  • If you write !someCommunity@some.instance and aren’t on some.instance yourself, that works for everyone, regardless of whether their instance server knows about that community already or not.

    If you are on some.instance and write !someCommunity@some.instance, both lemmy and kbin are overzealous and it ends up only working for people on some.instance.

    In that case, you can use [link text for lemmy users](/c/someCommunity@some.instance) and [link for kbin users](/search?q=someCommunity@some.instance). The one for kbin users looks a bit different to guarantee the link works even if their instance doesn’t have anyone subscribed to [email protected] yet. Not sure if the lemmy link works in such a case.````````


  • IIRC it’s technically possible to attach an external harddrive to a Raspberry Pi if it has its own power supply.

    I seem to remember doing a botch where I took a USB hard disk drive that was supposed to get its power from the PC through the cable and rerouted the power over USB lines to a dedicated power brick.

    My memory says I carefully removed a section of mantle in the middle of the drive’s USB cable, cut the power carrying lines but leaving the data lines intact, cut one end of a different USB cable, connected the power lines of that with the cut power lines of the drive’s cable (only on the drive side, obviously), put the intact end of the second cable into a USB charge plug, and connected the drive and RPi as if the RPi were a regular PC.

    I’m pretty sure it worked.






  • Two reasons I can think of:

    • Information is more trustworthy if you can arrive at the same conclusion or at least understand how the other person arrived at it given the same information. If someone tells you that person X should be avoided, you could either blindly follow that advice or ask for a reason to decide whether you’d agree with the assessment.
    • Knowing the reasons behind something is also useful for extrapolating to new knowledge. A child who asks why they need to bathe will not just learn to wash themselves regularly but also about hygene in general, societal expectations about body odor and/or a possible disease vector.
