    As the size and complexity of commercial software have grown, the gap between academic computer science and industry has widened. It's an open secret that there is little engineering in software engineering, which continues to rely not on codified scientific knowledge but on intuition and experience.Barr, who worked as a programmer for more than twenty years, describes how the industry has evolved, from the era of mainframes and Fortran to today's embrace of the cloud. He explains bugs and why software has so many of them, and why today's interconnected computers offer fertile ground for viruses and worms. The difference between good and bad software can be a single line of code, and Barr includes code to illustrate the consequences of seemingly inconsequential choices by programmers. Looking to the future, Barr writes that the best prospect for improving software engineering is the move to the cloud. When software is a service and not a product, companies will have more incentive to make it good rather than "good enough to ship."

    Despite it's name, unit testing is really a coding technique, not a testing technique. Unit testing is done by programmers, for programmers. It's primarily for our benefit: we get improved confidence in our code, better ability to make deadlines, less time spent in the debugger, and less time beating on the code to make it work correctly.This book shows how to write tests, but more importantly, it goes where other books fear to tread and gives you concrete advice and examples of what to test--the common things that go wrong in all of our programs. Discover the tricky hiding places where bugs breed, and how to catch them using the freely available JUnit framework. It's easy to learn how to think of all the things in your code that are likely to break. We'll show you how with helpful mnemonics, summarized in a handy tip sheet (also available from our pragmaticprogrammer.com website) to help you remember all this stuff.With this book you will:Write better code, and take less time to write it Discover the tricky places where bugs breed Learn how to think of all the things that could go wrong Test individual pieces of code without having to include the whole project Test effectively with the whole teamWe'll also cover how to use Mock Objects for testing, how to write high quality test code, and how to use unit testing to improve your design skills. We'll show you frequent "gotchas"--along with the fixes--to save you time when problems come up. We'll show you how with helpful mnemonics, summarized in a handy tip sheet (also available from our pragmaticprogrammer.com website).But the best part is that you don't need a sweeping mandate to change your whole team or your whole company. You don't need to adopt Extreme Programming or Test-Driven Development, or change your development process in order to reap the proven benefits of unit testing. You can start unit testing, the pragmatic way, right away.

    The 1980s were certainly loud, often garish and utterly fabulous - no matter how embarrassing the outfits were.There are so many elements, which made the 80s a truly great decade, but one of the greatest contributions, if not the greatest, is the mass introduction of affordable 8-bit home micro computers.These curious machines of geekdom changed the way we regarded computers and technology. No longer were they the sole perverse of tweed jacket clad scientists sporting unruly beards, micro computers were now forming a staple inventory in millions of homes.Much of the technology that we enjoy today, such as desktop computers, notebooks, tablets, gaming consoles and smart phones, all of which are often taken for granted, can be traced back to this innovative decade.If you were a child of the 80s and remember the joy of receiving your very first home computer or maybe a young adult who fondly remembers the excitement, then you will appreciate this unabashed reminiscence of a simpler time whose adolescent technological was on the cusp of great advancements.This book is intended as celebration and reflection of all the computer technology that made the 80s such a wonderful, pioneering period and follows the journey of a self confessed, teenaged computer geek who experienced and enjoyed every ground breaking moment, including publishing his own software.10 Print “The 80s are fab!”20 Goto 10RunAuthor's Comments:The current edition is dated 31st January 2016 and has been edited based on customer feedback.

    The rapid maturation of PHP has created a skeptical population of users from more traditional enterprise languages who question the readiness and ability of PHP to scale, as well as a large population of PHP developers without formal computer science backgrounds who have learned through the hands-on experimentation while developing small and midsize applications in PHP. While there are many books on learning PHP and developing small applications with it, there is a serious lack of information on scaling PHP for large-scale, business-critical systems. Schlossnagle's Advanced PHP Programming fills that void, demonstrating that PHP is ready for enterprise Web applications by showing the reader how to develop PHP-based applications for maximum performance, stability, and extensibility.

    Stories about weaknesses in cybersecurity like the "Heartbleed" leak, or malicious software on the cash registers at your local Target have become alarmingly common. Even more alarming is the sheer number of victims associated with these crimes--the identities and personal information of millions is stolen outright as criminals drain bank accounts and max out credit cards. The availability of stolen credit card information is now so common that it can be purchased on the black market for as little as four dollars with potentially thousands at stake for the victims. Possibly even more catastrophic are hackers at a national level that have begun stealing national security, or economic and trade secrets. The world economy and geopolitics hang in the balance.In Cyberphobia, Edward Lucas unpacks this shadowy, but metastasizing problem confronting our security--both for individuals and nations. The uncomfortable truth is that we do not take cybersecurity seriously enough. Strong regulations on automotive safety or guidelines for the airline industry are commonplace, but when it comes to the internet, it might as well be the Wild West. Standards of securing our computers and other internet-connected technology are diverse, but just like the rules of the road meant to protect both individual drivers and everyone else driving alongside them, weak cybersecurity on the computers and internet systems near us put everyone at risk. Lucas sounds a compelling and necessary alarm on behalf of cybersecurity and prescribes immediate and bold solutions to this grave threat.

    “The result is a veritable pi

    Along the way, we encounter black holes, turtles, snakes, dragons, axe-sharpening, and yak-shaving—and take a guided tour through the theories and methods, both brilliant and misguided, that litter the history of software development, from the famous ‘mythical man-month’ to Extreme Programming. Not just for technophiles but for anyone captivated by the drama of invention, Dreaming in Code offers a window into both the information age and the workings of the human mind.

    She brings it to its inadvertent creator, longtime programmer Ethan Levin, and the two embark on a hunt for the elusive bug, nicknamed “The Jester” for its tendency to appear randomly and only at the least opportune moments, jeopardizing the fate of the company. Ethan’s attempts to find a solution soon become a frightening obsession that threatens to destroy both his professional and personal life. Roberta, on the other hand, is drawn to the challenge. Forced to learn how to program, and seeking refuge from her own private troubles, she becomes enthralled with learning to speak the computer’s language. Expertly merging code with prose, big ideas with intensely personal stories, Ellen Ullman brilliantly illuminates the space between human beings and computers—a space we occupy every day as we peer into our monitors.

    Together, they ruled big business. They transformed popular culture. And they provoked a national controversy. More than anything, they lived a unique and rollicking American Dream, escaping the broken homes of their youth to produce the most notoriously successful game franchises in history—Doom and Quake— until the games they made tore them apart. This is a story of friendship and betrayal, commerce and artistry—a powerful and compassionate account of what it's like to be young, driven, and wildly creative.
