New on Chartwork: the behind-the-scenes story of The Prosperity Gap.

Trump prevented everyone from celebrating near the game. He made everyone show up hours early. Women could not take in a bag. He inconvenienced the entire city. And then he fell asleep.

Gearing up for the SpaceX IPO on June 12? @DFosterGraphics and I made you a couple of handy charts
Space launch is the core business
Starlink Internet service is the only profitable part
Most capex spending goes into AI
Also it will be classified as an industrial firm, not a tech company
And it won't be in the S&P 500 index for years!

The stock rally has created so much wealth in the last 12 months that if split evenly among all US households it would be more than $100,000 apiece
Are you getting your share?
Most Americans aren't

America's wealth grew 742% since 1989.
The richest 10% captured most of it.
We built an interactive that shows exactly how — scroll through 36 years of data on stocks, real estate, and who owns what.

GitHub just dropped something wild.
A system that forces AI agents to write full specs before touching a single line of code.
95,000 stars in days.
The idea is simple but brutal:
No spec → no code.
The AI has to plan the entire architecture, define all requirements, and document edge cases BEFORE it's allowed to build anything.
This flips how most devs use AI agents today.
Most people just prompt and pray.
This makes the agent think like a senior engineer first.
The result?
Less hallucinated code.
Fewer rewrites.
Agents that actually ship what you asked for.
This is the shift everyone saw coming but nobody built until now.
Spec-first AI development is about to become the new standard.
And the 95K stars in 72 hours?
The market just told you what it thinks.

Colbert and Letterman brought back Dave’s "Destroying Stuff" bit from the roof of the Ed Sullivan Theater one last time….and Dave with an epic goodbye for CBS:
"In the words of the great Ed Murrow, 'Good night and good luck, motherf*ckers!'"

I mapped all 2,236 of my LinkedIn connections as an animated D3 network — 30 years of journalism, dataviz, and a parallel life in music. Every dot is a real person.

This is the most pernicious economic trend in the United States
Working and middle class share of wealth hit a record low during Trump's first term, and is heading for an even lower low in Trump 2.0
Trump's "golden age" only exists for the rich
