Working with Rails for some time you start nitpicking on how to improve it. This is a first in the series of articles regarding on how to improve (even marginally) Rails's performance.
I'll focus on a bunch of gems that speed up, in some cases considerably, small parts of Rails, like the html escaping, the String#bla ...

Ruby 2.1 was released this Christmas, great news everyone! It sports a better GC (RGenGC - gerational GC), hierarchical method caching, some small syntax changes and non-experimental rafinements. All in all one can expect 5% to 15% performance increase which is quite awesome.

Another interesting difference is in the implementations:

We all know that for a rather large Rails app where the front-end is quite stuffed, the asset pre-compilation and more importantly - development mode changes are far from instantaneous.
The front-end we're referring to is the kind that makes heavy use of sass, sass libraries (Compass, Bourbon, etc.) and transpiled Ja ...

I like to use Rollbar 's default plan for small apps or prototypes that are wip. Getting production exceptions in my inbox can be quite useful but most of them are actually 404s - sure there are a multitude of ways for filtering out the noise ([Fail2Ban](https://www.digitalocean.com/community/tutori ...
