kind of amazing that everything trump does can be understood through the lens of narcissism and it's related needs (e.g., self aggrandizement, revenge, domination, grievance validation). i don't think any character has been so one-dimensional, not even wile e coyote or scrooge mcduck

Turn Dependabot Off I recommend turning Dependabot off and replacing it with a pair of scheduled GitHub Actions, one running govulncheck, and the other running CI against the latest version of your dependencies.

Dependabot security alerts have terrible signal-to-noise ratio, especially for Go vulns. That hurts security!

Just turn it off and set up a pair of scheduled GitHub Actions, one running govulncheck and the other running CI with the latest version of your deps.

Less work, less risk, better results!

If the right dominates the infosphere, if they can demonize any marginalized population they turn their eye on, then strategizing around *a current snapshot of public opinion* is almost definitionally misguided. They can change that opinion. Dems can't seem to, or won't try. All else is noise.

You can place pancakes, crepes, and scrambled eggs on a simplex where the variables are the ratios between milk, eggs, and flour, (with another small axis for baking soda.)

We have explored too little of this manifold. More breakfasts can exist than we have known.

How is it possible that Kristi Noem still has this job. Imagine if you’re a family member or a shipmate of this guardsman.

Elon Musk posted about race almost every day in January Many social media posts by Tesla CEO on his platform are indiscernible from those of white supremacists, say experts

Trump wasn’t a glitch in American politics. He’s a symptom, not the disease.

He figured out that there’s about a 40% base of voters that supports white supremacy, add anti-LGBT backlash + tax cuts and you’re near 50%.

The masks are off. They’re not going back on.

Last night I could not sleep so I created a taxonomy of people who work on inequality/redistribution. For each of these groups I have names of economists but it could be too controversial. So I decided to stay with the taxonomy only. (You can fill in the names.)

How can you change the public vibe about immigration? Well, that's a good question, worthy of discussion. One thing is clear, though: *changing the reality of immigration policy won't do it, because it isn't meaningfully connected to the reality of immigration policy*.

I bet if you just did a simple survey, not one American in 10K would be able to accurately tell you the current level of immigration to the US, whether that level is up or down from the previous decade, what countries are most represented among immigrants, or what current US immigration policy is.

"Moderna's CEO announced the company will no longer invest in new Phase 3 vaccine trials for infectious diseases: 'You cannot make a return on investment if you don't have access to the U.S. market.

In terms of what cures are being lost:

- Epstein-Barr virus is perhaps the major trigger for multiple sclerosis
