Not from what I'm seeing. No one is planning to cancel their reservation. I wouldn't, if I had one.
I only have about an 80% success rate with Touch ID anyway. It doesn't seem to like sweaty fingers. Every so often I get unlucky five times in a row and have to unlock it with my password. Who's to say it didn't happen by accident? Or is having sweaty fingers going to effectively be an imprisonable offense now, the way forgetting your password is in jurisdictions where you can be compelled to reveal your password?
To create innovative solutions you have to be creative. This includes thinking outside of the box, putting dogma into question, clearing your own paths, and this all translates to connecting concepts that we don't usually connect. Some people do it naturally, some use psychedelics, some do both.

I think cultivating this as an attitude is usually a good thing (in life) and can lead to powerful insights. In fact this is a really cheap way to innovate. Take concepts from one domain, cast them onto another, profit. A cross disciplinary culture helps a lot. I'm sure many people here understand very well what I mean.

So to answer you more precisely, I really have only one data-point and I think both the traits you describe and psychedelics can make interesting (if not better) engineers.
True. But it is almost pointless to compare these two programs since Apollo was so much more complex.

To put it in perspective, Apollo flew on a rocket with five engines producing 1,500,000 lbf thrust each, on the first stage alone. By contrast, the Virgin motor produces 60,000 lbf thrust for 70 seconds.

The Apollo program had a safety culture configured so that if anyone identified a safety issue, they became responsible for the problem and responsible to sign off that it was corrected.

this comment is a bit OT.

Does memory really bottleneck instruction throughput though? I've never ever seen code that stalled on an instruction fetch.

CPUs generally hide latency by auto-prefetching the instruction stream into cache, and memory bandwidth has been keeping up just fine with CPU speed. Hence memory latency rarely hinders instruction throughput, unless your code jumps around unpredictably every few instructions (most doesn't; the only common class of program I can think of which does are emulators/interpreters).

Probably the only differences in ISA design/implementation between this universe and one where memory latency tracked CPU speed would be that (a) instructions would need not be prefetched into cache (possibly there'd be no cache), and (b) we'd still have wacky instructions like the TMS9900's X instruction, which executes the instruction at a given memory address.

Quandl for now, but fairly soon I'll be collecting realtime prices from interactive brokers.

(My strategies generally run on a daily basis, so daily data is good enough for that. But soon I'm going to switch to a full algo strategy, which will require realtime data to backtest.)
It's also possible to install the seed for the TOPT generator on multiple devices - all the ones I've bumped into have a mechanism for typing in a long-ish string as well as scanning a QR code - record that string (secured like a password, in something like 1Password) and you can always re-seed another device to come up with the same codes. I've got all mine on two phones and a iPad - one of the phones is usually in my pocket, the other is almost always at home.

As always, it's a security/convenience tradeoff - I've gone from needing "something I know and something I have" to "something I know and any one of several things I have".

Your tradeoffs there may vary - if I were a political-dissident/whistleblower/drug-czar I'd probably consider the risk of losing access altogether preferable to opening up additional avenues for vulnerabilities - an NSA-level adversary would probably have a significantly easier time if they knew they only needed to stealthily subvert one of several devices (at least one of which I don't usually have on my person) to get access to all my tfa secured assets, but the additional risk if I'm protecting myself from 4chan-grade griefers or non-network-pervasive internet criminals is - for me - low enough to accept for the additional reliability and convenience of multiple authorised tfa token generating devices.
Agree 100% with this article. I've done Perl, Java, and NodeJS applications. The absolute worst code I've ever seen was Java, which with OO and typing adherents say leads to maintainable code. Trouble is, most Java engineers are no better than Visual Basic programmers. Functional Perl and JavaScript are beautiful things. And by staying away from classes, you get to the more fundamental - data structures and transformations.

"Problems like these are almost always the result of management pushing things faster than the engineering progress warrants."

Coincidentally, we were talking about such an instance today at work, the Conestoga 1620. As relayed to me, the "low frequency noise" mentioned in the wikipedia post was a low frequency structural mode that was missed because management didn't want to pay for a high enough fidelity finite element analysis.

We went from not flying anything heavier than air to going to the Moon in 66 years. If we really really wanted to, we could go to Mars in thirty. This is a problem of priorities, not technologies (although the technological problems are real, they are not insurmountable).

> Was it safe? Well … for starters it is just an inaudible soundwave being transferred – as in the kind also used for women during pregnancy. It also happens to be how your car likely tells the distance to objects when you park or if you have a side assist whether you can change lanes safely. Check.

Both of those Examples involve short exposure. That doesn't necessarily mean long exposure is OK. You would not, I hope, conclude for instance that an X-Ray based system is safe because dentists X-Ray people as part of an annual check up.

I expect it to turn out safe, but I'd want to see some studies first.

Also, I'd like to see studies on what affect it has on pets. Will it also be inaudible to dogs? If not, that needs to be documented so that dog owners won't unknowing torture their pets.
Then use v5 UUIDs. Or /dev/urandom, which seeds a PRNG with hardware-sourced randomness.
Presumably the poster is the author so - some feedback:

Nice layout & smooth look but the wording requires some work. Its full of defensive/indecisive phrases like:

"So, I thought I’d"

Look at that phrase carefully and consider what value you're adding there. Zero. You're just conveying a sense of uncertainty, timidity and defensiveness. The entire article has that vibe.

Still - its not bad. You get shtty problems and then you get problems where someone just need to point them out to you so that you can fix it. This is the later.
I think this is one case where the law is largely following many people's desires, at least in the USA. I used to live in a city with no zoning (Houston), and yet it was exactly the same thing: no retail or commercial anywhere near the residential area, and very low density. Why? Houstonians reinvented zoning via private-sector contract law. Since many people apparently want to live in residential-only neighborhoods—or at least have fears of what kind of noise/crime/etc. might happen if the alternative were allowed—developers cater to that by putting "residential-only" deed restrictions on new developments, so there are large tracts of land where it's prohibited to use the land for commercial activity. Usually higher-density redevelopment, or even subdividing/subletting, are also prohibited by the contracts.
UUIDs have the advantage that no coordination is required. With a database you will create coordination problems as you scale up your system.

I have either a high or total assurance that any UUID I self-assign has never been used anywhere, ever, for anything else, by anyone else, in any system.

In fact, the odds that I will have a collision with another UUID are lower than a cosmic ray striking a computer at the moment when it is performing the uniqueness check.
Some people are susceptible for psychosis. LSD might give them the final push, turning them from the normal looking guy that sometimes say weird things to full-blown crazy.

I also know about a similar case in my social circle. An offbeat guy starts seeing demons after his first trip. Recovering in a mental institution ever since.

Yet I don't think LSD is to blame, it is just a trigger for a pre-existing underlying issue.
This may be a bit naive but are UUIDV4 completely random from 'head-to-tail'? I mean, given the birthday paradox calculation, couldn't you just take head of the uuidv4 (i.e.: the first x characters) to arrive at the collision/space-consumption tradeoff you want?

In the US context, boundaries matter because there is a steep density gradient from center to suburb. There is a technique called weighted perceived density to fix the difference and make cities comparable. [0,1]

Tokyo, Osaka, Mexico City, Seoul, and (to a lesser extent) Paris don't have steep gradients of density from center to edge and have better defined natural boundaries between urban and rural.

The blending in the USA edge cities is the result of heroic subsidy levels and Stalinist command and control zoning and minimum free parking mandate policies. It is not natural or compatible with free markets.

The areas I quoted in the USA (NY County, NY and SF County, CA) are very specific and not at all fuzzy.

For those wondering about if it would be audible and if the technology would impact pets, here's the receiver's patent application:

http://www.google.com/patents/US20120299541

The frequency range they list in examples for applications are from 40kHz to 110kHz. This actually does overlap with the hearing ranges of dogs and cats somewhat. Wiki lists the dog hearing range from 40Hz to 60kHz and the cat range from 55Hz to 79kHz.

Humans should be safe though since a common number for the high-end of human hearing is 20kHz.
three-fiddy it is! (Umur from Citus here)

I hear you, and we are working on fixing that even as it might take some time. The challenge for us is that for an enterprise, alternatives could cost literally in the millions (see Oracle pricing at $100k's for just a single 8-core commodity machine). For start-ups, we have offered Citus for prices lower than $5k per node in the past, and we provide an entirely free community version as well.

Essentially, our take is to not have pricing be what stops you from using CitusDB. And if you are an enterprise, the value you get from using Citus should far exceed that you'd get from any other alternative out there.
The back story of this company is intriguing. The founders presented a prototype way back in 2011 at the D9 conference[1], and apparently weren't able to get any traction until they found a believer in Scott Nolan at Founders Fund[2]. Interestingly, Nolan seemed most impressed by the company's distribution plans:

> Mr. Nolan said Ms. Perry had shown that chain stores and some “quick-service restaurants” were eager to integrate a wireless charger into their plans. She “had addressed all these key risks and got them nailed down early,” he said.

To me, it's not surprising that folks would be excited by the concept of wireless charging, just as you could easily find plenty of people who would tell you they'd buy a Back to the Future-style hover board if you could actually build it.

The big question is whether the technology is real and commercially viable. One physicist who has worked on wireless charging applications says he reviewed uBeam's patent applications and ran the numbers. His conclusion: it isn't[3].

Who is correct?

Tangent: I think it's safe to say that HN -- on this thread in particular -- is populated by many people who are deeply interested in space travel.

I'd like to recommend everyone select as their next book for pleasure reading Andy Weir's "The Martian".

Here's my GoodReads review:

It's not high-brow literature by any stretch. But it's not about the writing per se, it's about the story. I challenge anyone to read it without caring what happens to the protagonist. I recognize that he (and perhaps by extension the author?) may be borderline juvenile on a few occasions... but for me it hardly detracted from the reading experience. On the contrary, I was sufficiently immersed in being on Mars in the shoes of this bold and lonely astronaut that the book per se disappeared nearly the entire time I read it. Pausing to re-read a noteworthy turn of phrase or analyzing it as literature might well have detracted from the author's intent. The story is the thing. For me, the writing got out of the way. And I'm glad it did. This is an extremely well-researched, gripping, exciting page-turner. If you are remotely interested in space travel, imho it's a must-read.

As some others have mentioned, I think smartphones are helping to solve this as they get more common and the transit planning gets fast/good. But another way is just to have stable and frequent service, instead of trying to microoptimize different on-peak/off-peak/night or weekday/weekend schedules. That way people just learn that this is the service, and it always runs, problem solved.

Copenhagen has mostly converged on that: the metro, trains, and trunk bus routes now mostly run 24/7, with the same route all the time, and high enough frequency that you don't have to worry about when they'll come and how to time connections (typically 2-7 minute headways during the day, 15-20 minutes at night, 30 at night for some buses). Works well, though of course it isn't cheap to operate such a level of service. I definitely find it easier to take night buses now in particular, as they've been moving more of them to this schedule. It's something I do only occasionally so I'd never remember what the "N" night-bus routes were, but now it's easy, because the answer is that it's just the same "A" bus routes as always, not special night buses.
If it were me, I'd ditch the two letter handle, and with it the bother.

People need to be much more aware of the fact that you don't own your gmail address, or your Twitter/Facebook/LinkedIn/Instagram/whatever account. Those companies encourage people to build their reputations and networks and "personal brands" inside their walled gardens, while repeatedly demonstrating that they won't lift a finger to help protect the user's custodianship of "their" usernames.

Unfortunately - when you explain this to people there's no really good answer to their immediate "so what should I do?" question.

I no more "own" the bigiain.com domain than I own "bigiain" on HN, or "bigiain@gmail.com". While I can ensure I keep paying for it's registration, I have no doubt that if Monsanto or Goldman Sachs or Apple launched an new thing and trademarked it "Bigiain", my registrar would fold instantly to a legal demand from their lawyers, and I'd be just as out-in-the-cold as all those people without friends-of-friends in high enough places at Instafacetwigoo to "fix things", or with publicity platforms like @mat behind them.

I think Singapore honestly remains as a serious anomaly to political science. Defacto one party government with extremely illiberal policies and yet the people are happier, more educated and more well off than many other countries that have liberal democracies. What's further more surprising is that it remains very multiethnic and yet the people get along with others just fine unlike other parts of the world.

"Taj Mahal found it distressing when his audience clapped wrong because it felt like a failure to emotionally connect with them."

How do they know this? Did they ask him or is this their assumption based on their expectations. It is annoying enough when researchers impute motive and thought to inanimate things. But people actually have them so it is all the more frustrating if they are assuming they know what he's feeling.

The beat you emphasize has a great effect on the feel of the rhythm. Instead of "feeling like he failed to connect on emotionally," it could just be that he wanted them to hear the song as he intended to play it and without altering it's rhythmic nature.

the waiting for prices to go up is a consequence of zoning laws. There's pretty much a fixed supply of housing in Paris and a rising population, so people just sit on it.

The population point isn't super relevant because people are still moving into Tokyo (for work or school mainly), so Tokyo's actually growing _faster_ than Paris is (http://www.wolframalpha.com/input/?i=population+of+Tokyo+ove...)

The big difference being that almost nowhere in the Tokyo metropolitan area has low-density buildings (compared to people in nicer suburbs on the outskirts of paris with huge housing.)

The fact that there are so many old buildings in Paris is also a consequence of making things hard to build in Paris. There's more than enough demand to make obscene amounts of money with a decent sized apartment complex in downtown Paris (if you could build it). It's not like Tokyo is falling over every 10 years to earthquakes.

One thing is that houses in some Tokyo suburbs are built like crap, so old houses are falling apart (not building many houses out of stone). I think more recent housing is built more sturdily (not sure though)

Anyways, the comparaison is fair, because the prime difference is what we're talking about : Zoning laws. There is nothing magical about Paris which makes it impossible to use the same techniques to solve this problem.
I mostly grew up in American suburbs, and my conclusion from that is that many people really do seem to like that lifestyle. Not everyone; some people who live in residential-only, car-oriented neighborhoods would rather not, but have various constraints keeping them there. But quite a few people moved there on purpose and like it.
