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):

Someone once said that it is better to burn out than to fade away. However, I believe that in my case, I will do neither. Instead, my brain will lose the will to remain semi-solid, and it will drool out my ear.

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.

It would be awesome if @dieworkwear.bsky.social weighed in on this sartorial conundrum, and more generally, how one should dress for these kinds of "must dress formally" events (in the rest of my life, I basically wear copies of the same black shirt and jeans every day)

I have been asked to testify before the Senate _again_ in a few weeks, and now I am wondering if it is a fashion faux pas to where the same tie in consecutive testimonies only weeks apart.

it is apparently the third oldest continuously operating business in Cambridge, so not off the mark.

I got my first piece of formalwearโ€”a second hand tuxedo for youth symphony performancesโ€”from them when I was 16, and they never disappoint

Yes! If you ever are in the Boston area and need same day tailoring, Keezer's in Cambridge has got your back.

Today was a blur, but at some point earlier in that blur, I testified before the Senate Subcommittee on Securities, Insurance, and Investment.

No, YOU'RE ordering four dress shirts at 8PM in different sizes and fits, to pick up in-store tomorrow, because you have to fly to DC on Tuesday to testify to Congress and don't have a shirt you can wear with a tie.

I suspect that we've been doing the same thing to ourselves for generations.

That's good news. One of the most compelling theories of wolf domestication I have heard is that they *self*-domesticated, at least at the beginning. There was an evolutionary advantage to being less terrifying and therefore able to get closer to the humans without getting killed.

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 onโ€”for 50,000 yearsโ€”until they are basically ridiculous muppets.
