That is such a nerdy perspective, totally stuck in the filter bubble.

I don’t think that explains the difference at all. I think it’s about convenience. People don’t want to use apps for the diverse things they do on the web all the time. Apps may be convenient if you use them frequently (and then only marginally, especially with improving speeds and more people paying attention to making websites usable on phones), but if you use something not so often?

I try to find an app for things I regularly (daily) use. Some things have excellent apps which far surpass the web experience for me (like Reddit, Linkedin, Inbox, Skype) while others are crap (all HN apps I tried, including the paid ones, Hipchat (what a piece of...), almost all airline apps).

But when the experience of the app surpasses the web, it does so by such a stretch that when I start the web version on my desktop I close it again and take out my iPad. For me a company definitely only takes it's customers serious if they have smooth native apps as well as a smooth responsive web experience.
Those are all apps that actually need more access to the machine's resources. That's not really a comparable to what -most- apps in all of the major app stores do. Most of the apps in the app store are just for media consumption and generally the web version is better than the native app. See Facebook for example.

Media consumption v media creation I think is the distinct line that need to be crossed before a native app makes a whole lot of sense.
All I can say is that I watched both in real time and stand by my opinions of just how severe these various periods were. Note, for example, O'Neil allowing the passage of Reagan's tax rate cuts. Sure, he was about as utterly vicious a class warrior as we've ever seen on the modern political stage (e.g. https://www.nationalreview.com/nrd/articles/336185/good-ol-t...), but he could have totally shut down Reagan's agenda if he was willing to pay the political cost, the House leadership has near absolute control over the agenda, which wasn't true for the Senate in modern times until Harry Reid.

Although you do have a point about how the MSM treats budget conflicts for a Democratic vs. a Republican Congress. One complicating factor is that the Republicans did not control both houses during the period 1955-1993.
Site owners that need to use this shit probably also ignores users need for privacy, like ignoring unsubscribe requests, the right to be removed from their databases, or hiding the fact that they distribute or sell user info.

I'm in my late 20s. I think a lot of these tricks were a result of George Bush II's "No Child Left Behind" testing mandate (2002? around there), where test results directly correlated to the amount of federal funding you'd receive. In response, teachers adopted quick tricks in order to optimize for test performance (i.e. 'teach for the test'). I'd wager these "tricks" are what teachers are forced to use to cater to effectively get the average student to perform optimally on those standardized tests. People just now entering their undergraduate programs, I speculate, will be familiar with these shortcuts.

Math is taught in a wide variety of ways, depending on where you live, what type of schools you're going to (private east-coast Andover/Exeter vs inner-city Chicago), how rich your city is (higher taxes => more money for schools => safer/better environments => fosters a better learning experience & a life at home that values rigorous grasp of academic concepts), etc.

I was one of those lucky guys to grow up in an environment that had a heavy emphasis on academia at the 'publish or perish (then tenure)' level and my school systems emphasized concepts over rote memorization (i.e., a course on geometric proof formulation where you are given a set of axioms from which you must derive all consequential Lemmas, which is basically the opposite of 'heres a few tricks'),

If your class size is 35, and you have even one or two disruptive kids in class I'd imagine even the most dedicated teachers would start 'teaching by the tricks, for the test'.

To answer your question: America is a big place. The difference between most Euro countries is culturally less than the difference between NYC and Harlan, Kentucky.

An interesting corollary of this is (let's choose to ignore ethical implications here -- I believe everyone has the right to free, high quality education, housing, and food), but purely from the POV of workplace-competition-over-jobs, the more schools continue to teach poor analytic skills, the less competent my competitors are.

Given the large pension shortfalls we are routinely seeing, the inevitable federal bailout will result in a federal tax liability. In a society where people routinely move, having ones property taxes collected and distributed at the national level might make sense. Of course, it could never grow very large -- you have to rely on local assessors to properly set basis levels.
At least for most usable apps with ads there is the in-app option to switch them off. I don't mind that for an app that is good ; on the other hand, I would've paid for that app as well in the first place.

If your site will be sending something of value over email, then people will want to use a real address, and you don't need this. On the other hand, if you just want a user ID, then it doesn't matter what they use, and you don't need this, either.

So, if you use this, you're a site who wants a real deliverable address for some reason, but which doesn't offer enough benefit to the user to naturally compel them to share one. Put differently, if you need this, you're precisely the kind of site that shouldn't get my real address.

All that this script means is that I'm going to leave your site unregistered and frustrated, and will mentally bookmark your domain as "those twits who force you to sign in and creepily want an actual address".

I think you won't find animals that use rolling as their primary method. Problems is that for feet, you need a patch of relatively flat surface every footstep. For wheels, you need a continuous stretch, or you need a design that can withstand impacts. Small animals have an advantage there, as gravity isn't as harsh on them as on larger animals.

I agree with the hard-coding being not-too-great-of-an-idea. However, I'm going to argue that a @gmail has a way higher chance of being a legitimate email out of a random sample space than a domain from @tempx.com.

The larger issue here is if someone is entering false information, it's likely because you don't have a good UX and are soliciting information before value is delivered.

With passport.js, it's so easy to implement authentication providers against existing FB/Twitter/LinkedIn accounts, which should suffice for your SaaS 14-day trial. When it expires, they'll enter in legitimate information if they see value added to it.

I understand everyone wants to capture e-mails for drip marketing purposes, but if you have a bunch of people entering fake information because you walled off something critical (Oracle, I'm looking at you and your JRE...), it's not an engineering problem - its a social one.

I think you are right. And I'll add that on smartphones that are in the low- and mid-range segment, mobile version of websites are often way better than mobile apps.

For example on my smartphone (a Wiko Cink Slim), I uninstalled the Twitter and Facebook apps because mobile.twitter.com and m.facebook.com are much quicker and responsive than the Android applications. They also do not request as many permissions, and are more featureful (e.g., Facebook chat works on m.facebook.com while it isn't included in Facebook's app, and rather requires an additional very intrusive shitty app).
Terry’s entire life and sense of reality are twisted in ways you probably can’t even imagine unless you’ve tripped before. You seem to lack the empathy to imagine what it’s like to live as a Schizophrenic. I just ignore the racist bullshit along with the religious nonsense just like I would from someone with turrets syndrome or dementia. By doing so, it frees me to admire the beauty of his mind and work. I’m sorry you can’t.
Yeah, but when you buy a license, you get access to the full source, which you can adapt to your needs. I think that's a much better option than building a similar tool from scratch.
I agree with the premise that it is destructive for students to merely learn tricks in order to pass classes.

However, the existence of tricks is enormously useful once understanding the underlying mechanism of a particular tool is not the focus of a problem at hand. Abstraction is a fundamental human cognitive faculty. For instance, if a student understands why the cross-multiplication 'trick' works, then they should be free to use it as they please, provided they can actually explain why it works if prompted to do so. The notion that there was a 'right' way to do something (like use common denominators) was stifling and frustrating during my school years. If I can explain and justify the trick - then let me use it. On the other hand, being boxed into doing things the instructor-sanctioned way can lead to equally vacuous understanding: "Teacher says find a common denominator so that's what I'll do even though I don't know why".

Additionally, I will argue that all methods for doing computations with fractions are 'tricks' at some level. After all, they are just theorems on the field of quotients of the integers embedded in the reals. One should not be precluded from using a 'trick' because one of these theorems ('common denominator method good - your trick bad') is more familiar to an instructor. Replacing one 'trick' with what is actually just another does not facilitate understanding.

Of course, this is predicated on actually understanding the tool in the first place.

I take an opposite viewpoint from the author(s). Students should be encouraged to develop and use tools. The utility of hiding complexity [0] with tooling is part of the very essence of what it means to be a hacker. It is also very useful in other fields. For example, a physicist solving for the flow of some fluid does not need to think about why a particular fraction trick works. This would draw precious cognitive resources better served elsewhere.

Once a concept is understood, tricks become useful tools. In a field such as building construction, short-cuts are often expensive in the long run because the benefit of making some compromise (e.g. use cheap plaster) is outweighed by its consequences (e.g. need to re-plaster after short amount of time). This mode of thinking does not apply to mathematics.

Tricks are not 'bad' and should not be nixed. They should be embraced and presented as tools of great utility.

Understanding what is and what isn't obvious to other people is a good chunk of what makes the difference between a good teacher and a bad one--possibly the single most important factor. Yet it has nothing to do with what makes a good mathematician.
A national property tax might be "progressive" at the city level. I'm not sure if this is desirable or not, but it might create an incentive for development in other cheaper/value locales.
It's been 472 since humanity realized the Earth moves around a star, 328 years since we knew the equations of gravitation, only 100 since we learned about GR, and only 15 years since we were certain the universe is expanding.

I think we might be excused to take a few more years to nail down the rest of gravitation. There's an embarrassment of riches of data; it just needs assembling into a picture.

Why is accurately representing Terry so offensive to you?

Why is political correctness so important to you?

1. Because hating entire races of people is a bad thing and it's something we ought to consider along with his achievements.

2. Some people would rather not hear/read a bunch of racial slurs so it can be helpful to give others a heads-up if they're thinking about checking out this guy's videos, so they can make their own call.

3. In some ways his unique mindstate is relevant to his work; TempleOS is a monolithic work, created in isolation. His mental illness renders him unwilling/unable to work with others, perhaps contributes to his bizarre racial outbursts, and yet also in many ways makes him able to create TempleOS - something many of us find fascinating.

Please note that nobody here is advocating that Terry shouldn't be allowed to have his say or that threads about TempleOS don't belong on HN.

Personally I really enjoy them and I find TempleOS fascinating.

I wonder if all the critical commenters here feel the same about sites sending a verification e-mail before completing your registration. After all, it serves the same purpose of preventing usage of bogus e-mail addresses.

Linux vs Windows result was that the whole question become pointless, desktop computing was replaced by cloud and mobiles. This will be eventually also fate of FaceBook - we might see no direct FB killer, but something completely different which makes whole class of social networks pointless. Maybe telepathic technology - we could barely guess. Btw, same thing will happen with Google as search engine - generic web search is already less and less relevant, as we do not have "homepages" anymore, relevant stuff is consolidated to few portals which have better direct search. This does not mean that the corporates disappear - if they are well run then they just adopt to new areas.

Do you know what percentage of algorithms have formal proofs? About 0.

I've been in this industry for 20 years now, and I started out saying this, and now I hear this from others. That is obvious. Sometimes you deal with inherently complex problems. I was in the defense industry for a long time, and air-traffic control is a complex problem.

I’ve always felt that theoretical physicists should give more thought to the implication that gravitational waves don’t exist. Just maybe it would require reworking relativity in a way that’s more compatible with quantum mechanics. Sadly, it seems that everyone seems to think the flaw is with the standard model not the other way around.
I worked in a similar field until recently ... a lot of the ICs being used were automotive rated, hence the high temp rating. Also, pressures on the outside of the tool get massive - up to 15,000psi depending on depth.
Native apps can be even worse - they control all behavior to a more powerful degree. The bloat and battery & data drainage is why I install as few mobile apps as possible.
I think that there's a un-elected bureaucracy and then there're elected officials. I don't really have a problem with the elected officials trying to persuade. I don't have a huge problem with them trying to persuade using the bureaucracy as a tool.

Sometimes though it seems like the tool has a mind of it's own. That it either has it's own agenda or doesn't heel to the agenda of the elected officials. All policies aside this seems like a terrible thing - it's a direct path back to having all bureaucrats be political appointees.
Verification emails serve the purpose of ensuring that people don't sign up other people's email addresses.
You'd think a binary pulsar would be ideal for measuring gravitational waves: they're precise clocks swimming in rapidly changing gravitational fields.

Interestingly, binary systems of pulsars are the only source of evidence for gravitational waves. Astronomers use the pulsar timing to detect the slowing of orbital motion due to gravitational wave emission. I wonder if it's possible to detect a 'local gravitational wave background' modulating the pulsar timing on top of the usual modulation from the slowing binary.
But do you find racial slurs acceptable when rappers use them, or when they're used in Hollywood movies, or books like The Adventures of Huckleberry Finn? I guess I don't understand why people selectively find it so offensive.
> being nice all the time, to everybody is for saints/idiots and plenty of social games are zero or negative sum.

Sure, but that's only because the rest of us are being nice frequently enough that your statement is true. If everyone decided to start “gaming” social interactions, i'm not sure we'd be left with a society i would want to live in... Part of the social contract, i think, involves not emphasising what chumps everyone is for following it. For pragmatic reasons.
