Zettelkasten notes Somewhere during my Ph.D. I started to use the Zettelkasten style of note taking. For my research this was quite useful. Now in my programmer life after the Ph.D. it is less usefull as I can clearly see that it geared towards academics. What is a Zettelkasten? I’ve written a note on what a Zettelkasten is here. Public notes I’ve setup a link between my Zettelkasten repository and this website.
