FWIW, I recall being shown some of these new gestures (cut and paste, undo) in post-update iOS 13 splash screen of some kind.

By contrast, when I hardware swapped from XS to 11, nothing prepared me for the loss of formerly oh-so-intuitive 3D Touch. I’d read about it, didn’t realize how second nature it had become. I often saw others struggle with or unaware of 3D Touch, so my guess is Apple metrics showed it wasn’t as widely used as they’d hoped. The other positive is consistency, as I occasionally attempted 3D Touch on iPad or old phones and felt stymied.
Twitter is so anti-Trump, I’m not surprised they’re doing it to other countries too.
Americans on average do not want denser housing. It's not part of their culture, they don't see the point, they want a backyard, and they don't mind having to drive all the time.

I'm pretty sure that even the people benefitting for the wealth cities produce would prefer not to live there, and I think the development of rich people's houses along the CT coast attest to that, they try to balance the wealth of the city and low density housing.

In this case it didn't work (rubber hose?) but the longer the chain the less likely you are to be exposed. The original hitman can testify that YOU paid him to kill John. The fifth hitman can only offer hearsay, that he heard from the fourth hitman that the third has said that the... ;)

I think the more correct statement is that “containers” (i.e processes running with some kernel namespacing features) don’t replace the need for existing security tools like seccomp, SELinux, apparmor. Namespacing is just another tool in your arsenal to help create some logical separation between security domains but you still likely need more to be sure that the separation is enforced.

“Docker”, the tool that is slowly acquiring the ability to natively use all of these security tools and apply them to the containers it launches is/will be a security platform.

Well, you can do that reasoning algebraically as equations on the coordinates. So you translate the constraints into equations. See https://en.wikipedia.org/wiki/Analytic_geometry

If memory serves right, there's a certain subset of geometry that decidable in that way. Ie you can just run an algorithm.

The manufacturer states 25-30 years for shingles, but it's rarely the case they actually last that long unless you're paying for premium shingles. I'm in Canada though, so perhaps the harsher weather has something to do with that. Regardless, in Canada at least, 25-30 years for shingles is not common; 15-20 is more realistic from what I can tell in my area.
Dense urban areas with mixed residential, commercial and retail spaces all within walking distance of each other are the antithesis of Le Corbusier’s vision of a perfect city. He would have been appalled by Singapore, if possibly less appalled than by Paris which he would have liked to raze to the ground and rebuild.
What are the power requirements for something like that? Since the stations are much less densely distributed than cell towers I'd expect you'd have to use a lot more energy transmitting if you'd hope to get any data. This needs to be light enough to attach to an eagle.

Yes. They pay little for fuel. Also afaik they do not use the waste heat. Though probably with the logistics train to some places the fuel can probably be expensive at times.

Denser human scale development is the real answer. Electric cars and rooftop solar is not going to solve the massive suburban sprawl crisis. You can thank the federal interstate system for that (effectively subsidizing land).

I find this difficult to believe. Chinese apartments are not sold furnished like you describe. They’re sold as bare concrete shells. Apartments like you describe are overwhelmingly rented, not sold. Usually when people buy a pre-owned apartment they strip it down to the concrete and redo everything.
Fuck this guy. He writes like someone wants to take away his toys. Here’s a newsflash, dear author: as a Nissan Leaf owner for the past eight years, I say fuck subsidies, too. I mean for me personally, anyway. Because I am so done with ICEs, I’ll pay a premium to not drive one of those rattling, smelly contraptions that my parents were enamored with (and myself, too, as a younger man). You know what’s nice? After I laid floor tile in the garage (man, why didn’t I do that 20 years ago?), we can now pull the car out, lay some yoga mats, use it as a yoga studio. But that only works if your car is electric, otherwise wait 30 minutes while the exhaust clears out (watch the oil spots, too). As just one example.

I’ve bought my last ICE, subsidies or no. I don’t represent the general public, but I have to represent more than a few.

But what is this guy afraid of? It reads like “you, sir! You, who (except for the in-dash system) are completely tickled with your Nissan Leaf! Don’t be happy! You should be miserable with your electric car! Why aren’t you miserable?! Look, here’s reasons your car is a bad idea!” In other words, this sounds like a guy who’s trying to sell me something, not inform me.

Morals for stories are usually conclusions drawn from a sample size of one. Aka the anecdote.

For this story though... 4 out of 5 people subcontracted to another hitman. First anecdotal story I've seen that could be statistically significant.
> Tan, who hired the original hitman, was jailed for five years, while Xi, the first hitman, was sentenced to three years and six months. Yang Kangsheng and Yang Guangsheng were sentenced to three years and three months, Mo was sentenced to three years

5 years seems grossly insufficient for premeditated attempted murder. If the man was actually killed, I'm assuming the sentence would have been far more severe, such as 20 years. It seems ridiculous that someone can get a 75% reduction in their sentence, just because they were incompetent in their execution.
50 years? I have noticed that slate roofs are much more common in the UK than the US but still I see majority asphalt shingles, curious what y'all call them, on single family homes built within the last couple hundred years.

I wish y'all had some more thatch roofs but I suppose given the history in London, driving to the Cottswolds to see a thatched roof is probably fine ;)

True, but when he offered $250+K he must've figured that killing him is worth it that amount. Considering that you cannot put in on eBay or Fiverr he took the offer.

This is simply a side effect of ill-disciplined programmers breaking ABIs whenever they feel like it. It's quite possible to maintain ABIs in the long term and upgrade and deprecate them thoughtfully, and if you do that then you don't need multiple versions of a library or service around.
Well, we are constantly replacing programmers by computers.

Think of eg compilers and interpreters. Thanks to them, perhaps you need only one guy to write software to solve a problem that used to take 10 people: 9 people replaced.

UK roofs are made and ceramic and slate. US roofs are made of asphalt. Mostly because asphalt is inexpensive (particularly due to economies of scale/lack of them on ceramic). Ceramic lasts a lifetime, asphalt can be taken out by one bad hail storm.

UK homes are made of brick. US homes are made of fiberboard and inexpensive woods. There's a reason why UK homes have lasted over one hundred years, and most US homes won't last 50. It is a consumer culture applied to homes. They're designed to be replaced completely.

Whereas the are such contemptuous people it is just as bad to have the converse. In my experience the median number theorist is like today's physicists in that they are
resisting consolidation in favour of elaborateness.

Traditionally, category theory was treated with much disdain especially by concrete mathematicians. The fact that hipsters now think category theory is cooler than combinatorics doesn't in my opinion warrant swaying again the other way—any kind of evangelisation is inherently fraught with personal agendas.

It could be that the specific examples that he gave are really justified. But I don't really see the point of being a warrior for concrete mathematics or being a warrior for abstract mathematics. I don't even see the two as different fields rather different processes. And as I said earlier, I have found combinatorialists to be more contemptuous than category theorists, hipsters aside.
Is $8000 huge? What kind of infrastructure do you expect to build with that?
I guess they just meant it as in "reading code," when in fact bat is better tool just for reading code.
The focus on “observation” in quantum mechanics is dumb and damaging. In quantum mechanics observation means something very different from what people assume when you use the word observation.

When you say “if we observe the position of the electron” people think: “we put an observer who without interring in any active way and he looked at the electron to see where it is”. What QM actually means is more akin to “if we take a 200 Ton bulldozer and force the electron into one or two positions and then test which one it’s in”.

The very issue arising from
Observer effects is that you cannot have the system in a single state where for instance momentum and position are both observable, and observing either means forcing the system into a state where the other is “uncertain”, that is to say that it will have a distribution of outcomes if you use a different 200ton bulldozer to observe this parameter afterwards. The uncertainty principle basically tells you that the technical requirements for a “position bulldozer” and a “momentum bulldozer” makes it fundamentally and axiomatically impossible to make a single bulldozer that carries out both “observations”.
We had to replace ours after only 15 years (and we should have done so earlier). The manufacturer's claims are suspect. Expansion/contraction due to the hot/cold cycle caused ours to crack (literally apart in some cases).
I guess it depends on what you mean by university level mathematics.

Terrence Tao definitely says that doing university math changed his approach to these problems. See https://terrytao.wordpress.com/books/solving-mathematical-pr...

Side note fyi... the "?mod=rsswn" appended to the WSJ url to bypass the paywall stopped working a few weeks ago.

People keep submitting urls with it (and this article's url also has it) so submitters probably don't realize it doesn't actually work anymore.

Also, disabling Javascript on wsj.com also used to work to bypass the paywall but that trick was blocked around the same time they blocked "?mod=rsswn".

One of the workarounds is to emulate behavior of googlebot but I don't think that's easily translatable to a simple modification of the url string: https://github.com/iamadamdev/bypass-paywalls-chrome/issues/...

I think you are right that a lot of Americans do not want dense housing. One thing we are missing, especially on the west coast, is good public transportation. Its not that I don't mind driving as much as that I don't have a choice. I'd love to take a train/subway to work or to the next town over or to the big city nearby - but those trains do not exist.
The same thing happens in Europe, most of the eco-related additional costs are actually regressive taxes that will mostly fall on the less better off. There are not that many media outlets openly discussing this, and the few people who actually do talk about it are painted as “wanting to destroy the planet” or worse.

They are referring to using cat to print out a file to the terminal. I'm not sure that's a "misuse", but personally I've never done it, using "more" or "less" instead. "bat" really is a replacement for more/less, only with additional features such as syntax highlighting in source code.
Man this piece contains so many obviously wrong and dishonest arguments mixed in with a defeatist attitude. It even manages to contradict itself.

It simultaneously argues that it takes 3x the number of workers to produce a battery pack as it does to produce a engine and then says that the switch to EV's will decimate jobs.

It claims it takes 100 barrels of oil to build a battery pack capable of storing 1 barrel of oil worth of energy implying that's a bad thing as if you use the battery once and then dispose of it. Good quality lithium ion batteries last for 5,000 cycles and Tesla claims their current battery technology should last up to 500k miles implying something like 15,000 cycles. A barrel of oil makes roughly 20 gallons of gasoline so if the 100 barrels of oil to make a battery pack is true that sounds pretty amazing to me.

On the mining thing Lithium mining is some of the cleanest mining in the world because you can extract it from water pumped in and out of the mine.

The list goes on.

Never believe that anti-Semites are completely unaware of the absurdity of their replies. They know that their remarks are frivolous, open to challenge. But they are amusing themselves, for it is their adversary who is obliged to use words responsibly, since he believes in words. The anti-Semites have the right to play. They even like to play with discourse for, by giving ridiculous reasons, they discredit the seriousness of their interlocutors. They delight in acting in bad faith, since they seek not to persuade by sound argument but to intimidate and disconcert. If you press them too closely, they will abruptly fall silent, loftily indicating by some phrase that the time for argument is past.
Jean Paul-Sartre
It feels like the author was exposed to the rhetoric of the web having been ruined by tech giants due to centralisation, and decided to write an article about that, expecting clicks and views, all without trying to first understand what the people behind such a rhetoric actually mean. I mean the article discusses the issue of a centralised web by stating the russian inference in the US elections. How does that illustrate the centralisation issue of the web platform, and how can a decentralised solution prevent that?

Also the article is only accessible through a subscription, so I couldn't finish it, which is ironic because this is exactly what's broken with today's web.
It is done using symbolic algebra, not just assigning specific coordinates if that's what you're asking.

Let's say you're given three parallel lines. You can put your x axis along the first line. Then its equation is y = 0. The other two lines necessarily have equations y = a and y = b for some reals a and b. Then you calculate the other quantities involved via a and b and other parameters you have to introduce. At the end you calculate the coordinates of your three points and verify, symbolically, that they lie on the same line.

Indeed. The electric vehicle incentives are very much designed that way. The rich get more money than the poor. The higher your income, the more you get back. I'd have to earn an extra $30K to get the full $7,500 (and switch from high deductible to traditional healthcare/cancel my HSA), whereas someone wealthier buying the same car gets every cent.
that can't be true as rich people are by definition a small minority. why not just give the subsidies directly to the companies

I have programs that depend on pygmentize so I am not sure I will use bat anytime soon when I already have pygmentize and less, or at least not for it having syntax highlighting.
Syntax-Enhanced Self-Attention-Based Semantic Role Labeling
Single slit diffraction and double slit diffraction are very different. This difference is elegantly and simply explained by the wave model. Without it, you'd expect the double slit experiment to create a simple sum of the pattern from each of the slits, but what you get is a completely new pattern that depends on the spacing between the slits, and the wavelength of the thing passing through.
Depends on the textbook, of course. I've personally found that commonly-used university mathematics textbooks for standard courses to be of equal or poorer quality than high school texts.
How long should Apple keep 32 bit support? Apple hasn’t shipped a 32 bit Mac for a little over a decade, warned developers back in the 10.6 - 10.7 era and they cancelled 64 bit Carbon.

Should Apple also still maintain Classic MacOS support? PPC support? 68K support? As far as “no good reason” with as bad as Intel is falling behind ARM - especially Apple’s own ARM designs, it’s widely expected that Apple will move away from Intel to ARM in their consumer laptops. Apple dropped 32 bit support in their ARM chips two or three years ago.

Besides, every bit of code you can get rid of is less of a service area to support, maintain and for security vulnerabilities. The more than half dozen ways of defining a string in Windows has led to security vulnerabilities by itself.

Even MS dropped support for 16 bit apps in 64 bit Windows.
