just is a handy way to save and run project-specific commands. Commands, called recipes, are stored in a file called justfile with syntax inspired by make. Linux, MacOS, Windows, and other reasonable unices are supported with no additional dependencies. Errors are specific and informative, and syntax errors are reported along with their source context. Recipes can accept command line arguments. Wherever possible, errors are resolved statically. Unknown recipes and circular dependencies are reported before anything runs. just loads .env files, making it easy to populate environment variables. Recipes can be listed from the command line. Command line completion scripts are available for most popular shells. Recipes can be written in arbitrary languages, like Python or NodeJS. just can be invoked from any subdirectory, not just the directory that contains the justfile.

JED is a drop-in replacement for the EMACS editor, which has gotten very large and slow. The keybindings are almost entirely the same as gnu-emacs. It can be found as /usr/local/bin/jed on most vendor systems. It is must more lightweight and faster than gnu-emacs, and should be used for most simple text editing tasks, such as e-mail. It is especially recommended for users on the central mail servers as an faster alternative to emacs.

A game to learn (or teach) how to use standard commands in a Unix shell.

Teaching first-year university students or high schoolers to use a Unix shell is not always the easiest or most entertaining of tasks. GameShell was devised as a tool to help students at the Université Savoie Mont Blanc to engage with a real shell, in a way that encourages learning while also having fun. The original idea, due to Rodolphe Lepigre, was to run a standard bash session with an appropriate configuration file that defined "missions" which would be "checked" in order to progress through the game.

Available in English, French and Italian.

GameShell should work on any standard Linux system, and also on macOS and BSD (but we have run fewer tests on the latter systems). On Debian or Ubuntu, the only dependencies (besides bash) are the gettext-base and awk packages (the latter is generally installed by default). Some missions have additional dependencies: these missions will be skipped if the dependencies are not met.

Resty provides a simple, concise shell interface for interacting with REST services. Since it is implemented as functions in your shell and not in its own separate command environment you have access to all the usual shell tools. Cookies are supported automatically and stored in a file locally. Most of the arguments are remembered from one call to the next to save typing. It has pretty good defaults for most purposes. Additionally, resty allows you to easily provide your own options to be passed directly to curl, so even the most complex requests can be accomplished with the minimum amount of command line pain.

Implemented as a shell script that you source: . /path/to/resty

Basically, Resty lets you treat HTTP requests to a REST API like a series of CLI commands.

My first test of RTL-SDR to read signals from a water meter transmitter using the rtl_433 utility.

This is supposed to be a follow-up to my Reddit post in r/RTLSDR sub.

A utility which turns any shell command into a REST API.

Mitogen is a Python library for writing distributed self-replicating programs.

There is no requirement for installing packages, copying files around, writing shell snippets, upfront configuration, or providing any secondary link to a remote machine aside from an SSH connection. Due to its origins for use in managing potentially damaged infrastructure, the remote machine need not even have free disk space or a writeable filesystem.

It is not intended as a generic RPC framework; not intended for direct use by consumer software.

The focus is to centralize and perfect the intricate dance required to run Python code safely and efficiently on a remote machine, while avoiding temporary files or large chunks of error-prone shell scripts, and supporting common privilege escalation techniques like sudo, potentially in combination with exotic connection methods such as WMI, telnet, or console-over-IPMI.

Snips NLU (Natural Language Understanding) is a Python library that allows to parse sentences written in natural language and extracts structured information. Behind every chatbot and voice assistant lies a common piece of technology: Natural Language Understanding (NLU). Anytime a user interacts with an AI using natural language, their words need to be translated into a machine-readable description of what they meant. The NLU engine first detects what the intention of the user is (a.k.a. intent), then extracts the parameters (called slots) of the query. The developer can then use this to determine the appropriate action or response.

Shell In A Box implements a web server that can export arbitrary command line tools to a web based terminal emulator. This emulator is accessible to any JavaScript and CSS enabled web browser and does not require any additional browser plugins. Probably more heavyweight than SSH but it also affords certain advantages.
