Introduction to Computing: Explorations in Language, Logic, and Machines

In the past hundred years, computer science has changed the world more than any other field. Without computer science, humans would not have walked on the Moon, modern medicine would not exist, and Wal-Mart would be a small store in Arkansas. But this book is not just about the pragmatic impact of computer science; it is about how computer science changes the way we think and how we solve problems.

This book is a survey introduction to the most important ideas in computing. It focuses on how to describe information processes by defining procedures, how to analyze the costs required to carry out a procedure, and the fundamental limits of what can and cannot be computed mechanically.

Computer science is the study of information processes. Computer scientists study how to describe, predict properties of, and efficiently implement information processes. When confronted with a problem, computer scientists do not just attempt to solve it. Instead, they think about a problem as a mapping between its inputs and desired outputs, develop a systematic sequence of steps for solving the problem for any possible input, and consider how the number of steps required to solve the problem scales as the input size increases. Thinking about problems this way has practical value since it leads to programs computers can execute to solve problems remarkably quickly, but also impacts the way we think about defining and solving problems regardless of whether or not a computer is involved.

Practical File System Design with the Be File System

This is the guide to the design and implementation of file systems in general, and the Be File System (BFS) in particular. This book covers all topics related to file systems, going into considerable depth where traditional operating systems books often stop. Advanced topics are covered in detail such as journaling, attributes, indexing and query processing. Built from scratch as a modern 64 bit, journaled file system, BFS is the primary file system for the Be Operating System (BeOS), which was designed for high performance multimedia applications.

You do not have to be a kernel architect or file system engineer to use Practical File System Design. Neither do you have to be a BeOS developer or user. Only basic knowledge of C is required. If you have ever wondered about how file systems work, how to implement one, or want to learn more about the Be File System, this book is all you will need.

Features:

    Review of other file systems, including Linux ext2, BSD FFS, Macintosh HFS, NTFS and SGI's XFS.
    Allocation policies for placing data on disks and discussion of on-disk data structures used by BFS
    How to implement journaling
    How a disk cache works, including cache interactions with the file system journal
    File system performance tuning and benchmarks comparing BFS, NTFS, XFS, and ext2
    A file system construction kit that allows the user to experiment and create their own file systems
