Tile-based mapping systems have grown to become the dominant form of mapping system with the rise of Web-based mapping tools. The origin of this book is a desire to collect all our discoveries, techniques, and best practices for creating a til- mapping system into one combined volume. The intent of this text is to provide a comprehensive guide to the theory behind creating a tiled-map system as well as a practical guide to create a concrete implementation.

The Missing Tile and Other Stories is a collection of short stories and Saeed Ibrahim’s second book after the widely acclaimed family saga, Twin Tales from Kutcch. The fifteen stories in this collection are slice-of-life, character-based portraits reflecting on various aspects of human behaviour. Drawing us into the lives of ordinary people, their cares and concerns and their very human foibles and failings, these people-centric stories are sure to resonate with a large spectrum of readers, both young and old alike. Although the stories are set in India, the underlying themes are universal in their relevance. Some are light-hearted, tongue-in-cheek pieces on the quirks and idiosyncrasies in people’s behaviour, whilst others offer surprising insights into human nature’s compassionate and humane side. The tenor in the funny stories is entertaining and in the more serious ones connected with socially relevant issues; inspiring and thought-provoking. A notable feature is that the various stories in the collection celebrate India’s diversity, pluralism, and composite culture, which regrettably have been threatened in recent times. Danesh Bharucha’s imaginative sketches bring to life the characters in the stories and are skillfully adapted to suit the ambience and mood of these evocative tales.

The bachelor years are the single time in a man’s life when he is free to live the life of his choosing. Liberated of the shackles and expectations of his parents, he is yet unburdened by the future rigours and responsibilities that come with having a wife, kids, a career job, and endless bills that will routinely have him consider changing his name and fleeing to live out his days on a South American beach. A vast world of opportunity awaits the modern day bachelor. Whether it is the residence he chooses to support his lifestyle, the trials and tribulations he experiences in the world of dating and its accompanying nightlife, forays into social media and online dating, or even the occasional (and memorable) road trip or festival, each contributes to the life of a bachelor and is there to be enjoyed to the fullest. Experience the life of the bachelor. What it entails. The highs. The lows. Whether your approach is to prepare yourself for the bachelor years ahead, enhance the experience you are already enjoying, or use it to tap into the joys your life once held, no stone is left unturned. Join comedic author Travis J. Hawke and his A-Team/roundtable of girls for an entertaining look into the world of the modern day bachelor. Offering a unique perspective on the era a man only gets to experience once, ‘The Bachelor Life’ is a quintessential guide that can be used to maximise this fleeting time and showcase its true value.
