I can’t think of any reason why it would be impossible to implement skeletal animation of gaussian splats. You still have to create the splats from images though. Just have your subject put their right arm in, then take your images and gene

It’s easy but a bit data intensive. Take two 3D splat images at different times, optimize them, then interpolate from the first to the second. Repeat at intervals. Now you have a video. A full moving subject is about 500Mbps, although it de

The flesh of the strawberry is very slightly translucent. By taking images from many angles, you can derive some information about the interior. This is not a separate step, it is simply the optimizer finding splats that contribute the righ

Several times I have heard you express your frustration that real life was copying your books too closely. I can understand that since your books always seem to be rather cautionary if not outright horror. But I always wondered if you’ve ev

Almost. It should be (+ a (apply #'+ b)). Common Lisp is a Lisp-2, so a + in the argument position is assumed to be a variable named +, not the function named +, unless you specify otherwise.

That’s what Common Lisp is.

That’s because the lobsters were an AI using an LLM to communicate. All we have is the LLM.

Mostly just invented things, patented them, then brokered the deal, often donating the patents to the Open Patent Foundation in the process so that nobody could monopolize the idea in the medium term. For example, he patented the idea of us

Here in datacenters we use cooling systems to move heat away from the computers and out of the building. If each rack in the data center were outdoors and 100 yards away from every other then almost no cooling would be required. Just some f

You’re way overestimating the size of the radiators needed. Then you overestimate their mass, because the ISS has huge heavy radiators that operate at <30°C. A rack of computers can run at much higher temperatures and therefore need much

I think you’re overstating the problem. All of the tests flown so far were deliberately crippled just to see how much they could get away with. They installed fewer tiles than were really needed, leaving gaps in large surfaces and even leav

The radiators would be a lot smaller than you’d think: < https://www.youtube.com/watch?v=FlQYU3m1e80 >.

If you gather 1kW of power from the sun then you have to reject 1kW of heat once you are done with whatever computation you are doing. There’s a bit more heat absorbed from the environment since some sunlight strikes parts of your satellite

It’s very easy to overestimate the difficulty of cooling things in space, unless you actually run the numbers. So please follow along as Scott Manley runs the numbers: < https://www.youtube.com/watch?v=FlQYU3m1e80 >. Ba

That’s all irrelevant. The government cannot take unconstitutional actions even if they think it is good policy.

Doing what is easiest often causes suboptimal results. In this case people hopping from one inadequate tool to the next, instead of sticking with one tool for a long time and slowly improving it any time an inadequacy is discovered.

It's fairly obvious that people who write articles like this don't really care whether the orchestra is any good or not. To them it is more important that the orchestra meet their arbitrary racial and gender quotas. Of course it’s

I regard that as a downstream effect of giving power a unit in the first place, but yes. We should have just stuck to J and J/s. It would have prevented the kWh and also abominations like the mAh “capacity” ratings you see on batteries

Using watts is fine for anyone who deals with energy and power all the time. The problem comes when the lay person tries to reason about power. If power were written as J/s then they could use the same reasoning that they are already f

by db48x 6mo ago
Don’t put words in my mouth. I only said that power should be J/s instead of watts. The “per second” part of that is what is most important thing about power. It’s the rate at which energy is accumulating or being used up.
180.
by db48x 6mo ago
It doesn't. Watts were a mistake by whatever committee it was that standardized unit names. Power should not have been given a unit; it should have been left as ∆energy/time just as velocity is distance/time.
