I wanted to send a broadcast message over our Google Home speakers, and the Google Home app told me I had to go to the Gemini app to do that. That didn't work, but I did get to have this unhinged conversation, so consider me a satisfied customer.

Playing around with the latest image generation models (via Adobe Firefly, which is allowing unlimited generation until 1/15), and thought I would share how it turned out (results in thread):
Prompt: "Convert the reference photo to an oil painting in the style of Rembrandt.  The regal female Bernedoodle is dressed in a gown with a lavish wide fur collar. Around her neck, she is wearing a heavy jeweled gold necklace with a large ruby at the center. The background is almost black. The brushwork of the painting is visible, with exquisite detail."

I woke up this morning in Manhattan, and I am now in San Francisco, but somewhere in between, I testified before the House Financial Services Committee in Washinton, DC.

OK, so here's the deal, wolf. You can have some of this meat we're cooking by this fire, but in exchange, we're going to selectively breed your children, and your children's children, and so on—for 50,000 years—until they are basically ridiculous muppets.

I miss him. Always will. But as the feeling of acute loss fades, I will also treasure the little memories and reminders of who he was, and I will feel gratitude for all the time we had.

My fingers won't do what I could make them do when I was 18 (back when I practiced every day), but these days I play while enjoying a stiff cocktail made from decent liquor, so it all evens out.

Every time I open this device up, I ask myself "did they let the intern design this?" There is no way that 6 AAA batteries was the right solution here.

another sign: my wife texted a picture of this crazy box Marriott sent, which is waiting for me at home. I am curious what the object on the right is (crystal paperweight?) but I don't want to spoil the surprise

I found the best sign.
A sign with various things crossed out: a burger and bottle, something about back packs, a hand reaching for a skull that has emanating lines, someone drawing on a skull with a marker, a camera flash, etc.
