  • I'd agree with the choice of Debian (or a derivation as LMDE, *buntu, Linux Mint, ...), but would suggest KDE. Anyway, I think a beginner should try the distro of their choice on a live medium first to get in touch with the look and feel of the desktop environment.

  • Yes, it was a course on finite deformation material models. And no, you do really, really not want to declare each and every variable in your material subroutine globally for the whole finite element program.

  • Yes. He really thought it was efficient and would avoid errors if literally all variables were defined in a single Matlab function he called at the beginning of the script. We students all thought: "Man, are you serious?" As we didn't want to debug such a mess, in our code, we ignored what he was doing and kept using local variables.

  • I've once had a course involving programming and the lecturer rewrote the code, which we were usually using at our institute, making ALL variables global. - Yes, also each and every loop counter and iterator. 🤪

  • No, since the contact face has constant size which is mostly dependent on the air pressure in the tire, for fat tires, the contact face is 'shorter' but 'wider' compared to a slim tire. Thus, as less rubber needs to be deformed in rolling direction creating an angular momentum, they have lower rolling resistance. However, at elevated speeds of 20 km/h (~15 mph) and above, the air resistance, where slim tires perform better, becomes more important. Thus, racing bikes have very slim tires under very high pressures (also inertia plays an important role here).

  • According to Wikipedia, wireless USB should be secure too: "The goal of the specification was to preserve the functional model of USB, based on intelligent hosts and behaviorally simple devices, while allowing it to operate in a wireless environment and keeping security on a par with the levels offered by traditional wired systems."
