The dirt (ground) of japan and singapore is not magic and does not confer safety, if that is what you are asking. It is a factor of something else > "my family is prohibited" christ almighty Yes, I take their safety seriously.

in my opinion, yes. Given that it was a clean-sheet design with no legacy to support, and that it was done so recently as to have easily had the benefit of all the lessons of x86, mips, arm, sparc, powerpc, etc, yes, it left a lot of obvi

Oscar Toledo, you are simply insane (in a good day). I bow my head in respect at the completely pointless and insanely impressive result.

This is how you get vigilante justice. It is only held back by people believing that the state will treat them fairly in a court. Once the majority no longer believe that, you get chaos. I am entirely sure we do not want that. The correct a

I am sorry if my point was not clear enough. I don’t advise anybody to stay away from it. In many ways it is good enough. I just think that if you were designing something from scratch, you could actually learn from past lessons, rather tha

At least for me, I agree with both of the things you said. RISCV is a significant improvement on a lot of of the status quo in situations where it is currently getting design wins. But it also could’ve been a lot better in simple ways that

With enough effort, you can make a brick fly. X86 proves this. But if you are designing a new flying device, despite the fact that you could make a brick fly, you probably don’t want to design a brick. Why make it harder on yourself? Riscv

There is very cool history as to why. In armv5 the BL was two separate instructions . You could take an interrupt in between. And it was documented what each did. Veeery cool. Then they wanted more range. And now that they redefined the tw

If those people build cores like linux kernel is built design-wise, i will PAY to watch the spectacle. You do realize that Linux got basic SMP support 3 years after NT, and it was shaky for a while after? It still does not have reliable sle

Given the amount of learning that could have been done before RISC-V and wasn’t, I wouldn’t have such high hopes.

Very often. Yes. Or software that will run on any similar arch by auto detecting the environment.
