The real reason behind isolated systemd services is to confine the damage if a world-accessible daemon gets breached. If your threat model is you can't trust the programs running on your computer, then maybe you should switch to a diff

So? Local programs also have access to the filesystem, which includes the synced data, config files and procfs. What exactly is your threat model?

What fails? Some commercial C/C++ compiler producers invest into a debugger typically because some of their customers use it on a platform without a good built-in debugger. Yes, some systems had debuggers. The point is, some didn'

What you say has nothing to do with languages and it precedes 80s; Watcom, VC++ etc. comes with a debugger because the proprietary system they run on doesn't have one. GNU/Linux always had gdb. So if you want me to spell it out, h

And I find this expectation rather bizarre. Since when compiled programming languages ship a debugger? You can use a world class debugger, known as gdb, with Go, and yes, they do provide extensions for gdb to make it understand high-level G

That kind of empty loops are actually used for delays, waiting on interrupts to kick in etc. in embedded systems, where you typically fight against the compiler using volatile keyword. Example from https://www.coranac.com/to

Microfacets is just one example (which is what PBR approximations today ubiquitously use BTW). The very idea of a B*DF function for light is a rough approximation, and can never capture a variety of quantum effects. You can simply never r

That's just a plumbing problem which can be solved by lowering temperature or using a different material with lower resistivity. Yes, it'll probably cost more, but it's a problem that can readily be solved. But if your switch

Similar is true for HDD BTW. Consumer grade HDDs are stuck at 8TB since 2015, and their prices keep hovering at around $200. But it's not due to lack of technical progress. There are 10TB, 12TB, 14TB drives out there, but there is a hu

Packaging needs to be improved, especially given that it requires their fork of llvm and clang. deb/rpm files or at least a PKGBUILD would help make it a lot more accessible.
