Adhering to Mac UX conventions is harder with Electron, because a lot of little things that apps get "for free" with the native toolkit have to be explicitly included or even re-implemented under Electron. Visual Studio Code, for instance, has explicit support written in it to be able to use macOS Services; earlier versions of Code just didn't work with them. If its UI was written in Cocoa, this would have just come along for the ride. And at least off the top of my head, I can't think of a single Electron-based app that I use which fully behaves like a Mac app in other subtle ways; for instance, Slack, Telegram, Atom, and Code all do their own weird things to control their settings rather than bring up a modeless preference window the way every native Mac app does. Maybe it's modal! Maybe it's modeless! Maybe it's a JSON file! Who the hell knows. Does it bring up any internal windows that look like the native OS's windows? Does it support all the common text editing keystrokes that Macs have supported since 1984? Does it even integrate with the system font selection system? [shrug emoji]

I presume this is true for other platforms/toolkits as well, and it's a tradeoff that doesn't get talked about as often as it probably should be. I'm not using a Mac because I woke up one day fifteen years ago and said, "You know, I'd love to pay a lot more for hardware than I probably should just so I can get minimalist industrial design, too few ports, and dubious keyboards." I use them because I like Mac UX conventions. I've talked to many people who actively prefer Windows UX conventions, or KDE or Gnome. I am not thrilled with the notion of a world where everything is a pseudo-native PWA.
The abstract machine is designed to be relatively easy and efficient to implement, but specific features such as vectorization are not part of the standard. Remember, C++ runs on machines that don’t support any “advanced” features, so there is a limit to what can be required in the standard.

I'm curious what the answer to the title is but "aluminum metalized polyethylene terephthalate" doesn't exactly help me. Aluminium, okay, but what is the rest? The article goes on and on and on, rambling about how everyone likes it just like we once hunted for honey, what company it originated at, what kind of word it even is... thousands of words for a couple of interesting bits of information. This either needs a summary or some more concise writing.
High speed rail is a non-starter in the US, except for in certain regions.

It's 2000 miles from Chicago to LA. Optimistically, if you had a train that averaged 200 miles an hour, it would still take 10 hours. That's just not competitive.
Wow, just wow!

I've often felt that we (humanity) have pushed the boundaries of our knowledge right to some really hard lines to cross: relativity won't allow interstellar travel anytime soon, we are making progress in "soft AI" but "hard AI" is still insurmountable, even fusion seems as far as it's always been. Further "real" progress seems sometimes nearly impossible, or very arduous and slow at best.

Then this guy shows up, cuts a frog's leg, shines some weird lights on the wound... and the frog regenerates it! (frogs do not normally regenerate legs). This has been really astonishing to me. I hope this whole research area lives up to my excitement after listening to that talk, because really awesome things may come out of it.

I highly recommend this talk to literally anybody who has scientific curiosity en general!

It’s only a preview feature in 12, so you need to give a command line switch to java for it to be enabled.

It’s also the first part of a much larger feature adding pattern matching to the Java language. Getting all the ducks in a row for this sort of thing is tricky because it touches so many other ares, but switch expressions can be delivered on their own quite nicely.

Adding patterns means looking at variable scopes (where is a variable bound in a pattern in scope?), record classes (because destructuring patterns should not be implemented by hand everywhere), and even constants and raw string literals (because being able to switch on regexps would be nice, and you need a good way to write that).
Currently, Toronto-Montreal isn't even bring considered for high speed rail. If anything, the Toronto-London corridor is what's being evaluated.

Thank you for your time there. I end up on Quora quite a bit, at least when searching camparison based queries and the really long answers that cover a subject in (sometimes extreme) depth have been fantastic to read. I have read some answers that outperform StackOverflow, StackExchange, and UnixExchange in terms of quality and detail. I love reading answers from people that have intimate knowledge about a subject and don’t just post sourced images or links to documentation that the question asker didn’t understand the first time they read it (which is usually stated up front).

Granted, most of these posts are early 2017 and earlier.
Because people only ever fly cross country. Also ignore the carbon footprint. Also ignore the time to and from airports.
Canada's size, terrain, and population density make it a special case. Ottawa-toronto might work, but vancouver-calgary would be insanely expensive if even possible. Linking across the country ... we might as well not bother charging for tickets and just call it a government project never intended to break even.

And in the north, spaceX rockets might be cheaper.
So make it regional. There’s no high speed rail from Paris to Moscow either.

Make it an overnight train with a real bed and the train sounds more appealing to me. Do a days work in Chicago, go to sleep, wake up, do a days work in LA.

I mean, the thing about narcissism is that those with overly narcissistic tendencies are not exactly hard to spot. There are only so many ways for a person to be consistently self-aggrandizing, entitled, envious of others' success, craving for universal admiration even more so than power, etc. And yes, "not letting those people be president, maybe?" is a good idea. It's also really hard - the primary process especially, even more so than the general election, rewards people who are committed to rallying the party base and inspiring universal admiration from others, by any means necessary. We've seen so many examples of that.
String substitution and raw string literals aren’t really that closely connected. I’d also suggest that if string substitution becomes nice it will get used far more, so it needs to be implemented in a way that constant folds things nicely. So if I had to guess it might get looked at after the work being done on constants.

I'm pro-transit (I vote for it whenever it is on the ballot, and take it frequently). I'm also skeptical of Musk at times, especially the promises about "full self driving" in Teslas.

That said, I find the urbanist/transitphile community's response to Musk's tunnel ambitions off-putting. Most of the criticisms I've seen seem to presume that a person who has revolutionized space travel and electric cars can't perform basic math about passenger throughput. Excuse me if I have more faith in Musk than the naysayers.

> Yes but they could have provided both a single-container-parameter version and a two-iterator-parameter version of all those functions like sort and transform.

For my own libraries I'd skip the iterator accepting version. Implementing one range type is way easier / less prone to oversights and other mistakes than double implementing every algorithm. Or more than double implementing, if you need perfect forwarding for non-copyable functors without std::forward pre-C++11. Even though all they do is forward.

SC++L doesn't get much choice since they started with iterators only, but even there, I'm not sure how much time skipping std::range saves you. You can't even take a plain C style array without either a range type, free-form std::begin/std::end, or the iterator variant.

Pretty much this. As a quant / data scientist, I quite often have notebooks just hanging there for weeks with a few hundred GB of ready-to-use data preloaded and preprocessed in the kernel which makes the experimenting with it incredibly ergonomic.

Being able to quickly check the output while iterating on a an algorithm, or visualise intermediate results is irreplaceable.

You're starting with the concept of "Russian SSR" to mean "Russia" and going from there, and this line of reasoning makes sense. But really, "Russian SSR" was the novel concept. Before the USSR, "Russia" meant the "Russian Empire", which comprised of basically the same area as the USSR. So during the time of the USSR, "Russian SSR" had no meaning (to the West), it's only significant now in hindsight after the breakup. To summarize this perspective I'd view it like this: The "Russian Empire" i.e. "Russia", was renamed "USSR" and internally they drew lines to make states, for which "Russia Core" for lack of a better name was simply called "Russian SSR".
Wendover had a good video about China's rail network a while ago. [1]

Major points are:

1. China is willing to build loves that aren't self sustainable - whereas the USA isn't (and the US doesn't factor in the social benefits)

2. China's airspace is mostly military - leading to only small flight corridors and therefore significant delays for flights - making trains more reliable

3. China is willing to make train lines that make no sense beyond connecting areas that are not as friendly to the government to areas that are in the hope of increasing government support in those areas

I'd take a 10 hour train trip from Chicago to LA in a heartbeat.

Security lines are shorter, and the beginning and end of a train trip both happen at a literal train station, so it's usually easier to get into and out of the city center.
This made sense in theory, but how could aluminum go from being not on the film to being on the film without at least some Scotch tape? “They evaporate aluminum and deposit it on it,” said Mr. Shetty. This made sense in theory, but how could aluminum be evaporated? “It’s a very, very thin layer. They put it in a vacuum chamber, then evaporate the aluminum,” said Mr. Shetty. “With heat,” his son added. “What are they evaporating out of it?” I asked. “Aluminum,” said Mr. Shetty. I have no idea how humans figured out how to do that, or why it occurred to them to even try, but it sounds expensive.

What's worse, the lack of understanding of high school science among journalists (Boyle's law and elements changing state are very basic chemistry) or the the lack of communication skills among scientists?

I quit Quora after they deleted my account by mistake - in the process of merging my two accounts with different emails, they managed to delete both - and then said "sorry, we screwed up, but unfortunately we can't undo it".

Chris Roberts repeatedly over promised, feature creeped out of money and was saved by big companys like microsoft who bought his title and had other managers step in and do the final cut.

Yes, i know, i know - the big evil companys are always limiting the creative freedom of the "artists", but when the artists want to party like there is no tomorrow, somebody has to put a foot down.

The foot down guy definitely was never Chris. And yes, he was for quite a while out of the industry, because of the scope creep.

I liked the old guard of game-designers, very much. Peter Molyneux always overpromised, and still he and his other bullfroggers delivered and they did great leaps. Something that is missing today. So i want this whole thing to succeed.

But somebody has to be the bad guy here. I want the reassuring words of a bad guy saying to me that this idea or that feature will not make it, and that this is final. And that there will be no new ideas, no new features. And it stays that way. Just once.

Damaging an economy pressures a government whether or not there is any kind of pressure from the citizenry. Governments need economies to run, especially ones depending on the military to “keep peace”.

It takes a special kind of naïveté to think governments run in a vacuum independent of the economy.

Traffic congestion is a pretty big issue for intercity too in some regions. Dallas-Houston is a mere 240 miles but often takes 5 hours to drive. Even in "light" traffic, 4 or so is common.

You can do a lot better than that with even decently upgraded "legacy" rail, never mind a Shinkansen/TGV type system. For example, London-Manchester is 210 miles, and trains take only 2 hours.
Thanks to subsidized exploration, and a federal highway tax that is 30 years behind, and no accounting for negative externalities.
> Article says they are using an "older method" of gene editing. Well no wonder then, we know that older gene editing methods have a lot of off target effects, crispr cas9 using base modification (instead of deleting whole DNA stretches by splicing) is very safe. This is a FUD article.

Base editors are a very new (first published in the last two years) and have a whole new class of off-target effects compared to the ‘standard’ Crispr-Cas9 approach, namely editing multiple bases in the targeted regions.

I’m not sure why you would say that’s base editing is inherently superior to homologous recombination at the point in time.
I was wondering about that too: the safety considering how secretive manufacturers were.

Intuitively, I'd think the particles are just too large to be a considerable risk. The photo of the man wearing a mask is because they're around it all day every day (+ OSHA I'm sure), but I'm sure people have though the same thing about asbestos or pink fibreglass insulation.

> Because as I understand it, the US was largely aloof until Germany started pursuing atomic weapons ...

No. The USA public was isolationist until the bombing of Pearl Harbor. Germany stupidly declared war after Pearl Harbor in sympathy with Japan.

The key things to understand about WW2 are:

1) Germany and Japan declared war on a country they couldn't invade because of geography.

In other words, the USA did not have enough deterrence at the time to prevent WW2. [paraphrasing Victor David Hanson]

The B-29 was the ultimate weapon in WW2, not the atomic bomb (which was dropped from a B-29.) So much so that Russia spent vast resources after WW2 copying it down to the last rivet.

2) The USA was already the "arsenal of democracy" a year before Pearl Harbor. Historians regard Pearl Harbor as more of a trap than a victory for the Japanese, which would have required both sinking all of America's carriers plus a successful land invasion of Oahu to end well.

3) All sides thought that bombing the enemy's cities would break their will to fight. As any chess player knows, people will fight to the bitter end with very few exceptions.

why don't you use your real account to make this comment?
The most obvious difference for most people is to how readable text is while it is moving, and how fast it can move while still being readable. For touch interfaces, this is important, as people do read while pushing things around. In essence, anything above a pixel per frame is not very readable. So at 30fps, text is only readable when moving at less than 30 pixels per second (60 for hi-DPI). At 120fps, you can move everything four times faster and still have it look sharp.

You could expand your knowledge greatly by visiting blur busters [1]. It is trivial for humans and cameras to see the difference between 60Hz and 120Hz motion [2], especially when tracking motion. When we were all on CRTs, the difference was much less noticeable, give or take flicker sensitivity, because they display things in pulses. Most modern displays will hold the image until it changes, which any tracking visual system (eyes or camera) will see as smearing. You can see images of this at blur busters.

A lot of often-cited sufficient-for-everything frame rates are incorrect. 24fps is claimed to be sufficient for motion for cinemas, but it only works with heavy motion blur and a lack of fast camera sweeps. 30fps is claimed to be sufficient for games, but it impacts reaction times, input lag and blur in motion. 60fps is claimed to be sufficient for games, next, but it stopped being so when we stopped using CRTs (visit blur busters for more detail). We're now at 120fps for many things and it's almost good enough.

As it happens, tunnels in cities are not some hitherto unheard of great invention. They form a fairly well known and efficient means of mass transportation systems across the world.
If you have, have access to, are able, or want to drive a car, then at best it's reasonable option for places outside of denser areas, albeit far more expensive than the cost of gas. While cars are certainly good in some ways at getting people around to places that don't make sense to service with more significant options, they shouldn't be considered first when thinking about new development imo.
A few years ago I thought Quora was the biggest threat to Google. There were many questions I would go straight to Quora to find answers. I was wrong.
At some level of abstraction all jobs can be made to look similar. It's just not particularly useful to abstract to that degree.

I think if you look in the communities formed by any groups of people sharing professions, you'll find a similar magnification of the importance and uniqueness of that profession: humans generally have a tendency to find the stuff they spend the most time around more significant, and often forget that the significance-difference is in perception only.

That said, because of software's generality (in terms of the number of domains it's applicable to), it is relatively unique.
Please don't post unsubstantive flamebait to HN.

Who is suggesting building high speed rail from Chicago to LA? Why would you pick that particular example? It takes even longer to drive, and yet we have built multiple highway routes that connect LA and Chicago.

Instead of picking dumb examples to discredit the idea, how about looking at obviously good places: The entire East coast from Boston to Miami would be a good corridor to build in. Or start in Chicago, Dallas, Atlanta, and build links to cities between 200 and 500 miles away, where taking a high-speed train would be faster than either driving or flying, and extend from there. Eventually you will have a network that can take you from Chicago to LA, even if that's not the sweet spot for the type of transport. And honestly, a 10 hour train ride will take only 3-4 hours longer than the equivalent flight, once you factor in the huge overhead of time involved in flying.
Is there a solution to the last mile problem? It's every difficult to get to the final destination in sprawled suburban cities even if there's a direct center-center high speed rail line.
Brit by birth, and I've never visited France, so take this with a grain of salt, but:

I've worked with many Japanese, German and British engineers who have worked with French engineers (in France, often as "ex pats"), and these guys never complained about France's 35 hour work week. They did, however, complain about the (this is my summary, from memory) excessive smoking breaks, longer lunches, casual attitude towards work, and (yes, sorry for the stereotype) a good amount of lost time talking about women in the office they'd like to bang.

I don't know. The 2 French engineers I've worked with have been fine, but that was on U.K. soil... maybe on the home field it's different?

My wife, who's American but both parents are French, says that the French generally have an inferiority complex but over-compensate by shit-talking other European countries and the U.S. I don't think I've experienced this personally, although I'm in tech and she's not, so maybe in her world that is more common (or maybe she's wrong? dunno)
