Follow-up to A Survey of Personal Wiki Software

Since then, I have tried some more methods. Eventually, the one long document was broken up into many short ones. I had one or two for each course and often liveTeXed in class. Occasionally I would add hyperlinks between the documents (they were placed in the same folder). I would actually read my notes and refine them. I also put homework problems in those notes. But after a while, this again became too difficult to manage: there were just way too many documents to juggle around with. I also felt like there was just too much text that I will only read very rarely ever again. It felt pointless. I mean, the books are there. If I wanted to record my own thoughts, I could just vaguely explain the context in a few sentences and then write out my thoughts.
So this is essentially what I’m doing now. Obsidian is pretty good. I’m not sure if it is a new feature of the latex suite, but now one can add a preamble (of course, you can’t include packages, since this is mathjax and not full latex). The paid Obsidian sync addon is also decent: after I upload a picture to a note, it gets synced to my laptop quite quickly. This workflow for taking notes feels quite nice.
