I keep a notes folder full of markdown files, one per project or high-level topic to constitute an "engineer's notebook". Then within each file, I add an h2 for each day I work on that project. I would rather keep paper notes honestly, but the power of digital text wins out here quickly. The ability to copy & paste URLs and terminal sessions, and to be able to project-wide search for them later when I can't remember the particular args used on a command from weeks ago. This setup mostly works but it would be nice to have a little more of a software layer on top. For personal notes, I like Day One setup with multiple notebooks and tags.
