> In fact, neuroscientists have recently discovered that the part of our brains we use when making decisions about politics is totally different from the part we use when trying to solve reasoning problems.

It's called caching. Just like it makes no sense for your server to constantly re-generate the same thing over and over again, it makes no sense for your brain to re-evaluate the same thing over and over again. That's what ideology is. The article gets to it, but only at the very end.

No, the biggest problem with democracies tend to be a select number of people who think they know better than the voters and start making decisions for them. That's when democracies turn into bureaucracies.

Bayouborne-

I respectfully disagree. I don't want to beat a dead horse too much since I usually protect my wallet when I hear folks preaching about ethics. (Why is it that ethics discussions usually follow people's economic position?)

That said... I view it as the Golden Rule.

Imagine you're heading to Tulane or Cal Tech or Stanford to recruit. It's taking a day off your schedule, but it's important to bring new folks in to the firm. You screen eighty resumes to interview twelve people, two of which you will bring back to your office for a full day of visits with your team and management. One of the two will get an offer. That's a lot of work. How would you feel if someone was just using this as practice because he would want to work for you later? If you found out, you would blacklist him from your company.

Imagine you are one of the students at Tulane, CalTech or Stanford who doesn't have an offer yet. One lucky guy did. So you are trying hard to get on the interview list at Google, because that would certainly be a great first job out of school. Unfortunately you don't get chosen for the interview. Who does get chosen? Your classmate who already accepted an offer from somewhere else. How would that make you feel? What would you do? Talk to them? Talk to the company?

In the latter case, it's not "Us against evil companies" it is being selfish at the expense of one's peers. In both cases it backfires.

This is about people being professional with one another.

Again - I don't want to rant too much on this, as most folks who lecture on ethics usually have hidden agendas. Thanks for listening. :-)

Do you mean your libraries have classrooms for private tuition? I'm not familiar with this sort of thing. In my country private tuition happens at the tutor or students house.
You mention news and magazine sites, they are very topical and change out almost all of their content on a regular basis.
Your site very definitely doesn't do that and but should.

An easy to find example:

http://www.nydailynews.com/sports/index.html

This is what your home page looks like now, except I'd have more "fresh" content and less duplicate content.

Additionally, under each of the three feature images/stories I'd include the first paragraph from that article under the image with a meaningfully named link to the article.

Try to reduce the duplicate content, for example you have the same article teaser for "2012 Topps Heritage Baseball Cards" image,headline,paragraph on your home page and at least two other pages:

* http://www.cardboardconnection.com/baseball/
* http://www.cardboardconnection.com/sports-cards-sets/

And it;s the only content on those secondary pages. Google will definitely frown on that.

If you have fresh content, you should be using it.

On your second level pages put your most recent article teasers on the page (The teaser is the image/headline/first paragraph combo) like on the third level pages, do your best to bubble the actual content up.
> It makes no sense for your brain to re-evaluate the same thing over and over again

But we don't ever get the result of our query - we never know the true answer to the problems facing society. So I don't think caching is a good metaphor. It's more like we just give up thinking because it's uncomfortable and it's easier to be like everybody else and make up our minds.
So, the electrical engineer in me says that this is because any movement of the magnet would induce an electric potential in the superconductor. But because such a potential would create an effectively infinite amount of current requiring an infinite amount of work, the magnet is unable to move.

Or from a "cause-and-effect" viewpoint, movement of the magnet induces a current loop in the superconductor, the creation of which creates an opposing magnetic force.

Either way I believe this is the same principle behind electric motor braking (e.g. when you short-circuit the inputs of a motor). I believe you would also see a similar effect by dropping a magnet down a tube encircled with many (or perhaps one spiral) loop of wire -- the magnet's descent will be slowed by eddy currents in the loops.

Edit: Aha, this is just half the story. The superconductor is prevented from spinning due to flux pinning: http://en.wikipedia.org/wiki/Flux_pinning (or what the researchers call quantum trapping / quantum locking)

I'm not sure I understand what you're trying to say here.

Why would these nations need "a monolithic MS style set up to keep them afloat"? It seems to me to be the case that a properly tailored GNU/Linux distribution would be a more user-friendly first encounter with a computer than anything from the Windows family (see OLPC, for example), and then there's the whole added benefit of not running a nation on costly, proprietary infrastructure.

Regarding your second point, I get the impression that you're talking with FLOSS advocates. If that's the case, then it's hardly surprising that they are more interested in promoting free software than discussing other social issues.

Thanks. I'm not sure I understand the part about "quantum flux tubes". I take it that they're leaks through flaws in the superconductor (which should exclude the field entirely). Is the superconductor is being gripped or pinned by these lines of force running through it, like a piece of cheese on a toothpick? But that doesn't quite explain how it can move along a field.
The most important UI element in that photo is the little hat in the upper-right corner.
And it's able to move around the ring because from its perspective, the field isn't changing?

betco.in - is mix of three projects:
1) python poker network - open source poker server
2) jpoker - open source jQuery-based poker client
3) the room - front-end for everything of it.

1 & 2 - were existing pieces of software which are actively developed further.

3 - started from scratch.

All of these are open source. Technically anyone can clone github repo and follow instructions to spawn copy of this project.

Project licensed under AGPL which secure all future changes into it will become open sourced as well.
This is the kind of thing that you really need, but that would take way too much time / skills you don't have to do well (or as well as people whose job it is do t his well).

Facebook Is Leading The Direction For Where ‘We’re Going As An Industry’
DJB - I greatly respect what your company is doing, but I think your firm is in the minority. This is why most college placement offices suspend campus recruiting for people who reneg on offers. I cite MIT Sloan only because I found their policy by accident when I couldn't find their undergrad one. This is consistent with what I've seen at many other places. (I have no link to MIT) From http://mitsloan.mit.edu/cdo/policies.php

"We expect that all offers and acceptances be made in good faith. Students are obliged to honor accepted offers. Reneging on an acceptance is a breach of MIT Sloan's Student Recruiting Policies. If a student reneges on an offer, the recruiter should notify Jackie Wilbur at 617-258-6492, as soon as possible. We will review the situation and follow up on your behalf."

It's really quite amazing that I can use 2 factor authentication both my google accounts and facebook. When I see people get "hacked" and lose access to their email and facebook I always advise them to turn it on. Ironically, they decide that its too much work to protect themselves and would rather take the risk. For non-techies I think that mentality is quite common, its quite scary. I wonder if its possible to have an user friendly, secure authentication system.
Exactly.

...I really want to hear from an actual physicist about the "quantum trapping" explanation. I feel like I must be oversimplifying but I can't find any inconsistencies in my model.

> But we don't ever get the result of our query - we never know the true answer to the problems facing society.

Our brains aren't designed to solve societal problems. Why should they be? They are designed to solve our own problems. The answers our brains give us are meant to benefit us. They may benefit society at large tangentially, but that is not the intent, nor should it be.
That's not possible. If you use the internet a little bit, you are almost constantly required to chose more and more new passwords. To newspapers sites to comment, to registration forms, to buy tickets to some concert, etc etc. You cannot use different password for each of them. And password systems are overkill for most people (certainly is for me).

Really, what IS sensible is having sensitive sites with different passwords and "who cares" sites with simillar ones. As the author actally says in the end of the article.
Apple has a problem - too much cash on hand.

Yes, yes, "It's a great problem to have."

But only if you are an actual person.

However, Apple is a publicly traded company and different logic applies and none of the alternatives are good.

So long as Apple holds the cash, there is the implication that they lack a long term strategy in which they are confident enough to invest a large sum of money.

Conversely, if they can't spend that much cash expanding their business without announcing their plans prior to product role out unless they use it for acquisition.

The problem with acquisition is finding a plausible candidate valued at $50-$100 billion, and it is highly unlikely they can quickly buy a portfolio of smaller companies large enough to make a dent in their cash without significant risk of public failure inherent in a bad purchase.

As for paying a dividend, that suggests a lack of vision and long term strategy even more strongly than any of the other alternatives.

A large amount of cash on hand of course isn't the worst problem a company can have, but it suggest a certain degree of inertia.

One of the main reasons the teenagers I know are possibly considering using Google+ over Facebook is because Google+ isn't blocked by our school web filter yet :P

(They can get around it on their personal devices with proxies, but the computers owned by the school are pretty well locked down)

I honestly don't think Google+ will ever have more traction than Facebook, at least with the teenage crowd.
All of us are using imperfect heuristics to select good content to read. Just the fact that we're reading HN instead of some other source right now is an imperfect heuristic. There's just too much potential reading for anyone to read everything equally.
In my own interactions with RMS he has not been totally nice (he once asked me about releasing one of my old Springer-Verlag Lisp books under the FSF doc license, I did not have the original files, I didn't want to type in the book myself, and he seemed testy) but I feel like defending him.

RMS has done a lot in the past to make my life as a developer much better. Some irony, typing this on my MacBook: I think that we are going to lose a lot of freedoms in the future: controlled computer hardware, loss of open media, loss of open internet, ...., the list goes on...

Logically, we should all be throwing our support behing FSF, EFF, some of the few rational political movements supporting personal freedom, etc. because once the tipping point is reached where we lose freedoms, it is likely we will not get them back.

I am an older hacker (60) and you may disagree with me and my world view, but just take a look at history to see cases when people did not stand up for their rights and lost them.

So, a tip of the hat to RMS, and thanks to him.

Search this ArchLinux thread, lots of great tips: https://bbs.archlinux.org/viewtopic.php?id=97375

"o" or ":open" plus a url, "t" or ":tabopen" plus a url. "d" closes a tab. Press tab to autocomplete. "B" to add a bookmark. "H"\"L", back\forward in history. To perform a search, simply start your open or tabopen command with "google " or "duckduckgo " etc. If you are on a site that uses javascript keyboard controls, press CTRL-Z to enter pass through mode. ":wq" saves your session (pages that are open will be reloaded next time) and quits.

I actually considered posting this idea just now too, but since you did, I don't have to.

A javascript +/- button to collapse and expand threads would be perfect. The indentation is just too subtle, and it's too hard to follow the thread in bigger discussions (which are often the good ones worth following).

Somewhat unrelatedly, I would think that comments should get extra points if they spawn a lot of discussion. I mean, that's what the points are for, right? This would credit the original user's karma for fulfilling the goal of the site, but more importantly, it will bump up the entire discussion higher on the page to better reflect it's value. (Though I don't know the algorithm that orders comments, so that part may already happen)
I'd submit that it's less like caching than it is rooting for your favorite sport team.

In the current context, how else to explain liberals justifying Obama's policies WRT the financial sector, or Republicans vilifying his healthcare bill? Ask both groups of people about those policies 4 years ago, in the absence of names and faces, and you'd get very different answers. And don't even get me started on "I'm either ok with or stridently oppose deficit spending".

That's the opposite of caching, it's tribe-based fist-pumping.
Yes, I agree. But it's really not the same. Think about steve yegge and his posting on google+. We cannot rely on anonymity across a board when user error is such a likely possibility. While it's easy and intuitive to correctly post when sober and clear minded, certain things may slip your mind. Steve yegge also intended for only a select group of users to read it. Let's pretend that he had full anonymity. There wouldn't have been any hesitation in posting. No immediate deletion. And no backlash or grief from his readers.
Thanks for this. I knew first Gen could be updated, but didn't know the latest could be. This now makes my decision hard again: performance or weight? sigh
>The solution here is to create context isolation - which is very easy to do with anonymity.

Not the best solution. I in fact has been saying the illusion that people are perfect is fundamentally flawed for a while now.
This is true.

Camera matching usually requires a lot of forethought and preparation of the physical scene, involving thoroughly surveying the location & obtaining light-probe data so that an accurate 3d model of the scene can be produced and the inserted objects lit correctly.

This could make composing 3d/practical images a trivial exercise, very nice.
I am not at all a Groupon apologist (I think their base business is declining and doesn't make sense for most local businesses in the long-term), but you have gone way overboard by comparing Groupon to boo, webvan, and kozmo.

For all its faults, Groupon is on track for $1.5Bn in NET revenues (this doesn't include pass-through that they initially included in revenues) this year, and will probably still IPO somewhere around 10 billion dollars. All of the companies you mentioned only existed for 2 years before being liquidated.

As for everyone in the valley knowing Groupon was a ponzi scheme for the past year and a half - then the folks from Battery, Accel, Kleiner Perkins, Greylock, NEA, TCV, Silver Lake, etc (all of whom made investments in Groupon this year) would have to be complete idiots to invest in Groupon, and that is certainly not true.
