This is one of the best engineering blogs you'll ever read.

Not *just* because you'll learn a lot, but because @vmg sprinkles in a bit of everything.

A great story. History of git infrastructure. Distributed systems. Benchmarks. All written by someone who can speak to every point from deep, personal experience.

It's also 5,300 words, so grab a drink and enjoy.

Most underwater robots still rely on propellers.

That works well for speed, not for control.

C-Ray takes a different route.

Instead of rigid thrusters, it uses flexible hyperbolic fins that create thrust through body-like waves. The same mechanism lets it:

• swim like a ray
• crawl across the seabed
• jet forward when needed
• slide through tight spaces

The benefit is not just motion variety.

The undulating drive is quiet, energy-efficient, and far less disruptive to the environment.

That makes it useful for long missions like reef surveys, infrastructure inspection, or mine countermeasures, where low noise and low power matter more than top speed.

🧵 Farming robots are no longer experimental. They're deployed, profitable, and reshaping agriculture.

In orchards, vineyards, vegetable fields, and beyond, they're tackling labor shortages, precision spraying, and chemical reduction at scale.

This is how robotics is quietly becoming the backbone of next-gen agriculture

Water can solve differential equations.

Lukyanov, a Soviet engineer, was trying to calculate heat transfer in concrete structures.

Hand calculation was cumbersome, so he developed an analog computer to physically model the math relationships.

It worked *really* well.

Say hello to one of our Milky Way’s neighbors! 👋

DESI has made the largest 3D map of our Universe to date

Earth is at the center in this animation, each blue point is a galaxy: > 14 million galaxies in total up to 11 billion light years away

The gaps are the regions where our own galaxy blocks the view

I wrote up all my thoughts on whether NVDA stock is finally a decent short (or at least not a good thing to own at this point). I’m a huge bull when it comes to the power and potential of AI, but there are just too many forces arrayed against them to sustain supernormal profits.

HOW TO DESIGN A FACTORY

Lots of talk these days about bringing back manufacturing to America. In light of that trend I've decided to give you a how-to-guide on designing a factory

[Michael Hla @hla_michael]

I taught an LLM to optimize proteins. It proposed a better carbon capture enzyme.

Introducing Pro-1, an 8b param reasoning model trained using GRPO towards a physics based reward function for protein stability.

It takes in a protein sequence + text description + previous experimental results, reasons over the information given in natural language, and proposes modifications to improve the stability of the given sequence.

Since Chain Replication with Apportioned Queries (CRAQ) is in the news because of DeepSeek 3FS, it's a good time to revisit the MIT 6.824 FAQ on the paper.

“Entropy is geometry. And geometry is entropy.” This is a new finding by Gabriele Carcassi, and I'll explain the reasoning below, along with the math. Don't worry, I'll hold your hand (metaphorically, of course, unless you're into that). (1/19)

The spell article reached Douglas. I saw him subscribe but thought it might be a prank by someone, until I saw this email from him. Very grateful that he took the time to read and respond to it.

PS: I fixed the mistake he pointed out.

Distributed training is notoriously hard to learn - knowledge is scattered across papers and complex codebases.

Enter picotron: implementing all 4D parallelism concepts in separate, readable files totaling just 1988 LoC!

[Charles 🎉 Frye @charles_irl]

I think programming GPUs is too hard. Part of the problem is sprawling, scattered documentation & best practices.

Over the past few months, we’ve been working to solve that problem, putting together a “Rosetta Stone” GPU Glossary.

And now it’s live!

My take-aways in thread.

We needed a vector database that was inherently “Cloudflare”: deployed globally, distributed, and intrinsically multi-tenant.
