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

I’m in the same boat as @shnizmuffin, lab has been nice and stable and have nothing to contribute as of yet.

At the beginning of the migration I was popping in and out of r/homelab, but as it stands now I haven’t visited there in ages!

A post box would be the best option IMO, as well as another contact number. Those combined are more expensive than just purchasing the domain with privacy protection included though…

If you’re not asked to add whois privacy at the checkout in future, the registrar or domain owner probably don’t allow it

TIL, don’t know why I didn’t realise spirit levels are called “spirit” for a reason - it’s not colored water inside 😭

I have a slightly off topic question - that’s the first time I’ve seen the big boi mounted on the door frame instead of the door itself… is there generally a difference between this and mounting it to the door instead?

I assume it was mounted to the frame here because it’s not wooden

Mining motherboard+ 10g network cards= cheap network switch?

So with Crypto mining being less profitable and miners selling their rigs for cheap I thought how can I get my self a cheap managed network switch. I saw mining motherboards with 12 PCIe 2.0 1x slots(4gbit bandwidth) and tought hey if I plug in some cheap 10g 2port network adapters I can make my own network switch with exactly...

Surprised I’ve never seen this DIY approach mentioned anywhere or thought of it before 🤔 - usually people end up going for those mini PCs that have multiple network cards soldered to the mobo itself

Compared to an actual 10gig switch, the power consumption might be high (unless the network card drivers have been well optimised by the devs, offloading as much traffic handling as possible to the 10gig cards’ own CPUs). In this case just make sure you have a powerful enough CPU to handle that traffic, as well as handle that 4gig traffic traveling between the network cards over PCIe.

Some gotchas to look out for though:

  • PCIe lane wiring… are they going straight to the CPU, or are they going via the chipset (or slightly slower, a PCIe switch connected to the chipset). The mobo manual can advise on this, ideally you’d want something with as much PCIe lanes connected to the CPU directly to get the full speed.
  • Power consumption… touched on this earlier but one to be aware of, esp if you live somewhere where electricity is expen$iv€
  • Noise… you might need to buy a fan to cool down the network cards depending on your traffic, and how much the OS driver offloads to your 10gig cards
  • A backup… if you need to do changes to your DIY switch, make sure you have some way of accessing the internet
  • Bridging… there may be an ideal/recommended way to set up bridging for multiple interfaces on the same network card, to take advantage of hardware offloading, allowing you to get 10gig traffic between two devices even though the PCIe lane is just 4gbit
  • Traffic filtering… again just ensure your CPU can handle it, particularly for HTTP traffic. I only do filtering on DNS traffic due to having a weak CPU, works well enough to catch some ad/tracking services that employ nasty tricks to evade blocklists.

I only have 1gig hardware so can’t really provide comparisons :( however there’s a youtube channel called ServeTheHome that started measuring power consumption of almost all the hardware they test - if they’ve done 10gig switches recently then that should give you some pointers at least

UAW members being poor doesn’t really play any importance here in my opinion - if we were to use this way of thinking for protests, restricting them to only those directly affected/impacted by the subject of said protest, IMO there would either be no change or things could get violent.

If anything, you as a person in authority could easily silence the whole problem at that point by wiping out the protesters.

I think it is better for the people who care to do something, regardless of whether they are affected or not, since the alternative is for society’s most exploited people taken advantage of even more

One of the only MOPs in my village’s local authority meetings.

Use public transport as I’m against overdependence on cars - it’s futile because cuts are made anyway, and combined usage costs as much as owning a car to begin with. The buses are very comfortable and air conditioned though 👍

Voting for a difference, but the status quo stays the same because everyone here is being fed the same sweet talk by a government that has said on the record that they are not interested in building new housing while there is an ongoing shortage.

Taking part in temporary government funded schemes, set up with the intent to collect feedback guiding future areas of expenditure.

And much more.

It’s all a waste of time though, nothing changes as a result. I say the UAW have got the right idea for going for what will hurt the most. People living paycheck to paycheck deserve better than this, or even worse, those stuck in endless debt. Last year the energy costs around here were equivalent to buying a new PS5 every month.

We can can shout all we like into the echo chamber here about possible solutions - but is the everyday voter even educated about how any of the existing institutions work? Asking people on an online internet forum what they are doing in their community, in an elitist condescending tone, does nothing to further this IMO. A union doing things like this, is everything that does.

Ewwwwww you nasty 😭😭😭

Double dip! Insurance companies hate him!

I’m sick of working 12 hours

Longer hours I feel are better suited to an office, at least that way it’s not so draining with others around you

lemann ,

Nice compact setup 👌

lemann ,

Nice! Price increase not so bad after all then

lemann ,

Yep, depending on what app/site you’re using it’s called either All or Everything.

Should be near other buttons Local and Subscribed

Yaaaay a new community to sub to 😍

There’s an instance admin community that should be able to help out with technical issues !lemmy_admin

There’s a matrix groupchat with most of the big instance admins as members, but I don’t know a lot about it tbh. Also would recommend letting people know your subreddit is trying lemmy at !reddit , and there’s another specifically for people announcing new communities but sadly can’t recall the name at the moment

I haven’t had a look at your sidebar yet, but add rules for bots and the such as you wish - here the frequently seen ones are autotldr and pipedvideobot. There is also communitylinkfixer but I haven’t seen it in a while.

No idea of the best way to promote it on Reddit, aside from popping a link in your sidebar over there? May be worth checking out the reddit communities for the three major instances that have migrated most of their users from reddit - lemmy.one (PrivacyGuides), programming.dev (Programming), and lemmy.dbzer0.com (Piracy)
