From the former news policy lead at Google, an urgent and groundbreaking account of the high-stakes global cyberwar brewing between Western democracies and the autocracies of China and Russia that could potentially crush democracy. From 2016 to 2020, Jacob Helberg led Google's global internal product policy efforts to combat disinformation and foreign interference. During this time, he found himself in the midst of what can only be described as a quickly escalating two-front technology cold war between democracy and autocracy. On the front-end, we're fighting to control the software--applications, news information, social media platforms, and more--of what we see on the screens of our computers, tablets, and phones, a clash which started out primarily with Russia but now increasingly includes China and Iran. Even more ominously, we're also engaged in a hidden back-end battle--largely with China--to control the Internet's hardware, which includes devices like cellular phones, satellites, fiber-optic cables, and 5G networks. This tech-fueled war will shape the world's balance of power for the coming century as autocracies exploit twenty-first-century methods to re-divide the world into twentieth century-style spheres of influence. Helberg cautions that the spoils of this fight are power over every meaningful aspect of our lives, including our economy, our infrastructure, our national security, and ultimately, our national sovereignty. Without a firm partnership with the government, Silicon Valley is unable to protect democracy from the autocrats looking to sabotage it from Beijing to Moscow and Tehran. The stakes of the ongoing cyberwar are no less than our nation's capacity to chart its own future, the freedom of our democratic allies, and even the ability of each of us to control our own fates, Helberg says. And time is quickly running out.

Numerical linear algebra, digital signal processing, and parallel algorithms are three disciplines with a great deal of activity in the last few years. The interaction between them has been growing to a level that merits an Advanced Study Institute dedicated to the three areas together. This volume gives an account of the main results in this interdisciplinary field. The following topics emerged as major themes of the - Singular value and eigenvalue decompositions, including applications, - Toeplitz matrices, including special algorithms and architectures, - Recursive least squares in linear algebra, digital signal processing and control, - Updating and downdating techniques in linear algebra and signal processing, - Stability and sensitivity analysis of special recursive least squares problems, - Special architectures for linear algebra and signal processing. This book contains tutorials on these topics given by leading scientists in each of the three areas. A consider- able number of new research results are presented in contributed papers. The tutorials and papers will be of value to anyone interested in the three disciplines.
