Snowden did a good job, but now it is time for him to leave Russia.
Good news (in Dutch), about Dutch organisations for scientific research no longer only looking at the number of published papers as a measure for scientific quality.
The future of science is at stake.
The NSA builds a quantum computer in order to crack encryption keys.
Hackers now sell full access to a 300.000 Euro bank account for 300 Euro, says the BBC. The factor 1000 between the two must be the value of all the institutions (law enforcement, governmental supervision, juridical embedding, etc.) involved in traditional banking. Bad news for bitcoin.
Peter Higgs says: "Today I wouldn't get an academic job. It's as simple as that. I don't think I would be regarded as productive enough." Without Higgs we would not have had the Higgs boson blues.
A truly brilliant case of "social software engineering": bitcoin. However, the (informal) proof of incentive compatibility of the mining protocol seems to presuppose honesty of the miners, which would mean it is circular.
