Surely there are pumps designed to handle pumping cryogenic liquid, though probably also expensive. But the way I'm thinking it through I see it introducing a new logistical challenge, at least for the high nitrogen purity he seems to be prioritizing. If you're going to suck liquid out you'll need to still balance pressure in the tank. The Dewar must have been designed with some kind of system in mind to balance the pressure (maybe from a similar gas air separation system to the one he's using), or it wasn't designed with maintaining such a high purity in mind in which case you could balance pressure with ambient air as you pump the liquid out.
Honestly it's weirder to me that it wasn't designed to be used with some moderate level of pressurization. Pressurizing it (positively or negatively) seems to make it much easier to use.
As for the output stream, I think part of the issue is a lot of his liquid is probably vaporizing once it's in contact with the hose walls. I think if he ran it long enough the liquid flow rate will probably go way up as the hose chills down. For being a remarkably clever accidental mechanical engineer, he seems overly ignorant of the heat transfer at play (such as most of his initial liquid vaporizing at the bottom the Dewar for the first hour until the Dewar walls cooled down to match the temperature). Like, surely he realizes things need to cool down and it's going to take a while because he's going to such low temperatures, right? O.o Maybe he's just doing a bit.

It looks like about 4 psi gauge pressure was just enough to overcome gravity up the siphon tube. I don't think suction is really an option is this setup as it would require pulling a vacuum on the Dewar instead (which at that point positive pressure is probably just as dangerous and doesn't require an extra piece of equipment), or submersing a pump that could handle the cryogen pressure at the bottom. I think for the setup he has, his only option is to use a different Dewar that can handle higher pressurization which would give him a higher flow rate out of the hose.

Maybe at one point I wouldn't have hesitated to send a company a picture of my gov ID, but anymore I'd just accept a ban and move on becuase precisely this risk doesn't seem worth it. Wild. 🙃

I have a friend who raves about the memory function and remember seeing something on here about how ChatGPT gets better with use because of the memory developing, however to me it's an anti feature. Especially as OpenAI tries to figure out how to make money I'm not inclined to voluntarily feed a personal data repository.
I've also found that when using it for coding, if I encounter a bug after a while of work it has trouble breaking away from what it's already tried. If I copy the script into a fresh conversation, outline what the code does and highlight the issue I'm encountering, it can usually move towards a fix pretty quickly. There's a lot of benefit when using an LLM as a tool to be able to get a fresh conversation without any additional context that might be pushing the conversation in a specific direction.

Comment on Earth is getting darker and it’s changing the planet’s climate balance in ~enviro

For me it always important to point out that reduced reflection due to cleaner air is a net positive for us. Just because some polluting aerosols reduced the rate of global warming early on does not mean that that the abundance of aerosols from our emissions were a good thing. I think a certain crowd has a knee jerk reaction to think we should be putting more aerosols into the air again rather than continuing to reduce the other things we're doing causing atmospheric warming. And I think articles like this should be clear that this is an unintended side affect of something positive we've done and not a bad thing.
Slight tangent because this is not what the article is about: Geo-engineering folks seem to want to overlook decades of gains in pollution reduction and cleaner air when they start talking about dumping chemicals into the atmosphere on purpose. Which I personally find baffling because it's the same chemicals we've worked so hard to keep out of the atmosphere because of things like acid rain. -_-

The broken windows theory, famously a strong foundational example for your argument. 🤦♂️ I'm not rooting for a military coup, but there's no way every person in that room, most of who are at least an order of magnitude more competent, isn't trying to figure out how to wrestle control back before it all goes sideways, right? ... Right?

I have Splatoon and played it a few times. I think you need online play to make it worth it, however Ive had a lot of fun every time I've picked it up for a couple hours. I think that one has much broader age appeal. Definitely worth considering.

Second:
Doesn't look like anyone has mentioned Nintendo Sports for the Switch, so I'll throw that out as a recommendation. I've really enjoyed playing the games with a few friends, and despite not living up to Wii Sports, I think is still a great game and good value. The controls might be a bit hard to pick up for the 4 year old, but the 15 year old shouldn't have any trouble.You can play up to 4 people locally and don't need the online play to enjoy everything (though online is the only way to earn more outfits and cosmetics unfortunately).
Luigi's Mansion 3 might be good for the younger, but it's essentially a vacuuming simulator so your mileage may vary. I did play the whole thing and remember getting stumped at a couple parts.
Links Awakening is a great remake and thoroughly challenging.
The little one might love Echos of Wisdom. It's very cute and I don't think every particularly overwhelming. I'm about half through and it definitely feels more geared to a young audience.
Super Mario All Stars might be a good contender. You get 3 great classic games. The controls are a little weird, but I think Super Mario Sunshine is the best and it's worth picking up just for that alone.

The only time the experience isn't great is when I get near a busy road. It can be pretty hard to hear a podcast clearly over road noise, but that only accounts for like 2% of the time I'm wearing them. Their sound reproduction for voice is pretty good so podcasts and audiobooks are clear.
I can usually wear them for a few hours and often forget I have them on if I paused what I was listening to. I do occasionally get some irritation at high volume after a couple hours of listening. I think the small vibrations are enough to irritate the skin wear they rest if I need them at high volume for some reason.
I have not enjoyed using them at the gym. It's usually too loud between the overhead music and background noise to actually hear what I'm listening to. So that's one use case they don't work for.
I do like them around the house occasionally too. I'll wear them while doing quite chores or cooking if I still need to be able to intermittently hold a conversation with my spouse. They're easy to pause and unpause by scrunching the side of my head into my shoulder to hit the pause/play button. Great if I've got food and stuff on my hands since I don't need to touch them to pause them. The mic is apparently decent enough to talk on if I've gotten a call while using them too.
I have a pretty wide variety of earbuds and headphones that I use for different occasions and I'm definitely very happy to have a pair of bone conducting headphones to reach for.

Comment on California's next energy experiment is happening above aqueducts, reducing evaporation and increasing solar panel efficiency in ~enviro

Assuming a nominal efficiency of 20%, that's at a bare minimum 20% less solar heat reaching the water. But it'll be higher because the panels reflect a good portion of that radiation not absorbed. And the IR that they re-emit underneath from the heat will be substantially lower energy. And I'd bet the cool air above the water creates a bit of a breeze and keeps the panels much cooler. So without digging out a textbook I'd take a ball park guess at the panels reducing heat gain on the water between 50%-70%. The effects at play seem pretty substantial, but this is an off the head guess so that it for what it's worth.

Can't believe you can still run it in a browser. I assume it's been updated somehow?
My best guess is it would probably introduce a significant thermal bridge at the part of the tank you would want to stay the coldest. Heat would be able to conduct along that out let's pipe wall straight to the bottom of the liquid and significantly reduce its insulating characteristics.
