OpenSCAD uses CGAL which allows for exact definitions for the rendered-out objects (as opposed to floating-point-inaccurate results; often observed as e.g. flickering coincident planes in OpenSCAD's non-CGAL OpenGL preview). What does

These are fair points. POSIX shell being fixed forever though also means it will /never/ get "fixed". Shell's silent-failure-by-default, implicit-by-default, principle-of-most-surprise semantics will always be there

Making your code public -- this works. I open-source all my code by default, and giving it to the world in good quality is a big motivator to do it well. It also builds you a nice portfolio which is useful outside of "work for yourself

It was a normal reboot via the Start menu. Quite certainly a cold reboot will wipe GPU RAM, but that's beside the point that software should make sure that unprivileged software from one OS should be able to read privileged contents fr

For many low-level languages, it's simply a matter of finding all malloc()s, checking the return value, and failing as appropriate. That can mean "not accepting this TCP request", "not loading this file", "not

My hunch regarding overcommit is that Linux should sort out this situation, making disabled-overcommit a first-class scenario. We (application developers) will follow and adjust our programs to correctly handle malloc() failure -- after all

This is good advice overall, in my experience. Most of the small/medium sized companies I've consulted for could have been easily served by a triple-redundancy Hetzner dedicated server setup for 200 EUR/month. Yet they they c

Note that using function-call based recursion is a programming mistake in most common programming languages, as they have a fixed sized stack. This includes many "functional" languages like Scala. Even Haskell had a default stack
