The short answer is no but the longer answer for what happens in each situation was detailed here: https://codeberg.org/Kbin/kbin-core/issues/1051

lemmy -> kbin = pretends to send but doesn't

One thing to keep in mind is they don't federate with kbin.social; so they can't see your posts or replies, and can't reply to you. I believe your upvotes won't federate (maybe to other instances, but not to theirs at least). Downvotes work the same as they do for any other post as those don't federate in kbin to begin with. One-sided federation in the fediverse seems like it can be a bit confusing to users, I'm not sure in what case it's a good idea in since it can be like talking to a void.

This goes up to 120 days:

This seems to be a popular topic today, I imagine it must be getting worse for kbin.social users (the errors when posting threads / images, if it is that)

I made this issue for what you described https://codeberg.org/Kbin/kbin-core/issues/1019

@ernest sorry to ping you but just want to make sure you're aware of this as the last ~4+ posts to this magazine have been about this issue

You might've already seen this, but just in case other people missed it since not everyone may follow ernest or check the microblog tab, he listed his current priorities here https://kbin.social/m/kbinMeta/p/1002621/Hi-in-this-and-probably-the-next-week-I-will so hopefully people won't have to deal with this too much longer 🤞

It's a shorter url for local links, but it's also the actual location of the source of the content.

So for this thread, copy url for me is https://fedia.io/m/kbinMeta@kbin.social/t/134107/What-does-Copy-URL-to-Fediverse-do
however, copy url to fediverse is https://kbin.social/m/kbinMeta/t/240118

The latter is the url that can be used to load the content on other fediverse platforms. For instance, if I take that url and plug it into the search, it will display the thread: https://fedia.io/search?q=https%3A%2F%2Fkbin.social%2Fm%2FkbinMeta%2Ft%2F240118 (edit: this might be a bit iffy. it showed the top thread post before but now it shows a comment inside the thread. I think it's a bit wonky at the moment some times)

I think a shorter answer is: the first url is the location on your instance, the second url is the location of the original content

This is true for profiles, comments, and threads. For instance, I see a lemmy.ca user commented on this thread. Their comment's url to fediverse is actually https://lemmy.ca/comment/1519825 because they are posting on their instance's copy of this thread, so the source of the post is a different server

Edit: This is a little mastodon specific but goes over the concept, especially the last two sections https://fedi.tips/what-are-original-pages-in-mastodon/

There's a page to see only entries from subscribed magazines: https://kbin.social/sub you can get to it by the hamburger on the top bar
And a page to see the magazines you subscribe to: https://kbin.social/settings/subscriptions/magazines which appears in user settings

Do you mean something else by list of subscribed magazines?

On the sidebar, if you click the fediverse icon (the 3 dots with lines between them), you can turn federation off. This will show you only local content. However, this does still show local kbin users posting to federated magazines, because technically they're posting to the local copy on kbin and it just happens to get federated out on the backend. But it should reduce the amount of completely federated things you see

A delete event is sent out by the server and attempts to be federated to all subscribers [source]. However, there are some caveats. If the destination is down or other issues in federation occur, although there may be retries depending on implementation, eventually it may give up and not federate the delete. Furthermore, activitypub is an open protocol. People can simply implement their own service that subscribes to things and drops all delete events.

Firefox runs really poorly for twitch and youtube videos for me in linux; mainly in CPU. Brave will use maybe 10-20% of my cpu for a single twitch stream whereas firefox uses about 80%. I use firefox for all my browsing, but for videos it just doesn't seem to work well... Perhaps a different chromium browser would be better as you say.

I attended a talk in 2019 by Sir Tim Berners-Lee on Solid, which sort of seems related to what you are getting at. The idea being that you own your data/identity, and can decide to share it with third parties. It goes over things like files, but I believe login identities were also meant to be part of it, I see when I scroll down:

authenticated by a decentralized extension of OpenID Connect

I've been wondering recently, especially with Pixelfed adding login with Mastodon recently, if anyone has heard or experienced anything with that project. But considering I haven't seen it spoken about or implemented since then, I'm not sure I should be hopeful

Just a note that the original team moved to PrivacyGuides. I didn't do much reading into the entire ordeal as it seems like a sort of each side has a story ( here's privacyguides ), but you can see on the site you linked it seems to be a bunch of ads and crypto now.
