Huh for some reason I’d never considered that fact that the songwriter would have no idea what a star consisted of. Just a mysterious light in the sky.

- Comment on An Alternative to Lasik — Without the Lasers 2 months ago:
In the body, the shapes of many collagen-containing tissues, including corneas, are held in place by attractions of oppositely charged components. These tissues contain a lot of water, so applying an electric potential to them lowers the tissue’s pH, making it more acidic. By altering the pH, the rigid attractions within the tissue are loosened and make the shape malleable. When the original pH is restored, the tissue is locked into the new shape.
In this work, the team constructed specialized, platinum “contact lenses” that provided a template for the corrected shape of the cornea, then placed each over a rabbit eyeball in a saline solution meant to mimic natural tears. The platinum lens acted as an electrode to generate a precise pH change when the researchers applied a small electric potential to the lens. After about a minute, the cornea’s curvature conformed to the shape of the lens — about the same amount of time LASIK takes, but with fewer steps, less expensive equipment and no incisions.
Sounds cool! Hope it continues to do well in further testing.

I think chances are higher we all die, the microplastics get embedded in a layer of rock worldwide, and nature moves on without us. Evolution is way too slow to keep up with maade horrors.

For Jellyfin? You really don’t need much. A raspberry pi can run jellyfin if you don’t have a transcoded format. My main server is only using a 6th gen i3, and Jellyfin runs perfectly.

Could spider silk be the solution to this?
Super lightweight and very strong. Plus it’s springy, so that can even out any sharp tugs on the line.

I assume you meant to say they’re not above the equator, which I didn’t actually know until now.
We can find the new length by simply multiplying the equator total by cos(latitude), since circumference is linear to radius.
For subtropical jet streams, latitude is around +/-30 degrees, so our adjusted price comes out to around $950k.
For polar jet streams, the latitude is around +/-60 degrees, bringing the price to $555k.
Extra note: The jet streams can reach speeds of >100mph, so I don’t think our poor little toothpick and plastic film kites will survive!

This also assumes the time you spend making 100k kites is worth nothing to you
- Comment on xkcd #3121: Kite Incident 2 months ago:
Doing some quick math here:
Circumference of the Earth is about 24k mi = 44M yds.
The cheapest fishing line I could find online (from Amazon) (I didn’t search very hard though) was $10 for 440 yds of line. To circle the Earth, you’d need 44M / 440 = 10k spools = $100k for the fishing line.
Let’s assume every spool needs about 1 kite. That’s 10k kites. You can find kites online for like $5 each, but the cheapest way to get a kite is probably to bulk order wooden sticks and plastic film and make them yourself. Let’s do the math on that.
Assume each kite requires a generous 5 ft^2 of film, and 10 ft of sticks. I found some bulk plastic film rolls online (from McMaster Carr) for about $0.02 per ft^2, and some wooden marshmellow sticks (on Amazon) for about $0.10 per foot. That makes $0.025 + $0.1010 = $1.10 per kite. That totals $1.10 * 10k = $11k.
So using these estimates, this kite ring costs around $111k.
That’s way more affordable than I was expecting. No clue if it would actually work though.
