Personal Cybersecurity
by Marvin WaschkeDiscover the most prevalent cyber threats against individual users of all kinds of computing devices. This book teaches you the defensive best practices and state-of-the-art tools available to you to repel each kind of threat. Personal Cybersecurity addresses the needs of individual users at work and at home. This book covers personal cybersecurity for all modes of personal computing whether on consumer-acquired or company-issued devices: desktop PCs, laptops, mobile devices, smart TVs, WiFi and Bluetooth peripherals, and IoT objects embedded with network-connected sensors. In all these modes, the frequency, intensity, and sophistication of cyberattacks that put individual users at risk are increasing in step with accelerating mutation rates of malware and cybercriminal delivery systems. Traditional anti-virus software and personal firewalls no longer suffice to guarantee personal security. Users who neglect to learn and adopt the new ways of protecting themselves in their work and private environments put themselves, their associates, and their companies at risk of inconvenience, violation, reputational damage, data corruption, data theft, system degradation, system destruction, financial harm, and criminal disaster. This book shows what actions to take to limit the harm and recover from the damage. Instead of laying down a code of "thou shalt not" rules that admit of too many exceptions and contingencies to be of much practical use, cloud expert Marvin Waschke equips you with the battlefield intelligence, strategic understanding, survival training, and proven tools you need to intelligently assess the security threats in your environment and most effectively secure yourself from attacks. Through instructive examples and scenarios, the author shows you how to adapt and apply best practices to your own particular circumstances, how to automate and routinize your personal cybersecurity, how to recognize security breaches and act swiftly to seal them, and how to recover losses and restore functionality when attacks succeed. What You'll Learn Discover how computer security works and what it can protect us from See how a typical hacker attack works Evaluate computer security threats to the individual user and corporate systems Identify the critical vulnerabilities of a computer connected to the Internet Manage your computer to reduce vulnerabilities to yourself and your employer Discover how the adoption of newer forms of biometric authentication affects you Stop your router and other online devices from being co-opted into disruptive denial of service attacks Who This Book Is For Proficient and technically knowledgeable computer users who are anxious about cybercrime and want to understand the technology behind both attack and defense but do not want to go so far as to become security experts. Some of this audience will be purely home users, but many will be executives, technical managers, developers, and members of IT departments who need to adopt personal practices for their own safety and the protection of corporate systems. Many will want to impart good cybersecurity practices to their colleagues. IT departments tasked with indoctrinating their users with good safety practices may use the book as training material.

Person, Thing, Robot: A Moral and Legal Ontology for the 21st Century and Beyond
by David J. GunkelWhy robots defy our existing moral and legal categories and how to revolutionize the way we think about them.Robots are a curious sort of thing. On the one hand, they are technological artifacts—and thus, things. On the other hand, they seem to have social presence, because they talk and interact with us, and simulate the capabilities commonly associated with personhood. In Person, Thing, Robot, David J. Gunkel sets out to answer the vexing question: What exactly is a robot? Rather than try to fit robots into the existing categories by way of arguing for either their reification or personification, however, Gunkel argues for a revolutionary reformulation of the entire system, developing a new moral and legal ontology for the twenty-first century and beyond.In this book, Gunkel investigates how and why efforts to use existing categories to classify robots fail, argues that &“robot&” designates an irreducible anomaly in the existing ontology, and formulates an alternative that restructures the ontological order in both moral philosophy and law. Person, Thing, Robot not only addresses the issues that are relevant to students, teachers, and researchers working in the fields of moral philosophy, philosophy of technology, science and technology studies (STS), and AI/robot law and policy but it also speaks to controversies that are important to AI researchers, robotics engineers, and computer scientists concerned with the social consequences of their work.

Persistent Work-related Technology Use, Recovery and Well-being Processes
by Lenka Ďuranová Sandra OhlyTheaim of this work is to provide insight into the process of employee recoveryand well-being in regard to work-related ICT use during after-hours. Therefore,we discuss (1) theories that help us to understand the determinants andoutcomes of this behavior, (2) our core concepts recovery and well-being, and(3) previous empirical findings on ICT use after hours for work purposes. Onthe basis of literature review, we propose a new conceptual overall frameworkof ICT use after hours for work purposes with the focus on employee recoveryand well-being processes. Thereby, we posit ICT use after hours for workpurposes as potential stressor, resource, or demand (see action theory byHacker, 1998, 2003; Frese and Zapf 1994), depending on many personal and environmentalfactors, but primarily on cognitive appraisals (see transactional model ofstress by Lazarus and Folkman 1984). This three-way division enables us topropose various linear and non-linear associations to focused outcomes. Weconclude with an overall discussion on further research concerning theidentified research gaps.

Permanent Magnet Spherical Motors: Model And Field Based Approaches For Design, Sensing And Control (Research on Intelligent Manufacturing)
by Kun Bai Kok-Meng LeeThis book introduces and illustrates modeling, sensing, and control methods for analyzing, designing, and developing spherical motors. It systematically presents models for establishing the relationships among the magnetic fields, position/orientation and force/torque, while also providing time-efficient solutions to assist researchers and engineers in studying and developing these motors. In order to take full advantage of spherical motors’ compact structure in practical applications, sensing and control methods that utilize their magnetic fields and eliminate the need to install external sensors for feedback are proposed. Further, the book investigates for the first time spherical motors’ force/torque manipulation capability, and proposes algorithms enabling the ball-joint-like end-effector for haptic use based on these motors’ hybrid position/force actuation modes. While systematically presenting approaches to their design, sensing and control, the book also provides many examples illustrating the implementation issues readers may encounter.

Perl and XML: XML Processing with Perl
by Erik T. Ray Jason McIntoshXML is a text-based markup language that has taken the programming world by storm. More powerful than HTML yet less demanding than SGML, XML has proven itself to be flexible and resilient. XML is the perfect tool for formatting documents with even the smallest bit of complexity, from Web pages to legal contracts to books. However, XML has also proven itself to be indispensable for organizing and conveying other sorts of data as well, thus its central role in web services like SOAP and XML-RPC.As the Perl programming language was tailor-made for manipulating text, few people have disputed the fact that Perl and XML are perfectly suited for one another. The only question has been what's the best way to do it. That's where this book comes in.Perl & XML is aimed at Perl programmers who need to work with XML documents and data. The book covers all the major modules for XML processing in Perl, including XML::Simple, XML::Parser, XML::LibXML, XML::XPath, XML::Writer, XML::Pyx, XML::Parser::PerlSAX, XML::SAX, XML::SimpleObject, XML::TreeBuilder, XML::Grove, XML::DOM, XML::RSS, XML::Generator::DBI, and SOAP::Lite. But this book is more than just a listing of modules; it gives a complete, comprehensive tour of the landscape of Perl and XML, making sense of the myriad of modules, terminology, and techniques.This book covers:parsing XML documents and writing them out againworking with event streams and SAXtree processing and the Document Object Modeladvanced tree processing with XPath and XSLTMost valuably, the last two chapters of Perl & XML give complete examples of XML applications, pulling together all the tools at your disposal.

Perl Testing: A Developer's Notebook
by Ian Langworth ChromaticIs there any sexier topic in software development than software testing? That is, besides game programming, 3D graphics, audio, high-performance clustering, cool websites, et cetera? Okay, so software testing is low on the list. And that's unfortunate, because good software testing can increase your productivity, improve your designs, raise your quality, ease your maintenance burdens, and help to satisfy your customers, coworkers, and managers.Perl has a strong history of automated tests. A very early release of Perl 1.0 included a comprehensive test suite, and it's only improved from there. Learning how Perl's test tools work and how to put them together to solve all sorts of previously intractable problems can make you a better programmer in general. Besides, it's easy to use the Perl tools described to handle all sorts of testing problems that you may encounter, even in other languages.Like all titles in O'Reilly's Developer's Notebook series, this "all lab, no lecture" book skips the boring prose and focuses instead on a series of exercises that speak to you instead of at you. Perl Testing: A Developer's Notebook will help you dive right in and:Write basic Perl tests with ease and interpret the resultsApply special techniques and modules to improve your testsBundle test suites along with projectsTest databases and their dataTest websites and web projectsUse the "Test Anything Protocol" which tests projects written in languages other than PerlWith today's increased workloads and short development cycles, unit tests are more vital to building robust, high-quality software than ever before. Once mastered, these lessons will help you ensure low-level code correctness, reduce software development cycle time, and ease maintenance burdens. You don't have to be a die-hard free and open source software developer who lives, breathes, and dreams Perl to use this book. You just have to want to do your job a little bit better.

Perl Template Toolkit: Scalable Templating for the Web
by Darren Chamberlain Andy Wardley Dave CrossAmong the many different approaches to "templating" with Perl--such as Embperl, Mason, HTML::Template, and hundreds of other lesser known systems--the Template Toolkit is widely recognized as one of the most versatile. Like other templating systems, the Template Toolkit allows programmers to embed Perl code and custom macros into HTML documents in order to create customized documents on the fly. But unlike the others, the Template Toolkit is as facile at producing HTML as it is at producing XML, PDF, or any other output format. And because it has its own simple templating language, templates can be written and edited by people who don't know Perl. In short, the Template Toolkit combines the best features of its competitors, with ease-of-use and flexibility, resulting in a technology that's fast, powerful and extensible, and ideally suited to the production and maintenance of web content and other dynamic document systems.In Perl Template Toolkit you'll find detailed coverage of this increasingly popular technology. Written by core members of the technology's development team, the book guides you through the entire process of installing, configuring, using, and extending the Template Toolkit. It begins with a fast-paced but thorough tutorial on building web content with the Template Toolkit, and then walks you through generating and using data files, particularly with XML. It also provides detailed information on the Template Toolkit's modules, libraries, and tools in addition to a complete reference manual.Topics in the book include:Getting started with the template toolkitThe Template languageTemplate directivesFiltersPluginsExtending the Template ToolkitAccessing databasesXMLAdvanced static web page techniquesDynamic web content and web applicationsThe only book to cover this important tool, Perl Template Toolkit is essential reading for any Perl programmer who wants to create dynamic web content that is remarkably easy to maintain. This book is your surefire guide to implementing this fast, flexible, and powerful templating system.

Perl Graphics Programming: Creating SVG, SWF (Flash), JPEG and PNG files with Perl (O'reilly Ser.)
by Shawn WallaceGraphics programmers aren't the only ones who need to be proficient with graphics. Web and applications programmers know that a dull web page can be quickly transformed into one that's interesting and lively with the use of well-planned graphics. And fortunately, you don't need the skills of a fulltime graphics programmer to use graphics effectively. From access counters and log report graphs to scientific plots and on-the-fly animated GIFs, graphics scripting is within the grasp of most web programmers. Using open source software, like Perl, you have the power to dynamically generate graphics based on user input and activity, easily manipulate graphics content, and optimize graphics for compression and quality.Geared toward Perl users and webmasters, Perl Graphics Programming focuses on open-source scripting programs that manipulate graphics files for use on the Web. The book demystifies the manipulation of graphics formats for newcomers to the Web with a practical, resource-like approach. With this book you'll learn to:Generate dynamic web graphics with charts, tables, and buttonsAutomate graphics tasks (thumbnails and borders)Create dynamics web documents (PDF, Postscript)Produce rich Internet experiences with Flash and SVGYou'll begin with a tour of the most common web graphic file formats--PNG, JPEG, GIF, SWF, SVG, Postscript and PDF--then you'll explore the most powerful tools and Perl modules available for manipulating these graphics, such as GD, PerlMagick, and GIMP. Included in this part of the book is a thorough description of the Ming module for creating on-the-fly Flash files. Next, a "cookbook" section includes practical, all purpose recipes: GIF animation, generating images within a dynamic application, communicating between SWF front-end and Perl back-end, XSLT transformations, compression, and much more.Perl programmers naturally turn to Perl to tackle whatever challenge they have at hand, and graphics programming is no exception. Perl Graphics Programming provides all the tools you need to begin programming and designing graphics for the Web immediately. This book will change how you think about generating and manipulating graphics for the Web.
