Beautiful Code is a collection of essays from some well known software engineers. That said, I didn't immediately recognize many of their names (this is probably an indication of my lack of exposure in their fields of expertise). If you are like me, there is an alphabetical list of short biographical entries in the back of the book you can use to acquaint yourself with who wrote each chapter.

There are chapters from people in the Perl, Python, Ruby, Google, Scheme, and Haskell communities (among others).

I especially enjoyed reading about Google's MapReduce algorithm, Haskell's Software Transactional Memory, and Scheme's syntax-case macro system. These are subjects I have previously tried to tackle, but the explanations written in this book have helped me approach understanding far better than the academic papers on these subjects I have tried to read.

You'll have to put forth effort to follow the explanations in the chapters as the authors walk you through how they tackle a given problem. This leads eventually to the solution, but may involve many twists and turns along the way. These twists and turns show how the authors think and grants us as the readers insight into how they approach the problems at hand. It's the journey to the desination that sometimes matters more than the destination.

For example, I've long wondered abut the difference between hygenic and non-hygenic macros. Various descriptions on the web have given me some clue, but chapter 25 shows examples and explains the problem very clearly. It then goes about discussing various solutions that have been devised over the years before going into the details of the current solution that is in use today. I've seen the end result before, but knowing what motivated the solution gives me a much greater appreciation for and understanding of it.

The effort required for some chapters may be over your head as they are for me, but those are the chapters where I find the rewards to be the greatest as they force me to look at things in new ways. Once I do achieve understanding I'm able to apply the new found ways of thinking about problems to the situations I face at work and elsewhere which has led to unique and compelling solutions that I would not have thought of before.

I've long been on the search for beauty in the code I write. I have found that as I read and take the time to understand what others see as beautiful, even when I do not see beauty in it at first, I gain greater insights into my craft. I am glad that O'Reilly has taken the time to solicit responses from the authors in this book as it has given us a wealth of experience and expertise that we all can benefit from as we seek to gain greater insights into the various facets of beauty and elegance in code.
