I still haven't started my wife's iBook hard drive replacement due to the fact that I'm just dreading doing it. I'm tentatively putting it off until after Christmas when I'll have more dedicated time. In the meantime...

Internet Explorer for Mac
It seems that Internet Explorer for Mac is finally going to be cancelled:

I'm never really used it, so it doesn't really matter to me personally, but it is really a bit of an end of an era.

In the "Fun Utilities" department, coconutIdentifyCard gives you detailed information on where your Mac (and/or iPod) were made, and is available here:

Tiger-style menu bars in Cocoa
And finally, if you're looking to add the Tiger style menu bar to your Cocoa application, it's simply. In Interface Builder, simply go to the Inspector for the NSWindow in question and under "Attributes", select "Unified title/toolbar look". Voila.

So it looks like I'm going to have to go through the painful experience of replacing an iBook hard drive. It seems that my wife's iBook (which used to be mine) has had its drive fail (Disk Utility reports the S.M.A.R.T. status as "Failing").

I was actually just planning on sending it to Apple for repair, but I can't, for the life of me, figure out how to (!). A call to the 1-800-APL-CARE number sent me through a maze of separate automated menu systems from which I briefly emerged at one point to speak to an actual human, who unfortunately plunged me back into the maze. So I gave up and ordered a Hitachi 60GB 7200 RPM drive from Tiger Direct for $250 CDN with tax and shipping.

There are several step-by-step guides for replacing iBook drives - I'm following this one: Replacing the hard drive of a G4 iBook 800Mhz and recovering of the built-in mike.. I expect to spend most of a day and all of my patience doing this.

A useful tip, by the way:

Even though there are some pretty elaborate tools out there for keeping organized, I still find myself using Stickies constantly. It's always been a bit of a pain scrolling them though, so I was interested in this article from Macworld (which ends up working quite well):
