The Handbook taught me an enormous amount - more than many of my university courses - including things that had nothing to do with FreeBSD specifically. It taught me the right approach: understand first, act second. The more I read, the more I wanted a printed copy to keep at my desk. So I convinced my parents that I needed a laser printer “for university work”. And the first thing I printed, of course, was the Handbook. That Handbook still contains relevant information today. There have been significant changes over the past twenty-four years, but the foundations are still the same. Many tools still work exactly as they did. Features have been added, but the originals still operate on the same principles. Evolution, not revolution. And when you're building something meant to last, that is - in my view - exactly the right philosophy. Change is good. Innovation is good. On my own machines I've broken and rebuilt things thousands of times. But production environments must be stable and predictable. That, still today, is one of the qualities I value most in every BSD.
