In iTunes, a very useful feature is the File » Show Duplicates menu item. As expected by its name, you can use this feature to help weed out duplicates from your iTunes library. However, many people (myself included) have different versions of songs, remixes and such, which will show up as duplicates when using this feature.

The solution is to hold down the option key prior to selecting this menu item. When you do, Show Duplicates changes to Show Exact Duplicates. In this mode, iTunes shows only true duplicates, and not remixes or alternate versions.

There are several hints on this site for unmounting a partition at login, but a better way to make this happen can be used. You need to create an entry point in your filesystem table to tell the OS not to mount that specific volume, and this is relatively easy. In Mac OS X, and under Linux and others unix systems, the volume mounting configuration file is located in /etc/fstab. This file in Mac OS X Tiger is empty in Panther, its commented, but type man fstab in Terminal to read some important information.

All credit for this hint goes to Jeff Johnson of Lap Cat Software, who blogged about the solution. This hint is a significant update to this one, which pointed out you can use Control-click to get the old-style contextual menus. [robg adds: To undo this behavior, you can either change no to yes in the above command, or delete the key entirely with defaults delete com.apple.dock show-expose-menus; killall Dock.]

This one goes out to all the night owls. As much as I love my iMac, I was surprised to see how little control it gave me over the screen’s brightness. I often work on my iMac late at night in an otherwise darkened room, and even at the lowest brightness setting, the iMac is really, really bright. All of the Mac laptops I’ve used have the ability to dim the screen down to completely dark, but the iMac does not.

A debugger is a program that facilitates debugging, which may be casually defined as the process of finding and fixing “bugs” in the object of interest: usually a piece of software, firmware, or hardware (although debugging may apply to any domain).

My daughter’s music CD for her skating short program got badly scratched and because it was the last-but-one copy as skater you need many copies, in case you loose/forget/scratch/misplace it,  I was confronted with the task to create a new copy. Rather than starting Nero on Win-XP notebook, I have decided to learn finally how to do it on Mac. It must be simple, intuititive and much easier than on Windows. Right ? Wrong To my big surprise, there was no easy, idiot proof, very obvious way mac-ish drag and drop way how to acomplish it. It was not exactly hard either, but it actually took consulting the omniviscent Google to find it out. To save the search for the next time, I’ll write it down. Here is what you have to do:

1 Create a disk image from source CD

Insert the source CD the one you want to copy

Open the Finder, open Applications, then Utilities, and start the Disk Utility program

In Disk Utility, select File -> New -> Disk Image from Folder

The Finder will appear – select whole CD and click on the Image button

A new dialog box will appear. In the Where box, choose Desktop. In the Image Format box, choose DVD/CD master

Click Save

Now a new file will be created on your Desktop, titled the name of your CD with a “.cdr” extension. This file is a disk image of your CD. Btw, it works even if you do not select cdr format and write disk as generic Disk Image .dmg.

Now you need to burn it on new, blank CD:

2 Create new CD from a disk image

Eject your original CD from the CD drive

Return to the Disk Utility program.

You should now see the disk image of your CD on the left hand side, typically at the bottom of the list. Select the image, and then click on the Burn button

Follow the directions and insert a black CD-R disc when prompted

You can repeat step 2 as many time you need, of course . Next time I am going to use the image, of course assumed that it will be still the same music. Thanks to Spotlight magic, I am sure I will be able to find it, because I used proper, descriptive and obvious name “track 86.cdr”. Just kidding .

What do you think – why did not Apple make this process easier – as they did for many other chores ? Has it maybe anything to do with the fact that copying CD can be and quite often is used for copyright violation activities ?

As with any other network service, Screen Sharing has a set of virtual “ports” which isolate network traffic for that protocol since it and web traffic and other network services are all using the same IP address and connections. These ports must be opened in all network devices for all computers involved in the screen sharing sessions. This means firewalls on the local computer, as well as any routers or hardware firewalls must also be set up to pass traffic on the following ports:

TCP: 5900 – 5902, (3389 for connecting to Windows machines)

UDP: 4500 (for Back to My Mac users)

Depending on the network devices used, these ports can either be opened completely, or forwarded to the local IP address for the desired computer, but you will have to consult the documentation for your router to see about how to change these ports. Additionally, if your router supports “UPNP” (Universal Plug & Play) or “NAT-PMP” (NAT Port Mapping Protocol), then it should work for Back to My Mac. The list of routers in this Apple Knowledgebase article are some that support Back to My Mac and other screen sharing.

We highlighted the phrase “after a user is verified” deliberately: it should be explicitly understood that only a simple query stands in the way of an evil hacker and the powerful admin area of your whole blog.

Start by go to the Accounts pane in System Preferences, and find the “short name” of each user you want to hide. Once you have these, open up Terminal and enter the following:

sudo defaults write /Library/Preferences/com.apple.loginwindow HiddenUsersList -array-add shortname1 shortname2 shortname3
