U-234 is ~3000x less radioactive than Pu-238, so having ~120g of U-234 is negligible.

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.

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.

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.

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.

krasin — Sun, 14 Sep 2025 02:28:06 +0000

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).

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.

Quote from the article:

>With these innovations, the team fabricated a 1.09 cm2 flexible monolithic perovskite/CIGS tandem solar cell. Competing with top rigid counterparts, the device achieved an impressive stabilized efficiency of 24.6% (certified at 23.8%), one of the highest reported values for flexible thin-film solar cells to date.

>After 320 hours of operation and 3,000 bending cycles at a radius of 1 cm, the device retained over 90% of its initial efficiency, demonstrating exceptional mechanical durability and long-term stability.

I always recommend quilter.ai: https://www.quilter.ai/ - they "eat" Kicad or Altium files, and produce autorouting and/or autoplacement. I tried them about 9 months ago and made a couple of boards that worked well.

They seem to be showing very decent performance results for diffusion transformers. Not so much for the autoregressive transformers (the "regular" ones).

DeepSeek R1 has 671B parameters. If you want to run at 8 bits/parameter (the native format for DeepSeek R1, in which it was trained, so the top performance possible for the model), one would need about 32 Blackhole p150a ([1]), which is around $42k and 10kW power consumption.

So, yes, you can run DeepSeek R1 on it, but there are cheaper options (if we only talk about inference).

It's far from the first generation. Unitree has been selling robot dogs for over 6 years now and I remember them being a lot less refined. See, for example, what Unitree was selling in 2019: https://www.youtube.com/watch?v=FFJUkrCQzx8

They just need a few more iterations.
