  • Did you measure voltage drop across the pump while it’s trying to start up? The voltage will only drop when there’s current being drawn. So with the pump off you would see full supply volts even on a highly resistive line. You could try lugging a battery down to the pump, and jump it to get it started, then remove the battery jumpers but keep the pump running on your main run, then measure the volts across the pump.

    Or you could try to measure the resistance of your wiring with your meter. You would disconnect it from your 12v source, then short the pump side, then measure the ohms across the pair at the source side. Also measure the resistance across your pump windings when it is disconnected, but with the switch on.

    I’ll throw out some example numbers. Say you have a pump that says it needs 6 Amps. Chances are the inrush current is more like 12A. If you measure across the terminals with the pump disconnected from power with the switch closed, you might measure around 1 Ohm. Now if you measure your very long supply line and get 2 Ohms. Then you would only get 12V/(1+2 )Ohms = 4 Amps through the whole system. With the pump drawing 4 Amps you would only see 4V at the pump terminals when it is already running.




  • Those are good addendums, but I’ll add one more qualifier to your nasal rinse suggestion. Never use tap water. Use only distilled water or water that has been boiled. Pharmacies also sell aerosol cans with saline solution, which is what I use for the convenience factor. Then you don’t have to worry as much about sanitized water and mixing up a solution. Saline rinses should also have at least half an hour of being upright before laying down. Don’t do a rinse then immediately lay in bed.

    If budget isn’t tight, all bedding including the allergy covers benefits from getting in duplicate so you can take your time with the laundry. I was a lot worse about washing bedding when remembering late in the day meant there wouldn’t be enough time to wash and dry before bedtime.


  • Sounds like you have already convinced yourself the answer is probably yes.

    You could also have a high sensitivity to dust mites. Talking to an allergist could help you narrow down what specifically bothers you. Allergy tests aren’t that big of a deal to have done.

    Before trying to rehome the dog, do your best to make your bedroom a dog free zone. Keep the door closed and don’t let her on your bed. Shower before bed and don’t touch your dog between showering and getting in bed. Wash your bedding often. Don’t ever sitnon or get in your bed in clothes that have been around your dog or on furniture your dog is allowed to lay on. An air filter can help, but is limited in what they can actually accomplish. Filters can help with dust that comes in through your hvac vents, but any sources of allergens in your room will easily produce irritants at a much greater rate than a filter can capture them.

    I’ll avoid specific medical recommendations, but I will list a few things worth checking out. Non-steroidal nasal sprays could help your sleep. Nasacort was the one recommended to me by a doctor. One lesson I had to learn with that is to not use it right before laying down. You need to give it time to drain. It does bother my stomach a bit, so timing it with a meal or snack can help. Pataday and opcon-a drops have both been helpful for me. Opcon-a does cause a temporary burning sensation. I would recommend starting with lower dose twice a day variants The extra strength stuff also hurts my stomach. (your eyes and sinuses drain down your throat.) Eye drops and nasal sprays are more targeted than tablet antihistamines so they can be a little more effective.

    You might want to ask your doctor about a sleep study. In my unprofessional opinion, I would suspect you are experiencing apnea.

    If you have a polyfill pillow, try switching to foam, or better yet buckwheat. Polyfill is a dust sponge. Every time you toss and turn it will release a cloud of dust right by your face.

    You’ve lived this long with your dog, so it’s worth trying to find ways of improving your sleep hygeine and symptom management before jumping straight to no dogs. Although, a no puppies after this dog rule could be warranted.

    As far as not having some of the symptoms you think should be present, chronic exposure vs acute exposure can have different reactions. If you are always mildly reacting to your dog, then you won’t experience some of the acute responses. (Again, not a professional)



  • All of the OP’s points could be said about church sermons as well, and yet there’s still thousands of church gatherings every week.

    So I think your point hits the nail on the head. People don’t go to these large gatherings because they’re looking for a presentation of convincing arguments, books and recordings are better for that. They go to experience the sense that they are part of something bigger than themselves. They want to feel like they are contributing to something important, and a large crowd all in unison makes them feel that way. Rallies aren’t meant to change minds, they’re meant to get the base excited to donate/ volunteer/ talk to anyone who will listen.





  • I definitely agree with you, however, I think needing to become self sustaining on earth is a goal that would be well served by trying to design a self sufficient system for mars.

    Earth is big enough that it’s really easy to forget we’re all in the same fish bowl. Entire cities can flush their shit down the river and as far as they are concerned, nothing bad ever happens to them. The scale of earth makes us blind to the problems our actions and methods cause. The ecosystems also do quite a bit to protect us from our own actions

    You can’t ignore externalities in a space colony. Everything must be accounted for. That is what makes it so difficult to design for. Any small amount of waste will still accumulate over time and eventually becomes a problem.

    The tighter scope and strict requirements of a space colony would make it easier to actually objectively measure how sustainable it is. You would know exactly how much external inputs you are delivering each year. We can then take the lessons and technologies that are absolutely required in a space settlement and use them to inform how to better be sustainable on earth. For example, solar cells used to only really be used on satellites, not because they were great on satellites, but because they were pretty much the only option that could stay operational for years. Now PV power generation is helping countries all over the world become a little more sustainable. The harsh requirements of space make us better at problem solving.

    I totally agree that earth is our only option for species survival though. Anyone selling Mars as a “backup” for humanity is either delusional or a con man. I think developing the capability to keep a settlement on Mars is a worthwhile endeavor, but there is no way for humanity to thrive there. Any large scale catastrophe on earth will still be more survivable in select pockets on earth than anywhere on Mars.


  • There’s no risk for a factory condition unit. This rumor started after people with units that had been dissasembled and reassembled had issues with vertical orientation. It turned out that it’s very easy to mess up the seals that keep the liquid metal thermal interface in place. So units that had been previously taken apart had liquid metal slowly leak, causing overheating and/or shorting.

    If you haven’t taken the cooler off the mainboard, using the vertical stand is just fine. I haven’t seen any evidence of factory assembled units suffering leaking. It does imply that user servicing of ps5’s is a bit risky, and you might need to be wary of used units where you don’t necessarily know the service history.

    To avoid unnecessary confusion, taking the covers off to add an m.2 ssd does not add any risk.

    Do you want some discouragement?

    Stainless steel is stains less not rusts never. You would need additional measures to keep the stand from degrading over thousands of years. Your local archeology department could give you some pointers on how to accomplish that.

    Or maybe you design the stand in such a way that the tungsten object is held firmly, but still easily visible in rusty stainless jaws.



  • I notice changes in sensory processing first. Reading becomes difficult and my eyes lose focus easily/take a long time to focus. I also notice a difference in my thought patterns. My thoughts start to kind of skip around. It becomes hard to concentrate on any single thing, but not in a distracted kind of way. I very much realize that this description is vague and probably doesn’t make sense unless you experience similar migraines. I do also experience visual auras, but those aren’t apparent until the migraine is about to become very painful.

    A full blown migraine manifests as sensory processing mapping to pain. Light and sound are unbearable even in relatively moderate amounts. One of the worst migraines I had led to the pressure of my head on the pillow making every hair follicle feel like a a needle poking my scalp. You don’t realize how much your brain autonomously filters out tons of sensory input to keep your focus on a very small slice of interest until the filters break down and let everything through.

    Over the counter pain pills do nothing for my migraines. Sensory deprivation and sleep are the only things that can actually stop a migraine for me. I have blackout blinds, a well fitting eye mask, and foam earplugs ready to go. Early detection is very important. If I act as soon as I notice the warning signs, I can usually avoid a full blown migriane. A large glass of water + darkness and silence will usually have me back up in less than an hour. If a migraine gets to the point of pain, I will need sleep to get rid of it and will still feel rather off afterwards. Also falling asleep with a brutal migraine is no easy feat. A catch-22 so to say.
