You have found the personal technical notes of Chris X Edwards. These notes were mostly created for my own reference and for my friends. They are posted publically in the hope that they might somehow be useful to someone. Bear in mind however, that these are only rough notes and are not guaranteed to present the best way to solve any particular problem.

If you find a flagrant error that you feel should be corrected, feel free to contact me and let me know (send email to "help" at my domain which is "xed.ch").

The notes are created with AsciiDoc and there is always a plain text version available by just adding a .txt to the URL. The original date listed was preserved from old notes so that I could keep track of when the document was first created. This doesn’t necessarily imply my first exposure to the topic, but rather the first time I was frustrated enough at forgetting the details I needed to remember.

Whatever your problem that brought you here, Good luck!
