When I started working at Microsoft a few years ago, one of the first things I did was create a OneNote file to keep track of everything. I had to learn about internal procedures and tooling, partners, projects, and so many other things. The hierarchical nature of OneNote files made it easy to arrange this loosely related information into a well-organized set of documentation that I could quickly refer to. When I left Microsoft to take a job at Red Hat, I wanted to keep using the concept, but with an open source tool.

May the fourth be with you: How Star Wars (and Star Trek) inspired real life tech

sam, 05/04/2019 - 09:01

Conventional wisdom says you can either be a fan of Star Trek or of Star Wars, but mixing the two is like mixing matter and anti-matter.
