Trump is a famous teetotaler so I'd be skeptical there. When I started getting worried about Elon around 2018 the drugs were part of it but also the persistent sleep deprivation. But there's also the way his father went a bit cra

Some of the Kuiper groups are going to be put at 600+ km which does make me a bit nervous regarding potential debris.

There are a lot of dimensions to what you could call performance. The FPGA here is only clocked at 100 MHz and there's no way you're going to get the same throughput with it as you would on a conventional processor, especially if

Also a fairly interesting Haskell efforts. https://mn416.github.io/reduceron-project/ These range from a few instructions to accelerate certain operations, to marking memory for the garbage collector, to much deeper ef

I guess I'm showing how long it's been since I was a student of Haskell then. Glad to see the addition!

I feel like Haskell really missed a trick by having $ not go the other way, though it's trivial to make your own symbol that goes the other way.

Relatively early but there was at least 500 million and perhaps over a billion years separating the first life and the first photosynthesis. At least as much time as between us and the Cambrian Explosion. https://en.wikipedia.or

Life on Earth was dependent on chemosythesis for the better part of a billion years before photosynthesis was developed. Photosynthesis is really very complex so I think we can rule that out as an initial form of life. Hydrothermal vents a

And, then in theory, restoring the thread when the requested registers become available. But is the spilling/restoring registers hardware something that would see much other use? In some code hardware accelerated stack management can

We've got 10ms of latency between our brains and our hands along our nerve fibers and we function all right.

The second article I ever submitted to Hacker News back in 2011 was on AMD's efforts to build a CUDA competitor[1]. I don't think it's lack of foresight. [1] https://www.semiaccurate.com/2011/06/22&#

The cities are cherry picked but the routes aren't, except for avoiding highways. You can go to any address and that means sometimes having to avoid, e.g., chickens on the road.

Yes, they're driving passengers in actual cities and have been for years.

Long, long ago the the Kinect came out and it was able to provide 3D imaging for robotics companies at an incredibly good pricepoint compared to everything that came before it. Then the company that made it created a version with just the

If a future totalitarian government wants to save money on medical treatments then they can just euthanize anyone who gets cancer rather than euthanizing anyone whose genes say that they have a 50%+ greater risk than average of getting canc

The government can just run the tests themselves in that case. I think people will resist coercive sterilization more than coercive genetic testing.

The EV6 is the other car I've been thinking about, actually. I'm going to need to test-drive both some weekend we're not busy with the work on the new house.

I've found that refactoring to fix a lack of abstraction is usually easier than refactoring to fix the wrong abstraction.

The concept of Don't Repeat Yourself and the concept of You Ain't Gonna Need It are the yin and yang of software development.

When a robot is moving itself it has a very good idea of what each part of itself weighs, how big it is, and has sensors to tell it what angle all its joints are at. These are all much more difficult with an object the robot is holding in

I think the author probably made a mistake in using that subheading. For those familiar with the meme[1] it's saying that this isn't that important but read straight it says the opposite. I'm all for playful subheadings, I

There's not need for an explicit copy, but physically does the data move from the CPU cache to RAM to the GPU cache or does it stay on the chip?

by Symmetry 2y ago
Having a system level cache for low latency transfer of data between CPU and GPU could be very compelling for some applications even if the overall GPU power is lower than a dedicated card. That doesn't seem to be the case here, thoug

I was evidently unclear. I mean, if an image of a parakeet is flashed up on a screen for 100ms and you can say "I saw a parakeet" you were conscious of the image. If the image is flashed for 50 ms and you can't you weren&#x

There's a whole scientific study of consciousness that actually comes out of behaviorism. The thought is, if I have a conscious experience I can then exhibit the behavior of talking about it. From this developed a whole paradigm of i

That's fine for wheeled robots or robots bolted to the floor but for legged robots, especially bipeds, the hard question is how to prevent them from falling over on things. These don't look heavy enough to be too dangerous for a

Oh certainly. And many fewer potentially dangerous complex corner cases than C++ brings.
