Where/When will this be? For my interest making some of the low level processes more understandable would be great. Recently I came across a sysadvent article on stracing 'ls' it was exactly the kind of thing that is useful to me. (quite probably an HN or reddit/r/programming link) Also in the "Land of Lisp" book learning what the bit operator 'ash' does was a real eye-opener. Both of these things are pretty basic for someone with a CS or EE background. But I think a lot of sysadmins come from other backgrounds. A bit more than a decade ago I was a grad student in a Literature department and found myself inexplicably attracted to Linux, OpenSource and started to try and extricate myself from Windows gui-ness. Eventually landed a sysadmin job about 5 yrs ago after taking some CS courses and some DIY learning. In short I have real weaknesses in math and low level understanding of what is happening at the kernel level - I really treasure things like the 2 mentioned articles as they shed light on what is going on at a lower level.
