Roughly 2/3 wind and 1/3 solar.

It would take around 1.1 million acres of solar panels to (clean) power the world. That's less than a quarter of the number of acres devoted globally to golf courses. You can see where this is going, right...?

For some reason, I expected some “resilience” perspective. Local first works when network breaks.

I kept these issues in mind when designing RDX.
It is a JSON superset, CRDT-centric, diffable and patchable.
Text and binary codings with round-trip guarantee, bit-precise spec (intended). Still raw, but works.

The era of manual software development is coming to a close quickly.
My view on software development has drastically changed. I believe in the future the role of engineers will be to build software factories, not the software itself.

I literally just found out (five minutes ago!) that they have finished shooting Neuromancer by @greatdismal.bsky.social and I can’t wait. This is the book that made me come out of the closet and tell people that I loved science fiction, which was unusual for a 20 yr old girl. It’s still unusual!
