Given a complex number a + bi, the square root of a^2 + b^2 is called the norm. The norm shouldn't be thought of as a measure of the "size" of a complex number, since complex numbers are not well-ordered. It makes little sense to say that 2 + 3i is equal to 3 + 2i.
Ask HN: Why doesn't Google get it?
Maybe I'm crazy, but why doesn't Google do something outlandish next time they try a social product? How about instead of opening it up to everyone and replicating 98.2% of the features the other products have they actually try doing something useful for once?

Here's a ridiculous idea. I'm not interested in creating 14 circles with 22 people in each one. I don't want to group video chat with these people. I don't want to IM with these people. I sure as heck don't want to share photos from Picasa of all places with these people. Stop taking other products that already do their job and do it well by bringing it all into one. If an entrepreneur pitched me this idea, I'd tell him to slow down. What problem is he solving for me with +? I have no clue. Sharing? Not a problem. Chatting? Not a problem. Video conferencing? Not a problem. Group sharing based on a common interest? Not a problem. Random news or information (sparks)? Not a problem.

Focus on a product that enhances my actual social network. My closes friends. Maybe that's limited to 5 circles with 10 friends each, maybe it's less. Maybe my friends from each circle belong in more than one circle. Maybe I want to share information with just a cross section of those circles.

I know that's a lot of maybes, but I just wish Google would stop replicating and combining services that are already out there.

End of rant. I'll try + again in a month when I'm proven wrong by all of my friends using it.
LightPeak/Thunderbolt is supposed to support copper or fiber cables with the same port and controller. Within the next few years, there should be much longer fiber versions of this cable, with the optical transceivers replacing these chips.
Honestly, I never get these posts about "where should I go to do X…?"

Seems like a funny thing to worry about when you're in the early stages of starting a business.

I've lived in both NY and (currently) Chicago for a number of years, but I'm from Kansas City. When I go back to Kansas City I see two things:

1. People doing amazing work.
2. People making excuses for why they can't do amazing work in KC.

In Chicago and New York I see the same thing. People doing amazing work and people complaining about how x, y and z are holding them back.

If you have a great company, you could be in Boondock, Iowa for all I care. Likewise, if you're the type to make excuses, there isn't a city in the world that will make up for that.

It doesn't matter where you are, it's what you're doing that counts.

One of the classic moments in the history of common law was the emergence of Equity. It arose because the strict, predictable rules of Common Law as it then existed were leading to what were clearly unjust outcomes.

Sometimes no specific rule can capture the correct action. You need room for judgement. It bugs the everliving daylights out of me that so much of law is undecidable and informal, but it is so out of historical demonstrations that a balance between robustness and strictness is required.
Even if they are expensive, everyone will want these. I know I will be first in line. If these are reliable, and their drift friendly modulation works, we probably won't see spinning disks in 10 years. Thats a great future.

This author seems confused. Sabermetrics refers only to baseball statistics. It's improper to use the term to refer generally to all sports statistics. In addition, generalizing from baseball to other sports and then back to baseball ignores the fact that baseball statistics are much more valuable and telling than those in other sports, for various reasons, the most significant of which is that batting and pitching stats represent a large number of discrete events involving only two players and influenced only to a relatively minor degree by actions of other players. This isn't true for stats in any other sport.
No? Okay, let's just downvote the comment then.

Electively killing an animal is fundamentally incompatible with caring for it as a living thing -- as non-property; something which has the right to live it's life independent of any human's design for it. Without forgoing your intent to eat it, the best welfare you can give an animal is the treatment of property, as a valued investment. Given that you opt for these animals to be killed anyway, your call for their improved treatment is, I expect, designed first to benefit yourself and your own mental and emotional state. It has only the secondary effect of improving the animals' lives.

I actually don't have a problem with social networking. I know where FB and Twitter sit in my world. I use both of them regularly. I don't see how + is significantly different than either of those products. I've already hidden most people I don't need to see on my FB feed and of course Twitter is curated by people I'm interested in. What else am I missing here?

EDIT: Let me follow that up by saying that the majority of my conversations that could be considered 'social', still happen in email. Is that a problem someone could solve? Or is that too far fetched to be solved by a social network?

Maybe the server generates the private key/public key pair, then derives the domain name from the public key (eg, long-random-string-that-comes-from-public-key.dyndns.com)? This derivation process could be the "encryption algorithm" the article refers to?

The client is given the new servername via the P2P network, then derives the public key from the hostname, encrypts using it and communicates with the server which can decode using the private key.

I'm not sure what the max length of a hostname is, which might be a problem.

Another possibility is to put the public key in a TEXT DNS for the server hostname. That could be what they meant maybe?
I think that the complaint is not with regulation in general - it's with poorly executed regulation.

This is a fantastic explanation. I've always had trouble "getting" imaginary numbers.... even though I've had to use the fairly often as an Electrical Engineer. This is the first time they've made intuitive sense to me.
And the people in the 90% that don't want to pay lawyers 500$ an hour? That's what I mean, as far as I can see I don't follow as to why that does not necessarily dwarf the concerns of the remaining 10%, and also it's not even a granted that this would actually happen. The emergence of equity in common law is one thing, but common law is administered by humans, a system written in code to which anyone was free to contribute and which was administered by computers would be far less susceptible by nature to human error.

The only scope for human error in such a system is the process of coding itself, and massively distributing this and opening that process as much as possible makes any bugs in the system shallow by comparison, as well as easily demonstrable by test cases rather than actually requiring some clueless politician, lawyer or judge to make a terrible decision and someone else to suffer the consequences for it.

>>> How many people have committed crimes that could have been prevented with a mental hospital stay? <<<

Isn't this essentially equivalent to pre-emptive punishment? If you abstract it you could say, how many murders will stop if we lock up anyone who has ever been in a violent altercation? It is compelling in some ways, but this list also includes anyone in a very stupid bar fight. The real problem isn't even the haziness of the line, it's where do you draw the line.

Is being gay evil? Not too long ago it was viewed as that, and feminine boys were quite often put through hell. I really don't want to live in a world like that. This led to atrocities like these; http://en.wikipedia.org/wiki/Aversion_therapy#In_homosexuali...

The problem with a lot of psychiatry is the game of vested interests. For example, people making the DSM have a vested interest to categorise deviations from the social norm into disorders which require their own unique brand of "therapy". If you add in the fact that most of psychology research lacks proper scientific methodology, and its often used as a platform to prove a point, which somehow always agrees with the researchers prejudices, you get people juggling grenades on a glass slop, while balancing on a wet soap bar.

In my opinion, a very poorly written article, but here are some of the main points:

1. estimated 4.5 million infected machines

2. it infects the Master Boot Record

3. it uses the Kad Network (http://en.wikipedia.org/wiki/Kad_network) to issue commands to the clients (No idea how, the article did not explain this)

4. it disables competing malicious software

5. it acts as a malicious software manager; they install software for their "customers" to temporarily use

Instances are already IO bound/capped.

For example, if you start up a micro instance, you'll only be able to download at like 200kbps or something.

So I'd assume the connection speed is linked to the size of the instance, and the bandwidth cost is integrated into that cost somewhat.
This might be very related, actually - Dropbox just sent out an email announcing downtime for a move to a different data center.

That's a valid question. Maybe you're right. Let me explain it to you this way if I may. I may not be sure if I have problem, until it's explained to me that I'm missing something and thus a problem appears (isn't all marketing just that?). For example, my Dad runs a small biz and every week collects his employees time information by hand and calls Paychex to input the payroll. He doesn't really have a problem doing this, although it takes up nearly one hour if not more a week for him (or every other week). When I showed him tools that automated this for him and saved him time, he was quite thankful. He didn't realize he had a problem spending one hour every week (or every other week) doing this work, until I showed him a solution that made his current system seem problematic.

At the moment I feel like there is more to social than just FB, TW and email. However, I can't quite pin point it myself - and I've tried. I was hoping someone quite smarter than me would do it, but they missed, and a by a lot in my opinion.
My problem with IE9+ not supporting XP is that XP users (still a fairly large % of visitors) will still be on IE8. Some of them can manually upgrade to a newer OS or a different browser but many will be "stuck" for a few more years. Even if IE10 was released today and (perfectly) supported more web technologies than Firefox and Chrome combined then IE would still be my biggest problem in front-end development.

Microsoft have (likely) spend millions on getting XP users to upgrade to Vista / 7. Releasing IE9 / IE10 for XP seems to be the most feasible way to upgrade these IE8 users. An upgrade to Windows 7 through Windows Update isn't going to happen and I can't imagine MS bundling a 3rd party browser to replace IE8 on XP.

The act of writing programs, and discovering a bottomless well of bugs in those programs, is what has made me respect lawyers all the more.

I do think some tools and practices can be adapted. I think, for example, that expert systems -- whether classical or hybrid a la Watson -- could make a big dent in that $500 figure. That is definitely pursuable.

But humans inject errors, it's what they do best. And outside of a properly formal system (and per Godel, these aren't perfectly usable anyway) the best way to identify errors is ... with another human.

You might say that judges have been performing software inspections for much longer than we have.

Don't get me wrong, law is as slow as frozen honey. But the problem domain is heinously complex and I expect that any software system would reflect that complexity. Given our profession's iffy track record on creating items of massive size and complexity, I lack your transformative enthusiasm.

I am what you might call a cautiously optimistic conservative. Or a pessimistic radical. Not sure. One blogger I host talks about "radical centrism".

I can't down vote this but I really wish I could. As someone else pointed out this comment seems driven by malice more than anything else...

"Let me tell you what a UX developer is. UX developers are people that couldn't find themselves neither as designers or as developers and got stuck in between."

While I find your tone particularly hateful, this is about as close to being the best definition of how I see a UX developer/designer, without the derogatory tone of course. They are people who want to be involved in the earlier stages of a project, and want to know about the technical aspects of the problem and the design or brand constraints, and are suitably equipped to deal with the people whose job it is to solve the intricate details.

If you are a developer who can turn out a decent user interface, (maybe on a web app you were left to do the settings page), or a designer who can prototype in Javascript to show how modals windows work - congratulations, that is UX - converging the different disciplines to create a whole. Someone who works more in doing that and deals less with the nitty gritty of one or the other is just doing it more, (and probably better for the time and experience they have). Thats not to say because they don't do the nitty gritty that they can't, (although I'll admit my design skills trail off before my technical skills do), its just they are more interested in leaving it to others.

[Aside: I am a technical guy who has moved much more towards doing prototyping and UX work. I find alot of the comments in this thread pretty insulting since they all are assuming I am either a shite designer or shite developer.]

Also, it is far from a given that a mentally ill person is especially inclined towards crime. My mother worked as a psychiatric social worker for an extended period and her opinion was that schizophrenics were less dangerous than just average people.

Certainly, many mentally ill people could use some help and will engage in behaviors "disturbing to the public" (talking loudly to themselves etc). But it seems to me that serious criminality requires a certain confidence and competence maybe not a lot but more than, say

Discussion: Aren't loops the only interesting code?
Sure, but to take an extreme example, suppose you have a division operator that fails to check for division-by-zero. Then your operator works in 100 * (1 - 2^63)% of all cases. That gives you 18 nines and sounds pretty convincing but it's hardly the point.

In the same way I'm wondering how meaningful it is to say that an algorithm works for 99.49% of all doubles, sampled uniformly. In other words, how could I use that benchmark to make a judgement about using grisu3?
