You don’t need elaborate hardware to start writing webbots. If you have a secondhand computer, you probably have the minimum requirement to play with all the examples in this book. Any of the following hardware is appropriate for using the examples and information in this book:
A personal computer that uses a Windows XP, Windows Vista, or Windows 7 operating system
Any reasonably modern Linux-, Unix-, or FreeBSD-based computer
A Macintosh running OS X (or later)
It will also prove useful to have ample storage. This is particularly true if your plan is to write spiders, self-directed webbots, which can consume all available resources (especially hard drives) if they are allowed to download too many files.
