I don't know about the mental part, but physically I'm back from Alaska. While waiting for some sys-admin things to get done last night I wrote a few Unix/Linux tips in the "etc" section of the blog. This includes tips on extracting lines from the middle of a file, determining the free memory on a Linux system, using the nohup command, and displaying nonprintable characters from a file. Busy night.
