Oh, speaking of scifi, I read another article (which I cant find now, unfortunately) about space walks: astronauts can't just climb into a space suit and exit the space station, because that would cause decompression sickness. They have to undergo about 24 hours of preparation, then spend time in a decompression chamber once they re-enter the station. I can't find the article I read atm, but here's one from space.com that talks about it:

About 24 hours before the spacewalk, astronauts undergo decompression, the same procedure divers follow when returning from the depths of the ocean to the surface of the water. Inside the space station, air is pressurized to the same degree as it is on Earth at sea level: 14.7 pounds per square inch, or 1 atmosphere.

But inside a spacesuit it's 4.3 psi, according to NASA, which is about the same pressure experienced at 30,000 feet (9,000 meters) above Earth. Experiencing a rapid drop in pressure from 14.7 to 4.3 psi causes nitrogen bubbles to form in the bloodstream and get stuck, blocking blood flow — a condition known as "the bends" or decompression sickness. To avoid the condition, astronauts camp out the night before in a closet-sized airlock while wearing their space suit so their bodies have time to adjust to the change in pressure.

e: Sandra Bullock would have died of decompression sickness pretty quickly.

Becoming an astronaut is a fairly romanticized career path, but there are a lot of less-than-romantic aspects to working 50 miles or more above the Earth’s surface. Case in point: just being in zero G makes the human body do all sorts of embarrassing things.

A new story from the New York Times exhaustively points out that living in space comes with all sorts of “bodily indignities” which should give even the most eager potential space explorer pause. It turns out, it’s not just deadly radiation or muscle loss due to weightlessness astronauts traveling to spots in our own solar system will have to put with:

In microgravity, however, the blood volume above your neck will most likely still be too high, at least for a while. This can affect the eyes and optic nerves, sometimes causing permanent vision problems for astronauts who stay in space for months, a condition called spaceflight-associated neuro-ocular syndrome. It also causes fluid to accumulate in nearby tissues, giving you a puffy face and congested sinuses. As with a bad cold, the process inhibits nerve endings in the nasal passages, meaning you can’t smell or taste very well. (The nose plays an important role in taste.) The I.S.S. galley is often stocked with wasabi and hot sauce.

These sensory deficits can be helpful in some respects, though, because the I.S.S. tends to smell like body odor or farts. You can’t shower, and microgravity prevents digestive gases from rising out of the stew of other juices in your stomach and intestines, making it hard to belch without barfing. Because the gas must exit somehow, the frequency and volume (metric and decibel) of flatulence increases.

Other metabolic processes are similarly disturbed. Urine adheres to the bladder wall rather than collecting at the base, where the growing pressure of liquid above the urethra usually alerts us when the organ is two-thirds full. “Thus, the bladder may reach maximum capacity before an urge is felt, at which point urination may happen suddenly and spontaneously,” according to “A Review of Challenges & Opportunities: Variable and Partial Gravity for Human Habitats in L.E.O.,” or low Earth orbit. This is a report that came out last year from the authors Ronke Olabisi, an associate professor of biomedical engineering at the University of California, Irvine, and Mae Jemison, a retired NASA astronaut. Sometimes the bladder fills but doesn’t empty, and astronauts need to catheterize themselves.

If the Cheneys of all people can jump ship, there’s hope.

I swear that spite and hatred must fuel longevity somehow. Kissinger made it to 99.

Pre-game coverage just started on ABC (I’m streaming it now).

He brings up Afghanistan?

She brings up his own admission that it was his own doing:

speaking at a rally on 26 June [2021, he] even stated that he “started the process” and claimed Biden “couldn’t stop it” if he “wanted to”.

Aw, now I wish I hadn't broken out the grater. Who will carry this ring to Mordor now?

Yes, this. Ore-Ida.

I got fed up with this shit and left. That should prove I'm human.

Fridge fridge hamburger truck truck... ??? What's the blue thing? I thought hamburger would be the answer, but it isn't? I just get the same captcha with the hamburger in a different place. WTAF is happening? And what's the blue thing? I answer and it refreshes with the same icons in different places. I AM HUMAN!

I’m not sure there’s a correct answer to that, because the answer is technically yes, I think I’ve been inappropriate sometimes but also yes, I’ve been been told to stop sharing by several peers as an adult in several different settings, but not by anywhere near the number of peers I had.

Logically, it doesn’t make any sense to let a tiny percent outweigh the majority. It doesn’t feel nice, though.

e: tried to clarify

[–] [email protected] 5 points 1 year ago

Thank you, that helps.

or it's some stupid power play thing where they think you're trying to challenge their status.

Although if it’s that, I’ll never figure it out. I can’t even begin to relate to that enough to identify it.

It’s worth trying, even if you think you’ll end up cancelling anyhow. The last time I had to deal with them, they dropped my monthly bill from $150 to $80 for their highest speed broadband, and now I get roughly 1gb download speed for $80/mo. (eta in case it’s not clear: that wasn’t based on hypothetical sale prices; I’d been paying $150/mo out of pocket for half the speed; I now pay $80/mo for double the speed I had been getting.)

Your results will probably vary – I have 25 years of uninterrupted customer loyalty to leverage. (eta: not like I have a choice where I live, it’s them or dial-up, but their international agents don’t know that lol).

🤞

e: also if you follow this blueprint, let us know if it works. I didn’t come up with this pattern, but it did work for me.

 

From the article:

Ant-attended aphids are known to excrete high-quality honeydew when ants are present. Ant attendance has a negative effect on the growth and reproduction of the attended aphids. Therefore, trade-offs should occur between the quality of honeydew and the growth and fecundity of aphid individuals. Thus, if attending ants prefer the morph excreting a high-quality honeydew, such trade-offs and resulting competitive interactions are expected between the color morphs in M. yomogicola. The morph excreting high-quality honeydew is known to have a lower reproductive rate than the other morphs[9,10]. This fact implies that if the attending ants prefer one morph, this morph is expected to excrete high-quality honeydew. Note that any such difference between morphs leads to the exclusion of the inferior morphs. Surprisingly, nearly all colonies consist of both green and red morphs in the field.

 

I’ve exhausted things I can sleep to on Netflix, and it’s literally impossible to sleep to things on Prime (so I barely watch anything there; it’s not worth falling asleep to something I like, since I might be punished for it), so I’ve started putting on YouTube in the evenings since it won’t wake me with silence at 4am.

I’ve a few voices I love listening to, but I’d like even more.

Which YouTubers do you recommend who:

  1. Have smooth, hypnotic voices,

  2. have content that won’t give me uncomfortable dreams (I’m a very visual, realistic, and impressionable dreamer), and

  3. have channels I’ll want to listen to when awake? (eta I like sciences and news mostly, a bit of fiction (scifi, horror, nf), gaming, other nerdy things, but never romance, pop culture , or reality tv).

I kinda need all 3.
