In a recent Go programming task I needed to loop through the letters from a to z. I also needed the capital letter from A to Z. For-looping thorugh the letters in Go is luckily a breeze. The easiest way is just using a Rune. A Rune is an int32 which represent a unicode character. As a rune (the variable r below) is a Unicode character, it allows me to use the ToUpper() from the unicode package to find the Uppercase version of the letter.
I recently switch this site from Wordpress to Hugo - and the site with Danish content too. It was mostly easy and straight forward, but initially there was a few features missing (by the very nature of it being a static site) and some things I needed to look into once the switch had happened. One of these was a gallery function to present images (photos mostly). Gallery options…. There are various ways to have a gallery on a site, and one of the pains I had with wordpress, was changing strategies over time, which left me with several plugins needed to handle the historic gallery choices.
Switching to Hugo caused a major change in the workflow behind the site. Wordpress comes with a full-featured backend which allows you to manage basically your entire website (if it’s Wordpress powered), but Hugo don’t. There’s no-backend admin site nor an webeditor to create and manage your posts. It doesn’t bother me. It’s a completely different workflow and I’m starting with a rough minimum flow initially untill I get a bit more expirence running Hugo.
As the web moves more and more to HTTPS and ehanced security (such as HSTS) keeping your certificates updated and valid becomes more and more important. I’m toying with an idea of building a small webapp to monitor my small portfolio of certificates and warn me if a certificate is due to expire. As part of this, I’m slowly patching pieces together in Go and one of the small useful outcomes is a small (compilable to bin) script which prints the basic certificate details of a given domain.
The web is constantly changing and sometimes sites are deleted as the business or people behind it moves on. Recently we removed a few sites as we were doing maintenance and updates on the many sites we run at work. Some of them had interesting content - for personal or professional reasons, and we wanted to make a static copy of the sites before deleting the sites completely. I have not found any easy, simple and well-working software, which can produce and an all-inclusive downloaded copy of a website (including all resources sourced from CDNs and 3rd party sites (to actually make them browsable offline).
