Yes and no. Pi is assumed to be normal, which means that any non-infinite sequence happens in pi. However, the digits of 0.1011011101111011111... are infinite and non-repeating, and yet you'll never see a 00 or a 2.
Yeah I agree, I just don't call "stuff's gonna be bad" doomerism (it's pretty clear at this point). I call "this is the end and there's nothing we can do" doomerism.
There's a pretty big difference between "it's going to get a lot worse before it gets better", and "it's already over, we're all fucked".
The original comment presents things poorly: we are past several "points of no return", but saying the point of no return implies there's nothing to be done.
Additionally the last point is... pretty much entirely wrong. We have absolutely made significant and noticeable progress against climate change. It's not enough yet, but it's absolutely not nothing.
The point you're missing is that it isn't about integrating significantly different platforms like lemmy and mastodon, but rather connecting platforms that are close enough.
Mastodon federates with misskey, firefish, iceshrimp, sharkey, (all extremely featured and very similar to mastodon), writefreely (more for blogging and writing but absolutely connects), some wordpress websites (there's a plugin), peertube (you can follow channels to see when videos are posted), friendica and who knows how many tiny custom instances.
This allows massive customisation of your experience.
Anyway, interop is more of a happy side-effect of using a common federation protocol
It works, not seamlessly but close. Any community is considered to be an account, with any posts made to it considered to be a "tweet". Any comments are replies to the post. A microblog account can post to a community by @ ing it, and reply to comments and posts by... replying to the post.
From lemmy to microfedi doesn't work as well, but you can reply to posts as normal and like by upvoting.
Yes and yes. The folder is just a bunch of markdown documents, as well as a hidden folder containing configuration, plugins, etc (json, js, css, etc). The vault is entirely self-contained.
On the second point, Obsidian's vaults are intentionally stored as a single folder that can be synced easily, including all settings. They do have a service for syncing, but with a bit of tech know-how it's still really easy to sync. Also, all notes are stored as plaintext markdown files, which is convenient since many programs can read markdown.
This one's pretty good!
