I really fail to see a problem with these tiny amounts of non-brittle material embedded into a solid case. It's still very dangerous, but it's locally dangerous (meters away), not at the scale of whole countries.

I found the specs for the fuel source: https://upload.wikimedia.org/wikipedia/en/e/e9/SNAP-19C_Moun...

The high-power unit had 300 grams of Pu-238 in 1965. Given its 87.7 years half-life, only 187g of Pu-238 remaining. It's very hard to do much damage with this amount of radioactive material.

> that (checks notes) has the potential to poison most of North India.

How large is the amount of plutonium in there? I highly doubt that it has the claimed potential.

I am usually running Claude Code in tmux on a Mac. Absolutely zero scroll issues (but I use tmux scroll for that, naturally). It's a delight.

Apple raised iPad Pro prices in 2017 by $50 to address NAND memory chips price hikes from the vendors: https://www.cnbc.com/2017/09/13/ipad-pro-price-increase.html

Quilter is a real deal. Hopefully, open source catches up at some point. But for now, it's Quilter or a lot of manual work & more design iterations.

Yeah, this company (GeneralistAI) is, in my opinion, the most advanced robotics+AI company in the world. Slightly behind them Google DeepMind Robotics and Physical Intelligence, and then the rest.

In the meantime, China is constructing nuclear cargo ships ([1], [2]) that will be able to transport 14,000 containers at full throttle (200MW) without a need to refuel for years.

Obviously, it's still not done, and yet to prove to be profitable, but their reactor design does suggest that they have a chance to make it work and replace a lot of CO2 emissions.

I refer to the RDNA4 instruction set manual ([1]), page 90, Table 41. WMMA Instructions.

They support FP8/BF8 with F32 accumulate and also IU4 with I32 accumulate. The max matrix size is 16x16. For comparison, NVIDIA Blackwell GB200 supports matrices up to 256x32 for FP8 and 256x96 for NVFP4.

This matters for overall throughput, as feeding a bigger matrix unit is actually cheaper in terms of memory bandwidth, as the number of FLOPs grows O(n^2) when increasing the size of a systolic array, while the number of inputs/outputs as O(n).

> This sounds like a happy ending for the employees of Windsurf and a good deal for Cognition

The employees were robbed from having a big cash exit. Illiquid stock options from Windsurf were converted to illiquid stock options of Devin.

What's worse is that the well is now poisoned. I would advise against joining startups from now on, because I think that there's no upside for employees anymore.

Not only they do not release models/weights. They don't even tell the size of the models!

The linked whitepaper is pretty useless, and I am saying as a big fan of diffusion-transformers-for-not-just-images-or-videos approach.

Also, Gemini Diffusion ([1]) is way better at coding than Mercury offering.

This is just a fake product page to gauge interest.

From their "order" page:

> UPERFECT Omega is currently in the concept stage and will soon be put into research and development.
