By making significant improvements in the material science and manufacturing of paramagnetic and diamagnetic materials. Magnetic bearings are limited by Earnshaw's theorem [1] which states (roughly) that you can't stabilize some regular magnets using only their charge - they have to dynamically respond ti each other or they'll all just fly off. Usually this is done with electromagnets and a control system like in jet engines but its expensive and difficult. The alternative is passive para/diamagnetic materials whose magnetic fields change based on the other fields around them but those are usually rather exotic and have to be precisely engineered. Without that stabilization, the bearings would be worse that useless since they would never be able to prevent the rotor from touching the stator.

I'd be very interested in seeing a few energy benchmarks not here, for example: energy to route 1B hits to a web endpoint, energy to parse a Json, energy to grab an auth token from a web request and forward to an auth server. Energy to forward 1M 1k files from the filesystem to the network, etc.
Something like 65% of all land in the UK is owned by the same families that owned it in the Norman conquest. 0.3% of the population today. Since 1066-1100.

The stat you quote may apply to some broader definition of “wealthy”, but for the true 0.1% - 0.01% it is truly eternal, and accelerating.

I agree with every point you've made in this thread, but bilbo0s has a good point about the optics. The vast majority of the voters do not understand economics, do not think systemically about "the greater good", and wouldn't follow an argument as abstract as "Most companies think their secrets are worth more than their competitors, but the only ones who are correct about that are giants like Google, who have every reason to push for trade-secret and non-compete agreements that restrict your labor freedoms and hamper your ability to get a better wage." There's a bunch of leaps of logic here that I believe and you believe because we understand competitive bargaining and have worked for Google, but which are completely foreign to someone who takes the first job they can get because they need money right now.

The fight for the 13th amendment was framed as "Slavery is evil. If you support slavery, you are evil too." That's the kind of moral argumentation that's simple enough that it can get voter support. There was a lot of economic jockeying going on and fights between new vs. entrenched interests going on in the Civil War, but all of that was hidden from the voters and largely written out of the histories. "Google spies on you" is an effective way to convince people to vote against Google's interests; "Google is commoditizing their complements and restricting their ability to make contracts to better their bargaining position" is gibberish to the average voter.

It's an unfortunate fact of life that nearly all good decisions are made for the wrong reasons. Sometimes I wish everybody could just understand markets and systems and vote according to their enlightened best interest - but they don't, and much of the fucked-upedness of the world comes from that.

> a counterbalancing mechanism

if the 4-wheeled version must also have the same level of acceleration and speed of picking up, won't it also need a counterbalancing mechanism? It just won't need the "balancing algorithm", but will need a way to balance the arm swinging out.

Also, the counterbalancing mechanism is written with software, so once perfected, it's "free" to deploy. The weight could be the actual batteries, so no added extra weight!

I am not sure why are you downvoted. There is a whole literature on mismanaged software/hardware projects and the culprits of those failures. Not in a small part the reason is often very bad management/design decisions.

Sure, go read the document. The title of this doc says "Samsung Relative Evaluation Report on S1, iPhone." I'm guessing that you never worked in technology or product engineering team?

Again, this internal doc was presented in the trade dress part of the lawsuit -- which Apple eventually lost. Both parties initially agreed not to present anything too confusing to jury because there were so many confusing overlaps between the design and trade dress parts of the lawsuit. Apple suddenly changed its mind at the last minute -- and the judges duly embraced Apple's evidence, but rejected Samsung's counter-evidence on procedural ground (untimeliness). A lot of Apple fanbois like yourself are just still confused about the trade dress and design parts of the lawsuit -- I could only imagine the confusion the internal doc had on the jury, but obviously in Apple's favor since Samsung's never saw the light.

Well, I think the reason they don't do that, and focused on the benchmark game (which I think is a good solution to their problem of needing representative sample, it just comes with its own caveats), is because much of that is often handled by libraries (possible written in C), code in the Interpreter or VM (also possibly written in C), or handled by the OS (in the case of connection handling and file access). Those are useful things to know, but don't inherently speak to the features of the language itself.

That’s the high level, however t has thousands of micro decisions each time, such as some situations where you might choose to create a hole to maximize a clear later, or when it is better to try to Tetris at higher levels as compared to clear the lower ones to avoid getting too high and therefore harder or impossible to manipulates the pieces properly.
What makes you think you know better than Apple what most of their users want?

I suspect you just know what you want, and why you want it, and are extrapolating from that to everyone else.
My guess is that it's not about quality but efficiency. Assuming the product works as advertised, someone might have pointed out that the power drawn is a lot more than the power supplied to the devices being charged (which to some extent is true for every wireless charger out there), and in a world where being sensitive to green issues is becoming the norm, this might have brought some bad press to Apple.
Well, according to this paper, ML can't do too well, unless you can use ML to solve NP-complete problems.

IMO it's got more to do with the fact that providing a power user feature such as "run a regex search on the closed captions" would implicitly define an API which needs to be maintained. It could complicate the backend forever or block certain optimizations even if the feature is used by a tiny percentage of users who'd be outraged when it's removed.
"Segregated" is an odd word choice. A historically disenfranchised group that now has the power to create avenues for themselves is what I would call equality. It is not a segregated space, but an act of empowerment.

Any UX designer just had a heart attack reading that. Yes having a bazillion knobs and buttons is cool for hackernews folks, but as a user, it's just confusing. There's a reason iOS is so popular, and Pixel devices are creating an iOS like simple UI.

> If you have 200+ rep on any one site, you can upvote on any other site

Yeah that's if you create an account there. Land on a random SE site from Google or from the Hot Network questions and chances are you don't even have an account.

The site looks exactly like Stack Overflow, but if I press the upvote button I get an annoying error and the person who wrote that answer doesn't get any points.

If I do create an account, every time I infrequently visit that site I'm met with an annoying banner to "remember to upvote". Despite the fact that I upvote Stack Overflow questions daily. You can't win.

Editing is the other major place where I feel this annoyance. On Stack Overflow I edit a ton of posts to correct typos, grammar, code formatting, and capitalization. But I can't donate my free labor on SuperUser or AskDifferent. I'm not going to add these minor edits to a review queue. So the sites are just worse off because of arbitrary site siloing.

> Each site has slightly different cultural expectations, and the belief - which maybe should be tested - is that that expertise doesn't cross between sites.

I'd very much question that belief. Maybe for the more esoteric sites, but a good user on Stack Overflow is going to be right at home on SuperUser, Ask Different, or any of the myriad slightly-different-but-mostly-the-same tech sites with slightly different focuses.
If you look at the Huawei controversy the intelligence community appears utterly convinced that these hacks are occurring. But the current trade war with China makes one wonder whether the threats are exaggerated or outright fabricated. OTOH, the negotiations also mean the U.S. has an interest in not disclosing details of actual incidents, to help China save face and also to preserve U.S. domestic markets as gambling chips--i.e. if it disclosed serious and pervasive attacks then nobody would buy Huawei, so China would have less of an interest in making concessions so sellers like Huawei can grow in the U.S. market. (Similarly, SuperMicro, Apple, and Amazon are American companies so U.S. officials have an interest in limiting the fallout to any actual attacks as long as the immediate threats are removed, which doesn't necessarily require the knowing cooperation of those companies.)

The last public statement from Bloomberg was that they were going to perform an in-house review. I'm just going to wait things out.

That said, the evidence for the viability and practicality of the alleged attacks has only grown. The alleged technique has already been demonstrated. See https://www.youtube.com/watch?v=C7H3V7tkxeA Nobody seriously doubts that China is motivated to perform such hacks, and we know that the NSA has performed similarly complex hacks (the cost+benefit calculus isn't always intuitive to outsiders). So whether it has or has not happened is really only consequential for the credibility of Bloomberg.
Yes, sort of, while in orbit. If your velocity relative to the spacecraft has a prograde/retrograde component, you'll desync the orbits - which means that after a single full orbit you'll not return to the spacecraft, but might find yourself many kilometers from it instead. Unless you or your ship's crew have some fuel available for maneuvers, you'll still die.
I find that "upstream" might be at odds with security/privacy, both in terms of funding and data collection (benign reasons being debug/crash data collection as well as "what and how do people use this")
The amount of Boeing hate is phenomenal. "scrap the plane" ! "require a new type certificate" "never fly in a 737 max, no matter what".

Boeing made a plane that conformed to all rules and regulations. As part of the design process, they made many, many tradeoff's. What kind of fastener goes on this panel? How often does this data go across the data bus? What material is used for this cable? Literally thousands of them. Not every one , by itself is safety critical; but many of them can turn out to be.

The MCAS design was not some engineer skirting the law, or wanting to kill people, or even disinterested in safety. It was a compromise design of cost vs safety; in hindsight it looks like the compromise was done poorly.

A 100% safe airplane weighs too much to fly and costs too much to build. This means every design decision has to take into account other things than just 'raw safety'.

They made a mistake. Even when you are not "moving fast and breaking things", people make mistakes. process adherence misses the mistake.

And in this case people die. Unfortunately, that is how we improve aviation safety. With the blood of passengers and crew. Not on purpose, not because boeing is greedy, but because people make mistakes, systems fail, airplanes crash.
This was not a single failure of the aviation safety system. N things had to happen for these crashes. And the system is going to fix each one of them, and do a humans best effort to change the process so it does not happen again.

i would fly a Boeing aircraft tomorrow (yes, a 737 MAX 8). Or an Airbus. They are both built and overseen by the best our world has to offer.

This is not the first design failure that has been the cause of an incident (or even a series of incidents) and it will not be the last.

I used to do web dev in chrome but installed ungoogled-chromium after that scandalous update where they forced you to login; in fact, after installing said update, I suddenly found myself "logged in" with a gmail address that I never even created in the first place (something like mycompanyname[at]gmail[dot]com). My trust in Google was already crumbling, this creepy move was the final blow. So far, my experience with ungoogled-chromium has been great, but I must admit I'm not really following up on the project (devs, userbase, security updates, etc).
It depends what you mean by "drop the whole thing." The latest reporting I saw with fresh conclusions is from the Washington Post in late November [0]. Essentially, Bloomberg sent out a reporter completely independent of the Big Hack article to ascertain whether or not it was accurate. Additionally, Apple did a secondary investigation to see if their senior director of information security had written any internal documents about the Big Hack -- no such documents existed, corroborating their initial denial. So both Apple and Bloomberg have taken additional steps since the original article was published. However, in terms of public statements, it does seem that they have dropped it.

Pertinent quotes from the article [0]:
"The goal of this effort, Elgin told the potential source, was to get to 'ground truth'; if Elgin heard from 10 or so sources that 'The Big Hack' was itself a piece of hackery, he would send that message up his chain of command. The potential source told Elgin that the denials of 'The Big Hack' were '100 percent right.'"

"According to the potential source, Elgin also asked about the possibility that Peter Ziatek, senior director of information security at Apple, had written a report regarding a hardware hack affecting Apple. In an interview with the Erik Wemple Blog, Ziatek says that he’d never written that report, nor is he aware of such a document. Following the publication of Bloomberg’s story, Apple conducted what it calls a 'secondary' investigation surrounding its awareness of events along the lines of what was alleged in 'The Big Hack.' That investigation included a full pat-down of Ziatek’s own electronic communications. It found nothing to corroborate the claims in the Bloomberg story, according to Ziatek."

Thank you Dang, I’ve read the Hacker News Guidelines multiple times in all these years I’ve been visiting this website.

As a non-native English speaker, I’m not sure what exactly in my comment above is considered “trolling” or “flamewar”. I’m legitimately scared that if I visit the US I will be a target and SWAT will not be careful enough to assess the situation, and instead will decide to kill me based on false information.

You have commented —many times— that repetitive comments like this in the website will get a user’s account banned, so from now on I will be extra careful with my comments as to not offend someone that may end up affecting my presence in the community.

Thank you for the advice.
It’s not a lack of control, it’s a different kind of control. Driven by algorithms and engagement metrics which appear to promote extreme content.

That difference is what has people worried because the political and social endgame is not yet clear.

Following up on this, why is it impossible to use just one coil that's more powerful? IIUC To transmit power, you just need a temporally varying EM field to induce current on the other end, so why not have one that produces enough power?

Honestly both of these are pretty easy claims to check. Not by manually looking and choosing recommended videos, but by following a random walk. If it is true that it all drags you into extreme videos, then if you take a random walk from any video, choosing recommendations at random, you would always end up down the hole in extreme videos.

In a lot of these experiments though, people explicitly pick the more extreme of the recommendations repeatedly, which of course will lead you down the rabbit hole.

> "Take your finely-calculated estimate and 3x it, both in time and money.

You should get really comfortable with “no”; Both saying “no” to bad fits, and hearing “no” from clients who can’t afford you."

Two quick thoughts:

1) "It always costs twice as much and takes twice as long" is a benchmark that has never failed me. 3x? Probably could have helped 25% of the time.

2) The key to freelancing or even being an agency is...avoid the time sucks, the bad clients. It's not finding grand slams or hat tricks. Sure those are good to have. But the killer is the bad ones, the really bad ones.
I'm a little surprised at where Erlang features in the list. I've never used it personally, but have heard so much about it being an amazing, performant language. I wonder why it's so time/energy/memory inefficient for the algorithms used in this exercise.
> Give your engineers a mandate to collect everything and anything, but don't tell management and legal the details so there's plausible deniability when people figure things out.

I've seen exactly that, sitting in at depositions of corporate defendants' management and IT staff. Nobody seemed to know the "big picture". IT staff knew what data they were managing, and how it was handled, but had no idea how it was used. Management knew business logic, but had no clue how to interpret data that they'd given to plaintiffs.

Many benchmarks have no TS implementations, TS/JS results are about the same except for fannkuch-redux which is about a zillion times slower in the TS implementation. When looking at that kind of massive discrepancy in similar languages with the same runtime, the guess kbenson made was a perfectly sensible one. The authors of the study should have examined that kind of crazy outlier more closely and it's, as pointed out, not that unusual when using the benchmark game as a starting point.
