Yes, my nickname is derived from the Microsoft Corporation. To explain why, I have to start with the CD "Truhla Járy Cimrmana" (Jára Cimrman's chest) which came out in the Czech Republic several years ago. You can find more about this fictional Czech genius in his Wikipedia article.
The disk was mentioned in Lidové noviny (a Czech newspaper) which recounted the CD's claims: Cimrman is also credited with invention of the CD (and that the abbreviation actually means "Cimrman's disk"). Unfortunately, he manufactured them using wood and wax, which made them not very durable. "Later, Mic Rosoft took hold of this invention ..." (Microsoft was a producer of this CD.)
And this is where my nickname came into existence.
