> Plus, LEDs don't have anything like a blackbody spectrum like a heated filaments

What is the physiological mechanism you suspect makes this matter?

I don't see any real way an LED which is metameric with sunlight would be able to make a difference (except possibly for people with some form of color blindness - who could possibly have different metamer "groups")

> 0. The creation of a deep, long-lasting relationship between tutor and tutee

I have spent over a decade in school and this has literally never happened to me. I went to second rate middle/high schools, so maybe teachers in "good" schools have some deep insight which makes interactions with them actually desirable?

In any way, this desperately does not scale, at the current ratios you would require a single teacher having "deep, long-lasting" relationships with ~hundred students at once, which just isn't feasible.

Even if every adult in the society got involved, the proportion drops by just about an order of magnitude. I can't imagine myself tutoring a single child, let alone ten of them!

> explain in layman's terms and THEN explain the formal properties?

The explanations are definitely very lacking of formalisms. There even isn't any proper explanation of what a vector space actually is.

It doesn't seem to pretend to be a full textbook replacement, more like a supplementary material, so I don't think it matters all that much.

> Poor people, they should rebel.

Rebelling against the school system is inverse tragedy of the commons - large individual loss and small societal gain. There is no real incentive to do that.

If you don't understand logarithmic scales, maybe you shouldn't be specing parts for a network-connected gizmos?

Oooh, that's pretty awesome then. I was pretty sceptical after reading about somewhat "meh" results for deep learning applications a few weeks ago.

There are commercially available FPGA JPEG transcoders?

High end FPGAs cost an arm and a leg, so I find it hard to believe they would be cost effective, though Intel seems to claim otherwise.

> Do missile systems also lose track of their position midway through a flight like our phones?

Civilian grade GPS receivers are intentionally crippled to stop working above some altitude/speed limits.

EDIT: It seems that the COCOM limits apply only after "1,900 km/h at an altitude higher than 18,000 m".

However, looking at the ublox receivers as an example, they have to be explicitly configured to operate at aircraft-level speeds, which smartphones likely aren't.

You seem to be doing drugs wrong - I have taken drugs recreationally and have never been to a "party". Actually thinking about it, I have never taken drugs in any social setting at all (including alcohol).

Why would you chose to work on a weapon system if you are unable to handle the fact that weapons are used to kill people? It's literally the job description.

That is the difference between them and Tesla engineers - people killing is a bug in self-driving cars, not a feature.

> Assembling this kit would be much easier (and fun) then starting from scratch.

What is so fun on assembling a kit? The populate-the-PCB is probably the most mind-numbing part of the whole hardware engineering business. Design and debugging is where it's at

> weather changes would probably have a far greater effect on cable length than the imperceptible drift of the endpoints (which suggests another crazy idea interesting in its own right)

There is a clock running for over a century based on a similar idea: https://en.wikipedia.org/wiki/Beverly_Clock

You would think that right? Except then you actually want to run a simple python script on Windows and observe things like: os.rename not being able to replace opened files, the default encoding not being UTF-8 (wtf), not being able to just `pip install scipy` because of some weird BLAS/MKL dependency...

The food safety concern about porosity and bacteria growth would probably apply for stuff like this.

Should be easy to solve by reprinting the prosthesis every few months or something like that.

> This KU115 chip has a project price of ~$2000.

That seems odd - just the XCKU115-2FLVB2104E FPGA goes for $9000 on DigiKey.

> This is a big part of why I bristle when Uber fans claim that ride sharing makes public transit obsolete.

Is public transit where you live like, insanely expensive? Quick back-of-the-envelope calculation reveals that public transit is around 1-2 orders of magnitude cheaper than Uber for me.

The survey might have been setup so that there is a constant amount of respondents? After some point, you don't really need more.

However, judging by StackOverflow Trends [0], it's even dropping.

Applying fourier transform to impulse response results in the frequency response:

I think this would work only if the system in question is reasonably linear though, which wine glass might not be (?)

I have limited experience, but I think that usually you would take this into account when building your loss function and heavily penalize false negatives during training.

It's also what makes the vulnerabilities not-that-bad. It's just another "peripheral not properly handling firmware updates" thing, which are all over the place.

I mean, it's cool from a security research perspective, the PSP isn't just some random keyboard/HDD, but the severity seems overstated.

It's not about using the system as an "user". It's about the fact that it bases democracy on principles which are way beyond the mathematical capabilities of 99%+ of the electorate!

I mean, if my government decides to use some crypto/blockhain magic, there is no way I can figure out if using hash algorithm H in a method X is valid choice or if it is a backdoor/negligence.

This is an issue which simply does not happen with paper ballots (backdooring these is of course possible, but really expensive especially at scale). The attack surface is easy to reason out, unlike with cryptography.

Maybe it does not matter though (and maybe I am afraid of mathematicians secretly taking over the world, ha!)

Migrating elections to a technology one needs mathematics/CS PhD to understand just a part of from technology that can be understood by a middle schooler doesn't seem all that great.

The article talks about "fully-transparent voting solution for this future", yet I somehow don't see any transparency when it all relies on magic only a negligible part of the population understands.

> And since it's a public blockchain, you know exactly which token went to whom.

You don't (well, shouldn't) know with Z-Cash/Zerocoin

> You wouldn't drink gin and asprin.

You would do exactly that though, salicylic acid is found all over the plant world.

Three of these were scheduled to be replaced several years ago at my university - the administration however pulled the "voluntarily call the historical conservationists" trick and they are still operational.

The (admittedly just two) places I have seen had a "normal" elevator for this purpose.

Having JavaScript enabled when buying drugs over the internet isn't exactly the smartest idea anyway.

Why would you need a "real" phone for UI testing? Android has a very good emulator available.

The math necessary for ML/AI (statistics/vector calculus) is mostly taught at undergrad level though isn't it? So most engineers should already have it covered.

On the other hand, they paid the opportunity cost of not spending their time learning something that could be actually used to improve their living situation (electrical/mechanical engineering comes to mind).
