Without naming your job, tell me something you say over and over again at work. "Hold on. What's the threat we're trying to defend against here? And why will this help?"

The recent days have been horrific. We can't become numb to repeated instances of illegal and unconstitutional action by government agencies. It's even worse when public officials are blatantly lying in ways that contradict dozens of pieces of video evidence.

Discovered today that "colorable" is a contranym -- it can take one of two opposite meanings, either "seemingly valid" or "intended to deceive".

Holy fuck. Any company that thinks they're going to avoid the need to fight -- or to utterly debase themselves -- is not dealing with reality.

You set the house on fire, watched it burn, and then lost your nerve and put it out. You now have a partially burned house. Great job.

President Dwayne Elizondo Mountain Dew Herbert Camacho *cared* that his country was suffering. He eagerly sought intelligent advice and let it change his mind. He was held to account by a vigorous legislature. For us, today, Idiocracy might as well be The West Wing.

It really is such masculine energy to blame things on a woman who no longer works at the company www.nytimes.com/2025/01/16/u...
Mr. Zuckerberg was amenable. He signaled to Mr. Miller and his colleagues, including other senior Trump advisers, that he would do nothing to obstruct the Trump agenda, according to three people with knowledge of the meeting, who asked for anonymity to discuss a private conversation. Mr. Zuckerberg said he would instead focus solely on building tech products.

Mr. Zuckerberg blamed his former chief operating officer, Sheryl Sandberg, for Facebook’s culture, according to one of the people with knowledge of the meeting. He said new guidelines and a series of layoffs amounted to a reset and that more changes were coming.
