Urgent warning about the Net Pal spyware Trojan!

Share Your Opinions: Please take the new HSP survey

If you've ever used “sniping” software or FFA-posting software, you have some idea of the power behind being able to write your own robots. The possibilities are endless: tracking stocks, entering contests, finding people, etc. You might even find that running a spider can keep your ISP from logging you out!

In this book, I share what I've learned over the past 3 years and show you how to put it all together with some sample programs — including a “sniper” that still works (as of this writing)! [WARNING: Sniping software is no longer tolerated on eBay^TM!]

The book features the following sections:

Sockets
What they are and how to work with them
URL Encoding
and the format of HEAD, GET, and POST queries
Perl for the Masochist and the Underprivileged
both for writing spiders and for maintaining your cgi-bin
Putting It All Together!
A sample spider program
A Bonus Robot - The Sniper
Here's a robot you can use for last-minute bidding!
Bibliography
Unfortunately, the best one's out-of-print!

Testimonial:
Hello, Jerry.  I'm honored to be the first person to purchase your
book.  I've been slowly digesting the material for the last couple of weeks
and am finding it to be very clear and straight forward in it's
presentation.  Sorry.  No constructive critisism here.  The text was very
well written with plenty of illustrations.  Has anyone else purchased the
book?  What did they have to say about it?  I guess it's going to depend
greatly on the person's level of technical experience as to how helpful they
find this text.

Thanks,
