That&#x27;s a great article!  Bookmarking.<p>But, what does ANY of this have to do with me?  I learned to avoid (well, mostly avoid :-) the &quot;well actually&quot; trap almost two decades ago and have spent the intervening twenty years mentoring younger engineers out of that habit.<p>What I was actually responding to was the idea it was better to &quot;speculate&quot; about who played Snape, or why is the sky blue, or is vim BSD or GPL licensed rather than look it up.<p>I&#x27;d rather have conversations about Alan Rickman portrayal of Snape or what impact the sky being blue has on our emotional reactions to blue or why vim is clearly better than emacs.<p>Also, Canadians, in general, don&#x27;t tend to discuss politics in that manner, at least not in mixed company.  We have more political parties and our views are more fluid. I have, for example, voted for 4 different political parties in my life time at the federal level alone.
