A useful if comparatively unsophisticated application might be in urban spatial and transport network analysis/planning.

Typically, spatial models use a basic circular catchment geometry to approximate random travel patterns across a city or suburb or neighborhood. That invariably influences a network's or neighborhood's real-world shape when it gets built/modified.

For example, consider the area of influence ("walkshed") of a bus stop or train station, and how perhaps walkability improvements across surrounding streets might be prioritized as a result of modelled demand distribution. A grasshopper solution could apply if the bus/train trip is the first hop and the last-mile walk is the second hop and the street grid or neighborhood is the lawn.

A more refined initial catchment geometry based on these grasshopper solutions could ultimately make a difference in how scarce resources for urban/transport infrastructure get allocated, lifting net benefits on average. It should at least make for more realistic predictions as well as more accurate explanations of real-world observable travel/development patterns.

The paper mentions the "ant problem" as an extension of the grasshopper problem, i.e. excluding disconnected shapes. That would be even more useful for the application above.

Of course, as a first order approximation, a simple circle catchment geometry isn't necessarily terrible (being not that far from a cogwheel), but there's probably a category of analogous distances in urban life where non-circle-like shapes would make a marked difference.

"For example, we teach students in high school that if the product of two polynomials is zero, then to solve we set each one separately equal to zero. Yet this does not hold with nonzero numbers. For example, working in polynomials with real coefficients, we know that f(x) * g(x)=0 implies either f(x) = 0 or g(x) = 0. Yet it is not the case that if f(x) * g(x) = 4, then either f(x) = 2 or g(x) = 2."

Does this really require knowing abstract algebra? Seems obvious to anyone doing any sort of multiplication that if the output is 0 then one of variables/functions has to be 0, if it is nonzero then the variable/function can be anything but 0.

If you look at Portugal, who has had the most success in reducing drugs, they decriminalized drugs. Which meant they kept them illegal, but if caught it was equivalent of parking ticket fine, but also if person hit a threshold of too many fines, there was drug addiction therapy required. Decriminalization removes the excessive fines, time in jail, and removes the criminal record black mark.

Atlanta GA has decriminalized marijuana this year. If caught it's a $60 fee only. Previously it was $1000, up to 6 months in jail, and a criminal record.

This decriminalization should be applied to all drugs. This has been proven to work, everywhere it has been tried.

Yes you could argue that China is paying a higher cost now, but their goal is to protect and nurture their own industries so that those industries can dominate the world later on.

It's like South Korea in the 1960's and later from what I've read. The government invested and subsidised (i.e. protected) their young growing industries so that they could grow to be competitive on the global market.

The USA did likewise when it was young, with tariffs on imported goods, blatant copying of intellectual property, etc.

I am going to just forget all the countries that are still on GSM. Let's say we have 5G right now.

1) The theoretical speed is one thing, the real one is another one.

2) There is more than one node connected to the network

3) TCP needs some package interchange to increase the window size

4) Latency with the server where the page is hosted is not going to be 1ms, you are lucky if it is around 20ms.

5) Serves have more RAM because they use better CPUs, it means they are more expensive.

6) Who connects to websites nowadays? Mobile is the way to go now (It means slower CPUs, less RAM, less power consumption, etc)

7) Why are you going to transfer a complete netural network instead of sending the data to the server. The data is going to be smaller than the network and you avoid the risk of someone cloning the neural network for their web site.

8) There are no useful applications in web sites for neural networks. It is a non sense for me (please probe me wrong and show me an use case where it makes sense)
> 8080, please. The 8086 was designed to be assembly-level source compatible with 8080's so porting software (here's to you, Gary) from CP/M would be easy.

1. The 8086 was not designed to be assembly-level source compatible, but nevertheless intended that assembly code from 8080 could easily be ported to 8086 (mostly find & replace)

2. Zilog developed a different assembly language for the Z80 than Intel used for the 8080 (for copyright reasons, I think - though nearly everybody would agree that Zilog's assembly syntax is better; compare for yourself: http://nemesis.lonestar.org/computers/tandy/software/apps/m4... ). The Z80 assembly language was a strong inspiration for the x86 (8086) assembly language (Intel syntax).

3. The Z80 introduced two index registers (IX, IY) over the 8080. A strange coincidence that Intel also did introduce two index registers for the 8086 (si, di).

4. Do the INI/INIR/IND/INDR/OUTI/OUTIR/OUTD/OUTDR that were introduced by Zilog for the Z80 strongly remind you of the INS/REP INS/OUTS/REP OUTS (just consider that the 8086 uses the direction flag) instructions of the 8086?

etc.

TLDR: Intel took more "inspiration" from the Z80 than is generally acknowledged.
If there's one thing about management it's that success is fully theirs and failures are trickle down to everyone else.

I worked on a major and successful product launch that made a big company big bucks and watched as none of the promotions and bonuses trickled down past management despite the untold hours and sacrifices by the development team. When the company decided there were too many smart people, they created disincentives to staying around and subsequently all those bright people got the hint and found other jobs. It was more humane than a layoff, I suppose, but so so deceitful and cynical. And so it goes.
The executive summary doesn't make sense:

"Two common proxies for gun availability are used, the percentage of suicides with a firearm, and the"Cook index," the average of the percentage of suicides with a firearm and the percentage of homicides with a firearm."

"In simple regressions (no control variables) across 26 high-income nations, there is a strong and statistically significant association between gun availability and homicide rates."

So, if I'm reading this correctly, gun availability is calculated by percentage of deaths by firearm, and using that info they determine that gun availability leads to a higher homicide rate? Also no control variables? Why?

Using such source numbers, it's a foregone conclusion. If you use percentage of firearm deaths as a proxy for gun ownership, you will by definition have a strong correlation between gun ownership and deaths.
You're describing something else "well-enforced set of top-down policies" is how things are structured. You can get that from a king's brutal enforcement of divine law.

Technocracy is how to chose who runs things: "is a system of governance where decision-makers are selected on the basis of technological knowledge. Scientists, engineers, technologists, or experts in any field, would compose the governing body, instead of elected representatives. Leadership skills would be selected on the basis of specialized knowledge and performance, rather than parliamentary skills.[2] Technocracy in that sense of the word (an entire government run as a technical or engineering problem) is mostly hypothetical." https://en.wikipedia.org/wiki/Technocracy

Critically, having someone technical in charge based on an election is not a Technocracy. It's related to Monarchy/Democracy just replace by birth or by election with by demonstrating relevant technical skill. Knowing how to build a CPU for example is not relevant to setting health policy.

PS: The closest we have come is probably a small hunter gather group lead by a group of the eldest. As they are selected based on their skill in survival. Though presumably they had far fewer regulations etc.

The big advantage that RISC had back when it came out was that you could fit an entire RISC core on a single piece of silicon, something that isn't really applicable in the modern day.

Right now the big advantage of RISC in the high end is ease of parallel decode thanks to instructions always starting on 32 bit boundaries. Which is maybe a 5% power advantage at most. 64-bit x86 has lots of historical baggage and the people doing 64-bit ARM were clever so they're actually about equal in instruction density. It was an advantage to have fewer instructions back in the heyday of RISC but it isn't any longer and both ARM and x86 have tons of different instructions.

When you move down from high power OoO cores to in order ones then having 32 registers instead of 16 becomes more of an advantage and the benefits of simpler decode become more significant too.

This can be a wonderful habit, or it can create cranks. As you mention, Feynman used it to great success, but he was Feynman. I had a few classmates in graduate school—I nearly was one, until my advisor set me straight—who couldn't make any progress because they couldn't take any results for granted; they wouldn't do anything until they could prove everything. This is intellectually admirable, but a sure recipe for stagnation (at least for me and these classmates).

I know. But if there is a hype bubble, it cashes out to have a very compelling story with which one can explain the world.
Reading this I thought the same thing. Then I remembered one of my high school teachers telling the class that Bertrand Russell wrote a multi-volume book with the goal to prove that 1+1 = 2. At that point I realized that you don't need to work in abstract algebra in the high school mathematics curriculum, but rather you need teachers who have a deep understanding of mathematics. Unfortunately given economic reality that's hard to achieve in the present day.

It's a very important goal, but if you believe that drug use itself is corrosive to the culture and prosperity of a people, you might prioritize overall drug use.

Let's take a hypothetical. Do you prefer a society where 30% have drug problems damaging themselves and their families, but there are very few overdose deaths and diseases among that 30%? Or one in which only 5% have drug problems, but there many more deaths and diseases among that 5%? I don't think there's an obviously right choice.

Ideally we can thread the needle and lower drug usage in addition to reducing the harms associated with it. That's the trillion dollar policy question and I don't think anyone has solved it yet.

Why? Search is a service provided by a company trying to make money, just as a retailer.

Just because it's an invaluable service now core to using the internet, doesn't make it a public utility.

Here's the actual difference:

If Google started blocking Amazon search results there would be an upoar.

Amazon has blocked selling certain Google items, and there is barely a whimper.

Here's the other difference: When GOogle shows Amazon search results, and users go through those results to make an Amazon purchase, Google gets a cut. That's how e-commerce works on the internet.

> Does this really require knowing abstract algebra? Seems obvious to anyone doing any sort of multiplication that if the output is 0 then one of variables/functions has to be 0, if it is nonzero then the variable/function can be anything but 0.

Since you mention them specifically, it's not true for functions: multiply the function that is 1 for positive numbers and 0 elsewhere, by the function that is 1 for negative numbers and 0 elsewhere. (One can even produce continuous, or even smooth, examples with only a little more work.) A more traditional example is that it's not true for matrices: multiply the matrix ( ( 0 1 ) ( 0 0 ) ) by itself. (I just noticed sedeki https://news.ycombinator.com/item?id=15860883 pointed this out a few minutes earlier, noting that, for example, neither 2 nor 3 is congruent to 0 modulo 6, but their product is.) What I mean to say is: it often doesn't require knowing abstract algebra to think that things are obvious, but it may sometimes require knowing abstract algebra to figure out whether obvious things are true.

(Also, the last sentence you quote:

> Yet it is not the case that if f(x) * g(x) = 4, then either f(x) = 2 or g(x) = 2.

is, I would say, the important operational point. My students, especially in calculus, love to use this style of reasoning, even when specifically told that it doesn't work—although sometimes they change it (usually to conclude that f(x) = 4 or g(x) = 4). As Twain might have approximately said, it's not what's obvious that you don't know that gets you; it's what's obvious that ain't so.)
Using incognito mode and not logging in to sites should be enough to remove most of that information you list.

Incognito mode shares information across tabs, and until you restart it. I think there are extensions that will make the identity change per tab (at least for Firefox if not Chrome).

If you don't want cookies shared over time within a tab you can disable the cookies, but this will render much of the web unusable.

IP address is the tricky part. TOR will work for this. I think there are VPN services that let you periodically reset your IP.

So, yeah, we can definitely do this for ourselves. The tools already exist.

Market share.

Amazon has less than 20% of the consumer electronics market share. Google has more than 80% of the search market share. It makes a real difference. No one cares if a small store with no market share refuses to sell something. Amazon is big enough that there's some concern, but 20% to 80% is a big difference.
