40+ unsaved tabs in Notepad++, mixed stuff, containing keywords about the things I'm working right now, 2-3 line descriptions about an idea or how to proceed with something in the future, copy-pasted and "annotated" fragments of logs or code under reverse engineering (would do most of this stuff by hand but have an awful handwriting). Plus a booklet to scribe quick ideas, play with an algorithm in my head, and draw stuff if that's unavoidable (code graph, state machine diagram).
