A colleague of mine is a recent Mac switcher and he was complaining to me that virtual desktops are not included in Mac OS X, the irony is that they are, they just have the name Spaces (coming from a heavy Linux background, I guess the naming convention just threw him off). Virtual Desktops are a very common and popular feature in most Unix GUI’s, but as Mac OS X has included virtual desktops within Mac OS X too. 
Tye Campbell wrote to us with the following question: “Do you guys know how to take apart an iPhone? Specifically the 3G model, I can’t find any way to get to the display and I’d like to do my own screen replacement since mine is cracked but I have another one available to me from a water-damaged iPhone.

Mac OS X Server is infinitely better equipped, more stable, and just generally more pleasant than any of Windows offerings (yes I am biased, but it’s true), if you’re needing a server I highly recommend checking out Apple’s offering. Instead of shelling out the $499 for a copy though, you can get a free evaluation copy! If you’re a large corporation, small business, nonprofit organization, government agency, or educational institution, you can get a free and fully functional evaluation copy of Mac OS X Server directly from Apple. I just found out about this and I think it’s a pretty great thing for Apple to do, so if you qualify for a copy, check it out and you will be impressed.
If you’re ever wondering how long your Mac has been turned on and running for, you can discover exactly how long the computer has been on since last boot with two different methods available in OS X.
You can delete specific pages from a PDF file with the built-in Mac Preview app, available in all versions of OS X. This is really useful for paring down large PDF documents if you only need a few select pages, and learning how to delete specific pages from PDF files is bound to make any student or researchers life easier when emailing or printing documents.
