It expects the communities to be on the post instance or your instance (lemmy.world) if not specified. The community should always be referred to as [email protected], which automatically works as a link.
There are a lot of different apps / frontends that can show stuff from Lemmy, and they vary in how well they support different link formats. Here is a short explainer:
Each entry below shows you what you should type (like this) and what you will see as a result (after the dash '-').
For each entry, some apps will support it and others will not. It can be helpful to include a few different link formats so that everyone can use the link easily.
NOTE: There is a bug on the Lemmy website right now. If you start typing a community or username, it will try to autocomplete it. DO NOT click that autocomplete, or it will mess up the link.
This is another way to make a universal link. If you click this link, the community will open in your home instance.
This works well if you can't use the method above. For example, if you want to stick a link in a shields.io badge, you can use this technique to still include a universal link.
This is a hardcoded link. If you click this link, the community will open on a specific instance. Anyone using a different instance (ex. anything except lemmy.ca in this case) will not be able to subscribe right away, and they will need to redirect it first.
Sometimes you can't use the methods above. For example, if you want to create a nice thumbnail while promoting your community on [email protected], you will need to use this URL.
If you use this method, try to use the other methods as well so people have options.
Hi there! Looks like you linked to a Lemmy community using a URL instead of its name, which doesn't work well for people on different instances. Try fixing it like this: [email protected]
I used to like Kurz back when he was discussing things I had no knowledge of, but the moment they entered an area where I was experienced in it became clear that it's primarily on the entertainment side of edutainment.
Nothing they say is explicitly incorrect, just vague and missing critical context.
For example, a video about the potential for a space elevator spoke of an alternative that would require aircraft to be "caught" by an orbital trebuchet style system. The reason the alternative was even conceived was because we don't have the material for a space elevator given our planet's high gravity well. During the discussion Kurz let it slip that the system would require an aircraft to fly at MACH 12!
If materials science has developed the technology for an aircraft that could fly that quick with atmospheric friction... We'd just be able to make a space elevator anyways.
I want to like them but I don't find them trustworthy after watching their climate change optimism video and a takedown that explains how ridiculous it is.
The video title is very misleading, current video “How to win interstellar war” has actual no real science behind it. We can not predict a war, no one has. Another thing, we haven’t even proven if aliens are real. kurzgesagt just made it up.
