After the defeat at Colenso, the Natal Field Force under General Buller needed to break through the Boer lines and relieve the besieged town of Ladysmith. Buller’s army marched westwards, crossed the Tugela River at Trichardt’s Drift and Potgieter’s Drift, and from 17-27 January 1900 fought the Boers with artillery and infantry attacks. These significant and prolonged battles have largely been ignored because of the horror of Spion Kop (Spioenkop) on 24 January. Yet Spion Kop began as a small flank attack - only a tenth of the British force were initially involved, and only 300 Boers counter-attacked.

This book is the culmination of years of study, and correctly places Spioenkop in the context of the larger campaign. The author uses battlefield archaeology and eyewitness accounts of Boer and British participants to create a highly original and detailed account. This book also serves as a battlefield guide to Tabanyama and Spioenkop, providing detailed maps and numerous GPS locations.

With Bluetooth Low Energy (BLE), smart devices are about to become even smarter. This practical guide demonstrates how this exciting wireless technology helps developers build mobile apps that share data with external hardware, and how hardware engineers can gain easy and reliable access to mobile operating systems.

This book provides a solid, high-level overview of how devices use BLE to communicate with each other. You’ll learn useful low-cost tools for developing and testing BLE-enabled mobile apps and embedded firmware and get examples using various development platforms—including iOS and Android for app developers and embedded platforms for product designers and hardware engineers.

- Understand how data is organized and transferred by BLE devices
- Explore BLE’s concepts, key limitations, and network topology
- Dig into the protocol stack to grasp how and why BLE operates
- Learn how BLE devices discover each other and establish secure connections
- Set up the tools and infrastructure for BLE application development
- Get examples for connecting BLE to iPhones, iPads, Android devices, and sensors
- Develop code for a simple device that transmits heart rate data to a mobile device

An uneasy truce between IRA assassin Declan Rath and ex SAS soldier 'Spider' Webb adds to the spiralling tension as a Tuzla-bound convoy battles through war-torn Bosnia to bring aid to the beleaguered city. Targeted for destruction by Croatian Military Intelligence and Serbian para-militaries, the convoy, unwitting carrier of smuggled arms, is prey to all sides.

Ulli Steltzer, a distinguished photographer, takes the reader into the carving shed and studio to see Robert Davidson as he creates both monumental poles and intricately detailed powerful masks. More than 100 of her black-and-white photographs, reproduced in duotone, record both the evolution of Davidson and his art, from the early days up to the present, a span of 25 years. In the accompanying text and captions, Robert Davidson writes movingly about growing up Haida and his development as an artist, describes the creative and practical process of carving poles and masks, and discusses the place of art in Haida culture.
