@ Re secure device discussion
Tough not coming from hardware design, I'd like to join such a SIG on secure device building. Probably more for learning than for contribution, I hope that's ok.

Your brain is not tamper-proof. Alzheimer's desease is an example for it, losing the brain capabilities without noticing. In case the tamper-proof works (i.e. you notice your decay), it gets just the more horrifying.

QWERTY cards reduce the set of possible output characters notably. In case I get someone's QWERTY card, I can tell which characters are very probably not in his password.
Looking at the card carefully, having it rules out the majority of chars possible in a password. Has Gvmt started handing them out yet?
Nevertheless, the conceptual idea is worth working on the implementation flaws.
@ Thoth, Re security model
I believe that many aspects of security and usablilty contradict strongly as usability wants the user to understand as little as possible about implementation details yet many other aspects need the user to be aware of them. As a result, we have many more-or-less working secure systems that can only be used when understood and snakeoil that claims to be secure albeit being just usable. For a quick example, try to introduce a political journalist to PGP/GPG without spending time on explaining the asymetric crypto stuff...
@ Winter, Re Paris attacks
It's sad. Since "more security measures" is just another word for "less individual freedom", the terrorists win. No politician with even a slight feel for populism (that is, all/most politicians) will say "that's a threat we have to learn to live with". European politicians will react and I'm pessimistic about it.
On the other hand it's impressive to see the popular reaction, especially among the European media workers.
However, one may ask the usual: False flag op, which topics have been hidden in the media, any paralell construction, etc. Less than fifteen people killed, whole Europe in roar, that's efficiecy.
The Charlie Hebdo assassins and their hostages died inside a printing plant, from what I've heard. If true, that's bitter irony.
