Redundancy

To Those Who Use Flash mp3 Players

If you want people to listen to an mp3 or some other audio format, but need to hide it so that it can't be downloaded, don't do it like this:

From this data taken from a packet sniffer, it is fairly easy to see that the flash player (from here) is accessing the url http://blogs.okayplayer.com/audio/one-day-as-a-lion-wild_international.mp3

Fall 2008 Books

These, apparently, are the books for my classes I'm taking this coming semester:

Principles of Modern Operating Systems
Haskell School of Expression
Piano for the Developing Musician
Chemistry in Your Life
Puntos de partida
Puntos de partida : Workbook
Puntos de partida : Laboratory Manual

Here is a breakdown of the cost of each book compared to my school's and to amazon.com (who is usually the least expensive)


* - Lowest price was actually about $25.00, but it it was supposed to have been in fairly terrible condition, so I went the next cheapest, which is actually on par with the price of other used copies of this book.
** - I think I already own this book.

Also another note, where the price was N/A the price for the book that was available was substituted (i.e. where the new version of the book was not available, the price of the used one was substituted). Also, shipping on the Amazon.com books will be at least $4 a piece, which still makes buying from them much more sensible than the school's bookstore.


As you can see, I can spend as much as $605.99 or as little as $190.81. Which option do you think that my broke college student self is going to go with? The used option that isn't from my school's bookstore of course.
