Power lines are cheaper and more efficient than pipelines, and they always will be. Ammonia will be a storage medium.
It's not just that ray tracing looks better than rasterization for the same scenario, but that some scenarios are simply impossible / impractically complicated to render with only rasterized graphics. Just one example is specular reflections with non-screen space content and a dynamic environment.

Rasterized graphics can do specular reflections quite well as long as the reflection only shows things that are currently in view. One can then perform a limited form of ray tracing in the depth buffer to detect which part of the screen is visible where in the reflection. However, as soon as we want to reflect things outside of the screen it gets tricky, as we can't simply perform this screen space ray tracing. Instead, we have to rely on pre-baked reflection map textures. This works well enough for static objects, like the environment, but you can't see dynamic content, like players, as they can't be pre-baked into the texture. Also, it's useless when there are no static objects, like in Minecraft where there's no such thing as a static environment -- every block can change dynamically. And this is where the limit of specular reflections of rasterization is basically hit. There are of course workarounds, like rendering the scene a second time from the mirrors perspective, and then combining the view render and the mirror render, but you can imagine it gets prohibitively expensive quite fast as you add a few more reflective objects to the scene. Also, this method doesn't work for glossy reflections -- that's even more complex.

So this is just one example of how rasterized graphics limits us -- we can't have more than a few reflective objects in a scene which features dynamic geometry, which is a very sensible thing to want to have!

In my opinion, ray tracing really is that much better than the approximations we've developed. Also consider how much faster / cheaper it would be for a studio to create new graphics engines when you only have to write 1000 lines of ray tracing code instead of 100'000 lines of rasterization hacks (for a worse-looking result!).

That is not how this works. The value of the Euro is depressed compared to what it would be if the deficit running regions were not part of the common currency.
I was thinking about this idea, if we print money and distribute it "wisely" among the lower income classes, this would debase the currency proportional to the amount printed, harming primarily those who are wealthy, proportional to their wealth, and the money will eventually flow upwards through the financial system, primarily through consumer spending, but ultimately back into the pockets of the wealthy.

Of course, inflation in certain categories would need to be taken into consideration, and other factors, but is this idea a non-starter for some reasons I'm overlooking? Excluding politics of course, for the purposes of this mental experiment.

There was also an article posted here in the last two weeks or so about a massive global short situation with the USD, I have it in my mind that the particulars of that situation were conveniently complementary to this idea, although I may have that aspect completely backwards.
I realize the point of this is to be simple, but I can't see myself using it unless there is some way to delete elements after they have been created (maybe dragging a diagonal line with right click should delete anything in the box defined).

I know you can use Ctrl-Z but if I want to change a box I made early on then this doesn't work because I'd have to basically start over from scratch.
> Why are we still building towns with the pipes under roads? Keep them under the sidewalks with loops in the cement blocks so they can be easily lifted up and moved for repairs.

This isn't a bad idea for maybe a single utility but I dont think you are considering how many utilities are under the ground: water, sewer, street runoff, natural gas, electricity, telecommunications. Each of these may have multiple lines for each of service, distribution, and transmission. One of the reasons streets get torn up a lot is that there is a low of equipment underground!
People in any category "almost never achieve outlier levels of success"; that's what "outlier" means. If you mean that people with children achieve outlier levels of success much less often than people without children, then I think you owe us some of the evidence implied by that word "empirically".

J S Bach had 21 children. Karl Friedrich Gauss had 6 children. Warren Buffett has 3 children. Rembrandt van Rijn had 5 children. Isambard Kingdom Brunel had 3 children. Charles Dickens had 10 children. Charles Darwin had 10 children.

The only one of those I picked on the basis of knowing about their children was Bach; the others were the first super-eminent people in their fields who occurred to me that I didn't know were childless.
This mechanism also included an HMAC, responsible for authenticating the bitstream. That's useful even if the bitstream is public knowledge.
I love Python too! The style of Scala used in this book is much closer to Python than Mathematica or Scheme, with many of the libraries involved being carbon copies (os-lib, requests-scala, ujson) so you will feel right at home.

As to what you get going to Scala, it depends what matters to you.

Does 50x faster compute matter to you, for the code that’s CPU bottlenecked but inconvenient to rewrite in C?

How about easy parallelism, to trivially and fully utilize multiple cores without clunky subprocess management?

How about easy packaging? One builtin command to package your program as a single file that can run anywhere with a JVM, no other global installs required?

You do give up some things using Scala: compile times are slower than iterating on Python scripts, the JVM runtime takes a second or two to warm up when launched, and you don’t have quite the same numpy/scipy machine-learning ecosystem. Whether that is worth it is up to you!
So, for example, a power line from Algeria to Europe is cheaper than a ship-based ammonia scheme? Or northern Australia to China or Japan?

Power lines are a winner for short distances. Pipelines some longer distances. And ships for the longest distances.

I don't disagree that the media is causing a huge amount of problems but demand is actually up because most people are working/layed off at home and they're definitely using more supplies than they would if they were at work. And before you say companies are using less supplies, corporate supply chains and home supply chains are COMPLETELY different and often use different farmers/gatherers, etc.
Their core argument seems to be that we should place less value on those dying from Coronavirus, because most of them "would soon have died anyway" - and more value on the percieved economic risk of the lockdowns, because this somehow represents "the people we can see dying in front of us".

Hence easing the lockdown, focusing on the economy and just letting the virus take its course whould naturally be the more "humane" solution...

Thanks for this. DSPs that accurately simulate hardware are not as trivial as one might initially think. I've done some thinking on this front, and the DSP based approaches that simulate hardware are likely making many shortcuts. Take a zener limiter circuit for example. You could just rail samples with an amplitude comparison, but that's a bad sound. So what I think most limiter DSPs do is apply a shaping filter to that. It's an approximation, but not really capturing the characterization of the circuit. The simplest way to get an accurate response is with SPICE simulation. I'd love to see a DSP that specialized in realtime SPICE simulation. Failing that, you have to sit down and do the math for each circuit yourself to establish the relationships between component values and signals, then code that into your DSP. It's not an unreasonably large amount of work, but judging from the people I think are selling audio software, I would be shocked if anyone is actually doing that.

The problem is just too ill-defined to fit directly with a logistic model or really any general-purpose model (such as gbm, etc). You need better priors, either in the form of good, specified dynamics, or in other terms.

You could do a regularized stratified model [0], for example, in the case where you have plenty of data in one country but not in others, or similar cases which incorporate dynamics (log-log models of growth are also pretty good). Overall, I think it's just too hard of a problem as it is very ill-posed—even if we knew the exact dynamics, any small perturbation in the data samples significantly changes the best fit (in other words, the dynamics of the system are 'chaotic').

> I DDG searched "do economists support anti price gouging laws". Here's the top results. Every one of them disagrees with you.

If you think that, you must not have even read the links you gave me. The first one takes a turn halfway through with "but, as with so much of economics, there is disagreement," and has an economist outline a lot of the problems with price gouging that the other economists are missing.

> Can you provide ANY literature suggesting mainstream economists, on average, support price fixing, confiscation, or purchase limits as a means to allocate resources effectively in a crisis?

Frankly, I don't really care if "mainstream economists, on average" support anti-price gouging legislation or not. Like I alluded to before, they have their biases. For instance, they spend their careers focused on certain problems and not others. That doesn't mean those other problems are unimportant and can be ignored. Good policy will ignore economists in some cases, when factors economists de-prioritize need to be prioritized.

Your qualification of "mainstream" is also kinda interesting. I don't consider economics to be any kind of settled science. It's almost certain that there are serious problems caused by following "mainstream economics" due to its flaws, omissions, and biases. Its ideas should be given due weight, but they're not the gospel truth. That's especially clear on the question of price gouging, because even in the survey you cited there were economists that strongly supported efforts to curb it.

>>> It doesn't matter where you go, everywhere you will see markets are better at allocating resources.

> The military primarily gets work done by allowing private contractors to bid on projects.

That's clearly not what I was talking about. If, as you say, "markets are better at allocating resources" everywhere, don't you think a front line army unit should get supplies allocated to it based on market principles (e.g. the unit bids against other units in a market to get more ammunition)?

It is extremely easy to let your C++ code get into long build times. People get fond of putting code into the header, for example. This adds that compile time to every file that includes that file. And it prevents you from using forward declaration, which then requires including those definitions in your header.

With discipline and tracking the build time, and tools that record how long each build step takes, you can keep people from doing things like declaring a Boost multimap in a header file. They can go ahead and use it but hide it in a cpp source file behind a pointer or a virtual interface.

I've noticed that some people fall in love with C++11 move constructors, and they are pretty cool, but unlike a reference or pointer they require full type definitions in order to pass "by value." So that's annoying.

C code is definitely faster to build, unless you've got some crazy programmer who reimplemented C++ templates using five level deep nested macros.

There are different kinds of S-curves.

Some of them are basically exponential at the beginning (the logistic curve). This makes perfect sense in modelling an infectious disease - initially, all contacts are susceptible. Thus you have exponential growth.

Others, for example the CDF of a normal (which is often confused with the logistic), is not exponential at the beginning, but decays much faster (the derivative is exp(-x^2)).

Arctan decays much slower (derivative is 1/(1+x^2)).

So, S-curves are sort of linear in the middle, but sort of exponential or exp(-x^2) or 1/(1+x^2) or hyperbolic at the ends, and which one of them it is tells us a lot about their behaviour.

Note also that without any social distancing or other measures and a sustained Rt of, say, 3, the inflection point will only occur once about a third of the population are infected, and thus it makes perfect sense to model it exponentially while still being below 5%, say.

The "hacks" to get semi-decent lighting are not free. Every time you want another lighting effect you need another hack. The hacks are getting more elaborate and complicated as people want a better looking result. It can be more difficult for artists to work with the current system since everything you see is an artificial hacky construction.

We're now approaching the point where raytracing is the simpler, easier, faster alternative. It's also great for artists because the results are more predictable. Raytracing gives a better result, or simply makes it possible for things like good shadows, transparency, reflection and global illumination.

It might take a while, but the current way of doing things is a dead end. If a triangle is smaller than a pixel, you're basically just raytracing anyway. That's also becoming a more common thing these days. There will continue to be hybrid solutions for a while, but as raytracing takes over certain portions of the rendering, which it is good enough for already, there is no reason to go back.
What you describe is not in conflict with the Apple/Google proposed solutions. Or rather, it (the part of reporting and aggregating on the server side) is not part of the proposed solution.

When tested positive, to which server the diagnosis keys are reported to can vary depending on the platform and app. It could be reported via a goverment approved app, or reported to Google/Apple provided server. As long as Google/Apple aggregate the diagnosis keys across multiple servers (or even multiple servers across multiple countries), we still take the full advantage of this contact tracing framework.
Fountain codes provide a reliable encoding stream for UDP. This prevents the need to use a complex transport on top of UDP for both unicast and multicast streams.
You are correct, the interwar period is generally not considered an arms race, especially in the early period there were serious and to some extent successful attempts at arms reduction. But one is not correct to conflate pacifism with appeasement, the former a movement borne out of a sincere hope that the disaster that was WWI would never repeat itself, the latter a British policy that hoped to direct the German expansionism towards the USSR only ("no more territorial demands in Europe").

Among liberal democracies there was an anticipation that Germany would annihilate the USSR, and that Germany could be handled after that, a complete miscalculation. They could have thwarted the military buildup in Germany through other means than war, for example through boycotts like the US currently is so fond of. Or by granting the League of Nations better and sharper tools, but they chose not to. So there was an arms race, but it was mainly between Germany and the USSR, until the west realized that it was too late for Germany to be controlled.

As a side note, your theory that "Disarmament doesn’t prevent war. It only prevents winning." and “'Transparent and neutral international agencies' are a pipe dream." aligns well with fascist ideology. Not that you necessarily harbor such leanings. It just aligns, and is definitely very far removed from the ideas that underpin for example the United Nations, which could give you some pause.

Sorry if I came across that way; that's not what I meant. Of course there are some regulations that are overburdening. But this is like saying we should repeal TANF because it has a non-zero (very low) fraud rate: it focuses on the wrong thing. The comparative burden between the rare overzealous regulation and ladder pulling regulation is bonkers.
