Y'all need to stop beating up the number 4. It's not a bad number. In fact, almost everyone's favorite number is less than 100, which given the infinite number of numbers is an astronomically high signal that the best numbers are in fact between 0 and 100. 4 could well be the best number.

Troy Jackson: "The gentleman's name was Johan Sebastian Guerrero. He had a 3 year old daughter. The only mistake he made that morning was going to work. Because Sen. Collins is not willing to stand up to Donald Trump, he was murdered in the streets of Biddeford for doing nothing wrong."

Cat is 100% right about this. Obstacles, strife, friction -- these are REQUIRED ingredients for being human. Our capacity to feel good tracks with our capacity to feel bad, because really it's the capacity to FEEL. If AI makes everything convenient, humanity devolves to isolated socialslop.

"The older I get, the less I care what other people think." Is it weird that I experience the opposite? The older I get, the more I care what other people think. If I could, I would anchor my time around learning about other people, their experiences, what they think.

When we took office, NYC had a $12B deficit. Today it’s zero. And we didn’t close that gap on the backs of working people. We closed it while funding parks, libraries, safer streets, & public housing. Call it Pothole Politics or Democratic Socialism: We are government that delivers for the people.

We all know that marriage is for mortals, right? It only makes sense if you expect to die at some point. That's not a criticism of anyone, it's just a practicality.

Little-known fact: 16,750 years ago, cracks in the bottom of the retreating glaciers funneled small rocks into straight lines all over New England. Many ancient people used these rows of rocks as property lines.

sure genAI can help write the thing, but does it feel any satisfaction in expressing itself? the optimistic thrill that someone might read it? the satisfaction of crossing it off a to-do list?

"internal family systems" therapy is no joke, and if you pick up a book on it and go through some exercises without a trained therapist to guide you, it can seriously fuck you up. don't ask any of my parts how they know. they are all busy screaming.

It remains a great modern tragedy that a revolutionary and cheap gene editing tech w/ obv applications in medicine and ag was discovered w/ public grants at public universities 13 years ago, and they've been in a pissing contest ever since to exclusively license it for $100Ms.

OH: six-seven is a Chinese plot coordinated with the liberal organization dictionary-dot-com to corrupt the English language with nonsense, thereby rendering our LLM models useless

I've been mapping the companies impacted by the AWS outage on October 20th, and trying to find the secondary interdependencies—when companies or services that other companies rely on go down from the outage (e.g. Slack). This is just a snapshot, here’s the interactive version: www.thevoid.community

Outages like today's AWS incident don’t have a single cause. They are the result of countless contributing factors and conditions that cascade through complex systems. While the global internet is remarkably resilient, it is not immune to these dynamics of unforeseeable interactions. 🧵-time!

As our dependence on digital infrastructure deepens, more lives are increasing impacted by the reliability of that infrastructure. We all depend on it, and inevitably, that infrastructure will fail. How quickly and effectively we can recover when that occurs is the key to moving forward.

Christmas of 2012, AWS suffered a similar outage to the same region US-East-1. Netflix’s entire streaming service came down. It’s why we built Chaos Kong. We didn't just accept the disruption and move on. Instead, we changed everything about how we respond to incidents across Engineering.

It's tempting at times like this to monitor dashboards, build up defenses, and dive deep into your technical stack. You'll make better progress if you focus on the impact to your customers, dive deep into your organization's culture, and question how your org chart reinforces your style of response.
