Onbuddy's gadgets and electronics review.

For your info, Mac comes with a few screen savers. We’ll show you the steps to change the default one, create your own from your photo collection, and add third-party savers.

Please refer to mac basic faqs: how to change your Mac OS X desktop if you wish to change your Mac OS X desktop.

To Change Your Screen Saver

1. From the Apple menu, choose System Preferences to open the System Preferences window.
2. Click the Desktop & Screen Saver button to display its preferences.
3. Click the Screen Saver tab to display just the Screen Saver preferences. All installed screen savers appear in the left pane. The right pane displays a preview of the selected screen saver.
4. Click one of the Screen Saver items in the left pane to select it for use.
5. If you’d like, click Test to see what the screen saver will look like in use.

To create a slideshow screen saver, do one of the following:

1. In the Screen Saver preferences window, select Library or one of the two choices below it to turn your iPhoto images into a slideshow screen saver.
2. In the Screen Saver preferences window, select Pictures Folder to display the images in it, or select Choose Folder, navigate to and select a folder that contains images in the resulting dialog, then click Choose to put it in use.

To add a third-party screen saver:

1. If the screen saver doesn’t have an installer to place the file in the right folder, locate the .saver file in the package.
2. Drag the file into the Screen Savers folder, which is in the Library folder at the root of your hard disk ~/Library/Screen Savers.
3. Follow the steps in “swap your current screen saver for another one,” above, to select the third-party screen saver.

Customize Your Screen Saver
Now that you’ve outfitted your Mac with a new screen saver, you can further customize its settings. Here are some of the things you can do in the Screen Saver preferences window.

1. Click Options to view the selected screen saver’s user-configurable display settings and adjust them to your liking. These settings will vary screen saver to screen saver.
2. Move the “Start screen saver” slider left or right to change the time, in minutes, at which the screen saver begins to play.
3. If you’d like the ability to start the screen saver manually, click Hot Corners. In the resulting dialog, choose Start Screen Saver from any of the four corner pop-up menus and click OK. The screen saver will start when you move your arrow to your chosen screen corner.
4. If you’re the adventurous type, select “Use random screen saver,” and your Mac will automatically select a screen saver when it goes into screen saver mode.

Haha, there’s nothing wrong with keeping that same Leopard default image as your Desktop picture, but if you wish to change it, we’ll show you how to swap it for another of ours or one of your own. Your Mac comes equipped with more than the default picture; in fact, Apple preinstalls over 50 images to choose from. To change your desktop picture, follow these instructions:

1. From the Apple menu, choose System Preferences to open the System Preferences window.
2. Click the Desktop & Screen Saver button.
3. Click the Desktop tab; the left pane lists the different folders from which you can choose an image. The right pane displays thumbnails, small images, of the images in the selected folder.
4. Click Apple Images to select it. You’ll see the default picture in the right pane, along with a bunch of other images.
5. Click any thumbnail to instantly change the desktop image. Feel free to click a few different ones to try them out.
6. Now select Nature in the left pane. Then click any of its thumbnails to place a nature type picture on your desktop. Do the same for Abstract.
7. If you’d rather have a solid color desktop, select Solid Colors in the left pane, and select a color swatch from the right pane.
8. When satisfied with your choice, close the Preferences window.

Of course, you can turn any of your own photos or artwork into a desktop picture too. Here’s how to do this:

1. From the Apple menu, choose System Preferences.
2. In the window, click Desktop & Screen Saver, then click the Desktop tab to display just the desktop preferences.
3. If you want to use a photo from your iPhoto Library, select Library in the left pane. Otherwise, select Choose Folder, navigate to and select the folder that contains your image, and click Choose.
4. In the right pane, click any thumbnail to place the image on the desktop.
5. Depending on the size of your chosen image, you can opt to tile or center it if it’s small. Note: Your image will look pixelated or have jagged edges if it’s too small. Or have the image fill the screen, or stretch to fill the screen. Just choose an item from the pop-up menu that appears above the thumbnails, the one next to the thumbnail of your current picture.

You can also have your Mac automatically change your desktop picture. To do this:

1. Select the “Change picture” checkbox. Note: This option is not available if you selected your iPhoto Library or an iPhoto picture roll.
2. From the Change picture pop-up menu, choose one of the intervals listed in the menu (such as every minute or every day—or choose every 5 seconds for a desktop slideshow).
3. Select the “Random order” checkbox if you want the images to appear at random. If it isn’t selected, your images will appear in alphabetical order by name.

What is a windows boot disk?
A windows boot disk allows you to boot off of a diskette instead of your hard drive. This diskette can be used to fix issues that may arise during the lifetime of your computer and/or to help load older MS-DOS games.
Tips: After you have created a boot diskette, it is highly recommended that you write-protect the diskette to prevent possible computer virus infection and to help the diskette from being erased.

The following files are self extracting disk images that can be downloaded and executed to create the associated floppy disk(s).

How to use a windows boot diskette

1. Place the diskette into write-protect mode (in case a virus is on the computer, this will not allow the virus to transfer itself onto the diskette).
2. Insert the diskette into the computer and reset or turn on the computer to begin the boot process.
3. As the computer is booting, answer the questions prompted (if any).
4. Once at the A:\> take the appropriate actions depending upon the situation of the computer.

Q: What is linux?
A: The name “Linux” is used to refer to three similar yet slightly different things, which can be confusing to all but the hardcore geek. The three usages vary by how much of a complete software system the speaker is talking about.

At the lowest level, every Linux system is based on the Linux kernel — the very low-level software that manages your computer hardware, multi-tasks the many programs that are running at any given time, and other such essential things. These low-level functions are used by other programs, so their authors can focus on the specific functionality they want to provide. Without the kernel, your computer is a very expensive doorstop. It has all of the features of a modern operating system: true multitasking, threads, virtual memory, shared libraries, demand loading, shared, copy-on-write executables, proper memory management, loadable device driver modules, video frame buffering, and TCP/IP networking.

Most often, the name “Linux” is used to refer to the Linux Operating System. An OS includes the kernel, but also adds various utilities — the kinds of programs you need to get anything done. For example, it includes a shell (the program that provides a command prompt and lets you run programs), a program to copy files, a program to delete files, and many other odds and ends. Some people honor the request of Richard Stallman and the GNU Project, and call the Linux OS GNU/Linux, because a good number of these utility programs were written by the GNU folks.

Finally, software companies (and sometimes volunteer groups) add on lots of extra software, like the XFree86 X Window System, Gnome, KDE, games and many other applications. These software compilations which are based on the Linux OS are called Linux distributions.

So, there are three Linuxes: the Linux kernel, the Linux OS, and the various Linux distributions. Most people, however, refer to the operating system kernel, system software, and application software, collectively, as “Linux”, and that convention is used in this FAQ as well.

Q: Is linux unix?
A: Officially an operating system is not allowed to be called a Unix until it passes the Open Group’s certification tests, and supports the necessary API’s. Nobody has yet stepped forward to pay the large fees that certification involves, so we’re not allowed to call it Unix. Certification really doesn’t mean very much anyway. Very few of the commercial operating systems have passed the Open Group tests.

A: Unofficially, Linux is very similar to the operating systems which are known as Unix, and for many purposes they are equivalent. Linux the kernel is an operating system kernel that behaves and performs similarly to the famous Unix operating system from AT&T Bell Labs. Linux is often called a “Unix-like” operating system. For more information, see http://www.unix-systems.org/what_is_unix.html.

Q: Who wrote linux?
A: Linus Torvalds and a loosely knit team of volunteer hackers from across the Internet wrote (and still are writing) Linux from scratch.

Q: How is linux licensed?
A: Linus has placed the Linux kernel under the GNU General Public License, which basically means that you may freely copy, change, and distribute it, but you may not impose any restrictions on further distribution, and you must make the source code available.

This is not the same as Public Domain. See the Copyright FAQ, ftp://rtfm.mit.edu/pub/usenet/news.answers/law/copyright, for details.

Full details are in the file COPYING in the Linux kernel sources (probably in /usr/src/linux on your system). There is a FAQ for the GPL at: http://www.gnu.org/copyleft/gpl-faq.html.

The licenses of the utilities and programs which come with the installations vary. Much of the code is from the GNU Project at the Free Software Foundation, and is also under the GPL. Some other major programs often included in Linux distributions are under a BSD license and other similar licenses.

Q: How does one pronounce linux?
A: This question produces an outrageous amount of heated debate.

If you want to hear Linus himself say how he pronounces it, download english.au or swedish.au from ftp://ftp.funet.fi/pub/Linux/PEOPLE/Linus/SillySounds/. If you have a sound card or the PC-speaker audio driver you can hear them by typing

$ cat english.au >/dev/audio

The difference isn’t in the pronunciation of Linux but in the language Linus uses to say, “hello”.

For the benefit of those who don’t have the equipment or inclination: Linus pronounces Linux approximately as Leenus, where the ee is pronounced as in “feet,” but rather shorter, and the u is like a much shorter version of the French eu sound in peur (pronouncing it as the u in “put” is probably passable). 

What is meebo? It’s a web messenger that lets you access IM from absolutely anywhere. meebo supports msn, yahoo, aol/aim, google talk (gtalk), jabber and icq.

What is https? https is known as “Hypertext Transfer Protocol over Secure Socket Layer”, but now https may be secured by the Transport Layer Security (TLS) instead of Secure Sockets Layer (SSL) protocol.

To invoke https, we simply replace “http://” with “https://” in the Uniform Resource Locator (url), or Web address. https connections are often used for payment transactions on the Web and for sensitive transactions in corporate information systems.

By using https (https://www.meebo.com) instead of http (http://www.meebo.com), all the data is encrypted and protected for additional security. You can try it.
