  • Pretty vague question.

    One assumption that “mathy types” like to make is that the slope be negative-proportional to how far the value (not slope) is from the desired target value… and then you get an exponential decay (buzzword). But there are lots of other assumptions one could make… some of which lead to PID control (buzz; very mathy stuff).

    But these days you could use a neural net (buzz; so mathy they don’t usually pretend to understand what the NN “learns”) or fuzzy logic (buzz; which is ideally intuitive but has many surprisingly mathy assumptions) to make the behavior nonlinear and go to the desired result much faster… so really, there are many many possible answers. Maybe you can watch some ELI5 videos about these buzzwords and refine your question?


  • We have a political environment that lacks credible independent commentators (e.g. Walter Cronkite), so anyone presenting themselves as independent who calls bullshit on a politico is immediately labeled as biased.

    What mechanism do you think could overcome this and pull the mic plug to reduce the incentive to lie without immediately being vigorously attacked?


  • There are thousands of programs for Linux… but you should be warned that relatively few programs run natively on both Windows and Linux. In some cases there are ways to run “Windows programs” on Linux, but in general such successes are special cases. If you absolutely must have Windows you can run it in a virtual machine… but you will most likely be happiest with Linux if you aren’t chasing after such things.

    I use Windows for work because our IT department only supports that… but I use cygwin and wsl to get a smidgen of my familiar Linux tools that I use on my personal computers.




  • NPR sez Florida law would disallow him voting, but he wasn’t convicted in Florida, so they defer to the law in the state where he was convicted. New York allows felons to vote up until they are imprisoned, which doesn’t seem likely to happen before election day since he is appealing. Skin of teeth again.






  • Using sudo when it isn’t necessary, and the real cannon: sudo su… Adding sudo to your command lines indiscriminately causes files you create to be owned by root even though they are in your home directory, and then you end up using sudo to make changes to the files… and then the filesystem permissions cannot prevent you from successfully running an accidental “sudo rm -rf /” command.

    Seriously… sudo is not a “habit” to develop in order to avoid dealing with filesystem permissions problems.
