The Boer War 1899-1902

The Boer War 1899-1902



Victorious in its previous campaigns in Africa against native armies, Britain now confronted an altogether different foe. The Boers proved to be formidable opponents, masterfully compensating for inferior numbers with grim determination, resourcefulness and strong religious faith. Their mobility, expert use of cover, and knowledge of the terrain, in which they employed powerful long-range magazine rifles, gave them initial advantages. By contrast the British suffered from inadequate transport, insufficient mounted troops and poor intelligence. Despite marshalling the immense resources of their empire, the British were to be severely tested in a war which one general described as ‘the graveyard of many a soldier’s reputation’.

Risk Analysis and Security Countermeasure Selection

Risk Analysis and Security Countermeasure Selection



When properly conducted, risk analysis enlightens, informs, and illuminates, helping management organize their thinking into properly prioritized, cost-effective action. Poor analysis, on the other hand, usually results in vague programs with no clear direction and no metrics for measurement. Although there is plenty of information on risk analysis, it is rare to find a book that explains this highly complex subject with such startling clarity. Very few, if any, focus on the art of critical thinking and how to best apply it to the task of risk analysis.

Mandarins of the Future

Mandarins of the Future



Because it provided the dominant framework for ‘development’ of poor, postcolonial countries, modernization theory ranks among the most important constructs of twentieth-century social science. In Mandarins of the Future: Modernization Theory in Cold War America Nils Gilman offers the first intellectual history of a movement that has had far-reaching and often unintended consequences.

AspectJ in Action

AspectJ in Action



A software system is the realization of a set of concerns. One of the central premises of object-oriented , is that each concern should be implemented as a separate module. However, there are certain system-wide concerns, such as logging, security, performance, and so forth, that often need to be addressed in many, if not all of the modules. Consequently, the code to handle these system-wide concerns may be mixed in with the core logic of a huge number of modules, resulting in lower productivity, poor quality, and systems that are hard to evolve.,

Aspect-oriented programming overcomes these problems by modularizing the system-wide concerns.
