The Anxiety of Learning
Everyone touts learning organizations, but few actually exist. World-renowned psychologist Edgar H. Schein draws on decades of pioneering research to explain why.

I love watching the corrupt Democratic Party establishment, along with their paymasters and enablers in the media, running around absolutely peeing their pants at the thought of Mamdani becoming Mayor of NYC. I cannot wait for him to win.

Andrew Cuomo is expected to announce this week that he is staying in the New York mayoral race as an independent, despite the latest polls showing his odds of winning are slim.

The corps like Publix that get mad about CIW & fair farm wages, it's not bc proper farm wages will put them out of business.
It's because they get upset when ANY workers get collective bargaining wins. It's just generic anti-labor politics- not an existential threat to their business.

Ex-farm worker here.
We need to talk about this whole "But a living wage for farm workers would spike the cost of food!" thing.
Not true AT ALL.
Y'all don't understand how fast experienced farm workers are.
The average tomato picker pulls 650lbs per hour.
At $20/hr, that's $0.03/lb for labor.

When the first family separations of migrants happened under Pres. 45, one of the talking points was that it was being done to stop people trafficking. In fact, as this Pulitzer Prize winning investigation shows, it was done out of pure cruelty as a “deterrent” www.theatlantic.com/magazine/arc...

Catastrophic that after many months of funding and arming a genocide, the USA is now directly bombing Iran. All because 45 tore up the JCPOA agreement out of spite and hubris. The obstacle to peace in the Levant is the _actually_ nuclear-armed and genocidal Israeli state and its partner the USA.

From a CD point of view, you can think of an AI agent as an ephemeral junior developer. So all the stuff you needed before like a CD pipeline, good test coverage, small changes etc, you still need now, but even more so because per this IBM slide from 1979, a computer can never be held accountable.
