I post my normalization function. This function find all illegal characters (like: Ő, Ű, ú, í, etc. ) and replace it to latin1 chars. (like: O, U, u, i, etc.) This function works for me on hungarian words. Try it on your text and post your comment about it.

function normalize($string) {
    $string = strtr($string, array('ő' => 'o', 'ű' => 'u', 'Ő' => 'O', 'Ű' => 'U'));
    $a = 'ÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖŐØÙÚÛÜŰÝÞßàáâãäåæçèéêëìíîïðñòóôõöőøùúûűüýýþÿŔŕ';

Here is an example, what show the way you can translate your mongoid models:
You can also customize error messages as you will see in the next example.

User model translation Example:
en.yml content:

en:
  mongoid:
    errors:
      models:
        user:
          attributes:
            email:
              blank: "You have to give me your e-mail address"
              not_found: "e-mail address not found in list of members"
              #...
    attributes:
      user:
        email: "Email address"
        name: "Your nickname"
        #...

I got the following error when i run a rake db:seed command on may RoR application:
invalid multibyte char (US-ASCII)

I found the soution and the error has gone away:
You should add a line to your file:

# encoding: utf-8

You can change the utf-8 to any other encoding that you use.
I added this line to my seeds.rb file and all UTF-8 code have been executed without errors.

Good luck!

Some useful git command with branches and remote repositories.

Remote operations

List remotes:

git remote -v

Add remote gitosis server:

git remote add <remote_name> git@myhostname.com:my_project_name.git
git push <remote_name> master

Where master is your branch name

Main git branch orperations

list branches:

git branch -v

-v is optional, you use it to get more verbose output

Create new branch:

git checkout -b <new_branch_name>

I've collected all open source CMS based on rails 3.x.

Rails CMS/Wiki/Forum

This is a very simple but feature rich CMS framework. It is good startpoint for a new rails project what will be wiki, Forum or CMS

Source: https://github.com/jlapier/Rails-CMS-Wiki-Forum

Casein CMS

This is a very minimal and lightweight CMS. Only users table created on rak db:migrate. It is a good start point for any content based application. This application scaffolding your rails app with a very beauty user interface.

function foo($year = date('Y')) {
  // this is invalid
}

So, how should do it?

define('THIS_YEAR', date('Y'));
function bar($year = THIS_YEAR) {
  // this is valid
}
