Halloween is approaching. A friendly reminder that a 1.1qt Stanley thermos will hold a bottle of wine + the remainder of the bottle you poured into two yeti wine tumblers. Also if it's too cold for wine, baileys and hot chocolate will also keep well in this combo.

Driving in Ireland is a wild experience. Never mind the fact you have to drive on the left. Even without that it would be wild. The roads are extremely narrow, what would be a one lane road in the us is two lanes in opposite direction.
People park in the road and you just drive around their cars.

“Hades Town” is incredible. I think it tied with “Next to Normal” as the best musical I’ve ever seen.

There are two kinds of travelers. Get to the airport just in time to walk into the boarding line, and the “time is my friend “ type. I’m the latter. Travel days are for me. Time in the lounge. Time alone on the plane. I’d be happy going the whole day not talking to anyone.

I made my son a brass coin. The laser etched it out of a brass blank. Then I ran it through a magnetic polisher and aged it with “Brass Black”.
He loved it. Now he wants to make other coins.

Now that the TSA isn't making people take their shoes off I don't think I can comfortably fly anymore. How will we be safe if people can keep their shoes on?

I have to get the ventilation setup, build the enclosure, figure out lightburn... Or maybe I'll just plug it in tomorrow in my garage and see what happens.

I think it’s incredible that anyone today can easily do business with random businesses on the other side of the world. Including getting multiple quotes and settling on a competitive offer. All from the comfort of my couch.

I connected my smart home to an LLM. Now if someone tries to change the temp on the thermostat, the house reverts the change and then threatens the person. The LLM generates the threat and Alexa says it. Examples:
