    Now these lines tell me that two kernel modules are involved, com.apple.filesystems.afpfs and com.apple.iokit.IOGraphicsFamily. The first one is related to AppleTalk and the second probably to your video card. To eliminate these as possible problems you should turn off AppleTalk (System Preferences->Network->AppleTalk and uncheck Make AppleTalk Active) and you should try reinstalling your video card drivers.

    However you didn't say if you have added anything to the computer, such as RAM. Very often a bad stick of RAM can cause the types of panics you are experiencing. I say this because a lot of the panics don't seem to involve kernel modules. Even those panics that did involve a kernel module could be caused by RAM problems. To see if this is the case try booting from the hardware diagnostic disk and run hardware tests. If nothing comes up then try shutting down and removing 1 stick of RAM (after market RAM first) and then starting up. See if your system is more stable without it. If it is then that RAM is probably bad, if not repeating this with another RAM stick.

    Worst case, do a reinstall of your OS. Here is a PDF of the process.

    I hope this helps you out!

    That's very unusual, you have to have something corrupted. I admin around 40 Mac OS X 10.2 machines and haven't had a kernel panic in at least 6 months.

    First of all, try running Disk Utility (found in /Applications/Utilities/). Click on your boot partition at the left and hit the button on the right "Repair Disk Permissions". Sometimes those get messed up and programs that need to run with certain permissions can't do so and crash. SecurityAgent is one of those. It's probably also a good idea to boot off of the System disks that came with the computer and do a Repair Disk with Disk Utility, just to be sure.

    Also take a look at these discussions to see if it relates to your problem:
    Nvidea-related kernel panic
    Keychain-related problems

    Can you post the kernel panic log? Here's some info on how to find it:
    Mac OS X: What Is a Kernal Panic?

    If you post the log and stuff like what OS version, type of computer, was any new hardware added to the system (including memory), etc. I'll see if anything jumps out as a problem. Like I have said, your situation is very unusual and it should be taken care of.

    That's odd, why is it hanging so much? I haven't had a true hang or crash with Mac OS X in about 6 months or so. It might be a bad driver or a corrupted NetInfo database. Take a look at /var/log/system.log and see what is the cause of those hangups. Often you can see what is the cause by the number of tries as the system attempts to do something like a NetInfo lookup. There are several ways to fix these problems, a quick Google should help you out with that.

The cool thing is that the latest Objective-C compilers can also use C++ code so that you don't need to re-write old code.

    Basically Objective-C is C with objects, but done in such a way that it doesn't feel like the object-oriented stuff is just bolted on.

    We had a severe ice storm and most of blacksburg lacked power. but so did campus!

    It's probably the same problem the North East had a few months ago. One set of power generating equipment goes out and several closely related systems do the same. This is because when one part of a grid goes down the demand suddenly shoots up in another part, overloading circuits. These circuits automatically shut down to avoid burning up. When enough gets shut down the power plants also shut down to avoid mucking up the situation further.

    That power plant you are talking about was probably still able to generate but since the transmission system was mucked up it was not able to provide power. The thing is, if these systems were designed a little better and were better able to split up into smaller independent grids then we would have less problems when one of them goes down.

    NSRangeException: [NSCFString substringWithRange:]: Range or index out of bounds</blockquote

    Ok, to break this down:

    NSRangeException - This is an exception raised by an error condition in Objective-C code, from the Next Step libraries (actually Cocoa, but it's descended from Next Step

    NSCFString substringWithRange: - The exception is raised when messaging the NSCFString class through the substringWithRange method

    Range or index out of bounds - either the number sent to the class was too large or it referenced a value beyond the end of the class. Most likely the string the program was attempting to substring was too large and instead of overflowing the program threw an exception.

    The good thing is that Cocoa is largely protected from buffer exploits because it generally checks the bounds of arrays before dumping data into them. If something would overflow the array then it will most likely throw an exception rather than doing something bad. Thus, Cocoa programs are generally pretty secure - as long as you don't break the functionality by circumventing it and rolling your own standalone classes.

    I never really understood the concept of "number of CD burns" restriction. Seems to me that if you could burn the audio tracks once to a CD, then you could just copy the copied CD, or rip the files to mp3 and do whatever you want with them.

    Actually all you need to do is change the order of the songs in the playlist and you can then burn them another 10 times. I believe even adding a 1 second blank track to the end of the playlist would work also.

    I think the point is that it is a tiny speed bump to trip up someone who is trying to mass duplicate a downloaded CD. No one who has a legitimate use for the CD is going to realistically need to burn it more than 10 times so most people won't be bothered by this limitation. However, someone mass duplicating the CD would have to fiddle with it every 10 tries and would not create a perfect copy after they moved stuff around.

    So yeah it's just a nod towards DRM but it's enough to get the music companies to allow Apple to sell their stuff. Remember that Apple is the first to get a bunch of major labels to agree to selling individual tracks electronically. In order to do this there had to be some roadblocks to mass duplication.

    Files *created* by iTunes when you rip your CDs are standard AAC files. However, files downloaded from the music store are NOT standard AAC files, and the DRM is most definitely NOT "volutarily enforced" by itunes. They are encrypted and keyed to the computer which you license with Apple.

    There is no such thing as a standard AAC file. AAC (Advanced Audio Coding) is a codec, not a file format. The AAC files created by iTunes are actually .m4a files and the files that come from the iTunes Music Store are .m4p files. Basically the m4a and m4p files are Quicktime files that use AAC encoding to store music. The m4a data is unencrypted and the m4p data is encrypted.

    Other players could definitely play the m4a files if they worked out the file format. Knowing Apple the file format is probably readily available to developers. The m4p files, by nature of the encryption, would require either cracking the encryption or partnering with Apple in order to play on a 3rd party music player.

You replaced the fans on that computer without making sure that the replacements had the same airflow. The computer overheated so you got a completely different type of heatsink than the one that came with the computer. The heatsink didn't fit but you retrofitted it onto the processor. Then computer went completely belly-up. Face it, you didn't improve the computer in any sort of way, you made it worse and it malfunctioned.

They have been extremely successful with iTMS for the Mac which has encouraged more artists to sell their songs through the store, building up the music catalog. Now there is news that Apple may have the Windows software finished early. A quote from the article:
    And Apple, NEWSWEEK learned, quietly informed some music insiders that it's moved up the date for expanding its current Mac-only iTunes for the vast universe of Windows-based PCs to mid-October.

    Dell products that will be available for purchase in time for the holidays include a digital music player, online music service, multifunction LCD television and computer monitor, a home entertainment projector and a wireless handheld.


    There are almost no details about all of these things. It doesn't say what artists will be available on the music service. It doesn't say the size of the player, it's features, what formats it supports, how large the hard drive, the price. It doesn't mention much about the multimedia application other than saying it will be an "important tool".

    Frankly right now all this amounts to vaporware. Apple has products out for months or years that have proven themselves and made waves. People drool over the iPod and compare any new music service to iTMS. Dell's offerings, even if they come out in time and are amazing, are going to take time to build a user base. In the meantime Apple will have the lead and as long as Apple continues to innovate it should maintain a lead. At the very least the two might split the market down the middle, leaving a very nice chunk for each of them.
