Those spikes are curious, so let&#x27;s add a couple of other languages:<p><a href="http:&#x2F;&#x2F;www.indeed.com&#x2F;jobtrends&#x2F;q-rails-q-ruby-q-javascript-q-php.html?relative=1" rel="nofollow">http:&#x2F;&#x2F;www.indeed.com&#x2F;jobtrends&#x2F;q-rails-q-ruby-q-javascript-...</a><p>Seems like this is likely to reflect something other than changes in language popularity. Frankly the data doesn&#x27;t seem very interesting without correcting for other factors such as total volume of jobs.<p>Overall, Ruby looks pretty much as popular today as 3 years ago to me from that data, though perhaps with Rails in a downwards trend (awesome - I love Ruby, but finding Ruby work that doesn&#x27;t imply Rails is harder, and I don&#x27;t like Rails).<p>But it&#x27;s besides the point anyway. I simply explained why someone mentioned Rack, I don&#x27;t particularly care either way (probably because I don&#x27;t really care about Convox Rack - I&#x27;d never use a single vendor solution like this, and haven&#x27;t exactly hidden how overpriced I find AWS in past comments).
