For the first time in 36 years, I’m at home, learning for a written exam in business information systems.

Not that I ever stopped learning or sitting exams, for Novell Netware, Cisco or more recently for Suse, but this was all related to my daily work; if you’ve ever sat a Novell or Cisco exam, you’ll know that there’s a lot of memorizing and intense preparation involved.

This time though, I need to memorize content from the 90s, and I’m having a hard time …


HP 35s Pocket Calculator

As part of my first calculus class we were told that we’d need a pocket calculator.

Wait – can’t my phone do that?

There’s something endearing nostalgic about the universities’ insistence on a calculator, and they are in good company with my kids’ school.

My last calculator was an HP 16C, I used it during the first years of my professional life to do bit shift operations, and Hex/Octal calculations; I still have it, alas, it does not have basic calculus functions, such as log(). Time for a new one!

The HP16C uses RPN (Reverse Polish Notation) which makes for super fast and efficient calculations. HP seems to not make any RPN devices anymore, most likely because it’s not taught in school anymore and the customer base is aging out.

Amazon to the rescue! A number of shops had the HP 35s (Model year 2015) in new and original condition for a very reasonable price, and one of them is now mine:


Monday we’ll have calculus again, can’t wait!



First day at University

Today was my first day at University, and also the end of the first part of my journey from being a salaryman to becoming a creator.

Very special day for me, I didn’t really focus on the equipment, so there’s some really shaky bits it the video and also some poor sound – but with all ‘first’ and ‘unique’ moments, there’s no way to reshoot. Well.

Tomorrow is another day, for today this has to suffice
