OK, here's a site with an interview with IDEO's designer. It has the key pictures without the UI from hell.

This is the Eric Schmidt vision of the future. People will still go to offices and have meetings. They'll just have better cars and presentation tools, and better delivery services for physical stuff.

Will we really need that many office workers? That's the huge question. Given the head counts at newer companies, probably not.

Comment Importance (Score 3, Interesting) 96

There is a great interview with Elon Musk on youtube here. He is remarkably transparent about his reasoning. One key to his success is that he works very hard to understand motive and purpose when making decisions.

Musk makes that point that it costs about as much to fuel a rocket as it does to fuel a 747. Space launches are mostly so expensive because the vehicle is sacrificed with each launch, not because of the energy requirements for a space launch. The other big component of the expense is that rocket manufacturers charge a lot. According to Musk the value of the raw materials from which they are formed is reasonably inexpensive. Those were two hugely important realizations because they meant that space launches were not inherently expensive and therefore there is enormous potential for reducing launch costs.

By being Space X instead of Boeing the cost of launch is reduced to about 25% of conventional launches because Space X can assemble a rocket from raw materials for that much less. A re-usable vehicle, Musk predicts, would reduce launch costs by an order of magnitude.

So those are the motives and reasoning underlying the X-wing grid fins and re-entry discussed in the Slashdot summary.

Comment When cars are self-driving and shared (Score 1) 454

...they'll all be owned by Uber.

There's a network effect for shared vehicles. Availablility is best if you have one big pool of cars rather than lots of little ones. So there will be a single winner in that space for each city.

Imagine Uber having the power of GM and Google combined. Run by the current team of assholes.

Comment Re:Amazon Elastic Cloud? (Score 1) 247

decades ago, Cray Computers were assembled by people (housewives) who were allowed to spend no more time than they could be maximally effective in, using wires cut to millimeter-precise lengths.

Yes, and there's a Cray I at the Computer Museum here in Silicon Valley, upholstered base and all. You can sit on it if you like. It's not useful for much else.

All modern supercomputers are composed of a large number of microprocessors. The interconnects are faster than with ordinary hosting/cloud operations, but the CPUs are the same. The biggest supercomputer in the world, in China, is 3,120,000 cores of Intel Xeons, running at 2.2GHz each.

The question is whether the problem you're solving needs tight interconnection. If not, you can run it on a large number of ordinary computers. Weather may not be that tightly coupled; propagation time in air is kind of slow.

Comment They'll be replaced by robots soon. (Score 1) 496

Don't worry, most of those jobs will go away soon. Amazon's newer warehouses use Kiva robots to move merchandise around to picking stations. Picking is still manual; the computers do all the thinking, the humans just pick up what the laser pointer points at. But Bezos owns a robotics startup working on automating that. At Amazon, being replaced by robots isn't a future problem. It's here now.

Customer service is already mostly automated. It's can't be long until customer service chat is with a computer, not a human. Then Amazon will need fewer people.

Comment Re:That is not what the halting problem say (Score 2) 335

Mod parent up.

That's correct. The best known demonstration of this is the Microsoft Static Driver Verifier, which every signed driver since Windows 7 has passed. It's a proof of correctness system which checks drivers for buffer overflows, bad pointers, and bad parameters to the APIs drivers use. It works by symbolically tracing through the program, forking off a sub-analysis at each branch point. It can be slow, but it works.

Microsoft Research reports that in about 5% of the cases, the Verifier cannot reach a decision. It can't find a bug, but it can't demonstrate the lack of one either. After 45 minutes of case analysis it gives up.

If your driver is such a mess that it's anywhere near undecidable, it's broken. Those drivers get rewritten with a less ambiguous design, usually by adding more run-time checks. Problem solved.

(Remember when driver bugs crashed Windows all the time? Notice that's not happening any more? That's why.)

Comment How much longer will Foxconn need Apple? (Score 4, Interesting) 109

This is the problem with outsourcing manufacturing and keeping the "brand". Eventually, if they're good, the outsourcing company takes over. It's about time for this to happen to Apple. The hardware is approaching maturity. The last rev of the iPhone was only a minor change over the previous one, and the technology was comparable to HTC's product of two years ago.
