Minimal Linux Live can be downloaded as a pre-built image, built from scratch or run in a web browser by using a JavaScript PC emulator.

    Babashka

    Babashka

    Native, fast starting Clojure interpreter for scripting

    Avoid switching between Clojure and bash scripts. Enjoy your parens on the command line. Leveraging GraalVM native-image and the Small Clojure Interpreter, babashka is a self-contained and instantly starting scripting environment. Babashka comes with scripting batteries included: tools.cli, cheshire, babashka.fs, babashka.process, java.time and many more libraries and classes. Babashka scripts work on linux, macOS and Windows. Besides the built-in libraries, babashka is able to load libraries from source, tapping into the world of already existing Clojure libraries. Babashka supports real JVM threads and like Clojure, supports futures and dynamic thread-locally bound vars. Babashka features a built-in task runner which covers the most popular use cases of make, just and npm scripts. Babashka can shell out to other CLI programs like you are used to in bash. It goes one step further and offers seamless integration with other binaries using the pod protocol.

    homeshick

    homeshick

    git dotfiles synchronizer written in bash

    In Unix, configuration files are king. Tailoring tools to suit your needs through configuration can be empowering. An immense number of hours is spent on getting these adjustments just right, but once you leave the confines of your own computer, these local optimizations are left behind. By the power of git, homeshick enables you to bring the symphony of settings you have poured your heart into with you to remote computers. With it you can begin to focus even more energy on bettering your work environment since the benefits are reaped on whichever machine you are using. However bare bones these machines are, provided that at least Bash 3 and Git 1.5 are available you can use homeshick. homeshick can handle multiple dotfile repositories. This means that you can install larger frameworks like oh-my-zsh or a multitude of emacs or vim plugins alongside your own customizations without clutter.

    Kubetail

    Kubetail

    Bash script to tail Kubernetes logs from multiple pods

    Bash script that enables you to aggregate (tail/follow) logs from multiple pods into one stream. This is the same as running "kubectl logs -f " but for multiple pods. Just download the kubetail file (or any of the releases) and you're good to go. Note that you may need to run compinit for zsh to pick-up the changes in the competition after having upgraded from the non-abbreviated installation. If you're using a ZSH plugin manager, you can install kubetail as a plugin. kubetail itself doesn't have filtering or highlighting capabilities built in. If you're on MacOSX I recommend using iTerm2 which allows for continuous highlighting of search terms, good scrolling capabilities, and multitab arrangements. Another useful feature of iTerm2 is the "timeline" (cmd + shift + e) which lets you display a timeline in your own local timezone next to the logs (that are typically in UTC).

    fish

    fish

    The user-friendly command line shell

    Finally, a command line shell for the 90s. fish is a smart and user-friendly command line shell for Linux, macOS, and the rest of the family. fish suggests commands as you type based on history and completions, just like a web browser. Watch out, Netscape Navigator 4.0! fish supports 24 bit true color, the state of the art in terminal technology. Behold the monospaced rainbow. fish is fully scriptable, and its syntax is simple, clean, and consistent. You'll never write esac again. For those lucky few with a graphical computer, you can set your colors and view functions, variables, and history all from a web page. Other shells support programmable completions, but only fish generates them automatically by parsing your installed man pages. fish will delight you with features like tab completions and syntax highlighting that just work, with nothing new to learn or configure.

    Kobo XCSoar Launcher

    a customizable boot menu for your Kobo Mini

    Mainly this project aims at easing startup and use of XCSoar (see xcsoar.org) on Kobo Mini. But the scope of use should not be limited solely to XCSoar. The Launcher should be small in code size, reuse most of the original libraries, provide flexible configuration to any application that might be ported to the Kobo Mini. It supports customizable fonts, toolbox-pages, buttons (also graphical), labels, autostart and sleep timers.
