Multi-tasking

It is somewhat ironic that I would praise Apple for the multi-tasking capabilities built into OS X, given that the Mac OS trailed Windows in its support for preemptive multi-tasking. Needless to say, the mistakes of yesterday are not true of OS X today, and its multi-tasking prowess was my biggest draw to it.

Multi-tasking under OS X works just like it would under Windows; you have multiple applications open, some of them doing things concurrently, while others are waiting for your input. I will address the two types of applications in a multi-tasking scenario separately.

In the case of applications running at the same time while performing tasks concurrently, OS X does one thing very well that Windows does not - the foreground application is never intruded upon by any other application that's running. Say you're encoding a video and typing a document in Word, should a dialog box popup in the encoding application, it will do it without shifting the window focus to that application. Instead, the dialog box will pop up in the background and you're free to dismiss it when you're ready and willing. It is all too often that Windows left me annoyed by a dialog box taking focus while I was typing a message to someone online or writing a document.

OS X has been designed to be as unintrusive to the user as possible. For that reason, one of the basics of the Windows interface is not echoed in OS X. While double-clicking a file or folder will open the item, hitting "enter" when one is highlighted will not cause the same effect. Instead, if you hit "enter" on a highlighted item, you'll be able to rename the item. In order to launch the file or open the folder via keyboard, you have to hit Command-Down Arrow (Command-Up Arrow will traverse up a folder tree). This takes a bit of getting used to and if approached with an open mind, you can get used to it in a couple of days, but it can be frustrating at first - especially if you are a keyboard addict used to Windows.

Another way in which OS X allows for less intrusive multi-tasking is in its ability to let you close a background window of an application other than the one you're currently working in without shifting focus to that application. Say that I have a browser window open behind a Word document that I'm typing. I can hover over the red close button on the browser window and click it without actually shifting focus away from the Word document - I can continue typing away right after clicking the browser's close button without any additional mouse use.

Next, there is the more frequently used type of multi-tasking, where multiple applications are open and the user switches between them. I've already mentioned that OS X has the equivalent of the Windows ALT-TAB functionality; the task switcher is activated by holding down the Command key and hitting "tab" to sequence through all of the open applications. Releasing Command activates the selected application and everything continues as it would under Windows.



Command-Tab in action. The more applications that you have open, the smaller each icon becomes as the Command-Tab list grows in size.


There is also the equivalent of the taskbar, which in OS X is best likened to the "dock". The dock is a fully customizable bar at the bottom of the OS X desktop (you can position the dock along any side of the screen that you'd like) and it contains application launch icons for applications to which you want quick and easy access, as well as icons of any running applications. If a running application already has its icon in the dock, a little arrow appears under the icon to denote that it's running; if not, the application's launch icon will appear to the right of the dock. The dock does have a divider to which you can also drag folders and links; to the right of this divider is where minimized windows go (with a very nice accompanying animation). Clicking on any application's icon in the dock will either launch the application if it's not already running or it will switch to that application; but, of course, that requires using that pesky mouse.

    You again failed to provide proof. The first site is a bunch of pictures. I have been to that campus and have met some of the people in those pictures. This is how funding works, if someone gives you money and says that you can only spend it on x, are you going to give up that funding? NO

    Now, let's take a look at comparing 2 exact same items. They will never perform the same. Do you know why? There is about a billion reasons why. The mos striaght and to the point example is the movie "Timeline." Look at post #97.

    The only one that came close to proving me wrong was the linuxsinder.com post. Problem is, he doesnt tell me what vendor he is going to except for dell and the things is I just did a price comparison on both those items. I have given the direct links to the vendors.

    With some of the last links you posted, go back to post #112.

    Azkman has already answered #112 very well, but just a quick look at the Dell shows it only has 2 HD bays, neither front accessible nor hot swappable. It's not 64-bit, and doesn't have a 1GHz front-side bus. I'd guess there are other reasons it's not in the same comparison class as the Xserve G5, but I think that's plenty already.

    Hard evidence for #112 (none from pro-apple sources):

    Specs do not equal performance. I haven't heard of any Dell supercomputers being built at breakthrough prices. I'd believe the jugdement and results of VT and the US Army over an arbitrary price comparison any day.

    I just did a price comparison of my own between an xserve and a dell server.

    Here is the xserve for $2898.99

    I priced a rackmount server with the same specs on dell.com for $2021

    #95 Don't post an article that explains one system and then say it is more cost effective for what you get compared to another system when the article doesn't even mention a price for the system they are describing. Do not attack my post unless you have some hard evidence.

    reading all these comments from (most) the mac users that have posted makes me want a mac less and less.

    -- I second that one. $2500 for a computer with no monitor and a crap video card. That's the "uncomfortable" part to me.

    Care to elaborate? Using this same sort of reasoning, then all of the positive comments a people might happen to make about their own country should dissuade foreign tourists from visiting. And of course, such people should not object if their country is portrayed in a bad light by foreigners who know little or nothing about the country. What's more, the foreigners are afraid that a learning experience might actually force them to rethink their prejudices. To bring this discussion back on topic, what Anand has done is the equivalent of visiting a foreign country, sampling its cuisine, experiencing something of its culture, and so on. His "travelogue" describes his impressions. The forum participants chime in with their own dispatches from the field -- and those who have visited and perhaps lived in the foreign country for some time are in a better position to comment knowledgeably.

    And if that's all it was, then the remedy is simple -- learn. But in the article, as well as in the comments, uncalled-for remarks about price etc. detract from the overall message that it is quite possible for a diehard but open-minded Windows PC user to discover genuinely superior things about MacOS X even without delving into applications that make best use of the platform.

    I don't think this article was to compare which system (hardware or software wise) is better. It was written to describe the "experience" one would feel when switching to another OS (heck, the same thing could be said about switching girlfriends or boyfriends).

    I started my computing days using the Apple IIe, then the first Mac...eventually I switched to the Windows platform, and recently since my wife got an iBook, I had to switch back to OS X.

    Basically, this article describles the "uncomfortable" feeling we get when we switch to something we are not used to...A feeling I experienced many times over. All the speed, power, and storage of a system could mean nothing to me if I don't know all the ins and outs of what I'm using to get what I needed done.

    Overall, the article was a good and interesting read...just wish there was more on the audio/video apps (where Apple truly excel), however I assume it's not what the author's primary use of the G5...but hopefully a start towards many more articles.

    A quick FYI semi-related to Mac OS X scroll speed. Clicking in the empty area of a scroll bar jumps by a page, but clicking while holding down the "option" key jumps straight to that point (reversible via a system preference). This comes in very handy for long documents (or file listings), when you know about where you're trying to go.

    As an aside, the only app I have seen where this does NOT work is MS Word....
