Hi all! TikZ is a widely-used LaTeX package for drawing figures in papers. It uses commands like \draw[-&gt;] (0,0) -- (1,2); to draw lines, shapes, text, etc. Academics usually code up their figures by hand, so there is lots of twiddling around with the coordinates and recompiling until things look nice. I guess it’s a bit like SVG, but it’s more code than markup, for example it has loops with \foreach.I built an open-source WYSIWYG TikZ editor (available for web and desktop) that allows you to edit your TikZ source code visually by dragging and resizing elements. It simultaneously shows the source code and the rendered figure, and lets you edit either one while the two views stay in sync. I’m not aware of any other editors that are simultaneously source editors and WYSIWYG (even for editing SVG or HTML), and I’m quite pleased with how well the combination works.The way the app is implemented is by parsing the TikZ code, and at all times keeping track of the exact source location of each object. Thereby, when a user drags an element to a new position, the app can override just the numbers in the coordinate without changing anything else in the code (such as line breaks or indentation).This approach essentially required reimplementing a large fraction of TikZ, which is the kind of task that no human would ever want to do. I think building software that doesn’t exist yet because it would be impossibly tedious to code up is one of the great new possibilities thanks to coding agents, and it’s worth brainstorming for other examples. (This app was built almost entirely by Codex.)Implementing the app came with lots of fun side quests, including building converters from SVG &#x2F; pptx &#x2F; ipe to TikZ, re-implementing the LaTeX hyphenation and line-breaking algorithm to support multi-line nodes, and making a color picker that uses the red!20!black color mixing notation used in LaTeX papers.

Each cell is an agentic particle that can move freely in space and change its state.While each particle follows a simple shared rule, many together can grow complex morphologies or form intricate patterns. The resulting particle system as a whole can regenerate from damage and exhibits surprising emergent behavior.Try cutting the lizard and watch it heal itself!

Fired by Google for creating the Google workspace CLI

Shumai is an open source platform for uploading creative files, managing projects, collecting precise feedback, sharing work, and collaborating with AI agents, all in one simple creative-first workspace.I’ve always liked the product design of Frame.io, and I wanted to build an alternative that feels just as polished, while being open source and easy to self host.You can deploy Shumai with docker compose in just a few minutes. It can also be installed from npm, though you&#x27;ll need to provide your own PostgreSQL instance with the pgvector extension installed.For larger deployments, Shumai supports distributed processing via Temporal, allowing resource intensive tasks such as transcoding to be scaled independently.It&#x27;s still early in development, feel free to try and share any feedback.Demo: <a href="https:&#x2F;&#x2F;staging.shumai.one" rel="nofollow">https:&#x2F;&#x2F;staging.shumai.one</a>
