NotebookLM is such a good idea and it would be so useful if anything other than a Gemini model was running it. Nothing has convinced me more than this that Gemini models are incapable of doing anything other than directly parroting the exact material fed into it.

Random UI shit that bothers no one except me: For some reason only ~half of the new Apple Music posters have UI color matched to the artist logo. Maybe this is for legibility but they do it with dark colors sometimes…

oh shit the new codex cli is amazing full screen tui and can manage multiple agents at once it's finally back on par with the desktop app (plus they even added voice mode with gpt-live which I'm never gonna use but cool that it works in the tui)

Sometimes I’m lying in bed and I think of something and ask Siri to remind me of it. Usually I know what they refer to or have some vague idea of what I meant when I look at them later. But what the fuck could this possibly mean

Don’t think I can offer anything super useful. Swift was the first language I learned and I was very young so the specific features of the language were unclear to me. I used swift playgrounds which is (afaik) specifically for kids who haven’t coded before so I assume it’s not the most optimal path

Bad day to be a Lando Norris fan. Really weird strategy to pit right after the yellow flag ended. DOTD gotta be either him or Verstappen.

everything app doesn't even mean anything anymore everyone just uses it when they're adding like two more features to their app.

this deeply nerdsniped me because the previous company I worked at, LSD, was exactly this kind of SQL but for the web e.g. FROM news.ycombinator.com SELECT a AS col1 , span.sitestr AS col2 GROUP BY span. titleline; I might try to rebuild it this weekend but for querying records from PDSes.

yeah I wouldn't recommend building with puz for a new app (it's a very frustrating and inflexible proprietary format) but it's probably smart to support importing puz and maybe converting them? I haven't gone super deep but I know conversion tools exist.

Roscoe Rubin-Rottenberg @knotbin.com · 26/08/2026
I don’t know of any that exist but the .ipuz format is just JSON so that seems pretty easy to make into a lexicon.

I'm so glad you enjoyed it! How was the difficulty? I didn't post it before because I didn't get anyone's feedback who fully finished it so I didn't know if it was way too hard or way too easy.
