1) Michael Jackson and Ryan Florence are demoing their Remix framework (React-based; the closest competitor is probably Next.js; but differs from it in that they are trying to reclaim traditional web techniques that many frontend devs — myself included — have forgotten. Anyway, Remix isn't free, so just watching it of an academic interest.)
2) RxJS Asia. Aired yesterday and — as an unexpected pleasant surprise — immediately made available on youtube. Considering that the last time they held this conference (also online) they didn't publish it for months, I'm flabbergasted. Hats off to them.
