  • The answer for your question is ‘no’.

    You’re never going to reduce power usage substantially by swapping PSUs, because there’s just not enough efficiency gains to be had even if a Pico PSU was more efficient which they really aren’t.

    You say the hardware is ‘nothing too different’ but you mention ddr4 vs 3, which makes me think the Dell is a generation or few older which could easily impact power draw by 10w.



  • Yeah, I just mentioned it because OCI is kinda wonky and requires some static routing stuff in the iptables on the host to have the platform work as intended (which, as far as I’m aware, no other hyperscaler does), which strikes me as really really lazy engineering, but I’m just a simple computer janitor so maybe I’m wrong there.

    The most infuriating thing at my last job was people sending in a ticket freaked out that their database was stolen and ransomed, and us going ‘Well, we sent you 15 emails over the last 3 months telling you that you had the database open and improperly secured, so what exactly are you wanting us to do now?’



  • That’s not really the right approach on OCI, unfortunately: if you just flush the rules you also break a lot of their management plane.

    You’d want to modify the /etc/iptables/rules.v4 and rules.v6 files to add any rules you want to load on boot (and, of course, if you just flush the rules without saving them, then it won’t persist and a reboot will break things, again).

    It’s an arguable benefit: I’m a fan of having the security policies AND iptables sitting between me and doing something stupid, but I also spent most of the last decade dealing with literally thousands and thousands of compromised hosts that just whoopsie oopsed redis/jenkins/their database/a ftp service in a publicly accessible state, got hacked, then had the customer come crying to us asking why we didn’t keep them from blowing their foot off - which, basically, is what the OCI defaults do.




  • If you go old PC and use it for Jellyfin, you probably want hardware that can do accelerated video transcoding so you probably want to aim for 8th gen or newer Intel CPUs (with integrated graphics), because that gets you 10bit h265 transcoding, which I’d say is probably the bare minimum you should aim for these days.

    Granted that’s 5 or 6-year-old hardware, so it’s hardly new, but it took me a bit to figure out why in the world the transcoding performance and quality sucked and what’s supported where and at what gen of hardware is… hilariously unclear.


  • The IBM name, build quality, warranty and whole nobody-got-fired-buying-IBM helped, but don’t undersell 80 column text mode: if you wanted to do Real Business Stuff, 40 column just didn’t cut it, which wrote off a LOT of the cheaper competition. CP/M machines could be 80 column, but they also weren’t required to as there was no default terminal expectation. You’d end up with close-but-not-quites pretty often, even on the upper-end of the price scale.

    And yes, the Apple II had 80 column mode, but again, it wasn’t exactly the cheaper option.

    IBM entered the market at exactly the right time, with the right machine, with the right features, at a price that wasn’t incredibly outside of reality and sold an awful lot of them.
