Sometimes I wonder if the throat-clearing is an indispensable part of getting to the "good bits" that follow. Like, do those extra tokens give it more "room to think" even if they're basically meaningless in themselves?

It seems to me that the distinction becomes irrelevant as soon as you connect inputs and outputs to the real world. You wouldn't say that a 737 autopilot can never, ever fly a real jet and yet it behaves exactly the same whether it's up in the sky or hooked up to recorded/simulated signals on a test bench.

I'm sure it's fine you do it properly ([1] for example). The issue here was the utter lack of engineering, not the specific manufacturing technique (although those do seem to be highly correlated, due to low-end 3D printing having become very cheap and easy).

The extra fun thing about this is that eval has different semantics if it's assigned to a different name, in order to allow JavaScript implementations to apply extra optimizations to code that doesn't call a function literally named "eval": https://developer.mozilla.org/en-US/docs/Web/JavaScript/Refe...

Andy Wingo (of course!) has a good explanation of this: https://wingolog.org/archives/2012/01/12/javascript-eval-con...

What does the word "material" in "material support" mean if advocacy counts?

The "scraping helped slow it down" theory makes no sense to me. What do you think has a higher coefficient of friction - tire rubber on asphalt, metal on asphalt, or metal on metal?

"built to the highest Microsoft standards of security, privacy and performance" seems perhaps importantly different from "but to the highest standards".

Similar concept, though an important distinction: QFTF assumes that you have a phone you can scan QR codes with, but that isn't where you want the file to end up. Instead, it displays a QR code on both the sender and the receiver, and you scan both of the QR codes with your phone to start the transfer.

I've been working on a little utility to transfer files between two computers using QR codes: https://github.com/cibyr/qftf

It's kinda like Magic Wormhole without typing. It uses iroh for the p2p networking - on both ends, and also in the little web app that you use to scan the QR codes and start the transfer.

Imgur is particularly infuriating because it was initially touted as an alternative to the shitty image-sharing sites of the day (photobucket and the like) - one that would let you just link to an image without any bullshit. Now it's completely unusable.

New comment by cibyr in "There is no memory safety without thread safety"

cibyr — Fri, 25 Jul 2025 02:22:25 +0000

Zig's claims of memory safety are a bad joke. Sure, it's easier to avoid memory safety bugs in Zig than it is in C, but that's also true of C++ (which nobody claims is a memory safe language).

cibyr — Fri, 25 Jul 2025 02:17:37 +0000

Can a C program be memory safe as long as it doesn't have any relevant bugs? Yes, and you can even prove this about some C programs using tools like CBMC.

New comment by cibyr in "The borrowchecker is what I like the least about Rust"

cibyr — Sat, 19 Jul 2025 20:46:37 +0000

What's the alternative though? If you're fine with garbage collection, just use garbage collection. If you're _not_ fine with garbage collection (because you want deterministic performance, or you have resources that aren't just memory) then Rust's borrow checker seems like the best thing going.
