/etc/init.d/mysql stop
mysqld_safe --skip-grant-tables &
mysql -u root

Step 2 - At the mysql shell set the root password and flush privileges.

USE mysql;
UPDATE user SET password=PASSWORD("new-password-here") WHERE User='root';
FLUSH PRIVILEGES;
QUIT;

Step 3 - Back at the linux shell stop the mysqld_safe process and start the normal mysqld process. At this point you should be able to successfully login as root using the password from Step 2.

/etc/init.d/mysql stop
/etc/init.d/mysql start
mysql -u root -p

The last few years I’ve been using both with NewsGator Online to read and sync my news feeds daily. I’ve found this to be the perfect combo, allowing me to move from one machine to the other without seeing the same news item twice.

Earlier this week it was announced that both FeedDemon and NetNewsWire would be available for FREE (previously $30 each). If you’ve been looking for a commercial quality RSS feed reader then I highly recommend you give these a shot!

( expr1 ) ? ( expr2 ) : ( expr3 )

Take the following code for example where we determine how to greet a user.

<?php
    if(isset($user)) {
        echo $user->name;
    } else {
        echo "Guest";
    }
?>

The code above is simple enough but let’s see how we can improve it by refactoring using a ternary operator.

<?php echo (isset($user)) ? $user->name : "Guest"; ?>

Update 1: There is a great collection of examples over at dzone.

Update 2: Found another nice tips and tricks post over at dzone.

Update 3: One more to check out.

First make sure that you are able to login to the remote host using ssh key authentication.

Basic Syntax

To sync files from a local directory to a remote directory use the following syntax:

rsync {options} -e ssh {source} {dest}

Example

Here is an example that exclude all .psd and .fla files:

rsync --exclude *.psd \
        --exclude *.fla \
        -avz -e ssh /local/dir/ user@remotehost:/remote/dir/

Archive a group of files:

tar -czvf archive.tar.gz file1 file2 file3

Archive an entire directory:

tar -czvf archive.tar.gz directory/

Extract a Compressed Archive

tar -xzvf archive.tar.gz

List the Contents of a Compressed Archive

tar -tzvf archive.tar.gz

Common tar Switches

• -c create a new archive
• -x extract files from an archive
• -t list the contents of an archive
• -z filter the archive through gzip
• -v verbosely list files processed
• -f filename of the archive (filename must always immediately follow)

ssh-keygen -t dsa

When prompted for a passphrase you can leave it empty to enable logging in without a password (please note that there are potential security issues with doing this).

After confirming your passphrase at the second prompt you’ll find two new files (the keypair) in your ~/.ssh directory. The first file id_dsa is your private key, the second file id_dsa.pub your public key.

Step 2: Set Local ~/.ssh Permissions

chmod 700 ~/.ssh

Step 3: Copy Public Key to Remote Server

scp ~/.ssh/id_dsa.pub username@remoteserver:~/id_dsa.pub

Step 4: Login to Remote Server:

ssh username@remoteserver

Step 5: Update Authorized Keys on Remote Server

cat id_dsa.pub >> ~/.ssh/authorized_keys

Step 6: Set Remote ~/.ssh Permissions

chmod 600 ~/.ssh/authorized_keys

Done!

At this point you should be able to login to the remote server without using a password.

ssh username@remoteserver
 - or - 
ssh -i ~/.ssh/id_dsa username@remoteserver
