Live Stream #77: Earthquake Data Visualization and more on Star Patterns

[ad_1]
In this episode, I follow-up and improve on the Islamic Star Patterns algorithm using the Law of Sines.

Afterwards I attempt an earthquake data visualization / mapping coding challenge. Spoiler Alert! This one didn’t turn out to well! To see the unedited version of me completing this challenge, view Live Stream #78! (

I also show work from the community.

    Hah, I loved how you were speaking out against contests and then ended the video with a contest. 🙂

    Have to say, though, that like you, I'm all for community participation through means other than competition.

    Great video, Daniel!

    how about u do a program to switch the camera between laptop and the white boards using some kind of sensor automatically for examle if u walk to the white board u set a switch that triggers the camera to switch views
    regards dan love ur work

    I have nothing against the train whistle. In fact I have the same whistle from when I was a kid. I love that thing

    Where can I find the This.Dot song?
    I can't get it out of my head (or the intro)

    What negative feedback for the whistle is he talking about???

    Some days are huge failures in programming. It happens to everyone. And usually on the seemingly simplest of things. 5 minutes AFK almost always solves the problem. It's always good to step away.

    Gotta love that intro 😀
