This sort of thing is disturbing. Amazon should know better.

SHA-1 collisions are getting closer. If you are still depending on the security of SHA-1 in your system, you should stop now. BTW, I keep wondering what git is going to do about it...

Dear Lazyweb;

Looking for a small/cheap ARM machine with two gig E ports. Any suggestions? (No, I don't want to add a USB ethernet onto something, so don't suggest that.)

Why risk rejection of your paper when you can assure it?

Very important work that you should contribute money to.

The notion here is very simple: the mitochondrial genome has been slowly migrating into the nucleus over the last 1.5 billion years, but there are (in humans) a few dozen genes left out of the original thousands that have not yet moved. In the mitochondrion, the DNA is in a much more hostile environment than the nucleus, significantly more subject to mutation and degradation, which is why there's the selective pressure for them to move to the nucleus where they're better protected.

A number of diseases of old age are strongly thought to be linked to mitochondrial mutations.

Aubrey de Grey & Co. propose to artificially engineer the move of the remaining mitochondrial genes to cell nucleus in model animals. This should presumably give them a boost in longevity, but how much of a boost is hard to know -- my suspicion is that in mice not much of a change will be seen until other aging effects that kill mice in only a couple of years are fixed.

Anyway, this is a worthwhile cause. If you want to see real progress made towards fixing the diseases of old age and extending human life, you should donate.

Using the Verified Software Toolchain, Appel's group at Princeton have formally verified the existing HMAC implementation in OpenSSL. You may say "so what, big deal, that's a tiny piece of software" -- but you would be wrong. This is the acorn from which great oak trees may grow. They're demonstrating that the techniques they are developing work. The size of the first project isn't the big news.

I'm suddenly getting added by loads and loads of obvious spam accounts on G+ -- started happening a day or so ago. Anyone know what the deal is?
