I'll be in Berlin for @localfirstconf.com next week. Do I know anyone who will be there?

There was one story on stackoverflow where someone's C code was faster than their hand crafted assembly and now it is generally believed that high-level abstractions generate higher quality output.

Figma expands to build pretty much anything Slack integrates claude so you cand build directly from there Notion adds more AI to to make anything Linear integrates AI and git so you can build directly from there.

I made an online demo of the WebGL Flex Avatars! it took some work to pack everything so that it can run online but I managed to fit the gaussian model, 10 expressions & the mesh proxy in 16Mo :) I also added Gaussian relighting and shadow casting, audio playback and a webcam to drive the avatar 🔗 👇️

Alternating between multiple agents gives me Overcooked vibes

People talk about how claude + slack is a match made in heaven. This is not the future of my dreams. I want to see "Microsoft Bob meets Google Wave"

Early concept videos like Apple's Knowledge Navigator (1987) are a fascinating reflection on the future we wanted. www.youtube.com/watch?v=For...

I managed to get FlexAvatar to run fully in browser with ONNX WebGPU ! 🎉 since inference is now rea-ltime, it's running fairly fast (20-40fps) so I added an audio analysis tool to make the various expressions reactive to sound 📢

The worst thing that happened to me last week is that my bicycle chain broke. I feel completely stranded.

the problem with Novel View Synthesis, in a nutshell. ( MV-adapter & SDXL, first image is the input )

Made a thing on my phone

"Game dev is one of those jobs you only do when you really want to. It's not going to make your parents proud, you're unlikely to get rich in an industry that lays off people for making superhits, and its a demanding & confrontative job. Why would you let a machine do the thing you're here to do?"

Letting AI make us idiots is a choice, not a fatality.

uhh… TIL: <marquee direction="down" behavior="alternate"> <marquee behavior="alternate">This text will bounce</marquee> </marquee> developer.mozilla.org/en-US/docs/W...

It's very destabilizing when the AI gives me what I need instead of what I asked for

I want to write some code. With my hands.

I finally made a proper website for Fragment 🎉 Right now, it is mostly a wrapper to the documentation available on GitHub but this is only the beginning! fragment.tools Built on top of @vite.dev, @svelte.dev and Mediabunny by @vanilagy.bsky.social

Forcing function

The malleable software crowd should investigate the rules of Uno. Probably the most malleable thing out there

I know this is controversial and I'm taking a risk saying this, but slack might not be the best communication tool for remote teams

New on Constraint Systems: Sphere Paint Multi-player painting without edge sphere-paint.constraint.systems A sphere is interesting because all points are continuous on all sides. You can respond, extend, or connect in any direction.

It's unfair that AI won't wake up at night thinking about that stupid thing it said 12 years ago

Zero data isn't just a customer perk, it's really for me. We've normalized optimizing all the joy out of our businesses. One way to push back is to not put that weapon in your hand and instead collect no data.

"Velcoity". Perfect typo.

I'm not super worried about the effect of AI on the younger generation. I'm confident that there will always be adventurous and ambitious people who will want to do great things. These people will use whatever tools they have, including AI, in a smart way.

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

All 2D editors become 3D editors at some point All 3D editors become 2D editors at some point

chiral aperiodic monotiles go brrr

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.

New blog post: A Decade of Slug This talks about the evolution of the Slug font rendering algorithm, and it includes an exciting announcement: The patent has been dedicated to the public domain. terathon.com/blog/decade-...

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 🫶
