Took a bunch of jiggling and jostling, but my new cable modem is in, provisioned, and a speedtest shows double the bandwidth of the old modem. Also, it is BLUE.
BLLLLUUUUUUUEEEEEEEE.

Because I have some background in electrical and electronics engineering back in college, I was already somewhat familiar with Nakamura’s work in inventing the blue LED. But this Veritasium video is really excellent in explaining how wonderful this invention was. Plus, the animations are so good that I wish we had these back when we were learning how semiconductors and diodes work.

Impressive lecture about light, near infrared (NIR) to be precise. The need to get outside, to get NIR (so it can penetrate the skin) and its health benefits for all animals, including humans. About the shortage that many are experiencing nowadays, since the use of white LED lights. And the disadvantages of blue light.
Some interesting studies are discussed.
Do turn on the subtitles.
