  • There is a med called Welbutrin which can be prescribed for quitting smoking and it works really well. It’s also prescribed as an antidepressant so one of my smoker friends was on it for that reason and they almost completely quit smoking without even trying to. Of course, it is not without It’s sideeffects but among antidepressants it is one of the usually best tolerated ones. I’m on it for my depression now and the only issue I have is that it can make me really anxious, but I’m also on nearly the maximum dose where for smoking cessation you wouldn’t be taking anything close to that amount.

    I was a refrigeration tech in a place that made high end refrigeration equipment. Fun fact, when some refrigerants get too hot, they break down into hydrogen flouride which forms hydroflouric acid when it comes in contact with water, such as the water in your respriatory tract. Acids taste and smell sour. Being that I normally worked with brand new equipment, I had never dealt with burned refrigerant before. This resulted in me wondering why the hell the refrigerant in an RMA machine had a sour smell when purged the lines on my manifold. Like the dumbass I am I wound up smelling a fair bit of that refrigerant trying to identify why it smelled sour before it finally occured to me that I had been practically snorting hydrogen flouride. One hospital trip, a few chest xrays, and an ECG later I wound up being fine. The next day I came back to work to find that my smartass boss had put a bag of sour candy on my desk.

    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.

    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.




  • 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.




  • 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.

    It’s actually really easy. You just bleed a whole bunch then consume foods and drinks without microplastics in them so your body regenerates new blood without microplastics. Then you wait for that blood to pick up some microplastics from you body and bleed a whole bunch again and repeat that process to keep reducing the amount of micro plastics in your body.

    The key part is to just make sure you aren’t being exposed to any micro plastics at all while you’re doing that which is basically impossible to do so good luck.
