This Bob Glass book is a real "closet classic" of software literature, and one that deserves to be back in print. Originally published in 1990 or so, it's composed of technology-agnostic essays that cut right to the heart of development concerns. As with so many other classic programming books (Brooks' "Mythical Man-Month", Yourdon's "Death March", Weinberg's "Understanding the Professional Programmer", and McConnell's "After the Gold Rush" all leap to mind) the insights it contains remain relevant years after original publication. An added bonus is that this revised edition not only contains all the original material, but adds the author's retrospective opinions to each group of essays.
While most developers stick blindly to purely technical reading (if they do any outside reading at all), books like this are where the real thought-provoking ideas are. Covering topics like the benefits of reuse, the link between quality and maintenance, various flavors of project management, and more (there are a total of 60 short essays in the book), there is more than enough food for thought here for any software pro.
If you only do technology-specific reading, you owe it to yourself and your career to broaden your perspective. This is a great book for that. And if you already read general interest software books, don't miss this one. Great stuff.
