astronomy is so funny because it's this fairly niche interest for a small community of nerds and also it's 99.9999% of everything that exists

have revised this take: i think i was underrating how much intuition building happens as part of the process of writing science code. Claude can get to many subproblem answers faster than I can but I end up feeling hollow - missing a sense of satisfaction I didn't know I had till it was gone

as someone who may not be a researcher if not for prof layton this is so sad but also, not clear to me if this is more like "we should let ai write the layton puzzles" or "we should write the game in cursor instead of vscode" - even when specified to genai we seem to have terminology issues

the bay bridge has a bike lane but only halfway across, so if you wanted to bike from the East Bay to SF for the 4th of July fireworks you'd have to bike all the way north to Point Richmond, across to Marin, and down across the Golden Gate Bridge. But that'd be ridiculous right
Me standing on the bay bridge at the halfway point. I'm wearing a fluorescent green jacket and a bike helmet. I'm frowning and have my thumb down as if to say "it's unbelievable that you can't bike any further here"The bike path on the Golden Gate Bridge, with another cyclist ahead and with a couple of cars crossing the bridge to my left
Me smiling with a thumbs up on the SF side of the bay bridgeA Strava map with the route I described in the main post. The ride is entitled "spite". I had an elevation gain of 468m, time of 5h 14m, and a distance of 83.03km.

Also experimented in parallel w this based on the same blog post and reached the same conclusion - I liked not having to do my own env setup and the odd bit of refactoring but you lose more time to it having nonsense strategies/not trying basic validation than you gain

Interesting article from @adiastra.bsky.social I think my hottest take here is that we kind of already have this and it's called "getting an undergrad to do the analysis" and it's probably responsible for a bunch of errors we haven't caught yet aditya-sengupta.github.io/vibescience/
