Knog Oi Bell

Feb 9, 2021

I was riding with a friend who had a bell on his mountain bike. I never thought that would be something I would do, but with COVID and everyone out walking their dogs off leash with their Beats headphones on, it's a better alternative to yelling to let them know I'm about to pass them. The Knog Oi bell's design is very slick in that it wraps around the bar.

Coloring

I've found new satisifaction in doing colorings to augment reading in the past year. I think I might even be getting better at it.

Site header design

Updated the site header. Anything bad I may have ever said about CSS, I take it all back.

Also, I feel validated.

Kitty Terminal

I've been meaning to mention the Kitty terminal emulator for some time. Since installing it last October it has replaced Gnome Terminal and MacOS Terminal which I use daily. Performance, configuration, customization and documentation are impressive.

GoPro Hero8 as a webcam in Linux

Jan 27, 2021

After all of the time spent in Zoom/Webex during 2020, I found that I needed a new webcam for Linux. When I saw that it was possible to get this working in Unix I did some searching and pieced together the following. The great part about this is that the GoPro is the ultimate multi-tasker. I can use it on my MTB, in my car or as a webcam on my Linux workstation. Big win on this one.

Hello again, world

After many iterations of websites, I wanted something unbelievably simple to maintain due to time constraints. This is just a place for me to put ideas I'd like to share. This site's HTML/CSS layout modified from W3Schools.com blog example.
