Comment: Re:If your encryption is secure, the key is the se (Score 1) 170

I believe the dns-sec root keys are an example of a key in multiple parts.

The master key can be reconstructed by combining 7 keys together.
There are 14 people that have part of the key and I believe any 7 people can be used to recreate the whole key again.

As bitcoin uses public / private key cryptography you could have clients only have the public key until you need the private key.
So the client would be able to see that someone has sent them bitcoin but not be able to use them as they do not have the key allowing a store to validate that someone has sent in the coins.

Paper wallets is one implementation of this idea, where there is a piece of paper with 2 qr codes with your public and private keys.
Give everyone your public key but when you need to send the coins somewhere you need to scan the qr code to import the key.
You could probably come up with a system requiring you to assemble the private key from several parts.

This is not running an operating system, this is in efi the replacement to your bios.
EFI can do a lot of stuff, there is a text editor, interactive shell and python interpreter so it is something that you can write programs in not just operating system boot loaders.

I have installed this as a boot entry on my laptop and it does boot directly to zork in no time

This is probably not the first human made object to reach interstellar space.
The real furthest object is a man hole cover.

During testing of nuclear weapons they were doing tests underground. They had a nuclear weapon at the bottom of a long shaft.
On top of the shaft was a metal cap.

It's not known how fast it is going or if it actually left the atmosphere but if it did survive it would have been going really fast

In the last year or so support for 3d acceleration inside a vm has been possible.

Virtual box states that it has opengl and dirext3d 8/9 support in it's release notes.

I have not needed to use it so I am not sure how it performs.

Why not scale down the LHC and build something that is capable of accelerating something relatively small say 10-100kg fast enough to make it to orbit instead of accelerating atoms to nearly the speed of light.

The problem with conventional rockets is you need to carry the fuel to get in to orbit as well as the fuel to go where you need to. The bigger the ship the more fuel you need to carry to overcome the weight of the fuel.

If you can split the carrying of fuel for your journey from getting your rocket in to orbit you would not need to waste as much fuel lifting itself.

You could set up an automated system that would fire a 10kg payload of fuel every 10 minutes and get what you need over time far cheaper than one big launch.

Wasn't there something about a PASCAL programmer knowing the value of everything and the Wirth of nothing?
