    I used to use a plain text system, “encoded” in such a way that only I knew what the actual password was, and I kept it on Google Keep.
    But that for harder and harder to manage, coupled with, if I were to get run over by a bus, no one else would be able to access my accounts.

    Now I’ve been using Dashlane for a few years. Not just for passwords, but secure notes as well.

    Works seamlessly on all of my devices and zero complaints.

    Strap in friends, because this one is a wild ride.

    I had stepped into the role of team lead of our IS dept with zero training on our HP mainframe system (early 90s).
    The previous team lead wasn’t very well liked and was basically punted out unceremoniously.
    While I was still getting up to speed, we had an upgrade on the schedule to have three new hard drives added to the system.

    These were SCSI drives back then and required a bunch of pre-wiring and configuration before they could be used. Our contact engineer came out the day before installation to do all that work in preparation of coming back the next morning to get the drives online and integrated into the system.

    Back at that time, drives came installed on little metal sleds that fit into the bays.
    The CE came back the next day, shut down the system, did the final installations and powered back up. … Nothing.
    Two of the drives would mount but one wouldn’t. Did some checking on wiring and tried again. Still nothing. Pull the drive sleds out and just reseat them in different positions on the bus. Now the one drive that originally didn’t mount did and the other two didn’t. What the hell… Check the configs again, reboot again and, success. Everything finally came up as planned.

    We had configured the new drives to be a part of the main system volume, so data began migrating to the new devices right away. Because there was so much trouble getting things working, the CE hung around just to make sure everything stayed up and running.

    About an hour later, the system came crashing down hard. The CE says, “Do you smell something burning?” Never a good phrase.
    We pull the new drives out and then completely apart. One drive, the first one that wouldn’t mount, had been installed on the sled a bit too low. Low enough for metal to metal contact, which shorted out the SCSI bus, bringing the system to its knees.

    Fixed that little problem, plug everything back in and … nothing. The drives all mounted fine, but access to the data was completely fucked,
    Whatever… Just scratch the drives and reload from backup, you say.

    That would work…if there were backups. Come to find out that the previous lead hadn’t been making backups in about six months and no one knew. I was still so green at the time that I wasn’t even aware how backups on this machine worked, let alone make any.

    So we have no working system, no good data and no backups. Time to hop a train to Mexico.

    We take the three new drives out of the system and reboot, crossing all fingers that we might get lucky. The OS actually booted, but that was it. The data was hopelessly gone.

    The CE then started working the phone, calling every next-level support contact he had. After a few hours of pulling drives, changing settings, whimpering, plugging in drives, asking various deities for favors, we couldn’t do any more.

    The final possibility was to plug everything back in and let the support team dial in via the emergency 2400 baud support modem.
    For the next 18 hours or so, HP support engineers used debug tools to access the data on the new drives and basically recreate it on the original drives.
    Once they finished, they asked to make a set of backup tapes. This backup took about 12 hours to run. (Three times longer than normal as I found out later.)
    Then we had to scratch the drives and do a reload. This was almost the scariest part because up until that time, there was still blind hope. Wiping the drives meant that we were about to lose everything.
    We scratched the drives, reloaded from the backup and then rebooted.

    Success! Absolute fucking success. The engineers had restored the data perfectly. We could even find the record that happened to be in mid-write when the system went down. Tears were shed and backs were slapped. We then declared the entire HP support team to be literal gods.

    40+ hours were spent in total fixing this problem and much beer was consumed afterwards.

    I spent another five years in that position and we never had another serious incident. And you can be damn sure we had a rock solid backup rotation.

    (Well, there actually was another problem involving a nightly backup and an inconveniently placed, and accidentally pressed, E-stop button, but that story isn’t nearly as exciting.)

    This right here. Reddit started with very general based topics and only later did smaller niche subs take off.

    Lemmy will get there. It’s just a matter of time and it’s only been a few months since the Great Reddit Migration of '23.
    By this time next year, or maybe 18 months out, once instances become normalized and settled, with user tools to help find and organize them, Lemmy will then start to cause large dents in Reddit’s user base.

    Having your own router/access point can’t be stressed enough.

    And, you don’t even need their modem. Sure it’s an additional outlay of cash, but buying your own modem gets you a nice upgrade and no worries about someone connecting to the Xfinity access point that’s bundled in their equipment.
