While the couplings certainly are a factor for heavy (bulk) freight (steel, coal, ore, aggregates, etc.), I'd guess that container trains are often rather length-limited by all the rest of the infrastructure (yard/siding/loop length, signalling) before hitting the actual limits of the old-style screw couplings. Whereas e.g. most of Europe currently has evolved towards a maximum length of around 750 m (which doesn't mean that the infrastructure in terms of loop/sidings length actually allows trains that long everywhere, though!), Denmark allows up to 835 m while still using screw couplings.

So for container trains at least, a programme of loops and sidings lengthening would be the more pressing requirement, before actually and absolutely having to upgrade the couplers, but that kind of infrastructure modification doesn't come cheap or necessarily easy, either.

Another difference to consider is that in Europe, passenger traffic is much more widespread and common than on North American railways, and also commonly has priority over freight trains.

While in principle, longer trains are indeed more efficient than an equivalent larger number of shorter trains, past a certain point they'll eventually become too unwieldy to fit inside the schedule demands of passenger traffic. There's certainly scope for moving beyond the current 750 m maximum, but the multi-kilometre range would probably be pushing things a little too far without completely dedicated infrastructure.
What I want to see is not heroic drivers like NASCAR, nor heroic billionaires investing in very similar tweaks, like Formula 1, but a diversity of creative conceptual engineering, competing in the same challenges, for lots of money.

Things like DARPA sponsors: The Grand Challenge in self-driving cars, and the Robotics Challenge. The Ansari X-prize also applies. BattleBots was a decent attempt at a sport along these lines. Fields where true novelty still exists, and there are no consistently obvious paths forward.

My impression as a non-fan is that Formula 1 only achieves divergent innovation on rare occasions, and next season or two everyone is doing it or it's been banned by the race sponsors.
I never know how to feel about mathematically/programmatically generated art. Despite having done a bit myself, I never think it actually looks good or artistic.
If the point of HN is sharing information, and having substantive dialog, then these links are counter-productive. If really think we should ban non-traversable links; if there are alternative links to submit that are the next best available summary or secondary source, I think that would be far preferable (and we can always relegate the primary paywall-ed source into the comment page).

Should I continue to "flag" paywall-only links as I see them, or just continue to gripe in the comments?
The SEO industry justifiably has an awful name, and I certainly understand where you're coming from, but there are some who have a different purpose:

to get higher in the search results list by making results you do want to see.
I would also like to mention my project: pydeeplearn. You can find it here https://github.com/mihaelacr/pydeeplearn. I think it's main advantage is that it uses theano under the hood but the user does not need to know theano at all. The most complete implementations are those of RBMs and DBNs, but I also have CNNs. The library has support for adversarial training, as presented in the paper "Explaining and Harnessing Adversarial Examples" by Ian J. Goodfellow, Jonathon Shlens, Christian Szegedy. I recently also integrated spearmint into the library, so hyperparameter optimization comes in for free.
There's a pretty well known plugin that does something similar to this in Java land; https://infinitest.github.io/. Integrates with both IntelliJ and Eclipse. Works wonders.
That's up to you. All I am saying is that you are missing out on something if all you judge it on is how much CPU is being used.

Kind of like judging code on what typography the editor uses to display it.
That is such a thoughtful question - thank you! What we have seen is that the upbeat music, because it comes with a very strong BEAT give the mind something EVEN more concrete to focus on (the beat, the breathing pattern, and the teachers voice all serve as the object of attention, like a mantra) - so it does in fact make it easier to cultivate presence for people who find traditional objects of focus (e.g. "following the feeling of the breath") hard to anchor attention on. Regarding the social aspect - what we have found is that going through the class allows you to connect first to yourself more deeply, and then being in that headspace after class opens you up to be more connected to the others in the class. For more extroverted people that can manifest as sharing with the group about their experience - but even for some self proclaimed introverted customers we have talked with, they say knowing that they are sharing the experience with others and just listening to what others say at the end makes them feel less alone in the world.
I think a Dune project aimed squarely at capturing Jodorowsky’s original vision would have tremendous traction. It would be perfect for the 3D techniques developed for Avatar. The techniques in Pixar's palette would be awesome if turned to this purpose, especially if they used a different art director for each planet/culture.

Lord of the Rings was covered by Bass and Rankin and Ralph Bakshi animations before WETA's LotR movies. It was LotR that finally did full justice to those properties. (Though I really like Bakshi's movie. He just didn't have enough funding to do 3 movies.)

If I were a Pixar competitor, I would look seriously at Dune. The religious/economic/political issues Dune covers would really resonate right now.
There are a few components involved in this disaster:

1) The "system" which, in the article, refers to the standard procedures and best practices one should follow when monitoring and running an oil well of this type. From what the author said, it appears that if the people at the well had followed these procedures the blowout wouldn't have happened.

2) Human error -- people being careless, rushed, drunk, tired, not understanding procedures, etc. This is the "people aren't immune to screw-ups" factor. It's not clear how much this applies to this particular incident.

3) There's another sort of "system" that 1) and 2) are embedded in, and that is the system of incentives in which people operate. This includes things like your manager pressuring you to "do it anyway", or knowing that your promotion depends on cutting corners and being under budget. I suspect that this is the root of the problem, in this case.

One reason these incentives are the way they are is because they often work --- the company saves money (or the individual gets his promotion) and even when things go wrong the cost of the failure may be less than the money saved (though, that likely won't be true in the case of BP). Other reasons may involve not fully understanding the risks, or principal/agent issues.

I understand what the author is trying to say, but I find the language very confusing. To say that, you need to be creative and intelligent to be able to deal with crap sounds correct in theory, but in practice it is the worst use of these skills. To deal with crap, you have to basically "suck it up" and swallow you pride. Thats it! Ultimately if that is a large part of what it takes to succeed at your job, then you are basically adding a lot of noise to both your career and the success of your company.

No it's not. The whole purpose of having an app store is to make it more general purpose. Why should anything be 'off limits' just because the device is small? Why is this not obvious to you?

.. and it never will be. But you added the word 'development', not me. I prefer to decide how I can use my computation devices and when they do not allow this then they should be regarded as toys.
But it isn't really isn't that black and white is it? A rich family could get a break on this property to build a Trader Joes there, but how long has the property been vacant? Maybe no one else wants to build there and this "subsidy" is better for the community due to the employment a Trader Joes and other businesses could provide.

Right now an empty parking lot isn't helping the community much; this should also be taken into consideration.
Because there are fewer women then men in the technology space, they're a scarce resource. Startups who want diverse teams need to compete for them.

Also, parts of the YC universe have a bit of a reputation for being uncomfortable with women. Reaching out sends a clear signal that you're not like that -- you're the kind of company that wants women to work there enough that you're willing to take the initiative.

I think that's really cool! Next step: parse those stories using a BDD framework! Looking at that interface brings to mind something like lettuce.it

You could parse out the comments into a separate story block then write in the features/notes from lettuce and have them link back to each chunk of the code - providing coverage reports and the like.

Now it just needs a vim plugin ;)
IMO, the reason it doesn't exist is that "no information overload" and a site as the one you describe, "a central place", are mutually exclusive.

Seeing as plenty of people often use a computer that much or longer on a regular basis (not counting breaks to eat or go to the bathroom, obviously), I'm not really convinced it's just the how long you use a monitor. I'd suggest talking to an ophthalmologist for real advice.

That said, I think the usual line is to take a ten minute break every hour. Should be good for your legs, too. But really, talk to an ophthalmologist.
This marks the first time I have ever enjoyed being in a queue.

Anecdotally, I'd concur with the author. Most of my education seemed irrelevant. I learned to program and understand math because I wanted to make computer games.

Honestly, you should be taking breaks. Spending 8+ hours a day on the computer is typical for somebody working hard, but taking a break every once in awhile is still essential.

In fact, I've heard a lot of people say that the 30-30 rule has helped them be even more productive. Spend 30 minutes doing hard work on the computer, and then 30 minutes off letting your brain relax.
If a bank accidentally leaves a sack of cash on the sidewalk and you take it, it is not yours. Plus they didn't declare any of the money and instead laundered it through a bunch of sham companies and fraudulent users on crypto exchanges.

A lot of POS's support contactless payments, but they were kind of flaky for the first two years, and...oddly slow.

I'm not well versed in BTC, so my prices may be wrong. But this is webscale in a way I haven't thought of before.

It is alleged they stole 119754 BTC, which in 2016 was < $1000USD. Which would have been < $100,000,000. Today, it is worth 5bln. (not that 100mm is nothing.... but it is a lot less).

In addition to my own experience, Guy Kawasaki also said that his blog posts took him about 8 hours to write on average. He's sort of the archetype because originally every single one of his posts was approaching the platonic ideal, and he made the technorati top 100 only a few months after starting his blog.

In general though it's not that hard to tell roughly how long a blog post took to write just by reading it. The typical breakdown of a successful blog post is usually something like:

1) Two or three hours of reading a few journal articles or digging up a bunch of facts and citations from Google.

2) Two or three hours writing down what you want to say in roughly the order you want to say it. The sweet spot is usually 800 to 1200 words.

3) Another two hours restructuring the writing so that your the voice, flow, formatting, grammar, etc. maximally resonate with the people who you ultimately want to upvote your post.

4) Another hour or two polishing the post, especially the first two or three paragraphs so that you can maximize the amount of people who actually read what you write once they click on the link. Also optimizing the title, coming up with a snappy conclusion, making sure the whitespace is aesthetically pleasing, etc.

5) Another hour to turn the post into HTML, make sure all the links are working, fix HTML formatting issues, correct last minute typos, and go live.

If you spend longer than this doing research and coming up with more original ideas then your posts will no longer resonate with as many people because even though it's more insightful, it's less anchored to stuff they already know and accept as true. And the only people who can really do a good job faster than this are those who can get away with writing in the same voice they speak in, which is very few people because most people aren't very good at speaking. So generally only people like Seth Godin can do this and still get lots of upvotes. Similarly, you can also shave off some time if you're someone who can draw on vast amounts of professional experience in addition to research, like Fred Wilson. But again there aren't that many people that can do this and still be credible, because even if you're legitimately a well-recognized expert it still only works for people in a handful of professions.

In general you will rarely see Paul Kedrosky's blog making the front page here, because most of his blog posts are just a list of new statistics without much explanation. And even though these are often brilliant and have the potential to completely reshape your worldview, people apparently have trouble understanding the implications without any further explanation. And similarly, rarely do Salon.com or Edge.org articles make the front page; people have trouble believing that Salon articles are true because there's a lot of research they haven't heard before so they think that it must be false because if it was true they would have already heard about it, and in the case of Edge.org people don't like to think for themselves about whether or not the vast amounts of original ideas are likely true.

Then have a look at vega and its abstraction layer vega-lite [1]. It is based upon a grammar which allows you to constain the kind of visualization you would like to have. The rest is filled in by the vega-lite compiler. I've been toying around with it lately, and I am really impressed by it.

As a French my definition of a documentary is what Arte produce.

> gold standard adjuvants

I think the mRNA vaccines don't contain any adjuvants at all. They are so awesome, because they are comparatively simple systems.

I would choose the mRNA vaccines over adenovirus-based ones, because of that. Drive-by immunity to the adenovirus carriers could render future vaccines useless, when there is no alternative vaccine technology available *. I hope when it's my turn, I will have a choice.

* Edit: My guessing. I am no medical professional, or researcher in a related field. Maybe my worries are completely unsubstantiated. I am also of the "worrying type" https://www.youtube.com/watch?v=pUDv3h09VBc
A single retraction is completely understandable. It's easy to make a mistake.

But the NYT has a long history of one-sided bias. This is part of a systemic problem with biased media. (There are examples on both sides of the aisle, of course.)
Considering it cost about $2-$3 to create and ship the hardcover book to amazon, depending on amazon's cut of the kindle book, the publisher might be making more money on the hard cover.

This is going to sound somewhat shallow, but I hope this new installation gets some decent visual design. Look at some of the classic supercomputers, such as the fantastic Thinking Machines CM-1: http://www.mission-base.com/tamiko/cm/CM-1_500w.gif

Now look at the current reigning champ in 2010: http://www.blogcdn.com/www.engadget.com/media/2010/10/mod-65...

Sure, the visual design of a supercomputing installation doesn't have any bearing on its actual utility. But having a certain presence commands respect—even if the researchers using it know it's just stagecraft, there's an undeniable attraction to working on something that isn't just a great engineering achievement, but also looks the part.
I'd guess they have a very high drop-out rate.

Regardless, "machine learning" is a very broad field and honestly I have no idea what an "ML engineer" is doing if they are one. It can cover any of the following:

1. Cutting-edge academic research (do better on this test set)

2. Doing data analysis to identify prediction ability

3. Creatively thinking of useful features to evaluate.

4. Implementing data pipelines/logging to obtain the features needed for #3.

5. Production systems to evaluate/train ML systems. (multiple places in the stack).

Because the spectrum is so wide, if you are already an engineer, you can readily get into "ML" categories 3-5 and even 2. Andrew Ng's course is a valuable introduction and not that heavy of an investment -- I found that just with it (alongside my product and infra background), I could readily contribute to ML groups at my company.

which x are we talking about? (Logically that example is crap because only the alias x makes sense, but something like that anyway).
