Just ran into this poll (https://news.ycombinator.com/item?id=750142) that was made 5 years ago. And I am very interested to see if anything has been changed.
We have Ruby, Python, Go, C, Node, Perl, Backbone and maybe a few others I'm not remembering right now.<p>When you're building distributed systems, you pick the right tool for the job.<p>Edit: And Assembly: <a href="http://youtu.be/zrSvoQz1GOs?t=15m44s" rel="nofollow">http://youtu.be/zrSvoQz1GOs?t=15m44s</a> I'd actually recommend the entire talk.
No iOS or Android? I would have thought the biggest change in the last five years (since you last conducted the survey) would have been the massive increase in startups working in mobile.
We use R and Shiny server pro for our back-end. It's hosted on AWS EB with our static site on S3. We love it - the data scientists can write and push features directly, and everything (including our API's) are easily maintainable in R. I've been shouting the praise of R and it's usefulness as a production ready language for a long time.<p>Contact me with questions about data science, start ups, or R - if you have a data backed start up, R + Shiny is the way to go.
Erlang with the Nitrogen Web Framework (<a href="http://nitrogenproject.com" rel="nofollow">http://nitrogenproject.com</a>)<p>Also, a future project I've been kicking around will likely be done with Erlang and ChicagoBoss (<a href="http://chicagoboss.org" rel="nofollow">http://chicagoboss.org</a>) - not because Nitrogen is lacking, just in the name of mastering another framework with a different focus.
Ruby + Grape / Polymer + CoffeeScript on the frontend with MySQL, MongoDB and Carbon as databases, using RabbitMQ to hook it all up. Right tool for the job with some legacy. There's an old school Rails project and some Python as well.<p>We use docker to make provisioning on Linux development machines less painful, vagrant/Capistrano + chef for the ops.
At work I've been working primarily with Ruby on Rails, but for personal projects and my fledgling startup, I'm using Django with Ember.js in the frontend.
Nice to see some Django. I had to move away from it and towards flask and rails since it was basically abandonware for years. I'm glad they are moving forward and that the project is hosted on GitHub now.
