Of course it's available in Ruby. You just don't get ahead-of-time verification without lots of extra trouble (implementing it yourself). The problem is not that you can't specify pre-conditions, and use the type system to do it.

The problem is that either you create specialized IR's for each stage, or a lot of this is expressed through tree shape, and it's just painful to mentally keep track of more than it is painful to test.

I remember a popular unicorn founder (can we just call it that) once referred to himself as "opportunistically lazy". That certainly fits with the technical persona since something within makes us averse to repetitive work.

But now it seems that we've automated pretty much everything we could, so where to now for the technically minded lazy opportunist?

I couldn't say really, can't say I'm a big fan, but it's relevant that multiple big companies are using this kind of interface. I would hope they have some reasons beyond UI flashiness and copying their competitors.

Whatever the reasons, when a customer says "build me one of those" it's useful to have a good library to call upon.
Do they really believe what they write? Maybe it is just plain laziness and they are okay with being wrong as long as they can fill their quota of articles?
Matrices can be thought of as the coefficients to linear systems of equations.
Things that linear systems of equations can do to their input variables are rotations, translations, scaling etc.
Perspective distortion is another linear transform so it can be represented by a matrix.

An "entry" at least implies there is a list somewhere (as would "element"). Both "item" and "entity" are more like "thing". I could see adding "object" to the list.

it was mentioned that the condition develops gradually from the normal brain. So it seems pretty plausible that in some people the brain successfully rewires in parallel with and in response to the development of the condition so that direct white matter connections get functionally replaced by some kind of mesh-style network in the gray matter layer. While this may suggest that typical amount of white matter may be not strictly necessary, the significantly less than 100% success rate of such rewiring may explain why evolution hasn't gone this way .
The Fairphone 2: A Review after 1 Week
>The Supreme Court, however, declined to hear the case, strongly implying (or maybe directly indicating?) that it thought the decision was correct.

As the court emphasized in Missouri v Jenkins (1995), "[t]he denial of a writ of certiorari imports no expression of opinion upon the merits of the case" (https://www.law.cornell.edu/supct/html/93-1823.ZO.html)

While ideal from a theoretical perspective, as a practical matter, can you imagine renaming a 10 GB file by first creating a copy of it, and then deleting the old version?!?

That kind of inefficiency is not practical for most real world programs!

To solve this problem, we can write an optimizing interpreter, which is a special kind of interpreter that can detect patterns and substitute them with semantically equivalent but faster alternatives.

But why?
Some people choose to take 20 years of monthly payments from lottery winning rather than one lump sum. "Rationally" anyone who does that is a fool, and yet people constantly do that. Perhaps there's value to variance minimization, aside from the non-linear utility function of money?
1) The OpenGL standard specifies functions that are capitalized like that, as "renderbuffer" is a noun.

2) NUL is a character, while NULL is a pointer. These APIs are using the correct name for each scenario.

3) Checking if the user is a monkey (or now a goat) is a running gag. I don't think that is a naming mistake.

4) The usage of "exception" in that name is clearly different each time, though maybe it requires knowing Objective-C for that to feel "correct" (as the developer who named that function clearly is writing Objective-Java there ;P).

The spelling mistakes and inconsistencies are "awesome", though :(.
That does not seem to currently be legal under the T&C, unfortunately.

Yeah, it's sad how they caught Sun in their web and laid their eggs in its body. I was hoping IBM would buy Sun, and give the body a decent burial.
Of course I am not defending jailing journalists. But there is something a little deeper here. During 2013 and 2014 there was an unprecedented political power struggle between Erdogan and Gulen ( http://www.city-journal.org/2012/22_4_fethullah-gulen.html ) whose cult has/had deep roots in the government especially in the police force, bureaucracy and justice system. They control many media outlets. After the breaking point, their sole aim was to overthrow Erdogan from his position, either because he started to block their spreading in the state, or because he simply did not want them anymore.

So they throw whatever they have in their hands, probably with a lot of manipulation. They attacked him and his family quite strongly with corruption claims (I would take them more seriously if there wasnt another motive behind all that). One of the attack point was about Syrian conflict. Probably government was supplying logistics help to the rebel groups fighting with Assads government but using their people in the key points they actually interfered with this action and presented this as if Government is helping IS. These journalists in question were also used as a proxy for spreading this. Now that Gulen has lost the battle big time, Government is taking his revenge by making some of their supporters lives miserable. But although they are now in the shadows they are silently continuing their attacks. From my point of view, Gulen's secret cult's utopia is more dangerous than Erdogans bravado. At least he is honest on what he says, no matter good or bad.
Maybe that's why many New Yorkers believe, to an almost fanatical degree, that it's the best city on earth. It's the only way to resolve the cognitive dissonance that comes when you realize its shockingly poor quality of life.
There is already "medical tourism" happening in India - there are companies that organize everything, all one has to do is go there, get surgery (or whatever treatment), then go sight seeing before returning to the US and the cost of the entire trip would be less than what the procedure would cost here. Only downside is, it is driving up costs for the locals.

> In 2005, in France, the "referendum on a European Constitution" lit an immense debate, and there was an incredibly well-formed decision on an enormously obtuse tome of legalese.

On the contrary, the outcome of the referendum was less about the merits of the proposed constitution, and more an expression of growing anti-Establishment social opinion and a demonstration of discontent with the majority parties and President Chirac.

> If you think people aren't able to think and decide autonomously for themselves, you are actively opposing democracy.

If you think people aren't able to determine how to choose reasonable facsimiles of their moral/social/economic position through which to abstract their effect on the daily operation of a state, you are actively opposing democracy.

Being able to choose when and how to make decisions must be a core component of the free exercise of democracy.

That page isn't a complete listing, but you're right, only ~100 of the books seem to be properly open access, unfortunately. I guess Springer can decide to revoke access to the rest at any point in the future.

Edit: looks like they've revoked access already in fact https://news.ycombinator.com/item?id=10811854

Yes, so the network is marked as "equal to normal". Like O2 and eplus do.

But there’s no way to mark a network as better than normal.

For example, if you connect to WiFi, Android will recognize it as a non-mobile network, and start doing updates, etc. If you start listening to a song via Play Music on WiFi, and then go out of range, it will automatically downgrade the quality, or stop playing and ask you if you want to continue.

If you are on "NYC 4G", and go back to your own 4G network, there’s no way for Android to stop streaming that FLAC song, because it doesn’t know a way to tell that one 4G network is equivalent to WiFi, but another is not.
"The Internet infrastructure which is not free, the hosting of Internet content which is also not free"

This is not new, it's the story of how Internet is built and run, but so far it still remained free because there is value to be had in sharing a common infrastructure as opposed to everyone building his own network over and over again to cover the same place. So now comes Facebook and leaches the common "free" network built and paid by others, and then extends the Internet network pretty much in the way it was done till now but it doesn't offer it back in the same way! In this light I think that it would only fair if people start asking their network infrastructure providers to cease their networking service to Facebook! Let them extend and upkeep their own separate infrastructure on the whole Internet scale if they choose to do so!

This has been running since 2013, originally on my Medium blog. It's totally distro and tech agnostic: you could wrap it up any deploy tool you like, on any cloud provider. A little extra attention is paid to AWS and DigitalOcean since they're so popular.

The aim is for developers to understand what they're doing and why, make their own decisions and modify the process to their needs, rather than take someone else's pre-cooked environment without understanding how it was built.

Careful about that though. If you have typical computer-user posture, you'll often have a weak back and tight chest muscles. If you jump into bench pressing (as everyone does) without correcting the imbalance, you can make it worse. Essentially I'm saying a big yes to weight-training, but beyond learning the basics of how to lift, your initial focus should be correcting any existing postural issues, ideally after talking to a physio about it.
None of the links work for me, even though I was able to download a few hours ago. I have the option to purchase...
Same here. I tried one hour ago and could get one and now is all "Get Access"

Bad Springer :(
I'm now seeing "Get Access" (i.e., pay money) instead of "Download Book". I wonder if Springer shut this down? Or if there is some quantity or rate limit on the downloads?
Seems to have gone dead. Maybe it was a bug at Springer or a brief promotion.
While this may have been true when it was posted it is no longer true. If you think about it the idea doesn't make sense because the still living authors still want a cut. It's unfortunate because it's very difficult to find good textbooks just by searching yourself because the prices are so high.

> I bought my current vehicle, a Toyota Sienna minivan, largely because I was immediately comfortable when I got behind the wheel for a test drive. My entire back was supported, so not a twinge was felt there, unlike what happens in many other cars. I could also easily see over the steering wheel without tilting my head back, which is not the case in most other vehicles. And I could reach the floor pedals without unduly extending my leg and straining my lower back.

Advice for the author and anyone else with a similar predicament: you can replace the seat, steering wheel and pedals of any vehicle with one or two hand tools. Choice of aftermarket parts will be greater for more popular models. There are some generic parts as well, with little adapters to fit different models. Steering wheel height is adjustable in most cars, as is seat position... I would not recommend buying a car just because the default configuration feels comfy.
No spam. Please let's be tolerant
I don't buy the idea that the authors all still want a "cut" so to speak, given that many authors (at least in statistics) make copies freely available on their websites. I know Shumway did with the time series text and I beleive Lasserman did as well.
Ask HN: How do teams co-ordinate the dev of different web apps with one DB?
So, in our start-up, we're at a perplexing situation where we have a single Postgres database and multiple teams developing different web apps in Java, Clojure & Rails. We're facing a problem when the db schema changes, then everybody has to update the code, check for regressions etc.

I wanted to ask how other companies/start-ups who have multiple components usually deal with this problem.

We're currently looking into Thrift/Proto-Buffer. Let us know if there are better options. Thanks, folks.
Seems like demand was so high they had to kill it. I guess that’s what happens when you hit first page of HN, there must have been thousands of geeks downloading books by the dozens. Well it was good while it lasted. Managed to download a few books. Better luck next time/year.

Why can't we have the things without the networking stack, then plug them into something (upgradable and open source) with a networking stack?
And for good reason, in my opinion. Perl, Python, and JavaScript are nowhere
near being functional languages, but they all allow creating functions (those
are typically called "closures") and passing them around.

Yes, all these languages allow for functional programming, but it's not their
primary paradigm, and not the one that is only natural when you use the
language.

There must be something different that makes a language functional.
Thanks for the link.

I am mostly aware of how bad farming is in regards of how animals are treated or what effect it can have on the surrounding environment. My entry to this rabbit hole was the huge pig shit lakes near some of the most industrialized pig farms. From there there is no illusion that most research would go into more 'humane' treatments, but at the same time there is a strong enough incentive to have balanced medication to keep the animals alive while leaving as few substances in the meat as possible.

I'm not sure that research is moral or goes in the right direction, but I just suppose there is a decent amount of it given the scale of the market.
Umm, what happened? I clicked on a few of those titles below and its asking me to PAY!!!

Ah, but who does the CEO work for?

Just as the CEO will fire a VP who failed to execute on what the CEO asked, so will the board fire the CEO for living up to their expectations.

But boards usually want things like revenue growth... stuff shareholders care about. Capital doesn't care about diversity because there's no concept of a market where greater diversity has a value which can be traded.

All of which is of course another way of saying the problem is systemic. As we know. But there is more to the system than the CEO. (If we're talking founder CEOs that could be a different story, they could explicitly define the firm as one where diversity is a first-class goal.)

Basically, I am agreeing with the thrust of the article but saying that the problem is even worse.
Yes. Imagine you have a cube plotted in XYZ coordinates. The eight vertex points are (0,0,0), (0,0,10), (0,10,0), (0,10,10), (10,0,0), (10,0,10), (10,10,0) and (10,10,10).

Now let us say you want to rotate that cube 30 degrees on the X axis. You take the last vertex and make it a matrix, adding 1 at the end like you will do with the others, i.e. (10 10 10 1). Then you multiply it by the X rotation matrix ( https://open.gl/transformations ) using the appropriate angle. You now have the new correct position of that point. Now do the same for the other vertexes on the cube. The cube is still the same size and shape but its position has shifted.

You can do other easy transformations with matrix math. You can scale the cube with a scaling matrix - doubling it, halving it, or whatnot. Just multiply each vertex to the same scaling matrix. The new coordinates have the same size.

You can have a translation matrix to, where each vertex is multiplied by the same translation matrix, so that the cube is translated x, y, z coordinates from its origin.

You can also chain these matrix multiplications, so that the cube size is doubled, then rotated 60 degrees on the Y axis, then moved 20 X, -30 Y, 15 Z via translation. So that is multiplying three matrices in a row, then multiplying them against each vertex.

Ask HN: Why is TrueVault leaving python for java?
I noticed this job posting yesterday (https://news.ycombinator.com/item?id=10810547) stating that TrueVault is looking for a Java engineer to completely rewrite their platform in java instead of python.

As many of us here use both languages from time to time, and the pluses and benefits of both have been discussed and debated over and over, it'd be really nice to hear from them why they're leaving python and lessons learned, if any.

Can anyone comment on this?

Thanks!
> This comparison makes no sense. The vast majority of drugs are super cheap, and we have more choices then ever before. Only ones developed in the last 20 years have patents.

If as you say the majority of drugs are cheap, varied and didn't need patents, I'd say it's as good sign as any that we don't need patents for drugs.

I also think we need more research, both public and private. I understand that the current system relies on patent money to sustain itself, but I just don't buy that it has to be this way, or that it wouldn't work otherwise.

For the record I am not comparing industries, just saying that different models exists.
