Actually they should ask the sons to get written permission from Steve Jobs before unlocking. All Apple products belong to Jobs and Jobs alone.
In my experience; it is far easier to obtain; install and work with Free Software than with Free Hardware. I asked you about this in person 2 years back; but you brushed it aside saying hardware is not trivial to copy.
Recent events have proved me right; I feel. We simply do not have access to Freedom Hardware at low cost - even the Raspberry Pi has proprietary components in its hardware.
Why can't the FSF pool resources; license technology from ARM Holdings; and build a truly Free Tablet, Free Cellphone and Free PC running Free GNU/Linux instead of the pseudo-free Android? I am sure the community will pay any money to buy truly free Hardware from the FHF.
In the above book, a Martian space elevator fails (more specifically, is induced to fail by the deliberate application of high explosives.) The result is highly destructive. The Martian equator is no longer an imaginary line, but rather a prominent physical feature.
There are plenty of scientists out there who poach free online data sets and mine them for additional findings.
And this is a good thing, despite your word "poach". Analyses which would not have occurred to the original experimenters get done, and we get more science for our money. For many big data projects (e.g. the human genome project, astronomical sky surveys), giving 'poaching' opportunities is the primary purpose of the project.
A former boss of mine once, when reviewing a paper, sent a response which was something like this:
"This paper should absolutely be published. The analysis is completely wrong, but it is a wonderful data set, and somebody will quickly publish a correct analysis once the data is available."
Now I need to stop wasting time on

I'm not comparing non-reusable rocket to reusable rocket. I'm comparing reusable rocket which returns to launch pad with reusable rocket which lands downrange of launch pad.
Other replies I have (above) say they do indeed intend to land back at the actual launch site.
Maybe the 'boost back' is just while they're developing the system, and 'land at Kennedy' is the long term plan.
OK, so I'm officially amazed.
Fuel is cheap when it is sitting in a tank on the ground. Fuel at 100 km altitude and 5km/s speed is a very different story. Fuel which you keep in stage I for 'boost back' is fuel you aren't using to put your payload into orbit, meaning you have lower maximum payload.
A parachute doesn't solve the problem of your stage being hundreds of km downrange from the launch site. A parachute can help in any of my three proposed scenarios. (I think you'd need to jettison the parachute and drop for a bit before firing the rockets, because I don't think you want to try to land while attached to or entangled in a chute. This is what Curiosity did on Mars.)
Nice idea, but they are landing something that looks like a pencil on its end. They need somewhere rock solid to put it down.
Ha! I'm going to beat him to it. I just need to steal some super-rare crystals stored at Los Alamos first, to complete my shrink ray. And a white kitten.
How does this work? The rocket will have gone far down range before the first stage separates.
* First stage reverses direction and comes back. Very fuel expensive, I'd be amazed if they're planning this.
* First stage does one 'orbit' (technically it would still be 'sub-orbital') and returns to launch site from opposite direction. Requires that the stage has sufficient energy, and requires some cross-range maneuvering unless you launch from the equator.
* Summary is incorrect, and stage landing site is not the launch site.
In any case, you really want your landing site to be in the middle of nowhere because some failure modes will result in a high energy impact.
I think Nokia has learnt from HP and Dell - threaten to release a Linux box; and you get hefty discounts on Windows OEM pricing. Even though a subsidiary of Microsoft; I guess Windows Phone 8 is a big fraction of the price of a Nokia handset - hence this crazy strategy?
but have stylistic design.
You mean like rounded corners?
I call bullshit. OpenOffice or LibreOffice can be configured to store files in
In the beginning was the word. Biblical, John 1:1. The full verse is
"In principio erat Verbum et Verbum erat apud Deum et Deus erat Verbum. "
