The Xerox Alto had a custom CPU that used microcode extensively - the CPU actually did most system management tasks like re-blitting the entire screen for every new frame and managing disk I/O, and only when it wasn't handling the

I definitely agree with you there. Often when I feel certain ways, I don't have reference points to mentally articulate how I'm feeling - if I even have the ability to consciously distinguish the feeling and highlight it. That shu

That's a fair point. I don't quite follow why speed needs to be sacrificed to get predictable performance though. And I don't know about writing a (whole new?!) Rust compiler (!) - if the current Rust compiler wouldn't

Huh, interesting. Apparently there are 35 rows in the table at http://www.felixcloutier.com/x86/MOV.html (according to Chrome and `$0.childElementCount`). I only discovered gcc.godbolt.org links to documentation via co

I agree. Writing in Rust might make the iteration/development process itself a little easier, I'll give it that. I also like the idea about creating a system that does its best to isolate components and create a trustworthy envi

QNX is also realtime. In order to provide realtime guarantees that cover small latencies, you need infrastructure that generates as few instructions as possible. (If you have lots of instructions you can hit targets of a hundreds of microse

You're referring to microkernel/nanokernel architectures. Linus famously shunned Andrew Tanenbaum's MINIX kernel design and argued in favor of a monolithic kernel, where buggy printer drivers live in the same memory space and

Computer science-y question. Initially this question was going to be "can we log executed instructions" but I rapidly realized that not even DDR5 could keep up with such a logging system - it would slow things down too much and li

DOH. I was going based on the thinking that the full email string would need to be known in order for it to be changed. My brain's a bit foggy right now so I can't properly think it through. Ouch, that makes things a bit harder...

Oh of course - interrupts. Right. Which is what [I now understand] preeemptible means; system interrupts can intercept normal execution and cause the kernel to go do something else for a minute. Thanks so much for explaining the read-write

Oh. That's unfortunate. Thanks very much for the headsup. I wouldn't mind learning more about this, perhaps via email (as an alternative to public discussion that might(?) start a flamewar).

I see what you mean. POSIX was basically a committee ratifying things that a bunch of systems people had come up with. So it gets to the point, it's reasonably concise, and there's little noise to wade through to do most things. J

It's sad you're being downvoted. I've found similar sentiment elsewhere, and I'm interested to learn more. stableperl ( http://blog.schmorp.de/2015-06-06-a-stable-perl.html ) is a fork of perl 5.22 with a

Yes, "stableperl" maintains a small number of backported bugfixes to Perl 5.22: http://blog.schmorp.de/2015-06-06-a-stable-perl.html The author cites a couple of issues as the motivation behind the release.
