In February Antoine Joux produced a new record subexponential discrete logarithm algorithm running at L(1/4) speed and beating the long-standing L(1/3) mark. On June 20 a quasipolynomial algorithm was announced at the Workshop on Number-Theoretic Algorithms for Asymmetric Cryptology in France, and explained by Stephen Galbraith, and these other blogs. Lipton has not yet commented on the latest breakthrough.
Discrete logarithm and factoring are different problems but progress on one tends to lead to progress in the other. Get a paper bank statement mailed to you each month, order some paper checks, and buy stamps and envelopes for paying your bills via snail mail.

Just off the top of my head, use of this technology to 'replace passwords' has a few flaws: no information on how to register a user, what if I injure my hand, what if my palm data gets stolen, who is going to correlate palms with fingerprints, if they want my laptop do they have to also cut off my hand..."

I'm willing to bet there won't be a lot of stories about how cool it is do to science with robots as opposed to human exploration. Maybe we'll even throw in some space aliens, and 70 virgins to all the heroes who get snookered into flying on a death trap to die on Mars.

When on the real-looking amazon web page i clicked on 'add to wish list' and proceeded to enter my email and password. After I got done I was asked to enable popups, which amazon does not do. I also noticed that instead of the lock icon in the lower right corner of the screen there was a lock with a diagonal line across it. I'm just wondering how much damage was done in the minute or so it took me to change my amazon password.

This would have to be planned for in advance and by the use of simulations.
I'm not sure any action would have saved Columbia but if there was an opportunity to save the astronauts, even if the shuttle sank in the ocean, it should be available for future shuttle missions"
