In the previous post Almi wrote about problems with Java what predicted not too much that technology. With this thought beside iPhone and Android frameworks we open our field of interest to new Web development MVC frameworks what is simple, supported and if it is possible more agile then Java development. Till now I prefer PHP/Zend Framework pair because I already use PHP before but for alternative solution there is Ruby On Rails. Today I tried to develop a small “Hello World” application with Rails and I collected pitfalls of it.
