  • And no, I have not tested it because I don’t know how I’m actually supposed to do that.

    depends on what you backup and how.

    if it’s just “dumb” files (videos, music pictures etc.), just retrieve them from your backups and check if you can open the files.

    complex stuff? probably try to rebuild the complex stuff from a backup and check if it works as expected and is in the state you expect it to be in. how to do that really depends on the complex stuff.

    i’d guess for most people it’s enough to make sure to backup dumb files and configurations, so they can rebuild their stuff rather than being able to restore a complex system in exactly the same state it was in before bad things happened.





  • Access control and offering a sound interface.

    You don’t need getters and setters if every attribute is public, but you might want to make sure attributes are accessed in a specific way or a change to an object has to trigger something, or the change has to wait until the object is done with something. Java just has tools to enforce a user of your objects to access its attributes through the methods you designed for that. It’s a safeguard against unintended side effects, to only open up inner workings of a class as littles as necessary.

    In a language without something like private attributes you’d have to account for far more ways someone might mutate the state of objects created by your code, it opens you up to far more possible mistakes.



  • I think i have roughly three categories for this.

    Needs: i need food/ my meds/ a train ticket to get to work

    Wants: stuff that i want for me beyond the needs, e.g. hobby stuff like a tripod if one is into photography or dinner in a nice restaurant from time to time

    Desires: stuff thats purely for pleasure. Like candy, or a new phone if the old one is still working or very expensive hobby related material, like that carbon tripod with all the bells and whistles, or material i allready own plenty of, like video games.

    Asking myself if something is still a want vs a desire stopped some impulse buys, but this desires very very tempting










  • Am a software developer, and in my experience we always find things that could be done different, spend hours tracking down the source of some fringe bug, or think of new features a product could benefit from, especially if we enjoy working on it.

    Things might be considered done, but i never was in a situation where one could not think of more things that could be done.



  • I guess some lessons need to be learned through pain.

    • Commiting regulary.
    • Following the branch rules.
    • writing tests.
    • writing tests, that test the desired not the current behaviour
    • refactoring your code.
    • not refactoring code, you don’t understand nor have tests for.
    • actually reading code before merging a pr.
    • not pulling in 23 unmantained libraries to solve a simple problem.
    • keeping your dependencies up to date.
    • that dirty hack will make your life harder.

    Yes, all those hurt. They sometimes still do, most of us are not machines that turn caffeine into code and we are never as clever as we think we are.
