Every step taken by the nonprofit leadership has to be, (or at least seem to be at the time), net positive for the stated goal of the nonprofit. To be legal, the IPO needs to be a net gain for the nonprofit. It can easily be that, if they b

We are very, very far from thermodynamic limits. Lots of people have done the math, and current-gen systems use ~1000000000x more power than the Landauer limit, and ~100000x more power than ideal digital implementation on existing CMOS. Cur

Also in 2021, Nauka (the cursed Russian module) arrived on the station, and accidentally fired thrusters while attached, fighting against the attitude control of the station, flipping it around 540 degrees and putting a lot of stress that t

I don't think it would help. It's not just a software issue that can be fixed in the kernel, the hardware fundamentally isn't part of the cache coherency system of the CPU.

Typical desktop GPU ram does not support being write-back cached by the CPU. With PCIe resizable BAR, you could map the area into ram, so you could technically fit 32GB to memory, but it would have to be uncached (or write-combine cached),

It's not as feature rich, but has also not crashed once for me, unlike gemini cli, which was a flickery, unstable mess.

Google trashed the Gemini CLI client and replaced it with agy (antigravity), which is written in go and is much nicer.

If the latter is 10x faster, the issue is some kind of weird compilation failure for the above version. For one, it only cuts a third of the multiplies.

FP Division by constant is optimized by a compiler into a multiply. Graphics processing typically happens on the GPU these days, and on all recent GPUs FPMUL belongs to the class of lowest-latency operations. That is, there are no other ins

I honestly didn't expect the ranges to be ever fixed, I just expected they would remain as an eternal wart. I wonder how painless the transition will be.

It's not a big secret. If you just do the math yourself, it's easy to compute that inference doesn't cost all that much. People just see all the capital investment going around and all the new data centers being built, see th

That doesn't matter for the legal requirements. The short and only kind of wrong version is: In the US, companies are not allowed to unfairly privilege some investors over others by giving them access to secret information that would l

The key AI labs are not public companies, they are at liberty to brag about their margins to potential investors in private.

Why on earth would AI labs be bragging about how little the product they sell actually costs them to make? You don't want to do anything that reduces it's perceived value to the user, that might make them less willing to pay for i

However, there are markets where you don't have to fly supersonic over land, the distance is long enough for the speed to matter, and there is massive amount of demand. The only problem is, such markets require a longer range than what

Building new capacity takes years. The idea is that the market is reliably cyclical, so you should expand when there is a downturn, when costs are low and you can afford the short-term capacity hits that expansion causes (fe. when you divid

Not just charge a small battery and discharge it 3 months later, but to store 3 months worth of production. And using batteries, the cost of that is currently bonkers. The lowest cost large-scale BESS projects that have been completed are i

In a lot of places in the world, the marginal cost of electricity is zero, if your capital costs are low enough to only purchase when there is excess wind. The cost of batteries for long-term storage is still prohibitively high. In contrast
