explodingwaffle··on How did AMD Ryzen get 50% faster in two years?
coded entirely or partially in assembly, i presume?
explodingwaffle··on Authorize, don't authenticate
I really like this concept (though the post is terribly named as others have said). "Databases that are easy to make as documents" is so obvious that you wonder why it isn't more of a thing. Add in "untitled" databases that live in a session/browser so you can "try before you buy", maybe the option for single file databases with no intermediary/service (so you have a Databases folder that is as messy as your Downloads folder... but is that really so bad? better than a password manager full of garbage services IMO), and you basically get EASY seperation between application and data, which is Good for a lot of reasons (lock-in, ownership etc)
explodingwaffle··on 98% isn't much
man, HN is awesome
explodingwaffle··on TCXO Failure Analysis
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.
explodingwaffle··on Usenet personality
this is great, thanks for pointing to it! been looking for this ideal sort of RSS reader
explodingwaffle··on Show HN: I spent 6 years building a ridiculous wooden pixel display
This is awesome! Just so you know, you are legally obligated to do Bad Apple when interest dies down.
explodingwaffle··on I tried Servo
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
explodingwaffle··on Tell HN: 1.1.1.1 Appears to Be Down
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?)
explodingwaffle··on Thunderscope update: My take: Why open source is better
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.

explodingwaffle··on Just barely fitting a full Wi-Fi stack on the nRF9151
Thoughts on Zephyr? Especially wrt code size. I've heard all kinds of things regarding the requirement for it with Nordic chips
explodingwaffle··on 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.

explodingwaffle··on T1: A RISC-V Vector processor implementation
TIL this github "list" feature. neat
explodingwaffle··on VPR: Nordic's First RISC-V Processor
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.)

explodingwaffle··on Inserting a 0 bit in the middle of a value
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.

explodingwaffle··on Inserting a 0 bit in the middle of a value
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.
explodingwaffle··on Apple Passwords’ generated strong password format
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).
explodingwaffle··on MikroPhone: A privacy enhanced, simple and featured RISC-V mobile phone
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.
explodingwaffle··on USB Sniffer Lite for RP2040
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.

explodingwaffle··on Rust for Embedded Systems: Current state, challenges and open problems
You mean, like this? https://probe.rs/docs/tools/debugger/
explodingwaffle··on I turned my ThinkPad into a programmable USB device
Great article. You would hope this feature was more readily exposed on USB-C laptops where it makes a bit more sense… oh well.
explodingwaffle··on Bard is now Gemini, and we’re rolling out a mobile app and Gemini Advanced
I thought it was just supposed to be a pun on “gen’ AI”
explodingwaffle··on Macs can now inform Apple if any liquids have been detected in the USB-C ports
Yes: because Apple actually got this added to the spec: https://www.usb.org/document-library/usb-type-cr-cable-and-c... which is the real story IMO (I am impressed no one bothered looking at the Type-C spec update after the Type-C iPhone finally came out)

This actually replaced the analog audio mode (good riddance- whoever thought adding analog audio into a port that also does digital audio was a good idea?)

explodingwaffle··on Dieselgate, but for trains – some heavyweight hardware hacking
Did the manufacturer really think they would get away with such blatant shenanigans? I imagine the lawsuit for this is going to be open and shut.
explodingwaffle··on Rust std fs slower than Python? No, it's hardware
Anyone else feeling the frequency illusion with rep movsb?

explodingwaffle··on A four year plan for async Rust
Tangential to some comments here: Why does the standard library not have block_on?
explodingwaffle··on DigiSpark (ATTiny85) – Arduino, C, Rust, build systems
I'm curious, so I'll bite: what do you find hard to setup about embedded Rust? Personally haven't found it too bad (this is STM32/Cortex-M though, which is sort of a happy path)
explodingwaffle··on Raspberry Pi 5
It’s worth noting that this is _allowed_ by the USB-PD spec, but you’re right that 5V @ 5A is not common because it is not required. At least it’s better than the Pi 4 was at launch? :D
explodingwaffle··on The Federal Helium reserve is for sale
"To protect your organization from excessive usage and Denial of Service attacks, we limit the number of allowed content delivery views within a twenty-four hour period. Try viewing the content again later."

C'mon guys, I was reading that 240 page government contract!

explodingwaffle··on Exway doesn't care about USB-C conformity
As someone who has read the PD spec and agrees with your assessment- I’m curious what that chip is?
explodingwaffle··on Stop trying to make social networks succeed
> “feeds”

People keep using this word when talking about what’s been happening with the internet recently- but they don’t realise how close it is to the actual answer. RSS has been around forever and it’s exactly what is needed. A feed reader can check thousands of blogs, comment sections, youtube channels, newsletters (imagine never being asked for your email randomly ever again), podcasts, whatever.

The real issue is (and should be) discovery. Make feeds more obvious (say, it was integrated into modern browsers. Some sort of first class “feed detected” icon) and then all you need is search, which has also been solved forever (hopefully it stays that way…).
