Search Patterns: Design for Discovery Review"There's no shortage of problems with search today," says Peter Morville at the end of Search Patterns, his most recent book. Throughout the book, Morville chronicles the challenges of search and effectively communicates the best practices of building usable search experiences. While the book more than adequately accomplishes it's stated goal -- to foster greater cross-disciplinary collaboration by increasing search literacy -- it would have been an even better book if the author had proposed more of his own innovative solutions to search's problems.
In the preface Morville sets out to tear down the walls between disciplines, and at this he succeeds. From user psychology to technical considerations to the specific components of the user interface, Search Patterns has something for everyone involved in implementing search.
The first two chapters lay the groundwork for the rest of the book, discussing both why people search and the individual components that make up search. The book is in full swing by chapter three where Morville discusses user behavior, elements of interaction, and -- my personal favourite -- the principles of design.
In talking about design principles, Morville describes search both as a conversation and a jazz-like improvisation. He urges the architect to make search an easy, simple process to initiate, followed by a progressively more sophisticated toolkit that enables users to iteratively refine their query. He argues for a no-suprises approach to the user interface in which valuable options are highly visible and elements of interaction are easily predictable. Many of the principles are applicable to a much broader context than search alone, but that only stregthens their merit.
The real heart of the book is chapter four, which looks at 10 design patterns over 50 pages. It considers the obvious patterns -- autocomplete, faceted navigation, advanced search -- as well as more disparate groupings like federated search and personalization. I was disappointed that the patterns only summarised existing conventions rather than challenging any bad habits. And while this chapter does consume 30% of the book by page count, it manages to stay at a very high level, even to a fault. I would have preferred more permutations and analysis of the cornerstone patterns, such as faceted navigation, while spinning some of the less well-defined patterns into chapters of their own for more consideration.
However, the lack of innovative solutions or granular analysis is quelled by the wealth of thought-provoking examples throughout the book, with an especially high concentration of desktop, mobile, and even kiosk visuals in chapter five.
The final chapter of the book is a forward-looking vision of what search could look like in the distant future, as well as what it probably won't look like (sorry, no "knowledge navigator" robot assistants). While an enjoyable thought exercise, I would have preferred more concrete insights into the near-future possibilities for search (collaborative, task-oriented searching, for example).
Despite a lack of new ideas, Search Patterns is a must-read for everyone collaborating on a search application. It will give your team of designers, engineers, and business stakeholders a common vocabularly and greater awareness of the many sides of search.
Morville ends the book -- as I will end this review -- by urging the reader to get to work on making search better: "For every unsolved problem," he says, "there are countless instances in which we know the solution, but nobody has bothered to implement it. Discipline and attention to detail would go a long way toward improving the world of search."
You should get started by reading this book.Search Patterns: Design for Discovery OverviewSearch is among the most disruptive innovations of our time. It influences what we buy and where we go. It shapes how we learn and what we believe. In this provocative and inspiring book, you'll explore design patterns that apply across the categories of web, ecommerce, enterprise, desktop, mobile, social, and real-time search and discovery.

Head First jQuery ReviewIt might sound strange, but first thing I am grateful to Ryan and Ronan is mentioning TextWrangler in the beginning of the book. This way I got familiar with very simple, useful, and free (free as in free beer) editor for Mac OS
I haven't used jQuery before, and I wanted to see what it is all about. First of all, I like to learn by examples - and you got them here. All in one piece - zipped - directly on your hard drive from the Head First Lab web page (each example contains corresponding jQuery library). This is nice. You simply don't have to copy-paste everything you see in the book into your text editor. When it comes to the content. Well, this is always hard thing to judge. I know people who hate Head First series. They say it is not sophisticated enough. I am, on the contrary, a great fan of Head First. jQuery, like any other Head First series book, gives you simple, straight overview of the topic. OK, it will not provide you with as much text as other books, but hey, "A picture is worth a thousand words". And you will find lots of them here. However, if you consider yourself a hacker, don't buy it. It's rather for beginners. If you are a beginner - I'd consider buying it.Head First jQuery Overview
Want to add more interactivity and polish to your websites? Discover how jQuery can help you build complex scripting functionality in just a few lines of code. With Head First jQuery, you'll quickly get up to speed on this amazing JavaScript library by learning how to navigate HTML documents while handling events, effects, callbacks, and animations. By the time you've completed the book, you'll be incorporating Ajax apps, working seamlessly with HTML and CSS, and handling data with PHP, MySQL and JSON.

If you want to learn—and understand—how to create interactive web pages, unobtrusive script, and cool animations that don't kill your browser, this book is for you.

Python Web Development with Django ReviewWe are a Python shop at work and have recently started developing in Django. So I picked this book up as a total beginner to Django, but an experienced Python programmer. I feel that the book would be more or less the same even for someone totally new to Python, because Django is definitely a different kind of beast.
Overall, this book was okay to good. I would give it 3.5 stars if I could. It is definitely targeted at beginners to Django (and possibly Python). As a Django beginner, I first ran through the tutorial on the Django website, because it is very thorough and good. I definitely recommend that as a starting place regardless of which book you end up buying. Then I cracked open this book. The first chapter is a 50-page introduction to Python, so I skipped that. Chapter 2 is a tutorial in which you build a simple blog. So by the time I had finished that chapter, I had built two different Django sites but not really read anything about the language or framework or theory thereof. I think this is a good thing, and this chapter is well-placed. Chapter 3 introduces Django. It covers dynamic web sites, communication, data storage, presentation, separating the layers (MVC), general django architecture, and "core philosophies of Django". It is a decent introduction, though I read through it quickly so I could get to the next three chapters.
The next three chapters make up the Django in Depth section and are the bread-and-butter of the book. The first chapter covers models, the second URLs/HTTP/views, and the third templates and form processing. For me, these were the chapters I was most looking forward to, where I would learn everything I needed to know to get started really understanding. And they let me down a bit. Each one was good in what it covered, but the problem was that it left out quite a bit. The part on the models themselves was pretty good and covered the necessities. But the part on querying was a little sparse. They left much for the reader to go to the documentation and find out. (But what's the point of the book, then?) I did think it was nice that they mentioned fixtures, as I had trouble finding that information online when I needed to set one up for work. The chapter on views was decent, but seemed to leave out too much detail. The section covering views specifically was short. Finally, the template/forms chapter again left the reader to find out critical details in the online documentation. First, the template section was short. Second, the forms section seemed long enough, but I just found that it wasn't that helpful when I was really creating forms for work.
The next four chapters are tutorials in which you build various applications. I haven't gone through these yet, but they look pretty good. I think Django is one of those things that is best learned in a very hands-on fashion. Perhaps some of the weaknesses of the previous three chapters are made up for here; but I doubt it, and if so feel that information should have still been included in the earlier chapters. (The book is fairly slim and could definitely be expanded.) Chapter 11 covers advanced Django programming, including customizing the admin, using syndication, generating downloadable files, enhancing Django's ORM with custom managers, and extending the template system. The chapter seems decent enough, although I haven't had to do any of these things yet. Likewise, with Chapter 12 covering advanced Django deployment, I haven't had to deploy anything yet so I only know that the chapter seems to cover some useful information.Python Web Development with Django OverviewUsing the simple, robust, Python-based Django framework, you can build powerful Web solutions with remarkably few lines of code. In Python Web Development with Django®, three experienced Django and Python developers cover all the techniques, tools, and concepts you need to make the most of Django 1.0, including all the major features of the new release. The authors teach Django through in-depth explanations, plus provide extensive sample code supported with images and line-by-line explanations. You'll discover how Django leverages Python's development speed and flexibility to help you solve a wide spectrum of Web development problems and learn Django best practices covered nowhere else. You'll build your first Django application in just minutes and deepen your real-world skills through start-to-finish application projects includingSimple Web log (blog) Online photo gallery Simple content management system Ajax-powered live blogger Online source code sharing/syntax highlighting tool How to run your Django applications on the Google App EngineThis complete guide starts by introducing Python, Django, and Web development concepts, then dives into the Django framework, providing a deep understanding of its major components (models, views, templates), and how they come together to form complete Web applications. After a discussion of four independent working Django applications, coverage turns to advanced topics, such as caching, extending the template system, syndication, admin customization, and testing. Valuable reference appendices cover using the command-line, installing and configuring Django, development tools, exploring existing Django applications, the Google App Engine, and how to get more involved with the Django community.Introduction 1Part I: Getting StartedChapter 1: Practical Python for Django 7Chapter 2: Django for the Impatient: Building a Blog 57Chapter 3: Starting Out 77Part II: Django in DepthChapter 4: Defining and Using Models 89Chapter 5: URLs, HTTP Mechanisms, and Views 117Chapter 6: Templates and Form Processing 135Part III: Django Applications by ExampleChapter 7: Photo Gallery 159Chapter 8: Content Management System 181Chapter 9: Liveblog 205Chapter 10: Pastebin 221Part IV: Advanced Django Techniques and FeaturesChapter 11: Advanced Django Programming 235Chapter 12: Advanced Django Deployment 261Part V: AppendicesAppendix A: Command Line Basics 285Appendix B: Installing and Running Django 295Appendix C: Tools for Practical Django Development 313Appendix D: Finding, Evaluating, and Using Django Applications 321Appendix E: Django on the Google App Engine 325Appendix F: Getting Involved in the Django Project 337Index 339Colophon 375
