The classroom should be inverted. Each kid should get an ipad or some other tablet, with lessons delivered at home from a marketplace of "best courses" that the schools purchase. Every school day the school could have quizzes to tedt whether the student learned the previous day. If they missed some topics or nuances, they'd get it fixed later that day in smaller classes with more individual attention. If they got everything they can just go home and enjoy the day.

The motivation for kids to learn would be that they won't have to be stuck in school all day (and be accused of having ADD) and they won't miss out playing basketball wrh their friends if they learn everything the night before. It also makes them practice autonomy, self-direction and time management, and lessons by a really good teacher can be delivered to hundreds of thousands of kids instead of 30 -- with multimedia. In addition, kids would be able to paude it, grab lunch with friends, study with friends, etc. And yet they'd still practice being accountable but on a day-by-day basis so the price of "failure" is low.

School should be for social collaboration, remedial help, and practicing. That's where the tutors should be, not at home. Home should be a place of comfort and learning. The internet contains so much information, and by integrating lessons with tablet computers, kids get to develop modern habits of researching stuff online. They might even learn to manage the ADD that comes with being on a million sites at once. If they get restless they can go play basketball or explore and do something physical outside.

Such a school will not happen, sadly, because the goal of schools is to act as a daycare center to keep kids occupied most of the day -- while both parents work. This is what "a good economy" looks like?

This is the kind of school I'd like to send my kids to. Sadly the closest approximation right now is homescholing.
Or, imagine that you didn't like the dominant views among the 50-60 year olds in power when you were in your twenties, and you offered up the idea that we should just withold medical treatment from people over 30 so that we could increase the speed of social progress.

On a similar note, I wonder how this sort of ailment could effect an alcoholic trying to kick the habit. I would think that the victim would figure out something is wrong, but it is hard to say if this could be mistaken by the victim as some sort of strange withdrawal.
None of these seem impossible to overcome. The current proposed HSR is targeted at $60-100 billion, the estimate for Hyperloop was $9 billion. I find it hard to believe that Elon Musk who sent a rocket to an orbiting space station would be off in his calculations by the 550%-1000% needed reach the price of HSR. So I think we should be impressed by the results of this study and get on with more studies to address the additional concerns tptacek posted.

Edit: I'm not trying to rebut or argue about any of the challenges. I'm just saying I find it highly unlikely any of them are 50+ billion dollar problems.
Oakland has BART access, what other last-mile infrastructure are you referring to?

WRT destructive disruptions, I believe there was a section dealing with sudden tube repressurization. If the failure mode is effective, it seems like an attack would be less destructive than one on a train, due to the smaller pod size.

If CapEx is much lower, and energy cost is lower, the ticket price should be lower, unless the maintenance cost is much higher (it may be due to exotic requirements, but it's not fair to say that what he's describing bears no relation to actual cost structure - it's just not complete).

No idea about the routing/tunneling estimates. Were his per-mile tunnel cost estimates much lower than normal?

The motion sickness complaint seems like it would have legs, since there won't be any view of the horizon - your eyes will be reporting a static environment outside your body, and your inner ear will be doing very much the opposite. Then again, planes experience turbulence and mild G forces and have the same characteristic for most passengers of not seeing the horizon. Maybe motion sickness was a much larger problem in the past, based on the presence of barf bags at every seat.
Wow, I... I don't think I can beat that.
"Everything Else Should Respond in Under 100ms. That number is the mental barrier after which things feel slow. Anything under 100ms feels essentially instantaneous to the user."

Not really, no. Anything under about 25-50 will feel instantaneous. Between 50-100 you're looking at something that doesn't consciously register as 'slow', yet feels vaguely sluggish - especially when it comes to responding to taps on a screen.

Native apps[1] typically respond to taps in < 20 ms and gestures in < 75 if not sooner. If your web app does not respond very nearly as fast, it will feel slow to your users.[2]

The good news is that so many html5 apps fail at this, 100 ms is enough to make your web app look good in comparison -- just not in comparison to a native app.

In one of the other boroughs or the surrounding area, however, you can find stuff for a good bit cheaper. Hoboken avoids city taxes and is a 10 minute subway ride to Wall Street. You have to go into war zone ghetto or out to a much longer commute to find something more affordable in SF. The job market for tech in NYC is going to be of a more boring variety on average, but with comparable salaries and I would guess increased stability and benefits. Definitely different strokes for different folks, so not a 1-to-1 by any means, but could be a reasonable option for many people.
You're not seeing the big picture. Touch ID isn't just another gimmicky feature, it's something Apple spend a lot of money on. They acquired the company that made the technology, and improved it in a way only Apple could.

Today it's a method to unlock your device, but there is no way that this is all Apple wants it to do. The possibilities are endless. Imagine not having to put your password into another website, instead you just touch the home button. Making a purchase on iTunes? Use the scanner instead of the password, etc.

But that's not all. This could easily be used in a retail environment, where a prompt on your screen shows up and says "Buy foobar for $5.99?". Touch ID does the rest.
Genuinely curious, what signal do you think it sends? I typically put a lot thought into my physical stuff, but I do not have any connotation, positive or negative, regarding fountain pen usage. If I saw a person using a fountain pen, I would probably think, "That person must like pens. Cool." and that would be about the extent of it.
Nonetheless, the AAUP document seems to show that even at US public doctoral and research universities, in 2005 non-tenure-track employees made up about a quarter of the full-time faculty and about 40% of all faculty if you include the part-timers (p. 18). There's also the issue of graduate students who teach or do research work. The numbers apparently included teaching grad. students, but only those which had been self-reported by their institutions as "employees" rather than recipients of valuable teaching/research experience (p. 10): it's not hard to imagine some under-reporting there.
I am not a lawyer.

Kernel modules don't just access the public API of Linux and are fairly tightly bound to the Kernel. It seems to be the common understanding that they generally do constitute derived works. Certainly shipping them with a kernel is likely to be considered as such.

Having said that see my other comment which I think explains how the GPL isn't viral and also that provided you don't distribute the derived work you are not obligated to distribute the source.
The general opinion is that kernel modules integrate sufficiently tightly that the GPL applies to them, but it is something that has been debated quite a bit, and will probably not be settled until there is a court case that rules on it.

Jira has a kanban feature now (Greenhopper, I think?). I have seriously considered it, although I am fearful of the ability for PMs and clients to use Jira's bazillion other features to make my workflow process hell. I do enjoy Trello's forced fluidity, and cannot wait to port my last few clients off redmine (love the project, kanban fits my flow 1000x better).

Musk's plan runs from Hayward to Sylmar. Both are up to 45 minutes from the HSR endpoints in traffic.

Musk's plan specifically calls for TSA-style security.

Your third point is nonresponsive to the argument. The ticket cost will reflect opex, but Musk's plan doesn't include it.

Yes, his per-mile tunnel cost estimates were extremely low.

Airplanes occasionally experience motion-sickness-inducing G's. Hyperloop pods will every trip. You'd at least want to know if the design is a vomit comet before you sank billions into it, would be the right point to make here.
"Because Elon Musk" is not a real rebuttal to any argument.

A somewhat cynical but I think on-the-money assessment of the Hyperloop is that it isn't at all a real proposal, but rather a sleight of hand to reduce buy-in to the CA HSR plan, which Musk opposes. That being the case, investing money in further studies seems like a dumb plan. Extraordinary claims require extraordinary evidence, and there are extraordinary claims in Musk's proposal with no evidence backing them up, so the onus is probably on him.
Sure. The most obvious one is that you can't filter by user (or at least it wasn't readily apparent that you could).

I also think the keyboard shortcuts on Asana are faster and more intuitive. Don't get me wrong - I love Trello's layout and Kanban - but it feels very light in comparison to Asana (which some probably consider a positive).

As a companion to the OP's animation section, this year's I/O had a really good Chrome performance talk[1].

Tripit has saved me so much time (and helped my marriage too) by solving this problem. I just started using it this summer when I was doing a lot of international travel.

Now, I just forward the email to tripit and I have an item in my calendar (that is shared with my wife) that has just the relevant info (flight time, number, conf #, etc) so I can see it any time and so can she.

No more looking at those awful emails (which I just archive as soon as I forward it).
I disagree. I hear your complaint from many people, but I spend enough time talking to managers to understand what they mean, and I actually think there's content there.

I really dislike rendering active buttons as pure text. Moving away from skeumorphism does not mean removing every visual cue that differentiates active from inactive items. All the more so on mobile devices where "hover" cues are not accessible. Google is also guilty of this.
"... Mercedes-Benz announced Monday that it had successfully driven an autonomous S-Class sedan 62 miles on German city streets."

Well, shit, that quote right there plus your hostile attitude sure have me impressed. 62 whole miles! They're clearly on the doorstep of releasing a production autonomous car, as you were trying to imply over at <https://news.ycombinator.com/item?id=6408590>.

Meanwhile, that other company's car has made the trip from San Francisco to Los Angeles (at least 380 miles, in case you didn't know):

Yeah man! Sign up for our tournaments and leagues! It's still going strong and actually seems to be growing since the advent of newnet, a modern netcode that smooths out gameplay a ton and lets people from all over the world play together.
Endurance in top flight racing is a given. Races are well with in the endurance of the cars.

Dr. Ferdinand Porsche is popularly reported to have said "The perfect race car should fall apart the second it crosses the finish line."

Point is, there is always a trade-off between speed and reliability. If you get to the finish line well within the bounds of your reliability every time, you are sacrificing speed.

But it is less of an issue if the cars are all almost identical.
> Admission rates for colleges have been dropping across the board, for top tier schools even more sharply

I do not see how this could be happening in aggregate. College attendance is way up over the last few decades, even at the graduate level. Sure, top schools are more competitive, but that is only because their is more to filter out, and newer schools would seemingly pick up the slack. Many of the less than reputable for-profit schools have pretty much no admission requirements (except $$$). I personally think this new evolving system is still extremely problematic, but not because of admissions.
Ask HN: Resources for a photoshop expert to become a web design expert?
A friend of mine is an amazing designer in Photoshop, illustrator, etc.

In terms of web design, he understands screen limitations but there are significant complexities beyond just that, especially when including cross browser compatibility with various CSS attributes.

What resources, including commercial classes, are available to take an amazing design guru and turn them into a designer that can also turn their beautiful work into HTML/CSS (scss, stylus, etc )?
Figured out? Where do we have long near-vacuum tunnels in a seismic area?
This is not seamless. I don't need to try it to find that out, I just have seen this type of extension enough times to know that it isn't seamless, especially in beta form.
I actually really like the idea of sandboxing and entitlements for Mac apps. It's appropriate for like 90% of all the apps I run and I'll happily click through a scary warning for the things I don't think ought to run in a sandbox.

For some developers the MAS is a really nice alternative to direct distribution. You don't have to setup a merchant account and deal with all that. Your apps are automatically searchable (if not really discoverable). You have a built-in review/rating system to establish credibility pretty quickly (which absolutely impacts sales). It's not a horrible system, and again, Apple doesn't force you to use it... unless you want to use iCloud, but then again there's nothing stopping you from doing your own cloud sync solution as Omni has done.

In the depths of the Great Stagnation, all significant technological progress occurs due to ascended post-exit Silicon Valley moguls personally funding it (with money they own or fully control) out of the goodness of their own hearts.

A Handwritten Letter the Prison System Doesn't Want You to See
This is actually one of my biggest disappointments with the Hyperloop announcement. Musk said early on that it wasn't a vacuum tube. But in the end, we have a tube with vacuum pumps, and an air pressure much lower than that of Mars. In my book, that is close enough to a vacuum tube that it sounds like purposeful mis-direction on Musk's part. I.e., when he said (when he first mentioned the idea) that it isn't a vacuum tube, it would have been more honest to say that it isn't a complete hard vacuum tube. Would have cut out on some of the more wild speculations.
Creating a series of books about javascript and node.js
The best notebooks I've found yet I stumbled upon in stationary stores in Greece. They are A5, 50 sheets, with flexible covers and small grids. And cost ~1.5 euro each (I bought 10 of them). They are school notebooks, similar to the composition notebooks we have, except a little thiner, with soft covers, and slightly smaller. I don't know where to get them elsewhere (this looks similar, but no guarantee: http://www.kapsis.gr/product.php?products_id=4127), but I wish I could - the size, page count, flexibility (they'll lie flat, can have the covers folded back) is better than anything I've used, and they don't cost $10 each (or $20+ for some of the ridiculous ones). Cheap enough that I use them for everything, but nice enough that numerous people have asked where they can get them. I just wish someone would import them / make a similar product here :)
"Not really, no. Anything under about 25-50 will feel instantaneous. Between 50-100 you're looking at something that doesn't consciously register as 'slow', yet feels vaguely sluggish - especially when it comes to responding to taps on a screen."

http://www.nngroup.com/articles/response-times-3-important-l...

Funny that you mention BB10; I used to work at RIM (a handful of years ago), and developer relations were disseminating documents that said application developers should make apps respond in less than 150ms to give the illusion of instantaneousness.

Mind you, I'm not saying YOU can't perceive the difference between 100ms and 25ms, but that in the general populace, the limit of perception is around 100ms.
As a VC the startups that don't exit are crucial to the analysis. For their purposes they should be included with an exit value of zero.

Say the startups with the highest (or lowest) funding all die before exiting -- that's a really important thing to know. That'd affect the regression outcomes (not to mention the decision-making process of everyone involved.)

This is a reasonable criticism, the other is not.

Firstly, the article in question is about the technical feasibility of hyperloop, which is in question because it's not something that's ever been done before and it's a non-trivial application of aerodynamics et al. Secondly, if you insist on changing the subject from one of technical feasibility to one of economic feasibility you can't just spew a bunch of opinions without backing any of them up. This article isn't meant to address the economics of hyperloop and implying that it should is unfair.
Why "Generation Y" is Unhappy
It's actually a relatively new problem. I live in a dense university neighborhood in Hamilton, Ontario (basically Canada's Pittsburgh) and I grew up being able to run free with my friends. I mean, there wasn't much in the way of raising stray animals or amateur carpentry, but the rest of that stuff we did. Lots of unsupervised mayhem running around the area.

I watched too much TV, and the mayhem was mostly confined to our local neighborhood and the ravine nearby, but we still played.

The thing is about my area is that it was built in the '30s. Before two-car homes. This city is so dense that a kid can walk anywhere, even though it's a pretty big city.

But now, living in the same neighborhood with my own kids, the culture has changed. I'd never dream of sending my 6-year-old son out to walk to school on his own and there isn't a mob of similar kids hiking to school for him to go with, and his friends aren't really playing out front on the street - it's all scheduled playdates.

Part of the problem is dual-income homes. It's only three blocks to school, but I drive my kids there anyways because I'm on my way to work... my wife is already at her job by then.

And this is the best-case scenario for Canada - a dense, pedestrian-friendly, close-to-school, close-to-the park house where kids can walk to anything. It's an affluent area with no crime to speak of other than drunken students. It is quite possibly the ideal place for kids to roam free... and they still don't do it.

And compare that to the rest of Southern Ontario that is one vast ocean of suburban tract housing where there is nothing in walking distance and all the houses and shops are in an ocean of parking and wide streets that makes even your neighbor feel a little further.
I am taking this from the founder's point of view, where no money is paid to buy the equity. You highlight the good point that it depends on the context and point of view - who's success is being talked about.
