3_3-IDE-integration)
   automatic Baudrate detection and callibration
   very simple circuit: two 10 k resistors and a 100 nF capacitor are needed to connect the microcontroller to the audio output of the PC or audio player
   one pin for data transmission is needed
   an optional led indicator, needs an extra pin, for the state of the boot loader
   as hex/binary to wav converter, programmed in java, is also available. It works on win and linux

Apache Guacamole is a clientless remote desktop gateway. It supports standard protocols like VNC, RDP, and SSH.

We call it clientless because no plugins or client software are required.

Thanks to HTML5, once Guacamole is installed on a server, all you need to access your desktops is a web browser.

Yet another password manager.

GMAT is designed to model, optimize, and estimate spacecraft trajectories in flight regimes ranging from low Earth orbit to lunar applications, interplanetary trajectories, and other deep space missions. Analysts model space missions in GMAT by first creating resources such as spacecraft, propagators, estimators, and optimizers.

Program to allow a Unix machine to open documents on a Windows machine (for example, sending commands back to your Windows desktop machine from a Unix server you've connected to from there).

SILE is a typesetting system. Its job is to produce beautiful printed documents.
SILE follows TeX in each of these three areas; it contains a slavish port of the TeX line-breaking algorithm which has been tested to produce exactly the same output as TeX given equivalent input. But as SILE is itself written in an interpreted language, it is very easy to extend or alter the behaviour of the SILE typesetter.
