Secure DMG with DiskUtility © 2006 Lawrence I. Charters Washington Apple Pi Journal, reprint information Use a Mac for more than a few weeks and you’ll discover it quickly accumulates vast amounts of personal information. The Mac offers a powerful tool for the paranoid in Mac OS X 10.4: FileVault. Unfortunately, FileVault also has a dark side: if you have problems with your hard drive, FileVault may prevent you from recovering your own data. If you use a Mac at work, you will probably find your employer prohibits the use of FileVault. Important disclaimer: the author has nothing against FileVault. But the Mac has another very powerful tool for the paranoid: Disk Utility. Portable, password-protected disk images have some wonderful advantages. Figure 1: Navigate the nested menus in Disk Utility to select New > Blank Disk Image… Depending on size, you can E-mail the disk image to yourself, copy it to a CD-ROM or DVD, copy it to a flash drive, or copy it to a file server. Launch Disk Utility.

Teach yourself to program We are entering the summer, the perfect time to improve yourself, you could go running or swimming, you could learn a new foreign language or perhaps you could learn to program. Self-learning is not as hard as it sounds, and it’s much easier than self-learning Spanish or French. There are really wonderful sources to start learning these new languages, understanding the concept behind programming and giving it a try with some interesting problems. Basic Programming Via XKCD To learn a new programming language, it’s much easier if you already know the concepts because you can start learning the new structures in no time. Programming Concepts : This is a brief tutorial for new programmers from the City University of New York. Learning a Language Whether you already know some programming languages or you are moving forward, you should choose a language to work with. Learning HTML Via Cyanide and Happiness HTML is quite a simple language that doesn't use variables or operations. Learning Python

All I’ve ever done was verify disk permissions, and maybe use Drive Genius to perform some optimisation. But even that was just something ‘extra’ and not necessary according to me. The real question is, can maintenance tools really help in getting your system speedy, healthy, and less prone to crashes? Maintenance A straightforward tool, as can be told by its name, Maintenance is a one window wonder. Ice Clean A much more comprehensive tool, Ice Clean is sort of your eyes into the system. When it comes to maintenance, Ice Clean can run the usual system scripts, disk verification and other forms of cleanup. MainMenu A no fuss application, MainMenu resides as an icon in your menubar. Onyx The big name in Mac maintenance, Onyx allows you to run a whole lot of maintenance scripts, along with cleanups of internet, fonts, logs, etc. MacPilot TinkerTool Cocktail Verdict

Blog Archive » Who Needs a Computer Science Degree When There’s Wikipedia? Update1 [6/25/08]: Welcome Stumblers Update 2 [11/20/08]: I stumbled on this GREAT list of Algorithms, highly recommended reading. I was looking up a computer science term on Wikipedia the other week and as is wont to happen, one thing led to another and I was about 5 or 6 articles deep on a trail of discovery and research to build up my knowledge. As I realized I was randomizing myself and getting way off the original track, I decided to start assembling the links in one location for my own reference if not some other geek without the funds for their own degree. Yes, there’s much more that I don’t have below, I wound up throttling back quite a bit after a while to leave it as is…for now. History: Extra Credit: Animated Sorting Algorithm Demos Languages: Computer Science Fields: General CS articles: Mathematical foundations Mathematical logic Boolean logic and other ways of modeling logical queries; the uses and limitations of formal proof methods.
