To solve this issue, move to the zlib/ folder, it should be something like this /usr/src/ruby-1.8.6-pXXX/ext/zlib/

execute the extconf.rb :

1

root@xen1:/usr/src/ruby-1.8.6-p398/ext/zlib# ruby extconf.rb

If every things are ok, you should see:

1
2
3
4

checking for deflateReset() in -lz... yes
checking for zlib.h... yes
checking for kind of operating system... Unix
creating Makefile

compile and deploy zlib by runnning both commands:

1
2

sudo make 
sudo make install

Make sure gem command is woking:

1

gem list

You should see:

Gtalk

  • to make it bold, simply use * * (asterisk) between the text that intended to be bold in font style : i.e. *marouan* is rendred as marouan.
  • to make it italic, simply use _ _ (underscore) between the text that intended to be italic in font style: i.e. _marouan_ is rendred as marouan.
  • to make it strikethrough, simply use – - (dash) between the text that intended to be strikethrough in font style: i.e. -marouan- is rendred as marouan.

This is a stupid post but if you are addicted to Google Talk, like me, you will have more fun with GTalk using those few styling tips.

Unfortunately iTextSharp, which is an open source java library for PDF generation written entirely in C# for the .NET platform, do not allow to print special chars (é, è, ç …etc.) properly.

Happily, I found this very useful piece of code in the Internet and I want to share it with you:

[ad#only_in_post]

You want to use an image as a link.However, a blue border appears around the image.

<a href="http://www.myownpercept.com/">  
  <img src="logo.png" alt="" />
</a>

This border is meant to inform users that the image is a link. Well, it’s a link but this is ugly :s and may not fit your need.
[ad#hire_me]

Solution

  1. You simply have to add a border-style, set to none, as a style to your img tag 
    1

3

    <a href="http://www.myownpercept.com/">
  <img style="border-style: none;" src="logo.png" alt="" />
</a>
  2. A cleaner way, that will pass the W3C validation, is by adding those lines to your CSS file : 
    1

3

    img {
	border-style: none;
}
  3. A dirty old way, but works, is by adding border attribute to the img tag.
