  • People say that like the replacement parts are just a mystical thing that spawns out of thin air once they need them.
    Most parts that break are injection molded plastic. Injection molding is what differentiates manufacturing and home made garbage. Something home made will never look and function as good as something injection molded by a manufacturer. And the reason for that is cost. To say injection molding is expensive is an understatement. The machines, the tools, the expertise and the material is something that a private individual could never afford and has barely any profit margin for manufacturers. On top of that there’s storage and distribution.
    So if a manufacturer has to produce extra pieces of each part that might break, store and keep track of them for 10+ years for models that are no longer produced, then the customer better be ready to cover those costs with their initial purchase or have the replacement part be ridiculously priced.
    We accuse companies to want their cake and eat it too, but the we do the same thing. We want products to be cheap but also reliable or look good but be repairable. We can’t have all.\

    This is only partially true. Yes we do engineer things to fail at a certain point, but that’s only because back in the day we naively assumed that we could engineer things not to fail at all.
    Yes a stator of an electric engine will probably not fail for 100 years, but the seals will - yes the statically stressed metal part will hold until it crumbles to rust, but the dynamically stressed plastic part won’t - yes the silicon in an IC-Chip is protected from corrosion, but the connector pins aren’t.
    The point I’m trying to make is that there’s always a part that will fail before another, there’s no way to economicaly engineer around that, today we simply have the data to statistically define a failure point.
    A fridge usually has a 10 year warranty. This isn’t even the end of life point. After 10 years it’s most likely that 80-90% of devices will still work. This means that if your device survived 10 years it will most likely work for another 5-10 years.













  • This is the “appdata” folder, this is where all the application’s data goes.

    So whats the “Programs” folder then?

    This is also where the application’s data and files go.

    But I thought thats the “Programs x86” folder.

    This is also where the application’s data and files go.

    Ok whats “Program Files” then?

    This is also where the application’s data and files go.

    So my config file is in either one if those 4?

    No thats in the “Documents” folder, obviously.

    Windows program data file structure has always been the wild west.



  • A lot of people talk about straightness and flatness as mathematical concepts. But I think OP means it in a technical sense, as in flat like your phone screen or straight as the edges of the screen but in nature. In this sense, flatness or straightness is defined as a finite number of measured points on a surface of which the coordinates all lie between 2 mathematicaly flat/straight parallel tolerance planes/lines. By that definition, depending on what a person would consider flat, say 0.002 mm between the planes/lines, there are definetly naturally occurring crystals that would pass that test.
