Linux – 360 degree video editing on Linux
I recently purchased a 360-degree camera that I have used a few times. It takes 360-degree spherical photos and also films in 360 degrees. It’s not the most expensive such camera, but it does a decent job shooting 360-degree panoramic videos. However, I have run into a couple of problems with the resulting footage on…

R (Linux) – basic installation
To install the R programming environment on Linux is pretty straightforward, but it does require a little bit of know how in order to find the correct packages.

Switzerland – remaining adventures

Iceland – final post – drone footage
I took my drone to Iceland with us. I knew that there were lots of places where I could fly the drone and it seemed like the ideal opportunity to take advantage of the drone to get shots we couldn’t otherwise get. Here’s my Iceland drone compilation:
