linkto gem - link_to helpers for google search, flickr photo search, wikipedia search, and more prost.herokuapp.com
Hello, I've collected a couple of link_to helpers in the new linkto gem. Helpers include:
google_search, google_search_images, bing_search, flickr_tags, flickr_search, wikipedia_search, and so on. See the linkto gem in action at the beer.db.admin site, for example, see the Ottakringer brewery page. Cheers.I just launched gem rails-cache_control which can significantly speed up your page. This gem will automatically add HTTP Cache-control header when caches_action expires_in specified. You do not need write a single line but just included it in Gemfile.
Rails: Be careful with params.merge() blog.bmonkeys.net
I've seen a lot of people doing it and I used to do it too, use params.merge(…) in link_to or redirect_to calls. You do this because you want to change one ore more parameters (like the locale, current page or search query) but leave the rest as it is. But heads up, there is an issue with this solution!

Back to Basics: Polymorphism and Ruby robots.thoughtbot.com
Polymorphism is one of the fundamental features of object oriented programming, but what exactly does it mean? At its core, in Ruby, it means being able to send the same message to different objects and get different results. Let's look at a few different ways to achieve this in Back to Basics: Polymorphism and Ruby.

The "don't use a small gem" fallacy mauricio.github.io
Much is said about code reuse, when to reuse and how to reuse, but there's a strong movement about not depending on a gem if it's small or if you can write one that does the same yourself. Is it really an improvement to write one yourself?

The GC in Ruby 2.1: understand it, see it at work and tune it thorstenball.com

Memory used above quota will swap out to disk, which substantially degrades dyno performance.
If the memory size of your dyno keeps growing until it reaches five times its quota (for a 1X dyno, 512MB x 5 = 2.5GB), the dyno manager will restart your dyno with an R15 error.
You don't want "SUBSTANTIALLY DEGRADED PERFORMANCE" do you? Of course not.
Whacamole will help you monitor and restart your dynos yourself.
I've made a new gem called Mock5 that allows to easily create remote API mocks using Sinatra and plug/unplug them at will. Using it, you can test all kind of situations, like API being down or taking too long to respond, responding successfully or with authentication error.
