Hello, My name is Mark Wachdorf.
By trade I am some sort of programmer or maybe system analyst, for the sewer district in Sacramento California.
I’ve been there for over 20 years, I’ve taken a lot of notes.
I am slowing moving these notes (in no particular order) to this website.
A lot is obsolete, but I constantly bump into old code, and occasionally have to track these notes down. At least it will all be stored in one location.
