> I struggle to even move buttons around (if I fail to update all constraints right, the whole layout collapses)

I would say that accurately describes my experience with CSS. Any selector has the potential to mess up the entire page.

With NSLayoutConstraints, not only does it match my mental model of how layout ought to work, but I know that in a properly-factored layout, constraints can only mess up their local section.

Globals make debugging tough in any context, and I wouldn't blame the language simply for allowing their use.
Floating point math itself is commutative, but it's not associative as it is implemented in current processors so you've already lost associativity from the get-go.
1) It's a race to the bottom. If Germany or France lower their taxes, Ireland will go even lower.

2) It works for Ireland to have low taxes, because they are a small country collecting the tax for the entire profits in the EU. Even if their tax rate is low, they still get a sizable benefit. This can't work for the big countries.

Interesting how nuance is important: Obama's big data was public or obtained legally to supplement his campaign's ground game or TV buying. While Trump's big data was based on stolen data and used to discourage Democrats from voting.
This is news to me. Will it likely affect Nvidia in any significant way?

From p.18 of the report:

"What is new in the hardware driver is that Chinese tech giants and unicorn startups are competitive with some
of the world’s leading companies in designing AI chips. For instance, Chinese company Cambricon, a statebacked
startup valued at $1 billion, has developed chips that are six times faster than the standard GPUs for deep
learning applications and use a fraction of the power consumption.65 Moreover, equipped with a new “neural
processing unit,” Huawei has arguably overtaken Apple in mobile AI chips.66"
There are theoretical models of random-access machines with fixed-size caches, on which data structures like B-trees and others can be (and are) analysed for asymptotic performance. It's usually not taught until late undergrad or graduate level though.

(You may have heard the terms "cache aware" and "cache oblivious" used to describe algorithms. These terms come out of theoretical CS, describing algorithms with good performance on these "RAM with cache" machines when the cache size is known or unknown ahead of time, respectively.)
Having lived in both, I have found that informal challenges to power structures in cities are much more merciless. Ask any (nonconforming) conservative in nearly any large city, especially on either coast. Or in any online forum dominated by people from such places, for that matter.

On the other hand, people in the small towns and small cities that I have lived in are much more tolerant of the nonconforming aspects of my personal views and lifestyle -- which, ironically, they tend to view as 'liberal,' even though objectively I am much more 'conservative' than they are in most respects.

This new world driven by the constant emphasis on differences rather than on commonalities is exhausting, frankly.
The code is ideally a "this is the code that fixes the problem" and its done. Once there's an answer, you don't often get a dozen more answers with slightly different code.

Library recommendations however - everyone has their favorite. Someone recommends Spring. Someone else recommends Play. Someone else recommends Stripes (and then has a dozen comments explaining the different between Stripes and Stripe). Someone else has Struts (and then gets a dozen comments about the version they're recommending being out of date and lead to the equifax breech). JSF, Jspx, JHipster, Grails, GWT, ... it goes on and on.

And now that there are a score of answers, some new user sees the post, doesn't read everything and recommends a new version of Spring. Or points to a different site for Struts.

The curation of such a question takes far more work than the question is worth. Look at how much effort the C++ community puts into maintaining the C++ book list. Spending that much effort on each recommendation question is far too much moderation time across the community.

On the other hand... go to a site that is designed with exactly that goal in mind. https://www.slant.co/topics/40/~best-java-web-frameworks does it much better than Stack Overflow can.
Windows forms is based on decides old WinApi. There's some support for styling there, e.g. owner drawn items, custom painted controls, but using it correctly is tricky as hell.

WPF is based on Direct3D 9, and is easily stylable. I consider it is the gold standard. But it is Windows only. There are cross platform alternatives, xamarin, avalonia, but I don't have hands on experience with them.
Perhaps your view is not shared as widely?

It was intended to be a contrast of what downvoting is vs should be.

"That site you try to contribute to is horrible and the problem is the people" - well ouch. Retaliate hurt with hurt. Or comment with downvote.

Do read my original post. My problem is people who don't actually contribute but nitpick on how the questions are worded.

But I do both.

I pick on details until I feel the question is sufficiently clear and scoped that I can answer it, and then I try to answer it. Sometimes it never gets answered so my comments are left as just nitpicks and sometimes it's answered by somebody cleverer or with different experiences before I can understand it and it looks like I nitpicked while someone else answered and I should have answered instead or shut up.

But unless you only want the best people answering you get whoever is about and willing to engage.

And aren't we then back to the open source model - it's shitty but it's free, who are "you" to expect or demand better?
A fun filter i used a bit back when i was a scientist was the rolling ball filter:

https://imagej.net/Rolling_Ball_Background_Subtraction

It took me a while to realise that this is just a cousin of convolution: in a convolution, as you sweep the kernel over the image, combine pairs of pixels and kernel elements with multiplication, then summarise the results with addition, whereas with a rolling ball, you combine the pixels and kernel elements with subtraction, and summarise the results with the maximum. The kernel used is the 'ball', but there's no real reason it has to be based on a sphere in any way.

I wonder what other image processing operators could be built in that framework?

The helicopter people on this forum seem to conclude that the fall speed of heavier
helicopters is slower:

> The most unappreciated aspect of the helicopters' impact, though, is the noise. They ruin the possibility for enjoyment of the waterfront for a several block radius around every pier that they use.

Agreed. I wish helicopters were banned or only allowed on high rise helipads. They are so loud that it hurts your ears if they are anywhere near your vicinity. Noise pollution should be a consideration as any form of pollution. Also, if helicopters fly by your building, you can feel it. It actually vibrates the building. It really gets on your nerves and affects your quality of life.

Helicopters and horse buggies in central park are two things we don't need in nyc.
Fair. It seemed worth mentioning the larger context, and this seemed a plausible place.

Doing VR/AR, I've been struck by how not good the community is at attributing design constraints to cause. Constraints are simply echoed ("90 fps or sick!"), without attention to their context and scope of validity. Being unable to clearly see one's design space, impoverishes imagination, planning, and outcomes.

Many of the comments on this page reminded me of that. And parts of the OP. We can usefully discuss whether the apocryphal shoemaker had better today prohibit his oft-crippled children from dancing, or going outside, or walking, but it's worth bearing in mind that the root cause of the cripplings is the ongoing failure to provide shoes. And all the rusty bent nails we've left on the floor.
I've always thought that one of the reasons SO was so successful is that they were an early adopter of easy to use markdown for code snippets, with a fairly snappy, simple UI.

Compare this with the alternatives around the same time, like Google Groups/Discussions or phpBB, which are still painful to look at to this day, IMHO. Is there anyone who wince when have to scroll through nested threads, and unformatted raw text in code to understand something?

I agree. Personal experience is that even moderate drinking causes poorer sleep and mental performance but can only be observed after you have been clean of alcohol for months. After you are in the habit of drinking multiple times per week you can not compare your state to the baseline of non drinking. I ran into this by accident when training for a race and did not believe it when people told me.
You can hardly talk about cities booming, while ignoring the obvious and dramatic other examples.

The big epicenters of intense poverty and murder are all hyper concentrated in the cities, not in towns or rural areas. Baltimore has a murder rate 20-25 times that of a typical US town.

Or: LA's massive homeless encampments. Chicago. Detroit. etc.

West Virginia is really poor right? Considered one of the poorest states in the US, and has among the highest unemployment rates. You won't see homelessness, murder and extreme poverty in the towns around Morgantown like you do in the aforementioned cities.

The entire state of West Virginia has 1/5th as many murders as Baltimore, with three times the population.
I wonder if Forth is still used today for some applications of if anyone has stumbled over some production Forth code lately.

For me, Forth is a language in which you can easily shoot yourself in the foot. One element more or less on the stack and you run into strange problems ten functions later in your code.
But what I especially like is the enhanced naming of "words". You can choose "variable" or "function" names such as "a->b" instead of "a2b()" or "a_to_b()". Or "@X" for "GetX()" and "!X" for "PutX()".

I believe that lead in petrol / gasoline still exists as there are not one but two effects from lead.

One is that lead helps promoting burning of the gasoline versus explosion or knocking.

Two is that lead is a great lubricant for the valve surfaces, preventing them eroding, leaking or sticking as they open / close. Eroding causes the engine to lose compression and efficiency, and sticking (as I have experienced first-hand) can cause a major engine failure by breaking the mechanism that opens/closes the valve.
> meaning they have a strong incentive to increase usage of digital services and a disincentive to put in place regulatory measures that would decrease adoption and harm growth.

They have an incentive to increase revenue; you can do this by increasing the rate much more easily than promoting growth. The only thing working against this outcome is EU institutional inertia.

I strongly disagree with your notion.

The results of creativity spreading to the economy can be hampered by the government. But I strongly disagree that creativity and innovation can't flourish under authoritative regime.

Educational system does not create or remove creativity, it's just a common myth. The reason why Chinese students look so mediocre is because they value science and engineering so much. It's seen as a path to good live. The creative people are still there, but there is more mediocrity because there are so many of them.

China: 4.7 million STEM graduates per year = 34 per ten thousand.

US: 0.56 million STEM graduates per year = 17 per ten thousand.

Chinese have adopted market mechanism and Chinese companies compete on global free markets. Government is just coordinating and supporting the industry just like DARPA is doing in the US.

The engineers way of thinking about Fitt's Law is as a human control system. We motion control our hands by using feedback (visual, tactile, proprioceptive). The servo time response to a step function (new location to click) of that feedback loop depends on the required accuracy and allowed overshoot. The larger the target, the higher a velocity/acceleration you can use to hit it without missing. You learn very quickly that large objects (like edge of screen) allow much more gross movements than single pixel target... and the farther you have to go the larger the time at a given tracking velocity.

What is at least as interesting is the cognitive load of tracking/pointing, clicking/chording . Mental load and apparent time appear to be the reason why typing can be slower than a menu system, but it feels faster. Similarly, people will report a feeling like a trackpoint (IBM keyboard nipple) takes longer than a mouse even when they're actually faster in hitting targets. Presumably, this is because they have to track the cursor to know velocity and position, while a mouse or touchpad uses your body's knowledge of hand position/velocity that is missing from a force based input.

What you're used to feels right in any case.
Oh dear. 2 hours in and all the comments appear to me to be the kinds of politically trolling that we typically try to avoid on hacker news.

I honestly don’t see how this works, are you saying the banks are taking a massive loss on this venture? If so, wouldn’t the banks rationally avoid making loans to companies acquired by vultures, since they would always lose money to them? Who are the individuals taking a massive loss?

I’m asking basically why anyone would loan money to Toys R Us after it was acquired by corporate raiders.

This is why when I got my first motorcycle my buddy told me "lets find a beater on craigslist thats been in a crash".

I paid about $2k for it, and that yamaha had seen a hell of a dump at 50mph and had scratches that looked like a banshee had its way with the left side because it insulted her mothers size or whatever.

But damn if he wasn't right that when I inevitably had it fall over whle practicing in the parking lot that I didn't care much. Plus after riding that (not quite a) beater I was much better prepared for stuff with more zoom to it.

I think buying cheap/refurb/broken and learning from that is definitely the way to go when starting/learning. You learn how to appreciate the good stuff later on.

Just like how now I can pretty much use unix to a large degree after using them for ~20ish years, I tend to stick to osx+nix to get me up to speed. I keep my configurations portable to open/freebsd and linux as well on the off chance I need to move around, but other than that I tend to not be too committed to what I'm running.
Frankly you've essentially hit on the main issue there - the problem with SO in its current form is "bad questions". But people who are asking questions are typically not people who understand how SO works and don't know how to ask "good questions".

The other day I was having a weird problem and after much googling I found this:

https://stackoverflow.com/questions/49091270/why-is-socket-i...

This was sitting at -1 because the asker didn't know how to "craft" his/her question. Its a legitimate problem/bug in NodeJS LTS itself. It still hasn't been touched after I attempted to answer it =/
Because it's easier. When I started soldering, the lead-free stuff was finnicky but I had nearly no problems with leaded solder.

Regardless, you should have good ventilation when soldering. A small fan to suck smoke away, maybe even a mask, and take care to clean your hands and the area like you would any other harmful material (e.g. oil).
Was wondering if guitar or culinary arts would show up. I read in Bourdain's "Kitchen Confidential" that Chefs bring their own knives. Hence an attachment to the tool and appreciation of quality. Guitars are similar, in that a mint condition guitar is nice to look at but kind of scary to play. The highest selling instruments have been famous for who played them, when, and where, not the brand or how close to new they might be. It's funny how artisans who base their livelihood on tools relate to them versus the drop-in tourist who starts cheap and gives up easy.

That is absolutely false in my experience.

In terms of your question on education, I have only experienced Canadian education but I have never thought of it producing "factory drones" , exactly the opposite. Some of the most creative thinking I have seen has been in the classroom, with professors/teachers asking us to point out their flaws, or think of better answers than they presented.
You wouldn't be seen as a "perpetual foreigner" (gaijin) like that, and American culture is much more lenient on foreigners carrying along their old customs compared to in Japan. Overall I'd expect an easier time, particularly in that it's always achievable to be seen as American (more in some areas than others, especially SV, not to say the US doesn't have any problems with discrimination), but in Japan a foreigner or even foreign-looking native is never truly accepted as Japanese, as pointed out here: https://news.ycombinator.com/item?id=16612178
