This article was originally written for the [12 Devs of Summer](http://12devs.co.uk) and posted [here](http://12devs.co.uk/articles/writing-a-web-application-with-ruby-on-rails/). It was written for beginners, I described how to get up and running withRuby and Rails and I tried to offer an in depth look at what it’s like to work with it. In this tutorial, you'll create a simple _non Hello World_ application.
During the last months, I was looking for a new programming language to learn for _fun and profit_. I picked [Go lang](http://golang.org), then I tried to build something enough complete and/or useful, to see how it feels to program in Go with an everyday task. Here's how it went.
Maybe you already know and used the Ruby's [OpenStruct](http://www.ruby-doc.org/stdlib-2.0/libdoc/ostruct/rdoc/OpenStruct.html) class. I've played a bit with it to create a very easy to use configuration system for Ruby apps.
Rails 4 will use [StrongParameters](http://rubysource.com/rails-4-quick-look-strong-parameters/) by default. However, it doesn't seem that Devise is ready for this feature, even using its [rails4 branch](https://github.com/plataformatec/devise/tree/rails4). There's a [good example](https://gist.github.com/kazpsp/3350730) that explains how to solve this problem when dealing with only one resource (eg: `User`). I forked that code to handle more resources (eg: `User` and `Admin`) without repetitions.
A basic example to show how to implement simple/clean jQuery plugin with CoffeeScript.
When I purchased an [amazon kindle](https://kindle.amazon.com/), some people started to ask about how's going with it and if it's worth to buy one. I decided to write a review only after the first battery recharge, just to be quite sure I've used it enough. This happened after three weeks, so here's my thoughts.
Uploading images with custom sizes on different models is a very common task during web development. Every time, people uses different image uploaders for each model, where the only difference is about sizes. I'd like to share a simple hack to DRY code with some metaprogramming.
It was exactly one year ago, when I launched for the first time http://andreapavoni.com. Now I'm here with a shiny new website, powered with a custom blog engine and some stuff to show off :)
When it comes to develop a CMS, one of the main problems concerns where or how to store and organize views (templates, partials, layouts) for particular needs like different layouts for specific pages, (sub)domains or multi-languages.
In the [last post](/blog/rails3-using-arel-to-make-conditional-searches-based-on-conditional-params), I explained how to make conditional searches based on conditional params. I wrote a very simple Search class that returns a real model with query done by Arel. I refactored the code to make it simpler to use.
I needed simple searching on some models, and I didn’t want to use any plugin for this task, just because I’d like to try the new rails3 features, like ActiveRelation (Arel).
