Meeting Schedule

=========

10:30 --- Interrupts on ESP32 --- Ting
"I owe Don Golding an interrupt service routine for his AIbot. Without a robot board, I built an RGB Lightbox with a NdeMCU ESP32S kit. It has 4 potentiometers to control a white LED and an RGB tricolor LED. Every tenth of a second, ESP32 is interrupted. It reads 4 potentiometers and drives 4 LEDs with PWM accordingly. It can be incorporated into robot code for its instinct level programming."

The Acoustics of Chinese Bronze Bells
"Since I got my audio recorder and FFT working, I revisit my work on Chinese Bronze bells. With FFT I can determine the base frequencies of my bell and the two bases frequencies are accurately measured. I will bring in my bell which is very heavy, about 100 lb. You can all hit it and listen to the sound."

11:30 --- Lunch ---
The Treehouse will be open!

13:00 --- LOCKPICKING IN FEBRUARY ---
     Before we start the stream, we'll have a short teaser for the upcoming event in February.
     Bill Ragsdale is the Dean of Instruction at the Academy Of Lock Picking Arts.          He presented a short overview of a session which will be presented at the February meeting! It looks like it will be a lot of fun!!
     In order to get a sense of the hobby of lock manipulation, go to YouTube and have a search for "The Lockpicking Lawyer".   Confirmed reservations required.

13:30 --- Introductions, Rumors, Gossip, Slander, Libel

14:00 --- Connecting Forth to the World --- Brad Nelson
"I'll describe my journey migrating flagxor.com from AppEngine toa Google Cloud server running Nginx and Forth.Along the way I'll discuss ways to plug Forth into Linux syscalls,processes, forking, pipes, semaphores, and sockets.We'll learn about SCGI, certbot, Let's Encrypt, and more."

15:00 --- Break ---

15:20 --- An Alternative Approach to Literate Programming --- Samuel Falvo II
"I wrote a literate programming tool in Forth, but it's not Knuth-style literate programming."

15:50 --- Clean Up, Log Off, Reset, Adjorn

===========

     We try to stick to the schedule, in particular on Forth Day. Remember that schedule slip is sometimes unavoidable. If a guy's on a roll, one wouldn't want to interrupt.

      Once in a while we shuffle things around, for whatever reason. It may be ill-considered, but it isn't malicious.

      If you're desperate to see a particular thing at a particular time please mention it and we'll try to accommodate you. If we get enough of this sort of request, we'll institute a system of graft and corruption in order to accomodate the well-healed among you.

_______________________________________________

     The schedule above may be reformatted or line-justified but please transmit it verbatim and in its entirety or not at all. A link to this page is preferred.
_______________________________________________

     No Newsgroup posts or other media distribution please! Contact me and we'll discuss it BEFORE you proceed.
