just because it is digital doesn't mean it has to be a microcontroller though, right?? i see no reason this wouldnt just be a state machine or whatever out of plain old logic.

This is awesome! Just so you know, you are legally obligated to do Bad Apple when interest dies down.

Certainly not a "Rust UX _expert_", but I do find GPUI interesting. Some nice examples here of not-"just text/button widget programs": https://github.com/longbridge/gpui-component

I tested with 1.1.1.1 first, didn’t get anything, and gave up for the night. Maybe I should put a different provider as DNS backup? (any DNS gurus to say that that’s a bad idea?)

This is coming in the next release of Kicad: https://forum.kicad.info/t/post-v9-new-features-and-developm...

The rate of development since V6 is crazy fast IMO. Very much an OSS success story.

Thoughts on Zephyr? Especially wrt code size. I've heard all kinds of things regarding the requirement for it with Nordic chips

New comment by explodingwaffle in "Solving the ABA Problem in Rust with Tagged Pointers"

Who says you can’t make a library that does both? Rust makes it pretty easy to conditionally compile code based on architecture.

It could even be possible to make some sort of “ABA primitive” and use that for these sort of data structures. This could well exist: I’ve not looked. These sorts of things really aren’t that common in my experience.

On LR/SC: to any atomics experts listening, isn’t it technically “obstruction-free” (as per the Wikipedia definitions at least) rather than lock-free? (though in practice this makes basically no difference and still counts as lock-free in the C++ (and Rust) sense) Just something that stuck out last time I got sucked into this rabbit hole.

What would you consider the “RISC-V equivalent” of TrustZone? Last time I was curious I didn’t find anything.

(FWIW I agree with the other commenter that these ""security"" features are useless, and feel to me more like check-box compliance than anything else (Why does TrustZone work with function calls? What’s wrong with IPC! Also, what’s wrong with privileged mode?). Just seems like a bit of a waste of silicon really.)

New comment by explodingwaffle in "Inserting a 0 bit in the middle of a value"

explodingwaffle — Fri, 25 Oct 2024 10:55:46 +0000

that page + the book Hacker's Delight are a big part of the reason I am so convinced of this :)

If compilers/languages/standard libraries provided these bit permutations, and it was just something ~everyone had learned, it would be a lot easier to work with bits without needing to come up with the bitwise ops (or use that generator). In addition it would probably make better use of the hardware: sure, people like to pretend that we’re still programming C for PDP11, but modern hardware supports more operations than C has operators for (RISC-V B extension and co have the right idea <3)

Modern compilers are probably pretty good? but I doubt they are perfect at turning code like that in OP into the best instructions. It is probably a bit late for C/C++ though. maaaybe possible to get it into LLVM and Rust.

The more and more bit-hacks I see, the more convinced I am that they should be handled by a cleverer compiler. Some intrinsic(s) where you say “do x, y, to these bits” and it just figures out the optimum way of doing it for whatever platform you compile for.

New comment by explodingwaffle in "Apple Passwords’ generated strong password format"

explodingwaffle — Fri, 18 Oct 2024 14:12:52 +0000

At least in my iOS 18 Passwords app, the passwords are shown in a monospace font that (probably deliberately) differentiates all these (e.g. a slashed zero).

I wouldn’t call it a pet peeve but I understand where you’re coming from with this: but I think the main reason for it is electronic engineers, with little-to-no product design or even mechanical design/CAD background. IMO it’s a shame: it’s sort of like the open source hardware version of the “Blender before it got good UX” problem.

The cheap option is https://github.com/ataradov/usb-sniffer which is actually by the same guy as the OP :)

Open hardware so you could build your own for fairly cheap. I bought a clone (is it a clone if the creator never sold them? I'd have preferred to buy it from him...) off aliexpress for ~$50.

Great article. You would hope this feature was more readily exposed on USB-C laptops where it makes a bit more sense… oh well.
