I sympathize somewhat with your intention. The DotA community is definitely one of the most toxic, rude, immature, and downright racist communities I've ever experienced. Not that everyone, or even a majority of players have these qualities, but the prevalence of these traits is disproportionately high. However, I think the way you've attempted to tackle these problems is not productive for a couple of reasons.

I hope you don't take the following as a personal criticism, but instead as just a comment on how your dialog may be perceived by some others. The other commenters hit several of the major points:

As thewoodenaisle points out, these sorts of posts are emphatically not the sort of thing that people browsing the DotA subreddit are looking for.

As aidrocsid touches on a little bit, the tone with which you present these videos comes across as "standoffish, condescending, completely irrelevant, preachy, and annoying." It feels like you're targeting an attack against people of that community (and maybe you are), and in general people don't respond well to being attacked. Furthermore, such discussion is draped in a culture that many in the DotA community would find alien, and so it makes you like an outsider hurling criticism at the community.

Additionally, you respond to people's comments in a way that is standoffish, melodramatic, sarcastic, and condescending. Again, while these sorts of things may feel good, they're very likely to cause the listener to stop listening and attack back. Frankly, you sound like you've had some bad experiences with the game -- something which I can absolutely sympathize with -- and you've come to pass judgement on the people who might have contributed to those experiences.

I agree in general the community has issues, but I'm not sure what response you expected.

I've been trying to write a more general neural network library as a learning project and this article was very helpful as a concrete test case for exactly the reasons you stated. This is of course coming from someone whose only background in machine learning is watching some videos from a courses course.

Can you expand on what you mean with the regards to painting the gaming community with a broad brush stroke? The abstract doesn't seem to be making overbroad claims, although perhaps the title of the story is overstated. I think hogwild gave a pretty good explanation of the paper's emphasis.

It's of course dangerous to extrapolate from anecdotes but does your personal experience run contrary to this?

According to arstechnica, this incident is being a little overstated.

Courtney Hohne, a Google spokeswoman, e-mailed Ars: "The headline here is that two self-driving cars did what they were supposed to do in an ordinary everyday driving scenario."

It seems that what actually happened is the not uncommon situation where one car tried to change lanes, but the other car merged into that lane first. The only difference here is this involved to self-driving cars instead of cars being driven by humans.

IMAX issued an apology it seems.

I've been using Julia for my research projects since early this year and I've been pretty pleased with it. It's fairly fast without making you do much optimization and the fact that it has a REPL is extremely useful.

I'm a physics graduate student. Largely that means I spend my days trying to find errors in a calculation that is obviously wrong, sitting with my head in my hands trying to figure out how to approximate something that seems impossible to calculate, or trying to figure out why my simulation/numerical code is blowing up. Occasionally things make sense and those are the best days.

I don't really feel like a particularly productive member of society, but all in all I'm pretty happy with my job (disregarding the pay) and I'd be happy if I can keep working in the field.
