    So if I post a meme to c/tenforward, people on mastodon and pixelfed can see it if they subscribe to @tenforward, is that correct?

    Yep! I’m not sure how it works for pixelfed but I think I remember something about text posts so I would assume it works the same there.

    Afaik the way to tell if a user is on Mastodon vs Lemmy/mbin/etc is if the instance part of their username is a path instead of a bare domain, it’s something like user@instance.com/users or something that includes “user” in the path, I can’t remember exactly and I can’t find an example but if you look at usernames enough you’ll find one.

    Edit: Actually maybe that changed because I found a comment from Mastodon and it looks normal just with a domain that you can see is a mastodon instance when you visit it, so idk ¯\_(ツ)_/¯

    Edit 2: I double checked in the sync app and it looks like users from mastodon show up as someone@instance.com/users/someone so it looks like it’s a UI specific thing

    It all just depends on whether it makes sense or not, and also whether the developers of each software coordinated to make it translate.

    Like you point out, text posts don’t exist on a video platform (at least if you’re not counting youtube community posts), so peertube devs didn’t write any code to receive or display them.

    How you get stuff to show up also depends on the platform, but I believe most will do it if you search the account handle of the account on the other service - so you can follow a peertube account from mastodon by searching @account@example.com and then it starts showing newly posted videos in your feed.

    Since all the translations are decided by the devs of each software, some of it is a little funky - like IIRC lemmy communities are displayed in Mastodon as an account that you can follow, and each post to the community is a post on that account (or maybe it’s boosted by that account, I can’t remember), so if you follow the “community account” from Mastodon, you will start seeing new posts in your Mastodon feed, and can reply to the comments by replying to the post. You can also post to the community from Mastodon by mentioning the community at the beginning of a Mastodon post, and I think it will boost it.

    It’s kinda weird IMO - I get the feeling a lot of posts from Mastodon in Lemmy communities might be made by accident because it often looks like the Mastodon user was just trying to tag an organization (like tagging @Plex or @Netflix to complain about their software or something) and then saw the account suggestion from Lemmy and didn’t realize they would be posting to a community instead of tagging an individual.





  • Ah gotcha, I see where the confusion came from then. I wasn’t considering the hypothetical scenario where he magically increases water pressure but instead thinking about what will happen in reality when the legislation allows people to get higher flow shower heads (and imagining some of them might be disappointed when it feels less forceful, though I’m sure plenty would enjoy an increased flow if that’s their preference). His talk about pressure is a stand in for the actual details of the EO which is actually about low flow fixtures (and I assume low gallon per flush toilets but I didn’t read that far).

    I admit I was thrown off trying to figure out what we were saying differently, I’m sure I could be more specific though about the hypothetical I was describing. I did a solid semester in multivariate calculus just solving flow equations so it would bring great dishonor to my teacher if I mixed anything up haha.


  • I appreciate the in-depth response but I think you are misunderstanding the point of my comment.

    My comment isn’t denying that increased pressure at the source can increase flow rate (note I say that you can’t increase pressure with a high flow shower head, I am not talking at all about changing the source pressure) - I’m just pointing out that people often conflate flow rate with pressure at the outlet, especially in domestic settings where the flow is intentionally restricted by design (like low-flow shower heads). In this case, pressure is maintained, but the flow rate is reduced by narrowing the outlet, which people mistakenly believe is a loss in pressure, while not realizing that they traded flow for that higher output velocity.

    When I say that “flow and pressure are inversely proportional,” I thought it was obvious that I was referring to how flow and pressure behave given a fixed source, since this entire conversation is about changing only the fixture. This is more about the relationship in practice when you change the outlet restriction. I’m talking about the “perceived drop in pressure” (what people mistakenly call pressure) when using a low-flow shower head, which is actually a result of lower water volume, not lower pressure per se. I’m definitely NOT talking about supply pressure and flow being inversely proportional, that’s obviously not true.

    So when Trump or others push for “high flow” heads thinking they’ll get “higher pressure,” they’re misunderstanding how their own plumbing works. High-flow fixtures let more water through, sure, but if your supply system can’t support that extra flow (especially with other fixtures in use), then the actual outlet force (again, what people call “pressure”) feels weaker, not stronger. That’s the irony I was trying to highlight.

    Your garden hose analogy is solid, and I think you’re mostly in agreement with my original point. You’ve just interpreted it as a misuse of Bernoulli, when I’m really commenting on how the misunderstanding comes from conflating pressure with flow, especially in domestic scenarios.

    To clarify:

    Increasing pressure, with no other changes, absolutely changes flow rate

    I don’t think I have disagreed with this - I mentioned replacing shower heads with higher flow shower heads, but of course that doesn’t change the supply pressure, instead the loss in restriction lowers the velocity coming out of the shower head

    Bernoulli’s principle that effectively states as flow increases, pressure decreases (and vice versa) when the source is not changed

    I believe I stated the same when I said that they are inversely proportional when you are only changing the outlet nozzle

    Since the bottleneck is more likely to be the miles of pipes and hundreds of bends, flow rate can’t really be inherently increased but pressure can

    Yes, this is what happens when you put a low flow fixture, you trade flow for outlet velocity

    The proper application of the principle is at the outlet with a steady source

    This is exactly and solely what I am talking about

    However, if you try to fill a bucket, you’ll likely find they fill at nearly the same rate

    This is about the only thing I disagree on - you can fill up a bucket on the shower setting much faster than you can on mist, this is the entire principle behind low flow fixtures. If adding restriction to an outflow didn’t reduce the flow then it would be pointless.

    In short I really think we are mostly in agreement, I think you are mistaking my comment as talking about the relationship between flow and source pressure, which is definitely not what I am talking about since changing your shower head obviously doesn’t change the characteristics of the water source. If there is something specific I said that doesn’t agree with what you said then please point it out, because it really feels like you are just repeating my intended message.



  • The dumb thing is that the EO is actually about flow rate, but lots of Americans probably don’t understand flow rate and believe that water saving shower heads cause lower pressure.

    What’s really ironic is that flow and pressure are inversely proportional, so using a high flow shower head as Trump prefers actually reduces the pressure (force) with which the water comes out.

    I had to try to explain this to a right winger expat in Ecuador who couldn’t understand why he couldn’t fix his dribbling shower when his wife was washing dishes by just slapping higher flow fixtures into them. I was unsuccessful.

    I’m pretty sure if you rip CDs directly to FLAC, it’s a perfect copy assuming you’re using good software. PCM isn’t lossy or lossless because it’s not a compressed format, it’s an uncompressed bitstream. Think of it like the original data. If it was burned to a CD as digital MP3 data and then ripped that to FLAC, then yes you’d be going from lossy compressed to lossless, which would hide the fact that quality was lost when it went to MP3 in the first place.

    Just as an example, you can rip a CD directly to FLAC (you should also find and use the correct sample offset for your CD drive), rip the cue sheet for track alignment, then burn the FLAC back to a new CD using the cuesheet (and the correct write offset configuration), and you’ll get a CD with the exact bit for bit pattern of “pits” burned into the data layer.

    You can then rip both CDs to a raw uncompressed wav file (wav is basically just a container for PCM data) and then you’ll be able to MD5sum both wav files and see that they are identical.

    This is how I test my FLAC rips to make sure I’m preserving everything. This is also how CD checksum databases (like CDDB) work - people across the globe can rip to wav or flac and because it’s the same master of the CD, they’ll get identical checksums, and even after converting the PCM/wav into a flac you are still able to checksum and verify it’s identical bit for bit.
