SSH Dialog

If you don’t want to store your passphrase in the keychain, the above dialog will appear every time you use the ssh tool with your private key. It’s so boring, isn’t it? Ok, ssh-add can solve it.

ssh-add <private key file>

It adds your private key to the SSH agent. After using this command, you won’t see that dialog again in the current system login session.

1. Apache

To enable Apache, check the Web Sharing in System Preferences > Sharing.

2. PHP

To enable PHP, open Apache’s configuration file (/etc/apache2/httpd.conf) and enable the following line:

LoadModule php5_module libexec/apache2/libphp5.so

After modifying this file, you should restart Apache by unchecking/checking the Web Sharing or using the following command:

$ sudo /usr/sbin/apachectl restart

3. MySQL

First, download MySQL’s installation package for Mac OS X (dmg) from MySQL’s website. It’s not included in Leopard.

There’re two Installer Package (pkg) files in the file you downloaded. One is the installer of MySQL, the other named MySQLStartupItem.pkg is used for starting MySQL automatically during system startup. Furthermore, a Preference Pane file named MySQL.prefPane lets you start/stop MySQL in System Preferences > MySQL.

After installing MySQL, configure PHP to work with it:

$ cd /etc
$ sudo cp php.ini.default php.ini

Then open this newly created php.ini and set the mysql.default_socket and mysqli.default_socket to:

mysql.default_socket = /private/tmp/mysql.sock
mysqli.default_socket = /private/tmp/mysql.sock

Restart Apache again and you have the AMP on your Leopard now!

$ sudo nvram boot-args="-v"

Enjoy!

iCal’s Icon

But why is it July 17th? Steve Job’s birthday? Or a special day in Apple’s history? No. It’s just the day iCal was introduced to the public. Haha!

Figure A

Figure A shows a typical dialog in Mac OS. The button with blue background (OK in Figure A) is the default button of the dialog. You can always hit the Return key to select the default button, or hit Esc to cancel the dialog.

After hitting the Tab key once, you will see that there’s a blue glow around the OK button (see Figure B). It means that this button is highlighted and can be selected with the Space Bar at this time. And you can hit Tab again to highlight the Cancel button (see Figure C).

Figure C

But the Tab key is not available on some dialogs. So you should use ? or Command+? (? is one of the A-Z keys) to select a button other than the default and Cancel buttons. You can use Command+D (D for don’t) to select Don’t Save on the dialog that Figure D shows, and use S (S for sleep) to select Sleep on the dialog that Figure E shows.

Because the Cut is only for cutting the filename while you’re editing it. So how to move some items from one location to another in Finder? It’s easy, just hold down the Command key while dragging the items with your mouse. That’s all.

By default, dragging items from one location to another in Finder means that they’re being moved if the volume of the new location is the same as the volume of the orginal location. If the volumes of the new location and the original one are not the same, the items are being copied while dragging.

Furthermore, Apple’s document says that dragging items with Option held down will copy those items to the new location. And dragging items with Option and Command held down will make alias in the new location.
