I have a word document that goes with me from job to job. In this doc I have, for example, the first 10 lines of CSS which is always the same on every site I work on. I have browser quirk work arounds, bugs that baffle and how to fix them, plus various other tips, scripts and tricks.

As I come across anything where I say "whoa, never knew that" it's a copy/paste into this doc. Now for the weird bit; half the time I can't remember how to fix a bug but I always know the bug is in the doc and where it is. I have no idea why I can only ever remember the doc but it has saved me (and the companies I work for) countless hours.

You mentioned MX records... I too have no need to know this apart from once or twice a year but each time I use them I copy/paste what I did so I can refer to it again when I need to. My brain seems to bulge and seep with all the information I've learnt over the last eleven years but this doc (which is now 6 six old and updated as needed) has saved my bacon many times over.
