Me: "Ah, time to enjoy some simple CodeCAD, where if you take care, everything is reasonable"

CAD: "You have found today's Algorithm Surprise API! This object will henceforth have its coordinate system rotated by 180 degrees, but only 50% of the times you click render! Hopefully all your followup operations are rotationally symmetrical!"

@danderson build123d or something else?

i like build123d much better than cadquery, but yeah being a casual user it’s hard to get an intuition of what the cad kernel finds easy or not

On this day ten years ago, we lost our innocence as the former single page HTTP/1.1 specification (RFC2616) "exploded" into six separate new documents (RFC7230 and family). We could then no longer pretend HTTP was a simple protocol.

In June 2022, it was again updated:. "RFC 9110 and family". The spec is now split up into five main documents: semantics, caching and separate specs for each version: 1.1, 2, 3.

Those five documents hold 143,000 words combined. HTTP is not easy.

@bagder my favourite editorial error in RFC 2616 https://lists.w3.org/Archives/Public/ietf-http-wg/1999JulSep/0039.html “this media type MUST NOT be used unless the recipient can arse it"

wondering about waldo (n., telemanipulator) i find to my mild surprise

https://en.m.wiktionary.org/wiki/waldo

from the Robert A. Heinlein story Waldo, published in Astounding in 1940, derived from the name of the eponymous protagonist, Waldo F. Jones, who invented remote manipulators to overcome his own myasthenia gravis
