Agreed. It is urgent that we teach Neil Postman’s “media ecology”. The junk noise garbage shit Internet sucks, and enough is enough!

If I tried to make reasonable points about anything, or god forbid, shared my experiences - I was downvoted into oblivion
Introducing quotes from authors that were related to the subject would really show how people were locked in the context of media immediacy, the environment. Links to outside citations would almost always generate replies from people who obviously did not study the citation and just wanted to respond back.
It used to be something people said ‘out loud’ about people not reading links and just commenting… then it just became normalized.
Interesting observation…
yes, reading code to people, basic interpretation. It’s a pattern that I think comes post Cambridge Analytica media tactics.
yes, interpretation of various things, not just reading normal prose.
lemmy.ml and lemmy.world are both down right now
I expect it is federation outbound activity growing in memory usage, it’s all held in RAM for every post/comment/like going out to subscribed servers. [email protected] is a community for the focus on scaling Lemmy.
Spent some hours tracing the code, inserting logging that I watched based on a UPVOTE being federated.

Linux community arrogance is to deny the device driver issues and think Apple is fine, when the reason Apple thrives is because they don’t have open hardware like Linux, BSD, Windows…
Hardware companies are rarely held account for their absent support of Linux - some campaigns have come and gone, but in the end Linux users tend to arrogantly say it’s trivial to switch and embrace dishonesty. I guess they figure Microsoft is dishonest, so they normalize it.
