Cert Monitoring

Everyone knows the alert when visiting a website with expired certificates. At least once a month I stumble into one or I receive tickets with questions asking what to do. “Nothing” is my reply in most cases. “The mistake is on the other side”. On this occasion, my very special appreciation to the owners and/or administrators of such sites for the extra work required.

Hugo as Web-Developing Platform

Making of blog.jakobs.systems At the beginning of the (first?) Corona lockdown in March 2020, I was advised during an nightly Jitsi meeting by a befriended admin from Hamburg about giving Hugo a chance. Probably just after I dropped a rant about Rapidweaver, my previous static site generator on the Mac. The idea needed to grow for almost half a year, till August, when I finally found a test balloon for Hugo: My personal blog and if everything succeeds, my official website, which is slowly getting rusty.
