I recently started using Linux again, and decided to try and fix some of its more ancient and silly UX paper cuts. This is my first success! My attempt to fix the annoying and unnecessary 2 second delay when you mistype your password is goi

If you get lost in the SEW, LMUL, VLMAX, etc. stuff I made a brief explanation here: https://blog.timhutt.co.uk/riscv-vector/ It has a visualisation of the element selection stuff at the end.

It's going to be optional - the hooks will always fix the code if they can, but then you can supply a `--no-fix` flag (or config) if you want to tell it to not actually apply those changes to the real filesystem. It doesn't need L

It is better because of WASI. That's what provides sandboxing.

You could say the same about Dutch to be fair. 90-95% speak English - I bet that's way higher than in Poland.

Yeah it messed up a bit for me too when I didn't enunciate well. If I speak clearly it seems to work very well even with background noise. Remember Dragon Naturally Speaking? Imagine having this back then!

I have also been working on an alternative written in Rust, but in my version the hooks are WASI programs. They run on a virtual filesystem backed by the Git repo. That means a) there are no security issues (they have no network access, and

TOTP is really annoying IMO but at least you control it so you can make it one-factor again if it's foisted on you. I made a Chrome extension to do that: https://chromewebstore.google.com/detail/lazyotp/eoihmk

The absolute prefix requirements (similar to Nix, and I guess for the same reason) mean this probably can't be used where it would be most useful - on machines that you don't control. I wonder if anyone will ever make something li

I don't think you would be flagged. Rust definitely has flaws: * Compile time is only ok. On par with C++. * Async has a surprisingly number of footguns and ergonomic issues. * There's no good solution to self-borrowing or partial

Those architectures are all much older than RISC-V from a time when it wasn't quite so blindingly obvious that Little Endian had won the debate.

Python still doesn't do very well on backwards compatibility & bitrot, even after 3. They're constantly deprecating and removing things. https://docs.python.org/3.12/deprecations/index.html This obvi

I'm pretty sure Rust is going to outlast x86! C definitely will.

I think assembly is probably a pretty bad choice for a RISC-V emulator. It's not portable, a nightmare to maintain, and not even as fast as binary translation. What kind of performance do you get? I guess it would be a great way to lea

I think that change is talking about the minimum timeout for the first 5 nested calls to `setTimeout(0)`. Previously the first 5 would take 1ms, and then the rest would take 4ms. After that change the first 5 take 0ms and the rest take 4ms.

I have a lot of experience with pairwise testing so I can explain this. The reason there isn't an "equal" option is because it's impossible to calibrate. How close do the two options have to be before the average person

Yeah you can describe basically any ISA including SIMD. The RISC-V model doesn't support packed SIMD (the P extension) but it does support Vector.

It's still kind of experimental. Also the purpose is more for formal verification against a real design. The RISC-V model doesn't have any microarchitectural features you'd need for a real chip - not even pipelining - so it w

I've used this a lot via the RISC-V Sail model: https://github.com/riscv/sail-riscv It's a really nice language - especially the lightweight dependent types. Basically it has dependent types for integers and

Yeah I also don't understand how this is unexpected. You gave Claude the ability to run arbitrary commands. It did that. It might unexpectedly run dangerous commands even if you don't connect it to malicious emails.

That's a maximum . It's extremely unlikely that they would actually get jail time. Maybe a suspended sentence at worst.
