While you're on fourmilab site, I recommend The Autodesk File ebook:<p><a href="https://www.fourmilab.ch/autofile/" rel="nofollow">https://www.fourmilab.ch/autofile/</a><p>A story about how Autodesk started. If I recall correctly (read it 15+ years ago), a bunch of programmers got together, without clear idea what they'll build. So they started multiple projects and decided to focus on what gets the most traction. In essence a way to test multiple ideas in paralel, thus increasing their collective chances.
