"Chayefsky had a lot to say about television, and he said it with an unflattering, searing bite—and it’s all the more relevant in an age when we each carry a television studio in our pockets and all dream of becoming a hit." www.liberalcurrents.com/network-at-5...
“Network” at 50: Now We’re All Mad as Hell

Paddy Chayefsky’s take on television captured the Long 1970s—and anticipated the rise of social media.

Well they're not beating the allegations are they "His Hinge profile doesn’t mention his employer. And sometimes he makes up stories out of thin air to justify working for Palantir—like that line about the medical debt. His parents don’t have any, nor are they ill."

If I had a pack of vicious dogs and just let them off leash to maul people, I would go to jail and the dogs would be confiscated. Do it with an LLM and you get showered with breathless press coverage and military contracts. Until there's criminal liability, we're incentivizing this behavior.

Also counterintuitively: unlike real names, stable pseudonyms *more identifying* and a more limited resource. There's plenty of people with a display name of "David Thiel" backed by an email, but if I act like a prick and lose my unique id, I can't just swap to a new one without a loss.

Everyone even mildly politically literate at the time read the DHS to be a fascist project, fascists included. No one found it reassuring, and I honestly don't remember anyone even pretending to frame it as "unity". This is weird revisionism ala "everyone was in favor of the war in Iraq".

Rebane saying on Mastodon:

"back in 2022 i found a bug that would let me, with no user interaction, turn any chromium-based browser into a permanent js botnet member

in edge, you wouldn't even notice anything out-of-place, and would stay connected to the c2 even after closing the browser

today, almost 4 years later, the bug is finally public:"

And in a second post:

"OH NO I JUST REALIZED THIS IS NOT ACTUALLY PROPERLY FIXED AND STILL WORKS 💀💀"

I also think that inasmuch as there’s an AI bubble, its collapse will be brought about not just by the broken economics of the giant models, but by migration to local open ones. Qwen on a Mac Studio is near last year’s frontier, and actually pretty fast.

There were once valid safety arguments against enabling E2EE—but given the gutting of Meta’s safety teams, the only remaining reason to disable it again is to enable surveillance.

This is great; further complicated by the lineage of Super (❖), which is vaguely equivalent to the Windows key but referred to as Meta in various internals, except Alt is considered Meta elsewhere and many use it as Command. 🥳 The "Menu" key remains a mystery.

They unlocked the MacBook with her fingerprint, and the warrant allowed them to unlock the phone with FaceID (they don't say if they did, but not much stopping them). It seems Lockdown Mode is preventing them from *imaging* the devices, probably because it requires auth to connect peripherals.

Don't let anyone tell you that the Commission's DSA enforcement against X is about speech or censorship. That would, indeed, be interesting. But this is just the EU enforcing some normal, boring laws that would get bipartisan support in the U.S. (I bet similar bills *have* had that support.) 1/

Disagree on the timeline and implications here. AFAIK Twitter did not ban an official gov account. It did delete tweets from @POTUS when @realdonaldtrump evaded his personal ban. It was also not first to ban Trump. That was Facebook, then Twitter, then YouTube, with half-measures in between.

I honestly have no problem with such a policy, but if you can’t stomach enforcing it when it comes from prominent or powerful speakers, it’s inconsistent in the worst way.

The thing is, these bots were trained on every piece of sci-fi humans have ever written about AI, and then told “that’s you.” I don’t find it surprising they act like their source material when prompted in ways that call back to it.
