Don't know if the concept of DevOps is bs but I know that it's unfortunate if a developer never did system administration: there are many of this "git push heroku" kind of devs who pee in their pants if they have to deal with bare metal and the production servers. It's not that they wouldn't be able too handle them, it's that they are afraid because they never did and besides, good system administration knowledge leads always to better application and system design.
Dogmatic thinking is never good. I've been on many conferences and many could been perceived as wasted time. And on one which was one of the worst I met tons of 'useless' people and by accident one guy who invested in me $4M.
So you never know who will be 'useless' and on conferences you meet so many people in a very short time, that it's ultra efficient. And you get appointments easier because meetings can be quicker.
However, most important with any conference is that you try to get at least 5-10 appointments for a conference which means you have to reach out to min 50
Many folks in this thread are expressing that it's the OP's fault and not Ruby's.
The OP made his post as objective as possible, politely written and nobody is loosing his face, neither Ruby as a language nor the Ruby community. But people are still resentful and fire back.
I believe it's not a discussion about Ruby anymore, its strengths, its weaknesses and wether Ruby still fits in 2015—no it's the fear of people that their core competence might be less worth in future. That all the time and energy they invested all the years into one language might be not a good investment anymore. The fear that better tech will replace their tech and that they have to start at zero again.
I know I am going to be heavily downvoted for this post. Before you downvote just think a second again why you'll downvote me.
A while ago after I installed uTorrent all my browsers (Chrome, Firefox and Safari) switched to Yahoo as my default search. Then I changed them back to Google.
After a while (I guess after I rebooted the computer) again all browsers showed Yahoo again. I googled for some help I found a hint that I have to disable and remove the 'Searchme' extension. I did so.
After a while (I guess after I rebooted the computer) again all browsers showed Yahoo again and the Searchme extension showed up again. And still Searchme is there—I took a screenshot http://imgur.com/OsH9o0m
