AlphaGo beating the top human player was in 2016. To my memory, that was one of the first public breakthroughs of the new era of machine learning.

Around 2010 when I was at university, a friend did their undergraduate thesis on neural networks. Among our cohort it was seen as a weird choice and a bit of a dead-end from the last AI winter.

I compare solid-state battery manufacturing, to extreme ultraviolet lithography.

I remember reading about attempts to commercialise EUV lithography in the early 2000s (in a paper magazine!) The same issues that SSB have now - some lucky examples from tiny yields in the lab, but the devil's own problem to scale it and develop reliable manufacturing.

ASML was able to commercialise it in 2018. I expect the timeline for SSB to be about the same, twenty years or so. I think we will see it but not until the 2030s.

Freight trains are mostly diesel, to be fair.

We figured out a system for that in 1881 - electrified railways!

Of course it requires massive capital investment, a modal shift for the last mile, and it's somewhat inflexible.

I really enjoyed "Learn Rust With Entirely Too Many Linked Lists" which engaged me like no tutorial or textbook has for a while.

Anyone remember "The Poignant Guide To Ruby"? That was a fun work of art.

Wow, I'm surprised that Keith Bontrager is quoted saying that quick release axles and disc brakes are not a design flaw.

This is absolutely known as a design flaw! Downhill mountain bikers have known for decades (since say the 2000s?) that combination of brakes and wheels is problematic, and it's known as an immediate red flag that a mountain bike is poorly specced and designed. It is done solely because quick release axles are slightly cheaper. Front disc brakes require a thru-axle design on the front wheel!

I also didn't see in the article, if the Rad bike had cable or hydraulic disc brakes. In my opinion, despite being very common, cable disc brakes are under-powered and unreliable for a heavy consumer e-bike. They are powerful but easily lose their adjustment (I have cable disc brakes on one of my own bikes).

I'm pleased to see someone taking these cheap, bad e-bike designs to court.

At any commercial yacht marina, the wharf will almost look like a Tesla parking lot, with rows of chargers. There's a plug for every berth.

If you do an image search for "marina" you can even spot them on most stock photos.
