How tiny? If you need a decent salary it may be harder to find a startup that is still very small.
Unfortunately, it would be relatively easy for anyone to find that transaction, even if he didn't want to disclose it. Don't look for Satoshi's wallet, look for the shopper's.

I'd pay for some cool extra modes like darkroom. Or is there a decent program that does that already?
You can never hope to discover the truth behind the fiction of Satoshi. The closer you think you get, the further fiction will hide the truth. Indisputable evidence is nice, sure - but knowing is not being[0].

The man is a legend for a reason and will remain that way, regardless of anyone who claims or is proven to be, or not be him.

If the test is below the level of education students were receiving before the test, it can not possibly increase the level of knowledge. In fact, the schools spend an enormous amount of time not only administering the tests, but also preparing specifically for the test, when they should be educating the children.

The California tests have expanded from something required every 3 or 4 years (I think I took them twice, but I opted out in high school) to something required every year starting in second grade. They also expanded in terms of the length of the tests. California does have specific programs for children from homes in which English is not spoken or is a second language.

I spent 10 years in Virginia and sent my daughter to public school for ~2 years there. During that time, I noticed a trend in the way that state used the standardized testing and recommendations of "No child left behind". They closed schools that either did not meet the average on the tests (umm... what's an average again?) or could not increase their scores year after year. After a few years of this, two themes started recurring:
- close an under-performing school, bus the kids further to other schools which are now more crowded and trying to improve the performance of the students that were not doing well enough to keep their previous school open
- good schools started having trouble increasing their scores in subsequent years

When it was an under-performing school that closed, very few people other than the parents of children at those schools (and maybe the surrounding schools) had a problem with it. When the best schools in the state (at least according to the test scores) started to fail the requirements (how do you improve test scores every year?), it still took a while for people to realize that the law (whether accidentally or otherwise) was going to close the doors of every public school in the state.

That's what it is. You have a unified interface for generating things, and you need to have deterministic test to make sure your thing is being generated correctly and the data generates the thing fully and correctly.
One thing is for certain, if Dorian is the real Satoshi, the Feds - NSA and FBI - are all over him, and they will know for certain whether he is the Satoshi (if they didn't know a long time ago). If Dorian = Satoshi, he's going to be forced in front of the NSA, and interrogated about bitcoin, he will have no choice in the matter (it won't matter if he's no longer involved, and it won't matter if there are no weaknesses to give the Feds, they will still do it).
Yup. I'm using a Das Keyboard, and can only get six keys at a time on their applet. One way some people get around this is by using PS/2.
Sounds like the government propaganda that frequents most of the news channels worldwide
Also, for pair programming it gives the pair a common goal to aim towards. The people know the inputs, and outputs up front. So one person doesn't just stare into space whilst the other person codes the function, and then says "this is what I wanted it to do".

It also helps reduce code, since you only write code to pass tests. You do not write code for some general theoretical use case that is never required.

Here's the presentation. It's a pretty fantastic watch that shows what just a few small design decisions can do for a product's impressions on an audience.
I didn't mean to imply anything illicit concerning Satoshi. I meant that those that would be interested in the stash could be the silk road types or worse. I find it curious that Dorian/Satoshi are not spending the money. Why not? Imagine having $1 billion and not being able to touch it.

I am always amazed that keyboards still do this. We have scanning matrices because back when I was a new engineer pins on a microprocessor were both expensive (larger packages) and they required more gates in the CPU (more expensive CPU) or chip doing the scanning. Today transistors are free and surface mount BGA packages can put down a lot of pads pretty simply[1]. So your typical 104 key keyboard could actually have 104 actual wires that the CPU scanned. And even if you don't want to put down a 144 ball BGA (that is only 12 balls by 12 balls, logic is fast enough that you could connect all of the keys to a bunch of serial shift registers, and scan a complete bitstream of all keys 1000 times a second. Easily matching the reaction times of humans.

So where is that keyboard?

Just to be crisp here, an STM32F429 can have 135 digital I/Os in the 208 quad flat pack. It also has a megabyte of flash and 192K of RAM. It also has a USB Phy built right in so you can just wire it up to a USB connector. Its $8 in 1K quantities in that package. So parts : chip, PC board, 120 or so switches and plastic case and key caps. Sure its more expensive than the $0.75 AVR chip they currently use but we're talking high end keyboards here.

As you can see it's pretty fluid right now! Would love to hear ideas.
true, but still outrageous
You're conflating success with intelligence. It is undeniable that Nowell, Torvalds, and Wozniak are all very successful people, what is unclear is how intelligent they are or if their success is primary due to their intelligence.

There's an awful lot of very intelligent people who never did anything with their life, and conversely there are a lot of perfectly average people who have done ground breaking things.
> To be fair, there are many reasons why North Korea was left alone while Iraq was considered "safer" to invade.

Many reasons why Iraq was considered more important to invaded, and all of those reasons are "barrels of oil", as elucidated in 2003 by then-Deputy Secretary of Defense Paul Wolfowitz: "Look, the primarily [sic] difference -- to put it a little too simply -- between North Korea and Iraq is that we had virtually no economic options with Iraq because the country floats on a sea of oil."

I generally just assume a tenured professor (or associate professor) of anything can write papers that will get accepted in certain journals. Making any further assumptions about what they can or can't do has been proven to be well outside the realm of possibility. Clearly, though, this one can write an article that got some attention, which may be more useful than anything else they might have attempted.
I'd be interested to hear what options he has too.
$15,000-20,000 a year. They don't go to private school either. It's only marginally better option than the government schools.
My sense is that one should make the unit tests to be as resilient as possible to refactoring and changes. This means that for so long as the public behavior of the class does not change, one should not need to do much if any updates to the tests.

Thus any test that is written in such a way that it would be present an issue in refactoring code should be avoided if at all possible. A simple example is directly constructing the class under test in the test method:

@Test
public void tryToAvoidDoingThis() {
MyClass = new MyClass(param1, param2);
// do stuff to my class
}

If this is done for each test method, when the constructor parameters change, e.g. a new one is added, then each of the constructors calls in the test method(s) will have to be updated.

Instead, have a level of indirection and have a single method that can create a sample MyClass. Now when the parameters change, only one construction site has to be updated.

In general, unit tests should not be testing specific / internal implementation details of the class. Rather, the tests should verify the documented public behavior of the class.

It's so sad. Parrot was conceived to be Perl 6's VM. Then the authors of Parrot decided to focus on making it more general purpose/language-independent, spent time writing incomplete implementations of various languages like Javascript on it, and ultimately didn't support any language well.

Parrot became so hostile towards its original purpose that Rakudo had to break from it.

Incidentally, I don't know why Perl folks don't implement Perl 6 on top of PyPy, which is a high quality dynamic language VM that already exists, and offers a JIT compiler to boot.

Even if Dorian is lying about knowing what bitcoin is, I think it wouldn't be a proof of Dorian = Satoshi. He might be worried people would dig his personal life more if he acknowledges he knows what bitcoin is.
The Soviet Union manufactured that image for deterrence/intimidation/diverting-of-US-energy purposes.

The US military-industrial complex amplified it for pocket-lining purposes.
A fair point, but it's not how she's painting herself, and she makes no mention of what the next step is.
If Satoshi still has his ~$400m in bitcoins, he could also likely strike a great deal with someone like Andreessen Horowitz (the cash), maybe with coinbase (build it), to create a sort of bitcoin bank (at a discount to his holdings in exchange for the liquidity to exit). It would enable a rather unique liquidity tool, sort of like a central bank; the new entity could provide bitcoins to bitcoin service businesses on demand for a fee (eg if they're having a hard time getting bitcoins or for any reason really).
My blanket statement regarding the precious waste of time children are coerced into is not limited to government schools.

To elaborate, Cydia is an app store/package manager for jailbroken iOS devices. The US Copyright office and the Library of Congress have confirmed that jailbreaking your iPhone is not a violation of the DMCA, and it is very easy.

Evasi0n7[1] runs as an application on your PC or Mac with your device connected, jailbreaks the device and installs Cydia. It does not affect anything in the regular Apple App Store, it merely lets you install additional programs including tweaks that customize the interface. Perhaps interesting, f.lux is featured on the front page of Cydia, so you don't even have to search for it.

The point isn't that it puts you to sleep like a drug. The point is you are ready to sleep; you don't spend forever falling asleep, that sort of thing. So setting a reasonable sleep schedule is still up to you.
interesting that you value this testimony so highly, because my weighting of probabilities for 'can a random woman in brooklyn definitively and uniquely identify an elderly japanese man among a line up of elderly japanese men based on a single interaction three years ago' comes down quite heavily on 'no'.
Fwiw....I love your interface and simple pricing. However, IPv6 is a deal breaker so I left. I understand things get busy... the problem isn't that ipv6 isn't available, it's that you didn't/don't communicate it. This makes me hesitant to become a customer again...
Because (and that's a quote) "PyPy is unproven and experimental technology".

If the test is below the level of education students were receiving before the test, it can not possibly increase the level of knowledge.

If the students already know everything on the test, then there isn't much need for prep. Take maybe 1 day to explain the test mechanics, another 1-2 days to administer, and you've spent maybe 3 days/year on testing.

You still haven't answered the question. How do you "teach to the test" (real tests, not tests written by straw men) without increasing student knowledge?
again? it seems like we hear about this about as often as voyager leaving the solar system...
It's funny, this is exactly what I proposed at our company to make sure that tested code gets promoted. If the build fails, the dev loses points, and his next push requires a code review from another person who has more points.

This fell on deaf ears..
First, we're not in a courtroom with the witness under oath. Second, because we're not, we can't cross-examine the witness. Third, even if we could and her recollection is as you say, the balance of evidence would remain heavily tilted against Dorian == Satoshi. Sorry. :)
> there is a TU variant with swept wings, var geometry, and jet engines that replaced this plane that most Russian republics use

"Most Russian republics"? So, more than half of the 1?

And "Tu" is just an abbreviation for Tupolev, its not a particular plane of which there are variants. Saying a "TU variant" is like saying a Boeing variant.

And there are two different Tupolev strategic bombers that meet that general description (the Tu-22 and Tu-160), neither of which is a variant of the Bear.

Yeah well it's not like I love being fat. We all know fat is bad, and I wish I had less of it, but it's not like my adipose is going to go away by scaring it with more bad news about why it sucks to be fat. Once you're fat, not being fat anymore is a really hard problem, which is why fat people aren't really known for eventually being skinny some day again, but there's a high prevalence of skinny people who once were fat eventually getting fat again. I've been fighting my weight for near a decade now, and I used to be a pretty athletic individual in my 20's.

I don't think skinny people understand. Maintaining weight feels like starvation to fat people, for at least some of them, like me. If you only eat enough food to just maintain your weight it hurts just as much as dieting. That will probably never change for us, even if we lose a lot of weight (and I have lost a lot of weight). So fat people have to be on painful diets the rest of their lives, just to not get fatter.

So my advice to young people is, don't get fat. If you're already fat, you're pretty much fucked.
I'm developing a notification service that lets people sign up to be notified when something they are interested in occurs, and most importantly only when that occurs. The goal is to be agnostic and let people be notified any way they like (email, app notification, SMS, phone call, letter in the post box etc) and for developers to be able to send notifications for a wide range of specific events (e.g. tickets on sale for this band in this city) using an API in their language of choice.

A basic version of the website is up right now:

http://bullhorn.io

I'm really looking for feedback on what to work on next. Is this a service that you could use in your company? If not, what's missing?

The next directions I'm looking at are:

0. Improving the look of the website.

1. Adding API support starting with REST.

2. Adding more notification methods (e.g. SMS).

3. Adding ability to create multiple-fire notifications and parameter based notifications (e.g. notify me whenever the weather in TOWN is > TEMPERATURE).

4. Adding built-in notifications such as weather, stock, etc.

Comments welcome.

The first example is a little hacky in using one function as both keyup event handler and message receiver.

This and some other quirks together make things harder to understand. The idea seems really cool, but a clearer (even if not as fun to read) README would help. :)

If I were the maintainer, I'd reduce the amount of text (by moving extensive API docs somewhere else? cutting some of the stuff that is just-for-lulz?), and think of adding an overview—how coalesce fits among existing solutions. Yeah, dry and boring, but practical.
...lead them to opt into private schools (which, those same sponsors proposed, should be subsidized by public vouchers that redirect funds from the public schools)

Um, doesn't that make the formerly private schools part of the public education system? The government is still funding schools, after all. It sounds like their sponsors just want to rearrange the public education system a bit.

I do agree with you that private schools receiving taxpayer funds should be subject to the same testing requirements.
Turtles all the way down, right? The point being that ultimately you need to have processes other than automated tests to ensure code, product, and test quality. Otherwise you're just shifting the problem around. Bad tests can be just as hazardous as bad code, if not more so, since they can easily waste lots of development resources which could have been used more productively.
If you like laptop style chicklet keys (you may not), Microsoft's new sculpt ergonomic keyboard is pretty nice. I replaced my natural 4000 with it recently and found it much nicer on the mushiness scale. It's pleasantly clicky, but not cherry clicky.
It even fits in a bag much better due to the detached numeric keypad. The mouse seems a lot better than the one that came with the 4000, enough for me to overlook the lack of extra buttons compared to my logitech G500. My one gripe is the positioning of the period key seems just a little off, something that has taken a few months to get used to hitting without miskeying.

Edit: incidentally, this keyboard, despite being fairly new, only gets 5 or 6 keys on the rollover test at the top of the article
Here's an example from a couple of months back when I received too much traffic from HN on my wordpress install and it made the server explode: http://pandoralive.info/?p=2243

It went up to 133 simultaneous visitors and then... poof!

After that I installed a Cache plugin, and since then I've had a couple of articles hitting HN again and going over 200 simultaneous visits with the CPU remaining at low levels. So yeah, Wordpress can scale, with the right plugins :)
Really ? That's kind of low, though. I would have thought most blogs get at least a couple of hundred visits (and not bots) every day.
The thing is, if Satoshi Nakamoto actually is any kind of elderly Japanese man in Brooklyn, then it's probably this one. There's a lot of anecdotal evidence (like, for example, his name, his background, etc) that link it to him.

How likely is it that this ISN'T the Satoshi Nakamoto, just another dude with the same name who happened to be an early adopter of the same technology at time when it was very obscure?

Of course this all depends on her story being true or not. But I don't think it depends on how well she would distinguish this Nakamoto from another Nakamoto. If she's telling the truth, high likelihood it's actually him.
Hm, not really. I see what you mean, but that's the kind of thing you start thinking about in the shower or when you're stuck on the real problem and need a break. Even before that, it's been circulating in your subconscious and may just pop out whole. It's not evidence either way of their technical ability.
I opted my children out of flossing.

The dentist couldn't understand why I would do this. I told him it was my legal right, and a decision that my husband and I had thought through carefully...

Yeah, yeah. Silly comparison. However, I'm trying to make the point that testing, so long as it isn't the end-all motivation of all teaching efforts, serves a useful purpose and, while there are other possible methods of evaluation and feedback, testing is the backbone of most school systems at present. As such, teachers understandably fail to understand when parents opt their children out of tests. This might explain why those teachers and school officials had such difficulty making logical arguments in favor of it. To them, it was like opting those children out of flossing.

The author of this article does make the case that the school didn't argue very convincingly in favor of the tests, but neither did she make any form of convincing argument against the tests beyond stress. Arguably, learning that early and thorough preparation reduces stress is a tremendously important lesson for kids, even beyond what they're actually studying! Testing also teaches children to remain calm under pressure, and that random chance ("Oh, I won't study that. What are the odds it will be a question?") is a cruel mistress.

Yes, it is your legal right to opt your children out of both taking tests and flossing. Take a stand! Hooray for your legal rights!
It says they don't know that it applies to humans. It doesn't say they think it might. It just says they don't know if it does.
