My new blog using Hugo

I recently made the switch from a self-hosted Wordpress-powered blog website on a Docker VM in Microsoft Azure to a statically generated blog website using Hugo, hosted for free by Netlify. The reasons for doing so are that Wordpress… had a long due PHP 5 to 7 upgrade that was giving me headaches (running Wordpress in docker didn’t help me much here because of the way it was set up) kept breaking once in a while mostly because plugins would fail or start behaving differently made me constantly worry about security, given its history of exploits required plugins and tweaks to get an A-rating on Pingdom tools So after my employer started shuffling with the Azure subscriptions they offer their employees, I decided to go with a statically generated blog, generated by Hugo, which is:

Using multiple GPS tracklogs to create artistic views in Google Earth

Since June 2005, I’ve been collecting tracklog data using my (then) Garmin GPS 60 (CSx). This means that every time I go cycle racing, walking, sailing, ice skating or even flying, I bring my Garmin, turn it on and (automatically) log the track.
