A contract with your carrier with a 'free phone' attached costs about $50 a month, so (those are usually 2 years...) cost $1200 in two years. If you get a SIM-only contract (is that possible in the US?), those are $5 to $10 a month, so you save $800+ in 2 years. Hey, that's enough to buy an Edge, right there!

+ - Quantum-Secure Authentication with a Classical Key->

Submitted by ChristW
ChristW writes: This paper describes how a quantum-secure authentication can be achieved using a (physical) key containing a PUF (Physically Uncopyable Function, consisting of a random 3D structure of nano-particles). The setup uses a low photon-count wavefront to make skimming and flooding of the system practically impossible. From one of the authors is also the paper 'Towards more aesthetic forms of cryptography', which is also a good and funny read.

Well, I live in The Netherlands, and one of the things that we witnessed the last couple of weeks was a new law proposed by the Minister of Safety and Justice (...), Ivo Opstelten. He proposed that people who have encrypted files on their computer should be pressed into giving out their keys, "but only if they are very bad criminals, like when hiding child porn or are terrorists". Oh, so, that's OK then...

AdTrap’s creators point out that their device works not only with full-sized PCs, but everything else connected to your home internet, such as Apple devices running iOS 6 – and without the need of third-party apps or jailbreaking. In addition to blocking web browser ads, AdTrap is also reported to remove ads from streaming devices like Apple TV and Google TV. A configurable “whitelist” is offered too, so that users can allow adverts on websites of their choice.

Yes, there _is_ such a thing as perfect consonance in music, but _not_ on an instrument with restricted frequency generation!

If you sing, or play a flute, or a violin, you're able to generate a much larger range of frequencies than when you play a piano. That way, you can, and should, create 'perfect consonance'. Note that this is a lot harder than 'hitting the right key on the piano'! And if you get it wrong, the beatings get annoying very quickly.

I've been told that 'the only way to get two flautists to play together nicely is to shoot one of them'.

This is now. Later is later.
