It’s a terrible time to be someone who pays attention or cares about other people.

Hundreds of Alligator Alcatraz detainees drop off the grid after leaving site As of the end of August, the whereabouts of two-thirds of more than 1,800 men detained at Alligator Alcatraz during the month of July could not be determined by the Miami Herald.

More than 1800 detainees are missing after the closure of Alligator Alcatraz. Their families and lawyers can’t find them and they’ve vanished from the ICE database. Feels like this should be a much bigger story www.miamiherald.com/news/local/i...

America is telling many of its most talented workers that they are no longer needed.

Highly talented queer, transgender, women, and black workers have been hit the worst by layoffs and what CEOs are describing as a class of permanently unemployed as the USA focuses on "ending DEI".

There is no universe in which this is defensible.

Way back when we released the APT1 report, a Taiwanese news company (maybe Next Animation Studio?) released a hilarious animated video news clip about it.... Anybody happen to have a copy of the video or know where it still lives online? It seems to have fallen out of search results... 😁

As someone who entered the job market right around the dot com bubble bursting, I believe the correct question is "Do you think every major CEO could be wrong *for a third time in my lifetime*?"

Free markets are excellent, except when applied to ideas or opinions. Then they’re bad.

i am simply asking the press to cover the government sending masked thugs to rip people from their crying children and shipping them to a foreign concentration camp with the same ferocity they cover a trans kid playing jv tennis in sheboygan

Washington foresaw this day coming...

"They serve to organize faction; to give it an artificial and extraordinary force; to put in the place of the delegated will of the nation the will of a party, often a small [...] minority"

This shouldn’t be controversial but I’m against a police state abducting and deporting men they claim are bad dudes not because I can find a few I don’t know much about who I can claim are actually good dudes. I don’t care what kind of dude. My problem is with police state abductions.

Senator, welcome to Bluesky.

Can you explain why you're sponsoring a bill to repeal Section 230, which would effectively make it impossible for Bluesky to do what it's doing today, creating this kind of space?

Thanks.

Medicaid is not for sale.
NASA is not for sale.
The Post Office is not for sale.
America is not for sale.

We have an obligation to resist kings. We outnumber them. And they can be overwhelmed.

Lots of questions about the new admin protection feature in Windows so the MORSE team decided to do a writeup. Working on part 2 now, should be done in a day or two. techcommunity.microsoft.com/blog/microso...

A Chinese national, charged with fraud by the SEC, just sent Donald Trump $18 million Chinese Crypto entrepreneur Justin Sun paid $6.2 million for a banana β€” sold by Sotheby's as conceptual art β€” and then ate it last Friday.

Call me crazy, but I think Justin Sun, a Chinese national being prosecuted for fraud by the SEC, sending Trump $18 million should be a bigger story

The direct enrichment of Trump by a foreign national weeks before he takes office has merited no coverage in the NYT or Washington Post
