Have any of you folks tried hosting the code for https://gettogether.community/ ? It's a python based federated gathering organizer a la Meet-Up.
Looks pretty straightforward but I haven't tried it yet.
The orchid mantis is a big weird lanky bug, which is relatable, but she also rocks high-femme fashion while being a terrifying predator with swords for arms, which is aspirational.
This is unbelievably awesome

Thanks to UKClimbing.com I had a database of over 427k rock climbing routes to feed to a neural network. It did pretty well. http://aiweirdness.com/post/175339699997/blue-boulders-problem-1-more-rock-climbing-routes
.@mhall119 is developing an ethical alternative to #MeetUp called #GetTogether.
There's already a flagship site up and running:
https://gettogether.community/
The dev is working on #ActivityPub support and is requesting feedback on what more needs to be done:

One fun thing I discovered about Visual Chatbot: no matter what the photo is of, it will always report there are at least a couple giraffes.
It learned from answers that humans gave, and apparently nobody ever asked "how many giraffes are there?" when the answer was zero.
The keyboard had no arrow keys, so we vi'd in hjkl mode. The terminfo was incomplete for our terminal, leading to screen artifacts as we debugged. The compiler was for K&R C, which led to further confusion.
This led to many jokes about how many engineers it takes to clear a screen.
For posterity: the magic incantation to clear the screen is 0x1b 0x0c.
That and a for loop made a nice screen saver to show off Tektronics' demo plots.
To display a plot, just cat the .plt file.
After poring over the docs (a PDF scan of the manual from 1970) we figured out how to clear the screen programmatically: emit ESC+FF. We wrote a C program to do that.
There was some disagreement over whether that meant 0xFF, a literal FF, or something else. Turns out they meant ASCII Form Feed, or 0x0c.
There is a button that clears the screen. If you don't push it between plots, it builds up screen junk just like an unshaken etch-a-sketch.
Tektronics 4014-1 vector memory terminal. It has no actual memory, but the screen is persistent like an etch-a-sketch.

Ah, the Digital VT100. I learned pascal on one of these back in high school!
