Here's the wikipedia page on it: http://en.wikipedia.org/wiki/Gravity_Probe_B

One point about it is that the probe had a lot of noise, so much noise that it swamped the signal. It was only by developing computer models of the source of the noise, and then subtracting it from the signal that the result was found.

But I find such "adjustments" distasteful. I mean everyone expects a certain answer, and voilà you get that answer. Is there a bug in your code? Or course not - you got the expected answer didn't you?

(See the section called "NASA review" in the wikipedia article.)

Anyway, now that they learned so much about such probes they should launch another one and get much cleaner data.

I rewrote the tagline earlier today, I'll take that as positive feedback. :)

A catalyst speeds up a reaction, sometimes essentially so. The coming education revolution is going to be much larger than any single organization but we think we can help bring it about a little bit quicker. Sal Khan is definitely a catalyst in this respect.

We do this through two complimentary features sets:

1) Learning about learning. These are tools to track student progress, judge the effectiveness of different techniques, etc... Think an education effectiveness dashboard. By providing high-quality information we can shorten and improve the feedback loop by better understanding what works and what doesn't.

2) Online learning delivery. As a starting point, think an LMS like Instructure/Moodle/Blackboard, etc... but designed to work with the previous point - try new things and measure. The key here is enabling teacher creativity. It's all well and fine for us to implement and measure new tools in house but that's not fast enough (and gives us no particular advantage). The Instructors on our system need to be able to easily implement their own thoughts on how to improve teaching (and then see the results). They are much smarter than we will ever be about this. We need our instructors to see this 'LMS' as their playground for teaching experimentation. And, of course, when one of them makes a breakthrough they will share it and everyone will be better off.

Innovation is experimentation that results in an improvement. We help teachers experiment and judge the success of their experiments, shortening the feedback loop and increasing the rate of innovation. This is what we mean by "be a catalyst".
I am not sure that Marc Andreessen has so much influence at Facebook. He has one of the 3 board seats that are controlled by Zuckerberg. And Skype would be Facebook's biggest acquisition so far, so it wouldn't be easy for him to convince Zuckerberg to do it.

Why would it take three times longer? I do produce my HTML manually, but that does not mean I type every single character in the code by hand. Snippets, Zen-coding/Sparkup, autocomplete, etc.—all this allows to produce HTML fast, efficiently and avoid syntax errors.
So is he dead? If you don't have someone's DNA, how does a sister's DNA prove you are the one dead? It could have been a brother. It's not that I really don't believe it, just why don't they show the proof? A photo can be photoshopped, but everyone knows it when it is. We aren't babies to be coddled, we saw the first photo and no one freaked out. Before we knew it was fake. Even the Muslims who still liked him were like, "yawn". So show it. Prove it. Why are we always having to ask Obama for proof of everything. This isn't about him and he shouldn't make it that way again.
Facebook may make $2B in profits this year. So I think they could come up with this cash. Also, they can give some of this amount in stock.

What a desolate, barren worldview materialism is!

In your view, wisdom is an illusion. So is peace. Are not these just specific neurotransmitter configurations? Nothing more. The only 'wisdom' that makes sense according to materialism is: "Eat, drink and be merry, for tomorrow we die!" The only peace that can be gained from materialism is not acceptance of, but numbness to, the absolute vanity of existence and the absence of anything that transcends the merely physical.

Interesting, it isn't prompting me to do any such thing.

Anyway, since many are mentioning 1Password - I used that for a couple years and switched to lastpass, because I was tired of having to install plugins across all the browsers on a platform and then having to find workarounds with Dropbox for syncing on additional machines and the lack of a Windows client, when I'm stuck working on Windows.

Also, since I use two-factor authentication, I wonder if that's the reason they have not asked me to change my password?
Interesting story of the two Aérospatiale Lama world records:

"On 21 June 1972 a Lama with a single pilot (Jean Boulet) aboard established a helicopter absolute altitude record of 12,442 m (40,814 ft), immediately followed by an inadvertent record for the longest ever autorotation when the engine flamed out at the peak altitude of the flight."

(from wikipedia)

Always reminds me of the saying: "there are no good helicopter pilots, there are only old helicopter pilots".

There is no reason why time of the day, temperature outside, whether Obama made a joke or not, etc can't all be features for a classifier to learn.

I love the idea of an algorithm anticipating my next move and I'd argue that for the vast majority of people you can find repeating patterns that are almost always relevant. These patterns will not be simple or obvious and as you currently pointed out, the lack of data is what is holding most innovation behind. I feel that companies that own the data like Amazon will have a lot to gain if they do a Netflix-style competition to improve their recommendations engine.

I don't see many reasons for Facebook to buy Skype:

1) Technology: Skype's core technology is their P2P technology. They have their own clients for PCs and mobiles. Facebook resides in the cloud, and it works from the browser. This is a huge difference on PCs/Macs, but less so on mobiles, where Facebook also has apps.

2) Price: At $3-4Bn Skype would be by far Facebook's biggest acquisition, as all the others have been under $100M. As they don't have the amount of cash that public companies like AAPL, GOOG or MSFT have (at least not yet), it's quite a big effort for them. There need be a lot of synergies to justify paying this kind of money.

3) Culture: Skype is older than Facebook, and has European roots. Facebook has so far made small acquisitions (more like acqhiring), they don't have any experience with integrating a big company like Skype.

4) Business model: Skype is going for the enterprise market (see the appointment of the new CEO last autumn), and selling subscriptions. Facebook is going for consumers, and selling ads.

Overall, I think a better option for Skype would be an IPO, a telco acquisition, or maybe a Google acquisition.
Negative, LastPass can generate one-time passwords which you can then use on computers you suspect to be insecure.

Some of this has to do with how you define success. For dating, in the Quora said someone said "well Grindr is doing well". They have traction, in a niche community (m4m) but I'm not aware of any revenues.

The sales-pitch of these "Programming tools for non-programmer's" is usually that all of the developers at your company are busy and you need to get something done so you can do it yourself.

The problem is that the type of apps you can build are usually pretty narrow- and if your needs fall outside of that then you are screwed.

My Philips 9404H has a "movie mode" which tones down the colors (contrast), switches to 24p where available and turns off all smoothing. It's set to be activated automatically on my Xtreamer and Blu-Ray, and the local-dimming LED's provide deeper blacks.

I don't need a plasma for that.
Even if we accept the very dubious premise that Bing411 was motivated entirely by a misunderstanding of Google's aims for Goog411, so what?

Really not the best vehicle for your moral.

Your new TV only ruins them if it's running with the 120hz or 240hz smoothing interpolation turned on. Chances are, you turned that off as soon as you set your television up, just like I did.

There's no question that 24fps film looks awful using these gimmicks. The real question is will film running at a higher rate (like 48fps) will also look bad? I know that the show The Event seems to be filmed at a higher frame rate (it looks like it was filmed in Video rather than Film) and it is disconcerting to watch. It actually makes the acting look bad, which I don't think it would otherwise seem.

However, like 3D, it's now a gimmick that it is included on so many sets that you almost have to go out of your way to avoid buying one that has them.
Yes, there are mistakes in the details, but the actual points are valid. Default comparison behaviour is error-prone, operator overloading is badly designed, and the subscriber-less events exceptions are a kludge.
He's not arguing that 24fps is the only good way to make movies, he's arguing that the only good way to render movies previously shot at 24fps is by using a n*24Hz refresh rate.
> let's assume it's about 1mm per pico-second (3 times that of vacuum).

If Intel had found a way of making signals propagate three times faster than the speed of light in vacuum, everyone would be too busy rewriting the laws of physics to take notice of their transistor technology improvements.

A 3mm path-length difference would be more like 10ps; 20ps for a 2x3mm round trip.

(But I bet Intel take a lot of trouble to reduce those distances. There probably isn't anything that has to happen in a single cycle that involves 6mm-worth of propagation delays.)
Computer Science != Programming

I know more than a few Computer Science majors who are much smarter than me (I didn't do CS) and know their stuff down cold but couldn't program their way out of a paper bag.

Maybe Sal can - dude can do pretty much everything else - so he almost certainly can do those videos, but there's still a distinction there, between the two.
I also don't really buy that answer, but I think it's partly because many businesspeople already do do their own programming, in Excel, a good-enough solution that also has the critical edge of being installed on most corporate machines. There are thousands of people who don't consider themselves programmers who do all kinds of what amounts to dataflow programming in Excel, ranging from quick scripts that automate repetitive tasks (what Unix folk might use a shell or Perl script for), to full-on modeling and simulation.

This sounds exactly like the release we got from Sony a few weeks ago, detailing the points of entry, the volumes of data released from their servers, and estimates about who is and isn't affected. And who can forget when Sony told us all exactly what steps they were taking to make sure this wouldn't happen again?

DRM and the eBook Future
I'm not sure how the amount of data is very related to the importance of the settings on your TV. Now, of course, all these things are sort of ephemeral, so it is pretty difficult to quantify their effect on the viewing experience, but the article brought up two different settings on TVs that have bad defaults.

1. Color. As the images in the article show, changing the color profile makes a real difference in how you see the movie. Color can set the tone in a movie very effectively, so when it is wrong by the amount seen above, I think it can have a tangible effect on how you see the movie. Home video may carry a lot less information than film, but I've met people who work on color and an enormous amount of effort goes into making the colors look good on TVs and computer etc.

2. Smoothing. It is possible that TV's have gotten better at this, but I have watched movies with pretty aggressive interpolation on and it is jarring. It is a common reaction to feel like the movie has been soap opera'd, but more importantly, panning shots often seem strange because everything moves on screen a little differently than you expect. At least one other commenter in this thread says that they have gotten used to the smoothing effect, so it is possible that over time this will have less of a negative impact than it does now. But I do believe that the best filmmakers understand their medium well and that interpolating does more harm than simply losing 99% of the information to deliver the movie on Blu-Ray.

Anyway, I agree that without changing your defaults you could live a long and happy life watching movies without missing too much. But, my main take away is that no one wants the default settings on your TV except the TV companies. It is trivially easy to make your TV better by changing two settings, and it is a crying shame that the defaults picked by the manufacturers are bad.
shh... don't blow my strategy
Pi would still be fundamental in mathematics whatever the geometry of our universe. (Examples of where it would turn up: consider the differential equation f''=-f; all its solutions are periodic with period 2pi. The series 1-1/3+1/5-1/7... has sum pi/4. The series 1+1/4+1/9+1/16+... has sum pi^2/6. exp(pi sqrt(163)) is ridiculously close to being an integer. There are deep reasons for all these things, and they wouldn't go away if the universe were very far from spatially flat.)
