Thinking about it the Apple II is a better example here, for one thing it's yet older (47 years). However I don't personally posses one nor have I ever used one so I concentrated on the C64. The author talks about doing timeless a

I find it odd the author spends lots of time talking about vintage typewriters but then fails to consider vintage computers which can give some real life examples of computers that are still usable almost 50 years on from their original rel

Does depend upon the project but I suspect this is far too low. Only thing you're likely to get in this price range is a small addition / tweak to an existing design. A very minimal design from scratch that uses existing off the s

Not OP but my partner lived in Copenhagen for two years. As with all of Scandinavia fluency in English is very common, practically universal in cities so you can happily live there without speaking a word of the local language. Also unlike

Is GPU rendering used today for VFX? From a quick google it seems that yes GPU based rendering is definitely an option, even if there's various reasons to still prefer CPU. So in your case was it really what you were aiming to do was p

Worth noting the story here has subtly that the headline cannot accurately capture. For one I wouldn't say this is about raising safety concerns or whistle-blowing, it's about how the employer views employees talking to the media.

Improved hardware based abstractions to provide stronger security and better ways to isolate software components just seems like a good idea. Yes you can certainly do plenty in software (in particular using language like Rust) but presumabl

Would be interesting to know what verification they've done on this core. Given it's included as a bonus feature presumably they haven't done full DV on it. The repository has a testbench for running binaries, which includes

by gchadwick 2y ago
At a guess it's because the author has been using Yosys for some formal verification work and maybe for doing some synthesis trials and it doesn't support system verilog natively. Though things are improving there: https:/&#

This looks awesome a really great step up from the RP2040. I'm a big fan of the original and I'm excited to see all the improvements and upgrades. I imagine with the new secure boot functionality they've got a huge new range

Are Google really pushing it a 'proper' security feature? You've quoted a line at the end of a blog that doesn't elaborate further. In the android documentation for instance it stats '[MTE] helps detect use-after-fr

Does this actually have any real world implications? If you're using MTE you already know there's a simple attack that succeeds with 1/16th probability (or maybe greater if you reserve some tags for special purposes or have s

Until James Hoffman ( https://www.youtube.com/@jameshoffmann/videos ) has done a video on it, it may as well not exist ;) Interesting idea, always nice to see new ways to brew coffee. I wonder how easy it is to replicate

This is already the setup, the foundation owns the trading company and it is the trading company going to IPO. From a quick scan it's not clear to me what share of ownership of RPi ltd the foundation would retain post IPO other than th

This is a good point though I'd argue that the spec isn't all that readable for some important things. For example the description of exception handling is sprinkled between the CSR definitions of the CSRs involved. There's n

Another issue I take with the RISC-V spec is it relies on a common understanding of technical terms without actually defining them precisely anywhere. To take one example it never defines what an interrupt is and more broadly never defines

ISAs are complex things so you can't say one is technically superior to the other. I would say you're right though in that RISCV enjoys the success it's seeing due to the open specification and licensing model. People general

This looks like a nice piece of work but worth noting that as it uses a stock RP2040 Pico board any hardening against physical attacks will be done purely in software so cloning the HSM entirely or extracting keys may not be too complex for
