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.
Github is quite a fantastic service for source code management and hosts a suite of wonderful tools which can help you manage the development, tracking issues and much more. One of the fun things is the github activity dashboard located on your personal frontpage which shows how much you’ve done. I’m sure it’s mostly a fun thing and it allows you to sort of get an idea of it the account is dead or alive.
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.
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.
I’ve been having an odd issue for a couple of months. When accessing sites having a .dev domain (like most recently go.dev), I my browsers have given me warnings and as many had HSTS-headers, not allowed me to visit the site. It seemed like a strange error, and I’ve tried to remember if I’ve set up some proxy or VPN connection, that could cause this issue. A few times I’ve asked others on the net if they had issues - which was not the case - and I’ve tried using a web proxy, and everything worked.
