Again I don’t know what’s going on but picture wise we have several shapes, a light bulb, a torus, a lightbulb with a hole and thickened joined links all sort of pointed at one hole with open boundary

People who try to whitewash our country's history don't actually love America.

They're like a parent who only loves their kid when they win a trophy.

Real love acknowledges failures, mistakes, and growth. Real love is proud of a simple, honest desire to be better.

Chart showing maternal deaths per 100,000 live births have fallen by 57% since 1985. Progress was temporarily reversed during the COVID-19 pandemic, but rates have started to fall again since then.

As a result, there are around 365,000 fewer maternal deaths each year than in 1985.

I'm sure it is a concept widely familiar to the Ruby community that:

If it walks like a duck

and it talks like a duck

then it's clearly a neo-nazi for all intents and purposes.

Reposting this in a more constructive matter to simply point out that people who have vocally expressed clear white supremacist, transphobic, sexist, racist, and generally nazistic views, such as David Heinemeier Hansson, are not and never will be internally consistent and operate on cowardice.

Wait, did Rust developer count really double in the last year? If so, that's incredible. Only three more years to pass JavaScript at that rate!

I'd one hell of a lot rather be on the autism spectrum (and I am, tbh) than the RFK spectrum. Whatever the hell spectrum that is. The fascist chip-on-the-shoulder-that-blocks-out-the-sun spectrum?

Because a hell of a lot of Rustaceans have UB PTSD from years in the C++ trenches and are easily triggered.

I Thought I Knew Silicon Valley. I Was Wrong Tech got what it wanted by electing Trump. A year later, it looks more like a suicide pact.

When @wired asked me to look at Silicon Valley in the age of Trump, I saw the crash of the idealism that originally drew founders--and me--to the tech revolution. Selling out the dream will not serve those moguls (or us) well. www.wired.com/story/silico...

I have a worse Rust book. Was gifted it based on the title -- thoughtful gift, but the book itself is wall to wall AI slop. This is one case where you absolutely can tell the book by its cover.

This is because testing is not a thing. Since you cannot test for fun, all other testing is therefore also bad and wrong

Just 6 years ago anti-vaxxers were a laughable fringe group. Now their victory is so total they're setting government policy. This is like if schools started teaching Flat Earth. A complete failure of education and science comms. Kids will die because we couldn't convince their parents of the truth.

I've found that a certain kind of person finds comfort in ignorance, because knowledge carries with it work and responsibility. It takes work to acquire it, and once you do you must either act on the knowledge or accept that you refuse to do so, all of which is hard and painful.
