The latter. Motor losses are in large part due to resistance in the windings. Going from 95% efficiency to 99% efficiency means 1/5 as much heat output per unit of energy delivered, which means if your motor is thermally limited (which many are these days!) you can push five times as much power through it without it burning itself up. Similarly, increased achievable magnetic flux means a smaller motor can achieve greater torque and power so it can convert more electricity into movement.

I think Web Components added a lot of complexity to the web platform again and we're finally hitting the breaking point where it has gotten to be too much. I don't want to deal with web components or the shadow DOM. I don't want more abstractions in the browser at this point.

On one hand, there are some use cases for this new complexity. On the other hand, it's difficult to see how the vast majority of say, React users, would ever benefit from this complexity, given that a lot of them don't seem to have problems that are solved by web components.

If we were going to focus on adding even more new browser features, I think it'd be better to focus on stuff that helps close cross-site scripting vulnerabilities, or provide better approaches towards anti-SPAM/anti-abuse than lazy, harmful remote attestation. (I mean hell, I'd love to see some very basic hashcash functionality as part of the browser; Personally, I think that would be an interesting idea for anti-SPAM, and nowhere near as catastrophically harmful as WEI.)
Spicy take:

Theory is shit (betraying my bias here). If someone released a paper that theoretically proved a material was a superconductor from first principles, I would ignore it, every bit as much as I would if it had the opposite results. In materials, experiment has always led theory. Theory has use in suggesting new angles to explore with experiment, but theory is fundamentally reactive: get new data, try to fit that data using known principles and math. It's simply not equipped to say whether reality is real or not.

Honestly, I think anyone who thought the DFT-based papers mattered at all doesn't really get how science works. The politics here is also worthy of keeping in mind: if a theorist comes out and says something is flat out impossible, he/she gets egg on their face if it turns out to be possible. If someone says it's possible, there's plenty of wiggle room to justify yourself if the material doesn't pan out (plus, if it does, you get lots of credit for offering the first theoretical explanation).

If you'd like a preview of this, visit your local library or some place that has a number of public computers which are frequently used by people with unknown identities, homeless, criminals, etc.

My public library, several years ago, implemented a 100% virtual scheme for the public computers. You log in and a freshly wiped and provisioned Windows virtual machine starts up. There is almost nothing in the box on the desk, except you can hook up some USB (with drastic restrictions). Otherwise, it's pretty much graphics and input traffic being exchanged over the network. A modern VT220. When you log out or time out, the VM vanishes and resets itself to pristine state.

By contrast, my community college had all sorts of places with academic computers available, and they were bare metal, although they had the same sort of clean-slate wipe when they were rebooted. It was sort of amazing in 2018 how many students still used these machines, even though there was a majority who toted around notebooks. A lot of students only brought a smartphone into class with them, and their eBooks and notes were all on the smartphone.

So I perceive a diminishing demand for public and academic computer labs, especially as the pandemic times have convinced so many people to stay home and not congregate in public, and the smartphone is a fully-functioning computer system. So let Microsoft do their worst. I already own one Chromebook and I love it. My next notebook purchase may also be a Chromebook. I'm thinking Framework or Pixelbook.

The Our World in Data link you sent lists total agriculture contributions as 18.4% of total contributions and livestock at 5.8% total contributions. At 5.8% it is still sizable but not close to being in the top 5 contributors.

Firmware, no unless you are ultra hard core.

But above that layer there are pretty big distinctions. Meta is fully on the record that they are all in on making Quest completely use OpenXR as the primary API to the point of deprecating the old Oculus proprietary APIs. They also actively pushing forward the latest WebXR spec into the browser on the Quest, and sideloading of apps in general is straightforward (although you do need a developer account to do it which is unfortunate).

Apple doesn't seem interested at all in open standards at the OS layer, so if you need to be happy with the fully walled garden and proprietary APIs to buy into that ecosystem. It's unclear if VisionPro will support WebXR in the browser it ships.

So in terms of freedom, you will get a lot more from Quest, but its definitely sad that this whole area of computing could end up being the first that has literally no true open platform available.
you are not wrong, the counter-prevailing theory is related to "Harm Reduction"

over centuries consider cities and their populace. Those who practiced strict morality laws led to slum cities where there was nothing but vice, whereas mixed cities past a certain size that licensed bars or theater or taxi-dancing or whatever the action was.. might have different outcomes over time for the population. The character of the police force and others wielding turf-territory might be different over time as well.

As the population grows its hard to imagine purity as a real reaction to public health, whatever your moral compass might be.

It’s worth pointing out that graphene literally is just a single layer of graphite. Making macroscopic objects out of graphene would mean layering them. So effectively we already have graphene in the form of graphite fiber (also called “carbon fiber”).

Graphite with zero defects and perfect crystallinity has the same properties as graphene. It IS layers of graphene.

(This is all essentially true for carbon nanotubes, too, which are just tubes made of graphene… maybe graphene is more chemically reactive due to the ends of the sheets though.)

Looks like they ported SIMH to an ESP32 to emulate a PDP-11, to run
the original tetris for the Soviet PDP-11 clone (Elektronica60), and 3d printed a mini VT-102 case to put it in.

And also 2.1 BSD..

FTA: "ESP32 was configured to emulate an PDP11-23 with 256K of RAM and a RX01 floppy disk drive, giving me 256KB of disk space for the operating system and game files. I used SIMH on my laptop to create a blank disk and installed RT11 onto it. Next, I took the Russian games disk containing Tetris and copied the binary over. That disk image would get flashed alongside the emulator to the ESP32. I didn't bother with the terminal as of yet, instead opting to just pipe the console of the PDP11 out of the debug serial port of the ESP32."

In the case of an incorrectly configured browser, sure, but definitely not mine - which is the whole point. Once freely offered, conditions can't be imposed on use. If you don't want my browser to render content as it sees fit, don't serve the content over a protocol where that dynamic is inherent.

The reason very few actually take that route is because they want to have their cake and eat it too: the openness of www/http but the monetizability of AOL-esque pseudointernet schemes. If a publisher wants to fuck off to corponet with blackjack, hookers, DRM and WEI they're more than free to do so, but traffic may not follow them. Mine certainly won't.
I live in a jurisdiction where sex work is decriminalised.

Trafficking does still occur. But it is a very small part of the scene.

The difference it has made to workers is huge. Once they were at risk from pimps, clients, and cops. Now if pimps or clients bother them they go to the cops, and the cops protect them. As they should.

As they do for shop keepers, plumbers, and computer programmers.

Make no mistake: Having a law against sex work encourages, and subsidises, trafficking.

> Firstly, it's a human rights issue, people ought to be able to engage in the commerce of their choosing with only reasonable restrictions

You’re starting with a libertarian premise most people don’t accept. The vast majority of the world accepts that it’s proper to restrict individual freedom even to protect people from themselves. Society has a role to play to help people make good choices and to make it hard for them to make bad or dangerous choices.

Also, you’re incorrect about the prevalent morals. Even in the US, women—who bear the lion’s share of the cost of prostitution—oppose legalizing by a large margin (50% to 30%): https://www.vox.com/2016/3/11/11203740/prostitution-legal-me.... And of course the overwhelming majority would still say it’s a bad or immoral choice, even if they agree someone should be allowed to make that choice.
> By legal definition

How's that?

Like, if McDonald's unknowingly sells a Big Mac to a hungry sex trafficker, have they facilitated sex trafficking? What if they do know he's a sex trafficker, but he's not currently dragging any women behind him with chains? Does he like have to be in flagrant possession of captive victims for it to be "facilitating"?

The legal definition, such as it is, is lame and rather loose. And besides, prosecutors routinely twist and stretch these definitions and judges rarely rebuke them for it, let alone shut it down (at least at the district level).

"Facilitating X" usually means that the defendant associated with the criminals, was vaguely aware that they committed crimes, and didn't refuse to do business with them (or in some cases, that they didn't become vigilante police themselves and investigate to be sure that the customers weren't criminals).

I'm reminded of a man prosecuted because he was selling little plastic vials with lids out of his dollar store. As he realized how popular they were, he ordered more... until at one point, he sought out a local manufacturer to make the things so he could reduce costs. The product was popular with crack dealers or something.

He was prosecuted on a "facilitation" charge of some sort. The idea of "facilitation" in regards to crime probably needs to be abandoned.
I would say yes, but I'm not sure I could articulate my argument very well. I don't think that they explicitly care about it, i.e. "control of our employee is $x which we accept as a cost of doing business". I think it's more indirect, more secondary, like it's a result of other more surface-level concerns. For example, "we need employees in the office so that we can make sure they are working so that we are ensuring we get our money's worth", which possibly has effects that mirror the 'nebulous notion of control' we're talking about. I think your comment is correct in a literal sense. Doubtful anyone is sitting at the top of a tower rubbing their hands together, scheming, trying to establish/maintain prison-like employment conditions.

Developers are hesitant to upgrade anything that's not being actively developed as updates can break things and automated testing either doesn't exist or isn't sufficient. Knowing when it's safe to ignore an update is also hard. Many vulnerabilities apply only to specific configurations, so you'd need to know review the description carefully, then track (somehow) that why you think you can skip it.

Dependabot specifically handles updates in a very lazy way. It submits a PR per dependency, so you'll often find 5-10 open PRs that really should be a single 'npm audit --fix' patch or similar.

My approach is to have great automated testing, then trust that updating dependencies is safe if the tests pass. There's still danger here with malicious dependency updates, unfortunately.
In the observations, this sample they tested did not exhibit the Meissner effect at room temperature. Which means it’s not the same thing the original team discovered?

The random jumps in the resistivity around 250 K suggests that there is very bad contact resistance or a possible alternate current path. The drop in resistance doesn’t look like a typical phase transition (it is very broad in temperature). My guess would be that the voltage leads are not very well connected to the region of the sample that the current is flowing through. This could actually give a drop in the measured voltage (and therefore “resistance”) even though the actual resistance is increasing as the sample is cooled. It would be interesting if they also included two-point resistance across the current leads.

Indeed, judging from both words & (in)actions, I think we can safely conclude that they don't.

> At the limit, I think the performance benefits of rust are pretty clear. The performance ceiling of rust seems to be pretty unambiguously higher than that of Go, Python, C#, javascript, etc.

Not to be pedantic, but "at the limit" performance is not a very good metric. Programming is an engineering exercise, so IMO performance delta per unit of development work is better characterization if we are comparing programming language.

At the limit C# supports inline assembly, so at the limit it could be match rust pounds for pounds with enough efforts, but that's hardly a useful comparison.

In general, a lot of the modern performance differences between programming languages is caused (from the programming languages perspective) by the object model each programming language use. Python/Javascript are in a class of their own and i don't think belong in performance conversation against statically type languages.
Can't comment on go cuz i don't know much it.

On C#, the memory model can be surprisingly close to rust. The combination of typed IR for efficient monomorphization + the the ability to use stack allocated struct, mean that C# code can be quite close to rust code. And then the differences are mainly a consequence of LLVM backend vs ruygenJIT or AOT.

To say nothing of the advantage that a GC can have by having a global view of memory allocation/deallocations.

Added to that the fact that the time a rust eng. is spending modeling his ownership relationships and converting then into something the borrow checker can/accept could be spend improving C# perf further.

> Can you give some examples of those tools? The “first language” I mentioned above was C. What equivalent does C have to rust’s memory safety? Or C++ for that matter? Are smart pointers in C++ that ubiquitous and good that memory corruption is a thing of the past?

I am not too familiar with C, but i don't a think any new tool is needed : wrap all the unsafe operation (naked array accesses, allocation etc...) in a safe API and only use the safe API...

In C++, its trivial to avoid memory unsafe operation between smart_pointer, &reference, for_each for iteration etc... etc... Manipulating raw memory in "modern" C++ is mostly a choice than a necessity these days.
