Theres some truth to it. Despite how revolutionary quantum computing could be, there still aren't a lot of quantum algorithms that are asymptotically faster than their classical counterparts. The two important ones are Shor's factorization, which can factor an integer in O((log n)^3) time, and Grover's Search, which can search an unsorted collection in O(sqrt(n)) time.

Grover's search is pretty amazing though - a lot of problems can be reduced to some form of search in the solution space, and sqrt(n) search will let us say "fuck it, lets just brute-force it" to much bigger search spaces. I could see that being applied to the example you mentioned - searching through a list of possibilities very quickly.
"and it is not up to you to decide whether or not he has the right to feel offended or not."

That is probably the heart of the matter in all these situations.

The story itself though seems, err, one sided. But it has a great Panda picture at the end.
I did 2nd on AngelHack Paris on last december, really great and inspirational event! The best hackathon for sure.
In the application code, you can use either annotations or XML, or both, it's up to the developer.

And regarding editing XML in some other required places - you can use Gradle instead of Maven or Ant (thus no XML files). But that's not the point, to get rid of all XML on your server. The point is that in the application code you are not obliged to use XML.
I think I should add that it's not just about the language, it's also about the architecture. You need to know what's going on and where, and why.

>> I think a lot of it is Silicone Valley's attitude to being different to the rest of the world, the majority of sites are built in PHP? Sweet, let's go with something funky and different!

I don't think that's it. Personally, I switched from PHP to Ruby because 1) Ruby seemed like a great language and 2) I saw a lot of excitement about Rails and 3) it seemed like a marketable skill.

But a few people had to decide #1 for #2 and #3 to happen. I think any new technology gets its initial hype because of some merits it has, even if the hype later gets out of hand.
You know, I was going to say that my advance for my last book was pretty decent and I'd be surprised that it would be much worse than a midlist SF novel.

As Tom Leek points out, it's not safe, it's about reacting to tampering.

Nothing is inherently safe, so the key is to have the money inside rendered useless.

Be it broken-glass, seals, radio/gps, there are probably many other ways of detecting non-normal use (given ATMs is usually bolted). Add that to the fact that it's incredibly risky and difficult to physically remove.

What you would end up with would be useless or marked money.

So, it's not 100% secure, but it is a futile target.

Off topic: You can compare this to cryptography. Given an attacker has (physical) access and knows your system, it should still be impossible to crack.

More or less what happens is

There's a pool of generators that put energy onto the grid. Each one has a price per MW generated (or MW/$)

Generation is metered and consumption is metered.

So the consumer will say "bill me for the cheapest one" or "bill me for renewal one" (or better, contract a certain amount of power from 'FlowerPower Gen'), and the producer will have "I'll have to produce X MW to provide for contracted demand"

But in the grid it's mixed, of course.
Death Threat?!? Doesn't "you are a doormat" just mean "you are letting yourself get trampled upon"?

Calling that a "death threat" looks an over-reaction on a par with Ms Richards' original one to me.

In the example image you provided even, there's a few areas that could do with colors.

In all you should be able to use the three semi-transparent blocks (25%, 50%, 75%) in combination the 16 foreground and 16 background colors. There's a lot more shades than you'd think — http://i.imgur.com/OCrg5FZ.png

I never got around to dithering or mapping half blocks when I attempted something similar a few month back, but with enough colors in the cable things started to look (almost) smooth — http://i.imgur.com/18T6QoY.png
Wow. Just wow. So telling a racist (was it really racist? i think it was just stupid, people make fun of things they don't understand all the time, if this joke offends you, grow the F up! Would you really "cry" if someone who doesn't understand your language said it sounds like random noises?) joke is totally unacceptable, but calling people idiots, cows, goats, assholes, autistic and aspergers is okay? And this guy knows Calvo has asperger because he doesn't have empathy, but he's completely okay with causing them such an embarrassment and making them cry and remarking it in cold words?

Someone complaining about racism can't be spouting sexist comments on a blog.
Exactly.

Only, it's changing the age-old term strawmen to "strawpeople" that is the language policing here.

Dude, Play 2.x is perfectly fine for Java and will always support both languages.

> You're mixing up what I said: a sociologist describing a social phenomenon is analogous to a physicist describing a physical phenomenon.

Sorry, no. All academic disciplines are not analogous and equivalent. The sociological re-casting of "racism" that we are referring to here is an opinion, and not even a majority one at that (among sociologists).
The sad thing about this if it's true is that people will most likely claim Apple are some revolutionary company that invented flat design when Microsoft brought it to the commercial mainstream first before anyone else did. Flat design is in my opinion, Swedish design. The swedes have been designing with a flat perspective long before Microsoft or anyone else made it a trend.

This. Ruby may be slow compared to compiled languages, but after working on Rails apps where it takes 30 seconds to run the tests, I was delighted to develop a gem using TDD. My gem has 100+ tests, and the suite starts and finishes in less than a second.

Our apps' tests suites are slow mainly because of database access, secondarily because of Rails, with Ruby itself being the smallest factor.

I agree. I got to the first "stupid cow" and stopped reading. The writer lost any empathy I had for them at that point. The response to any form of discrimination or harassment is not name-calling.
Why is the Bitcoin Ecosystem so Insecure?
Not sure how that's been passed up in favour of talk about the UDID change. That's quite a big move from Apple really.
I respectfully disagree, but that's because I'm in a couple of communities that are very, very cleverly moderated and have very rigid curation guidelines that the mods are careful about.

You still get people trying to shout at each other, but they usually do so from a distance, and not within the community. I'm perfectly happy with that.

HN has moderation (flags/upvotes etc.) but a much less rigid set of curation guidelines (see "Six Degrees of Hacker News"). This results in a much wider set of "well I think HN should be X", and therefore more meta-arguments about the different Xs rather than staying on topic, whatever "topic" means to each individual.
> You see, at this point, I am already convinced that Calvo has Asperger's Syndrome. He is unable to see things from another person's perspective, he has no empathy so he cannot see why or how I would be offended by his racist joke.

#1

> His Asperger's Syndrome had made him unable to read the signs to see that I didn't like him - he had somehow convinced himself that I actually was his friend and that I liked him. Good grief.

#2

> I don't buy that Asperger's Syndrome thing.

Well, either he is convinced, or he doesn't buy it.

> I think Calvo is just an asshole. So much for modern psychology and medical science, someone's an asshole - you give it a fancy medical condition and suddenly they have a disease, a psychological condition.

#3

Just be thankful that "people with Asperger's Syndrome" are possibly less prone to kick up a shitstorm on the 'net, because after the second "good grief" you were well on the way to deserve a good one.
This is how we should read hexadecimal
I haven't used Apple's system, so I can't comment on it. However, Google's system has a few gaping holes that make it far from effective from a usability standpoint.

First: A large number of Google's web applications still rely on application specific passwords. This was understandable a year or so ago, but still? It's getting very tiring generating an application specific password for some Google applications.

This brings me to my next point: the use of application specific passwords has been made complicated than what's required. When confronted with a page that asks me for an application specific password, it takes too long to navigate to the correct page so that I can generate an application specific password.

Thirdly, I can't change the name that I give to an application specific password. Discovered that you have a new installation of Chrome on a VM and want to create a password for that? Too bad: you can't rename the existing password so that you can distinguish the two easily.

Lastly: Have you checked out the mess that's the management page for it? It's extremely confronting. It takes a bit of getting used to. In-fact, until very recently it was rather buggy. For instance: the page used to have a date which showed when an application specific password was last used. This date always had the year 1970. Who lets these kind of bugs through??

> I realize these two individuals involved are Spanish and German - maybe they think it is okay to act like that in Spain or Germany, but no way, not in the UK.

This is exactly the kind of bullshit, patronising and condescending soft nationalism / xenophobia that is very common here in the UK, us foreigners face here every day and I'd be totally offended by it if I was the type that gets offended easily.
>Really, it's apple, they've peaked already. Show me the new cool thing.

That is just conventional wisdom. Who said they have "peaked already"?

Three objections:

1) People would have said the same thing pre iPhone ("oh, they have peaked with the iPod"), and pre-iPad. And they indeed said it.

2) This iPad thing isn't even 2 years old. Yes, you read that correctly. It was introduced LESS than 2 years ago (actually closing to 2 years any day now, it was on late march 2010). Since then they have also established hi-dpi displays for phones, tablets and laptops, and of course Air-style ultraportables.

3) All the "new cool things" I've seen from third party companies all these years have been ho-hum, me-too stuff (Surface, etc) or vaporware (Google Glasses). It's like, besides Apple, nobody introduces anything that is both successful AND interesting to the mass markets anymore.

Google, for example, had it's moments with Search and Gmail. Since then, what exactly have they put out that's interesting AND has caught on with people? Android: successful but not interesting. Glasses: interesting but not successful (or even "a product"). Etc.

I ended up with a mix when I wanted to run my app on top of a Jetty server. There are projects like jetty-rackup, but when you're on top of the JVM sometimes you feel the need to throw a servlet for a problematic endpoint in there, or some middleware like a filter that you could use for websockets or some library that doesn't already have wrappers packed up as a gem and so on.

JRuby is great, all I'm saying is that when you feel the taste of a competent virtual machine there's no going back :-)

That's an interesting point. Such a law would require reviewing past cases for some 10+ years to clean the system out.
I gather he has written this as a joke but so long, boring and uninteresting that I gave up reading it.

If it is not, then he has got a problem being offended by a joke and at the same time insulting people all around.
Thanks I'll give it a go tomorrow.
There was this time where I was in the mountains, in company of mountain people. These people where quite friendly but one of them kept making jokes about me being from the city, how we couldn't handle alcohol and how lame we where. At the moment I understood that this guy wasn't really mean but that he was clumsy. He didn't know how to approach my differences and did it so aggressively. Just taking the "jokes" well hardheartedly and sending some back showed him that I'm also a human like him.

Just to say. What we need is not more laws but more compassion.
I really just don't even know how to respond to this. I can't wrap my head around how ridiculous it is.

The irony is that if this blogpost was shown to the company in particular, it's quite possible the author would face a disciplinary inquiry.

I think I know where this guy is coming from - these insults he throws are typical of insults in Singapore, and considered uncouth but not sexist or ableist. These concepts don't exist in the same ways in various countries, especially in Asia. All the same, I hope he'll stop his public inveighing against Ziege and Calvo, becaus he comes across as overly harsh and unrelenting.

Ultimately I submitted this blogpost to highlight the action of the company, not the blogger. He did the right thing in telling the people off and raising it to management, but his insults show that he wasn't altogether perfect either. These matters are complex.

syntax is not the only thing behind language design. at all.

the semantics of a language are equally (if not more) important.

you also need to recognise the importance of a good compiler, one which gives good error messages and optimises your code.

> It's almost impossible to take 5 years out of the career game and come back in with the standing you had when you left. While that's not sexist per se, it's incredibly fucking inhumane, and happens to inflict more harm on women.

I couldn't hire someone who had five years without any practice in their trade to most of the positions I hire for.

You seem to be implying that I shouldn't even be considering that in the past 5 years, between two applicants, one has been in the trade, practicing and producing work, and the other hasn't.

That different life choices have different outcomes isn't sexist.

1000 listings, and 50 dollars invested, would mean that even at a 10% conversion rating which I think is safe to say, for a fresh launched website is obscenely high, would mean you were paying 0.5 cents per click. (half a cent).

I don't think your advice is applicable to what the original posters wants.

Without knowing what exactly the OPs business is....

It's a poorly phrased question, 1000 (paying?) users, and retain them for what duration? Are you just wanting 1000 MAU, or just views... With 1000 users, depending on your signup, this could mean a factor of 1:20 of users to views. Both of which could be irrelevant to your actual businesses main metric which is sales?

I view that as a good thing, as cool concepts like Iteratees have been inspired by functional programming and Scala. There aren't many frameworks out there that make it easy to develop traditional websites and web services and do comet/websockets with ease. There aren't many reactive frameworks out there, period.

I also hated Play 1.x because it relied on its own half-baked build system, making it hard to import Maven modules and because the templates were written in Groovy, which for me was a big turn-off, because I like the JVM for its potential for performance and using such a slow dynamic language for its templating was a big no-no (Groovy may have gotten better in the meantime, I don't really know). It also relied on many runtime hacks and bytecode generation, things that have been moved at compile time in Play2 with the help of its SBT integration.

There's many things to like about its preference for the Scala way of doing things. Don't let that stand in the way, as otherwise it's a nice framework.
