The cost of returning containers whole, washing, inspecting, rejecting breakages outweighs the benefits.

It would be much more efficient to use extremely lightweight containers that can be crushed in a reverse vending machine in any supermarket.

That's how returnable bottles and cans work here in Norway (and several other European and Scandinavian countries). At the moment it only covers drinks containers but that is probably because they are the only ones that pose a major littering problem.

See https://www.tomra.com/en/collection/reverse-vending

This way the energy cost of returning the containers is minimised and the returned material is suitable for immediate, industrial scale, automated recycling.

But of course that doesn't allow the producer to use just any container so it limits their branding opportunities.

Lol, what consumer protections?

DCT is basically a type of DFT (for functions with symmetries in the values). You can easily implement a fast DCT using the FFT at the expense of a constant performance penalty (because the more general code can’t skip doing the redundant work implied by the symmetries in the data). The techniques used to implement a fast DCT are pretty well the same ones used for an FFT.

The basic concept of the DCT as used in compression applications is that the FFT only works for periodic data, but the arbitrary data in a block of pixels are not periodic, so we pretend that it is part of a periodic function with double the period where we mirror the data back-to-front on the other half. If we didn’t have a DCT implementation per se we could explicitly mirror the data into a larger array and then run an FFT, and then just look at half of the coefficients (the others are zero).

This still creates some artifacts since the interval of our data is not actually periodic, and derivatives aren’t necessarily matching between the two ends. But it turns out to be more-or-less good enough.

An alternative approach to approximating a function sampled on a uniform grid over a non-periodic interval using the FFT is to first estimate the first few derivatives at the endpoints and then subtract off a polynomial matching that data. Then we can more safely pretend that the remainder is periodic. cf. http://zindajaved.com/data/publications/javedTrefethen2014b....

> Someone correct me if I'm wrong, but Raymond Scott never wrote music _for_ cartoons.

You're not wrong. See:

https://www.raymondscott.net/features/accidental-music-for-a...

I find his music to be clever, entertaining and well ahead of its time in many respects. His music was sometimes dismissed by jazz purists of the time as being "novelty" or "dada" jazz.

There was a documentary I saw a little while back which included a discussion of Scott's surprise when he started receiving royalty checks again the 1990's when Ren & Stimpy started to use a lot of his music as well.

A complete 100% decoupling may be impossible but the US is not so reliant on China that a 90% decoupling could be considered suicide. It would take effort and would result in many lost dollars but the US could move its manufacturing out of China.
I don't see how this is relevant. Certainly related, but not immediately relevant. The Nyquist rate / frequency (depending on where you stand) determines whether the process of sampling is invertible, but the FFT exists independent of the process of sampling and is always invertible (in the maths). 'acchow's question is whether this holds in practical systems, like computing the FFT and IFFT with the finite precision + finite range numbers that we can use.
Interesting you've mentioned this. I'm working on a series of YouTube videos that is aimed to teach engineers a) how to think and design an application from scratch and b) How this process works at companies so they get a sense of what it's like professionally.

The channel is called "Think Code" and I'm working on different videos focused on a) teaching people how to code quickly and easily (free of course), b) give junior engineers and understanding of what's expected from them professionally and c) share advice to engineers on how to become better engineers. e.g., problem solving, how to learn new systems quickly, trouble shooting tips, practical advice on scrum that actually works, etc.

Let me know if you would be interested. I'm working on releasing videos next week.
> I don't understand how there could be that many jobs eliminated by a merger while the beer output remains the same.

This is what a merger is for. You use it to enhance "synergy" (I hate that I have a legitimate for this now) and in so doing can fire as many people as possible to maintain production.

> It also often takes years for mergers to completely eliminate redundant employees.

It is possible to prepare for a merger by pre-emptively selecting/preparing a dossier (if that is necessary, this is the US so probably not) so you can fire them as soon as all the paperwork clears.

The Engineering of Droplets and Their Formation in a Commercial Inkjet Printer
Is there any information out there about what the terrestrial requirements to actually use this service are going to be? Is it going to require antennas similar to line-of-sight microwave internet providers like Monkeybrains? How much is that hardware expected to cost?

The satellites themselves, the way they're being deployed, what altitude they'll be in orbit...all of that is really fascinating, but I'm very curious what this is actually going to look like to use.
If anyone wanted to send a file they could write it to a CD, DVD, or USB stick and post it. They can leave it at a dead letter drop, under a bench in the park.

One can even print it on paper as bar codes or similar and send it in the post so that simple external inspection would not reveal that it was not just an ordinary letter.
Still costs several thousand dollars.
Cool! I noticed that it uses a star map to locate itself, like the SR-71 blackbird did before the time of GPS. Is this novel or common for satellites?
Rearanged your js sample a bit, now it runs in ~26ms (first time) and ~11ms (subsequent times) instead of ~220ms in the chrome developer console.

{
let a = Math.pow(2, 1023)
let t = performance.now();
let max = 1e7;
for (let i = 0; i < max; i++) {
a += i;
}
console.log(performance.now() - t);
}

Main problem was, that you should declare a with let.

That benchmark is a bit strange/flawed anyway. You're initializing a as pow(2, 1023), then adding numbers in the loop. But since a is already such a large double value, the result won't change. The numbers you add are too small to make a dent in the value of a, likely because a isn't an integer. It's a double with a limited precision for large integer values.
So by the end of the year (best case) they will start commercial service after 6 launches. And plan on 2-6 more this year.

It’s a “user terminal” about the size of a pizza that can be mounted in a roof. Since it’s a phased array the direction doesn’t matter (unlike a traditional dish for a geostationary satellite). Once they are producing them in volume they should be pretty cheap.
I don't think they've announced much regarding the pricing or specifics of the terminals, but Musk has said in an interview they will require an antenna array with line of sight, and will be about the size of a pizza box.

> This is a big fallacy with academic research: nobody needs to be honest or truthful, and as much as you like to believe they are, they have no reason to be honest.

They don't have to be as long as others can verify their findings. At some point, mistakes and dishonesty should be treated the same way.

> Usually a goal is the prerequisite of the funding. If that goal doesn't align up with the interest of the company/or the funder, there won't be any funding to begin with.

I think we're very much in agreement. I just don't put that as academia's problem, but rather explicitly on how we fund it. A.k.a blame the game not the player.
opinions vary but even my most angry brexit voting friends of mine would not do that in a re-vote

EU election polling may suggest otherwise. There's something slightly weird in UK politics where the media predominantly takes one side of a debate and then it seems to become socially unacceptable to be on the other side.

The brand new Brexit Party look to be getting double the vote of any other party, yet other than of parents and in laws no one I know has offered up that they were on the leave side. Yet I could name maybe 100 people who have talked about being on the remain side.

I've been brought up not to talk openly about politics anyway, but it seems a shame to me that there's a relatively silent majority.

Anyway, fully agree with your post otherwise. It looks worse than Eurovision!
Hi. I would like to take the opportunity to get your opinion on quantum computing.

My understanding is that there is a significant work in theoretical quantum computing done by you and many people. Results presented by you seems impressive. Congratulations.

On the other hand - everything I read, hear and try to interpret about D-wave seems like a nonsense. They show approximation computations and compare it to classical algorithms that provide exact results. But classical approximation algorithms work much better than their quantum computers. I do not see how scaling this approach could lead to anything that you describe in your paper.

In this regard - is my understanding of D-wave correct or does it provide some value that is better than classical computers?

Can d-wave or IBM's creation be used to do computations described in your paper?

Is their approach worth anything?

[edit] Of course I'm not asking about now - my question is whether there is anything connected to exact results (like factoring) and exponential speed-up in d-wave approach.
I'm confused as to why the takedown is worldwide. Does China threaten the company if they don't apply Chinese IP law apply outside of the country? Since their IP laws are terribly primitive they clash with the rest of the world, so that seems impossible.
Very interesting read though talking about “Islam” as a religion or culture is quite misleading because of its diversity and pluralism. Indeed very different from any western Christian culture.

There are 8 official jurisprudence (schools of law, fiqh): 4 Sunni, 3 Shia and ibadi (Oman only). Only about 15% of sharia law is in consensus. So it’s misleading to generalize what Islam stand for (when referring to it as a culture based in religious law) or not on any particular issue.

Ie some of these schools of law, majority, would be more respecting of women rights (ie abortion) than few states in the USA. In fact I’d say legislation like in Alabama is a grotesque caricature of what some Americans believe is sharia law.

Also the comparison to a PNG instead of a JPEG was a bit disingenuous since PNG is a lossless codec. I understand it was done to sound impressive but if you compare lossless PNG to a codec that just reuses the same frame and uses a lossy codec on top, it's not surprising the video will be smaller.
I've noticed my video player does this, but only when using the "5 seconds forward/back" arrow key commands. Tap the left arrow and you end up skipping back to the same moment over and over, even if you wait a bit.

Interestingly, YouTube doesn't display this behavior. I find it kind of annoying, to be honest. Sometimes there are reasons I want to go exactly the same duration back/forward, every time.

If they can prove that they were first to market with the game and trademark AND that the other company cloned the game and registed the trademark in bad faith then the trademark should be revoked from the new company and assigned to them.

This would be the logical solution.

(I am sure some people will harp on about "You cannot prove bad faith" but this is what a court of law should be able to determine. You don't create a copy of another game and use their trademark in any other way apart from coincidence which is highly unlikely in this case)
Imagine a file split into 100 blocks.

You're the seeder. Initially you're the only one with all 100. And everybody's gonna download things sequentially.

Imagine 300 peers grab block 1 from you. Gonna be pretty slow, each peer gets 1/300th of your bandwidth.

Imagine those 300 peers finish block 1 and move onto block 2. Same bandwidth crunch. Although new peers can at least get block 1 from that initial cohort of 300 peers. But nobody can blocks 2 through 100 from anybody but you. Not ideal.

Now repeat the process for 3 through 100. You're gonna be the bottleneck for a loooooooong time for those remaining pieces.

...

...

...now imagine we do it differently. Those 300 peers each grab a random block. This part's just as slow.

But once they have their initial randomly-chosen blocks, our bandwidth explodes. Each of those 100 blocks is now available from ~4 sources (you, and roughly 3 others). And you could even log off at this point, since there is a complete (distributed) copy of your file out there.

As more blocks are exchanged, the effective aggregate bandwidth rapidly increases even farther.

If you assume a Moore's Law-like increase in physical qubit capacity each year, it will take slightly under 20 years. That also assumes the rate of decoherence decreases commensurately.

The reason you get pushback is because Moore's Law exists within a historical context in which it was actually plausible for exponential increases to occur each year, year after year. The field of quantum computing is so nascent that such a context is utterly alien to it. We simply don't have the economies of scale, engineering capabilities nor even theoretical groundwork required to achieve and sustain those kinds of improvements. The other reason is because transistors and qubits are not directly comparable, and you shouldn't try to infer the growth trajectory of one from the other's.

So to answer your question directly - it's not nonsensical at all to measure and forecast the rate of physical qubit capacity increase. The report I cited in another comment does exactly that, which is how you can derive that 20 year estimate I made. But we don't have any evidence those kinds of annual doublings will be achievable anytime soon, so most of it comes down to educated guessing.

According to the linked site:

> At end of life, the satellites will utilize their on-board propulsion system to deorbit over the course of a few months.

How to Create Local HTTP Yum/DNF Repository on RHEL 8
Agree with you on mixed feelings, this is complex in many aspects.

Compared to buying packs of Magic or Pokemon cards, where a couple cards in some sets are exponentially more desirable than any other card (and valued as such on the secondary market), loot boxes in many games aren't that different. Except there is physical/real friction/limits to buying a pack of cards as a kid- e.g. getting to the store, going to the store with a limited amount of cash, etc. Compared to a f2p game where, if access to IAP isn't restricted, there's essentially a limitless amount that can be spent on a credit card without the kid realizing the impact of doing so.

The gamer inside me hopes this could help get rid of a lot of the cookie cutter f2p games and possibly encourage more higher quality games to be developed that are bought upfront like old times.
