This is definitely a pipe.
You can tell because it looks like a pipe.
And if you don't think it's a pipe,
Just wait until the next model comes out.

Book review: if you're a leftist, you should read this. It does a good job of explaining historical attempts to establish socialism, and outlines what any transition is going to have to contend with in the coming years. My takeaway is to root for the end of US/EU imperialism, but there's a lot more

LZ saw one candidate dark matter interaction in 2.8 tonne years of exposure. Which is interesting! But particle physics history is full of 3 sigma events that disappeared with more data (which they are collecting)

Book (re)read: Rainbows End by Vernor Vinge Set in the far off year 2025, it interestingly imagines what humans will do as everything online gives everyone access to specialist knowledge and manufacturing. It tells a good story, but don't think too hard about sociopolitical implications of the tech

the concept works, but it was a pain to thread the LED strip through the cord. I think I can make that easier if I can find some plastic tubing in the right size what I'm going to do with it, I've got ideas, but stay tuned to see if they work
