Sure, but as long as it is digital plain text files. I've tried the minimal paper setup and it got to the point where: - Recall was terrible (both in-notes, i.e. no quick search and physical notebook misplaced at the most incovenient times) - Insane amounts of duplication (no easy linking to old notes) - Unshareability (couldn't lend notebook to colleague as it was personal, had to type it anyway) - No redundancy (dog ate notes) I now have a digital text file system. Although it is not a "NASA project", I can add searchability with basically any tool, easy linking (with tags or wikilinks to dates, topics, etc), copy-pasting and proper backup. It is portable across devices and OSes and allows me to perform simple (and complex) analysis with simple scripts if I need. Being simple text, I expect this system to scale for the rest of my life.
