    This one, if by unix he also means modern linux systems. Nowadays you can simply use tar xf my-file.tar.whatever and it should work on most linux systems (it worked on every modern linux system I’ve tried and every compressed tar file I’ve tried). I don’t think it is hard to remember the xf part.

    Generally such problems include sentences such as “Assume their velocity to be constant” and “They are traveling in a straight line” to avoid ambiguity that could confuse the students into thinking the problem is a lot more complicated than it actually is supposed to be. (and to prevent students from claiming afterwards that there could be more than one solution or that there is no knowable solution and that therefore the problem is invalid and should therefore not count towards the test’s grade)




  • What I find interesting is that my bank has kind of the opposite stance. It allows you to do a lot more things if you login via their website and I think they overall trust your actions more if you do it over the browser, but you are required to pass a lot more security checks, while on the app a PIN is enough, but it also doesn’t allow you to do as much.








  • I never got the pipe analogy. Since liquid water can’t be compressed, wouldn’t the amperes be directly proportional to the volts and to the size of the pipe, assuming there are no air bubbles? Also, supposedly resistance only reduces current, but when I think of hair in a pipe, the pressure after the obstruction would also be lower (because pressure is directly proportional to the amount of water that flows)
