I can't imagine this is actually going to have any effect but I enjoy yelling into a box that's ... going to be summarized by AI into something that encourages some google PM to keep stuffing more AI down people's throats

They didn’t just NOT give Trump the Nobel Peace Prize, they wrote a citation that reads like an anti-Trump rallying cry.

'When authoritarians seize power, it is crucial to recognize courageous defenders of freedom who rise and resist,' the Norwegian Nobel Committee said as it announced Maria Corina Machado as the winner of the 2025 Nobel Peace Prize

HELLO TECH PEOPLE

May I please have a bookmark with RFID and a home-base device that will make it bleep when I’ve lost the book I was reading & need to find out what happens next?

Thank you and good evening to you and your families!

Sounds like they should have put on one of your hats and a sweater instead.

If you told me 20 years ago a phone could actually capture an ok-ish shot of the moon I'd have said you were crazy.

David Andersen @daveandersen.bsky.social · 2d

Modern cell phone cameras+processing delight me. I'm also glad I could turn the "AI enhancement" off. I like the shot without bullshit, even if it's a bit fuzzy because it was taken through a device that fits in my pocket. (Last night's moon viewed from Pittsburgh on a pixel 10 pro, handheld).

A cropped shot of the moon. The usual moon details are visible though a bit fuzzy. There is a ring of noisy light mush underneath it that was probably due to camera shake.

that is better than what I've seen before, but note that they're still saying somewhere around 15k miles for the breakeven point. That's great for my family, though - the old numbers had us at 12 year breakeven (meh), those have us at 4 years. (Ironically, the e-bike lengthened our break-even time)

And if you're faculty: I beg you, for the sake of everyone else in the world, strongly consider creating your own public webpages for your course instead of having everything locked up in Canvas.

David Andersen @daveandersen.bsky.social · 2d

We will regret sacrificing the open web. I was curious about which courses at CMU use the Ed discussion platform. So I did some link: and site: searches and a little crawling...

A huge number of the course websites are locked up in Canvas and even as faculty I can't see them. *headdesk*

Yeah. And my hope is that the CO2/pollution cutoff moves earlier as we (hopefully) keep improving the mix of our electrical supply. Ahem. PJM, are you listening?

This is the single biggest reason we'll be getting an EV as our next car. We drive so little that the environmental benefits are a wash. But almost never having to go to the shop or gas station is incredibly appealing.

jamelle @jamellebouie.net · 3d

i’d say the real killer feature of EVs is basically the lack of real maintenance costs.
