This book predicts the decline of todays professions and describes the people and systems that will replace them. In an Internet society, according to Richard Susskind and Daniel Susskind, we will neither need nor want doctors, teachers, accountants, architects, the clergy, consultants, lawyers, and many others, to work as they did in the 20th century. The Future of the Professions explains how increasingly capable systems - from telepresence to artificial intelligence - will bring fundamental change in the way that the practical expertise of specialists is made available in society. The authors challenge the grand bargain - the arrangement that grants various monopolies to todays professionals. They argue that our current professions are antiquated, opaque and no longer affordable, and that the expertise of the best is enjoyed only by a few. In their place, they propose six new models for producing and distributing expertise in society. The book raises important practical and moral questions. In an era when machines can out-perform human beings at most tasks, what are the prospects for employment, who should own and control online expertise, and what tasks should be reserved exclusively for people? Based on the authors in-depth research of more than ten professions, and illustrated by numerous examples from each, this is the first book to assess and question the relevance of the professions in the 21st century.

Linux From Scratch describes the process of creating your own Linux system from scratch from an already installed Linux distribution, using nothing but the source code of software that you need. From the author's introduction: "Having used a number of different Linux distributions, I was never fully satisfied with either of those. I didn't like the way the bootscripts were arranged, or I didn't like the way certain programs were configured by default and more of those things. I came to realize that when I want to be totally satisfied with a Linux system, I have to build my own Linux system from scratch. Ideally only using the source code. No pre-compiled packages of any kind. No help from some sort of cdrom or bootdisk that would install some basic utilities. You would use your current Linux system and use that one to build your own. This, at one time, wild idea seemed very difficult and at times almost impossible. The reason for most problems were due to my lack of knowledge about certain programs and procedures. After I sorted out all kinds of dependency problems, compilation problems, etcetera, a manually Linux system was created and fully operational. I called this system and LFS system which stands for Linux From Scratch."

There is a contradiction at the heart of digital media. We use commercial platforms to express our identity, to build community and to engage politically. At the same time, our status updates, tweets, videos, photographs and music files are free content for these sites. We are also generating an almost endless supply of user data that can be mined, re-purposed and sold to advertisers. As users of the commercial web, we are socially and creatively engaged, but also labourers, exploited by the companies that provide our communication platforms. How do we reconcile these contradictions? Feminism, Labour and Digital Media argues for using the work of Marxist feminist theorists about the role of domestic work in capitalism to explore these competing dynamics of consumer labour. It uses the concept of the Digital Housewife to outline the relationship between the work we do online and the unpaid sphere of social reproduction. It demonstrates how feminist perspectives expand our critique of consumer labour in digital media. In doing so, the Digital Housewife returns feminist inquiry from the margins and places it at the heart of critical digital media analysis.
