In addition to rope systems we should also use pneumatic tubes. Mail in Manhattan used to be transported across town efficiently, until GM convinced the Post Office to switch to trucks.
I also expect any day now for passenger dirigibles to make a comeback. Popular Science can't be wrong. They've been saying it since 1974.
Tollways in Dallas-Fort Worth, TX have done away with all toll booths and replaced them with cameras too. They'll mail you a bill for the tolls on a periodic basis, though you can still get a toll tag (RFID?). We don't live there but were driving on the tollways over the holidays. We have yet to receive a bill as we live out of state. So, depending on how accurate the system is, you may or may not get a bill. We'll pay it if it ever shows up.
The corn grown took fossil fuels to plant, grow, and harvest. So the energy return on investment was very low. Cellulosic ethanol is still years away. The ethanol boondoggle basically became a big giveaway to agribusiness (Cargill and ADM) and did nothing to reduce our dependence on foreign oil. The other problem is that even if we could grown all our corn organically, there would still be competition between growing crops for fuel and crops for food. We cannot put enough land under cultivation at our current consumption rate.
The only organic fuel that has the potential to replace fossil fuel on a large enough scale is biodiesel from algae. It could produce more oil per acre than almost any other plant but there are still problems to be worked out and scaled up. We'll still have to drastically change our lifestyle to live in more compact cities with greater public transportation. Even if we could go all electric with solar and wind, we still would have to use tremendous amounts of lithium and I don't there's enough in the world to make that possible.
My point is we are running into hard physical limits and to solve those problems require vast leaps in technology and energy production ability that are beyond what is even feasible with our rate of technological change. We can transition away from fossil fuels but it won't be easy and it's going to be a bumpy ride.
They'll have to rent a textbook which will expire at the end of the semester. And if for some reason you have to retake a class, you'll be forced to re-rent the book. College textbooks has always been a racket and publishers will use the new technology to extort as much money from the students as they can.
As long as Negroponte remains in charge of his baby the OLPC will never really take off. Eventually iPad technology will become cheap enough for the Third World. Too bad we have to wait for that to happen.
Life was already well established 635 million years ago. We have the stromatolites to prove it. The question should be, 'Did multi-cellular life arise twice?" Even if the Earth had been completely covered in ice, life would still have survived around volcanic vents in the oceans and in the deep rock.
I saw a mini-series called Miracle Planet and it described a still forming Earth being bombarded where not only is the ocean completely vaporized the Earth's crust was heated to sterilizing temperatures down to several kilometers and the only life that could survive that would have been deep in the crust.
There may have indeed been multiple origins of life on the early Earth. There may even be an undiscovered shadow biosphere.
Plone is one of the best CMSes on the market, but does have a learning curve. But it's fine grain security model beats Drupal and Joomla hands down. Drupal and Joomla are fine products but the don't really compete in the same space as Plone. Each CMS has it's warts. And you have to choose the right product for the end user. In some use cases Joomla and Drupal would be fine and in others PLone would work.
I've worked with all three though Plone most extensively, and it's been my experience those who reject Plone have had little experience or patience with getting up to speed. I started off with Zope and had to convert a website to a full CMS. Plone was the natural choice, but I did do a survey at the time of a lot of PHP based CMSes and none did what we needed. That was 5 years ago. There are a lot more choices available now and all those CMSes have improved over the years.
I fucking hate AT&T but not as much as Sprint. I fucking hate Apple more. I love my iPhone and I'm lucky that I can afford to pay $150/month for service (We have 2 phones w/ data).

electric golf carts advanced and road safe. Mission accomplished.
Well, I think it is doable. How many hybrid vehicles are there on the road now? I'd imagine quite a few.
Klingons have been spotted around Uranus.

On second thought who pulled this story out of their ass? Why would Apple buy Facebook? Or why would Facebook by Apple? It makes no sense.
better not be on that list.
Just reply with your login and passwords and I'll tell you how dumb they are.

Actually, I'm learning HTML5, CSS3 and JavaScript. What I want to do on mobile platforms doesn't require an app.
you should.
It's made from algae as far as you know.
Facebook is for those with low self-esteem.
Sounds painful.
only stupid people. Actually that's a stupid question. How can anything neutral be a menace?

Duck!
And some on Wall Street understood this phenomenon and exploited it. Enriching themselves while destroying the economy.
anyone?
Hey, babe wanna see my corona mass ejection?
I for one, welcome our new Martian Underlords.
