The CDC has updated its vaccine safety page to promote long-discredited claims about vaccines—namely that they cause autism.

The page links to a number of studies, including one by anti-vax allies of Robert Kennedy Jr.

I do understand: you want permission. There’s a machine in the corner wrapped in human skin that makes things out of shit and blood to look like whatever you want (as long as you don’t look too closely). You gave one to your teacher and they didn’t notice. Your boss told you to use it after they laid off half the team and it was fine. You fed one to your kids and they liked it. You want to know you can use it sometimes without me thinking less of you. You don’t need me to believe it’s useful, you just want me to be polite about it. But I am a hater, and I will not be polite. The machine is disgusting and we should break it. The people who build it are vapid shit-eating cannibals glorifying ignorance. I strongly feel that this is an insult to life itself.

Absolutely worth a read. Taking a shot at defining what makes a game AAA or Indie (without calling it 'indie') by using actual data.
The install footprint + length of credits seems to be as good a metric as any.

The first big move in that direction is an experimental feature called “Agent Workspace,” which gives AI agents access to the most-used folders in your directory, such as Desktop, Music, Pictures, and Videos.

This year we have sold 31% of the advent calendars that we sold last year 😓

The art is so pretty and colorful 🥺
The facts are so good 🥺
Eels are so cool 🥺

Get an eel facts advent calendar at EelFacts.net
Sarah holds up an eel facts advent calendar in front of blooming flowers on her sidewalk. It says eel facts an advent calendar. It has 24 boxes with orange and yellow zigzags and yellow circles in the middle with numbers one through 24 in the middle of the boxes there are six eels depicted on this calendar, one green Moray, two splendid garden eels, one blue and yellow ribbon eel, and one American eel and one European.

Misinformation *is* central to democratic problems today, but the solution is *not* to correct such epistemic failures directly. Instead, we must address them at their roots, in social identity.

Or so I argue in a new post for @apaphilosophy.bsky.social.
