«There are two ways of constructing a software design; one way is to make it so simple that there are obviously no deficiencies, and the other way is to make it so complicated that there are no obvious deficiencies. The first method is far more difficult.»
— C. A. R. Hoare
Welcome to my home on the World Wide Web. This page is about me, Bård
Bjerke Johannessen, also known as Bob to those who have no
Å key on their
keyboards (and even to a few that does). The proper pronunciation of my
first name is also uncomfortably close the that of the English words
board and bored. Talk about bad first impressions: «Hi, nice to meet
you. I’m bored!»
As this page is supposed to be about me, it’s not likely to be terribly exciting. A bit further down you’ll find my résumé, and if you need to get in touch with me I’ve included all sorts of contact information. Unless it’s something urgent my preferred means of communication is e-mail. If you’re in a hurry your best bet would be a short message (SMS) to the GSM telephone number below. Voice calls too easily breaks my concentration and ends up wasting time. My telephone is therefore normally set to «quiet» for voice calls.
