Talking to Dynamixel servos from a NVIDIA Jetson (or other host computer)

It's pretty common, among people who want to talk to Dynamixel servos like the MX-28 or MX-64 or AX-12, to try to use a built-in UART on whatever computer they're using. Raspberry Pi, Odroid, NVIDIA Jetson are just a few common choices. The first thing an engineer will wonder is: "will I break something if I just tie TX and RX together on my UART?"

Actually, tying TX and RX will work fine, as long as you know to receive and discard the bytes you are sending yourself. There are two other problems, though:

Subjective does not mean arbitrary

In the discussion of compensation, and using subjective judgments by the compensator to the compensee (employee,) one frequent question is "how can subjective evaluation be fair?"

"Subjective" does not mean "arbitrary"

Some examples of images to classify

The question came up: Why would I go through the trouble of training a neural network, rather than just checking "is the ground in front of me gray-colored?"

Machine learning and computer vision for autonomous rover racing -- step one

Some interesting news on my project to apply machine vision to the subject of autonomous rover racing.
I've been renting GPU processing power on the GPU processing power spot market (yes, there is such a thing) and training neural networks.

How to harden a publicly facing server

The question came up: "How would I go about 'Hardening' the host server?"

In theory, hardening is a simple mixture between good configuration, good software, and good operational practice.

Enchanted Age Privacy Policy

Enchanted Age is just me, Jon.

I don't sell e-mail addresses for spam. I don't collect birthdates and correlate with home addresses to try to guess social security numbers. I generally don't do much but sometimes, when I have some free time, build a simple game and put it up on the Google Play Store.

How do I dependency?

So, if I were to build a brand new OS, not based on Linux kernel necessarily, what should packaging look like?

Look what I came across

In the distant past, I made an effort to get various virtual world vendors to attempt to interoperate, such that various virtual worlds could be interconnected.
That would have been cool! Unfortunately, the competetive landscape ended up not supporting such an effort.

Here's a copy of the IETF draft that I posted at the time:

Using the OpusFile library with Microsoft Visual Studio for Windows

The "opus" codec performs pretty well across a wide range of bit rates. When doing voice chat over the internet, or streaming music, or even including compressed music for a soundtrack for a game or other application, it is a pretty reasonable choice. Especially since it's free, as in beer!
