Thank you. I indeed fell for Apple marketing.

Apple is using HBM2 ([1]) memory, pioneered by AMD for their GPUs. Essentially, yes - it's that, placing memory really close to compute and making a lot of channels for higher bandwidth. 1. https://en.wikipedia.org/wiki

Cooling a gigawatt-class reactor like that? - not a chance A 10kW reactor - easily; a very limited amount of engineering to design a heat distribution system will be required, but 10kW is also not enough for anything useful. I suppose the f

Thanks! I now get the reference, although it was completely accidental. I should watch the movie, I guess.

Under the layer of regolith, Moon crust is mostly basalt ([1]), which has about 1.6 W/mK thermal conductivity ([2]). Not great, not terrible. We all know how cold it is to stand on a stone floor - unlike wood or plastics, it keeps suc

Heat will be an asset, not a problem: the Moon sub-surface temperature is around -20C ([1]), which means there's an easy way to dissipate power. And if we have any humans living on the moon, that heat will very much be appreciated arou

+1 to Framework. I self-repaired my kid's laptop twice (spills; once I had to swap the keyboard, and another time - motherboard), and it's being straightforward to fix.

Open source FPGA toolchains begin to appear, mostly on the low-end for now. And because all FPGA vendors are doing such a terrible job for tooling, Yosys and friends are likely the future.

TinyTapeout ( https://tinytapeout.com/ ) is fantastic. I submitted three simple designs: one as a part of TinyTapeout 1, and a couple more in TinyTapeout 2, and now waiting for physical chips mounted on a debug board to arriv

Public land must be made accessible to the public. And the owners of the private land must maintain the public access road. Otherwise, we will get more inaccessible public beaches, like Vinod Khosla is currently holding hostage: https:&#x2

I work in a robotics research group. My natural bias is to always praise the robots. If the goal is just to have N robots/rovers on the moon for fun/data collection, then we don't need to send humans to space. If the goal is

Thank you! You're right, this is not about a Mersenne prime, but about Repunit prime. Sorry about that!

Edit: the OP is correct, I was confused by the forum name, as I thought it was about Mersenne primes, but this is about Repunit primes. Original response: Almost correct, but it's 2^49081-1, not (10^49081-1)/9. And there's no

Good luck with your launch and the mission. Is there a way for us to follow it?

Fascinating story! But yes - the mathematical beauty of a planned economy model is often negated by sheer incompetence and corruption of the planner.

One of the best minds of that epoch that worked on the problem was Leonid Kantorovich ([1]). From wikipedia: "He is regarded as the founder of linear programming. He was the winner of the Stalin Prize in 1949 and the Nobel Memorial Pri

They are entitled for attention, yes. And if they respond to code review and ready to address comments, they will likely get it merged (depends on the project and the PR, obviously). The requirement to be a member of a collective is a filte
