discovering kivy on raspbian buster and the rpi4B

3D render of Blender monkey using Kiva

Because of a chance comment on an earlier post (an absolute failure – unable to build qt5 on a raspberry pi 4, https://arcanesciencelab.wordpress.com/2019/09/02/an-absolute-failure-unable-to-build-qt5-on-a-raspberry-pi-4/) by developer outsourcedguru (https://outsourcedguru.wordpress.com/) I have “fallen” for yet something else to get involved with: Kivy (https://kivy.org/). To be honest I’d never heard about it before now. It uses Python like PyQt5 does, to provide the programmatic bones on which to build very interesting applications using other tooling for desktop application rendering, which is 3D in this case.

I went looking and found directions for getting everything installed for Kivy. I then found a GitHub repo with this example in it (https://github.com/kivy/kivy/tree/master/examples/3Drendering). I downloaded everything and got it going as-is. It is now my new favorite thing to just run on my desktop. I’ve been monitoring both CPU usage as well as memory usage, and with this simple example it has basically no impact at all. Startup is near instantaneous. CPU temperature crept up a few degrees C, if that. With Chromium open with fourteen or so tabs and my other tools open as well, it should be doing some kind of work.

Something else for me to explore. I’m going to pull this onto my Macs as well.

dorian moves on

This is my last Dorian-related post. We had a lot of wind last night, and rain most of the evening, but little in the way of accumulation, perhaps all of two inches so far. Dorian is doing far more damage along the Florida coast, but not as much if it had come ashore. And did I mention how slow Dorian’s moving? Compare this screen capture with yesterdays, or further, look at the National Hurricane Center’s forecast tracking maps and see just how off all of them have been with regards to where Dorian was forecast to be, especially today? Late last week it was forecast to be all the way up the east coast of the US. Instead it hasn’t even passed by Jacksonville yet. And its overall wind speeds have dropped it down to a category two, if not a category one, hurricane. So we can be thankful for that.

Now begins the long repair and rebuilding down in the Grand Bahama and Great Abaco islands.
