The only good AI chatbots I've used are those whose response to "Connect me to a human" is to actually do that right away.

There were only a few busses home from school every day, and a friend of mine and I were bored killing time waiting for it. I suggested we go to a place some distance away. He thought that it's too far away and we would likely miss the bus. I suggested we'd aim for the next one instead.

Not that closely related, but not having used cash at all for several years, I've started using it more recently, for two reasons. 1. It's nobody's business what I buy, *especially* because it's not shady. 2. Darker - I want payment systems to work even when US payment companies aren't.

I heard someone speak about election security and election legislation many years ago, and they said something I think applies much wider than I realized at the time: «No politician is motivated to change the system that got them elected»

Henry is surprisingly short for his 45 years. A little rounder in the face than you might expect, a little heavier than you might expect, and he is extremely, extremely eager.

Hop cones out to dry. Left: "klev". My first harvest from this plant. Very mild aroma. Not enough for a brew. Not sure what to do with it. Right: "hulla norrgård". Surprisingly citric aroma (a characteristic otherwise mostly found in American hops) and decent bitterness. I will brew with this one
Two framed insect screens are placed on saw horses outdoors.

On the screens are hop cones.

The left has few but quite large hop cones.

The right has plenty of smaller cones.

I don't know when I last bought balsa sheets from a hobby shop, it must've been in the 80s. But now I did and made this completely improvised airplane build. Quite OK, I think. It flies reasonably well.
Cut sheets of balsa on a table. You can see the rough shape of the fuselage and also the wings. There's a tube of glue and unused pieces of balsa.Balsa plane resting on an outdoors chair on a patio. The wing span is 80cm. No control surfaces or balance weights yet.

Plus, the shingles vaccine gives good protection against, well, shingles. According to a few I know who have experienced it, you *really* don't want shingles. It can be extremely painful. I got my dose at the end of last year.

We make equipment, hardware. I, a software guy, was called to a meeting where we discussed cooling airflow impedance matching with plug in boards vs with blind panels. I don't think I've ever felt so unable to contribute anything of value. Basic school physics only gets you so far.
