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:
You should see:
Just move to the directory where you want to delete, recursively, the .svn directories and type the folowing line:
rm -rf `find . -type d -name .svn`
To have more fun with GTalk (Google Talk) you can add some text formatting :
- 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.
I have been working on a c# french desktop application. 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:

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.

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

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

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

I am sharing here my Erlang Cheat Sheet after some lifting 
in order to make it more useful.
Certainly, it’s not an exhaustive list of Erlang commands.
I hope you will find it useful.
ps : If there is a mistake. Please report it and I will be very thankful.

Suggestions / things to be added ? are very welcome.
