Xah Talk Show Topic Notes

This is my topics notes for Xah Talk Show. The show is not scheduled regularly, and the topic is also often decided on the spot. This page lists some possible topics, mostly as my personal notes of things to talk about.

when in a given show we don't have a topic, you can goto Xah Code Sitemap or any of my site link paste the page title in chat when the live stream begin, we talk about that! (posting link usually doesn't work due to Google censorship. so, post page title instead)
