Um... you might want to look at my profile. In addition to working at MS and Apple for two decades (where I touched everything from firmware, ring-0, and ring-3), I was on the team that created SoftICE [0]: the first commercial ring-0 debugger for Windows. I also created the automated deadlock detector for BoundsChecker [1], which requires an in-depth understanding of operating system internals.
> computer systems whose backend implementations you are blissfully ignorant of
I am extremely confident in my "backend" knowledge (of course, an actual systems engineer would never refer to their work as "backend").
You wrote a "C++ framework" that runs in the "backend" of a "computer system"? Do I have that right? Please let me know what it is so that I can decompile it and see how it was implemented!
