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:

| 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`
I met the following error when trying to launch an Android project using eclipse:
[2010-10-23 19:31:02 - adb]Failed to get the adb version: Cannot run program "/usr/src/android-sdk-linux_x86/tools/adb": java.io.IOException: error=2, <a href="http://www.score-louisville.org/content/view/31/">cialis effectiveness</a> No such file or directory
After googling I found those useful steps to make it running properly:
1. install getlibs from http://frozenfox.freehostia.com/cappy/getlibs-all.deb
2. open terminal and go to your android folder and then platforms/android-1.6/tools
3. run this command from terminal getlibs aapt

Copy and paste the following commands into your terminal:

| sudo add-apt-repository "deb http://archive.canonical.com/ lucid partner"
sudo apt-get update
sudo apt-get install sun-java6-jre sun-java6-jdk sun-java6-plugin sun-java6-fonts |
Verify your java version:

The Juggernaut plugin for Ruby on Rails aims to revolutionize your Rails app by letting the server initiate a connection and push data to the client. In other words your app can have a real time connection to the server with the advantage of instant updates. Although the obvious use of this is for chat, the most exciting prospect is collaborative cms and wikis.

Today I got the error below :
1
| ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO) |
after typing :
I don’t know why ? but I know how to solve it.
First of all let’s disable password authentication :
Stop your MySQL daemon:
or
1
| /etc/init.d/mysqld stop |
Then run the following command line in background :
1
| mysqld_safe --skip-grant-tables & |
Secondly run :
Finally, In your MySQL command line prompt issue the following command:
1
2
3
4
| USE mysql;
UPDATE user SET password=PASSWORD("my_password") WHERE user="root";
FLUSH PRIVILEGES;
EXIT |
Password is now reset to my_password. So just restart your MySQL server using :
1
| /etc/init.d/mysql restart |
or
1
| /etc/init.d/mysqld restart |
and use your new password to authenticate :
All that remains is to enter your password.
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.
