vimes is perceptive when it comes to people. he understands that the upper class of ankh-morpork are hardly a meritocracy. he knows that *something* is up. but, i think, as a consummate policeman, it's hard for him to recognize legally-protected stationary bandits as the problem.

I recently read Born Against (blog.fogus.me/llm/born-aga...). I’m a member of the chess programming community, and while “characterized by gatekeeping and slow progress” is simply false of chess programming, I like the article. Even better is 87flowers’ comment: lobste.rs/s/3d3wbr/bor...

Imagining a social platform where if you use a fraught word like “knowledge” or “consciousness”, it pops up a list of interpretations of that word from the relevant SEP article and you have to select which one you mean. Then you get a short quiz on the common objections before you can post.

farewell and goodnight #SIGNALIS
Digital drawing of Elster and Ariane from the video game Signalis, depicted in the cryopod room aboard the Penrose-512. A warm light is emitting from the open cryopod, and Ariane is lying within it, smiling and cradling Elster's face as Elster covers her in a blanket. Another blanket is on the floor, amongst various music albums.

"The HTTP QUERY Method" by @jreschke www.rfc-editor.org/info/rfc10008
rfc-editor.org
RFC 10008: The HTTP QUERY Method | RFC Editor
This specification defines the QUERY method for HTTP. A QUERY requests that the request target process the enclosed content in a safe and idempotent manner and then respond with the result of that processing. This is similar to POST requests, but QUERY requests can be automatically repeated or restarted without concern for partial state changes.

“no silver bullet” is one of those ideas which has poisoned the discourse around programming. You can dismiss any process improvement by just saying there’s no silver bullet. I don’t think I’ve ever read a comment which reminds us of this fact that was worth reading.
