Over the course of my career, I've gone from deploying via scp, to svn-up/git-pull, to every variety of actual deployment pipeline imaginable with dedicated dev-ops teams. Now I'm the only engineer at a tiny 501(c)(3), git-pull straight from production again, and have never felt more free.
Asynchronous event loops aren't a core part of the JavaScript: They're from the DOM API and Node standard library. Though it is significant that nothing comparable exists for Python that has reached the same robustness and support.
Why is it that Python's single-threadedness is always singled out over every other language in the general family? Ruby, PHP, Perl, and JS are all single-threaded (Perl ithreads and JRuby/Jython caveats notwithstanding). Celery itself is just a framework for fork management, something that has been available to these languages since their inception.
To those commenting with some variation of "only informed citizens should vote," pause and consider how much overlap there is with your idea of what an "informed" voter is with race/class lines. You may be unwittingly (or wittingly in some cases?) insisting that voters in the US should be, disproportionately, wealthier whites.
