programming

I've read ti in stackoverflow:

E.g. to remove all *.gz files accidentally committed into git repository:

$ du -sh .git ==> e.g. 100M
$ git filter-branch --index-filter 'git rm --cached --ignore-unmatch *.gz' HEAD
$ git push origin master --force
$ rm -rf .git/refs/original/
$ git reflog expire --expire=now --all
$ git gc --prune=now
$ git gc --aggressive --prune=now

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';

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
}

Here is my HTML number formatter. Sometimes the browsers wrap the numbers along thousand separator or decimal pont, but this function prevents this event.

function html_number_format($number, $decimals = 2, $dec_point = '.', $thousands_sep = ',') {
  if ($number === FALSE) {
    return '---';
  }
  return '<span style="white-space: nowrap;">'.number_format($number, $decimals, $dec_point, $thousands_sep).'</span>';
}

See the following code:

<div style="background-color: #fff; border: 1px solid #000;">
<OBJECT CLASSID="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" WIDTH="214" HEIGHT="200" CODEBASE="http://active.macromedia.com/flash5/cabs/swflash.cab#version=5,0,0,0">
