That applies to ARM. I'm not sure of the equivalent workaround for x86_64 outside of installing a 32-bit Java 7 and setting that up as the source of the Java plugin.

> North Korea is a liability that they may well decide that they cannot afford.

Hard to tell. On the other hand, their influence over North Korea is an asset they can use in negotiations with other superpowers. Plus, they start to look good in comparison.
I guess you're trolling, but anyway.
All politics aside, the people in NK are hungry. Hungry as in "I don't have anything to eat". There's no doubt about the fact that the Western World managed to get this right.

A friend of mine bought the developer-prerelease version a year ago(it has extra 2 electrodes), it is very hard to train, he got some success, but basically it is a novelty, can't really use it as a practical device.

Also there was a rather restrictive licence on the out-of-the-box software, which is not very productive for a hardware company.
Ask HN: Would a mockup presentation tool like this be useful to you?
This is probably more relevant to designers and people who frequently present design mockups to other people like clients and colleagues.

I'm a designer and part of my job is to present design mockups (web usually) to clients and colleagues and to make sure the mockups look accurate (like they were in the browser) I would put them in HTML pages so the images and background and margins etc are nicely done. I then upload the assets to a subdomain of my blog or S3. I would then explain my design in an email. It's a major hassle and not the best way to communicate design choices.

I created a tool called "Mocku.ps" that simplifies this process into a few clicks, with annotations like the what you get with Bounceapp.com. And then you just share that nice shortened URL.

You can use it at http://mocku.ps/.

Do you have the same problems as me? Is this something you would use often? Is the interaction simple enough? Would be great if you can try it out and give me some critique.
Until recently I dismissed JRuby, but then I needed to run some stress testing code against an Oracle DB. With MRI Ruby and the OCI8 library, the Ruby overhead stopped me being able to push the database hard enough. I switched to JRuby and JDBC and the results were amazing, so I am converted. The only niggle I have is the startup overhead, which I know is a JVM thing. Not a problem for my benchmarking, but a little bit of an annoyance for a command line ruby tool I use.

As an aside, I did run across a bug, not performance related, but a case around popen where JRuby doesn't behave the same as MRI - I raised a ticket (JRUBY-6225) but it doesn't seem to be getting any traction. I understand there are probably plenty of tickets to be prioritized, but this one is a bit of a show stopper for me. If anyone from the JRuby team is see this and has time to have a look at it I would be grateful.

Honestly, I think I just don't understand it. When I call the method doThis() on some object implementing the interface Thingamabob, I am assured that it will do whatever Thingamabob::doThis() is obliged to do. Of course Thingamabob is short for a fully qualified name, there is no ambiguity here. And of course I am relying on whoever wrote the doThis() implementation obeying the contract of Thingamabob::doThis().

With duck-typing, how do I know that doThis() is actually an implementation of a (non-declared) interface? The chance for accidental clashes seems exceedingly high, the space of method names is not all that large. And what does it actually buy you?

A silly question: Can I call jruby or jirb with something like classpath?

I don't want to lose my java applet for firefox,(ubuntu 11.04 64 bits,four-cores).

I would also like to see some comparison, for example like in the computer benchmark game between jruby and other ruby implementations.

What about clojure and scala? will they get a speed up with the new java 7 update? , Will it be three-fold like jruby (in certain cases?). Thanks for the great work on jruby.

That guy strikes me as "Bridge on the River Kwai" - happens to be rarely well educated in a crippling environment and knows the "leader" is not a good person but to hell with that he is going to do his job as good as possible even if it means his own destruction and furtherment of the enemy standing right in front of him.

Evil dictators are evil - so are all the people that do their little part to help him because they cannot find anything wrong with doing their little job as best they can.

But so is a mindless military in ANY country who sign on to take directions to kill other people at the behest of a single leader that they aren't supposed to question.

> I don't understand why all this urge in the "west" to
> change the north korea

Going in and 'freeing' a country is never as simply as it seems. That said, North Korea is not in a very good situation currently. There is a very real temptation to 'swoop in' and 'save' them. The idea being that rather than waiting for (possibly) decades for change to happen (and all of the suffering along the way), we could instantly change things for the better. The problem is that this drastic change is tantamount to revolution, and revolutions are never easy or clean.

Assume for a second that the US was perfect, and we could somehow attempt to impart this to the North Koreans. The population of North Korea has under gone over a decade of anti-US/anti-West propaganda. A not-inconsequential number of these people are going to violently resist US/Western involvement in North Korea. Even if we were able to produce irrefutable proof that all of the propaganda was a lie, there would be enough people that would violently refuse to believe even the truth that was right in front of them to produce significant turmoil.

Of course, we can always use help too :)

You can certainly just call JRuby directly with the 'java' command, or just set your environment to point at the Java 7 install only when you need it, rather than forcing your whole environment to use Java 7 by default.

I imagine the computer benchmarks game will update when we have a release of JRuby 1.7 out, sometime early 2012. If someone else wants to do some benchmark runs, I have no objection.

As for Clojure and Scala...they may see modest improvements from Java 7, but neither of them use invokedynamic at all. The biggest boost for JRuby comes from invokedynamic.
I've not gotten the impression that North Korea really likes China, just that they tolerate them (because they are the only ones willing to deal with them). Maybe things will change a bit now, but I was always under the impression that N.K. could have easily lobbed a nuke at China 'just because.' That kind of uncertainty is a liability.
Why it is necessary to hire professional web designing Company?
I've just read the girl's story on her blog, and I know I may sound as a rapist-apologist or something, but frankly I don't care: she was just plain stupid by getting drunk in front of all those guys, performing dances wearing a short skirt and "sitting on laps". I didn't say "she asked for it", I'm just saying "she was stupid". Of course that Twitter guy is in all honesty a jerk (as was Bill Clinton or Dominique Strauss-Kahn and lots of other very bright men, intellectually speaking), but if this girl cares about her "safety" and all that she shouldn't play the role of Little Red Riding Hood in the land of horny, drunk and sexual deprived techies.
Interesting that (from the MITx FAQ) they will provide the classes free of charge but will charge for certification. Has a thread of similarity to an open-source business model. :)
I have a similar problem but it doesn't stop me from being a good programmer. What it means for me is that when I sit down to work on a large project, it can take me a while to get up to speed with it as I reload/reaquire the knowledge. And I think that's totally normal.

In your case it might mean that your memory isn't "flaky," but rather that the way you perceive the content of a program is high-bandwidth, which would imply deeper understanding of the content even though such perception has the side effect of making your memory seem worse.

Still, you should check with a doctor on whether you might have some weird anemia or something.

Handling 404 Errors with PHP, by Chris Shiflett
My wife worked in the city for one of the big banks. A chap who worked there was in a similar situation. He missed the train that had the bombers on board, but he decided to grab a bus to work instead. This also had one of the bombers upstairs which moments later detonated killing most of the people on the bus.
What made it even worse is that everyone who died that day was taken to a makeshift morgue on Moorgate which is overlooked by the people who worked in his team. A really shocking day.

I probably have a parsing problem here. Can you help me solve it?

Knowing not a lot about Go I followed the links and saw that interfaces are 'implemented' implicitly, the quacks like a duck way. If I fulfill the contract of an interface I can be used as something of that interface. Cool.

But - what is Rob's comment now?

"It's always bothered me in OO languages that we can make Circle, Square, etc. subclasses of Shape (say), but that's the one design decision we get to make. What if we want to align those things along other axes (so to speak), like topological genus or plant genus, if you're a landscaper? You might lose your way or dig yourself into a hole with multiple inheritance." (goes on, imo down the same route)

From what I can tell there's no issue here. Except for the requirement to be explicit (implements Foo, Baz, Baz) instead of implicit (just add those interfaces' methods on your type) the very same thing can archived in the biggest (market share?) OO languages. Java? Check. C#? Check.

What exactly is leading to this final quote:

"Go's interfaces aren't a variant on Java or C# interfaces, they're much more. They are a key to large-scale programming and adaptable, evolutionary design."

I'm honest here. I don't get it. Duck typing? Yeah, fine. I think I'd like that. But what am I missing? It seems in Go you get two things: No need to explicitly annotate the types with the classes it implements (good or bad, probably depends on taste and general complexity of the code) and, perhaps bigger?, you can probably extract interfaces later which are now magically implemented. But both features seem to be ~refactoring/design~ details. Nifty maybe, if they fit your style. But not a leap in any way?
I think saying that they need communism--or even that they would be worse off without it--is a little much. While the state provides everything, that's just a relative measure: in an absolute sense, it does not provide very much at all. I think that they would be better off without communism even in view of the inevitable difficulties transitioning.

The overworked american
Juliet B. Schor (b. 1955) is a professor at Harvard University, where she is both Senior Lecturer on Economics and also Director of Women's Studies. In her book The Overworked American: The Unexpected Decline of Leisure (1991), she analyzes some surprising trends-historic, economic, and cultural-in the world of work, with a particular emphasis on the American worker. In the following excerpt from The Overworked American, Schor examines the shifting balance between work and leisure time, a phenomenon of late twentieth-century life that has produced increasing stress on the individual, the family, and society as a whole. Citing the constant increase in productivity since midcentury, she asks, "Why has leisure been such a conspicuous casualty of prosperity?" To answer the question she probes the values of our culture, examines consumer habits in our four-decade-long national spending spree, and critiques the economic ideals of American capitalism.

Startup Secret No. 11: Rescue your darlings

Ask HN: A credit to site/app's UI designer?
While it is easy to spot who designed the cover of a CD, a book or a poster, when it comes to websites/apps UI, there is no convenient way for that.

The current state is totally depends on the site's owners whether or not to give a credit line, in fact, unless it is a free theme integrated into a blog, in most cases one cannot tell from the site/app itself who is the creative soul and mind behind that specific amazing piece of art one is currently observing.

I am in a point of searching for a site designer, and was thinking, instead of telling one, do me something nice an elegant, minimal and clear such as A or B or C, I should simply hire the one who designed A or B or C directly.

But I cannot found them.

I was thinking what if someone will come with a single form to provide site's design credit(s) that will be easy to adopt and integrate, either via headers, or pre-defined URI or alike.

Wouldn't that will be a nice thing?

IMHO, this will make the world a better place, no matter how small this might look.

Think about a freelance [wo]man out there who will get leads and new business opportunities.

Tell HN: If I ran Twitter, this would be my business model.
I may be crazy for doing this post and may be missing something very obvious, but I can't help feeling Twitter itself doesn't realize how big a part it can play in social discovery.

These days, most of the information you come across is through your social network and this will only increase. The articles you read through HN or Reddit or those new FB Open Graph Media Apps.

But Twitter has always been the best at spreading news fast. It literally feels like wildfire. And yet, they have made no effort to monetize this aspect. I see Twitter as this micro publishing tool for anyone with an account. People with a lot of followers, especially celebrities get paid huge amounts for certain tweets promoting products. But why does it matter how many followers you have? If i was Twitter I'd be applying the Google Adwords mixed with an Affiliate program model.

People could pick and choose ads they wanna feature within their tweets or for those who don't websites could link your twitter account to every time you tweet one of their articles, and just like a Google Adwords ad, you would get paid for any one who clicked your tweet and linked back to the website. This is what Dropbox does in a Referral program way where you have your unique link and every time someone signs up you get additional free space.

This is true Klout, because that is the most important information to a brand. Today, anyone can become a referrer of information, you don't even need a website anymore, and Twitter should really look at linking the referrers to media websites or big brands or SME's that work with Google. They should treat each individual account as Google treats a publisher with a website. Instead of brands doing Google Ads, i think they would much rather compensate real people doing it in real time within their sphere of influence. Today, if Paul Graham tweets something with a link, lots of people will click it, so why shouldn't he be compensated for that?

But What do I know?
