To read of sea roving's various incarnations - piracy, privateering, buccaneering, la flibuste, la course - is to bring forth romantic, and often violent, imagery. Indeed, much of this imagery has become a literary and cinematic clich?. And what an image it is! But its truth is by halves, and paradoxically it is the picaresque imagery of Pyle, Wyeth, Sabatini, and Hollywood that is often closer to the reality, while the historical details of arms, tactics, and language are often inaccurate or entirely anachronistic. Successful sea rovers were careful practitioners of a complex profession that sought wealth by stratagem and force of arms. Drawn from the European tradition, yet of various races and nationalities, they raided both ship and town throughout much of the world from roughly 1630 until 1730. Using a variety of innovative tactics and often armed with little more than musket and grenade, many of these self-described "soldiers and privateers" successfully assaulted fortifications, attacked shipping from small craft, crossed the mountains and jungles of Panama, and even circumnavigated the globe. Successful sea rovers were often supreme seamen, soldiers, and above all, tacticians. It can be argued that their influence on certain naval tactics is felt even today. The Sea Rover's Practice is the only book that describes in exceptional detail the tactics of sea rovers of the period - how they actually sought out and attacked vessels and towns. Accessible to both the general and the more scholarly reader, it will appeal not only to those with an interest in piracy and in maritime, naval, and military history, but also to mariners in general, tall-ship and ship-modeling enthusiasts, tacticians and military analysts, readers of historical fiction, writers, and the adventurer in all of us.

Many of the normal concerns faced by application developers are amplified by the challenges of web-scale concurrency, real-time performance expectations, multi-core support, and efficiently consuming services without constantly managing I/O blocks. Although it's possible to solve most of these issues with existing languages and frameworks, Go is designed to handle them right out of the box, making for a more natural and productive coding experience. Developed at Google for its own internal use, Go now powers dozens of nimble startups, along with name brands like Canonical, Heroku, SoundCloud, and Mozilla, who rely on highly performant services for their infrastructure. Go in Action introduces the unique features and concepts of the Go language, guiding readers from inquisitive developers to Go gurus. It provides hands-on experience with writing real-world applications including web sites and network servers, as well as techniques to manipulate and convert data at incredibly high speeds. It also goes in-depth with the language and explains the tricks and secrets that the Go masters are using to make their applications perform. For example, it looks at Go's powerful reflection libraries and uses real-world examples of integration with C code.
