Great series of articles, thanks a ton. I'm trying to understand the relation between the following observations: > Maybe, unsurprisingly, the top 5 choice is relatively constant with Python and JavaScript leading the pack and can be a safe choice to learn these days. [...] Surprisingly the drop for Ruby is also noticeable. (part 1) > Ruby on Rails and Django both look as a solid choice for the next startup's stack. On average both lost some audience, but the gap between them and the next thing is really big. From the graphs it also seems that Ruby/Rails has a stronger correlation than Python/Django does. Makes sense, since as far as I can tell there are more non-webdev Python jobs than there are non-webdev Ruby jobs. But it seems that Ruby/Rails is more popular than Python/Django, so although learning Python is better in one sense, learning Ruby/Rails is better in another sense. In other words, if you are looking for a web dev job, you have better chances of finding a job if you learn or have Ruby/Rails experience. But if you are not interested in web dev, Python is the safer choice. (All other things being equal, of course.)
