This might not be useful to anyone else but my SSH key on my web host, NearlyFreeSpeech.NET, recently quit working. I first noticed it when my deployments on DeployHQ were failing. Long story short, it seems that OpenSSH recently invalidated certain (weaker) RSA keys. I made a personal note about how to create a custom keypair and upload it to DeployHQ.
I wanted to share the note with someone so I published it. I haven’t shared this yet but I recently created a system for publishing my plain text notes to an 11ty site. I wrote the code in a very this-is-just-for-me manner (home-cooked you might say). Maybe eventually I will cleanup the code and release it. Plenty of apps have this note-publishing functionality but I like the idea of my notes being on my own website that I control.
