A nighttime shot of an opossum in a tray feeder. It looks wet, and one can see the rain coming down.

Opossum eating the last of the peanuts in the tray in the cold pouring rain. At least the hail stopped, but I feel bad for the lil' guy.

I realize I'm now of an age at which "50 years ago" and "50th anniversary of" are meaningless. For example, I have clear memories of the Spirit of '76, Freedom Train, and everything Red, White,and Blue from 1976.

Therefore, it can't be 50 years ago, because that would mean that I'm getting old 🫀

Maybe this is a Midwestern thing, but damn.... Smoky Blackstrap molasses bitters is a whole thing, and I'm here for it.

I continue to be fascinated by the phenomenon whereby an expert engages with any of the LLMs on their field of expertise and is instantly horrified by the wrong answers, and then goes on to use it for things they are not experts in as though it won’t be just as bad for those.

An Altair-Duino Altair 8800 computer to the left, complete with Blinkenlights and switches. On the right is an ESP32 dev board. Connecting them is 4 wires: 5V, ground, serial transmit, serial receive.

Adding a serial to WiFi bridge to my Altair emulator. There's a BASIC program running on the Altair to talk to the ESP32 over UART, configure/connect to a WiFi access point, then connect to a telnet server.

Not perfect, but proof of concept.

Could not agree more, and in fact would extend the same sentiment to users of any LLM/agentic AI bullshit.

Everything may be shitty in this world, but sometimes one just needs to find a beautiful, tropical place to watch the sun go down.

A close-up of a sign outside of a Costa Rican pharmacy. It shows a drawing of a balding white-coated man, likely the pharmacist, holding a cartoonishly large capsule of medication.
