Today, August 4, 2026, is the setting of Ray Bradbury’s short story “There Will Come Soft Rains” about a fully automated house continuing on after the family who lived there and the world around it died in a nuclear blast.

More than anything, this illustrates a way that math can fail to capture real value. Anyone who has taken a probability course can compute "expected value" and smile smugly (some people make a career out of it), but that assumes that all dollars are equally valuable.

Overall, I can't say that I liked Nolan's The Odyssey BUT I did laugh out loud at how many times the screenwriter showed off that he had read the wikipedia article about the Bronze Age Collapse. I'm gonna be laughing for days at Matt Damon solemnly saying "Our Age of Bronze is collapsing"

If we were part of a sci-fi style galaxy-spanning civilization, this would be one of the things Earth would be most famous for. Every solar eclipse, we'd be swarmed by obnoxious tourists for the galactic core with no respect for local customs. Get your selfie and stop slumming it in the Orion Spur!

eclipses are bonkers though. Absolutely wild odds that, from our perspective, the moon is the same size as the sun. blows my mind every time I think of it

Absolutely losing it that there's a serious neurological condition called "Todd's syndrome". Imagine going to the doctor, who looks gravely at your test results, and then looks up and says "I'm afraid you've got that thing that Todd had"

Ok, this is very funny. AI generated a marketing campaign for Starbucks which was themed around a brutal anti-democracy massacre in the 80s, and no human stopped it. One of the slogans directly referenced the death of a student by torture! www.theguardian.com/world/2026/j...

How a Starbucks marketing stunt spiralled into mass boycotts in South Korea

A botched tumbler promotion on the anniversary of a pro-democracy massacre unleashed a boycott, police investigation and political firestorm

Google docs rolled out new logos. Today of all days! Normally, I'd need a day of recovery to process and heal after something like this, but it's the first day of NA South Playoffs, so I guess I'm just gonna have to roll with it.

There is truly no email more threatening than the "It's almost time for your flight to [blank]!" email that airlines send out. Fuckin' chill! I have a dozen more on-fire things to worry about before I even START worry about that flight.

I like how the US has backed into a form of socialized media every April, where we pay a portion of our taxes to TurboTax every year, which they use to fund virtually all media via non-stop advertising blitzes.

Sometimes when I tune everything out and just skate, everything clicks into place and I feel like "ohh, this is what my body is meant to do". Making it do chores, or socializing, or emails, or threat assessment...of course that never works right. Body is machine that turns music into skating.

Prediction markets are such a vivid synecdoche for the illness of late capitalism. Not only do they lay bare the rampant gambling addictions at the heart of the tech and finance worlds, but the insider trading is so obvious that anyone participating must be assuming there's a greater fool to scam.

Is there a worse word in the English language than "eighth"? Spoken, it ends in a strangled tetragraph, as if garroted midword. Typed, it alternates hands on off-home keystrokes, practically guaranteeing a typo.
