Do you keep a work journal/diary? How?
I'm starting a job soon and want to try doing this for myself as I'd like to be able to reflect on what it is that I do. One obvious solution to this is a bound paper notebook and pen, which have nice properties of taking both text and images easily with pen or pencil, but suffer from not being searchable and are yet another thing to carry. Also, as a software engineer I find I can type much faster than I can write.
Another option I'm investigating is using emacs and org-mode, but I haven't found a way to nicely embed images into emacs besides ASCII art with artist-mode, which I find to be relatively crude for the sort of sketching I typically do.
How do you guys go about journaling for work? If you include images along with your text, how do you do it? Bonus points for lightweight or portable solutions.
