The fastest way to browse your directories in OS X is clearly the column view that you access by pressing Apple-3.

However in this view long file names are usually partially hidden, which can be a problem. Worry not, there is an easy way to resize the width of these columns. Just drag the separator line at the little handle at the bottom. This operation will only change one column at a time.

Google launched Sidewiki, a new feature of the Google Browser Toolbar. It let's you comment on web pages in an collapsing side window. See the video for details.

When something goes wrong with your OS X operating system or your Applications you can try several things before getting upset about it:

1. Quit all unused apps - If you have a memory issue this will solve it.
2. Restart - Most of the times this is a quick solution.
3. Repair permissions - Open Applications/Utilities/Disk Utility, select your HD and Verify then Repair your Permissions.

You must have noticed an annoying little bug in Snow Leopard. When you try to open multiple files it only opens one at a time. Unfortunately I couldn't find a perfect solution, but there is an intermediate workaround until Apple fixes it.

Snow Leopard (OS X 10.6) introduced 4-finger trackpad gestures for MacBooks and MacBook Pros.

If you swipe down with four fingers you will activate Exposé to show all your active windows. If you swipe either up or down Exposé gets deactivated.

If you swipe up, your desktop will show. To deactivate you can again swipe up or down.

Most web services like Twitter for example require a unique email address for each account you create. What if you want to create two or more accounts, but only have (or want to use) one Gmail address?

You Gmail address has a unique feature. If you put a dot in between any of the letters within your id the email still arrives to the same mailbox. So for example if you email address is: john.doe@gmail.com all the below addresses are valid and will arrive to the same inbox:

• j.ohndoe@gmail.com
• jo.hndoe@gmail.com
• j.o.hndoe@gmail.com
• j.o.h.n.d.o.e@gmail.com

You can use each to sign up for a different Twitter account and stay organized within one Gmail account.
