In the olden days, I was a project manager at a string of Seattle-based start-ups. One of the worst parts of my job was dealing with people who trained mostly on Microsoft products; they simply couldn't wrap their heads around the fact that an increasing number of people just don't use Windows-based servers.
And I'm not the only one with this problem. Today I found this trailer for a mock movie called "Java 4-ever," about a young man who comes out to his .Net-obsessed father as a closet Java user. It's out of Norway and stars the likes of "William Windows," "Mona Lisa Harddrive," and "Lenny Linux."
Now, Java's not my favorite development platform (PHP all the way, players!), but I've used it and it works. Chances are you've used it and never even known it. But the point is that sometimes grown-ups just need to be platform-independent, with parental approval or not.
Also, I wish this was a real movie. (Note: a quick NSFW image appears toward the end of the vid.)
