Currently I am experimenting with the Zettelkasten method for writing notes. I just want to share some of the books that I am reading and the software that I am using:
I use TiddlyWiki to store my notes. It is an incredibly flexible personal and portable wiki. It has been around forever, is open source, and will hopefully have some staying power.
It can be a bit hard to get to grips with how it works. To really get going with it, Grok TiddlyWiki by Soren Bjornstad is required reading.
In principle TiddlyWiki is a single file, which you can sync between different devices. I need a solution that allows me to seamlessly switch between my laptop and my phone. TiddlyPWA seems to do the trick. It turns TiddlyWiki into an offline-first Progressive Web App, keeping my notes synced through a server that only every sees my encrypted data.
