Researchers at the California Institute of Technology have developed a "microscope on a chip" that is small and can be produced very inexpensively. The Science daily, July 29, 2008 claims that it can be mass-produced at around $10.

Because this device is small, has no lens to break, and can be produced at low cost the potential applications for this new microscope are exciting. You could, for instance, develop a microscope that could fit in a cell phone sized devide. Such a device would, amoung other things, help field workers in undeveloped countries to check for malaria or for hikers to check for microbes.

Originally this article was supposed to be a book review of the upcoming O'Reilly title Subject to Change, but I was so appalled by its content that I felt compelled to shift focus to the more important issue of ethics in publishing. This book reflects a sinister trend in the tech book publishing industry that favors vapid, tedious material that serves to advise readers without revealing the big secrets. The purpose is for the authors (usually a group of writers, and most of them high-level managers) to promote their company and its services by giving readers just enough information. If they want the advanced material, they need to buy the rest at a premium price by going straight to the company for its professional services. Meanwhile, the publisher bathes in a sea of money while the authors relentlessly promote the book on their blogs and in their conference keynotes and panel discussions. Tech books have increasingly become corporate marketing vehicles, sacrificing the exciting A-list technical material that regular tech book buyers and enthusiasts have come to expect from companies like O'Reilly Media and Pearson Education. This isn't the first book I've seen that gives readers a 20,000-word marketing pitch -- that honor belongs to Enterprise Ajax (and it's about three times longer). I'm bothered -- sickened -- to see that not only is this trend continuing unabated, but it's actually become a habit.

Web navigation is, ideally, something you never have to think about as a Web site visitor or user. As a Web designer, however, it is among your primary concerns. If you need a good education on this particular subject, you'll find a great resource in O'Reilly's Designing Web Navigation. It's an outstanding guide to building effective, professional navigation for sites of all kinds.

There aren't many FreeBSD books on the market -- compared to the number of Linux books, anyway -- so it's important that the few extant titles be superbly written and technically accurate. I was really looking forward to reading Absolute FreeBSD 2nd Edition because I'd heard such great things about the aged first edition. Unfortunately, I found this book to be a spectacular disappointment.

In switching over our software and hardware review sites to a new publishing application, site design is something we put a lot of consideration into. I wish I'd had The Principles of Beautiful Web Design to read as I was going through that process. Content-wise, it is indeed that good -- it's indispensable for Web designers, professional and amateur. It's afflicted by substandard editing, but the high-color, graphic-rich, information-heavy content is superb.

Ah, yet another book about Ubuntu Linux. Is there no reprieve from the bombardment of Ubuntu and beginner Linux books (and Ubuntu for beginners books)? For Introducing Ubuntu: Desktop Linux to impress me, it had to offer something new and unique, and it had to successfully address the reality of introducing a new operating system to a computer user. I'm impressed with the scope of the book's coverage on frequently encountered Linux problems, but I don't think this book was as good as it could have been.

Innovation is word roughly as over-used in the information technology industry as change is in politics. Everyone talks about it, but few people actually implement it beyond a superficial level. It's a buzzword; it was the first term in the marketingspeak canon; it's what CEOs talk about when they don't have a crisis to manage. When I first got The Myths of Innovation in for review, I was intrigued by the first parts of it I read, so I interviewed the author, Scott Berkun and asked him some questions about innovation as it relates to open source software. It turns out that innovation can move beyond marketingspeak and ridiculous Steve Ballmer speeches and actually represent invention and improvement. The Myths of Innovation showcases a wide variety of useful ideas, processes, and methods that smart people can use to succeed as inventors, engineers, and managers. As the title implies, there is also a lot of talk about what not to do when trying to think of new ways to succeed. This is a truly inspiring book.
