I’m a professional software developer with 30+ years of experience. I prefer writing backend applications.

My phone is always silenced because I’m not an animal.

Sharp and provocative prediction by @gruber that ICE raids will focus on blue cities, allowing red zones to continue hiring and relying upon undocumented workers as usual. This would provide the spectacle of retributive suffering that invigorates Trump’s fans, while containing the economic consequences of mass deportations to Trump’s domestic opponents. https://daringfireball.net/2025/01/ice_raids_are_an_escalation_of_a_de_facto_cold_civil_war #uspol
ICE Raids Are an Escalation of Our Long-Simmering De Facto Cold Civil War

Trump says they’re targeting all undocumented immigrants, but so far they’re only targeting those who live in places that are popularly opposed to it. And that’s where the costs — both emotional and economic — will be felt.

Elon Musk's salute is a standard-issue far-right trolling tactic. I call it fascist peekaboo, and explain how it works here.

But it's not working so well this time. I explain how progressives and the press are getting smarter on how to respond.

Don’t CW this. I beg you.

My wife is on Instagram. She just did this.
She heard there was weird stuff happening. She searched “#Republican” and “#Democrat”.

She had to do it herself to see if it was true.

It is.

She is beside herself.

This is the 2025 version of marching into CNN and telling them to broadcast only his stuff.

This is him taking over the NYT.

This is new age Oligarchy. This is Authoritarianism. This is Fascism2025.

Edit 6:27AM Jan 21: BBC article confirmation of problem https://www.bbc.com/news/articles/c4g32yxpdz0o

Instagram hides search results for 'Democrats'

Meta says it is working quickly to resolve the problem, which has prompted accusations of bias on social media.

Every time I drive thru the PA countryside, I get more disturbed: more Trump signs are up each time. This time: 3 businesses had replaced their "Joe's Shop" street sign with "TRUMP" thirty feet in the air. One had a big camo military truck festooned with flags under it.

Fuck you, fascist cowards.

This and jobs. I just had a long debate with a friend who has set up shop in Texas and was talking about how he can’t get qualified candidates to apply for his team. My argument was “more than 50% of the population can’t realistically move there because they are being denied basic human rights.”

Political parties aside, it’s not a move my wife and I would consider for any amount of money. What would I say? “Alright family, I know 2 of you might die from this move but I think it’s really the right financial play.”

Trying to imagine being a few months pregnant and being told I have to go to a conference in a state where they have let women die if they have a complication that may become fatal.
