On a vaguely similar note, it might be cool if using the crosspost feature pooled upvotes from the various crossposts, and only let one of the crossposts show up in anyone's All feed at a given time. It would make having multiple splintered communities for one topic less annoying, encourage cross-posting, and reduce spam when someone crossposts something to 5 communities and all 5 show up on your All page.
To really work I think it would have to pool comments together too - but then you run into issues with moderation. I'm not sure if there's a good way to fix that issue.
Not really related to your post, just me being nosey: When I go to your account page, your most recent comment was "[ Removed by Reddit ]". What had you posted?
Spinning it at 1575.42 Million RPS would create a 1575.42 MHz radio wave. That specific frequency is used by the GPS - so by doing this you'd be interfering with the reception of GPS signals, which is the illegal act you'd go to jail for here.
I was maybe a bit sloppy when I said it "quickly drops to 0" instead of it "quickly tends to 0". It'll of course always be positive - in fact if N is the sum of the absolute value of the three coordinates of its current position, the probability of returning to the origin is strictly greater than 1/6ᴺ.
But it does tend to 0 in such a way that the probability of its random walk ever returning to the starting position is not 100%. It has a 34% chance of ever getting back at the very start of its journey - but if it gets too far off track that probability is going to tend to 0 fast enough that it's not likely to ever make it back, even with infinitely many steps. Here's a youtube video (that I did not watch myself) that seems to go over the topic.
If you limit the extent of the third dimension to any finite value then my intuition says the probability is probably back to 100% but I don't know for certain.
In this context, a random walk happens on a 2D coordinate plane. Your drunk person starts at the origin, (0, 0), and for a "random walk" they move either left, right, up, or down by exactly 1 unit each step. It's a mathematical fact that this process, taken to its limit where infinitely many random steps are taken, will always have the drunk return to the origin - in fact, for any given integer coordinate on the plane there's a 100% chance the drunk will eventually visit that coordinate following a random walk.
This doesn't work in 3D though, where there's an x, y, and z axis. A random walk there won't always return to the origin - it only will about 34% of the time. If the drunk gets too far away the probability of ever finding their way back at random quickly drops to 0.
On your homepage, you have some options at the top for what to display.
The first option is Subscribed/Local/All. The default is Local - change it to either Subscribed (If you like subscribing to communities) or All (If you prefer to just see everything). Keeping it on "Local" is a pretty poor way to use Lemmy - it'll only show you posts from lemmy.world and never from any of the other Lemmy instances. This goes for when you're searching for communities too - make sure you set the search to "All" and not "Local".
The second option is how to sort - with the default being "Active". "Active" is a bit too slow to update for most people's taste - you might find you like "Hot" a lot more. You can set the default for both of these options to whatever you want on your settings page.
When browsing, if you find a certain community (subreddit) consistently puts posts in your feed that you don't like, there's a handy button to block that community if you go to it, in the top right.
Past that, just do your best to be active - more active than you may have been on reddit, because Lemmy is a lot smaller. Upvote posts you like, comment on posts where you have something to add, and post things you find elsewhere.
I was skeptical of this, but it checks out: I easily got ChatGPT to print out the full text to The Tell-Tale Heart, without any errors at all in the various spots I accuracy-checked.
Granted I chose it because it's a very short public domain work - I was more skeptical of its technical ability to recall the exact text without errors than of the ability to trick it into violating copyright law.
I still suspect it's much easier to (accidentally) trick it into writing a fanfiction of a copyrighted work that it claims is the original than it is to get it to produce the true original, though.
You can but they want to see the "Local" view from the perspective of other instances. If you go to your homepage a click the "Local" button at the top you see only posts from sh.itjust.works communities. OP is on lemmy.world so they see just lemmy.world communities if they select that option. They want to see this page from the perspective of any instance they want.
Could be useful particularly for instances that are topic-specific, instead of general purpose.
This is a really long video - but I found it very worth the watch. Ceave has almost nothing but good takes - and it's a fun retrospective for people who played the game years ago, while giving a lot of interesting information on the history and lore of the game. His insights into game design, mechanics, and development border on psychic at times - the guy has a gift.
My understanding is similar. From what I gather, the theoretical understanding of why superconductivity happens is weak at best - so most (all?) superconductors are found by brute force, accident, or modifications to existing superconductors.
It'll be an interesting middle-ground if this is shown to be superconducting in some configurations, but if it ends up not being reliable to manufacture on industrial scales. If it is confirmed, though, I expect ridiculous amounts of money would be thrown at the problem...
Just doing a quick search of the Beehaw communities I'm subscribed to (I have hope...), I found this post from 3 hours ago and this post from 2 days ago - note that both were made by lemmy.world members, and you can even see some comments on the second one from lemmy.world users too. I'm guessing this is the sort of thing you saw, going by the last point @CMahaff mentioned in their reply.
It was a bit inaccurate: On other instances that are federated with both us and Beehaw, we can interact with Beehaw users and they can interact with us. That's because in that case it's the third instance handling the federation - they send the information to both us and Beehaw. All Beehaw's defederation does is stop receiving information from lemmy.world directly, and stop sending information about itself to lemmy.world.
