WITHOUT ROWID is a very useful tool to have in the bag for sqlite. didn't know this was a thing.
I've got a very large many-many map table with a composite PK of two integers, like left_id, right_id.
turns out by default sqlite adds a rowid meta-column to tables. when the PK is a single integer it's a direct alias (no additional storage) but in other cases, like my table, it ends up as a separate stored value. for small row sizes this is rather space inefficient. it can also be slower to query

Curiously enough, the only thing that went through the mind of the bowl of petunias as it fell was Oh no, not again. Many people have speculated that if we knew exactly why the bowl of petunias had thought that we would know a lot more about the nature of the Universe than we do now.
personally i'm ok with AI techniques being less well known but there's a deeper thing going on here which is far more important IMO, because it's also partially why LLMs have taken over

RE: https://kolektiva.social/@beka_valentine/116845902133405690
An excellent thread here. So much of what I see people pointing to as LLM's benefits for coding relates to long-standing problems in software engineering that the field just hasn't addressed. And LLMs don't solve these problems, at best the just paper them over and make dealing with them less tedious -- while reinforcing the problematic dynamics.
So yes it's great that people with no programming skills can create software to solve their prolems. But if we had collectively spent a chunk of the literally billions of dollars that are going to "AI" building on the early approaches to this from 25+ years ago (Hyperscript, Logo) that don't have the same downsides, we'd be in a much better place today.
For decades, the KKK marched and protested wearing masks, and Dem lawmakers said, "It's free speech! We have to let them talk!"
Then for a few summers, some Black kids said, "We need a ceasefire in Palestine." And Dem lawmakers passed laws against masked protest.๐คก
Now those Dems are quiet again.๐คท๐ฟโโ๏ธ
Blog post: Inspired by the video I just boosted - some honest thoughts on my AI remorse from my experiments earlier in the year.
It was bad, and I have SERIOUS regrets.
Agentic AI has "guardrails" (e.g. you have to explicitly say "don't delete all the files on my computer" if you don't want it to delete all your files).
One of these guardrails is asking users to confirm whether to do things. Claude Code apparently has now decided that if you take over sixty seconds to answer a question, it'll just go ahead.
Turns out guardrails get in the way of consuming tokens, and you must consume tokens in order for the business model to work.
