While this works OK-ish for static images, it is almost unusable for animations. But for static images, blur+sharpen in Photoshop has worked OK-ish, too, for many years.

So the practical benefit of this is negligible.

What we need is a denoising technique where the denoising artifacts move convincingly with the features of the scene, so that you can use it for movies and games.

Oh and for games, as long as this is NVIDIA-exclusive, developers have to treat it as an optional add-on. For multiplayer games, that implies that Ray Tracing may never show details (such as a reflection of an enemy) that would give a strategical advantage.

Plus the real issue with contemporary game development is that consoles make a majority of the revenue (due to less piracy) but they choke when you have 50k+ polygons on an animated character. And you'll be limited to 2 GB GPU RAM on 30% of your PC player base, because they use laptop GPUs.

In the end, then, you usually don't have enough detail to make ray-tracing look good. It looks amazing for high-poly curved surfaces, such as those used for offline-rendered cinema movies. But on a blocky realtime game model, ray-tracing may also highlight artifacts.

Here's a ray-traced low poly bunny:
https://i.imgur.com/MGotRC7.png

Notice how clearly you can see that it is low poly. In a rasterization engine, one would "fix" this by blurring the edges with shaders and bending the corners with normal maps.

So in a sense, ray-tracing is too honest to work well with current video game models.
What if a vaccine is developed, wouldn't that make flying more palatable again?
End-to-end modelling is very enticing for the lazy engineer, unfortunately parameter control (knobs) are an important feature of most audio effects, and sampling enough of the parameter space will become prohibitive for more complex effects. That's why the traditional approach is divide-and-conquer.

Also, I don't think this approach won't work well with time-varying effects such as chorus, although I'm happy to be proven wrong.

I'm pretty sure blind people don't even notice this 'terrible UX' problem you describe, and that sighted folks aren't quite as jarred by it as you think.

This 'taste' issue probably matters more in some organizations than others. Hopefully they don't involve blind people in their business, because SPAs are notorious for being unusable to them. You can design an SPA with accessibility in mind (https://www.deque.com/blog/accessibility-tips-in-single-page...) but most devs either can't be bothered or aren't even aware of the issue.
You're right. We gotta push for Global Universal Basic Income. Someone surely has "X% of people live on less than 5 dollars a day" stats available on hand. If it makes their lives better over there, they have less incentive to uproot their life to go over here.
> telling someone you just should have done it differently boils down to dismissing the very real impact their race/gender/sexual orientation/whatever has on their life.

Race and gender may still play a role, but acting like it is the determining factor in one's life is too much. People have agency over their lives, and can make choices to make their situations better. The fact that someone is white or male does not negate this. I live in rural Missouri, and there are plenty of white people who make bad decisions and hurt their prospects in the process.

Also, "whitesplaining" and "mansplaining" are really incredibly racist and sexist. You should really consider using other terms.

I've been trying to learn enough about this problem to be of use in implementing this (playing around with my own language implementations). It seems like a real challenge might be around ensuring that your programs have extraneous 'type stuff' removed in the compiled program. Part of this could be helped with a nice way of doing proof irrelevance (eg. something like Quantitative Type Theory) and another could be multistage programming (eg. something like MetaML or MetaOCaml). The latter would make it much easier to do a more general form of Rust's monomorphisation of type parameters. You'd then may also want some sort of uniqueness typing and borrowing, but I have no idea where to get started on that! And you also don't want to drown in a mountain of annotations!

Buzzocks. UK over 18 population is ~52m. Give them each £1,000 a month, and you get a cost of £624,000,000,000, which is 3 times what the UK currently spends on "welfare"[0], and is about 3/4 of the overall UK budget. And you're cutting the payments of a sizeable number of current welfare receipients.

Sure you can find more recent figures, or play around with how much you claim you're going to give, but let's not entertain the fantasy that this is a "mild comparative cost".

So this seems similar to an IR (impulse response) where you get a snapshot of an amp mic'd up in a room with knobs fixed at a particular position. In the end, you don't get knobs to fiddle with.

Awesome, I'd love to hear Josh from JHS Pedal's opinion on this.
I’ve heard this referred to as Learn, Earn, and then Return.
It's not like the underlying problems and learning curves didn't exist before this, though. You had to learn to use and configure Ansible/Terraform/Puppet/whatever to get your "classic" servers up and running. You have to deal with secrets and configuration management somehow. You have to manually deal with your dependencies and inter-dependencies, and any possible conflicts that came along with that. Logging, service discovery, metrics collection, etc.

And for some folks it's better to continue using that "classic server" strategy and deal with those problems. Maybe they've already invested the time to learn to deal with those problems, or they already have systems and practices in place to deal with that stuff in an elegant way.

But a lot of folks are seeing the enormous benefits of containers and the ecosystems that come with them. For them it's worth the trade-offs and the time to take to learn how this stuff works.

Anyway, it's pretty clear at this point that this stuff isn't going away any time soon, and in fact only becoming more and more popular and useful. Clearly there's a reason for that.

I believe he shows in that book it's not a very good approximation - the market oscillates from overshooting to undershooting actual returns, and I don't think he believes market movements are always based on rational decisions, hence the title of the book.
I am also bilingual. My pet theory is that it has to do with growing up, family authority over you as a child, etc. As a kid if you say a strong curse word you could likely get in trouble and it would be a memorable negative experience. But if you say it in a different language outside your family home there is rarely a negative consequence.

My family was particularly absurd: my mother wouldn’t curse and wouldn’t say the word for shit in Russian but would use the English word “shit” as a curse word. Go figure.

If you're passingly familiar with Haskell or similar languages, you could give Idris a try.

Me not so much, while playing around with Idris and the respective book exercises was interesting, we aren't going to be doing GUI RAD tooling with such languages for the foreseeable future.
Damn, this area of programming sounds very interesting, but I'm so so lost in these type compositions... Is it this Idris video you are talking about? https://youtu.be/X36ye-1x_HQ?t=1716

Sorry, I'm not trying to be dismissive, I just want the ergonomics of expressing my intentions to the computer be free of all this boilerplate while leaving compiler a possibility to give me some useful feedback when something might be wrong, are we really not there yet or are there languages aiming to make dependent types practical? You mentioned Coq, but I'm still not being able to find any code examples or some getting started guide in its official documentation...

Excellent writeup, I love seeing real engineering applied to guitar pedals rather than black magic tone chasing.

I'd be really curious to see if the model could be expressed as a transfer function and compared to the schematic for the pedal. The Tubescreamer is a fairly simple circuit but the mystery surrounding it indicates that there are some weird variables at play with the component properties that would lead to additional factors in the transfer function. Wonder if those variables could be identified somehow.
This is an urban myth I'm afraid. This was not Bill Gates' pet project nor was it conceived by anyone at Microsoft. Like many other MS technologies, it was initially conceived by a small company that was first supported, and later bought out, by Microsoft. It's been around since the 80s.

How can you tone that down?
I feel like there's a huge amount of delayed demand. A lot of people I know are pretty desperate to travel as soon as it's safe to do so (without quarantine after each leg).

I don't think demand will take such a huge hit. It just depends on whether the airline industry can ramp up supply again quickly or if it will take a long time.

But I could just be in a bubble of people who still have jobs and I suppose that might all change as the true economic effects settle in

I agree with this - fares should increase by 3x at a minimum, more room given to passengers, and way way way more focus on customer service.

While what’s going on is terrible, personally I’m much happier that I don’t need to get on a flight every couple weeks. We’re finally realizing that being in the same room for certain meetings offers little value when compared to the cost of personal and environmental health incurred by a flight.

Remember 3 months ago when everyone was worried about global warming? We really need to take this as a forced opportunity to actually do something about it. We should not return to “normal” because normal was disastrous for the environment.

Another interesting thing about gaming is that it taught me at a very early age that reward requires effort. Even if the process as a whole, and we as humans, are still insignificant.

Using web technologies is not the same as doing crud web apps. Games for example are a very different kind of programming. And even if network admin and factory automation apps have web front-ends, that's still a minuscule part of the code.

A mile and a half of road/rail takes you a mile and a half. A mile and a half of runway takes you anywhere, including over oceans.

I don’t see rail as a particularly viable replacement for air in the US. Intercity Europe for 200-300 miles? Sure; it’s great. 2000 miles across the US? No thanks.
It's probably less dangerous (planes have HEPA ventilation systems, most metro systems don't).

But plane travel carries infected people long distances. There's going to be a bunch of countries insisting on 2 weeks quarantine for any new arrivals.

Funny that you mention HairWorks, because that one causes a lot of issues in practice because the hair is rendered in post-processing. Therefore, it is not present in the z-buffer so that alpha-blended transparent effects (e.g. smoke) may accidentally overlap with the hair. For an example of this issue, see the excellent Shadow of the Tomb Raider game.

Technically, if we could isolate/protect the old/risky people, this would be great for herd immunity. The "if i get corona" guy would probably just have flu-like symptoms, and contribute further to herd immunity by infecting other people, same age as him at same parties as he's going.

Much like commercial office space, companies have just paid all of the fixed costs for remote work, their employees have adapted their home offices.

Before, you were paying a global consulting firm to fly to your office to have an occasional meeting with your employees up to 3 days a week; now you get 5 days a week, no flight or hotel expenses, and 60+% of your employees are happier and more productive.
I think this is overly pessimistic. I used to fly regularly and I have every intention of getting on a plane soon. I’m booking extra trips so make up for the travel I’ve not been able to do for the last few months and to make up for missing things in the past.
Herd immunity is an illusion.

It would require that around 70% of people had been infected already. Using the USA as example: 70% of 328 million would be 230 million people. At a rate of 20000 new infections a day, as it currently is, it would take approximately 11000 days to reach that. That's 32 years. Let us assume ten times this rate was possible and this would still mean over three years. We do not even know yet if people will stay immune for an extended period of time at all after having gone through the illness.

All this still ignores that even in a country like Germany that dealt pretty well with the situation so far, the death rate is at approximately 4%. 4% of 230 million people means 9.2 million would die.

This also ignored any lasting damages to lungs, heart, nervous system and kidneys as they have been reported.

There will be no herd immunity as long as the disease progresses as it currently does.
I understand this is asked every time, but honestly in the 2 months of Covid19 and 20 years of post-9/11, I still haven't seen an answer that makes sense:

Why are we obsessing over airplane security so much, but completely ignoring ground transportation?

Never mind Metro/Subway/Underground, which we can claim not every city has (I'd still imagine total number of subway passengers daily outweighs airplane passengers or is at least comparable) - what about buses? Trains? Street cars and trams?

Any airplane I've ever flown had better filtering and circulation, more spacing and better hygiene, than any bus I've ever ridden in. Every airport terminal was more spacious than every indoors bus or train terminal. Across countries and continents this ratio has held true.

So why this obsession with airplanes as the vulnerable part of the equation? Is it all just... human inability to calculate risks and our focus on the "flashy"?

I've done 50-75 flights a year over last 10 years; none last 2 months obviously, and I don't foresee any soon; but I'm DEFINITELY not going to take our friendly neighbourhood Toronto subway if I can help it, as much as it's the key to fighting traffic and pollution.

This should be throwing our entire transportation industry into disarray and restart fundamental discussions about urban planning and urban landscaping of the future... and yet I only ever see the airline industry mentioned.
