It's kind of fascinating to me that two of the prime obsessions of the 21st century science are "meat without mind" and "mind without meat"
If people want to do this, we need to learn how to make a bunch of enzymes at scale and it may actually not be possible for cheaper than real meat for a long time
I think what is going to happen is that lab-grown meat will gradually catch up with real animals and when that happens we will all quietly admit that the vegans were right about factory farming

Impressive as that sounds, thermal engineering has lagged behind transistor density improvements.
Thermal envelopes significantly cap current chip performance.
Any "breakthrough" in cooling technology (think microfluidics) will have disproportionally large effects on human progress.

It took immense persistence to turn the initial hunch, that an attention mechanism could model long-range interactions in light transport, into a robust, working system. Huge congrats to the entire team! 🎉

🎄 Introducing our paper A Generalizable Light Transport 3D Embedding for Global Illumination lnkd.in/gQUMSAyV .
🙈 Just as Transformers learn long-range relationships between words or pixels, our new paper shows they can also learn how light interacts and bounces around a 3D scene.

This feels very true. With copilot I kinda want a sub-PR mode (that it doesn't have). I want it to create a tiny change, show it to me as a difference, chat with me about it, iterate. Then at some point I'd accept it, and commit.
This granularity doesn't exist, sadly. Either tab-complete, or a PR

Andrej Karpathy’s take on AI coding agents feels grounded. The industry’s chasing full autonomy when models still hallucinate too much.
Agents that churn out a thousand lines of code leave you either blindly trusting them or slogging through reviews. These tools should embrace their fallibility.

I can't* fathom why the top picture, and not the bottom picture, is the standard diagram for an autoencoder.
The whole idea of an autoencoder is that you complete a round trip and seek cycle consistency—why lay out the network linearly?

I really don't need my task tracking and productivity apps to feel like a Gatcha game tyvm
New pet peeve: lots of apps are free to download with some features behind a paywall. I don’t begrudge that; it’s a legit business model. HOWEVER — the trend of late seems to be NOT having a webpage describing which features are behind said wall. I don’t like mystery! Just tell me what's not free!

The framing of this entire article makes it sound like a benevolent AI independently made these drugs.
