”The car ate road and blew miles out of its tailpipe.”

Such a wonderful line from Stephen King’s The Stand. I think this one will replay in my mind whenever I’m on a long drive next.

And now I’ve just renewed my Audible subscription and downloaded Stephen King’s The Stand.

I’m 236 pages (just started Part 2) in to ”Seveneves” by Neal Stephenson and I’m absolutely loving it. This is the kind of nerdy topics, full of even nerdier digressions that I love.

The Moon blew up without warning and for no apparent reason. It was waxing, only one day short of full. The time was 05:03:12 UTC. Later it would be designated +0.0.0, or simply Zero.

Neal Stephenson, Seveneves

That’s a great opening to a book.

(The lawn needed mowing today, so I bit the bullet and started listening to this one.)

The reading continues. After finishing Life 3.0 I resumed my listening of Neal Stephenson’s Fall; or Dodge in Hell. This one is a wild ride. Such an interesting premise and great start, then kind of slow for while and now (Prim’s journey) it’s great again.

Also I’m currently reading Max Tegmark’s Life 3.0 and I can’t for the life of me decide if I really like it or if it’s really tedious. Perhaps both. The first few chapters where great but as it goes on it really goes on, and on, and on, and on.

Moreover1 it discusses a lot of similar topics, and based on similar sources, as Kurzgesagt – In a Nutshell. That is both a good thing and a bad thing. It’s interesting to nod along to things I already knew from Kurzgesagt, while it’s also tedious to be told things I already know from Kurzgesagt.

As you can tell, I’m really mixed on this book so far. Currently I have a little over two hours left on it.


  1. Life 3.0 should be subtitled ”Moreover, the Book”, alternatively it should be accompanied by a drinking game in which you take a shot for every ”moreover” in the book. You’ll be braindead within a chapter.

I just realized I left the story of covid-19 in the family unresolved, and that I haven’t blogged for over a month. Anyway, I got a total of two tests while Linn was covid positive but both my tests came back negative. I’ve been meaning to get an anti-body test but haven’t gotten around to that (yet?). So it’s quite possible that I didn’t have covid. All we know is that Linn had it, that Iris might have had it, and that I maybe possibly had it.

Linn got better after a few days and hasn’t had any long term effects, so we seem to be in the clear.

Now spring is here and the summer seems to be right around the corner. Lot’s of things to do.

The first day with the πiFi was a great success yesterday. The kids caught on to how it worked immediately and listened to a lot of music.

Finally, I have the first proper beta of the πiFi Music Player working. The enclosure is 3D printed and fits nicely and the software works more or less. Tomorrow I’ll ”release it to the public” (aka the kids) and see what happens.

This large wall hook 3D model is really useful and has helped me clean up the power chords on the side of the house where we park the cars.
