‘Figgins’ a.k.a. ‘Sam and Figgins’ (self-portrait in studio with model), Sam Haskins, 1961.(A better ‘behind the scenes’ self-portrait i.m.o. than Helmut Newton’s ‘Self Portrait with Wife and Models’, which is itself also a favourite of mine.)

I currently have one of those bugs that I tell people doesn’t happen in Scheme because of monomorphism … unfortunately, some things aren’t monomorphic enough :-((And yes, static typing would probably have caught the cause – as-yet unidentified – before it ever happened at run time. Sigh)

@kakafarm The bug? I was constructing a record based on a list. There’s a special case for a singleton list that should construct a different record type A with the item from that list; lists of more than one item go into record type B. But in the special case, I forgot to actually pull the item out from the list, and instead constructed record type A with its field being the list itself, not the item from the list. So other procedures saw a list of α when they expected just an α.

@kakafarm Eventually this would have been caught by my test coverage checking with Meze, but I hadn’t run that yet, and my test data just happened not to tickle that special case yet.More monomorphism (type checks on record field values) would have helped because, once the special case code ran, the error would have been reported at its origin, not when some other procedure found data of a type it didn’t like.A static type checker would have immediately noticed the issue before even then.

Gruber has been full of shit lately, but does manage to capture something I’m also uncomfortable with about the hero-worship of AaronSw

@vmstan @cwebber @lgsp Was there ever any year where web design was better than it was in 1999? I mean just look at this stuff. Unbeaten tbh https://www.webdesignmuseum.org/all-websites/year-1999

When was the web more user-hostile: In the late 1990s (pop-up ads, website splash screens, auto-play MIDI, etc.), or now (gestures wildly)?

Scheme WG2 is now going to hold regular synchronous meetings, which I hope will be the main venue for actual decision-making going forward.Everyone is welcome.https://scheme-reports.simplelists.com/scheme-reports/msg/32450016/
