  • /sbin is like /bin, but for system administrative type commands. /usr holds all the other software that isn’t critical to get the system up and running.

    A device file is a special file that’s like a pointer to a piece of actual hardware, like a serial port or a hard drive. /dev also has some non-hardware special files like /dev/zero. When you read from that one, you get an endless stream of zeros. Or /dev/null, that discards any data that’s written to it.









  • I think you’re massively overestimating what normal users are willing to do. Normal users aren’t going to install Linux because normal users don’t install operating systems. Other things normal users don’t do:

    • Install drivers
    • Configure hardware (including printers)
    • Run system recovery
    • Run OS upgrades (unless forced on them)

    When the upgrade from windows 7 to 10 resulted in broken systems/applications, some normal users paid someone to fix it, but most bought a new computer.

    In short, Linux is ready to replace Windows, but only in the cases where it’s sold preinstalled on supported hardware. Android, ChromeOS and Steamdecks are good examples of this.




  • One nice thing about learning (and teaching) python is that it’s a multiparadigm language. Students don’t have to learn about indenting until you cover flow control. Classes and OOP can come way, way later.

    I started with C++. Also multiparadigm, but the syntax and compiler errors were brutal, not to mention pointer arithmetic.

    I’m not sure I can think of a language that would be better suited to learning. GDScript seemed kind of nice, and you get to make games.
