  • I agree with OP here, these results are not great.

    OP searched for the redis docker image, not a tutorial on how to use it, not a tutorial on why redis should be run in docker, and did not search for redis docker docs. While these are relevant, they should be further down, not the top result. DDG gets this right, and I’m pretty sure other search engines do too.

    For a total newbie, these results are probably OK, but for a technical person who knows what they want literally as they type it, Google’s results are (excuse my french) simply shit. DDG is miles better at handling this stuff, and they don’t need your personal data to do it well either.

    Edit: Just went and searched “redis docker image” in a private tab on Google, and the docker hub image for Redis is not even shown on the first page of results

  • Dang, that thing is the bees knees!

    Would make more sense to replace just the batteries rather than the whole unit IMO. Looks like it takes standard 12v 7Ah sealed lead acid batteries, so should be doable for under $120 (if you buy them individually and use the existing battery harness)

    I have three other UPSes, but none of them are as good as yours lol:

    • APC SUA1500RM2U - was a great online rackmount unit, stopped using this a few years back because of its tendency to overcharge batteries without a charge controller ADC calibration mod. It wrecked my last battery pack bad 😭 plan to convert it to LiFePo4 and put it back into service 🤞
    • Zigor Ebro - cheap and cheerful line-interactive UPS for the modem, network switch and CCTV cameras. Switchover time is pretty much instantaneous, worth every cent paid and has kept my network up through many outages
    • Cyberpower UT650 - A temporary offline UPS to hold the server gear specifically until I get the APC back in service. Honestly not worth the cheap price, the switchover delay is long enough to shut off anything that’s not a server PSU with massive bulk capacitors

    Edit: fix bullet list formatting

  • Flash drive hidden under the carpet and connected via a USB extension, holding the decryption keys - threat model is a robber making off with the hard drives and gear, where the data just needs to be useless or inaccessible to others.

    There’s a script in the initramfs which looks for the flash drive, and passes the decryption key on it to cryptsetup, which then kicks off the rest of the boot mounting the filesystems underneath the luks

    I could technically remove the flash drive after boot as the system is on a UPS, but I like the ability to reboot remotely without too much hassle.

    What I’d like to do in future would be to implement something more robust with a hardware device requiring 2FA. I’m not familiar with low level hardware security at all though, so the current setup will do fine for the time being!
