Microsoft Content Management Server 2002 is a dynamic web publishing system with which you can build websites quickly and cost-efficiently. MCMS provides the administration, authoring, and data management functionality, and you provide the website interface, logic, and workflow. Once your website is up and running, your content contributors can add and edit content on their own, without the need to work with developers or the IT department. First time developers of Microsoft Content Management Server 2002 face a relatively steep learning curve. Not only are they expected to be conversant in the Microsoft .NET Framework, they are also required to be familiar with the concepts of MCMS 2002. Many beginners to MCMS start out by looking at the example site that ships with the product; tweaking it, dissecting it and turning it inside out using the obscure code comments as markers. However, when it comes to starting their own website from scratch, many are baffled ? where do they begin? This book exists to answer that question; teaching the essential concepts of MCMS 2002 in a clear, straightforward and practical manner. Containing answers to some of the most asked questions in developer newsgroups, this book is a treasure trove of tricks and tips for solving the problems faced by MCMS developers. This is a unique resource focused exclusively on the needs of developers using MCMS. It doesn?t waste time and pages on user or administrator level information that is well covered in other documentation. It?s a distillation of practical experience that developers need to get results, fast. The authors carefully structured example project complements and extends the knowledge gained from an initial look at the examples that ship with MCMS.

Soar with Haskell. The ultimate beginners' guide to mastering functional programming from the ground up

Tom Schrijvers

With software systems reaching new levels of complexity and programmers aiming for the highest productivity levels, software developers and language designers are turning toward functional programming because of its powerful and mature abstraction mechanisms. This book will help you tap into this approach with Haskell, the programming language that has been leading the way in pure functional programming for over three decades.The book begins by helping you get to grips with basic functions and algebraic datatypes, and gradually adds abstraction mechanisms and other powerful language features. Next, you’ll explore recursion, formulate higher-order functions as reusable templates, and get the job done with laziness.
