It’s 2am. Do you know where your sleep is?

I immediately thought about this, which I posted awhile back. Maybe part of why we seem to be getting dumber as a society is that we’re all sleep-deprived idiots. Certainly should impact reaction times, anyway.

HMMMM.

(This post would be more witty and insightful but I’m pretty tired right now.)

The Scientifically Best Times To Drink Coffee During The Day

Despite the big words, the original blog post is a little simplistic. It doesn’t take into account absorption rate, half-life, or conditioned tolerance. All of which I make a half-assed effort at trying to do. Also, I suspect my circadian rhythm doesn’t match this dude’s description of the “average” circadian rhythm. But, enough about me. It is definitely an interesting way to think about caffeine consumption.

the hackability of pacemakers and other medical devices

And, I kinda hate to even reference him, but this is back in the news because Dick Cheney recently admitted that he had apparently been worried about it:

A bit earlier this year, the issue made the news because Barnaby Jack passed away, a week before he was supposed to present at the Black Hat Conference regarding hacking medical devices:

Anyway, all that to say, this is one more thing that is going up on my blog because I find it interesting (srsly? That’s *that* easy to do? It’s not just scifi? That seems… kinda bad.), but that, by my posting it, probably makes me sound like I’m walking around in a tinfoil hat.

Gaia delayed

Pretty much what I get from reading all this is:

1. Gaia is hopefully going to be giving us oodles of cool information about space and the stuff that’s out there in it.
2. Brown Dwarves are a real thing, and also, despite their name, are entirely unrelated to Tolkien or D&D.
3. Einstein’s General Theory of Relativity continues to be poked and prodded by science. Meanwhile, Hofstadter’s law continues to appear unavoidable.
