Because, due to the limited precision available to floating points, they are not precise.

Example, given floats a, b, and c

c = a - b

might result in

c == a

There are volumes of literature related to this.

The short explanation why it is so, is that there is an infinite range of numbers, but we do not have infinite amount of memory, Therefore, to perform operations on very large (or very small) numbers efficiently (on current computer architecture) you need to round things around.

If you do not have time for a degree in maths, then at least go and read this before operating on any instructions on floating point in production code, thanks:

> ... but it seems curious that this event wouldn't have affected all living creatures universally.

That's easy to explain based on the fact that some species tolerate temperature change better than others. Remember that the Toba event took place just as an Ice Age was beginning, so there were multiple stressors, affecting many species. The survivors were those that (a) could take shelter against the sudden cold, and/or (b) were naturally more resistant to the cold.

A similar partition happened during the asteroid-initiated dinosaur extinction event 65 million years ago -- some species were better able to deal with the sudden cooling of the global climate. Like the little mammals, who could take shelter underground, and from which we eventually sprang.

> Would plants and aquatic species expess such a bottleneck differently ...

Yes. Some of them are able to tolerate freezing conditions that would kill most land animals. As just one example, there are species of frog that can freeze solid, then recover when things thaw out.

"Europe hasn't even moved over to automatic transmission yet"

After having a couple of cars with automatic gearboxes (including a 4.4L BMW - so lack of power wasn't the problem) I find that I am much happier with a manual gearbox.

NB I'm not resistant to new technology in cars - my current car has automatic parking and I use it a lot and normally leave the lights on auto as well.

That's because automatic transmission is the worst and invented by the devil.

More seriously, using an automatic transmission results in trade-offs, for instance fuel usage was the historical number 1 sticking point with automatics guzzling up the petrol compared to manuals. Modern engineering has closed that gap but there are still issues related to control - ironically a move to fully autonomous cars would solve most of them (principally in non-autonomous cars drivers in manual transmission cars can use knowledge of future road conditions to make gear selection decisions that an automatic transmission cannot make as they have only a limited input set)

As I understand it current self driving car technology fails whenever the situation becomes sufficiently complex (eg. icy/wet roads, some other unexpected traffic situation) and require the driver to take control at this point.

At what point, given normal business conditions, would you need to hold 100% of deposits? You only need enough to cover withdrawals; ignoring the MtGox issues 60% seems quite reasonable.

The only time you'd need to worry about 100% is if you're anticipating a total run on deposits or you're going to close the bank.

I've been saying this for years. Most of the tox studies or efficacy studies in mice have poor or no models that correlate with human biology. They are indicative at best but should never be used to give a black or white story. The pharma industry and academia is throwing every single year dozens of potentially active molecules because they see toxicity in animals. Note that animals models have also permeated the regulatory bodies, therefore making it into de facto requirements to develop drugs. And it is so rarely ever contested on scientific grounds, where the Science part is effectively very thin.
13/16 still isn't perfect. There is something like an extra quarter beat every measure, as in 13.25/16. Of course, that makes it closer to 13/16 than 7/8.

You're putting up a strawman. Information for the sake of information is not knowledge, nor learning. One can spend their whole life watching reality TV and name every single celebrities in existence - hardly anyone would call that act "learning" or "acquiring knowledge".

Of course if one could still be learning in a suboptimal way: acquiring useless information, or acquiring information without understanding of the subject matter, but that's an orthogonal issue altogether: it's suboptimal regardless of your effort/time/how much knowledge you had.

At the very least, I found it hard to believe that in this time and age, one can acquire enough knowledge of any subject (breath or depth) that any more effort would be suboptimal. The other choice of thinking "I know enough and don't need to care anymore" is potentially far far more dangerous.

Not committed to humans as they are in 2014 sticking around forever. I think any disagreement between these views rests mainly on what we mean when we say extinction event. I would insist, however, that the notion of human consciousness being a phenomenon worth preserving as long as possible isn't some 'New Age fantasy', come on now.

Right, if there's a flaw in the study, it's in the representativeness, not the sample size.
Or (probably more Apple-like approach) make it stand-alone and interact well with iPhones and leave it open to Android support later on or maybe start by offering the kind of support for android other mid-high end systems offer.

So the thing is usable without a phone: GPS, music, etc. You can answer calls for any bluetooth enabled phone. Advanced functionality like siri would only work with an iPhone.

This is a new market with new use-cases. Starting by making the basics work well is a good starting point.

I think that what iPhone (and Android shortly after) did for phones can be done for a bunch of things, including conventional PCs. Apple is uniquely capable of targeting the high end but they are not the only ones capable here. They'll need to execute very well.
> Karpeles wrote his own SSH server in PHP.

I never heard of that one, although I know Mark Karpeles is the author of a few tools in PHP. I met him around 2003 when he developed, hosted and managed a Ragnarok Online (not so) private server (fRO) on Linux (hence his surname, MagicalTux). The whole time he paid the hosting himself. Contrary to more known servers such as eAthena, this server had a unique feature is that it was written in PHP and developed mostly by himself. The server was stable, allowed for quick iteration and took the load quite fine. The whole time he paid the hosting himself. He also wrote an inetd daemon in PHP. Another PHP game project that never took of was 'Inochi', but I can't remember what it was about. He started a few other projects such as a homegrown OS and a VoIP system/company.

Still I can't tell much about the quality of his code since I never read it, and all traces of his code have vanished, and that's been more than 10 years ago. What I can remember though is that he was smart and friendly, but very sloppy at communicating.

For a side story, fRO grew sufficiently big that it caught attention of Gravity and Mark received a cease and desist letter, which he obeyed short of facing a trial. He rebuilt the server soon after though, authorising only a select few members (of which I was one) resulting in something more like a permanent, albeit remote, LAN party, and finally abandoned the project, stepping down and transitioning the management to the player community. The community stayed strong enough even without access to the server that Gravity offered an exit in a form of an officially sanctioned, monthly-paid server. That server was eventually integrated into the official Gravity managed euRO.
"virtualized"? I'd rather call it "mirroring".
I think your gut-check here will turn out to be inaccurate. We will have self-driving cars, and they will come soon. Ultimately, you need:

1. Cars capable of making decisions real-time, on the road, given unpredictable stimuli
2. A network of things, between the cars on the road, to allow optimization and homogeneity of traffic
3. Regulatory environments permissive of autonomous vehicles.

All of this is well under way and I'd say conservatively we'll see robust networks in less than a decade.
There is no auto manufacturer, or manufacturer of any kind, really, that is in a position to push Apple.
> going at speeds the human brain has never evolved to appropriately deal with.

Not to discuss your other points, but who are you to say the human brain has evolved or not to deal with X or Y ? The human brain is actually very capable of dealing with multiple sensory signals, and the fact that most people can drive cars on motorways without crashing in each other's every 2 seconds suggest that the human brain is perfectly up to the task.
I used to think automatics were horrible (I live in the UK, drove manual for 15 years) then I got one...

In terms of fuel economy, isn't it just a matter of time before automatics become as economical (then probably more economical) than manuals? Even without anticipating future events? Driving efficiently feels like something a computer could optimise for and that a human has no natural advantage doing.
I personally just love driving a manual car. Its not for any practical reason, I just get a kick out of shifting perfectly, the feel of the engine and the control that I have.

That said, if there's a self driving car, you bet Id rather use that.
I'm not exactly opposed to all legislation on price. I do think that unapproved credit card charges constitute fraud, but in-app purchases (as far as I have experienced them on Android and iOS) do not work this way. They all require explicit confirmation, after the "free" install.

So a better analogy would be a theme park with free entry (or some constant entry price) that then offers optional "in-park purchases" like food, special events, or expedited roller coaster lines. I wouldn't consider this fraud, but for non-free theme parks, I do think a court might eventually have to make a decision based on what exactly you're agreeing on when you pay for a ticket. To avoid legal ambiguity, I suspect theme parks could simply have a document describing what services are included with the base ticket (though not necessarily listing all optional services which cost extra).

>> Evolution is not a plan with a goal, it is a blind algorithm that chooses survivors, regardless of the survivors' traits, with the single requirement that they are the fittest for the environment in which they find themselves.

> Well that does sound like a goal driven algorithm to me.

Not in the way most people mean. When people hear there's a scheme to evolution, many assume this means a gradual ascent in complexity or intelligence, but that's not necessarily so. There's no relationship between natural selection and any specific endpoint.

> Evolution is an optimization algorithm ...

No, it's an adaptation algorithm. Its outcome are never optimal, only the best approximate response to environmental changes, in an ever-changing environment.

I had a little peak and started seeing a few bugs but then I hit line 1009:

> mail('mark@ookoo.org', 'BLOCK IMPORT ERROR', $e->getMessage()."\n\n".$e);

I haven't done much digging around this issue (so perhaps someone can enlighten me on this) but I was curious at what was at that domain (since it seemed the email was going to Mark Karpeles). When I went to the staff page[1] I could see his company Mutum Sigillum LLC takes care of the administration for that IRC network. That same staff page used his nickname MagicalTux and the corresponding page[2] links to his "Professionnal PHP5 certification"[3] but that lists his name as "Robert Karpeles" and not Mark Karpeles. Does anyone know why this is? Did he change his name between 2006 and now?

Based on this:

Emmy was the ship's cat on the RMS Empress of Ireland.
She was an orange tabby cat who never missed a voyage.
However, on May 28, 1914, Emmy tried to escape the ship.
The crew could not coax her aboard and the Empress left
without her. She was reportedly last seen on the roof of
the shed at Pier 27, watching her ship sail out of Quebec
City.[citation needed] Early the next morning the Empress
collided with the SS Storstad while steaming through fog at
the mouth of the St. Lawrence river and rapidly sank,
killing over 1,000 people.

I have decided to disembark any ship when the cat leaves.

I still don't understand where you're going with this. Just because it's not capable of entirely providing our current power consumption doesn't mean it's a bad idea for deployment. After all, our current majority power source is a finite resource that's going to run out, and similar resourcing issues apply to uranium.

You're probably going to reccomend Thorium, but the barriers to commercialisation there are more serious.

Personally I suspect we'll end up with 30% solar, 30% wind, 40% other (tidal, nuclear, geothermal, biomass etc).
> I mean, Europe hasn't even moved over to automatic transmission yet.

Haha. 1) Driving automatic cars is so boring. 2) it makes your body unbalanced constantly since you use a single foot, therefore your back will ache over long periods of driving. 3) You cannot adjust your speed as fast with an automatic car, we are stuck with binary controls while manual cars provide all the flexibility you need in real, and critical driving situations. All serious cars (like sports cars) are by far usually manual.
Does Bluetooth have the necessary throughput to send 1-3 MP of graphics data with approx. 10+ FPS to a car LCD display? Even if this was possible, it would drain your phone's battery considerably, which means you have to plug in your phone nevertheless to let it charge. Aside, attaching the iPhone via cable will be straight and much less cumbersome and error prone than pairing over Bluetooth.
As others have said already, switching jobs (even to a more cozy/corporate position) is demanding in itself. So it may well be harder on you than just staying in your current role. You also have to consider that if you step down, the company will have to replace you, and that may not be that easy. Maybe the company is actually better off keeping you at low intensity (for a while), rather than replacing you.

That all said, yes of course it's doable - But it takes compromises on all sides. I had my first child three years ago and I accepted a position as CTO in a VC-backed startup at the same time (I started 14 days after he was born). That was pretty tough, but it worked out. I could not have done it without family support, my wife in particular who stayed at home for a while, and with a good understanding from the investors (I knew some of them from previous work, so I assume they were confident that I was right for the job). Whatever you do, make sure you align expectations with your co-founders and with your wife.

Good luck with it all.
