Security on Rails

Security on Rails

Product Description

The advantage of using Rails is its agility; it makes developing your web applications easy and fast. The disadvantage is that it can leave holes in your security if you are not aware of common vulnerabilities. It’s a nerve-wracking and unfortunate fact that there are plenty of malicious people lurking on the Web. As a Rails developer, it is essential that you understand how to assess risk and protect your data and your users.
Security on Rails uses established security principles to teach you how to write more secure software, defend your applications from common threats, and encrypt your data. We’ll give you an example of a hacking exploit, and explore how to fix the weaknesses in an application.

You’ll learn the steps you need to take to control access to information and authenticate users, including cryptography concepts and authorization. In addition, you’ll see how to integrate your applications with external management systems; in short, the crucial details you must consider to protect yourself and your data.

The most important element of security is to plan for it before it becomes an issue. Security on Rails helps beginner and intermediate developers to take control of their applications and guard against attacks.

Google Web Toolkit: GWT Java AJAX Programming

Google Web Toolkit: GWT Java AJAX Programming

GWT (Google Web Toolkit) is an open source Java software development framework that makes writing AJAX applications like Google Maps and Gmail easy for developers who don’t speak browser quirks as a second language. Writing dynamic web applications today is a tedious and error-prone process; you spend 90% of your time working around subtle incompatibilities between web browsers and platforms, and JavaScript’s lack of modularity makes sharing, testing, and reusing AJAX components difficult and fragile.GWT lets you avoid many of these headaches while offering your users the same dynamic, standards-compliant experience. You write your front end in the Java programming language, and the GWT compiler converts your Java classes to browser-compliant JavaScript and HTML.

Domain-Driven Design Using Naked Objects

Posted: 21 Dec 2009 03:34 PM PST

Domain-Driven Design Using Naked Objects

Product Description

Domain-driven design (DDD) focuses on what matters in enterprise applications: the core business domain. Using object-oriented principles, you can develop a domain model that all team members-including business experts and technical specialists-can understand. Even better, this model is directly related to the underlying implementation.
But if you’ve tried building a domain-driven application then you’ll know that applying the DDD principles is easier said than done. Naked Objects, an open-source Java framework, lets you build working applications simply by writing the core domain classes. Naked Objects automatically renders your domain object in a generic viewer–either rich client or HTML. You can use its integration with Fitnesse to test-drive the development of your application, story-by-story. And once developed, you can deploy your application either to the full Naked Objects runtime, or within your existing application infrastructure.

In this book, Dan Haywood first gives you the tools to represent your domain as plain old Java objects, expressing business rules both declaratively and imperatively. Next, you’ll learn the techniques to deepen your design while keeping it maintainable as the scope of your application grows. Finally, you’ll walk through the development practices needed to implement your domain applications, taking in testing, deployment, and extending Naked Objects itself. Throughout the book, you’ll build a complete sample application, learning key DDD principles as you work through the application step by step. Every chapter ends with exercises to gain further experience in your own projects.

Through its focus on the core business domain, DDD delivers value to your business stakeholders, and Naked Objects makes using DDD easy to accomplish. Using Naked Objects, you’ll be ready in no time to build fully featured domain-driven applications.

A SAS/IML Companion for Linear Models (Statistics and Computing)

Posted: 21 Dec 2009 03:32 PM PST

A SAS/IML Companion for Linear Models (Statistics and Computing)

Product Description

Linear models courses are often presented as either theoretical or applied. Consequently, students may find themselves either proving theorems or using high-level procedures like PROC GLM to analyze data. There exists a gap between the derivation of formulas and analyses that hide these formulas behind attractive user interfaces. This book bridges that gap, demonstrating theory put into practice.

Concepts presented in a theoretical linear models course are often trivialized in applied linear models courses by the facility of high-level SAS procedures like PROC MIXED and PROC REG that require the user to provide a few options and statements and in return produce vast amounts of output. This book uses PROC IML to show how analytic linear models formulas can be typed directly into PROC IML, as they were presented in the linear models course, and solved using data. This helps students see the link between theory and application. This also assists researchers in developing new methodologies in the area of linear models.

The book contains complete examples of SAS code for many of the computations relevant to a linear models course. However, the SAS code in these examples automates the analytic formulas. The code for high-level procedures like PROC MIXED is also included for side-by-side comparison. The book computes basic descriptive statistics, matrix algebra, matrix decomposition, likelihood maximization, non-linear optimization, etc. in a format conducive to a linear models or a special topics course.

Also included in the book is an example of a basic analysis of a linear mixed model using restricted maximum likelihood estimation (REML). The example demonstrates tests for fixed effects, estimates of linear functions, and contrasts. The example starts by showing the steps for analyzing the data using PROC IML and then provides the analysis using PROC MIXED. This allows students to follow the process that lead to the output.
