This guide illuminates the intricate relationship between data management, computer architecture, and system software. It traces the evolution of computing to today's data-centric focus and underscores the importance of hardware-software co-design in achieving efficient data processing systems with high throughput and low latency. The thorough coverage includes topics such as logical data formats, memory architecture, GPU programming, and the innovative use of ray tracing in computational tasks. Special emphasis is placed on minimizing data movement within memory hierarchies and optimizing data storage and retrieval. Tailored for professionals and students in computer science, this book combines theoretical foundations with practical applications, making it an indispensable resource for anyone wanting to master the synergies between data management and computing infrastructure.

Textbooks have long been considered a pivotal learning and teaching resource in classrooms. However, there is a paucity of research on how teachers use textbooks in relation to their beliefs, with analytic methods in such studies mainly restrained to content-based thematic analysis. To this end, from the perspectives of Halliday’s (1994) systemic functional linguistics (SFL) and Vygostky’s (1978) socio-cultural theory (SCT), this book explores how a Chinese college English teacher acts upon his beliefs and uses textbooks to mediate his students’ English learning in his classroom.Drawing on constructs of the SFL-based appraisal and speech function as well as interview excerpts, the study reveals that in the textbook-based classroom the Chinese college English teacher acts upon his beliefs that are constructed by diverse contextual factors. Implications of this study include using SFL and SCT to explore educators’ beliefs and practices and also providing effective teacher education for Chinese college English instructors to reshape their beliefs so that they are better prepared to use textbooks in classrooms.
