"tl;dr: if you want to do web development but dislike Rails, your best bet is probably to switch to a different programming language than Ruby."
But... wasn't this the underlying point of Solnic's opinion piece?
Due to Rails "well deserved" domination in the web framework space, POROs never had a chance of contributing to friendly and just competition across the Ruby community. We simply ended up with shitty alternatives because no one was given the proper chance to be BETTER Rubyists.
They just kept eating the gluten and feeling the allergy pains, so to speak.
I concur. Coming from São Paulo, Brazil, I thought Akita's post was well written and derived out of positive, lightly spoken, opinion. Breath of fresh air against the backdrop of hostile tech machoism.
I completely agree, moving the port is a must just to change up the configuration from everyone else's. Configuration items like port numbers are meant to be tweaked, especially when you can just stick a unique SSH port in your ssh_config.
However, it's not hard to imagine these scanners have moved further past the days of the Morris worm and aren't just simple port scanners. Identifying what services are on what ports is a relatively easy process that doesn't remove much from the discovery phase of a bot or script kiddie. Hell, code review metasploit for a half hour and rip theirs out.
