This is a new approach to learning old English - as a living language. Leofwin and his family are your guides through six lively, entertaining, topic-based units. New vocabulary and grammar are presented in context, step by step, so that younger readers and non-language specialists can feel engaged rather than intimidated. The author has complemented the text with a wealth of illustrations throughout. This volume is the first part of the course.

Zur System- oder Gerätetreiber-Programmierung unter Linux benötigen Sie einen Leitfaden, der den Aufbau des Linux-Kernels und das Zusammenwirken seiner Subsysteme und Schnittstellen in der nötigen Tiefe verständlich erklärt. Das „Linux-Kernel-Handbuch“ ist dieser Leitfaden. Der Autor – selbst langjähriger Kernel-Hacker – erschließt seinen Lesern die dunklen Tiefen des Allerheiligsten mit leicht verständlichen Erklärungen auch schwieriger und komplexer Sachverhalte.
