EmacsConf had their 2025 online conference in early December 2025, and I am listening to conference presentations from their YouTube playlist. I thought that the presentation “Zettelkasten for regular Emacs hackers” was a good one. The presenter, Christian Tietze, one of the people behind zettelkasten.de, talked about some zettelkasten principles, and used the Denote package in Emacs for creating new “notes” in Emacs. In addition to the 25 minute talk, he did a Q&A session for almost an hour and a half, which was very illuminating about his zettelkasten process/skills. I have embedded the videos for the talk and the Q&A session in this post – enjoy!
