…gives you a clear vision of how performant they are. When you know the number of requests sent for ‘ Request A', you'll be able to tell how much time is spent in each request.
Welcome to the Real World
I'd like to show you some improvements we've made in our iOS API and to our iOS app thanks to New Relic for Mobile Apps.
Track the HTTP Errors
A few weeks ago, we saw that the number of 403 errors was high. So we started to investigate it with New Relic for …

…of a real world application and not just a testing scenario. Maybe we want to take our monolithic Request class and instead run our requests over some HTTP-like protocol over UDP, or maybe even a serial port. If calling Net:: HTTP.new is buried somewhere in an internal # send method, there's not much we can do without DI. We can monkeypatch or redefine methods directly on an instance, but these are not thread-safe or elegant solutions to the problem. DI is the elegant solution, …

The 400 Bad Request status indicates that the request ‘could not be understood by the server due to malformed syntax'. See the IETF docs
There is also the 422 Unprocessable Entity status code that appears to be popular for roughly the same purpose. I've read from a couple of sources that since the 422 is part of the WebDAV extension that 400 is preferable over 422. I don't have the knowledge to weigh in on this argument. Perhaps someone can enlighten …

Looks like there's some focus on ActiveRecord optimizations currently. That's work that many people will welcome.
DHH's routing concerns plugin gets merged to the main line at 0dd24728b - documentation is at 0bd7b07d . This lets you tidy up your routes.rb file by declaring common reusable resources.
0d0d4622 adds Request#formats=(extensions) to let you set a prioritized list of multiple formats to use in response.

…Single Responsibility Principle for me. I'd prefer a pattern where I had a separate Request class for each action, rather than a few largely unrelated methods on the same controller class. But Rails is there and there's a lot else to like, so let's not get into that.
We all know it's a bad idea to let our controllers bloat and something I've been enjoying greatly lately is Jose Valim ‘s Inherited Resources . By sticking to this pattern, …
