I love this kind of stuff, there is so much going on under the hood. If you do a calculation and ask a computer to print out the result, this involves actual work and algorithms to get what you expect. The computer can't just emit the number because it never uses "human" digits during calculations. @vitaut writes a library that does this conversion at lightning speed AND correctly.

@vitaut if this stuff fascinates you as well, I can recommend this post https://vitaut.net/posts/2025/smallest-dtoa/ on the modern "Schubfach" algorithm to convert floating point numbers to ASCII.

@vitaut I just spent some quality time figuring out how the ZX Spectrum did all this. "Mostly not that well". https://breatharian.eu/sw/float/index_en.html

@bert_hubert Interesting! I always thought they don’t have any FP support.

@vitaut Clive Sinclair had a history with physical calculators based on chips that really shouldn’t have room for floating point. The downside was that it wasn’t all that precise.

@bert_hubert @vitaut also it should be kept in mind that the ZX Spectrum was released before the IEEE-754 standard, and the standard itself was developed *because* the were a lot of incompatible and some honestly frankly horrid systems around, not just Sinclair's stuff.

@ni Hi. Co-author of ActivityPub here. Private distribution has always been a goal.

First, there's a document on possible integration models, which explains why this model was used.
https://swicg.github.io/activitypub-e2ee/integration-models.html
Second, bridgeability is a user story for the spec. I'd love to see encrypted messages cross bridges. MLS could help make that happen.

in the spirit of the holiday season: fedi uses activities like gift wrap. they unwrap them to get at the side effects inside, then discard them. activitypub is for publishing activities, so it's like gifting someone gift wrap. if they unwrap it, they get nothing. the gift wrap is the gift itself. the type of gift wrap you use says something all by itself. but a lot of people don't appreciate gift wrap. if you gifted someone gift wrap they might be confused and not understand it.

welp. the certbot program now no longer works on SPARC, because like many needlessly rewritten things that exist now, it now depends on something written in fucking rust. for fuck sake.
