My latest book—The Skies Above—is a celebration of what we overlook when we look up.

I cover everything from asteroids to hailstones, and even why every rainbow you see is unique to you.

This shouldn't surprise me, but...do people really not have any important numbers memorized anymore?

bleary @bleary.off-the-records.com · 22h

If anyone needs me I will be in the museum, lying down next to the bog bodies.

Did people really memorize phone numbers before cell phones, or is that just a movie thing?
2? Questions
I was watching some old shows from the 90s and noticed people would just dial numbers from memory - like they'd call their friends or family without looking anything up.
Made me wonder if that was actually normal back then? Did people genuinely have all their important numbers memorized, or did most folks keep a little address book or written list nearby?

My big trip is in 19 days and I'm itching to pack already. I would leave for the airport right now if they wouldn't kick me out.

Modern authors are too descriptive. I don't need to know every detail. Let my imagination work or I'm gonna get bored fast.

Blown away by Google DeepMind's performance this year. We'll see if it carries into 2026, but it's been just head and shoulders better than any other model trackwise this season, including the gold standard consensus guidance. Big win for the addition of LLMs 👏

James Franklin @franklinjamesl.bsky.social · 1d

With about 80% of the precincts reporting I've seen enough. GDMI - Google DeepMind is going to win the seat for best track model in 2025. The race for best intensity model is still too close to call, but GDMI is right there with the consensus and OFCL. Quite a remarkable campaign.

I have so many questions, including but not limited to:

1) why
2) what is the cone of uncertainty based on
3) did they predict this 180 days ago
4) why

Out of curiosity, I dove into Canada's climate normals to see how many freezing nights major cities have lost over the past couple of decades.

The answer is...grim.

I am literally willing to spend $18 on a giant sub from Jersey Mike's just to avoid Subway on principle.

Mikki Kendall @karnythia.bsky.social · 2d

The $5 footlong has become the $6 six inch. I don't even eat Subway and I still think it's time to knock all this shit over

This has been a strange Atlantic hurricane season. It seems like every storm fell into two categories: struggled mightily, or reached for the stars.

Here's a recap of what we've seen so far this year:

Hallmark released their Timmy and Tommy ornament today and you better believe I am keeping this out 365 days a year. 🥹

What a weird hurricane season that our two options were apparently a Category 5 or...this.

Today in Extremely Real Autoplay Facebook Reels:

- A corgi gets crushed by a boulder. Another corgi recruits two-dozen groundhogs to eat the boulder and free his friend.

- A man holds onto a helicopter as it lifts off

- A man in an electric wheelchair does sick stunts at a skatepark

A screenshot of three videos on Facebook. One shows a corgi trotting toward groundhogs. One shows a man holding onto the bottom of a helicopter. One shows a man in an electric wheelchair doing stunts at a skatepark.

I'm tempted to get Cities:Skylines II to start over clean with a more modern game, but the price ($50!!!) and mixed reviews makes me hesitate.

Cities:Skylines used to be such a good game. Every update broke more and more mods. Now everything glitches out if you blink too hard.

Have you been yelled at for using red on your color scale? I get at least one a year who's like "use another color, you're purposely making it look scary!"
