Posted by jpluimers on 2016/02/04

We just purchased an iMac yesterday to view our travel videos. The thing is, all the videos we have stored on our external Hard Drive are in the .MTS file format (AVCHD). The thing is, the Mac or

When your license check is faulty and causes customers to loose work it’s a cardinal sin

Posted by jpluimers on 2016/02/04

I wrote about this before, named it a cardinal sin too, but I seem to have to repeat this:

When your product thinks the license is validate and quits without allowing the customer to save its work, then you’ve committed a cardinal sin.

Yes, I can talk about cardinal sins: I’ve been named after the artist Hieronymus Bosch (:

For me it is OK if a product checks for binaries that do not to the product (and not signed by the vendor) in the product directories and fails to start, or to present a nag screen that takes a while to disappear, or even to limit functionality.


  1. The product should always tell why the license check failed.
  2. The product never can force the customer to loose work.
  3. The documentation should show failure situations (not just the OK counterparts).

Given some recent posts and the fact that over the course of 10 different versions I lost days of work and at conferences I usually get multiple questions from people having suffered from this, I really had to bring this up again.

Some links and references to IBM CUA: Common User Access which defines a lot of the UIs and UX we still use.

Posted by jpluimers on 2016/02/04

Back in the late 80s and early 90s of last century, engineers Richard E. Berry, Cliff J. Reeves set a standard that still influences the user interfaces and user experience of today: the IBM Common User Access.

I mentioned CUA a few times before, but since an old client of mine managed to throw away their paper originals in a “we don’t need that old stuff any more as we are now all digital” frenzy, I wanted to locate some PDFs. And I promised to write more about CUA.

If anyone has printed versions of the non-PDF documents below, please donate them to aek at or scanning at as they are really hard to get.

A few search queries I used:

The PDFs I think are most interesting:
