Brian Kernighan on what we all need to know about computers

KernighanLaptops, tablets, cell phones, and smart watches: computers are inescapable. But even more are invisible, like those in appliances, cars, medical equipment, transportation systems, power grids, and weapons. We never see the myriad computers that quietly collect, share, and sometimes leak vast amounts of personal data about us, and often don’t consider the extent to which governments and companies increasingly monitor what we do. In Understanding the Digital World, Brian W. Kernighan explains, in clear terms, not only how computers and programming work, but also how computers influence our daily lives. Recently, Kernighan answered some questions about his new book.

Who is this book for? What kind of people are most likely to be interested?

BK: It’s a cliché, but it really is aimed at the proverbial “educated layman.” Everyone uses computers and phones for managing their lives and communicating with other people. So the book is for them. I do think that people who have some technical background will enjoy it, but will also find that it will help their less technical friends and family understand.

What’s the basic message of the book?

BK: Computers—laptops, desktops, tablets, phones, gadgets—are all around us. The Internet lets our computers communicate with us and with other computers all over the world. And there are billions of computers in infrastructure that we rely on without even realizing its existence. Computers and communications systems have changed our lives dramatically in the past couple of decades, and will continue to do so. So anyone who hopes to be at least somewhat informed ought to understand the basics of how such things work. One major concern has been the enormous increase in surveillance and a corresponding reduction in our personal privacy. We are under continuous monitoring by government agencies like the NSA in the United States and similar ones in other countries. At the same time, commercial interests track everything we do online and with our phones. Some of this is acceptable, but in my opinion, it’s gone way too far. It’s vital that we understand better what is being done and how to reduce the tracking and spying. The more we understand about how these systems work, the more we can defend ourselves, while still taking advantage of the many benefits they provide. For example, it’s quite possible to explore interesting and useful web sites without being continuously tracked. You don’t have to reveal everything about yourself to social networks. But you have to know something about how to set up some defenses. More generally, I’m trying to help the reader to reach a better than superficial understanding of how computers work, what software is and how it’s created, and how the Internet and the Web operate. Going just a little deeper into these is totally within the grasp of anyone. The more you know, the better off you will be; knowing even a little about these topics will put you ahead of the large majority of people, and will protect you from any number of foolish behaviors.

Can you give us an example of how to defend ourselves against tracking by web sites?

BK: Whenever you visit a web site, a record is made of your visit, often by dozens of systems that are collecting information that can be used for targeted advertising. It’s easy to reduce this kind of tracking by turning off third-party cookies and by installing some ad-blocking software. You can still use the primary site, but you don’t give away much if anything to the trackers, so the spread of information about you is more limited.

If I don’t care if companies know what sites I visit, why should I be worried?

BK: “I’ve got nothing to hide,” spoken by an individual, or “If you have nothing to hide, you have nothing to fear,” offered by a government, are pernicious ideas. They frame the discussion in such a way as to concede the point at the beginning. Of course you have nothing to hide. If that’s true, would you mind showing me your tax returns? How did you vote in the last election? What’s your salary? Could I have your social security number? Could you tell me who you’ve called in the past year? Of course not—most of your life is no one else’s business.

What’s the one thing that you would advise everyone to do right now to improve their online privacy and security?

BK: Just one thing? Learn more about how your computer and your phone work, how the Internet works, and how to use all of them wisely. But I would add some specific recommendations, all of which are easy and worthwhile. First, in your browser, install defensive extensions like like AdBlock and Ghostery, and turn off third-party cookies. This will take you less than ten minutes and will cut your exposure by at least a factor of ten. Second, make sure that your computer is backed up all the time; this protects you against hardware failure and your own mistakes (both of which are not uncommon), and also against ransomware (though that is much less a risk if you are alert and have turned on your defenses). Third, use different passwords for different sites; that way, if one account is compromised, others will not be. And don’t use your Facebook or Google account to log in to other sites; that increases your vulnerability and gives away information about you for minor convenience. Finally, be very wary about clicking on links in email that have even the faintest hint of something wrong. Phishing attacks are one of the most common ways that accounts are compromised and identities stolen.

From “Brexit” to “dumpster fire”: Benjamin Peters on why digital keywords matter

petersIn the digital age, words are increasingly important, with some taking on entirely different meanings in the digital world. Benjamin Peters’ new book, Digital Keywords: A Vocabulary of Information Society & Culture  presents modern humans as linguistic creatures whose cultural, economic, political, and social relations are inseparable from these “keywords”. Recently, Peters took the time to answer some questions about the book:

Why digital keywords? Why now?

BP: “Brexit” and “Trumpmemtum.”

What are these but marked keywords that—together with, say, the trendy new phrase “dumpster fire”—trigger anxieties very much alive today? What work do such words do?

40 years ago, in 1976, the Welsh literary critic Raymond Williams published his classic Keywords: A Vocabulary of Culture and Society, establishing a critical and ongoing project for taking seriously the work of over 100 words in postindustrial Britain. This book, taking Williams as its (all too) timely inspiration, seeks to refresh the keywords project for English-language information societies and cultures worldwide.

This book seeks to change the conversation about the digital revolution of language at hand. The real world may not be made out of language but our access to it surely is. Modern humans are linguistic creatures: our cultural, economic, political, social, and other relations cannot be separated from the work our words do. And as everyone who has ever put pencil to paper knows, our words do not always oblige. This is especially true in the age of search. Digital keywords are both indispensable and tricky. They are ferociously important and often bite back.

Digital Keywords also seeks to offer a teachably different approach to “digital keywords” than currently championed, as a simple Google search will reveal, by the meddling reach of search engine optimizers (SEO). No older than the OJ Simpson trial and valued at no less than $65 billion (about the economy of Nebraska), the SEO industry is arguably the dominant approach to taking keywords seriously online at the moment: and yet reason strains at the massive capital flows that, say, the term “insurance” alone commands. SEO, with its shady markets of pay-per-click advertising and results manipulation, cannot be the best approach to working with digital keywords.

How else might we begin (again)?

I’m hooked. So which keywords does the book take up? And what makes those words key?

BP: Let me answer that in reverse. As editor I figured I had a choice: I could either start by choosing the words I thought were key for the information age and then find people to write about them, or I could invite the best contributors to the project and then let them choose their keywords. As it happens, this volume does both. On the one hand, the appendix lists well over 200 candidate keywords—from access to zoom—and we’ll be soliciting other keywords to that growing list on the scholarly blog Culture Digitally this July.

On the other hand, the 25 words featured in this book are “key” simply because the scholars that populate this book demonstrate that they are. That may sound tautological, but I actually uphold it as the high standard in keyword scholarship: a word is key because it does meaningful social work in our lives. It is the task of each essay to prove such work. The reader too is invited to take up Williams’ search for themselves and to test these essays accordingly: do they convince that these terms, once understood, are somehow tectonic to the modern information society and culture—and why or why not? Which words would you add—and why?

Fair enough. Can you give us a sample of what the authors claim about their keywords?

BP: Sure thing. The freely available extended introduction critically frames the project as a first step toward a grammar for understanding terministic technologies; it also summarizes each essay and draws critical connections between them, so I won’t do any of that here. Since the book itself is organized alphabetically by keyword, I’ll list the essays alphabetically by author last name. Rosemary Avance critically reclaims community online and off, Saugata Bhaduri risks the collective action baked into gaming, Sandra Braman tackles Williams’ keyword flow in information systems, Gabriella Coleman decrypts hackers and their crafts, Jeffrey Drouin takes on document surrogates in copy cultures, Christina Dunbar-Hester critically appraises the gender in computing geeks, Adam Fish reflects on what mirror is doing in data mirroring, Hope Forsyth grounds the online forum in ancient Rome, Bernard Geoghegan telegraphs back the origins of modern information, Tarleton Gillespie demystifies the omnipresent algorithm, Katherine D. Harris unpacks the digital archive, Nicholas A. John rethinks sharing cultures online, Christopher Kelty unearths root causes and consequences of participation, Rasmus Kleis Nielsen separates democracy from digital technologies, John Durham Peters seeds an outpouring of the cloud in cloud computing, Steven Schrag reworks memory and its mental and mechanical discontents, Stephanie Ricker Schulte repossesses personalization, Limor Shifman reanimates the meme online, Julia Sonnevend theorizes events beyond media, Jonathan Sterne and I, separately, deconstruct the analog and digital binary, Thomas Streeter pluralizes the internet, Ted Striphas rereads culture alongside technology after Williams, Fred Turner goes Puritan on the Silicon Valley prototype, and Guobin Yang launches the book with the de-radicalizing of activism online.

Who is the audience for this book? Who are you writing for?

BP: Students, scholars, and general interest readers interested in the weighty role of language in the age of search in particular and the current information age in general. Ideally, each essay will prove plain and short enough (average length 3000 words) to sustain the attention of the distracted undergraduate, substantial enough to enrich the graduate students, and pointed enough to provoke constructive criticism from the most experienced scholar. Of course this ideal will not hold uniformly across this or any other volume, but perhaps this group of contributors delivers on the whole, I must say, and that is enough for this editor.

I’m also excited to note that later this year Princeton University Press also plans to release for free download my teaching notes for this book. These notes aim to offer in an easily editable format enough material to teach the book as the main course text for a semester-long undergraduate or graduate course in media and communication studies. We hope this will benefit courses worldwide. Meanwhile, the scholarly blog Culture Digitally maintains, with Princeton University Press’ generous support, the early drafts of fair share of the published essays here.

Benjamin Peters is assistant professor of communication at the University of Tulsa in Tulsa, Oklahoma. He is also affiliated faculty at the Information Society Project at Yale Law School.
