As noted in

an eBook version does exist at this moment so discussion can properly move to the 4th edition forum at this point.

I just bought the kindle version of 4th Edition. Could you tell me where to download the sample code in the book? Please email hmartel@syr.edu as I don’t log in the forum often.
Thanks much
