There’s been some ballyhoo about the removal of the ringtone editor from iTunes 10 and some folks are recommending GarageBand or other applications and/or websites to do the conversion.

Stop.  That’s not what you do.

What you do is make iTunes do it anyway.  It has all the tools and you don’t need to go anywhere else.

Of course, the instructions for how to do it are a little silly.There's more »

I was writing some shell scripts the other day and I had to find which OS X version I was running and based on the OS X version I was trying to install my application. So this is a small and easy tip as to how you can find out the OS X verison using the default command.

OS_VERSION=`/usr/bin/defaults read “$3/System/Library/CoreServices/SystemVersion” ProductVersion`
echo “$OS_VERSION”

You can also get more specific if you want only the major version or the minor version by piping the OS_VERSION to ‘cut’ command by specifing the fields.

OS_MAJOR_VERSION=`echo $osversion | cut -f2 -d’.’`
OS_MINOR_VERSION=`echo $osversion | cut -f3 -d’.’`

Since I use Mercurial and it doesn’t have Xcode integration, I find that I’ll have added classes or whatnot and they will not have been added to the repository and I’ll forget about them come checkin time. That’s bad.

So I thought about ways to remedy this, and after describing the issue to myself, the issue was clear. “When I add new files to the directory, it should run hg add on the files.” Well, when when we need to do something when a directory changes, we use launchd yes? Yes.

So I made a launchd item that ran a script any time my specific repository changed. Since this is just for yourself, it can go in ~/Library/LaunchAgents. The item should set the current and working directories to the repository so the context of the hg commands is proper.There's more »

Ever get that lovely “overlapped extent allocation” or “missing extent” error when checking your drive in Disk Utility? Notice how it never gets repaired when you repair the disk? There’s a reason: it’s technically irreparable.

The extents that the error is referring to are the file fragments on your drive. There’s a special catalog file called the extents B-tree (this is also sometimes referred to as the extents or extents overflow file) that holds all of the information on which files have which fragments on the disk. Each fragment is an extent. When you have a missing extent then you have a record that states that there are a certain number of extents for a file, but the known extents are too few for that file.There's more »

CUPS is the name of the service that handles printing in Mac OS X 10.3 to 10.5. It has a lot of features that aren’t really pushed in the GUI in Mac OS X, but users are able to get at those features by using the special administrative interface at http://localhost:631/.

One of those features is classes. A class, in this context, is a group of printers that can be made to look as if it were one printer. This is great in lab settings where you have half a dozen printers of the same type as you can add them all to a class on a print server and have everyone print to that queue. Then whichever printer is free (or round-robin) will print the job.There's more »

If you move the Leopard dock to the side of the screen you get a dock with a gray background rather than the glassy surface. If you want that dock on the bottom of the screen as well, simply run the following:

defaults write com.apple.dock no-glass -boolean YES
killall Dock

This sets a hidden default on the Dock and then forces it to restart.

There are a plethora of hacks to change the translucent menu bar in 10.5. While I doubt the sanity of the UI designers at Apple with this release of the operating system, it is relatively easy to change this behavior without installing third party hacks.There's more »

I went to the GUI feedback session at WWDC last year and in the midst of all the yelling and screaming over the new dock and menu bar there was one guy with a wholly different mission: be able to turn off tooltips. His complaint (a valid one, I feel) is that every time he wants to sit and think about what’s on-screen, a little yellow box comes up where the mouse is, and there’s no real “safe spot” for the mouse that doesn’t do this in most applications.

So, I present a little tip I discovered shortly afterwards and appear to have not written up. I dedicate this to Tooltip Guy, wherever he is.

defaults write -g NSInitialToolTipDelay 99999

You now have 99.999 seconds to think at a given time. Replace -g with the ID of any application to change it in that application.
