One symptom of being dumb is that you're unable to see the world with any nuance; Just "owned" and "based".
Rampant and proud anti-intellectualism is the result of these same people realizing that being dumb is being "owned", then collectively coping that it's actually "based".

Web Components Are the Comeback Nobody Saw Coming
Web components enable UI interoperability, allowing you to build reusable components that work across any framework — or to avoid frameworks altogether.

It’s the “season of love and giving”…but this year, doesn’t it seem more like a “season of fear and taking”? Like many of you, I’ve been saddened by the human impact of draconian government budget cuts and how angry many housed Americans are at unhoused Americans.

I say this with zero irony: if you are even tangentially a part of a retro video game community, it is your civic duty to push back against this company and shun anyone who doesn't. This is fascism tapping gently at the door and as soon as you let it in, it's going to invite its friends.

Good thread from a good person in a tough situation ❤️ I’ll keep using and believing in Firefox as long as they employ folks like this.
Something that hasn't been made clear: Firefox will have an option to completely disable all AI features.
We've been calling it the AI kill switch internally. I'm sure it'll ship with a less murderous name, but that's how seriously and absolutely we're taking this.

An enjoyable look at how LLMs work under the hood from @samwho.dev. The whole chain of tokenizers (text chunks), embeddings (vectorized text chunks), transformers (the "T" in ChatGPT), caching (reused chunks), and all the math that goes into returning a response.
