@kissane It was @grantimatter who introduced me to it. (I haven’t been keeping up lately but I’m looking forward to catching up eventually.)

someone who is good at optimization please help me
Like if you see something real and find yourself wanting to think or say “Haha, just like in the movies/books/longform fiction podcasts”, interrogate that impulse at least medium-hard.
A good behavioral rule of thumb, in my experience, is to avoid reflexively comparing real life to entertainment.

Nothings as analogous to human constructions as capstones, but there is intentionality in grain placement.
“We hypothesized that the ants could sense these force chains and avoided digging there,” Andrade says. “We thought maybe they were tapping grains of soil, and that way they could assess the mechanical forces on them.”
@todrobbins @nelson The saved stream is also super crunchy at the left edge, where new pixels appear, while the YT player handles them gracefully.
@todrobbins @nelson The ISS stream is live again, and playing in the browser next to vlc playing the yt-dlp stream (with the settings above) shows pretty clear differences. The yt-dlp stream is oversharp on I-frames but struggles between them; it clearly isn’t good at the translational motion.
@nelson No no, I’m over my head here.
@nelson Meaning: the 311 stream that it writes to disk does not in fact have the advertised bitrate.
@nelson I know about them but it’s possible I’m using them wrong. I picked a terrible time to post this, because the stream is both off and on the night side right now, but if you run that when it actually works, it seems to be much lower-quality than what plays in a browser at the same time.
This is what I’m running:
yt-dlp --user-agent "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:124.0) Gecko/20100101 Firefox/124.0" --cookies-from-browser firefox -f 311 "https://www.youtube.com/watch?v=P9C25Un7xaM"
I assume the problem here is that YT runs stuff browserside to negotiate up to the good stream, but I don’t know.
Any tips on saving a YouTube stream (specifically, the ISS camera feed)? What yt-dlp saves is much lower bitrate than what I request it to fetch, and this seems to be a known bug of sorts.

It’s a really difficult time to be raising sponsorship for a tech-industry adjacent community event! We’re still seeking sponsors for @emf this year, to help us cover live talk transcription, on-site childcare, transport, and expense support for speakers, artists, and attendees.
If you’re interested or know someone who is, I’d love to hear from you. More info at https://emfcamp.org/sponsor 💖#emfcamp
