You might remember that I was working on my own programming language a few months ago. I've decided to write a blog post about what this language is, how it is implemented, and what are my future plans! lisyarus.github.io/blog/posts/m...

Still working on my "chain of increasingly complex programming tools". I'm working on V4. One idea for this version is to use the jj graph as the interface to manage the tasks

Clojure is a really fascinating language. I tried to use it seriously on a couple of occasions, but it never completely clicked for me. Despite that, it definitely had a great impact on how I think about code. clojure.org/about/docume...

I've wrote a new post on the math I use to draw procedural roads only using lines and arcs. Here is how the construction unfolds:

I'm late to everything, so I didn't notice the frequent usage of the word "harness" until recently. Apparently it started in november.

One thing I find useful when writing specs for a coding agent is to explicitly define a vocabulary upfront. I don't know if it makes the agent perform better, but it definitely helps write a clearer document.

If, like me, you wake up every morning wondering what the Voronoï diagram of arbitrary shapes looks like, here is the answer:

Github is dying. It won't disappear suddenly, but unless they do major changes soon, it will be like facebook: still here, but we open it less and less. Maybe it will survive as a pure code storage. The replacement is not exactly here, but there are some changes

This morning I'm vibing a chain of increasingly complex programming tools. I'm at V3. V0 was... nothing. Just claude in the terminal V1 was useless beyond any reason. When trying to improve V2 from itself, claude thought it would be great to restart the app, effectively killing the session 🙃

A 2026 version of emacs would be a self-building IDE where you prompt an AI to add modules specialized for the work you are doing.

One thing I learned working on a drawing app is that vector and raster graphics are much more compatible than I thought. Once you have layers, you can perfectly interleave vectors and pixels. Affinity is doing exactly that.

New post released! 🎉 I’m breaking down everything I’ve learned about the push-pull algorithm in Signals. It's an important publication for me, this article required more research and creativity than my previous posts. Enjoy! → willybrauner.com/journal/sign... #signals #frontend #article

After many attempts over years and years, I finally managed to implement Fortune's algorithm for Voronoï diagrams. The step by step visualization was key to debug the process, and when everything work it's just mesmerizing.

JJ turned me from "uh let's delete the whole directory and clone the repo again" to "hey let's rebase these 5 branches at once! Wow, look at how my history is clean now!"

Ok, I'll assume `jj absorb` is just magic. Just used it for the first time and it was perfect

I'm almost there it's so pretty!! 😭 this is the first time I've made extensive use of complex numbers in shader code, which has been fun! it's an analytic 2D lighting system through piecewise conformal maps representing angular light/"sky" exposure, which means you get fully analytic penumbras!

- You are curious about Optimal Transport ? - You'd like to know what is "Semi-Discrete" ? - You'd like to know how it helps computational cosmology ? Short version of the story: github.com/BrunoLevy/Gr... P.S. post-doc position available very soon, stay tuned (or DM me if you can't wait).

Unpopular opinion: The “Premature optimization is the root of all evil” quote has been used more to justify bad designs with terrible performances than to make good tradeoffs.

One more time — I'm looking for new consulting clients. Some ways I can help: ∙ Fractional tech leadership (tackling "leadership debt" in small eng orgs) ∙ Full-stack, 0 to 1 projects ∙ Language design & impl (eg with @ohmjs.org) ∙ JavaScript/TypeScript perf (🔁 appreciated)

After finishing writing clear instructions for Claude, the actual changes feel so trivial that it would be faster to write them myself. Maybe claude is just the rubber duck we've always needed.

reactions to Nvidia's DLSS 5 announcement really made my day 😂 bsky.app/search?q=DLS... thank you internet 🫶

Am I accidentally building a Color OS? :D Different needs require different stats, so I decided to let users rearrange, show, or hide color stats however they want.

First bsky post ever 👋 Just sharing something I’m building

We need trees of PRs in Github.

passing on the good word: "Threejs Conf Paris, here we go ! 🚀 --> threejs.paris Waitlist open !" organized by David Ronai (et al.), already a solid lineup :)

In a HN comment someone used the term "pilot" instead of "author" for AI-generated code. Sounds appropriate.

Ran into some issues with jj workspaces. It seems you have to be careful about what workspace you are in when manipulating the changes graph

Pure talent.

"AI allows me to build things I would never have the time to build before" The things:

I am way less tempted to consult social media and news websites when I reframe them as "the voices in my head"

Been ruminating on this lately as a maker of small one-off things… years back I’d made console.frog github.com/tholman/cons... … prob took a few hours, would take ai 1 minute. It’s not that my enjoyment from executing on an idea is gone, but the way my work is perceived has shifted.

"Order and disorder." probably my last take at #genuary26, uses a 3D pathfinder to go from neatly ordered stacks to a random layout. #genuary2615 BTW, I'm available for freelance work (2 days a week for now). HIRE ME, I'm GOOD (& CHEAP! 😁) also ok with collabs, mentoring, Q&As, AMA...

Friendly reminder that if you're doing #genuary with either 2D canvas, p5.js or three.js, I would love for you to try out Fragment github.com/raphaelameau... #genuary2026 #madewithfragment

Circles, feedback loop

Inigo Quilez wrote multiple "avoiding trigonometry" articles: iquilezles.org/articles/noa... iquilezles.org/articles/sin... iquilezles.org/articles/noa... I remember reading the first one years ago, it completely changed how I think about angles.

Oh, and avoiding trig functions. One acos() made it through, but in general, if you use any trig functions in this, you're doing it wrong and there's almost certainly a better way. That's some algebra I'm glad I didn't have to repeat.

The process of code review we are used to is not really adapted to the new practices involving AI.

A magnetic pendulum simulation, as I've been slowly polishing and moving some @observablehq.com notebooks from the web editor over to blog posts. Observable Notebook Kit is such a joy to use. rreusser.github.io/notebooks/ch...

My personal projects are my escape from reality—each one its own little world that rewards slow, diligent work. I enjoy watching them evolve from nothing or a forgotten something into a brand new thing for others to enjoy. I can’t remember a time when I wasn’t making something and I love it.

There is a floating idea that code quality is not that important, only the final product matters. My experience is that for each developer who thinks like that, you need another one to fix the mess.

Sketching with Math and Quasi Physics kyndinfo.notion.site/Sketching-wi... Reposting to wrap up the year. Humbled to see these materials being used by many more people than I ever expected. Truly grateful for all the support and collaborations through this work. Thanks!

My "No Graphics API" blog post is live! Please repost :) www.sebastianaaltonen.com/blog/no-grap... I spend 1.5 years doing this. Full rewrite last summer and another partial rewrite last month. As Hemingway said: "First draft of everything is always shit".

6 years of thinking I can make a better portfolio. 1 year of actually building it. My new portfolio is LIVE 🚀 Please, don't break anything! 👉 bruno-simon.com

Nice article about css, layout and constraints. pavpanchekha.com/blog/why-css... The idea of constraints always felt more natural fore than whatever css proposes (ok, flexbox is not too bad). When people ditch constraints because they have issues, I'd like to point that css have their issues too.
