I'm still getting the hang of Lemmy and federated services.

I'm browsing the programming.dev instandce in the Liftoff app and I can choose to view:

1. my subscribed communities on the server (currently none)
2. Local communities on the server
3. All (?)

I know All is not "all communities on Lemmy" but what perplexes me is I can see posts from another community that is hosted on a different server and it appears because it is "via programming.dev".

At first I thought it was because a user registered on " programming.dev " posted on another instance but I opened my eyes and saw the user's origin is no way related.

Any ideas?

EDIT:

After reading all the comments I’m pretty sure “via programming.dev” should read in the context of the post as !community@instance is known via programming.dev instance. I guess it makes it explicit which “all” I am browsing if I pick up browsing where I left off and forget I am not in the “all local”.

At this point I have only seen this on the Liftoff App for Lemmy but still trying other. Must be in the metadata and Liftoff decided to display it.

I created a Lemmy instance. Making posts, comments, all that jazz seems to be good. Sign up works. Other functions work. What doesn't work is federation. The instance is been alive about about 24hours and I don't see anything in the all tab. Directly going to communities via a url like "my.lemmy.instance/c/sub@other.instance" shows the external community's sidebar, bur not the posts I know exist.

I haven't added anything to the allow or block list and federation is turned on. Have I missed something or is it just a matter of waiting a little more?

Because I'm in my very early 20s I missed out on the huge Java craze. Everything was Python when I started getting a more formal education and before then all my work was in C++. Knowing more languages would obviously look better on a CV but I mean if I would benefit in a practical sense? I have two friends who are long time Java devs. And recently another friend who generally works with legacy C++ based systems from the early 2000s late 90s period had to work on a bunch of stuff in Java. Java is clearly still in large scale use among older systems. So would it be likely that eventually I would need to work on Java systems myself when my job is mostly JavaScript currently?

Hello, I currently have just a little experience with asp.net and rest api's, but most of my development is windows desktop apps. I'd like to learn a javascript framework (angular, react, vue, or next.js are some I've looked at) and I was wondering if anyone knows of a good tutorial for using one.

#1 - Is there a general search function, not just for communities.

#2 - Is there a subscriptions view

This is a place where you can ask any programming related questions you want!
