About the author

Hello! My name is Jörg Hau and I'm living in one of the most beautiful parts of Switzerland: Near Lausanne.

I have a university education as analytical chemist, holding a Dr. rer. nat. (Ph.D. equivalent) since 1994. A 14-year career in industrial R&D brought me in touch with a number of very diverse fields: fundamental and applied research, scientific instrumentation, software development, project management, quality management, management, training and coaching.

The experience that I acquired over the years will be of value for more than one company - therefore I founded my own Consulting business, Quality-Coach.ch, in 2009.

Since early 2009, I am also owner of the Swiss branch of pfranc.com, providing plugs and cables - primarily for Garmin GPS receivers - to individuals and to companies.

You can also find me on LinkedIn. I am not on facebook.


To get in touch with me, simply write an e-mail.

A few questions that I receive pretty regularly:

Gibt es auch eine deutsche Version dieser Website?
Obwohl ich einige Seiten in Deutsch und/oder Französisch übersetzt habe, lautet die Antwort "Nein". Der Hauptteil meiner Leserschaft kommt aus dem englischsprachigen Raum, und eine Fassung kann ich noch bequem in meiner Freizeit warten. Wenn ich dazu aber noch eine französische und eine deutsche Fassung erstellen und vor allem aktuell halten wollte ... nein, es gibt wichtigeres, als jeden Abend vor dem Rechner zu verbringen ;-)
Is there another language version of this website?
Albeit some pages of this page are available in German and/or French, the general answer is "No". Most visitors of this site are from english-speaking countries and this is the version that I can keep updated fairly easily. Adding one or more versions in other languages would consume too much of my free time ... life is more than just sitting in front of a computer ;-).
I am trying to open a file from your website, but I'm getting an error message like "Error reading header ...". What am I doing wrong?
Most of the archive files that I make available on my site are in gzipped tar format, either with the extension .tar.gz or .tgz. From time to time I get reports that these files "do not open" in Winzip under Microsoft Windows XP; the reason is apparently that either Windows XP or Winzip breaks the filenames if you try to open a file on-the-fly. As a workaround: Right-click on the link, "Save Target as ...", and most important: make sure that the file extension is preserved correctly! You can then open the downloaded file normally (Winzip will probably unpack the .tgz to a .tar first, which you have to unpack further).
