Code: And Other Laws of Cyberspace, Version 2.0 ReviewYou can download this book at no charge in pdf format from Lessig's site.Code: And Other Laws of Cyberspace, Version 2.0 OverviewThere's a common belief that cyberspace cannot be regulated-that it is, in its very essence, immune from the government's (or anyone else's) control. Code, first published in 2000, argues that this belief is wrong. It is not in the nature of cyberspace to be unregulable; cyberspace has no "nature." It only has code-the software and hardware that make cyberspace what it is. That code can create a place of freedom-as the original architecture of the Net did-or a place of oppressive control. Under the influence of commerce, cyberspace is becoming a highly regulable space, where behavior is much more tightly controlled than in real space. But that's not inevitable either. We can-we must-choose what kind of cyberspace we want and what freedoms we will guarantee. These choices are all about architecture: about what kind of code will govern cyberspace, and who will control it. In this realm, code is the most significant form of law, and it is up to lawyers, policymakers, and especially citizens to decide what values that code embodies. Since its original publication, this seminal book has earned the status of a minor classic. This second edition, or Version 2.0, has been prepared through the author's wiki, a web site that allows readers to edit the text, making this the first reader-edited revision of a popular book.

JavaScript and Ajax for the Web, Sixth Edition ReviewThe audience for this book is beginning/novice web developers with a knowledge of HTML but not of JavaScript. The book begins with an introduction to basic JavaScript language features and then proceeds to work through a number of examples according to category (images, frames, browser windows, forms, regular expressions and strings, user events, and cookies). After, there are two chapters on AJAX fundamentals.
The book does not claim to be an in-depth resource. The general purpose of the QuickStart series of books is to provide an overview of the main concepts and practices in use by web developers today. It is meant to be a STARTING POINT to introduce novices to technologies, not as an in-depth reference. The authors of this and other QuickStart books point this out continually, yet still get bad reviews from people who have not taken the time to read about the purposes of various series from technical publishers. This is unfortunate for the public as well as unfair to the authors.
A previous reviewer mentioned what he took to be atrocious coverage of Ajax. The book contains two chapters exclusively covering Ajax. The first covers the fundamental techniques used to take advantage of this combination of technologies. The second chapter explores some of the popular Ajax toolkits currently available. This is consistent with the purpose of the book. Some readers may be interested in heading down the development path, yet others may be more interested in design and in using pre-existing tools. This book caters to both and has no intention of deceiving either reader.
The following quote is a good example of this. It is an excerpt from the title page of Chapter 16, which follows the introductory chapter (basic XMLHttpRequest usage, etc.) and precedes the Ajax toolkit chapter:
"[Writing] Ajax applications can be difficult. They often require a great deal of knowledge of working with the DOM, CSS, JavaScript, and server resources. Since this is a book for beginning scripters, we've shown you how to do some easy things with Ajax, so you can see that learning Ajax techniques is well within your reach. But many books have been written that are completely devoted to showing intermediate-to-advanced scripters how to create Ajax applications, and our Ajax chapters are no substitute for that kind of in-depth exploration."
As for the dual-column formatting that some reviewers disliked, it is consistent with the formatting of the entire QuickStart series, as well as the QuickPro series of the same publisher. The format is nice for tackling specific techniques in a concise amount of space. It is not as abstractly engaging as conventional technical books, but it is not meant to be. The format is excellent for explaining techniques (especial design techniques) as well as for conveying a sense of quick forward momentum.
I've only recently started reading books from Peachpit Press. I like these books because they get me up to speed quickly, and act as a comprehensive starting point, allowing me to understand "where I need to go from here."
This book is excellent as a broad introduction with lots of real-world examples. If you're a novice web developer with a decent grasp of HTML wishing for a comprehensive introduction to JavaScript and practical JavaScript techniques, this is the book for you.
However, if you're well-grounded and are looking for more in-depth coverage of JavaScript and Ajax techniques, "Professional JavaScript for Web Developers" (Nicholas Zakas / Wrox Press) and "Professional Ajax" (Zakas, et. al. / Wrox Press) are excellent in-depth resources geared toward real-world professional development, and both are among the best peer-reviewed titles in existence on these subjects.JavaScript and Ajax for the Web, Sixth Edition Overview

Codin' for the Web: A Designer's Guide to Developing Dynamic Web Sites ReviewEvery time you buy a computer-related book, you hope that it is going to be THE one that ties it all together for you - answers all your questions, and leaves you thinking that with this book alone, I'm going to understand and be able to actually DO what I'm wanting to get done. Like me, if you are the frequent buyer of computer books, you know that we purchase each book with this eternal optimism, only to be let down every single time. Not any more: THIS BOOK TRULY IS WHAT YOU'RE HOPING TO BUY!
The author not only understands the subject, but more than any other author I've ever read, he truly seems to have the geek-free comprehension of what his audience is wanting to get from the book. This isn't even meat and potatoes - It's meat only! Other books will touch on every important issue, but always with the caveat of "a detailed discussion is beyond the scope of this book".
SO WHO'S THE PERFECT AUDIENCE FOR THIS BOOK, AND WHAT IS IT GOING TO CONVEY SO WELL?
This book is perfect for all of those readers who have a little bit of exposure to javascript, php, XHTML, and CSS, probably gained from a frustrated, partial reading of other books, all originally read because you want to truly understand what it takes to put up a high-quality, interactive web site from scratch. This book is going to show you (really!!) how to do that!
The chapters are:
1) Coding Principles
2) Processing Forms
3) Databases
4) Content Management
5) Cookies and Authentication
6) Building A Website With PHP
Two online bonus chapters are:
A) Unleashing the Geek Within
B) Coding the Interface
More than any other tech book I've ever read, with this book, it is as if the author sat down with you and said,
"Okay, I'm going to take the next few days to really show you, from scratch, what I do to get a client's business on the web. I'm not going to try to impress you or confuse you so that you'll think I'm smart. I'm going to show you what I do, step by step, from beginning to end. I'll be thorough, but we don't have any time to waste."
AFTER ALL, ISN'T THAT WHAT WE ALL WANT WHEN WE BUY A COMPUTER BOOK?!
I own an online educational site for professionals, and I have paid a professional PHP programmer about $8,000 this last year to bring it up to where it is at the rate of $100 per hour. I AM TRULY FEELING LIKE, AFTER READING THIS BOOK, THAT I COULD HAVE DONE VIRTUALLY ALL OF IT MYSELF!
What a masterpiece! I can't recommend it highly enough!Codin' for the Web: A Designer's Guide to Developing Dynamic Web Sites OverviewEVEN THE MOST SKILLED WEB DESIGNERS can find the complexities ofcreating a full-functioned Web site to be a daunting task. Here to helpdesigners create sites that not only work, but work well and are easyto update and maintain is an easy-to-read guide to Web programmingbasics from best-selling author Charles Wyke-Smith. Just as architectsneed to understand building materials and their properties, Webdesigners need to understand the code that serves as the foundation oftheir sites. Wyke-Smith ensures they do by teaching designers that alldynamic Web sites consist of essentially three components: a browserinterface, Web server middleware, and a database. The guide coverseverything from Web coding concepts and principles to building sites,designing visual interfaces, developing databases, developingmiddleware, ensuring a good user experience (through good code!),testing and debugging, and more.
Create dynamic Web sites that provide real-time responses to user inputs

Understand the basic structures of all coding languages, such as variables, functions, conditionals, loops, and objects

Use the power of PHP to program the business rules of your site

Learn techniques for validating forms to reject erroneous or malicious data

Import and export data from other applications via at les

Build and query database tables using SQL to manage the data generated by your site's activity

Develop a simple content management system

High Performance JavaScript (Build Faster Web Application Interfaces) ReviewThis book is a good reference on how to optimize JavaScript applications and also an interesting read in case you want to know how things work "under the hood".
Many of the techniques presented also works for other programming languages (and are well-known performance tricks) and can be used without increasing too much the code complexity, which is a huge gain, you're not just becoming a better JavaScript developer but also a better developer.
One thing that should be clear is that this book is NOT intended for BEGINNERS, since it already presumes that you have a good knowledge and experience with JS programming.
If you already read Professional JavaScript for Web Developers (Wrox Programmer to Programmer) (also written by Zakas), High Performance Web Sites: Essential Knowledge for Front-End Engineers and Even Faster Web Sites: Performance Best Practices for Web Developers you will find that some of the techniques were already present on those books, so if you're up-to-date with the new technologies/tools and been researching about the subject probably you already know a good part of what this book has to teach, nevertheless it still a nice and interesting read since it explains how the JavaScript engines work and why those techniques are faster, the fact that it is concise is a big plus too.
The book has some typo mistakes (which doesn't affect the understanding) and some of the line graphs (used to show browsers benchmark) are hard to read since all the lines look the same (as of 1st Edition).
I strongly recommend this book to any intermediate to advanced developer who wants to learn how to improve the overall performance of JavaScript applications since it is a concise and accurate compilation of best practices, even if you know a lot about the subject you may learn a few new tricks or understand a little bit better why it works...High Performance JavaScript (Build Faster Web Application Interfaces) Overview
If you're like most developers, you rely heavily on JavaScript to build interactive and quick-responding web applications. The problem is that all of those lines of JavaScript code can slow down your apps. This book reveals techniques and strategies to help you eliminate performance bottlenecks during development. You'll learn how to improve execution time, downloading, interaction with the DOM, page life cycle, and more.

Yahoo! frontend engineer Nicholas C. Zakas and five other JavaScript experts -- Ross Harmes, Julien Lecomte, Steven Levithan, Stoyan Stefanov, and Matt Sweeney -- demonstrate optimal ways to load code onto a page, and offer programming tips to help your JavaScript run as efficiently and quickly as possible. You'll learn the best practices to build and deploy your files to a production environment, and tools that can help you find problems once your site goes live.

Identify problem code and use faster alternatives to accomplish the same task
Improve scripts by learning how JavaScript stores and accesses data
Implement JavaScript code so that it doesn't slow down interaction with the DOM
Use optimization techniques to improve runtime performance
Learn ways to ensure the UI is responsive at all times
Achieve faster client-server communication
Use a build system to minify files, and HTTP compression to deliver them to the browser
