Rising oil and gas prices? Engie in Belgium started their Happy Hours program today. When the forecast predicts surplus solar power, your electricity will be free for a few hours, to charge the #EV or load up the #HeatPump buffer tank.
Even if there are no solar panels in the house, and without switching to fully dynamic pricing. The prerequisite is a smart meter with real-time reading.
And we are just barely out of Winter.

I'm visiting University of Western Australia as Gledden Fellow for the first time. I must say that Perth and the UWA campus are just stunning!

Even though we don't have a furnace anymore, I still have a bookmark for a price tracker for heating oil. There are some stunning parallels between 2022 (Putin) and 2026 (Trump).

It's always fantastic to visit Prof. Kazuo Kashiyama's CMLab at Chuo University in central Tokyo. I visited over 10 times by now, and every time, it's a delightful experience. Here, we enjoyed demos of an upgraded VR Cave system. Also on the program, German-Japanese Workshop on Computational Mechanics, and Kenjiro Terada's 60th Birthday Colloquium. And on the lighter side, Tokyo Marathon (second time as participant) and World Baseball Classic.

Goodbye, oil heating! We won't miss the noise, the smell, and the soot. No matter how high-tech the furnace is trying to be, at heart it's still a caveman technology.

Another attic find: 12-inch Apple PC Compatibility Card from 1997. Includes Pentium 166 MHz CPU with serial and parallel ports, and a special video cable to switch between Mac and Windows displays. Apparently, I would have to downgrade my PowerMac G4 to MacOS 9.1 to get it running. Maybe a weekend project.

And yet another constant end-of-the-year thing is preparing and sending an annual report to our institute's friends and alumni. This is of course best done before everyone leaves for the break. This year, the alpaca picnic graced the cover.

The other predictable end-of-the-year thing is posting here, on Mastodon only, my latest Wordle stats. It was said that nobody wants to see such things. That may be true, but tradition is a tradition.

Replaced leaking capacitors on another Mac LC 475 board. I’m beginning to like it! Not a dramatic improvement, but the speaker crackle is gone.
