Articles plagued with stuff like "this is horrible", "this is shit" and so on and son.
I see too often articles that just try to denigrate other technologies, saying that they suck, they are horrible, they are shit, they should be considered harmful, etc, just to try to make the author sound smart-assed.
The truth is that most stuff is the way it is for a reason. Maybe the situation has evolved and the reason is no longer valid, or maybe the people that built the thing had different goals than you. But understanding why it was valid for the other person and why it is maybe not valid for your use-case in an empathetic way will only make you a better engineer. We are all smart people trying our best to achieve something using technology. We are on the same boat. Let's stop insulting each-other.
If I was a novice and saw and article like this, I don't think I would want to hang out with such an overreacting crowd. Python is a libre project: instead of insulting other people's work to sell your book, try improving it. I can understand why proprietary software sometimes sucks -- it is disempowering -- but with libre software you are just kindly given a gift. If you don't like it, improve it and give back to the community, don't denigrate.
