C++ coding standards : 101 rules, guidelines, and best practices / Herb Sutter, Andrei Alexandrescu. Addison-Wesley, 2005
Such a simple yet invaluable book to anyone coding in C++, because code readability is so important. Lend it to co-workers and hope they read it.
The recommended standards are practical, and after you have read this book you will see them as common-sense. Each is supported by references to well known authorities.
Security engineering : a guide to building dependable distributed systems / Ross J. Anderson. Wiley 2008, hard cover
1000 very readable pages of straight talk on security. This affects almost everyone. The first edition was published in 2001, and the book appears to have been rewritten. I wish there was a new edition yearly.
According to B. Schneier, “It’s beautiful. This is the best book on the topic there is”.
Silence on the wire : a field guide to passive reconnaissance and indirect attacks by Michal Zalewski. No Starch Press, 2005
This book on internet security is much different than most. Firstly, it is a joy to read! It has no dry descriptions of the latest vulnerabilities, but instead it delves into the technologies that underlie the Internet, and explores their inherent limitations.
Professional Python frameworks : Web 2.0 programming with Django and TurboGears / Dana Moore, Raymond Budd, William Wright.
If you are developing web applications using Python you will want to use a framework so you are not re-implementing all the ‘glue’ that is common to all web apps and so you have a clear project structure to work around. This book is an excellent introduction to two frameworks, TurboGears and Django.
