Until seeing that, I never understood why people go through such effort to see it from the path of totality strip. It's a religious experience.

> Total Eclipse of the Sun. I personally enjoy Trouvelot’s added artistic flair (or flare, if you want to be punny) on this one. The sketch there is actually more accurate than the photo! The flare (corona) is real. Cameras have a hard

I just signed up for TMobile last month. They asked me for my SSN. I said seriously?? They said yes we need it for a credit check to see if we can offer you service. I said sure... it's 123456789. "One moment sir..." "Co

Last time I looked at hydrogen-electric, a huge limitation was the lifetime of the electrolyzer membrane. They are expensive and you have to replace regularly.

Quite a coincidence... Robert Noyce invented the first monolithic integrated circuit chip at Fairchild Semiconductor in 1959.

Actually the most remarkable thing you find is how _little_ structure you need to get evolution algorithms to work. I've thrown together random structures with feedback that are inherently nonlinear and chaotic, and evolutionary algori

I know ground lasers can be used to blind satellites, but I've never heard of a successful test or even a back of the envelope calculation that shows one could be destroyed. Do you have a reference?

A single neural network with 8 bit weights and 1M parameters has 256^1000000 possibilities by that logic, but we can train it fine with simple evolutionary algorithms like SPSA (Simultaneous perturbation stochastic approximation) E.g., ht

If individual missiles are used to take Starlink satellites down, it would be quite an expensive affair. Probably should save those missiles in a war for something else.

Is the problem not so much the testing, but that most current treatments for cancers are so crude? If you have a relatively asymptomatic cancer, the treatments (chemo, surgery, proton beams) and psychological stress of discovery could be w

200Hz seems a low enough frequency (1.7m wavelength) that they could do active noise cancellation with a small onboard speaker designed to generate a similar sound 180 deg out of phase such that it cancels in far field. Would probably need

Doesn't everyone do this? I remember at the age of five finally learning to control my falling dreams at night, to be able to freeze in the air and eventually fly (the Matrix scene definitely resonated later). This was the beginning of

Are we seeing the formation of new arches at a similar rate? It seems we must.

I good reminder to test your home for Radon. Check your local Radon maps, there are hot spots throughout the world that vary locally. Even if maps show low values it is worth testing.

This is compressing video recordings of a computer desktop. The frames don't change much so this isn't surprising.

Yes, re-entry can survive for the lower velocity orbits all the way to ground depending on debris material and orientation. Air density is 20% at 40k ft, so much more likely to make it that far.

Just a rocket booster reentering? These happen regularly especially now that launches are more frequent in US and China. It seems to match up with https://aerospace.org/reentries/cz-11-rocket-body-id-46463

Starlink today slightly beats my Comcast performance-- both up and down. Starlink costs a bit more, but the service, bandwidth, latency is getting better every week--I'd rather be hitched to a modern company that knows how to improve.

This still requires an antenna tuned to the appropriate wavelength, and for matching you cannot have all antennas connected at the same time, they must be switched, so this would be unable to receive all frequencies at the same time. The pa

Right, if they are using standard OTN framing, the hop latency should be ~3 microsecond (which is <1km of light propogation)

I do enjoy driving down country roads which won't have superchargers for some time, but these trips are usually <300-500miles and by it's nature the route is flexible enough to hit a supercharger near a highway if necessary.

Will be watching for the success of Rivian and Cybertruck to see if the rural market can accept electric.. but can't think of any good reason why not, other than pride and prejudice. (FD, I grew up in the country).

> This course examines papers every computer scientist should have read, from the 1930s to the present. But the latest paper listed is from 1986. Has there really been no fundamental CS progress in ~four decades?

You could spend ten minutes debating whether the growing bright light and rising Doppler sound exactly matches the expected profile of an oncoming train.. or you could just get off the tracks. Here absolute fact is only clear when the effec
