Mayer is definitely a techie. However, she is aiming to conquer the world of social status (which has its own rules which cannot be broken)[1].

> But then, one Friday night in mid-April, Mayer was eating a bowl of pasta in her dorm room and scanning her email when she spotted a message slugged, “Work at Google?” Just as she was about to hit delete—her reflexive response to new recruiting pitches—she leaned over and inadvertently hit the space bar key, opening the email. As she read, she remembered a conversation she’d had in the fall with her mentor, computer science teacher Eric Roberts.

She had just returned from nine months in Zurich, Switzerland, where she was working with 30 other researchers to build a recommender system for the web, similar to the one Amazon uses to suggest books based on a customer’s previous purchases. As Mayer talked to Roberts in his office, he nodded and pointed upward. “There are two guys on the fourth floor who are building what you built,” he said. He apologized for not being able to remember specifics about the company they were forming, except that it had a funny name, but he thought maybe she should get in touch.

...

> The following afternoon, Mayer was interviewed first by Amit Patel, the company’s eighth employee. His opening words to her were, “I’m not sure I’m able to interview you, as I started this morning and I don’t know what we do yet.” He eventually posed a number of general computer science questions about the way memory is allocated in different programs.

Response to Sam Odio
I hope they're not serious. Scanned it and realized they wrote the questions off the top of their head. Incorrectly.

Question 5, Given the following code, what is the value of e.ID?

Well, they're right that it won't compile, but not for the reasons given. First it's gonna choke on the missing semicolon in the Person constructor:

Person()
{
FirstName="";
LastName=""
}

Then, before it gets to the line they claim is problematic, it'll choke again, the Person constructor is private so you can't access it from Employee.

Question 9, what is wrong with the following code.

This isn't a property and won't compile:

public Size Size
{
return new Size(i,j);
}

Correct:

public Size Size
{
get { return new Size(i,j); }
}

Also, it's from 2007.

Edit: fixed spacing etc.

Anonymous defaces BART website & releases user info
The text is so small I have to zoom in 3 times to get it the same size as Google with no zoom. I was too distracted by that to attempt to read anything. The only button on the page is a Facebook login that requires access to every bit of data in my account. I passed on that.
I'm must say. It's a terrible article, it leads you on like a drunk college girl, just to be left in the dumps a page later.

Where is the "this is what happened" part? Why make the reader think that the photographer was thrown in jail? Why not just come right out and say:

Photographer questioned on-site regarding the photographing of a refinery. Photographer feels molested, but is actually quite fine. Laws about questioning photographers about photographing uncommon places are too broad and rely on the officers own interpretation of esthetic. Something should be done.

Tada.
Unfortunately it's a lot of smaller charts and they're embedded in an SVG based diagram interface as foreignObjects, which doesn't support a WebGL context (in Chrome at least). I'd love to play with WebGL, but not usable for this task.

Writing the whole interface in a WebGL canvas could be really fun, but far too much work for an MVP, and would kind of mess with making it work on iPad etc.

Seconding a call for a YouTube video. On Chrome 13, Windows 7, with a nVidia GeForce Go 7600 with the latest driver and OpenGL 2.1.2, and I get the error:

Vertex shader sampler count exceeds MAX_VERTEX_TEXTURE_IMAGE_UNITS (0).

You might laugh at my hardware, but from my own OpenGL work I know the majority of users out there have crappy old chips or god-awful Intel graphics chips which the vendors can't be bothered to support any more with decent drivers that support the latest OpenGL features. Most people don't surf with a gaming grade GPU. If WebGL is this fussy about hardware, it could severely limit its uptake.

According to https://developer.mozilla.org/en/WebGL#Gecko_6.0_notes OES_texture_float was added in Firefox 6. This is strange, though, because IIRC the path tracing demo that was posted recently used floating point textures, though perhaps through a different means (I'm not familiar with how extensions and texture formats work in WebGL).

Edit: I just got the demo to work in Chrome, and it says that, at least for caustics, OES_standard_derivatives is also required.

the core vale prop is good: why print 10 million pieces of mail in Calif. to deliver to St. Louis when you can have a computer in St. Louis do the mail merge and save literally a ton of freight?

At first glance it may make sense to have mail originate from twenty proximate, regional post offices, rather than one point in California. There are scale issues here though, and believe me, nowhere but the print shop are your costs so affected by scale - it is the #1 factor by a long shot. Printing 10 million pieces in one place then mailing around the country, surprisingly, is very often cheaper than printing 500,000 pieces in 20 places despite not having to mail the stuff as far.
Maybe you have a graphics driver that's been black listed, so you're falling back to software? Try Googling for steps to override the WebGL driver blacklist in Firefox and Chrome (probably a command-line flag, about:flags, or about:config setting).
What law? The article refers to a "special order" of the LAPD which directs the officers to question photographers, but doesn't mention any laws as far as I can see.
Added myself, but thought twice about giving you access to my Facebook stuff, so revoked the FB app stuff again. You don't need to access my FB account, period.
Thank you for clarifying; however, as I was quoting directly from the linked article, in paragraph six (the ellipses I added did not change the meaning of the sentence noticeably), not from the actual policy, I think that you might be better served to call the article out as not accurately representing the policy rather than to call people out for taking the article at face value.

It reminds me also how clojure has recur, for tail-calls, rather than rely on the user to write code that would do so, which started as limitation of what the Java VM could do, but now it turns out that this design is better - as the intention is - make sure that the code is tail-call recursive, rather than relying on programmer or compiler to do it right.

In the same spirit - & rather than % for that example.

Another famous experiment that supports the finding that people are hyper-sensitive toward cheating:

http://en.wikipedia.org/wiki/Wason_selection_task#Policing_s...

This experimental evidence supports the hypothesis that a Wason task proves to be easier if the rule to be tested is one of social exchange (in order to receive benefit X you need to fulfill condition Y) and the subject is asked to police the rule, but is more difficult otherwise. Such a distinction, if empirically borne out, would support the contention of evolutionary psychologists that certain features of human psychology may be mechanisms that have evolved, through natural selection, to solve specific problems of social interaction, rather than expressions of general intelligence. In this case, the module is described as a specialized cheater-detection module.

That's the point of the game isn't it? To determine if people will irrationally pay to punish a cheater for the sake of revenge? At least that's what I got from the article.

What specific law are you referring to? A police department's general orders are not laws. They're directives to the police, and they're confined to those powers already lawfully conferred to the police. A department's general orders cannot meaningfully include things like "arrest photographers on sight".

Manifesto of the appalled economists
My gut feeling is that it's hard to see how this can be efficient on a large scale. The 10% water is impressive, but it's weighed against:

- cost of climate control for the growing areas

- cost of electricity, for the artificial light and all the gadgetry needed to keep it running

> And this is why I'm writing a programming language that isn't turing complete.

That would not be a particularly new idea. One example is SQL, that makes searching through the data structures of an database much simpler than it would be if a general purpose language was used. Now SQL has been extended to be touring complete, but is not typically used that way.
Please assume good faith. My question is, "Is it more likely that natural selection didn't find the apoptotic strategy, or that the apoptotic strategy wasn't a net win, in the environment in which the natural selection happened?"

So let's try to get a handle on which it is likely to be.

The Time article says:

> To fight infection, human cells have proteins that attach to dsRNA and trigger a cascade of reactions that stop viruses from copying themselves.

So, what we observe is:
- Human cells have a mechanism to detect dsRNA; - Human cells have a set of countermeasures that they can produce to block viral replication;
- Human cells have a mechanism to produce those countermeasures when dsRNA is detected (and I'll give you good odds that they have other ways of detecting viral infections that also activate the countermeasures);
- Human cells also have an apoptosis pathway (which, as it turns out, the cell is not shy about activating in other circumstances, like if too much DNA damage is detected)

One of the following must be true

(1) All of the existing machinery (dsRNA detection, existing countermeasures, and the linkage between the detector and the countermeasures), taken together, must be much simpler than this little transducer they engineered that connects the existing dsRNA detection signal to the existing apoptosis pathway, so that X years of natural selection was likely to find the existing machinery but unlikely to come up with this new solution
(2) Blindly triggering apoptosis when you detect dsRNA is not the way to maximize the amount of sex your children have
(3) The only reason viruses exist, and plague mankind, is that we got incredibly unlucky

My money's on (2). (1) seems unlikely because it seems like you have to search a much larger space of DNA base pairs to find this whole complex of dsRNA detectors and virus replication inhibitors, than to find this transducer. (3) is unlikely a priori.

So, what would explain (2)? Like I said, several options:

(A) The drug isn't valuable in practice (the cure ends up being worse than the disease)
(B) The drug is valuable but has a lot of side effects, so taking it all the time is bad. You only want to take it when you have a really nasty viral infections. The machinery to detect the correct case in a cell is too hard, but now that we have brains, doctors, and the internet, we can make a better decision than a cell could about when dsRNA should be connected to apoptosis than a cell could.
(C) Having the linkage was a bad idea for most of the history of mammals, but is a good idea for humans today. Maybe we used to have a lot of immune resistance that we no longer have because of our super clean environment. Maybe we have better nutrition and that somehow makes speculative apoptosis hurt less. Maybe viruses are more dangerous in the dense urban environments where we now live. Maybe it's a bad idea for young people, but a good idea for old people.

These all seem possible to me.
Let me think...

Total solar irradiance on earth = 1.336 kW/m2
Leds @ 15% efficiency = 8.9kW/m2

8 weeks * 7 days * 12 hours * 8.9 kW = 5.9mWh

I'm surprised that the article, while otherwise well-researched, doesn't even mention the Zahavi Handicap Principle.

In Zahavi's view, altruism is a form of signalling: the altruist is doing so well, they can afford to lose a good deal of material benefits. The altruist then benefits from the high regard of the peers who witnessed the facts (e.g. potential partners of the opposite sex).

From this perspective, the crucial step in the experiments presented is not the punishment, but the subsequent public exposure of the in-game behavior.
This is exactly correct, assuming you're printing offset rather than digitally (e.g. on an Indigo.) Offset printing has tremendous economies of scale, making it FAR cheaper in most cases to print once and drop ship to various SCFs than to print multiple times.

The article you're quoting links directly to the LAPD SAR, where the surrounding context (literally in the same sentence) to your "hours of operation" quote makes it obvious that your "found an interesting business" proposition isn't implicated.

The article quoted the SAR out of context, and not only did you perpetuate that bad quote, but you actually amplified it by making up a narrative to go with it.

The original text of the article is no defense for intellectual laziness or dishonesty.
> In soccer diving is not punished if the referee doesn’t see it, even if three TV cameras captured every detail. Are soccer fans wrong in being disgusted by such diving?

So why do they keep letting players do that? Are they requested not to do that? If so, then it is slightly different from Sam's situation. It would be similar if Jonathan had requested people not to do what Sam did. Not punished != not a rule.

> There is no law against slamming the door close before the person behind you can enter. Are people wrong in believing that such behavior is rude?

You shouldn't assume such behavior has ill intentions. If you don't like it, ask the person to stop doing it. Then and only then if he/she keeps doing it, you can call him an asshole.

Someone is not an asshole simply for doing something you don't like. You have to dig into the intentions.
Building my first startup - Day #0
Hardware compatibility is the least of WebGL's problems. Right now there's essentially zero chance of WebGL powering any modern graphics engine. It unfortunately seems doomed to a life of "hey-look-at-my-cool-effect". (Which is neat, don't get me wrong. But it will never reach Doom 3 quality, and that's a tragedy IMO.)

Example: WebGL doesn't even support compressed textures. The spec actually mandates "We will not support compressed textures, and this is by design". Facepalm...
