Another year, another retrospective. This is a brief summary of interesting things that happened in 2021. Written mostly as archive content for myself. Includes broken bones and questionable wood working.
Boggle is a word search game where you find words from a 4x4 letter grid that no other player has found in that round. This post talks about some of the interesting parts of building a Boggle solver website.
I've been surprised how much use I've got out of the SIP Diagrams site. This post covers a couple of follow up tweaks to improve the experience.
In my 2020 Summary blog post I touched on the Azure DevOps built-in wiki and how well put together it is. One of the best features is the support for graphs via mermaid. I do however often find myself creating a new graph by copy/pasting from the last mermaid SIP flow graph I edited.
I have an old article (Jan 2019) about how I managed to get a Let's Encrypt SSL certificate on my Synology NAS. It's a hack built on a hack (liberal use of `chattr +i` for example!), but it has mostly worked fine for the last couple of years. However, when the cert recently came up for renewal it failed. Instead of fixing, a quick Google search shows there are much better options available now via acme.sh.
