This post seems to completely miss the point of selectors and how you can match classnames and use pseudo selectors. This isn't a bug in jQuery at all, but just the way css selectors work.

Especially telling is this phrase:

Here are some examples of invalid selectors in jQuery because they contain invalid characters:
$( "#person.name" ).addClass( "highlight" ); // FAIL

This is of course a perfectly valid selector, selecting a node that has both the id person and the class name. Saying that the selector is invalid is simply wrong.

"The Final Frontier of Reverse Engineering" talk by GeoHot
I sometimes see C++ code where all the member variables start with "m_". I'd much rather have it enforced by the language than in a coding convention. (I personally find Ruby's explicit "@" prefix for member variables prettier than Python's explicit "self.", but that's minor.)
Also, it's the simplest thing that can possibly work! (And for very small values of x is also the best possible implementation.)

This is what gets me - the time. In things like Payroll, or Merchant Accounts, where I have a ton of options, I could spend all week on hour long con calls, just to get pricing ball parks from all of the viable vendors. I don’t even need hard prices on a website - but I could really use 1) people that are willing to talk to me for 5 minutes, not an hour. 2) some reason on the web site to choose your company to devote my time to.

Interestingly what this lack of info usually leads to is us going with services our friends and acquaintances suggests - we just don’t have the time to listen to all the salesmen.

Just one anecdote on that point. I'm pre-med and I recently shadowed the director of cardiac research (a cardiac surgeon) at the big hospital/medical school in this area. He was asked point-blank by a patient, "I've been reading that with diet and exercise I might be able to reverse my heart disease. What do you think?"

The doctor's answer was, "Absolutely not."

This is one data point, so it's hardly conclusive, but coming from a doctor who (a) teaches doctors and therefore plants seeds for the next generation and (b) should be an expert on new medical treatments with his position as the director of research, it's troubling.

Meanwhile, there is a growing minority of doctors who take patients through an eating "bootcamp" where they help them take out processed foods/white-flour/high-fructose corn syrup from their diet, teach them how to shop and cook plant-based foods, etc. I saw a documentary on it, "Forks Over Knives" I believe. Fascinating stuff.

In the documentary, they take a man with advanced heart disease, cut out all meat/dairy/processed foods from his diet, and take before-and-after blood readings (cholesterol, blood pressure, etc.). It was surprising how quickly the intervention reversed his numbers.

There are other pioneers working in this area. There's Dr. Terry Wahls, an MD who reversed her multiple sclerosis by eating what some would call a "paleo" diet (only vegetables, fruits, nuts, meat). Here's her TED talk if you're interested: http://www.youtube.com/watch?v=KLjgBLwH3Wc She's currently working on human clinical trials to test this diet-intervention in other patients.

To your point, "all doctors say eat better, etc." I have two thoughts.

1. I'm glad you have doctors who have mentioned that but I've never had that experience.

2. A doctor who says, "You really need to eat better," is not quite what we need. For reversible conditions like heart disease, diabetes, (MS?) etc we need doctors who say, "Your next appointment will be with a food specialist/nutritionist. He will help you completely change your eating habits, go shopping with you to get new staple-foods, and you will stick to this new lifestyle for x months. Here's a list of foods you must not eat and here are x great-tasting recipes that are easy to make. Come back in 6 weeks and we'll do another round of blood-tests to see how it's working. If you're not willing to do this I can give you [statins, etc. fill-in-the-drug] but they won't actually treat the disease and may not make you feel better. They will keep you alive though. It's totally up to you and I'll support you in either decision."

Just my 2 cents. I think medicine will eventually look more and more like this, but it will take time to change the culture and the traditions of western medicine.
Awesome. I wish all conferences had live streams. Will be tuning in throughout the day.

Search engine for people by property of the person
Judging by many of the posts of /. and reddit, the level of distaste with the 'Battle.net 2.0' scheme for Diablo III is much higher than what it was for Starcraft 2, probably owing to SC2's inherently multiplayer nature and the huge deviation in gameplay from Diablo II to Diablo III.

I has been common knowledge for a while that Diablo III will likely see a console port. Looking back, it's hard to imagine that that didn't severely impact the design of the game.
Besides being Ruby, that's not a closure, just an anonymous block/function. A closure closes over some non-local variables, while that block doesn't.
The way of life effect
Mike McCandless, a search expert who does a lot of work with Lucene wrote about what he found in this mit paper about extracting side effect info from online health forums:

Here is the less lengthy, less academic blog post from him, he may be talking about the same thing that nature is talking about, or at least it's something very similar:

Yeah, location arbitrage. There is no way to trade equities faster and on better information than if you're faster than everyone else. Having this 30ms advantage will give whomever has it a huge advantage.
It (lawsuits against municipalities) has yet to reform how law enforcement works in the U.S. I doubt it will work to reform the patent system. That being said, maybe there is a "tipping point" where tax payers & pols alike say "enough!"

"The government can't just take property from someone, and if they do, they have to pay for it," said Dowell. "Just because an entity is funded with taxpayer dollars doesn't give them the right to steal property. My client now owns 34 patents that are being infringed, and what else is he to do?"

You cannot support patents and at the same time tell us, with a straight face, that somehow it is still for the common good.

Pirates are accused of stealing for the way they handle IP--what mental gymnastics are folks willing to go through to condemn this while condoning that?
I disagree, the value we get betweeen free and what we really need is not equal to $120 per year per employee.

I think you have a bit of a bias because you're coming from the side that dropbox is on, where you have a service you sell.

I sit and use the service daily, along with my colleagues and to get the few extra gigs per needed does not == $100+ per month.

I think there is another offering option which would meet more needs, maybe the one I proposed is wrong, as was pointed out - but the need is not wrong.

I think I have seen you say "charge more" a lot on HN - while this sounds like "no nonsense" business confidence -- it alienates users who don't find you service to be worth what you think its worth.

If, to you, that means "fuck those users - who wants em" then that's ok - but don't blame users who hold your services at different values than you do.
Wouldn't it be easier to generate electricity from extreme heat, rather than from cold water?
Innovator’s dilemma in programming languages
If it's like SC2 then they also think they control rights to the content created by the game. For example, they believe they are entitled to royalties if you run a tournament.
Yes. One of the problem with that is unfortunately quite silly. We don't know the exact position of submarines, since the water interferes with the GPS-like systems and makes them unreliable, while neutrino beams need to be highly collimated to create a big enough flux.
Thats exactly what I am asking. I am paying for 50GB, I have shared out folders from my source to free users. If I put 2GB in those folders, all the free users stop syncing.

I think this is wrong.

Not sure what you are accusing Apple of ... This developer does have a choice you know. He could have made a trial available on his own site. Apple does not disallow that.
That's interesting that you consider your online persona distinct from yourself. I find addressing you as raganwald here on HN as awkward, so I have instead called you by your first name. Do you have a preference? Is that preference related to the distinction you wish to maintain?
This by itself is a great selling point of d3, in my opinion. You can inspect everything about your visualization using the browser debugger, and it's easy to figure out how the objects in the DOM correspond to your code, which is a blessing. The first thing anyone should do when checking out d3 is go through a simple example and then open up the debugger and see how transparent the connection is.

Also, I think a non-programming designer could understand and tweak the CSS without much guidance from a developer, using only an understanding of SVG.
When are we EVER covered in the media, other than to talk about how much money is flowing through our companies? This is amazing.
SC2 players hate Battle.net 2.0. I don't think Blizzard cares too much, since they are focusing on the larger casual market. They originally stated that there would be no chat channels ("why would you even what them?"). That makes sense for a casual player who is already on Facebook and uses that to communicate with their friends.

This captures something I've been thinking about for a while, it seems like there's about 1 or 2 life-changing apps/services a year.

Dropbox fundamentally changes how I collaborate with non-coders, makes it somewhat more like version control.

Instapaper changes how I browse and work...much less tabs these days and less "interruptions" from new content.

Spotify means I never have to micromanage my music collection again, or even worry about all these cloud music hosting services.

It's not for every startup, but the potential to change ways of life is definitely a good litmus test for an ambitious startup.
Very tempted, but I resisted!
What actually matters is the temperature difference between two points.

But to answer your question, sure, probably - assuming your materials can withstand the extreme heat, and assuming you can get at it, which as sp332 pointed out here (http://news.ycombinator.com/item?id=3708465), we can't.
I second the idea of building your own deb.

But if you're going to learn a DSL for building debs, why not just learn how to build debs? Your distro already provides the necessary build formula, along with well-integrated startup scripts, etc.

To start out, just build as given:

apt-get build-dep nginx
apt-get source nginx
cd nginx-$VERSION
dpkg-buildpackage

Then to customize, go into the source tree and update whatever you want to update, and rebuild. You'll see there's already a debian/patches directory where you can drop patches to apply automatically.

I tend to just keep the "debian" directory in source control, so I can take a fresh upstream tarball, check out my debian rules into it, and kick off the build.

There's also remembering your strategy index tables. True, that's not a lot of numbers - some might use as few as 18 indices - but still: You're keeping in mind at the same time (a) the count, (b) a set of basic strategy rules appropriate for your specific game (c) a table of strategy variance index numbers appropriate for your specific game, (d) a deck depth estimate. And probably a few other relevant numbers.

(here's an example of the "Illustrious 18" set of strategy index numbers for one counting system:

Hey Reg, I'm curious to what extent you believe that private citizens have a right not to be reported on. If Annie Lowrey had decided to interview Reg Braithwaite and couldn't get a hold of you, if she'd pursued a similar course of action, would it have been intrusive?

I get that having made something public once does not necessarily mean that one opens their life up to scrutiny forever and ever, but to what extent does closing down one's works and leaving the public eye entitle one to a lack of scrutiny/inquiry?

(As an entirely meta aside, I'd be curious to what extent the cultural divide over privacy ethos between Canadians and Americans is at play here. My impression, at least with my wife's Canadian family, and our collective friends, have different expectations from the Americans i grew up with.)

Heart disease can be plaque, which, theoretically, might be removable with some diet change. It can also, however, be hardening of the arteries, which is a loss of elasticity of the artery walls. We don't know how to reverse tissue loss of elasticity do we? So when he said it could not be reversed with diet, that seems to be correct to me.

Awesome discounts at Codersky
I've been noticing the same thing about so many sites in the UK lately. And it's the IT related industries that seem to be the very worst it. I was gathering some competitor intelligence for most of this week and noticed that there were very very few sites that were transparent with their pricing. Its wrong on a few levels, but when everyone else around you is doing the same thing sometimes its not so obvious how bad for business it really is.

we're setting all our sites up with transparent pricing now.

Or maybe not. It could be an HD release of the original two games via steam which has long been rumored.

Unfortunately that would be just as bad for my productivity as the release of a new game in the series.

This would make sense if it were just a question of getting all the feature boxes checked off and implemented. The fact is though, in language design each feature tends to complicate everything else. For example, I suspect good error messages, debuggability, and IDE support are all set back by this.
Show HN: Piglet, the fluent parser
But... Uhhhh... that was Ruby you just showed there. And Python's anonymous functions are deliberately crippled because the Grand BDFL dislikes functional programming (often tried to be sneaked around by those dastardly Schemers, curse them!).
I think the core idea is that Battle.net 2.0 represents a step back from SC:BW Battle.net in most regards, and the only steps forward don't make Battle.net 2.0 nearly as functional as WC3 Battle.net.

Only time will tell if their IP has the traction to overcome the limitations of their system, and how that impacts future iterations of their games.
We don't need Python in the Browser.

We need a VM SPEC for the browser, so we can have whatever language we damned well please in the browser.

Why Google decided to go with Dart rather than publish a VM spec is beyond me.

We're set up across multiple AZs in the affected region, and all we had was a few minutes of failed requests to one AZ until our systems automatically shifted all the traffic to another.

Even the major day-long outage last year because we had (at the time) not really spread ALL our core systems across multiple AZs. We just re-launched those systems on another AZ and everything was up and running again.

Which outages have affected multiple AZs?

Something to bear in mind regarding non-standard string libraries: syscalls (like open[1] on POSIX or CreateFile[2] on Windows) use null-terminated strings, which means that you have to be careful about embedded nulls, no matter what library you use, when a string gets passed to a syscall somewhere in the chain.

This may not be helpful, but does an issue arise when a large number of defectors believe they're cooperators?

And actually, as katovatzschyn kind of points out, this setup (citizens / military-industrial complex / terrorists) may not actually map very well at all to the cooperator / defector / joker model.
I've tried a number of email clients on the iPhone. In the end, i nearly always end up reverting back to the default app. There's something about the simplicity of it that always brings me back. That said, the other apps were always slower fetching mail from gmail which never helps. The only app that i have found to be very good is the gmail for iPhone app, but i only use it occasionally when the default app cant find an email address from my gmail address book. I should really use the gmail app more. Its mostly good enough.

Either way, whichever app i settle with in the end, its going to be the one that is the quickest in operation.
Yes, I think you're right. It's better not to support it and it will be good for our productivity, too.
Read my post in the same reply level. The creator of the language believes macros will actually make the language simpler. This is made possible by the fact that other language can be re-described and re-implemented in terms of macros, possibly even turning some language features into libraries. In his interview with InfoQ recently, we learn that his long-term goal is to decrease the size of the language in the future if possible. Directly from http://www.infoq.com/articles/odersky-scala-interview:

InfoQ: There has been some debate in the Scala community about the need to add features versus keeping it lean. Can you give us a sense of where Scala is headed? Does Scala need to become a bloated multiparadigm and multipurpose language to be considered mainstream?

Martin: I think the consensus is very much that we keep it lean. Scala is a compact language despite its enormous spread of use cases because it has always tried hard to unify things. The same concepts describe objects and functions and components. Instead of adding features, Scala has very powerful abstraction capabilities that let users define similar features themselves in libraries. In the future my ambition is to make Scala an smaller language, not a larger one. I know it is hard, but we will try.
Just re-read your post.
