It's great to have well-synced audio in AV files, and even better to have a way to shift audio and video sync at playback time to cater for delays in the audio or video path - bluetooth earbuds seem to be very laggy for example. I am hugely grateful to the developers of VLC for providing this feature.
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.
"Burn it all and filter" is basically pyrolysis - use high temperatures to break chemical bonds and turn complex substances into much simpler substances which can then be reused.
Problem is the energy input required for those high temperatures. It costs money to consume that energy, quite often more money than you make by reselling the simpler substances that come out the end of your pyrolysis process.
Grinding the blades to use as filler is indeed one of the downcycling routes currently in use for old blades. It is energy intensive and there is limited demand for the filler because it has to compete with other very low cost materials, so the economics are not usually favourable.
That source would be from the bp statistical review of world energy, a widely quoted and surprisingly impartial collection of energy statistics. Charts and stats from that annual publication turn up all over the place. Disappointly, they're going to stop publishing it from next year.
You can confidently bet that James Patterson's team is already using GPT3. For better or worse, he has been the Henry Ford of novel production and modern technology like GPT3 is exactly the force multiplier the team would want to adopt.
OMG look at the Y axis scale of the graphs. Everyone else is 0-1000+ (often 0-2000), Magnus Carlsen's graph scale is 0-200.

I'm surprised spamgourmet.com has not been mentioned - created-on-use forwarding addresses with a built-in self destruct. It is a superb solution.
