  • Sounds like SEE (single event effect) if it’s something fixable by software.

    TID (total ionizing dose) is another flavor of radiation effect on components, but that’s a total lifetime effect where it slowly degrades. Using rad hard parts or adding extra shielding is the main fix.

    SEEs are transient effects from high energy charged particles that can cause bit flips and latch ups in circuitry depending on where the particle hits and deposits it’s charge in the circuitry. Extra shielding can help prevent these as well, but they can also be mitigated in software, sometimes the fix is just error detection, or power cycling a specific section of circuitry to clear a latchup


















  • So. Funny story. Back when I was incredibly new to Linux, I was trying to move everything from my downloads folder to somewhere else. So I navigated into the downloads directory on the command line and sent something like

    “sudo mv /* ~/misc”

    when I meant to type

    “sudo mv ./* ~/misc”

    Yea… That was a fun learning experience and hilarious way to utterly fuck everything on that machine. Luckily it was just an old laptop I’d installed Linux on to mess around and learn, no real damage done
