Day 98: oklab() and oklch()
Anyway, now I’ve added hsl(), hwb(), lab(), and lch() to my tool belt, and along comes mary oklab() and oklch(). lab and lch are great, but not perfect. The main issue with lab and lch is that there's a bug with blue colors which turns blue purple.

The general 'recursive routing' problem in IP networking
The simplest way to break the recursive routing problem is to do the encryption at a level above IP routing. You establish a (TCP) connection, then you have the application level use the connection to arrange an encryption layer and transport your data over that. This is how a huge amount of encrypted data crosses the Internet every day, in the form of HTTPS (and some SSH and other application level protocols). This has the problem that it's not a particularly general solution, and so you wind up with people working out all sorts of ways to tunnel traffic over HTTPS partly because they don't have an accessible, usable general purpose encrypted transport layer they can count on.

Fly a drone by touching Raspberry Pi-connected fruit
Capacitive touch sensors inside Ali’s fruit controllers work just like a touchscreen phone, tablet, or supermarket self-checkout. They’re made with conductive material which responds when touched by another electrical conductor, such as a bare fingertip. When you touch a touchscreen or a piece of fruit with a capacitive touch sensor in it, it draws a small charge to the point of contact, becoming a functional capacitor. The change in the electrostatic field is measured to find the location.

Fixing Rode Wireless Go II RF Interference or buzz
During the reshoot, I still relied on the lav for my primary mic, but it still had the interference, even though I set my phone and iPad into airplane mode, and made sure all WiFi devices within about 20' were powered off!
Luckily, I had the backup track from the overhead shotgun mic... but this puzzled me. I hadn't ever run into this problem with the Wireless Go II before—even in more noisy environments like when I recorded this video with my Dad at a 330 kW radio transmitter site!
