>Of course the chosen panel of reviewers is supposed to remain anonymous.

If only! My professors were quite adept at figuring out who the reviewers were, especially if they're someone from their "cabal", because every investigator has their own grammar and language style and whether professors are good at science or not, they are most definitely really good at English (gotta write those grants perfect!).

Typical practice nowadays, is that these journals would choose two reviewers from the suggested list, and get one other by themselves just to try to be unbiased. Hence, the fate of the paper would reside on that single reviewer (my experience has been that the "suggested" reviewers will never reject the paper unless it's absolute shit).

Perhaps the journals should check the citation history between the suggested reviewer and the author to make sure they are not mutually citing each other and stroking their backs.

No news here. This 21-year-old college report [0]from 1998 (Porrello, cites include 1993 Leveson, Nancy G., and Clark S. Turner.) has -a lot- more facts without the hysteria. It states:

"<b>One</b> programmer, over several years, revised the Therac-6 software into the Therac-25 software (AECL has not released any information about the programmer or his credentials)."

[0] https://web.archive.org/web/19980201101244/http://cobra.csc.... - "Death and Denial: The Failure of the THERAC-25, A Medical Linear Accelerator"

Previous Therac models had hardware interlocks to prevent some modes; they were removed in favor of software for the 25. No doubt there were some engineers who knew more about this.
I haven’t made any effort to analyze this for real, but:

A circuit to drive a tungsten lamp at variable brightness off AC is cheap (a TRIAC and its driver) but has crap power factor. I imagine a MOSFET to drive the exact same tungsten lamp from DC at a few hundred Hz PWM would be almost as cheap and could be filtered to have a clean input waveform. (Or it could be driven above 20kHz to eliminate the annoying audible buzz that tungsten lamps make.)

A big LED driver (AC to DC, constant current or constant voltage plus some dimming mechanism) is not particularly cheap, and the nice ones are largeish. A pure 24V “dimmer” (12-48V in, same voltage out, adjustable PWM frequency, and DMX controls) can be had quite cheaply with excellent performance. A constant current driver would be more expensive, but a DC-input driver ought to be smaller and less expensive than a comparable AC-input driver, especially if you care about power factor and inrush current.

(Common commercial AC-input LED drivers often have godawful inrush current, because they have big filter caps to get good performance, and they don’t spend the extra money on fancy circuitry to limit the inrush current. This means that you can’t actually put 20A of driver on a 20A breaker because the inrush current will trip the breaker. With DC input, a much smaller filter cap should give comparable performance.)

Anyway, this is all mostly speculation, and economies of scale matter. But those DC DMX dimmers really do exist.)

We known that machine learning gets attention of physicists these days, and although some of these applications look unrealistic or far-fetched, it sees to me from your description that condensed matter physics can be attacked from this direction, and it might be feasible.

You start with 1D problems, move to small 3D volumes, and build from there. ML is good at "interpolating" or guessing what the answer must be from a given input. Maybe, one will need many nested levels of ML models to realistically simulate a solid-state material, but this is not entirely impossible, I think.

If such an ML simulation can be done reasonably efficiently, then likely there could be a theory that can be formulated in terms of equations, approximating the "theory of everything" with sufficient detail.

> In fact, increased competition leads to reduced profits (at least in the short term), making this a "negative-sum" game.

I'm not an economist but I've never heard of competition described as "negative-sum." It's zero-sum because the consumer wins.

"Negative-sum" would be a nuclear weapons manufacturer profiting off blowing up half the planet. The manufacturer might have made money, but overall everyone else loses far more than the manufacturer gained.
I thought you were sarcastic with your first post. Seeing this one made me sad to see you were actually serious.
In what sense are they power horses? Under ideal conditions maybe, so for geographically small countries that's nice. For larger regions like the US most of our improvement in terms of emissions has been driven by a mix of increased efficiency within specific consumption types (such as cars) and a shift from coal to natural gas which ultimately is also a matter of co2 efficiency.
You make me sad, but somehow, it is a truth.

Yes, too many mathematicians write about areas of mathematics that could be useful to others, without giving any motivation, or any hand-waving explanations, or the critical distinctions that make it a useful approach.

There is a barrier of communication that (most) mathematicians don't want to take any time to overcome. Often, the opening is enticing, then it's straight into lemmas, formal language, and citing of famous results by name. Their slight inclination to explain it to others dissipates in the first paragraph, then it's off to the races to impress their peers.

This is easy to see on Wikipedia - most mathematics articles are utterly useless to any non-mathematician who wants to get a general appreciation of an approach to see if it could shed some light on their problem.

In almost all cases, it is better to read domain generalists coming the other way into the higher mathematics.

So what do you do on the weekends?
James Hague has a lot more Forth experience than I do. But I would initially write this function something like this:

variable v1 variable v2 variable v3
: vadd v3 ! v2 ! v1 !
3 0 do v1 @ i cells + @ v2 @ i cells + @ + v3 @ i cells + ! loop ;

Or, alternatively:

0 value v1 0 value v2 0 value v3
: vvadd to v3 to v2 to v1
3 0 do v1 i cells + @ v2 i cells + @ + v3 i cells + ! loop ;

I mean, yes, you can make it a puzzle. But you don't have to. These versions will be slower than Hague's first working version and probably the second too, but all of Hague's versions are slower (with any Forth compiler I've used) than what GCC will give you for the C version. And what GCC will give you for the C version, even if it improbably manages to vectorize, is also a lot slower than what you'll get if you do your vec3 math on your GPU. So maybe when it comes time to rewrite the naïve Forth version above, because it is slow, you should just code an SSE assembly routine and skip the manual loop unrolling at the Forth level, or restructure the whole system to do the vector math on the GPU.

Or maybe not. James Hague is a smart guy and he's shipped a lot of code, in assembly, C, and Forth. But I'd like to understand where my reasoning is going wrong, because I can't see it.

My perspective on Forth is that it's the thinnest possible layer on top of raw machine code that gives you all the fundamental mechanisms for improving your leverage. You need structured control flow, so it has IF ELSE THEN, DO LOOP, BEGIN WHILE REPEAT, and a couple of others. You need expressions, so it has an operand stack. You need procedural abstraction, so it has a return stack, which also serves to store loop counters. You need labels both to make your code readable and so that you can patch your code without overwriting parts of it with JMP instructions to wherever you have free space to put the patch code, so it has words. You need metaprogramming, so it has IMMEDIATE. You need run-time polymorphic procedure dispatch, so it has ', EXECUTE, DEFER, IS, and CREATE DOES>. You need namespace management, so new definitions hide old definitions with the same name, and you also have wordlists.

The problem with all these wonderful mechanisms is that they can become an attractive nuisance, as you futz around trying to find the perfect way to express your intent in the smallest, clearest amount of code, navigating the tradeoffs imposed by the sparse toolset. But you don't have to do it that way. You can just write simple, straightforward code that gets the job done with no fuss, and move on to the next problem. Forth lets you do that, too.

That said, I find it easier to get my code working in assembly language than in Forth, and I don't know if that's because I don't know Forth well enough, because Forth is inherently less practical than assembly language, or just because Forth somehow fails to fit my brain. My guess is that I fall for the attractive nuisances too often and waste my time with unproductive futzing. And that's what this blog post looks like to me.
There are no rabbits in the hat until late 2021 when 7nm comes to market. The 10nm process is completely broken. Watch how the majority of the roadmap is still on 14nm into 2021, there never will be a desktop 10nm for example. The Rocket Lake desktop chips in 2021 still on 14nm will drop down to eight cores to cram the new GPU architecture into desktop chips at a truly ridiculous 125 W. The Ryzen 9 3900 today does 65W w/ 12 cores and and you can easily squeeze in a 1650 into the remaining 60W.
You mean autarky, full economic self-sufficiency.
China is certainly big enough to operate as an autarky. The US used to, up to about 1980 or so.

This is a current goal of the government of China. It's called "Made in China 2025", and was announced in 2015.. "The goals of Made in China 2025 include increasing the Chinese-domestic content of core materials to 40 percent by 2020 and 70 percent by 2025.[5] The plan focuses on high-tech fields including the pharmaceutical industry, automotive industry, aerospace industry, semiconductors, IT and robotics etc, which are presently the purview of foreign companies." There's been some backing off on this from the government of China for PR purposes, but the big goals seem to be on track. Key items include a leading position in semiconductors and in aircraft. Semiconductors seem to be coming along well. In aircraft, the COMAC 929 is a medium-sized airliner with five prototypes flying. The engine is still imported, but an engine to replace it has been developed to the prototype level.

China already has the world's largest auto industry, so that's covered. Also the largest robot industry. Don't know about pharma.

Somewhere I'd run across a reference to the price of Adam Smith's Wealth of Nations (published 1776), in terms of a general workingman's wages.

As I recall it was on the order of about 1/5 a typical annual income.

This being in the late 18th century, 300 years after Gutenberg, with a well-established printing trade.

Books remained staggeringly expensive.

The progress made in printing over the course of the 19th century boggles the mind. As of 1800, typical presses were still made of wood, and though printing was generally in quarto or octavo pages (4-8 impressions per side of paper), a pressman might turn out 120 - 180 impressions an hour, and I believe that's generous.

The improvements from there were:

- Cast-iron rather than steel presses. Greater strength, lighter weight, improved efficiency and mechanism. Print rates doubled.

- Steam-powered presses. The pressman no longer was responsible for physically pressing each image.

- Rotary presses. Rather than Gutenberg's repurposed wine-press design, type was placed on a drum, with sheets fed through the mechanism.

- Electric drive. Like steam, but less steamy and more sparky.

- Web presses. Rather than individual sheets, a continuous sheet of paper. This is where paper-on-rolls came into being.

- Speaking of which, paper manufacturing was improving, and costs falling, all through this period.

- At the same time literacy rates were increasing from ~10-25% ~1700 to 95%+ by 1900. The people could now read.

- Typesetting enhancements, including oil-based inks, offset-type (where the print impression is a 3rd generation from the type originally used to cast the intermediate slug), linotype, multi-colour presses, improved engraving (for images), and eventually photo-lithography.

By the end of the century a high-speed electrically-powered Linotype web press could achieve a million impressions an hour or more.

Compare with webserver hit rates and their improvement from 1990 - 2020.
> But I doubt anybody will get the costs down enough to make them viable

[citation needed]

This was discussed recently and I really down understand the immense skepticism exhibited on HN (and in general) towards nuclear energy. Sure it's expensive now, but it's been misregulated into a pulp and all extant nuclear reactors are using decades old designs. AND you need to compare the cost of nuclear to renewables PLUS storage.

Don't kick a gift horse in the mouse. We had a great shot at getting off oil in the form of fission 60 years ago. Probably time to stop kicking it in the mouth and stop spreading misinformation.

Not exactly. It's a newly-released product that uses cream-of-the-crop components, but it's sold at consumer prices instead of enterprise prices. So AMD doesn't have a huge incentive to make this specific model first in line for the top-binned chiplets, and they had good reason for getting this product onto shelves two weeks ago rather than stockpiling inventory until after Black Friday.

In the broader scheme of things, AMD is having no trouble selling every CPU they make this year. That's due to a combination of generally high demand for CPUs, Intel's own production problems (which have caused Intel to prioritize other product segments over the desktop CPU segment where AMD's dominance is now clear), and AMD having to compete with many other chip companies that are placing orders for the same TSMC 7nm fab capacity—orders which now require much more lead time than they did at the beginning of the year.
They aren’t going to put these reactors in actual school gymnasiums. Give your head a shake.
Damn too late to buy AMD stocks?

It is unbelievable to me, the level of inaction from Intel's managements just sit there all these years with all the advantage and cash they have had, and watch all of these washed away.

Their response? More inaction.

Time to change.
"Superhuman" hyperbole aside, some people are demonstrably orders of magnitude more productive than others, and that's true for almost any field of work (depending on your metric, of course - but that's true for some of the metrics that actually matter to most people), and programming is no different.

Arthur Whitney, Fabrice Bellard, Linus Torvalds, Mike Pall are well known examples.

It obviously requires a lot of skill, and I agree with [0] that it also requires the skill to be selective - some problems require a lot of work for which there are no "better ways". E.g. Mike Pall, alone and in short time, produced a JIT that runs way faster than V8 (which probably already had 100x more man-months[1] of really really smart people at that point). This amazing feat is a result of Pall's amazing talent - but it was only possible (IIRC, he said so himself), because Lua, although it is essentially as dynamic as JavaScript, made a few choices that made it much more amenable to effective JITting.

Those not up on Canadian politics may not see what a Canadian would see here. These are three politically conservative premiers (think US state governor) that are often aggressive in their policies; cuts to social programs, anti-environmental, no carbon tax.

Knowing their policies it makes this out-of-the-blue project seem suspicious. I'm all for nuclear power especially if it's using CANDU reactors and thorium. But these guys ream the carbon tax or anything remotely environmental or socially progressive.

In Canada only Ontario (Ford) and New Brunswick (Higgs) have nuclear reactors generating electricity. Saskatchewan (Moe) doesn't have any reactors but they do have oil from the tar sands sharing it with Alberta on their border. Saskatchewan also has an abundance of uranium.

So colour me surprised and a bit suspicious these guys would push for this. Imagine if Trump suddenly swore off coal and wanted to build more solar and wind farms. Saskatchewan has more to gain than the other two premiers.
> you should be able to find a specific example where a minority vertically integrated platform vendor was declared a “monopoly” and specific remediation steps were enforced.

I already told you that the market defining process is a very case-specific one and big techs now are unprecedented. Why are you trying to find applicable prior arts on such cases? You asked how Apple can be monopoly on a market and I gave you one possibility which may or may not materialize due to its uncertain and complex nature. It's pretty hard to understand why you're being so defensive on this issue?

> If that were the case, every single console maker since the mid 80s would be declared a monopoly. Why hasn’t that happened?

There has been multiple antitrust lawsuits and investigations on Sony, Nintendo and Microsoft for their gaming consoles while their exercise of monopolistic power was nowhere comparable to Apple's nowadays. Why don't you google just 2~3 words before making such a false claim?
Nuclear submarines use highly enriched uranium as a fuel. That's not a practical thing to use in civilian reactors.
> It's zero-sum because the consumer wins.

That's not the traditional economic understanding of the *-sum expression either. In economics, competition forces efficiency improvements, which makes competition in cases where increased efficiency is possible positive-sum.
CANDU reactors can use thorium now with the current design.
Is there a reliable place to read more about the chems? I'm enticed but also a bit confounded by all the names.

I started last year using Swift Playgrounds. I was lazy and just pasted the input into a multi-line string. I had to switch away from Playgrounds after a couple of days because it would crash due to memory issues. It traces every line of execution and the intermediate values of all variables. I really enjoyed doing the challenges in Swift, but I did have to switch to using my Mac to do it.
