rtb··on Ask HN: What are the greatest discoveries in the last few years?
Using water, air and large amounts of heat.

(Where does that heat come from? Many possibilities, but currently from fossil fuels.)

rtb··on Jump – Experiences like you're actually there
That's the power of Virtual Reality
rtb··on Reactive Streams for the JVM hits 1.0.0
> there's other established terms for what that means

Please could you expand on this?

rtb··on I’ve never seen such a copy of my work
I think you mean "copied", not "stole". Bild am Sonntag can continue to use their layouts.
rtb··on Under Pressure
Sewn, i.e. stiches in his arm.
rtb··on One Twin Exercises, the Other Doesn’t
I look forward to your enlightening anecdote based debunking of other sayings, such as that time you made a great broth despite too many cooks, or that time a gathering didn't get merrier with more people.
rtb··on Inside the Tragic, Obsessive World of Video Game Addicts
Mainly because they are creative / productive, whereas gaming is passive / consuming.

rtb··on BBC uses RIPA terrorism laws to catch TV licence fee dodgers in Northern Ireland
Nice find. That site explains the situation clearly: the vans exist, but don't do any "detecting". Instead they spend their time parking them in prominent places to perpetuate this myth. http://www.bbctvlicence.com/Detector%20vans.htm
rtb··on BBC uses RIPA terrorism laws to catch TV licence fee dodgers in Northern Ireland
They do "exist", in the literal sense of the word. You can see a picture of one on the wikipedia page about it. http://en.wikipedia.org/wiki/Television_licensing_in_the_Uni...

However, they have never been used for enforcing TV licensing. They are entirely a publicity stunt / a myth put about by the BBC to scare people into buying a license.

"Detector vans" are a myth.

There is no reliable evidence that they exist. The BBC likes to perpetuate this myth for obvious reasons.

EDIT: sorry, I mean there is no reliable evidence that they are actually used for enforcement. Several vans do exist that were used in TV advertising to start this myth. Whether they worked or not is very debatable. (Certainly their supposed detection mechanism wouldn't work with LCD TVs, now more common than CRT TVs.)

rtb··on Schlieren Optics – See small changes in the index of refraction in air
Interesting. I don't think that would be possible - the technique shown here relies on a mirror to get interferometry between the two light paths. I can't see how interferometry would be available to soaring birds (between its two eyes, perhaps?). Although nature has come up with some very surprising and impressive inventions before, so I might be wrong.

I would guess they're just very good at spotting the conditions which lead to thermals.

EDIT: of course, you can directly see thermals via the shimmering / "mirage" effect. It's normally obscured by the background noise, but maybe soaring birds are attuned to that. That's much more plausible, but a different effect to that shown here.

rtb··on Nicholas Carr’s 'Glass Cage': Automation Will Hurt Society in Long Run
The point is that "unintended consequences" are much more likely with complex systems. When you wield an axe, the consequences are fairly direct. When you leave home for the 101st time after buying a Roomba, you are still responsible for the consequences, but they are much harder to keep track of.
rtb··on C# Autocomplete Demo Using Bing Code Search Engine
Permission to "view and fork" is not the same as permission to copy and paste into a proprietary software product (i.e. this may not be legit for use by "enterprise" developers)
rtb··on Why Dyson's robot vacuum took 16 years, and why it's headed to Japan first
People are listening, but they disagree with you. The build quality is good as well as the performance. It is made of plastic because that is tough and soft (see previous comments about banging into things). You seem to be saying it should be made of metal and glass because plastic is "cheap", but that would be a worse vacuum.
rtb··on Why a Dead Alkaline Battery Bounces [video]
For some reason, it upsets me that he refers to spent / empty / used batteries as "bad", as if they were faulty.
rtb··on A girl with three biological parents
It seems like you are asking why eugenics has been rejected as unethical. If so, Wikipedia has some starting info: http://en.wikipedia.org/wiki/Eugenics#Ethics

rtb··on Some Dark Patterns Now Illegal in UK
Sorry, you're right -- RyanAir's headline price is actually achievable these days (if you manage to get past all the Dark UX practices, some of which were called out as examples in the OP). I was thinking of a few years ago, before the EU had to pass a law specifically banning their advertising practices, much like the law currently under discussion.

In my experience, EasyJet do offer you lots of low value "extras", but they do not try to trick you into taking them in the same way as RyanAir do (did?).

So I stand by my example, although perhaps it's not the best one available :-)

rtb··on Some Dark Patterns Now Illegal in UK
> I meant why there are no companies with marketing messages that would amount to "we're not going to fuck you over like the Other Company We Can't Name".

Probably because they can't name them in the ads, which would make the message rather confusing :-)

rtb··on Some Dark Patterns Now Illegal in UK
Huh? There are loads. I can think of several companies that I buy things from because I know I won't get messed with even if the headline price might appear a little higher than their competitors (think EasyJet v.s. RyanAir).
rtb··on The US Intelligence Community has a Third Leaker
> Again, PRISM isn't mass surveillance (as it needs specific selectors)

I don't agree with this assertion.

If recording as much as possible that everyone does via a computer is not mass surveillance, then what would be? That is what is happening, and it is mass surveillance.

Why is mass surveillance bad? Because of the chilling effect it has on freedom of speech and freedom of association. These things still apply even when the government promises not to read the data until you come to their attention. So even if you deny the term "mass surveillance", then this conditional surveillance is bad for all the same reasons.

Yes. There is no other way to get all three cases correct.

(If this is a burden on your users, you should consider ways to drop this requirement.)

"at Scale"? oh the irony
rtb··on Is Bitcoin the Future of Money?
Betteridge's law of headlines would seem to apply.
rtb··on Greed and the Wright Brothers
James Watt also spent much of his time and energy fighting patent battles in a hope to prevent others from entering the market. Who knows what further innovations he could have pursued if he hadn't been derailed by that greed. It looks like this is a recurring problem.
rtb··on Has StackOverflow saved billions of dollars in programmer productivity?
It is both!

In search results it is an information-dense bible of programming knowledge.

If you click on the feed of newly asked questions, it is filled to the brim with idiots with barely any understanding of programming whatsoever.

The magic of their voting system and google's search algorithms converts the latter into the former.

rtb··on Jakarta recalls ambassador to Australia over spying claims [video]
> Quite frankly, I'd much rather professional diplomats play these sorts of games, and we get to live in relative peace, than the outright carnage, war and bloodshet that characterised the thousands of years before this.

Huh? So the causal difference between the peace we now enjoy and the carnage the world used to endure is that there is now more spying?

The scam is that they are skilled at not paying out when you need them.
