I ran across the Japanese concept of ikigai today. There was a Venn diagram associated with ikigai that I found fascinating. I remember when I was younger and trying to figure out what to do with my life I seemed to run across the advice along the lines of “follow your passion” and “do what you enjoy”. But this didn’t seem to be practical. Most of the things I liked to do didn’t pay very well, if at all. I figured you had to find some balance between doing what you like and what pays the bills. I’m probably lucky that I did find something I really liked to do, that also paid the bills. The Diagram below (taken from the World Economic Forum article “Is this Japanese concept the secret to a long, happy, meaningful life?“) lays it out in more detail. Wish I had seen this when I was a young man.

The US announced that the new Frontier Supercomputer at Oak Ridge National Laboratories (ORNL) has achieved sustained exascale performance and is now the faster supercomputer in the world. It is similar to the sort of machines I helped build for the financial services sector, but quite a bit larger. This displaces the previous leader, the Japanese Fugaku Supercomputer.

For some reason this morning the mention of ORNL reminded me of the old country and western group the Oak Ridge Boys. Surely there is no connection. But there is!

The core group that would eventually lead to the Oak Ridge Boys was a country group called Wally Fowler and the Georgia Clodhoppers, formed in 1943 in Knoxville, Tennessee. They were requested to perform for staff members and their families restricted during World War II at the Oak Ridge National Laboratory in nearby Oak Ridge, Tennessee. They were asked to sing there so often that, eventually, they changed their name to the Oak Ridge Quartet … In 1961, Gatlin changed the group’s name to “the Oak Ridge Boys” because their producer, Bud Praeger, thought “Oak Ridge Quartet” sounded too old-fashioned for their contemporary sound.

Frontier supercomputer debuts as world’s fastest, breaking exascale barrier

Was having this discussion with a colleague just yesterday. It is difficult to pull in all the threads that go into the manufacture of something like a modern automobile, but here is a pretty honest reckoning. Takeaway: EV are somewhat more energy intensive to manufacture, but after about 25k miles, the overcome this deficit. My plan: drive less and drive you car (hopefully an EV) longer. From CNET.

Are Electric Cars Really Better for the Environment?

Havent done much in the way of projects lately. In fact, I’ve been dismantling lots of old house projects, including my electrified riding mower and my Raspberry Pi sprinkler controller. We are selling our house, so we are getting rid of lots of stuff, and doing lots of generic cleaning and repair. Nothing too interesting.

A long story with battery powered tools. Bought a 20V Black and Decker battery powered drill many years back. Little did I realize I was locking into future Black and Decker gear. Not a huge problem, but I probably would have bought something different if I had realized this. But I ended up buying a Black and Decker hedge trimmer and a leaf blower. The leaf blower was a mixed bag. Nicer than using a cord, but not much oomph or time on the batteries. Some bigger batteries fixed that problem and I bought a nicer charger.

I was looking to buy a small battery powered push mower, and instead of going with Black and Decker, I got a worx. Had read the 20V batteries were compatible, and the mower came with two big batteries. Well, they were just a little off. Couldn’t make them work with the Black and Decker equipment. Not a tragedy, but would have been nice if everything worked together.

I looked into adapters (there are some available to share batteries on some popular tool platforms). All I could find for Worx was an adapter for home projects. Just the plastic holder and two wires. Bought one and decided to cannibalize an old smaller battery pack and make my own adapter. Not as easy as I expected. Everything inside the battery pack was tightly fitted and even with the batteries removed, I still had to cut away lots of plastic to get the wires to where they had to go. Anyway, in the end it worked. Now I have batteries and chargers that will keep my leaf blower going for as much as an hour.
