    note that $120/year is cheaper than $7500

    Look at it this way, for $120 a year you would be buying 12 albums a year at $10 each at the iTunes Music Store (iTMS). You would then own these songs and pretty much be able to do whatever you want with them. Even if you go broke and can't pay $120 for the next year you will still have the songs if you buy them.

    Many people buy less than 12 albums a year so those people will save money by using iTMS rather than renting the music. I seriously doubt that anyone will fork over $7500 all at once to fill their iPods. The reason most people get a 30 meg iPod is not to fill it with new music but to put in the songs bought over the years, along with some new stuff. Not only that but the iPod has many uses other than to store music - I use it all the time to move gigs of files from one machine to another in work, or even as a quick way to boot up a machine if I'm a pinch.

    Lastly, I know for a fact that Apple's DRM can hardly be called a DRM. How many people would HONESTLY have a reason to use an audio file on more than 3 computers? Even if you did how hard is it to burn a CD with the songs and then use that CD on as many computers as you want? Judging from Microsoft's history I just don't see them offering DRM files with this degree of freedom. You know for sure that you won't be allowed to burn standard CDs with Microsoft's rental service, if you could then you would now own that song forever and the rental idea would be dead.

    You mean like this program? It takes the audio output from pretty much any source, including a running program like iTunes, and encodes it into mp3 or AIFF. It can even pipe the sound data into a command-line program so you can encode using FLAC, Lame, Ogg, or whatever.

    Pretty sweet program. You can even use it like to do timed recordings of internet radio shows, kind of like a Tivo for streaming audio.

    You are, of course, completely correct. I don't know how I managed to get THAT screwed up but I did.

    My best numbers for a TRUE four coin system come up to be 1, 3, 10, 32. My calculation for the number of coins needed for change with these numbers is 4.16 coins per exchange.

    Now I see that there is apparently some difference between how I calculate coins exchanged and how the author calculates them. I calculated the coins exchanged by the "greedy" method. With this method you take the change amount and first use as many large coins as you can, then next smaller, and so on. Doing this for every amount of change from 1 to 99 cents, adding up the total coins used, and dividing by the 99 solutions I get the following values:

    US 5 coins:
    1, 5, 10, 25, 50 = 4.24 coins per exchange

    US 4 coins:
    1, 5, 10, 25 = 4.75 coins per exchange

    Shallit's 4 coins:
    1, 5, 18, 25 = 4.63 coins per exchange
    1, 5, 18, 29 = 4.49 coins per exchange

    My 4 coins:
    1, 3, 10, 32 = 4.16 coins per exchange

    My 5 coins:
    1, 3, 6, 16, 40 = 3.60 coins per exchange

    Why do my calculations differ from Shallit's? I'm not sure, it is probably related to the use of the "greedy" method. For example: with the set of coins {1, 5, 18, 25} I could use the greedy method make change for 36 cents. This would be a 25 cent coin, a 10 cent coin and a 1 cent coin = 3 coins. A more optimal solution would be to just use two 18 cent coins = 2 coins. Shallit suggests using the Pearson method of allocating coins and I haven't bothered to do this, so I don't know how my coin selection would turn out against that.

    Ahh well, just goes to show that you should never post something in one sitting. Write it off to one side and come back and check it before it is posted. Good thing this is just a web forum and not some major bridge engineering project or we'd all be really screwed! :)

    I had a little more time to fool around with the numbers. This time the best result I was able to come up with a 4 coin system is using 1, 3, 7, 16, 40. Using these coins I would give an average of 3.49 coins in change, easily beating the system proposed in the article.

    For a 5 coin system I came up with the following coins: 1, 2, 5, 10, 22, 47 - with these coins I would need 3.25 coins per transaction, again better than his 5 coin system.

    It really doesn't matter how efficient any of these systems are, they are a pain to make change with. The old 1, 5, 10, 25 system works just fine and is easy to use, why "change" it? :)

    By the way, for anyone who wants to know how I came up with the values I used here - all I did was assume that 100 cents was the 5th result in a power series (for the 4 coins) or the 6th result in a power series (for the 5 coins). I then calculated the base (b) for the power series by taking the 5th root of 100 or the 6th root of 100. I then calculated b^0, b^1, b^2, b^3, b^4, b^5 and rounded them off to the nearest integer. These numbers were my base coins. I then treated them as the number positions in a n-ary number system and used a quick algorithm to make change for 1 to 99 cents, adding up the number of coins used and dividing by the number of cases (99) I went through.

    Hey, I can beat this guy at this math thing. According to my calculations there are much more efficient combinations. For example, if you use the coins 1, 2, 4, 8, 16, 32, 64 it will take approximately 3.19 coins per transaction (this is simple binary arithmetic). That's way better than his system which takes 3.89 coins per transaction. The only problem is that the geeks will do just fine with these denominations but just try and ask the average waitress to make change using those coins. Go ahead and ask, I'm sure it will work out just fine! :)

    You know, if we mint 1 coin for every amount of change (like a 57 cent coin, a 58 cent one, etc.) then it will only take 1 coin per transaction. Of course then we have to worry about having 99 different coins, making them distinguishable from each other, etc.

    The current United States system of currency works just fine. Denominations of 1, 5, 10, 25 are easy enough to calculate and efficient enough for all intensive purposes. Sure this proposed new system may be 17% "more efficient" for a computer but real people need to use the system also.

    Depending on how DRM is implemented, you may not be able to easily back up and restore the music from CD. Because under these models you don't have the right to freely copy the data that makes up that music.

    No such problems with the music you download from Apple. Although you are limited to playing the songs on 3 different computers (which you can switch at will to 3 completely different computers), you can copy those song files as easily as any other file. You can even burn them to an unlimited number of CDs as standard CD AIFF files, which has the side effect of removing all playing restrictions.

    So just use your normal backup software to store a copy of your iTunes music library on a CD or whatever and your music should be as safe as you want it to be.

    I know this doesn't help you but I have found your situation to be very, very rare with Apple. I have had to get a few things fixed over many years of working with Macs and have never had this type of problems out of the box or with their customer service.

Two of those were laptops and I simply called Apple, got the problem verified, they sent out a mailer and I shipped it out to them. Three days later (one day out there, one day there, one day back) the laptops were back in my hands, fully fixed and they even had some other minor issues fixed that I didn't send them in for.

    For the two desktop units and the laser printer I brought them into a local service center. They took a couple of days to get repaired but they came back in perfect shape with the problems fixed. Throughout the whole process everyone was helpful and easy to deal with.

Again, it probably doesn't matter to you now and it doesn't help you much to know this. I would say that you should pass your experience on to someone higher up in the Apple food chain, maybe they can make things right.
