I think you're missing that the source of the data is social media posts. So garbage data in, garbage data out.

Someone else had a similar issue 6 years ago https://electronics.stackexchange.com/questions/334012/hsi-a... It sounds like the sampling clock frequency is not what is expected (but that's quite easy to check

There's some dodgy maths >( 100 / 157,075,200 ) * 1,000,000 = $0.000000636637738 Should be $0.64 so still expensive

That may be the reason for sudden traffic jams but it isn't the reason for traffic in general. Leaving more distance reduces throughput and necessarily creates congestion further back.

A good explanation is that freeways behave like superheated water in that they are somewhat bistable. Just like water can be above 100C without boiling when there are no impurities, freeways can transport more traffic throughput than satura

It's a nice idea but surely any variation in mass of the lightsail will result in significant forces which will literally pull the sail apart. And with a thickness of 100 atoms that variation might be just a few atoms. I can't see

Can't see this as being particularly useful. Libraries under active development will have larger more frequent releases (but small number of libyears out of date) whereas mature software with only occasional bug fixes may be 10s of lib

The paper [0] contains the key number: average power of 3.6 μW so enough to power the lowest power electronics but not much more. [0] https://www.cell.com/device/fulltext/S2666-9986(24)00108-X

Yes airplanes have to travel faster (in terms of ground speed) to not stall. This is why head winds are preferred for landings and take offs as it allows ground speed to be lower. But during cruise you want a tailwind to reduce the amount o

This seems like a lot of effort to get a net list given other techniques to deduce what pads are connected (e.g. knowing the most connected net is the ground plane, looking up the pinouts for the ICs, looking at the voltages and signals wh

Connected to the grid yes but usually the interconnect is simply enough for running the mine not enough to cover many megawatts of storage capability. The battery storage companies have found that there is an abundance of fields and brownfi

This must be orders of magnitude more expensive than pumped hydro and I would expect more expensive than lithium batteries. And unless the mine is close to an existing high voltage substation then there will be significant costs hooking it

I suspect that this patch https://w1.fi/cgit/hostap/commit/?id=b0f457b6191aa8ee329331c... may fix the issue although the default key lifetime is 12 hours not 11 but maybe there is something which runs every h

The energy is something like 100 tonnes of TNT so a big bang but not catastrophic to the planet.

With a big enough laser and a big enough collecting device for a reflected signal, I can imagine that communication even at such distances is possible. On the other hand I can't understand the propulsion mechanism. The acceleration is

A little bit old but I think this video https://vimeo.com/180284417 nicely demonstrates how a quantum computer compares to a classical computer and shows how limited the hardware is (although it has advanced slightly since

It's the same for wireless protocols too. Transmitting with less bits per symbol makes the whole packet longer and potentially more prone to interference. Transmitting at a higher symbol rate can often reduce the amount of packets lost

A disappointing ending to the tale. I really want to know how Grammarly desktop works now. It must have interfered with the Chrome process in some bad way.

Hardly at all, video decoding isn't parallelisable. It's often lumped in with the GPU but it is significantly different.

The numbers suggest a ~1000:1 reduction in scale so a 1000x optical microscope should be more than sufficient. But finding the information you are searching for at that scale sounds difficult unless pages are indexed and numbered in both th

At least generate some sizeable mock data before showing the query plans. The optimisations applied can be very different depending on the number of rows in each table.

Definitely vessels of some kind. I think the author overstates the brightness which is hard to judge in such dark conditions

So I can understand how having a phase change causes the material to have a critical temperature but why does it also have a critical current and a critical magnetic field. A simple phase change material wouldn't have a variable critic

by barbegal 3y ago
That would be my interpretation too. Usually you get a stronger transition to 0 at the critical temperature but I can't see this (although it could be hidden under the noise)

This doesn't look superconducting at all to me, simply the sample is very small and below 110K the resistance of the sample is too small to be measured by their measurement equipment. I'm happy to be proved wrong but there should

The pressure simply removes all air bubbles. To make blue ice you simply need a very long ice cube with no bubbles such that the red and green light is absorbed but not blue. I guess you could freeze a 10m long tube and look at the ends
