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.
daveandersen.bsky.social
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.

It cannot be made clearer.

If you continue to support the Harry Potter franchise in any way, you are directly funding the removal of trans people's human rights in the UK.

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
daveandersen.bsky.social
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.

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

CMU was giving out free mini-pumpkins today so now I have an office pumpkin. 😍 (office not shown)

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.

Um, ICE just coldly shot an unarmed PRIEST in the head w a pepper ball when he (and everyone around him) clearly posed no threat.

For the crime of … complaining about government policy.

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.

Yeah, I use Kagi now and I'm really happy with it.

We stumbled upon this one because my wife still uses Google and was trying to come up with an analogy, and .. well, this resulted. I didn't realize most of the errors, but the Elijah Baley one jumped out at me so I dug in more. Depressing.

and even in the TV series is married to someone else. This is pure slop. Why would you put this front and center as the way you present to users?
daveandersen.bsky.social
Slightly niche, but Google, you should remain hideously embarrassed at having such erroneous shit in your AI summaries.

- The character is married to Toran Darel, not Channis;
-Elijah Baley is from an ENTIRELY DIFFERENT SERIES and is married to Jezebel Bailey (née Navodny).
- Bayta Mallow is TV
Screenshot of Google search results AI Overview:
Bayta Darrell is a character in Isaac Asimov's Foundation novels who discovers the Mule's identity and helps the First Foundation escape the psychic grip of the Mule, though her role in the tv series is different and she plays a central role in stopping the Mule in the books. In the tv series, she is revealed to be the powerful mentalic controlling the Mule, a twist on the original book's plot. 
In Asimov's Foundation Novels 

    Bayta Darrell is the wife of Bail Channis and is instrumental in the discovery of the Mule's true identity and origin.
    She is the maternal aunt of Elijah Baley's wife, Bayta Mallow, in the second book of the Foundation Trilogy, Foundation and Empire.

I regret that I had but one NYT and WaPo subscription to cancel and already fired that shot, because good god, they're both managing impressive new depths.

Anyway, remember to throw some subscriptions to actual good sources of journalism, because it seems they're becoming more rare by the week.

Despite appearances, this is not a @nytpitchbot.bsky.social joke, it's an actual @nytimes.com column by some Claremont hack who praises Hegseth for his "nuanced vision of the military’s purpose and its relationship to civilian society."
