    Often, a photographer will spend long days capturing photos only to return with a set of images that he or she is not completely satisfied with. Sure, the lighting and exposure may have turned out great, but the overall composition of the photos leaves something to be desired. In short, they lack that “wow” factor that they see in other photographers’ shots.Composition is the foundation in which great photography is built upon. A photo may be properly lit and contain good subject matter, but if it is doesn’t have good composition it will never be considered more than an amateur shot. How can you overcome this? We’ll teach you in this book. Finally, a Book on the Art of Photography that Teaches Tips and Tricks for Creative Composition!

    Leading networking authority Douglas Comer presents a wide-ranging, self-contained tour of the concepts, principles, and technologies that enable today's Internet to support applications ranging from web browsing to telephony and multimedia. This Fifth Edition has been thoroughly reorganized, revised, and updated: it includes extensive new coverage of topics ranging from wireless protocols to network performance, while reducing or eliminating coverage of older protocols and technologies. Comer begins by illuminating the applications and facilities offered by today's Internet. Next, he systematically introduces the underlying network technologies and protocols that make them possible: low-level data communications; packet switching, LAN, and WAN technologies; and Internet protocols such as TCP, IP, UDP, and IPv6. With these concepts and technologies established, he introduces several of the most important contemporary issues faced by network implementers and managers, including quality of service, Internet telephony, multimedia, network security, and network management. Comer has carefully designed this book to support both top-down and bottom-up teaching approaches. Students need no background in operating systems, and no sophisticated math: Comer relies throughout on figures, drawings, examples, and analogies, "not" mathematical proofs.

    

    Yet as a complete beginner, and a terrified one at that, in April 2018 Fiona set out to see if she could stand up paddleboard up the west coast of Britain, 800 miles from Land’s End to John O’Groats (LEJOG). Having walked and cycled LEJOG the year before, something inexplicably compelled her to see if she could turn her previous adventures into a length of Britain triathlon and set three new world records. Along the way Fiona was joined by dolphins, paddled 40 miles across the Irish Sea, and battled past whirlpools. This inspiring and gripping account shows that no matter what the odds, if you dare to start before you’re ready, anything is possible. "Fiona’s stand up paddleboard adventure certainly tested her to the limits. Having had a bad experience in water when she was a child, and then to put herself in a situation that pushes on that fear, week after week, is no mean feat. Along the way she lost sight of shore to paddle across the Irish Sea, becoming the first woman to do so. Through all of the challenges she faced, it was her belief in herself and those around her that enabled her to keep moving forwards." - Sean Conway Fiona Quinn is a keynote speaker, endurance adventurer and entrepreneur. Sharing stories with everyone from school children to business executives, she enthusiastically invites you to change your view of what’s possible.

    Jon has done a wonderful job of updating the material. I am very impressed at how fresh the new examples seem." - Steve McConnell, author, Code CompleteWhen 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 (1) testing, debugging, and timing; (2) set representations; and (3) 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, this book is sure to make your own list of favorites.
