Don't know if you guys know about this mailing list called UNIX Guru - but it is a very nice "Tip a day" sort of list. No BS, ads, etc. I have receivedd it for the past two weeks, and already I have learned a lot I did not know. These are just the sort of tips us macosxhints.com readers love. The kind of stuff you grab and throw in your goodie bag for the day you might need it. You can view the tips and sign-up for the newlsetter here:

PS - I am in no way associated with the list, just a happy subscriber.
[Editor's note: This was mentioned in passing in another hint, but I felt it worth mentioning on its own merits.]
