A system for managing programming contests on the Web. Written in Iava, source code available.
A nice feature is that it does not use a database for the backend, but organizes the information into files and directories in the filesystem.
Peek creates animated GIF screencasts using FFmpeg and ImageMagick. It was built for the specific use case of recording screen areas, e.g., for easily showing UI features of your own apps or for showing a bug in bug reports. It is not a general purpose screencast app with extended features and it never will be.

Rofi started as clone of simpleswitcher, written by Sean Pringle a popup window switcher roughly based on superswitcher. Simpleswitcher laid the foundations and therefor Sean Pringle deserves most of the credit for this tool. Rofi, renamed as it lost the simple property, has been extended with extra features, like a run-dialog, ssh-launcher and can act as a drop-in dmenu replacement, making it a very versatile tool.
Rofi, like dmenu, will provide the user with a textual list of options where one or more can be selected. This can either be, running an application, selecting a window or options provided by an external script.
InfluxData is for IoT deployments requiring support for thousands of sensors. Collect, store, visualize and alert on time-series data emitted from ARM, Arduino, Raspberry Pi and more.
way-cooler - Customizable Wayland compositor (window manager) written in Rust.
Nootka gives real-time feedback, has multiple difficulty levels, and is customizable.
script is an open source tool that makes a typescript of everything displayed on your terminal. It is useful for students who need a hardcopy record of an interactive session as proof of an assignment, as the typescript file can be printed out later with lpr.
Everything between the script and the exit command is logged to the file. This includes the confirmation messages from script itself (unless the -q flag is used). Everything between the script and the exit command is logged to the file. This includes the confirmation messages from script itself.
Recorded shell sessions can be shared using online services. The advantage of sessions recorded in this format from the usual screencasts is that shell instructions can be easily copy/pasted from the player screen.
Useful command:
script --timing=time.txt script.logand to replay
scriptreplay --timing=time.txt script.logSee also the nice -d (divisor, speeds up playback) and -m (max delay in playback) options for replay.
An extremely simple, pluggable static site generator.
GNU TeXmacs is a free wysiwyw (what you see is what you want) editing platform with special features for scientists. The software aims to provide a unified and user friendly framework for editing structured documents with different types of content (text, graphics, mathematics, interactive content, etc.). The rendering engine uses high-quality typesetting algorithms so as to produce professionally looking documents, which can either be printed out or presented from a laptop.
Syncthing replaces proprietary sync and cloud services with something open, trustworthy and decentralized. Your data is your data alone and you deserve to choose where it is stored, if it is shared with some third party and how it's transmitted over the Internet.
zbackup is a globally-deduplicating backup tool, based on the ideas found in rsync. Feed a large .tar into it, and it will store duplicate regions of it only once, then compress and optionally encrypt the result. Feed another .tar file, and it will also re-use any data found in any previous backups. This way only new changes are stored, and as long as the files are not very different, the amount of storage required is very low. Any of the backup files stored previously can be read back in full at any time. The program is format-agnostic, so you can feed virtually any files to it.
This is achieved by sliding a window with a rolling hash over the input at a byte granularity and checking whether the block in focus was ever met already. If a rolling hash matches, an additional full cryptographic hash is calculated to ensure the block is indeed the same. The deduplication happens then.
