@simontatham lovely Thanks! Looking at it, I wondered if it the computations and storage could be compressed in a kind of “hash life” way that exploits identical (but rotated and translated) units to avoid work?

@fesshole well, I understand quite a lot of crop plants are “cultivars” so different from the original wild plant you’d be hard pressed to know they were related. So it seems fairly plausible at least some house plants didn't really exist before houses either.

@johncarlosbaez @arsatiki this for me thinking about flow batteries for grid scale, and wondering if manufacturing availability and experience with automotive batteries means they won’t take off.

Perhaps a bit like the way hard disk packs got physically smaller and smaller, and if you want lots of storage, you buy lots of physically small disks, not a big one. ?

Perhaps not. Good physics reasons to avoid large spinning disks!

@johncarlosbaez don’t know anything about the donut battery? I’ve been looking out since they announced, but I’ve not heard a follow on yet. Could be nonsense?

@johncarlosbaez it’s 1,000km, right? Man. How annoying is that.

My current car has a 600km petrol range, and I need to take a 20m break after that. So.

Yay. Solid state batteries! Let’s gooooo!

@skinnylatte @tsvga my oldest son has started to learn Spanish with Anki, which he uses for university notes as well.

He finds its new learning algorithm uncannily good at predicting when you’re about to forget something.

He wants to learn Spanish enough to read online, so picking up vocab is his focus. But there’re lots of grammar decks available. He says you need to search about for good ones though.

@joby you must be here for the notifications then! Have we got notifications for you, kid! Want them?
