Wow! Well written and amazing inside inside Unicorn. Recently I was reading the internals too when doing worker prewarming. Check it out https://github.com/3scale/unicorn-prewarm

This got me thinking. Would it make sense to prewarm the app in the master? I think it is safer in the workers, but still.

A similar overview. Might be interesting too http://tomayko.com/writings/unicorn-is-unix

This is a great post with many informative asides about the in's and outs of Unix. As a guy who can't stop looking under the hood myself, I found this to be a very palatable introduction to a lot of things I previously found to be complex. Great stuff!

Need a similar article about uWSGI. Way more interesting and complexity than Unicorn.

Thanks! I fixed the link.

Thank you for making the awesome content! Watching now :)

Isn't this magic master-worker architecture just what we called pre-forking with Apache in 1998?
