Trademark are always about use in a particular context. Apple has a a trademark on computers using the name "Apple" even though that's been a word for a food for centuries. And if you want produce a line of bulldozers and b

They're promising they'll ship by the end of the year at the latest. Again, I pre-ordered but I'm also thinking that if the PC thing sucks at least I'll finally have a plugin VR headset that actually fits my head. Go a

SimulaVR markets themselves as a productivity VR headset. Essentially, have as many terminals and other windows as you want floating in the air around you while still having the pass through cameras to see around them. The review copies a

Assuming that bytes are 8 bits long or that negative numbers are represented with two's complement is a lot less dangerous these days than it was when C came along.

I haven't had a chance to play with comptime in Zig yet but I'm sort of curious how it compares to Nim's compile time facilities. You can declare variables with 'var' for true variables, 'let' for things

That's a common misconception and I'm not surprised it made it into Wikipedia. Moore's 1965 paper was the first time anybody had pointed out the exponential nature of progress in miniaturizing transistors and packing more of

The idea is that if you build a system that poses an existential risk you want to be reasonably sure it's safe before you turn it on, not afterwards. It would have been irresponsible for the scientists at Los Alamost to do the math on

I dunno, a quarter meter sandwich seems just as natural as a quarter pound burger.

That might be why Sam Altman signed it but why do you think that all the academics did so as well. Do you think he just bribed them all or something?

There's a lot to be said for open source ISAs like RISC-V. But it's a lot harder to create a top of the line open source microarchitecture implementing it that's competitive to closed source designs. A Linux kernel develope

Because the energy lost to the movement of the propellant goes up as the square of the velocity but the thrust goes up linearly. Bulking out your propellant by a factor of ten while reducing the exhaust velocity by a factor of ten doesn&#x

To get a turborocket to work in an atmosphere without oxygen you just have a classic rocket engine, with its own fuel and oxidizer, use its exhaust to drive a turbine the same way a jet is used to drive a turbojet. You have to leave off th

You'd certainly need something beyond a chemical rocket but there are options. At that density a turborocket[1] would certainly be worth the extra mass but I think still wouldn't be enough of an advantage. In the realm of roughl

It's close equivalent. It's easier to go inwards than outwards in terms of delta-v because orbits further out move more slowly. So if things were a little different the orbit of Mars could have been closer to Earth in terms of di

The numbers for reaching LEO include typical atmospheric drag losses. That's only a km/s or so on Earth but on Venus with it's very thick atmosphere the losses are much higher.

Which planet happens to be the closest to us right now is the metric most congruent to people's notion of closest and is often important for things like time delays in radio communication. By that metric it's currently Mercury, c

Surely not that much. The LD50 of heavy water is really high at 30% of body weight[1] but it's only about $10,000 per kg. So even the most obese millionaire should be able to kill themselves this way if they really want to. That&#x27

The original "Copenhagen Interpretation of Ethics" blog post: https://web.archive.org/web/20220705105128/https://blog.jaib... It's nice to have a handy phrase for this effect.

It doesn't very much, in theory. Figuring out the instruction boundaries in x86 instructions in parallel is rather involved but after code has been seen once the boundaries can be marked with an extra bit in the L1 instruction cache a

Parts of it reminded me of the Cell too.

Also, thanks to the thin atmosphere and lack of a magnetic field Mars's surface is about 50 times more radioactive than the Earth's, but it's still no as bad as space out past the Van Allen belts

The FPU/memory interleaving reminds me of ARM's Helium instructions. Which makes sense given the flock of chickens approach. It's great to see people developing practical architectural innovations for their own use cases li

I sort of wonder if it wouldn't be best to auction off the new visas to companies rather than assign them by lottery. Then they go to the companies their most valuable to and the government gets some revenue.

In terms of deciding how careful to be about it. An interesting property of Covid is that getting it for the first time without vaccination is about the equivalent of a typical person's full actuarial Micromort budget for a year regar

When I was growing up hearing about "fallout" was always in terms of some power plant accident and exposure meant some imperceptible increase in lifetime cancer risk. Much later in life I learned that the "fallout" from

I dunno, I use it all the time. Putting the danger of Covid-19 into micromort terms was a useful exercise for instance.

Our hunter gatherer ancestors living in bands suffered from drastically fewer respiratory diseases than we do, you need a large connected population for something like the flu to survive in a human population in the long term. The issue wi

Right. I sort of worry that because LLMs are able to be so coherent without anything resembling a human's working memory at all, then adding either a crude working memory still working with LLM tokens or adding a more sophisticated on

Better to say, I think, that humans are much better at improving their approximation of consistency with mental effort both because we can think silently instead of "out loud, step by step" and because some of the patterns of care
