The second edition was updated with leading-edge practices and hundreds of new code samples, illustrating the art and science of software construction. Capturing the body of knowledge available from research, academia, and everyday commercial practice, McConnell synthesizes the most effective techniques and must-know principles into clear, pragmatic guidance. No matter what your experience level, development environment, or project size, this book will inform and stimulate your thinking, and help you build the highest quality code.

Most programmers arrive at the so-called tricks of the trade over time, through independent experimentation. In The Pragmatic Programmer, Andrew Hunt and David Thomas codify many of the truths they've discovered during their respective careers as designers of software and writers of code.

The cool thing about this book is that it's great for keeping the programming process fresh. The book helps you to continue to grow and clearly comes from people who have been there. The authors' central philosophy is that programming is the task of breaking large problems into small ones. You will learn a thing or two about functional programming, lazy evaluation, metaprogramming well, metalinguistic abstraction , virtual machines, interpreters, and compilers.

The book was originally written for the famous 6. It may require an intellectual effort to read, but the reward is well worth the price. Co-written by Dennis Ritchie, the inventor of the C programming language. Introduction to Algorithms By Thomas H. Cormen , Charles E. Leiserson , Ronald L. Rivest and Clifford Stein Published: July 31, Publisher: The MIT Press Amazon Link: here Introduction to Algorithms, the 'bible' of the field, is a comprehensive textbook covering the full spectrum of modern algorithms: from the fastest algorithms and data structures to polynomial-time algorithms for seemingly intractable problems, from classical algorithms in graph theory to special algorithms for string matching, computational geometry, and number theory.

The revised third edition notably adds a chapter on van Emde Boas trees, one of the most useful data structures, and on multithreaded algorithms, a topic of increasing importance. It is the process of changing a software system in such a way that it does not alter the external behavior of the code, yet improves its internal structure.

With refactoring you can even take a bad design and rework it into a good one. For example, we struggled to find out where to change an application's Internet permissions, and when we found a window that displayed current permissions, the list featured impossibly cryptic filenames, such as evcreate. Diligent but bothersome Like other personal firewalls, BlackIce alerts you when an intruder attempts to access your system or when it notices suspicious Net activity coming from your PC the latter can indicate an active Trojan horse on your computer.

Version 3. But this protection proves annoying at times. BlackIce pops up a dialog box every time you install a new app or utility, even if the new program doesn't access the Net, and the first time that Web-related apps go online.

You can tell BlackIce to stop showing these dialogs, but we prefer Norton Internet Security's automatic-access configuration, which doesn't pester you each time. We ran tests found at ShieldsUp to probe for unprotected ports, and, as in the past, BlackIce left only one port visible to hackers. By contrast, ZoneAlarm and Norton stealth , or hide, all ports.

Sadly, BlackIce also lacks a tool that scans e-mail messages for suspicious attachments, such as macros or Visual Basic scripts, a favored format for viruses. Since all packets are processed by these products, this vulnerability can be exploited even when the utilities are set to their most restrictive settings. When these products receive an SMB packet, the packet is disassembled, processed and reassembled. The vulnerability occurs in the code that reassembles the SMB packet.

According to eEye's advisory , the following products are affected:. Exploitation of this vulnerability could lead to the execution of arbitrary code on the system with privileges of the vulnerable process, typically the "SYSTEM" user on the windows platform.

This vulnerability is resolved in BlackICE 3. As firewall. Http server ssl module common. Lotus domino. Tivoli management framework.
