MODERATORS
Way back before computers had sleep mode we were encouraged to shut it down when not in use to save electricity. I don't think Windows 3.11 had it. The first time I think I remember encountering it was Windows 2000, but correct me if I'm wrong.
Self-hosters:
My PC is never on when I'm not using it.
My server, however...
Server, as in singular? 😅
Well I have a VPS to run lemmy just because I don't want something that public near my home network but I haven't found the limit to my little i7 HP mini PC... Yet
MORE CONTAINERS
No redundancy? No high availability? No clustering? What are you even doing man? One server? Those are rookie numbers. You gotta bump those numbers up.
/s, obviously. You do you, and whatever works for your needs/budget.
Yeah I'm trying not to fall further down the rabbit hole at the moment. Want to get a big raid cluster going so I don't have to be so skimpy on my Jellyfin library but I have to stop myself everytime I start pricing parts out lmao
The call of the upgrades will claim me one day though

A thousand refrigerator psychers must be sacrificed so the frig emperor can live on in perpetual conflict with the gods of chaos: Frigidaire, whirlpool, Samsung and Slaanesh!
Fridges actually do rest. They cycle on and off as needed to maintain their desired temperature and on average only spend about 30% to 40% of their time "on".
I only found this out the other night because my fridge went dead silent for a long time. I thought it was borked, so I was peering deep into the freezer when I saw The Gates of Hell through the grate.
(Okay, so full disclosure, I had smoked some pot, but it totally looked like when Dana opened the fridge to Zuul before she was The Gatekeeper.) 😱😱😱
Anyways, turns out it was in defrost mode (which happens twice a day), and that involves some elements going orange or something. I know that's vague-- I looked it up, but as I mentioned, I was high, so I only kinda remember, lol.
Edit:
The refrigerator activates a heating element located near the evaporator coil. This element warms the coils, causing any ice buildup to melt.
You've hear of fever dreams but this here buddy had a freezer dream.

Thermal cycling is one of the biggest stressors electrical components can be subjected to. Leaving your processor on and at a consistent load massively improves the lifetime of the chip. So take THAT, mom!
Heat cycling is a huge stressor on any material. That's part of why diesel freight trucks tend to last well past a million miles while it's newsworthy if a passenger car makes it that long. How many times a week is your Toyota Corolla driving 10+ hours at a time? Most commonly, when you hear of a million mile vehicle, it was making long haul deliveries daily and was maintained at the correct intervals.

Fridges 100% die, they're made to now. If your fridge is really that old and you can manage it, NEVER get rid of it, tell your parents to leave it to you in their will lmao.
You will lose money this way, old refrigerators were way way more power hungry and you can easily expect to spend more than a new fridge within 5 years.
You can still get new fridges that will last for decades. It just won't be one with LCD screens, ice machines, in door dispensers, complex internal designs, etc. Every one of those things simply creates a cascade of new points of failure, and component materials of varying ability to deal with the stress of being a fridge. You can buy new, efficient, fridges that are nothing but a box that cools, and a box that freezes, with doors. They will last for decades if you don't do anything crazy, or your house isn't destroyed by a natural disaster.
Gimme a brand and a model name, internet dude

Just be sure to clear the lint off your coils every five years or so. Otherwise you're making the poor guy suck air through a shag carpet.
suck air through a shag carpet.
Welp, that's a new euphemism.
Old fridges never die. Modern fridges are more efficient but more break-y, can't have both.
Actually modern fridges are usually less efficient. But that's because they use refrigerants that are literally thousands of times less harmful to the environment.
Old appliances frequently used R-12 which is an damn nice refrigerant except it depleted ozone and has a GWP (global warming potential) of 10,900. That means 1lb of R12 released into the air causes the same amount of global warming as releasing 10,900 lbs of CO2.
Newer appliances use refrigerants like R134a which still works pretty well, doesn't deplete ozone, and only has a GWP of 1,430.
The newest appliances are more frequently using R-600a which is hard on compressors because it has a high head pressure and it doesn't cool quite as well. But it also doesn't deplete ozone and it has a GWP of just 3. The bigest downside of that one is that it's very flamable (it's isobutane) so the legal limit on how much residential appliances can us is very low.
Old appliances broke, but they were made to be easy to fix so our grandparents could just swap out the broken parts. I helped my dad replace the compressor on an older fridge as a kid and the heating elements on my grandma's toaster. I remember my dad taking me to some locally owned mom and pop hardware store where we could buy replacement parts for old appliances off the shelf. My parents still have the toaster, but that store closed down and new stuff isn't made to be fixable anymore (most likely due to planned obsolescence thanks to late-stage-capitalism).
On a tangent, when you think about it, throwing an entire toaster away because one heating coil burned out or throwing awag an entire fridge just because the compressor gave out is not rational. But if you tell people we should have the freedom to buy repairable appliances then they look at you like you are crazy. To me, it is the other way around. Sustainability isn't political or a luxury, it is an inevitabe, unstoppable force of equilibrium.
When it comes to refrigeration in particular newer appliances tend to break more frequently because they are using more environmentally friendly refrigerants. Old CFCs cooled really well with minimal work from the compressor. Newer fridges and freezers are more frequently using isobutane (R600a) because it doesn't deplete ozone and it's GWP (global warming potential) is 3 where the GWP of even non ozone depleting HFCs can frequently be in the thousands. The problem is isobutane requires higher head pressures to work properly and doesn't cool as well as older refrigerants so the compressors have to work much harder to get the same result.
Also when it comes to household fridges and freezers, they really aren't worth it to fix anymore. You need an EPA 608 cert to even touch refrigerants (in the US anyways). Plus you need a two stage vacuum pump and a recovery machine (amongst other things) both of which can easily cost as much as a new fridge. Then you need to actually have the skillset to remove the broken component and braze a new one in because everything uses brazed connections now to minimize leaks. Then you need to have the know how to properly recharge the system with refrigerant which when you're working with a critical charge of maybe 2oz of refrigerant is an absoulte pain. All in all, maybe if you are already an HVAC tech and had the tools and materials on hand you might barely break even fixing your own fridge or freezer.
When it comes to consumer refrigeration they can't be user repairable due to having to work with refrigerants and economies of scale mean they just generally aren't worth a trained techs time to fix.
! subscribe to fridge facts
but in all seriousness, very informative.. thx
There's a YouTuber (Technology Connections) who's really into heat pumps, which is the tech responsible for refrigerators and air conditioners.

My refrigerator was never the same after everything that happened in Yugoslavia.

Funny thing, when I moved in, my last apartment had a refrigerator that was made in Yugoslavia. It died.
Resurrect it
We couldn't get new parts from Yugoslavia, for some reason.
Resurrect Yugoslavia so you can get your fridge parts
Tis a noble endeavor indeed.
The fridge is a big pump, it needs to circulate... It's when it sits idle for too long that it risks death!
Glances over at my 1954 GE Combination that has NEVER been serviced outside of cleaning and replacing the light bulbs.
heh. my 15 year old frigid started making random groans the last couple weeks. far enough apart that i couldnt figure out where it came from. got lucky one day it moaned while i was close enough to yank open the freezer and see where the lever for the icemaker had accidentally got flipped to the on position. since i hadnt hooked up the water line to it, the groan was the pump sucking vacuum
Why not take the ice maker out so you have more freezer room, even filling that space with a bucket with ice will help the freezer stay colder easier if you don't use the space. Could save energy long term and make it last longer

My wife and I are on our third fridge in 35 years. But the furnace in her mom's house when we sold it 5 years ago had been running since the late 1970s.

We've had a GE fridge that's probably older than about 10 years. But you know, it's complicated enough that it feels like it's made to fail at some point.
Well, stuff stopped cooling but all the lights were on and everything else worked. It was really weird. We were thinking it might be a dead compressor or something. Crap, do we need a new fridge?
Nope! What basically amounts to a glorified computer fan with a fancier proprietary plug does all the work of distributing that cold air through the rest of the unit.
The proprietary plug is totally so they can sell it for $45, of course. Lol anyway, works like new!
Also get a dust mask and vacuum + blow out the back of your refrigerators, people. They get grooooss!!!
Ya. That black server fan in the frig is very common for the model of frig..also the little white resistance sensor on the coil tends to fall off of the tube sometimes causing it to defrost poorly. I like to swap them out when I'm doing the fan as a prophylactic.
The reason they use that fan is because it's super quiet and voltage can be regulated to it for different spin speeds which I turn is supposed to save energy.
The issue with the fan in and of itself is that it's inherently an aftermarket fan produced by an aftermarket manufacturer for GE. It's just junk.
