Thanks to José Valim we have a nice new plugin for better debugging of Rails applications! In his blog post he describes how to open links to files on your hard disk with notepad++ on windows. I adapted this idea for opening files with netbeans on linux, and here is your way to go:

open about:config in firefox and add:

• string network.protocol-handler.app.editor with content ~/.editor.rb
• bool network.protocol-handler.external.editor and set it to true

create the file ~/.editor.rb and make it executable:

touch ~/.editor.rb && chmod +x  ~/.editor.rb

And here is the content:

#!/usr/bin/ruby
file = ARGV.first.split('file://').last.split('&').first
line = /\&line\=(\d+)/.match(ARGV.first)[1] rescue 0
`"/path/to/your/netbeans-dir/bin/netbeans" "#{file}:#{line}"`
`wmctrl -a "NetBeans IDE"`

install wmctrl

sudo aptitude install wmctrl

We’ll need this to give focus to the NetBeans window.

class String
  def to_money
    fee = self.match(/(\d+)(,|.?)(\d{0,2})/)
    if %w(, .).include?(fee[2]) # 56,99 1.00 5,-
      return "#{fee[1]}#{fee[3].to_i.to_s.ljust(2, '0')}"
    elsif fee[1] && fee[2].blank? # 5
      return "#{fee[1]}00"
    end
  end

  def to_money!
    self.replace to_money
  end
end

Now you can do some fancy stuff like the following:

"12 Euro".to_money => 1200
"12 Dollar".to_money => 1200
"12.00 Dollar".to_money => 1200
"12,00 Euro".to_money => 1200
"12,- Euro".to_money => 1200
"1200 Euro".to_money => 120000
money = "12,8 Euro"
money.to_money!
puts money # => 1280

You can read about the motivation why to use integer in favor of decimals in the database here: 7 Top Tips for Coding With Currency.

[hans@zommuntu:~]$ time ssh user@production_server "mysqldump --add-drop-table database_to_process -uUSER -pPASSWORD | gzip" | gunzip | mysql -uLOCALUSER -pLOCALPASSWORD database_name
real    0m4.389s
user    0m0.592s
sys     0m0.052s

Under five seconds! woot!!
Some words to explain this: First, you establish a ssh connection to the production_server. The gzipped dumped sql of the beloved database_to_process is transferred to your machine. Here it is gunzipped and written to your local database server into the database_name. The quotes are necessary as brackets to let the script know that the gzip command belongs to the ssh command.

require 'net/http'
require 'iconv'
require 'uri'

arg = URI.escape(Iconv.new('ISO-8859-15', 'UTF-8').iconv(ARGV[0]))
str = Net::HTTP.new('www.google.com', 80).get("/translate_t?text=" + arg + "&langpair=de|en").body.match(/id\=result_box\ dir\="ltr">(\S*)<\/div>/)
if str
  puts Iconv.new('UTF-8', 'ISO-8859-15').iconv(str[1])
else
  puts "error.."
end

Of course you can change the languages! Just edit the langpair=de|en at your will. Be sure to have ruby installed!
