I don’t know the reasons To this. But I but would comment that when it comes to bluetooth, once again Apple has shown that they “get it” with airpods, the major feature To me is simply that they remove most of the incredibly annoying issues with Bluetooth that other products just seem to not even notice.

I have had other bluetooth headphones where sitting down at the computer means I first have to go find my phone and disable Bluetooth to use them with my computer. Where I have to go through the menus to connect them every single time For every device. But AirPods “just work”. Sit at my computer? They connect straight away no action from me, just my magic when I put them in. Walking around with my phone? They just connect (and show battery status) just when I put them in. It’s simple and effortless. That couldn’t have been an easy feat considering everyone else on the market are failing at this and have been failing at this for pretty much every Bluetooth device for more than a decade.

I’m sorry to say it, but the author is wrong in his central point that this was not a failure of prediction.

Well, I did. I started hedging against a stock market collapse on Feb. 19 and sold half my tax-exposed holdings on Feb. 28, incurring a really painful skin-in-the-game tax bill.

In the first week of March, I made a very alarmist post on my personal social media profile, announcing to all my contacts a call to institute quarantines, work-from-home, reduce public transport use, face masks in public and outlaw crowds until control of the epidemic control was evident. This was after reading anonymous first-hand accounts from doctors in Lombardia, following the obvious exponential trend of spread in every country hit and watching China shut down the economy of a meteopolis. At this point, it was clear what would happen. Maybe not if you struggle to disregard opinions that don’t match the data, but that’s not the point.

I never take these kinds of defensive or alarmist measures in times of peace. It was a one-time thing, and I felt like a complete freak for going against the consensus and sticking my head out among educated and respected friends. Had the worst FOMO of my life regarding the tax bill and stock market hedges. But I was right, I am not usually wrong and this is not a post-fact rationalization. This was predictable in early March, at the latest.

Maybe the author is right that society would have been unable to heed these warnings, but that’s practically a tautology, given that we know how things played out in most Western countries.

My family heeded my warnings, and stayed safe through the most critical phase when the disease was rampant but not obvious.
Over 700 Malicious Typosquatted Libraries Found on RubyGems Repository
Similar methods exists for all kinds of engineering problems, like architecture (form follows function), roofs, bridges, city planning, or just the economy.

The optimal form is always an optimization problem. Just define the constraints.
Maybe the most famous example is Gaudi calculating the form of the roofs of the Sagrada Familia, and then Frei Otto for the Munich Olympics. City planning is easier as their is no gravity, just more constraints. Think of SimCity run in a simulation with feedback loops.

The best planning approach is always prolog-like. Define the facts and rules, and the forms will fall out eventually by itself. Then optimize the solutions iteratively according to cost functions. It's called OR, operations research.
I did a lot of that with free-forms, also even simply office layouts, when I worked as architect. We even sold CAD programs to special manifacturers to design a good roof or other free-form shapes. Like for Disney.
Someone might have jumped that hurdle but the point is it circumvents that class of hurdle. What about the next framework which doesn't have bindings? What about leveraging existing Pytorch code that's written in Python?
The part titled "the science bit" on their homepage is completely unscientific.

Am I looking bat the wrong place? Can someone explain the math used here?
Not a physicist but I can answer this.

Antineutrinos have opposite lepton number compared to neutrinos. Lepton number is preserved by all particle reactions[1] so for example beta decay must produce an antineutrino (L=-1) in addition to an electron (L=1).

Antineutrons also exist. Neutrons are composed of three quarks, uud (u has charge 1/3 and d had charge -2/3), while antineutrons are composed of two up antiquarks (charge -1/3) and one down antiquark (charge 2/3). And as in the case of neutrinos, neutrons have baryonic number 1 like protons and antineutrons have baryonic number -1 like antiproton a. Hence, for example, a beta decay will always turn a neutron into a proton and an antineutron into an antiproton (though the latter is theoretical).

[1] More precisely there is a lepton number for each generation (electron/muon/tau) and all three are separately preserved.
For me the worst isn't even that the UI composition/presentation is bad. It's that the performance of these interfaces is getting monotonically worse over time. No one wants to take the time to learn the hard native UI development processes, so we just wind up throwing some shitty angular SPA application into electronjs and calling it a day.

Those of us with non-sloth-like reflexes now have to experience torture as every keypress or mouse click takes an extra 50-100ms to register. Microsoft even figured out a way to make things that didnt use to run like shit run like total shit. Of all the things, mspaint is now somehow a little bit slower and more annoying to work with. I don't know how they managed that one.
The data-point for the elephant in the room:

Aérospatiale/BAC Concorde - $169M
150 passengers. Cruising speed: Mach 2

The Concorde was a thing of beauty. Massively expensive to produce and run, and fuel inefficient, it was a passenger airliner that could outrun fighter jets. Fighter jets of that era could get to mach 2 using afterburner, but that's especially fuel inefficient so they could only keep up for 15 minutes or so. The money that went into the program (which is estimated in the neighborhood of $10.3 billion) was later recouped in the form of expertise that went into building Airbus.

A lot of time has passed since 1965 when the Concorde was first produced, and the improvements in technology (especially for materials) since, will hopefully allow the economics to work out better this time around. But with the rise of lie-flat seats and personal entertainment systems, flying business class is "good enough" compared to the surcharge that flights on the Concorde cost, so I'm cautiously optimistic.

Taking 3 hours instead of 6 is better, but still not low enough. Add getting to/from the airport, and checking into the hotel and all that, you're still out the better part of the day.

The really pie-in-the-sky way to travel is if a certain reusable rocket company ran (exorbitantly expensive) passenger service. Moscow to New York in 30 mins, or Moscow to London in 15.
It's optimizing for an average of shots from more or less arbitrary locations, so it's not necessarily a perfect parabaloid.
Now you are confusing maths with Physics!

Physics is about describing the fundamental behaviour of reality, and so it is rather natural to think of the work as a process of discovering how to best describe it.

What maths is, is harder to say. Certainly it starts by just picking a set of rules, thus inventing a new thing with some properties.

But, much like how a developer might ”invent” a program that solves some problem, but only ”discover” the bugs they wrote, so the mathematician too must spend a lot of time working with their newly created object to ”discover” what it really does.
Bluetooth Low Energy is this replacement – it's a completely different standard.
It's not hard to argue in favour of temporary emergency price controls using Econ 101. The field already makes a big distinction between the short-term and long-term, defining the later by the time required for new investments in production. That distinction is the crux of the shortage, so it seems it's with the bounds of what an introductory microeconomics course could handle.
You could call it a fairness doctrine, or something ;)

Yeah, it's irrelevant if you buy prebuilt.

If you build it yourself, how do you know how to spec the system? You either waste resources by overspeccing it or you waste money by paying for something that can't run at full tilt on your system.

And if you care about quiet and cool computing, you're screwed even more. A CPU that will run until it hits thermal limits means maxed out fan speed. I don't want maxed out fan speed.

Are there any CPU coolers left that allow you to set a fixed speed manually? :)
Increasing thermal inertia in our housing is a great idea. It saves energy.

But: we need to build low energy housing to manage climate change. That means there is very little waste energy available. Last house we built was 230m2, family of 5, had a total energy consumption, including everything from heating to water to home electricity, sitting at 8000kWh/y. That's in southern Sweden (N58deg).

There is no relevant amount of waste energy available.

This is the kind of housing we'll need to meet future energy targets.

That looks good!
Most comments are quite negative, but I think an important reason is that the "flat" style looks pretty good on a screen and feels "native" to the digital media in a way watercolors or pencil or oil paint just doesn't. It is basically the natural evolution from simple icons. Sure most of it is generic and derivative, but this is true for any style.

It is typical that a new media try to emulate older, more prestigious media. Digital lack the physicality, so there was a long infatuation with trying to make it look more "physical" - shadows, texture and so on. Now it seems the tide have turned and print magazines try to look more digital.

Mark Rober is an interesting character. It feels like he pitches himself as a crazy inventor guy but it seems like he’s more akin to the head of a design laboratory that employs many other talented people.

It’s not like he doesn’t acknowledge the other crazy-inventor people he commissions though, and I certainly don’t mean to paint him as a fraud.

When he says things like, 1m45s into a video on a steerable bowling ball “in the spirit of full disclosure this is all down to [named co-collaborator]’s work” it feels like that use of full disclosure in the sense of I would rather not reveal this but I am legally obliged to.

No offense to Rober or that particular collaborator. For all I know, he just didn’t want the publicity. Rober is very good and it’s almost like I feel aggrieved that if only his style was ever so slightly different he’d win my complete instead of partial admiration.

Citation needed. And no, aquarium cleaner dude is not what I mean by "citation".
I'd like to know if there was any evidence or indication of the value of HQNN before a certain president started spouting it. AFAIK the only reason we're talking about it is because he did. If that's so then there's no reason to pick HQNN as being special over any other drug. I suppose there's that very dodgy french study, perhaps that's what started it all off.
With all due respect I find this view shallow and very incomplete. Open source is not a set of licenses, it’s people, companies, code, etc. The only reason to ever talk about open source in terms of just what the licenses say alone is if you are dealing with legal issues. The licenses themselves are nothing more than a tool used to facilitate open source within the copyright system.

Again... legal obligations and morality are two different things. Morality is subjective. You can’t encode morality or subjectivity to that degree into a license. You can’t legally enforce the spirit of a community or movement.

Obviously GPL strikes some kind of balance by trying to encode a legal provision that forces collaboration, and that’s cool. But GPL is a trade-off. It creates legal problems that don't hugely benefit anyone. ZFS on Linux is a perfect example of where GPL hinders a perfectly in-spirit action that would mostly be to everyone’s benefit.

Whether you prefer erring on the side of caution or on the side of flexibility is more of a personal thing. I tend to use a BSD license, and I don’t personally care what happens to my code. Still, that doesn’t mean that I think there aren’t ways to abuse that where someone benefits and open source loses.
Yeah ok, not sure about that. I basically try the online shopping functions that the supermarket/drug store chains offer that I would normally enjoy visiting in person. (But I have to plan in advance for that) Also I'm trying Hello Fresh soon.

That is nowhere close to how ruthlessly they crushed competitors well before that. Microsoft are why you've probably never heard of Supercalc, Lotus/123 and WordPerfect. All superior products in the 80s and 90s, all crushed by MS strong-arm tactics of forcing PC manufacturers to sell machines with Windows and Office pre-installed.

They even destroyed companies they weren't even competing with, but thought they _might_ want to later! All MS needed to do was issue a vague press release that they were working on a competitor to [some successful software product] and all the customers would hold off on purchases until the original (successful) company went bankrupt. Many times MS never ever released anything, leaving everyone worse off.

So yeah. They seem nicer now, but they climbed over a lot of dead companies to get here.
Basically exactly the same kind of "evidence" as what we have now for remdesivir. Some patients got better while on it, but because there was no control arm we don't know whether they'd do worse (or better) without the drug.

I’ve always thought it would make sense to attach specific penalties to this type of legislation. Something akin to “If you lie on an application, your loans won’t be forgiven and you will need to pay a 50% penalty. If you’re a bank and you knowingly facilitate this fraud, you will lose Federal backing for the loans and your employees and executives will be subject to minimum 1 year sentences in Federal custody.”

It’s unfortunate we live in such a weird carceral state yet white collar crimes that would probably be the type most deterred by the threat of prison are so rarely prosecuted.

The plan might face problems from time and economic perspective. Reaching herd immunity level might take way too long, even years, during which time most other countries are opening back up using mitigation strategies. Sweden meanwhile might be under travel restrictions imposed by other countries to ward off second wave, hindering their economy far longer than other countries.

It really does seem like a gamble, and I don't appreciate governments taking gambles.

That’s spot on, and a great comment on times of crisis in general. In times of peace, leaders in most fields are not chosen for their ability to quickly make the best decision from uncertain data.

There are a few exceptions, e.g. some military commanders with real field experience. Some stock market speculators. A rare few skilled politicians. But the vast majority know the tools, rituals and heuristics of their trade, and apply them blindly. This normally works well. But during times of crisis, when knowledge is uncertain and data changes rapidly, it leads to huge mistakes. Like clockwork, one after the other.

I could go on and on about examples of this from different fields, observed only during the last 6 weeks.
