Filippo and Ben's new file encryption tool Age, which is meant to replace GPG for sending encrypted files, has reached 1.0! In addition to generating Age specific encryption keys, Age can also use SSH keys, so you can encrypt a file for anyone whose SSH public key you have handy. — davidbalbert

A really fun momentum-based puzzle game made for a Godot game jame. 30 levels! Check out the code here: https://github.com/EmilyBonar/MomenTom. — Mai

Jamie made a video introducing the live REPL for Imp, his relational programming language. The live REPL is embedded in Focus, his text editor (!!). Video is quiet, so crank your volume. — davidbalbert

Some thoughts on learning Elm to write a simple arcade game, along with the playable game and source. — nicholasbs

Tree-grepper searches by looking at code structure instead of strings. This lets you match on whatever structures a language defines without worrying about whitespace! It uses tree-sitter underneath so it's easy to extend, too! — brianhicks

um-abt is a library for working with the abstract syntax of languages that use variables. It provides "unifiable abstract binding trees" (UABTs): abstract syntax trees (ASTs), enriched with constructs to manage variable binding and (nominal) unification. — Shon

Language models built on datasets scraped from the open web have become foundational in natural language processing, but they reflect and amplify the biases and harms of their training data. We created a system which lets us filter training data to build more value-aligned models. It's imperfect—the internet is really big, harmful text is ever-evolving, and human labels include human biases. But little-by-little, we get closer to friendlier models! — mathemakitten

Jim is working on a vocoder at RC currently! You can read about it on his blog and check out the code here: https://github.com/jimkang/channel-vocoder. — Mai

A clever way to automatically format (and thus be able to see) all the cells in a Google Sheets spreadsheet that are intended to be inputs. — nicholasbs

Add tags to your starred repos on GitHub, so you never again lose track of that plugin or parser you totally meant to install. — rachel
