It seems like it's deindexing everything but the biggest sites, so it fails at basic tasks like "find a blog post by a specific person on a particular subject, which I know exists"

Comic drawn in MS paint, based on https://www.homestuck.com/sweetbroandhellajeff/001

The first panel shows a man saying "I warned you about kathryn Bro!!!! I told you dog!"

The second panel shows a man falling down the stairs.  He has Crespo's avatar, and is surrounded by birds (@kathryntewson.bsky.social 's avatar)

The third panel is the second panel repeated a bunch of times, very pixelated.

The final panel is the first guy again, saying "I told you man.  I TOLD you about Kathryn"

Screenshot of a Google AI overview reading

WGSL does not explicitly feature a dedicated tail_call keyword, but the compiler may optimize tail-recursive calls into loops to avoid stack overflow, particularly for simple function tail calls. While not guaranteed by the specๅฐพ call optimization (TCO) allows the return of one function call directly from another, saving space

(yes, that is a Chinese character in the middle of the response)

screenshot of a large switch statement matching on an opcode.  Each opcode has an implementation that reads and writes to a reg array, but they're all often different shapes (different numbers of arguments, etc).

Screenshot of a similar switch / case table, but every branch has exactly the same form of "tmp = op_NAME(lhs, rhs, stack)"

A picture of a shot from "The Last Of Us" (TV show) showing a scenic forest full of pines and a river.  The caption on the screen is "10 miles west of Boston".  This is funny because in reality, 10 miles west of Boston is... still basically Boston.

ssh is an obscure but widely-deployed command. It stands for Secure Snake Home and was made in the 90s to securely play snake online

I made a massively multiplayer backend for it with support for thousands of concurrent snake players

ssh snakes.run to join!

Of course, this would be inefficient to do for just me โ€“ you'd want to have larger caches that could be used by multiple people, to amortize the cost of restocking them.

That would be a lot of effort to do for just myself โ€“ I think you'd want to serve more than a single person, to amortize the cost of restocking (which then requires a greater-than-Tupperware sized physical footprint).
