It’s 11:43pm on a Monday night. My 6-week-old son is asleep in my office so my wife can get some uninterrupted rest for the first half of the night. He’s finally asleep now, and I probably should be also after a full day of work. But I’m not done for the day. Even though I’m a software engineer by trade, I’m also a computer programmer by hobby and passion. So I do what I’ve been doing for well over a decade now: I boot up my computer to write some code.
What someone does for a living is really none of anyone’s business.
Unless you develop FOSS, in which case clearly random entitled removed on the internet get to tell you what to do with your time and what it is worth, judging by these comments.
