  • 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!



  • 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 = 100k spools = $1M for the fishing line.

    Let’s assume every spool needs about 1 kite. That’s 100k 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 $0.02*5 + $0.10*10 = $1.10 per kite. That totals $1.10 * 100k = $110k.

    So using these estimates, this kite ring costs around $1.11M.

    No clue if it would actually work though.

    Edit: corrected a math error






  • 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.





  • I use both, since they do different stuff. I actually remote into my servers with wireguard, but I like to install tailscale as well as a backup. Since each device gets a unique tailnet ip, I can usually still connect even if I’ve fucked up some network config that breaks wireguard. ((If this is a security risk, someone let me know because I have no clue what I’m doing tbh.))

    Plus tailscale lets you easily see what devices are connected to the internet at a given time.
