Clayton Christensen has died

Clayton Christensen died on Jan 23, 2020 at the age of 67.

You may know him from his 1997 best selling book, “The Innovator’s Dilemma: When New Technologies Cause Great Firms to Fail.”

He was incredibly influential, well beyond the typical author.

Any vendor that thinks automated installation is a new concept… sigh.

So what does that have to do with Chocolately?

(Existing certificates will remain valid for their full term).

The Slightly Broken Door Problem

When I worked at Bell Labs, there was a door that slammed really loudly when it closed. This wouldn’t be a big deal except that it was right near me. Oh, and it was in the middle of my team’s offices so when it slammed, nearly everyone on the team would jump.

Fax Machines Arent Magic

I can’t believe my health insurance makes me fax certain forms. What year is this?

Well, anyway… that reminds me of something that happened to me many years ago back when fax machines were more common.
