You think Facebook did market research before starting up?

Yes, basically. According to the movie, Zuckerburg copied another in-development app, one that was likely to be successful. And being at the school he saw a need that he carefully wrote his app to fill.

"Market research" doesn't need to be charts and surveys; if you know your field well enough you can generate good ideas.

I suspect cheap and huge computers had a large effect too. I haven't done a 3D print, but the app that slices an object for printing and plans the head path probably takes a significant amount of CPU and RAM. The printer could easily have been built in the 80s, but only recently have home computers become powerful enough to drive them.

My camera-nerd friend loves the new Sony a7s, as it's optimized for video. Considerably less expensive than this.

If I were to hack an image sensor, I'd work on phone cameras. At this price range, I expect the thing to be awesome out of the box, so "open source" doesn't really add anything.

So that just means the project is not for me. I hope it's successful regardless, but I suspect it's much cooler for the inventor than it will be for the users.

I agree with most of your post, but this is simply false. USB 3.0 is a completely new interface, bolted on USB 1/2 to make it seem like a seamless transition.

I've been wondering about that -- Since a USB 3 port has separate pins for ultra-speed and high-speed, shouldn't I be able to plug two devices into the same port?

But if the claimant doesn't have any copyright authority, I don't believe the claim is actionable under the DMCA. If I claim your video violates someone's copyright, YouTube is under no obligation. If I claim the video violates my copyright, only then is YouTube obligated to take down the video. And this triggers the perjury clause.

20/20 is the ability to read things made of lines 1 arc-minute thick. If the letters are smaller, you might not be able to read them, but you can tell tell it's text because the rods and cones are much more dense than that. "General colored images" usually have texture.

Another big value that's not discussed often is that the higher the resolution, the harder the pixels are to see. This is why even 480i content looks better on an HD TV -- it's a much smoother, cleaner picture. Also, through some quirk of physics, when my eyes de-focus I can see pixels.

There's two advantages to silly numbers of megapixels on a phone. One is that there's no room for a zoom lens on a phone, so the more pixels your sensor has, the more useful digital zoom becomes.

The second is that us nerds buying high-megapixel senors funds research and development of high-megapixel sensors, eventually making them cheap enough that something like the Lytro light-field camera becomes possible on a phone.

By ordering low-end GPU, you annoy everyone -- the users have to put up with crappy chips, IT has to support more complex systems, and budgeting has to pay for chips noone wants. So instead, order most of the laptops without discrete GPU to save a few bucks. Then order a few with high-end GPU for the few people who want them.

No actually, a dash-mounted tablet (or phone) is not legal unless it is not "operating" (term is not defined), or it has explicit interlocks to prevent app and video operation while driving. IANAL, but the only way I can find to legally use your phone as a GPS is to install it facing away from the driver, and use it only in voice mode.

Just go with the flow control, roll with the crunches, and, when you get a prompt, type like hell.
