Peter J. Jones, the creator of Vagrant, brings us “Effective Ruby : 48 Specific Ways To Write Better Ruby”. A book geared towards ruby programmers that are already familiar with the structure and syntax, but are looking to get more out of the language. The books covers a wide range of topics, with surprising amount of depth. The chapters are divided into small ‘items’ that can be consumed individually and stand (mostly) on their own. Each offers practical tidbits that can be applied to your own code immediately. I read the book cover-to-cover, but I it would also be suited to jumping around from item to item.
Great article on DHH’s RailsConf 2014 keynote. Even though you can have a badly designed system with tests, let’s not throw out the baby with the bath water.
Jon Yurek writes a thoughful opinion about the use of style-guides. It’s not about the pendantry of the use of curly braces or spaces, but about working as a team, better communications and focus on the important things in the code.
Great tale about finding a great win by running benchmarks, the power of open-source collaboration. One small pull request will benefit thousands of rails apps in the future :)
The Unix philosophy is to build small things and connect them together. How small? That is the crux of the matter. In this post, Avdi shows why sometimes using slightly larger tools, correctly abstracted away can yield better results than roll-your-own simpler alternatives.
Recently I found myself doing pretty interesting things with relational databases that are way, way above what
ActiveRecordallows you to do (even if I where to condone the use of SQL fragments like
Person.order('YOUR_FIELD DESC'), which I don’t). Arel, which powers
ActiveRecordis very powerful for that sort of thing, if a little under-documented. The post by Jiří Pospíšil helped out a lot.
In the post (also a talk), Zach Holman describes how Github continues to innovate and add features to their product, without breaking existing functionality. This post is interesting at the technical level, but also covers how the do team and company structure and communication in a way that doesn’t weight them down. Highly recommended.
Short post on using the Null Object Pattern. Polymorphism for the win!
Leslie Ekas and Scott Will present a practical approach to Agile that balances the philosophy of the Agile Manifesto with the tools and techniques needed to navigate the roadblocks that those wishing to implement Agile encounter on a daily basis.
There is a well-known idiom in Rails, to tell wheather one is runnign in a specifc environment or not:
