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

Creating init.d script for Juggernaut
July 24th, 2010
No comments
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.

ERROR 1045 (28000): Access denied for user ‘root’@'localhost’ (using password: NO)
July 27th, 2009
4 comments
Today I got the error below :
1 | ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO) |
after typing :
1 | mysql -u root |
I don’t know why ? but I know how to solve it.
First of all let’s disable password authentication :
Stop your MySQL daemon:
1 | /etc/init.d/mysql stop |
or
1 | /etc/init.d/mysqld stop |
Then run the following command line in background :
1 | mysqld_safe --skip-grant-tables & |
Secondly run :
1 | mysql -u root |
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 :
1 | mysql -u root -p |
All that remains is to enter your password.
GTalk: Text Formatting; bold, italic and strikethrough.
July 21st, 2009
2 comments
To have more fun with GTalk (Google Talk) you can add some text formatting :
[ad#only_in_post]
- 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.

Q : What’s the best thing that may happen to a developer ?
A : A Bug
I ran script/console in a rails project to debug something on console, but I got this LoadError:

How to fix ?
I figured out that some libraries are missing after installing ruby from sources (I got those troubles after upgrading my ubuntu from 8.10 to 9.04 and then reinstalling ruby from sources to solve a non-compatibility problem of the already installed ruby binary package with ubuntu 9.04) :
1 2 | sudo apt-get install libncurses5-dev sudo apt-get install libreadline5-dev |
Then move to your ruby source folder, subfolder ext/readline and then configure, build and install stuffs.
[ad#hire_me]
1 2 3 4 | cd /usr/src/ruby-1.8.6-p368/ext/readline/ ruby extconf.rb sudo make sudo make install |
you may get something like this : ( when running ruby extconf.rb)
