+ - SPARC accuses SparkFun for trademark infringement->

Submitted by isnoop
isnoop writes:, an electronic components distributor has received a cease and desist letter from SPARC International, Inc. claiming "Because the dominant portion of the SparkFun mark, namely, SPARK, is phonetically identical and nearly visually identical to SI's SPARC mark, and because it is used in connection with identical goods, we believe confusion is likely to occur among the relevant purchasing group."

US Navy Tries To Turn Seawater Into Jet Fuel 402 402

Posted by samzenpus
from the ocean-in-the-tank dept.
Hugh Pickens writes "New Scientist reports that, faced with global warming and potential oil shortages, the US Navy is experimenting with making jet fuel from seawater by processing seawater into unsaturated short-chain hydrocarbons that with further refining could be made into kerosene-based jet fuel. The process involves extracting carbon dioxide dissolved in the water and combining it with hydrogen — obtained by splitting water molecules using electricity — to make a hydrocarbon fuel, a variant of a chemical reaction called the Fischer-Tropsch process, which is used commercially to produce a gasoline-like hydrocarbon fuel from syngas, a mixture of carbon monoxide and hydrogen often derived from coal. The Navy team have been experimenting to find out how to steer the CO2-producing process away from producing unwanted methane by finding a different catalyst than the usual one based on cobalt. 'The idea of using CO2 as a carbon source is appealing,' says Philip Jessop, a chemist at Queen's University adding that to make a jet fuel that is properly 'green,' the energy-intensive electrolysis that produces the hydrogen will need to use a carbon-neutral energy source; and the complex multi-step process will always consume significantly more energy than the fuel it produces could yield. 'It's a lot more complicated than it at first looks.'"

I used to use an app that did precisely this on my previous Windows smartphone. It didn't use GPS data but allowed locations to be defined based on tower codes and relative strengths.

The iPhone could have this as well if you could run background apps and access the network stack without jailbreaking.

Audi and several other car makers do this to a lesser extent. If you want the "performance tuned" car computer software, you can go to a dealer and spend several hundred dollars to have them flip a switch.

You can enable a trial version of this performance tuning on your own that automatically disables after X miles.


+ - Cryptographic Key Rotation Solutions?->

isnoop writes: "As part of a search for an ideal key-rotation approach, I've begun to wonder if there is an encryption method that would allow generation of more than one key that can be used to decrypt the same encrypted string. That key could then be split in two between the data storage machine and the data requesters, with the power on the side of the storage machine to revoke its half of the key at any time. This way, multiple keys could be used and revoked, but the underlying data would never have to be re-encrypted.

One possible solution could be a public/private key algorithm where multiple public keys can be generated for the same private key. The public keys could then be split and used as described.

Does anyone have any experience with this sort of problem or know an encryption method that might fit this description?"

If they're going to start drafting computers for their PC army, they're going to have to provide some exemptions. What if my computer is a pacifist or perhaps it's owned by an Amish family...

Well, scratch that last part.

Still, when the PC draft comes, I'm shipping my computer to Canada.
