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!

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 · 20h

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.

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*

"huh, that's weird" remains one of the most fun things to ever say in research.

Poor old guy got confused about which graph he's looking at

David Andersen @daveandersen.bsky.social · 1d

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 · 1d

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

I put this as one of my grad projects this semester but nobody has taken me up on it. Honestly, this would be a good submarine startup to do -- establish yourself as the go-to consulting firm for 2038 remediation and then prepare to go insane in 2037. Also a good testcase for coding assistants.

I'm kinda positive about the long-term potential of modern deep learning, and I enjoy using coding assistants and think LLMs are a particularly good match there - but it's very, very hard to believe the short-term valuations of these companies.
