Introduction

These are the notes I take while I work. I also jot down things I get asked about. If you come across these pages, please feel free to use them to your advantage.

You are not allowed, however, to use them in any way disadvantageous to me or my employer. You are especially forbidden to use any information given here to break in to computer systems.

You may find old, deprecated, clumsy, stupid and just plain wrong statements here, which may harm you and your systems in nasty ways.

[Warning]Warning

Your fault if you take my notes for granted.
