Programming Ruby 1.9: The Pragmatic Programmers' Guide (Facets of Ruby)

By Dave Thomas, Chad Fowler

Would you love to move from first suggestion to operating code a lot, a lot quicker? Do you now spend extra time pleasant the compiler rather than your consumers or finish clients?

The Practice of Network Security Monitoring: Understanding Incident Detection and Response

By Richard Bejtlich

Network defense isn't easily approximately construction impenetrable partitions — decided attackers will finally conquer conventional defenses. the simplest computing device protection recommendations combine community defense tracking (NSM): the gathering and research of knowledge that can assist you realize and reply to intrusions.
