Like many of you, I played with Legos as a kid, and decided to bring up LeoCAD, which is the FOSS version of Lego Digital Designer (and should be in most repositories). Although it's not as feature-rich as LDD, it's still a fun game to play if you don't have any assorted Legos on hand, or if you don't want to spend an arm and a leg.
It seems as Linux becomes more popular, sites like this one start attracting trolls and other weirdos. A common theme I've noticed with this crowd is their profiles have very little information about them, they'll often post threads about them wanting to engage in very shady behavior (or, in one case, be an attention-seeking idiot), and they're only on here for an extremely short while (often a few hours at best).
My dad never fails at showing me how much of an idiot he's become. Even though I'm more than willing to show him how to use the gps app on his phone, he's insists on using a regular gps instead. However, he was perfectly fine with my brother showing him how to use the iPhone he had years ago. There would be a lot less arguments between us if he would simply think, and stop playing favoritism.
