The Spring issue of XRDS features contributions from the who’s who of cryptography. Within are a range of articles from the early beginnings of cryptography through present-day research. Discover modern cryptographic techniques like searchable encryption, read interviews with leading researchers in the field, and enjoy a wonderful look back at Bletchley Park, home of Colossus (the world’s first electronic digital computer)
More and more, technology is playing a crucial role in the reincarnation of healthcare. Today your personal health data is accessible at the touch of your fingertips. There is a growing market for mobile health apps and tracking (e.g. Apple Watch, FitBit, Jawbone etc.). With pervasive healthcare comes patient empowerment. Many of us are actively managing our own healthcare thanks to smart devices, online communities, and big data. From peer health groups to self tracking, in this issue we look at the cutting-edge research driving health informatics. Peer-oriented, collaborative allow patients to share their health information with one other; patient-contributed data is being used to discover novel medical insights; several technological efforts are helping to facilitate decision making, both on behalf of patients and on behalf of doctors; and work on interfaces and systems are helping people manage the day-to-day challenges of their medical conditions.
The current issue focuses on natural language processing (NLP), with an emphasis on humanistic applications that lie at the intersection of computer science and linguistics. The articles within this issue touch upon artificial intelligence and machine learning—specifically machine translation (e.g. “Google Translate”), speech recognition and synthesis, knowledge modeling using language, automatic summarization, automatic error detection and correction—as well as softer topics, such as work on the digitization of ancient Sumerian using modern computational tools and dialect switching in Arabic. (If you are so inclined, try to find the three “Easter eggs” hidden on the cover!)
When it comes to pursuing computer science, and science in general, at the doctorate level in the U.S., some groups are still lagging. Less than 6% of degree holders are Black and/or Hispanic, while 30% are women—although women make up 51% of the general population. In this issue, we tackled the following questions: Is there something inherently boring about CS to women? What are the barriers facing underrepresented minorities and women in the field? What aspects of CS in a social sense (constructs, culture) are unappealing to underrepresented groups? Why does diversity matter? Is CS—and more importantly, society—poorer for a lack of inclusivity? We hope the articles in this issue can further stimulate the conversation in and out of the classroom.
Computing in the new century is no longer confined to the desk, behind a monitor. It is wireless, ubiquitous, and on the go. It has taken to the skies, the oceans, and the land all around us. These cyber-physical systems are co-habitants of a complex and advanced ecology we have built for ourselves. Cyber-physical systems are electro-mechanical systems, which harness the power of computation, communication, control, and coordination to accomplish their assigned task(s) efficiently.
In this issue, we present the concept, applications, challenges, and progress of ubiquitous computing; the technologies that make computing infiltrate into every aspect of our daily lives; and the machines and systems that reshape the air, water, and land on earth.
"Wearable Computing" refers to embedding sensors and computation devices on the body in a seamless, unobtrusive, and invisible way. Such technology may very well revolutionize the way we live, behave, and interact. Beyond the current commercial applications, extensive research is being done to push the limits of wearable computing. Highlighted in this issue are applications in personal behavior monitoring, health care, and human-computer interaction. From monitoring a runner's performance in the field to using standard smartphone sensors as part of an mHealth project, there are endless opportunities to get dressed in tech.
When real and digital worlds collide things can get messy. Complicated problems surrounding privacy and anonymity arise as our interconnected world evolves technically, culturally, and politically. But what do we mean by privacy? By anonymity? Inside this issue we have contributions from lawyers, researchers, computer scientists, policy makers, and industry heavyweights all of whom try to answer the tough questions surrounding privacy, anonymity, and security. From cryptocurrencies to differential privacy, we look at how technology is used to protect our digital selves, and how that same technology can expose our vulnerabilities causing lasting, real-world effects.
This issue highlights how computers aid us all in realizing creative expression across various mediums. The presence of computers in our daily lives has produced an environment where various mediums coexist in a digital space where creativity can fly. Our images and data have quickly become creative artifacts. The emergence of online, collective communities, which support new forms of combined creativity, is leading to new types of creative partnerships. In many ways the tools that we use or produce for creative ends can enable or hinder artists. This all begs the question: Who owns this content? Video mashups, online music composition, animation, visual effects, computational origami are just some of the ideas explored in this issue.
Solving large-scale, complex problems, such as climate change or nuclear stockpile stewardship, would be next to impossible without scientific computing. And thanks to advances in high-performance computing, scientific computing continues to flourish. Scientific computing, also known as computational science, emphasizes interdisciplinary collaboration in the development of computer programs, software applications, and computer simulations. The intersection of computer science, engineering, and applied mathematics is at the heart of scientific computing; computer-based models are used to analyze diverse scientific problems across biology, geology, chemistry, ecology, climatology, and physics, to name a few. For those of you who are computational scientists, or leaning in that direction, this issue provides a comprehensive overview of a diverse and growing field.
The power of technology could improve the lives of millions of people around the world. ICTD (Information and Communication Technologies and Development) addresses some of the most critical societal issues across the globe, including healthcare, education, crime, finance, and agriculture. However the challenge for computer scientists is to not only produce feasible solutions but to do so in the context of the developing world. Not only must technical constraints be accounted for, but also there are foundational issues inherent to the target community that have to be addressed. This issue of XRDS focuses on the unique challenges and opportunities within ICTD.
Big data is everywhere—from financial transactions to Tweets, from ad click throughs to medical records—and is continuously growing. The Information Age has lead to a proliferation of data across all industries. However harnessing all of this data can be a daunting task. There are many challenges facing the big data community. In this issue we provide a comprehensive overview of recent developments affecting big data. The issue is divided into three main themes: theory, systems, and applications. We've also included discussions on how data is used in the real word at IBM and Google. As more businesses use data analytics to make better strategic decisions, there is an increasing need for educated researchers, scientists, and engineers. We hope to encourage our readers to explore this growing field.
In today's world of mobile apps and social media, an entrepreneurial sprit is no longer just for the adventurous. It's safe to assume that anyone with basic programming skills has considered jumping into the deep end to find success in the startup world. And it's not so surprising, considering the everyday tools we use began as startups: Google, Facebook, Twitter, Groupon, Instagram. From dedicated conferences like TechCrunch Disrupt to venture capitalist bloggers, startups are big business. We've compiled interviews and articles from those with direct experience working for, funding, and launching a startup. We hope this issue will fill in the gaps you may have about starting your own business. Perhaps upon turning that last page you realize a startup is not for you, or you may be reinvigorated to go out there and make your mark. In light of Facebook's recent IPO struggles, it's apparent that you will need more than a big idea. If you're willing to take the risk, you may be part of something that fundamentally changes how we live.
2012 has been designated the "Alan Turning Year." Celebrations on both sides of the pond are being held to commemorate Alan Turing's legacy. His contributions to not only computer science, but society as well, are vast. In this special issue of XRDS, we explore what we mean by computation; consider the relevancy of Turing's work today; discuss computational complexity, while taking a detour into cryptography; and wrap up with what the future holds for computing. If Turing is the "Father of Computer Science,” we as his descendants must continue to push the boundaries of computing science.
Since the passing of the Freedom of Information of Act in 1966, open government has become a term bandied about by journalists, activists, and even the current President of the United States. However more than the declassification of state secrets, information access—spurred on by the World Wide Web—has opened the door for a global movement: open democracy. The combined efforts of politicians, programmers and everyday citizens are highlighted in the latest issue of XRDS. From censorship to crimemapping, we explore how computer science can strengthen democracy.
Your brain is a wonderful and powerful thing—it is intricately involved with everything you do and everything that makes you who you are. As the interests of computer scientists gravitate toward the brain, entirely new questions emerge. Can we monitor the brain while writing a paper, playing a game, or performing a musical piece? Can we study how the brain learns and use it to influence and improve our own algorithms? Can we create computer applications that are attentive to our situational cognitive needs?
Although technology has improved our lives in immeasurable ways, it does have a cost. As computer scientists, engineers, designers, we often forget about the impact of our work. In this issue of XRDS, we explore the relationship between technology and environmental sustainability. Presented here are tangible ways technology is being used to inform better decisions, reduce energy consumption, and address the tradeoffs between globalization and a fragile ecosystem.
It’s been one year since we redesigned and renamed the magazine.
