That is one of the coolest articles on field engineering I've seen in a while. Thanks a lot for sharing it - it really brings out how something like the hyperloop can be tackled. So far, thermal effects have been my main point of curiosity, but the idea of calibrating the steel to take care of it will likely be the ... easiest? way around the problem.

At their desired vacuum pressures, the steel doesn't need to be anything special, so I would love to see the mechanical engineering that goes into designing the 5 mile track's materials.
Considering the small number of highly skilled, highly trained, highly capable people there are this population ratio comparison is not meaningful.

If those people are working on "colonizing" Mars they won't be available for saving earth.
Don't forget:

- Ceres (optimization library used for Street View alignment)

- Zopfli (zlib-compatible lossless compressor with better space efficiency)

- Kubernetes (cluster management framework based on Borg)

- Cayley (graph database)

- Gumbo (HTML5 parser in C)

- word2vec (NLP semantic analysis tool)

- FlatBuffers (memory-efficient alternative to protobuf)

all of which were released between 2012 and 2015.
Most of the article is not about why we'd be better off - not to say it isn't worth reading, but at the end we find:

"If Napoleon had remained emperor of France for the six years remaining in his natural life, European civilization would have benefited inestimably. The reactionary Holy Alliance of Russia, Prussia and Austria would not have been able to crush liberal constitutionalist movements in Spain, Greece, Eastern Europe and elsewhere; pressure to join France in abolishing slavery in Asia, Africa and the Caribbean would have grown; the benefits of meritocracy over feudalism would have had time to become more widely appreciated; Jews would not have been forced back into their ghettos in the Papal States and made to wear the yellow star again; encouragement of the arts and sciences would have been better understood and copied; and the plans to rebuild Paris would have been implemented, making it the most gorgeous city in the world."

Some arguable points, but Napoleon was... shall we say, capricious. It seems naive to think that all this would have happened the way it's put there.

Still, it makes for fun speculation. If you like that, you should read Creasy's "15 Decisive Battles in the History of the World," at least if you don't mind a bit (well, more than a bit) of Anglocentrism. There's a lot of this "if things had gone the other way" stuff and it's great conversation fodder.

Also, Hugo's narrative of Waterloo in "Les Miserables" is wonderful and worth reading if you are at all intrigued.
PDF can work really well. Prevents transitions and less worries about compatibility on the presenting machine.
A very interesting historical read with a biased view pro-Napoleon, but the facts seems pretty well explained.

Only the last paragraph briefly discuss the title, as if the author could have predicted the future for 150 years. But as the french proverb says: "avec des si on mettrait Paris en bouteille" [1]

I wrote mine, but I track tasks and milestones rather than time spent.

Time tracking makes sense for freelancers and other people who bill by the hour but personally I tried rescuetime & co. and I do not see the point in knowing how long I was on facebook or how long I spent editing a particular file.

Milestones require manual input but I find that information much more relevant.
The problem is, founders tend to try to solve problems they've experienced and understand. For the twenty-somethings that are the public face of "startup founders", they may not understand international trade or enterprise health care or other big problems, but they understand dating. So they write dating apps.

And then, by the time they've acquired enough real-world professional experience to actually understand some interesting and high-value problems, they have a mortgage and kids and don't want to eat ramen like they did when they were 22.

I don't disagree that other options should be tried; I'm saying that they likely won't work en masse. You'll always find artists who will find patronage through a small following, but we're not headed back to the era of large swaths of the music industry making a living off of their music.

Walk into your typical library. Look at all of the books on the shelves. Pick a random book. Pull it out. Imagine that book yells at you "I deserve more money if you want to read me!".

Do you pay for the privilege to read that book? Or do you push it back in and pick from the thousands of other books available? We are awash in cheap/free content, that's the problem.

OK, but are you a mainstream consumer? No, you're a developer and have specific needs that are solved better with native desktop software.

Slides exist to supplement what is being said. If your presentation doesn't work without the slides then you're doing it wrong

I'm torn. Yes, slides are a supplement. But a purely verbal presentation on things like financials or schedule without some supporting data feels like complete fluff, and while the speaker could be spitting out data verbally, that doesn't "work" when you have more than one or two data points - the audience can't hold lots of data in their head as you recite it. That's what visuals are for.
Opera had a nice presentation mode for such things.

I have seen also some pages with similar functionality, and a couple of flash apps.

Even a PDF created from Latex works wonders for that purpose.
I'm in favor of that, but my education has included plenty of powerpoint education. For context, I'm 25 and attended a typical Canadian high school and community college. We had units on presenting material in every english, social studies and "life skills" class in several different years in high school. Usually the classes included all the guidelines for delivering a high quality, useful presentation.

Same in college - we had a whole class one semester dedicated to learning how to present material effectively using powerpoint. Even still, my classmates would insist on giving boring, monotone lectures with far too much info on each slide. It got better toward the end of that college course though.

My takeaway from all that is that public speaking and presenting are DIFFICULT skills, that require not just a couple weeks of instruction, but many years of intensive instruction over the course of a schooling career. People do get better at it, but it takes a lot of work to get them there. Blaming powerpoint or any other tool is a simplistic approach that doesn't help the problem.
> Not at all, YT solved it many years ago with ContentID.

Sorry, there is some ambiguity in English about this. I am regarding a "solved problem" as a "problem" (i.e. classification) whereas you are regarding it as "no longer a problem" (i.e. interface). Yes, right now YouTube's interaction with the problem is highly limited (though not nonexistent), but if one is, say, trying to disrupt YouTube or talk about YouTube's history, one still classifies it as a problem in general that exists within YouTube's problem domain.

> Now imagine having to install all the plethora of apps on every device, one for videos, one for music, 500 for different types of documents, etc. Instead, you install a (hopefully) standard-compliant browser, and done.

I mean, I agree that it helps that particular problem somewhat to have a cross-platform virtual machine (the browser) and to distribute an executable (your JS app) on that machine rather than (or sometimes alongside) your content. This also creates its own problems, of course, like simpler browsers (spiders, text-only browsers) not being compatible with your website, as well as some new buggy issues when, say, the JS doesn't load properly. But HTML+CSS+JS is not new in this town and the cemetery has some gravestones -- like the fact that there aren't many desktop Java applications, the complete failure of the Java browser plugin, and the waning of the Flash plugin. It is peculiar among these only because its dreams are less lofty: not "write once run everywhere" but "write once, then write a (hopefully graceful) downgrade path if they do not support the features that I want to use."
And what are the odds of that, in a field already saturated with both successful, established competitors (OKCupid, Tinder, EHarmony, etc) and a thousand other would-be viral newcomers?

And even if you could overcome the competition, you still have all the other problems Andrew Chen wrote about... how do you make money? How do you grow without spending a fortune? How do you exit?

Yes. Meeting people you're potentially compatible with. I met my current girlfriend on OKCupid a couple months ago. I'm in my early 30s, never married, and have an increasingly stringent set of requirements for a potential mate[1]. Meeting people I find interesting is challenging.

I really like when people put a lot of information on the slides.

It makes going over past presentations very easy. For example, when a new ML algorithm comes out, the only way to easily grasp how it works without reading a bunch of papers is to find some Power Point slides by the author. I guarantee people wouldn't make two sets of slides either.

PG's "What Microsoft is the Altair Basic of?" applies really well to Snapchat.

Advertising is something necessary in the capitalist system, advertising won't disappear anytime soon. The aggregate value comes when it's blended to the UX through smoother mechanisms. That's Snapchat's philosophy and a lot of other companies will opt for that philosophy as well.

Bruce Haack was a genius. There are songs on The Electric Lucifer[1] that would sound ahead of their time if they came out today (and that record was released almost 50 years ago). Of late he seems to have been canonized as one of those auteurs who is totally unappreciated in his time but winds up influencing everybody.

The experimental children's records mentioned in the article are absolutely worth your time, as well as the aforementioned Lucifer, but anyone interested should also hear "Party Machine"[2] (co-produced by Russell Simmons) and the 32 minute epic "Icarus"—both bonus tracks on Haackula[3], a 2008 collection of previously unreleased material. There's also some really good stuff on Bruce Haack Remixes[4] which came out on Stones Throw in 2012.

One of my favorite rap songs in recent memory is Micah James' "Blow Job (Give Up)"[5] which samples and builds on a Haack song by the same name.

There isn't much in the way of entrenchment at reddit. It relies on a constant flow of new material to remain engaging. It's not like users stick around to read years-old topics in any great quantity.

Basically it could be replaced really, really quickly. A mass of users is no particular guarantee when you don't bring anything fundamentally unique to the table, and all reddit really does at core is build forums around the content of others.
I guess I've always misunderstood blackholes. I was under the impression that they were simply a vacuum created as a by product of the every expanding "space". Sure they are sucking things up and growing, but space is always expanding.

I offered similar thoughts when Dating Ring first launched:

YC's public persona is all about "hyper-growth" and building "very large" companies[1]. But if you go through the list of companies it has funded, a good number would have a very difficult time making a prima facie case that they fit the profile of a business that can achieve significant growth and scale. Dating Ring is the perfect example of that.

There are numerous challenges associated with breaking into the online dating space generally. First, the costs of customer acquisition are typically quite high because there's so much competition. That makes it very difficult for new services to gain traction without significant investment in advertising. Second, there's an additional level of churn built in to this market because when a dating service works, it loses customers. That produces a constant need for investment in the aforementioned user acquisition which is so costly.

More specifically, Dating Ring seems to be positioned in no man's land (no pun intended). It can't compete with the quantity and immediate gratification of online services that cost nothing or roughly the same, and it can't compete with the quality and exclusivity of matchmaking services which generally have costs signaling much higher value.

If the OP's comment is true, Dating Ring would ironically appear to be offering the worst of both worlds by trying to package users from the former as part of a service masquerading as the latter. Even with adjustments to its model, the odds that this company ever achieves "hyper-growth" or becomes a very large business are next to nil.

None of this means that the founder hasn't experienced sexism, but she seems far too eager to ignore the inconvenient fact that some early traction and an impressive team don't necessarily mean you have an investable business.

If native won, then why didn't "native" desktop software win? Everything on desktop has moved to SAAS and on the web.

That's a common belief but isn't correct, of course. Otherwise ChromeOS would have crushed the competition and it's hardly made a dent.

Many, many people use and heavily rely on native desktop apps every day. Usually for getting real work done once they tire of procrastinating on hacker news/facebook/etc :-)

Just consider the importance of MS Office to the global economy!

This is despite the fact that the shepards of the native desktop app platforms all screwed up big time and dropped the ball in major ways allowing the totally unsuitable yet somehow still good HTML platform to take over:

• MS/Apple/etc STILL have never shipped non-terrible software update mechanisms. Only Google managed to get this right and their online update engine was basically just for them.

• No discovery or sandboxing mechanisms worth a damn.

• Heavy reliance on languages like C++ that many developers can't handle (whereas web was fully built around scripting languages)

• The only people who cared about doing cross-platform desktop apps were Sun and Trolltech, and they sunk into the swamp of pretending to be the real OS-specific widget toolkits. Web apps collectively said "fuck that shit" and we saw a glorious explosion of styles with every web app branding its own widgets differently. Users, it turned out, wanted attractive apps rather than native-looking apps and so the web won on this count even though the HTML widget toolkit is a joke.

• Speaking of widget toolkits, the web is so primitive that it forced developers to abandon UI design paradigms that were actually rather user unfriendly, but commonly used because the platforms made it so easy. Prime offender: tree widgets. Hardly ever used these days as they have terrible usability. HTML has no such widget. Also: context menus. Users never find things in them. HTML simply doesn't let you customise the context menu at all.

So the combination of uber-simple programming languages, a cross platform UI story that ignored the massive must-look-native timesink, clean/invisible online updates, etc ....... almost by accident it ended up being compelling.

Now compare to mobile, where native apps are doing a lot better. Android is Java based so no problem with C++ being unapproachable. Objective-C kind of sucks but is still easier than C++ in many ways, plus iOS is big enough that developers just have to suck it up. There's built in sandboxing and app updates have been a part of the platform right from day one. The widget toolkits are way more modern and result in simpler/more intuitive UIs than classical desktop toolkits, so dysfunctional design patterns like nested trees with tiny icons don't crop up. The toolkits almost force simple, intuitive designs. And because mobile is (a) very new and (b) very restricted, writing the app twice with two different user interfaces isn't necessarily a killer problem, whereas for gigantic mature desktop apps with a 20 year feature set like Photoshop/Office it's just really expensive to do that. So the not-quite-native issue is less prominent.

The irony of course is that after the Apple engineering team spends months trimming off that extra millimeter of thickness, most of their users still go out and get an otterbox that triples the thickness.

Of course, even if they designed an iPhone only twice as thick with triple the battery life and no need for a case, it would still be panned.

I doubt this has much to do with traffic. It can be explained by another observation: on average you spend more time in slow lanes.

The checkout at a supermarket has the same phenomenon. Let's say with 50% probability you choose a line that takes 10 minutes and with 50% probability you choose a line that takes 20 minutes. On average now 67% of the time the other line will move faster.

you bought more cable than you needed for your internet connection.

What?

Second problem: you tried to use DRM.

I didn't. The cable company did. And plenty of the TV I am able to record is not available to stream on the same day, if at all.
Relatively, pretty much zero.
I am not exactly in the target market at 37 years old but I definitely see it as solving a problem.

If you live in a Rural area for instance, and work near your home your chances of finding a mate are pretty slim. Especially in those small towns where everyone pairs up in their late teens and stays together. There are people who can go for months at a time without meeting anyone new.

Then there are the people who just can't strike up a conversation or pick up on people. I don't say this disparagingly, approaching someone of the opposite sex can be downright terrifying. Hitting on a taken/married person is not only a bit embarrassing but it's a subtle reminder that you are alone and everyone else is taken (at least that's what you tell yourself).

Finally, on the other end of the curve are those folks looking for casual sex. Dating apps like Tinder are fast and easy, they become a buffet table of human beings you can peruse anytime you want. Without laying any judgement on it you have to admit that it is a problem being solved.

Open sourcing a product by definition is not smart. A product is a solution to a problem that is meant to be sold. A library is a tool that enables others to make their own product but open sourcing for example Gmail would be the dumbest thing Google could ever do.
Selling an unready product to retail investors indicates more of a desire to pay themselves six figure dalaires for 5 years and then somberly declare the thing a failure.
In the article they quote someone as saying if you lose the vacuum everyone crashes? That seems to be exactly opposite what I read in other articles. Is that true?
That seems extremely painful without explicit page break characters, because if you were to rewrite anything, you would have to adjust the corresponding whitespace or else everything would get misaligned.
You're being rather argumentative, don't you think? Did you have something worth elaborating with the bit about the random walk? I would still be curious to know.
