"The first edition of Programming Pearls was one of the most influential books I read early in my career, and many of the insights I first encountered in that book stayed with me long after I read it. Jon has done a wonderful job of updating the material. I am very impressed at how fresh the new examples seem." --Steve McConnell When programmers list their favorite books, Jon Bentley's collection of programming pearls is commonly included among the classics. Just as natural pearls grow from grains of sand that irritate oysters, programming pearls have grown from real problems that have irritated real programmers. With origins beyond solid engineering, in the realm of insight and creativity, Bentley's pearls offer unique and clever solutions to those nagging problems. Illustrated by programs designed as much for fun as for instruction, the book is filled with lucid and witty descriptions of practical programming techniques and fundamental design principles. It is not at all surprising that Programming Pearls has been so highly valued by programmers at every level of experience.In this revision, the first in 14 years, Bentley has substantially updated his essays to reflect current programming methods and environments. In addition, there are three new essays on / testing, debugging, and timing / set representations / string problems All the original programs have been rewritten, and an equal amount of new code has been generated. Implementations of all the programs, in C or C++, are now available on the Web. What remains the same in this new edition is Bentley's focus on the hard core of programming problems and his delivery of workable solutions to those problems. Whether you are new to Bentley's classic or are revisiting his work for some fresh insight, the book is sure to make your own list of favorites. 0201657880B04062001

Free Programming Pearls
The thirteen columns in this book appeared in the Communications of the ACM between 1983 and 1985. There can't be more than a couple of technical books on computing from that era that are still worth reading. Kernighan & Ritchie's book, "The C Programming Language", is one that springs to mind; this book is definitely another, and will probably outlast K&R as it has almost no ties to existing or past hardware or languages.What Bentley does in each of these columns is take some part of the field of programming--something that every one of us will have run into at some point in our work--and dig underneath it to reveal the part of the problem that is permanent; that doesn't change from language to language. The first two parts cover problem definition, algorithms, data structures, program verification, and efficiency (performance, code tuning, space tuning); the third part applies the lessons to example pseudocode, looking at sorting, searching, heaps, and an example spellchecker.
Bentley writes clearly and enthusiastically, and the columns are a pleasure to read. But the reason so many people love this book is not for the style, it's for the substance--you can't read this book and not come away a better programmer. Inefficiency, clumsiness, inelegance and obscurity will offend you just a little more after you've read it.
It's hard to pick a favourite piece, but here's one nice example from the algorithm design column that shows how little the speed of your Pentium matters if you don't know what you're doing. Bentley presents a particular problem (the details don't matter) and multiple different ways to solve it, calculating the relationship between problem size and run time for each algorithm.
Without any doubt, my favorite article in _Communications of the ACM_ in the 1980's was the regular `Programming Pearls' articles by Jon Bentley. When the first edition of these collected gems was published, I read it with great delight. Now, over a decade later, a second edition has been published, containing the same problems with additional modifications and notations. Given the enormous changes in programming since the mid 80's, your first reaction might be that this book is dated and therefore irrelevant. Nothing could be further from the truth.
Elegant solutions to complex programming problems are free from the rot of time. Programming is a thought process largely independent of the notation used to write it down. The solutions are sketched and explained rather than coded, and the solutions are complete. There is a certain mystique about taking a complex problem, finding an initial solution and then refining it down until it kicks some big time. There are some major lessons in program refinement explained in these solutions.
Coding a binary search is covered quite extensively, which may seem like a waste of space, as this problem was solved decades ago. However, that solution took decades to get right, and this is one of those "separates the coders from the key bangers" type of problem. Other problems examined include performance tuning, squeezing space and program correctness. While the improvement in the performance of the hardware has been astounding since these solutions were written, that does not make them obsolete. The complexity of the programs that we now build has risen even faster, so performance and space considerations are just as critical.
Some problems were here at the beginning and will still be here at the end.
