Thinking in Systems: A Primer html

Pdf background Amazon button
Book Review

In the years following her role as the lead author of the international bestseller, Limits to Growth―the first book to show the consequences of unchecked growth on a finite planet― Donella Meadows remained a pioneer of environmental and social analysis until her untimely death in 2001.

Thinking in Systems, is a concise and crucial book offering insight for problem solving on scales ranging from the personal to the global. Edited by the Sustainability Institute’s Diana Wright, this essential primer brings systems thinking out of the realm of computers and equations and into the tangible world, showing readers how to develop the systems-thinking skills that thought leaders across the globe consider critical for 21st-century life.

Some of the biggest problems facing the world―war, hunger, poverty, and environmental degradation―are essentially system failures. They cannot be solved by fixing one piece in isolation from the others, because even seemingly minor details have enormous power to undermine the best efforts of too-narrow thinking.

While readers will learn the conceptual tools and methods of systems thinking, the heart of the b...

The Red Web: The Struggle Between Russia's Digital Dictators and the New Online Revolutionaries cover
Book Review

Half of Russia’s email traffic passes through an ordinary-looking building in an otherwise residential district of South West Moscow. On the eighth floor, in here a room occupied by the FSB, the successor organization to the KGB, is a box the size of a VHS player, marked SORM. SORM once intercepted just phone calls. Now it monitors emails, internet usage, Skype, and all social networks. It is the world’s most intrusive listening device, and it is the Russian Government’s front line for the battle of the future of the internet.

Drawn from scores of interviews personally conducted with numerous prominent officials in in the ministry of communications and web-savvy activists challenging the state, Andrei Soldatov and Irina Borogan’s fearless investigative reporting in The Red Web is both harrowing and alarming. They explain the long and storied history of Russian advanced surveillance systems, from research laboratories in Soviet era labor camps to the legalization of government monitoring of all telephone and internet communications in 1995.

But for every hacker subcontracted by the FSB to interfere with Russia’s antagonists abroad—such as t...
