Amazon.com gives out for free the first chapter of the Kindle version of Effective Perl Programming. The “first chapter” includes the front matter and up to half way through Item 6 in “The Basics of Perl”.
There’s a Kindle application for most devices, including Android (anyone want to send an Android screenshot to go with our other screenshots)? On my iPhone, the rotation is locked for some reason (other apps rotate just fine) and the code font is very small. On the iPad it looks okay.
I didn’t see the other Amazon.com sites giving out Kindle sample chapters.
Also, you can also read our “Files and Filehandles” chapter for free.
