Aperiodic, in this sense, doesn't mean that there aren't any bits that repeat. In fact, if you pick any patch of tiles of any arbitrary size, that patch will be repeated infinitely many times. What it means to be aperiodic is that if you slide the whole tiling over so that one of the patches aligns with the repeated bit, there will still be something outside the patch that doesn't align. Compare that with, say, a repeating grid of squares, where if you slide one square onto a different square then everything lines up, all the way to infinity; it's impossible to tell that it's been slid over.

Aperiodic tilings! Just a couple of years ago someone discovered a single tile (down from the set of ~20000 that was first used to prove that aperiodic tiling was even possible) that can completely cover an infinite plane without ever falling into a repeating pattern.

Does navidrome support Chromecast? I've had a hard time finding a self hosted music solution that will actual cast. I do have a public facing domain name with certs that, as far as I can tell, is working correctly.

One group chooses the algorithm and the second group chooses which side they get to on.

In practice this would require the second group to basically have a switch that switches all voters' preferences. So I don't think that's gonna work here.

It's a good game in general, but

Well, they also need things for their base to be afraid of. Gays. Trans. Immigrants. Urban crime. "Only we can protect you from the scary, scary things!”

Oh, and the second one.

If you don't care about the digits of pi being in base 10, there's also a formula that can be used to calculate digits at any position you want in hexadecimal without having to compute the preceding ones!

Is this why the second coming hasn't actually come yet? He's on his dieback?

This is not the same for all crypto currency, but a bitcoin represents a "proof of work". When people "mine" bitcoins, they are consuming computational resources, and when they find a bitcoin, it is a certification of the work that was done to find it that becomes the value of the coin. And then, as others as mentioned, people just agree that that work has a certain amount of monetary value. But the proof of work is what limits the supply and allows that value to exist. 3Blue1Brown has a really good video that goes into the technical details if you're interested.

No, half the country voted for this. Or failed to vote against it.

I went on a trip to Oslo and Bergen last summer. I'd love to go back; they're great places for mixing hiking and city exploration.

Sound cutoff issues (lemmy.world)
submitted 1 year ago* (last edited 1 year ago) by ProfessorScience@lemmy.world to c/pop_os@lemmy.world
 

Hello! I'm pretty new to pop_os and linux, but am trying to switch over from windows. I've been having some sound issues where it seems like sounds get cut off. It seems to most noticeable with something like doing duolingo from my browser (lots of short sound clips of words and such; if I click on words quickly, then spotify playing in the background will stop playing briefly). I've tried disabling sleep, as described by https://support.system76.com/articles/audio/, without luck. I've also noticed that I see errors listed in pw-top which sometimes correspond to sounds getting cut off. That is, sometimes I notice a cutoff without seeing an increase in the number of errors, but when I notice an increase in the number of errors it usually corresponds to something getting cut off.

Is there a way to see what the errors from pw-top are? Or suggestions for other things I should look into? I've looked at dmesg and systemctl status --user pipewire.service (and pipewire-pulse) but the only error I see is a nvidia-drm thing which seems to be innocuous. I've also uploaded my alsa-info results, if that's useful.
