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.
I run prime95 24/7 on my AMD FX-9590 to keep it at a nice stable temp. Plus it means I also don't need to heat my house in the winter. Gotta love a tdp of 220W.
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.
Ah, yes. Because the only thing that would improve my pizza eating experience is the risk of breaking a tooth on a seed.
It's common resturant lingo but fast food is completely different from resturant work. Also "86" literally has the same number of characters as "no". They could have put down "no cherries" with the exact same ease. They decided to play a stupid game so they won a stupid prize, a stupid amount of cherries.
Oh, cool! When you said parasitic wasp my brain immediately pictured a tarantula hawk wasp.
Exactly. Nothing with shared credentials should be directly accessible to someone off site to begin with. Either way things went down they have a security hole you could fly a blimp through. Either they aren't revoking credentials properly or they have eternally facing systems using shared credentials.
Gonna be honest chief, I would sooner burn my house down than live with wasps.
But thinking about it, I'm willing to bet that house centipedes would clear them up too. Those voracious little buggers eat everything.
Exactly, personally those perfectly chiseled corners of Colorado get me all hot and bothered.
Yeah, the proper time to revoke credentials is before they even know they're getting fired. At all the places I worked, the first sign that someone was getting fired would be that they're suddenly unable to access anything.
Yeah, that's on the customer. If you write that you want a bunch of fuckin cherries then you're getting a bunch of fuckin cherries. Now go eat the pile of cherries you ordered.
Wait, caffeine actually keeps you all awake? It usually just makes me more tired. I only drink it to keep the withdrawls at bay.
This is the exact feeling I always had with my big ass tool box on my tiny ass truck. "Hold on, y'all need a kitchen sink? I think I got one in here." I still remember how good it felt the exactly one time I had all of the tools required to do a parking lot clutch swap just on hand in that thing when a friend blew their clutch up.
MN is not a stand your ground state. If you are threatened in public then you have a duty to retreat if able. However, MN is a castle doctrine state so if someone threatens you on your property then you are perfectly clear to use any reasonable means up to and including lethal force to defend yourself and your property. So your initial idea only works in MN if the threat took place on his own property of if he is unable to get away from the threat.
I can think of no better way to all but guarantee you get shot than to point a gun at someone else.
Foraging in your whitetail deer fursuit durring hunting season is about the only way I can think of.
Generally speaking, even if your state doesn't have brandishing laws, pointing a firearm at someone is still considered assault. Assault is the unlawful attempt or threat to cause harm to another person.
Grain moth larva. Good luck. The damn things are a pain to get rid of once you have them. You'll want to pitch any food that isn't 100% air tight sealed (bags or boxes of cereal, rice, flour, sugar, noodles, etc.) and then clean out any cabinets really well to make sure you get rid of as many eggs as possible. After that make sure you don't leave any food unsealed for the next few months because odds are they will keep popping back up ocasionally for a bit and if they can get into anything when they do then the infestation starts all over. As far as infestations go they aren't the worst to deal with but they are anoying.
How the hell do you bash someones head in with an axe without making enough noise to wake anyone else in the house? Especially when it's a couple, like how do you not immediately wake up when the person sleeping right next to you gets their skull caved in?
I grew up next to a railroad crossing so I can sleep through train horns but I doubt even I could sleep through that.
Wait... He crushed HUNDREDS of people with a bulldozer in less than 6 months‽ What the actual fuck.

I've been letting this grassy plant slowly take over my yard and I haven't been able to actually identify it. It has white flowers in late summer that bumble bees absolutely love. It smells like onions when you cut it and it tastes like onion as well except maybe slightly more mild.

How are you supposed to decide where to get care for emergent conditions? Where is the dividing line between "just book a clinic visit", "head into urgent care when you get a chance", and "go inmediately to the ER"?
So this is a question I've always struggled with and it makes me feel very dumb especially because I literally am a EMR. This feels like something I should know. But at the same time I have also called to book a clinic visit before and had the scheduler tell me to go to the ER immediately only for it to wind up being nothing.
Certain things are obvious of course. Like if I need stitches or there is other major trauma then I know to go to the ER. If it is something like a concerning infection then I know urgent care can sort me out. For a skin rash that's probably a clinic visit. If urgent care is closed and it can't wait then default to the ER. But there are also the issues where I genuinely don't know on what side of the line they should fall. This is especially an issue for things that have been going on for a while which I know could be severe but almost certainly aren't.
For example (not asking for medical advice) I've been having repeated extended periods of heart palpitations for the past 2 weeks. At first I just chalked it up to screwing up my anxiety med schedule while I was on vacation because my med situation does cause heart palpitations if I screw it up. So I didn't think much of it at first but now I've been back on my meds properly for 2 weeks with no change. So, that's cardiac symptoms which in a patient would make me tell them to immediately go to the ER just to be safe. But at the same time it's been going on for 2 weeks and it's probably just some vitamin deficiency or something so it probably wouldn't kill me to wait a week for a clinic appointment (no walk in clinic here). Do I split the difference and go to urgent care? It's like schrodingers medical issue, it's both the worlds most benign thing and a symptom of immediate death until someone looks into it, so how do I know who should open that schrodingers box?
It seems like there has to be some easy dividing line on how to know which one to go to that I just don't know.
Edit: In USA, because that probably matters here.
So I recently upgraded every component in my PC to be fairly high end, except I didn't have the money to upgrade my GPU at the time so I was running with my old GTX 1070 for a while. Today I had some extra money so I finally got around to picking up a RTX 4070 super.
While installing it I just discovered a slight hitch in my plan. My primary monitor is 4k and uses display port so it isn't an issue. But my secondary monitor is an ancient 1080p monitor which only uses dvi and vga. The 4070 super only has display port and HDMI slots. I've been running with two monitors for so long that I don't know if I can stand going back to a single monitor.
It's already too late to run out and pick up an adapter so my plan for now is to install both GPUs in my PC and just pull the 1070 back out whenever I get around to getting a new secondary monitor or an adapter. Will a RTX 4070 super and a GTX 1070 both work in the same PC or am I just stuck with one monitor until I can get an adapter?
I like the bit of minty burn and it doesn't feel greasy afterwords like the non-alcohol based ones I've tried.
A friend of mine just sent me this picture and said someone they knew just got a capybara. I informed them that that definitely isn't a capybara. Now neither of us know what it is. It kinda looks like it's in the uncanny valley of the rabbit species. Is it just a fucked up looking rabbit?
Seriously, what sadist saw a flat PCB surface, flat pick and place machine heads, and said "lets create a round component"?
Joking aside I am genuinely curious what advantage the MELF design actually offers. I know they're a pain to get a machine to place properly, they have more solder flow issues than components with flat leads, and they seem like they would be harder to manufacture too. So why a round component? Anyone here have any insight on why they even exist?
So I just discovered that I have been working next to the waste of oxygen that raped my best friend several years ago. I work in a manufacturing environment and I know that you can't fire someone just for being a sex offender unless it directly interferes with work duties (in the US). But despite it being a primarily male workforce he does work with several women who have no idea what he is. He literally followed a woman home, broke into her house, and raped her. Him working here puts every female employee at risk. How is that not an unsafe working environment? How is it at even legal to employ him anywhere where he will have contact with women?
So I'm planning out a bathroom remodel and part of that is replacing the vent fan because currently mine is just venting into my attic (no bueno). I know normally bathrooms are vented out through the roof but my bathroom is on an exterior wall so I was wondering if I could just vent it out the side of the house. I'm going to be ripping open that wall anyways and I would much rather cut a hole in the side of the house than run a vent pipe up through the roof.
Also I'm in Minnesota if climate is a concern.
I work on equipment that runs off 3 phase 208V but it uses uses a transformer to drop it down to 120V for most of the controls. On this equipment I noticed that there are two fuses on the lines exclusively feeding the 208V side of the transformer and a fuse directly off of the hot side on the 120V side of the transformer.
Isn't the fuse on the 120V side of the transformer redundant? From my understanding, if there is a current spike on the 120V side of the transformer then that will cause a current spike on the 208V side of the transformer and immediately blow those fuses anyways. Is this just a certification thing where that redundancy is required? I'm in the US but this equipment does also get shipped to various overseas locations. Also, while it isn't standard, this equipment is capable of passing a TUV inspection if a customer requests it so I'm not sure if the potentially redundant fuse is just a TUV requirement.
I've been seeing a lot of users from alien.top commenting in various threads (mainly sports) lately. They only caught my attention because they are all flagged as bots and I typically manually block most bots (not all because there are some I like). For every one of them their entire post history consists of 1-2 comments or posts. When I took a look at that instance there is nothing there at all and it also shows no users. The comments look human enough but I guess I wouldn't be surprised to learn that all the comments are LLM generated. Is alien.top just someones LLM experiment or is something else going on here?
So I'm a refrigeration tech with some electronics manufacturing experience. But I've never combined the 2 skillsets so I've been toying with the idea of building a large vapor chamber to cool a computer via direct immersion in a refrigerant. I know its about as far from practical as you can get but it sounds like fun.
Ignoring all of the many many other problems with doing this for now the one thing I'm not sure about is how well the electrolytic caps on the various components would survive. I would need to pull a fairly hard (500 micron) vacuum on everything before I charge it with refrigerant. I know most electolytic caps aren't vacuum rated but I'm not sure if that just means you can't have them operating in a vacuum or if they will immediately pop if you just subject them to hard vaccum period. Additionally while I am planning on using a low pressure refrigerant (probably some R-123 substitute but I'm definitely still working on that part) the components would all still be subject to pressures of up to about 20 PSIG at the high end. Beyond that point I would probably have an active cooling system kick in just for safety sake. I'm not sure how well the caps in particular would survive being immersed in a liquid under 20 PSIG pressure.
Does anyone here have any experience subjecting electrolytic capacitors to hard vacuum or elevated pressure? At what point do they just pop?
So I just went and donated blood again and durring the recovery period it occured to me that it takes quite a bit of work for your body to regenerate that lost blood volume and the actual blood cells. Regrowing that many cells seems like it would be fairly energetically intensive. So how many calories does producing all those new blood cells actually consume? Is there even a way to know that?
