    This is confidently wrong.

    3^0 is also 1. 2738394728^0 is also 1.

    Edit: just saw that technically you’re correct - sure.

    IF base 2, Exponent reduction equals to halving - dividing by 2.

    For x^y reducing y by one is equal to dividing by x, then we have the proof it always works.















  • For remote backup, always keep your data in multiple ‘importance levels’. There’s replaceable, irreplaceable and very important.

    Replaceable is non-niche movies and all kinds of other things that are commonly available, data not ‘exclusive to you’. Irreplaceable is data that is (probably) only owned by you - photos, videos, source code, documents and so on. Very important are the few documents you really can’t afford to lose. Security keys, banking info and so on.

    I don’t bother backing up replaceable data - I keep one local and one off site backup for the irreplaceable data and very important data (1tb hetzner storage box is enough for me), and I keep a few encrypted physical usb sticks and sd cards strewn around at my parents and at work for the irreplaceable data that periodically get updated.



  • No, computing (as in general computing) will barely be affected. Computing uses semiconductors, which this (AFAIK) isn’t. Switching losses always occur unless you switch instantly, which is impossible. Most of the heat of cpus comes from there.

    Specialized things like quantum computing are a different story.

    What this superconductor could mean though: you could have a relatively thin cable from say, the Sahara to Europe, that can losslessly transfer energy. No losses whatsoever. So you can produce energy wherever energy is present, and use it where energy is required!
