- Comment on An Alternative to Lasik — Without the Lasers 1 week 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 4 weeks 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.

Oh yeah, by all means report on this case to the psychologist community. I’m saying you shouldn’t just spread this everywhere and call it “news”; There’s too many stupid people willing to do shit like feed their kinds bleach because they think it cures autism or some shit.
- Comment on Woman says faecal transplant saved her and could help many more like her 4 weeks ago:
Yeah there’s too much pseudoscience around mental health to take one anecdotal case seriously. I’d even go as far to say that publishing this as “news” is pretty irresponsible.
Come back when you have a peer-reviewed study with dozens of test cases please

- Comment on Kids are making deepfakes of each other, and laws aren’t keeping up 1 month ago:
I agree with the other comments, but wanted to add how deepfakes work to show how simple they are, and how much less information they need than LLMs.
Step 1: Basically you take a bunch of photos and videos of a specific person, and blur their faces out.
Step 2: This is the hardest step, but still totally feasable for a decent home computer. You train a neural network to un-blur all the faces for that person. Now you have a neural net that’s really good at turning blurry faces into that particular person’s face.
Step 3: Blur the faces in photos/videos of other people and apply your special neural network. It will turn all the blurry faces into the only face it knows how, often with shockingly realistic results.
