Alrighty, ready to see something really cool? (and maybe a little nauseating)
The evolution of Hurricane Melissa's mesovortices at peak strength.

It’s Sunday and I’m trying to catch an 8-minute connection from BART to Caltrain at Millbrae. BART arrived on time at SFO but departed 7 minutes late for Millbrae. Will there be enough time for the time-honored Millbrae escalator sprint?

MAJOR NEWS: @GavinNewsom signed SB 79, my bill allowing more housing near public transit — rail, subway, rapid bus.
It’s a huge step for housing in California. It’ll create more homes, strengthen our transit systems & reduce traffic & carbon emissions.
Thank you, Governor!

@governor.ca.gov it’s time to sign SB 79. Are you a governor of the people, or of the landed gentry? Tell us.

In German, “secret state police” translates as “Geheime Staatspolizei” which is kind of a mouthful so it can be shortened to Gestapo
We don't have secret police in America. At least we're not supposed to.

Millions of Americans drive two-ton vehicles impaired, far above speed limits and play with phones—law-breaking causing tens of thousands of death and solvable with current tech and real enforcement.
Anyone blathering about capping e-bike speeds in the name of public safety is not a serious person.

The Lunacy of Artemis
For the first time since the 1960's, it looks doubtful whether the US space agency is even capable of getting us to the Moon.

I wonder which neighborhoods GenAI will recommend we destroy @segbydesign.bsky.social
California has more super commuters than any other state, with over 300,000 people spending at least 3 hours a day on the road.
By using GenAI to pinpoint the worst traffic bottlenecks, we hope to find real solutions and make these commutes faster and easier.

After a power source reaches 100 TWh -- basically, after it gets out of the larval stage -- how long does it then take it to reach 10x, ie, 1000 TWh? How long to 20x, ie, 2000 TWh?
