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.)

MSRP of $239 makes the x15 not very worthwhile.

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.

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...

The candidate replacements are:

SHA2-256 (weathered recent advances much better than initially expected and holding up quite well)

SHA2-512 (wider than SHA2-256, but faster on some CPUs because it processes more data per iteration)  If space constrained use SHA2-256, if not consider SHA2-512 or its truncation SHA2-384.

SHAKE256 (128-bit security-level for both collision and preimage resistance, faster than SHA3-256, new "sponge" design addresses some Merkle–Damgård limitations)

Blake2 (faster than SHA3 and a non-NIST algorithm if that appeals to you).

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

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.

cool. wish some of the early verified compiler work for scheme (wand et al) could have been put to this kind of use instead. we would have been ahead by two decades.

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?

French art film director Chris Marker made what seems to be the first and nearly most highbrow cat video of all time in 1994.
