The 50GHz or 20ps figure is actually the limit of the gear the scientists had available - from the paper at https://iopscience.iop.org/article/10.1088/1361-6463/ad9284/...

"the signal state transitions were established at less than 20 ps, which is comparable to the bandwidth limit of the oscilloscope utilized at 50 GHz. [...] the initial rise time constant may be shorter than the measurement limits of the oscilloscope."

I got the impression that "faster" refers to potential bandwidth, as the device responds to shorter wavelengths (300nm to 1.6nm) than other photodetectors.

Shorter wavelengths means higher frequencies, "number go up" = more data per second.

This is press release language though, it could mean anything.

That format is really nice!

I regret to say it but I found what looks like a typo - you've got "automcomplete" where I think you mean "autocomplete". I hope this helps improve your resume.

Addressed directly in TFA:

"Drawing out the interview process is a thinly veiled attempt to launder this bias with a "neutral" process that they will likely disregard/overrule if it contradicts their personal preference.

That doesn't mean that I think this sort of interviewing bias is good or acceptable, but I also don't think drawing out the interviewing process corrects for this bias either."

Fortunately the accelerometer is a very low-power service. There shouldn't be much magic required, simply a threshold for accelerometer activation similar to drop detection. This sort of protection can false-positive fairly safely - it is minimal extra burden to unlock your device if you accidentally drop it, for example.

Your description almost exactly matches the Maverick solar array produced by the Aussie company 5b (https://5b.co/) - you are definitely on to something.

Factory assembly and field deployment is a far faster, safer, and higher quality method of building solar farms.

Electric motors do get warm during operation, it is no surprise that some form of cooling fluid is desirable as the weight/power horizons are explored across the EV fleet.

This article doesn't touch on battery pack cooling, which is also a thing and much like motor cooling in that manufacturers want one coolant for the life of the product.

There's an important difference between prediction and detection. If you're in a nontrivial earthquake, detection isn't helpful: You already know it's happening.

The challenge is prediction.

There are a couple of startups that appear to be operating in this area with similar(ish) concepts to those described in the link.

precursor-spc.com - space based monitoring of atmospheric conditions, providing space weather forecasts and, apparently, earthquake prediction. Ionoterra - ground based monitoring of the ionosphere

I'm skeptical. If these companies were truly on to something then they would be selling their services to all the governments and would be household names.

So many people missing the point of 1:1s. They help to build a trust relationship between two people so that when there is something difficult to discuss, that conversation can happen. It is perfectly ok for most 1:1s to be fairly empty, if only so that once a quarter/year/whenever, you can have the promotion discussion/hopes-and-dreams chat/you're not meeting expectations wake-up call.

This isn't an "American" thing, that's a very inaccurate generalisation. Maybe more correct to say that 1:1s are useful in cultures where trust needs to be built before saying difficult things. Sure, people from some cultures can just bluntly say difficult things. That's fine. Many people cannot.

Best comment award! The point of doing these toy simulations, easily done on classical computers, is to understand the quantum circuits that calculate molecular behavior so that when those circuits are generated for nontrivial molecules the results can be received with confidence.

I believe the article makes a fundamental mistake with its inferred description of democracy. In a healthy democratic system there is not just one single central authority to which all democracy has to be driven. A healthy democracy has many layers and overlapping institutions, most/all of which are democratic in nature.

Thus, decisions to make things "more democratic" don't necessarily lead to giving more and more authority to "the government".

Outstanding comment! Bound to fly over the head of some in HN.
