Three years ago Gowalla’s journey began when I took a photograph of Lake Tahoe on my iPhone. I had just finished a phone call with my dad, and I wanted nothing more than to share that photo and place with him. Not just in a text message or status update sort of way, but with a bit of weight…

What a Bang!!!!!!!!!!!!!!!

since the starting of 2011 and many claimed that facebook will close on 15-3-2011 and that you have to remove your photos and videos before that date to avoid any data loss . unfortunately Many believed this false claim and some started removing their photos and videos from the website.it didn’t stop till here but others kept sharing this link http://page-facebook-2011.weebly.com/  which says that facebook will be a paid service instead of being free, Commen sense says that if facebook wants to announce this could have announced it on everyone’s homepage as a notification or the Url should look like this http://page-facebook-2011.facebook.com/

Moreover that link is a subdomain for a service called Weebly which is a free tool to create websites online so do you think that the multi billion company will use this service to create this page !!!!!!!!!!!!!!!!!!!

Need a randomly chosen element from an array? There’s a method for that!
Array#choice (Ruby 1.8.7) or Array#sample (Ruby > 1.8.7):

[1,2,3,4,5,6,7,8,9].choice
=> 5

[1,2,3,4,5,6,7,8,9].sample
=> 8
[1,2,3,4,5,6,7,8,9].sample(3)
=> [3,8,9]

during working on a project @ MashLtd , I faced a problem which nearly made me cry :) :), my task was to send XML containing Arabic characters.

the Good news is that Rails sends all XML data in Utf-8 encoding by default but 

The bad news is that Rails converts any non ASCII characters to a format called XMl decimal entity format

so every time you write the following code 

render @object.to_xml 

you find this format showing up 

I searched online but unfortnetly i didn’t find a way to solve this problem

so i had to do it by myself :)

The problem is caused from the gems called Builder as it has a method called escape under XMLBase class this method does the following

 private
  def _escape(text)
    text.to_xs
  end

(dot)to_xs is the method which converts the data to entity format

So all what you have to do is just override the method and remove (dot)to_xs

you have to create a file in the intializers and name it for example patch_for_xml

then add in it the following code

class Builder::XmlBase < BlankSlate
  private
  def _escape(text)
    text
  end
end

this is called monkey patching , it is used to override classes you could use any others if you like

before Rails 3 you had to do the following to escape html 

<%=h @user.name%>

but after Rails 3 the html is escaped by default so if you just wrote

<%= @user.name%>

the html is escaped by it’s own

to unescape html in Rails 3 you have to do the following

<%= @user.name.html_safe%>

Did you know you can pass a number parameter to Array#first and Array#last?

x = [1,2,3,4,5,6,7,8,9,10]

x.first 5 
=> [1,2,3,4,5] 

x.last 2 
=> [9,10]
