Signposts in Cyberspace


Book Description

The Domain Name System (DNS) enables user-friendly alphanumeric namesâ€"domain namesâ€"to be assigned to Internet sites. Many of these names have gained economic, social, and political value, leading to conflicts over their ownership, especially names containing trademarked terms. Congress, in P.L. 105-305, directed the Department of Commerce to request the NRC to perform a study of these issues. When the study was initiated, steps were already underway to address the resolution of domain name conflicts, but the continued rapid expansion of the use of the Internet had raised a number of additional policy and technical issues. Furthermore, it became clear that the introduction of search engines and other tools for Internet navigation was affecting the DNS. Consequently, the study was expanded to include policy and technical issues related to the DNS in the context of Internet navigation. This report presents the NRC's assessment of the current state and future prospects of the DNS and Internet navigation, and its conclusions and recommendations concerning key technical and policy issues.

Digital Foundations


Book Description

Fuses design fundamentals and software training into one cohesive book! The only book to teach Bauhaus design principles alongside basic digital tools of Adobe's Creative Suite, including the recently released Adobe CS4 Addresses the growing trend of compressing design fundamentals and design software into the same course in universities and design trade schools. Lessons are timed to be used in 50-minute class sessions. Digital Foundations uses formal exercises of the Bauhaus to teach the Adobe Creative Suite. All students of digital design and production—whether learning in a classroom or on their own—need to understand the basic principles of design in order to implement them using current software. Far too often design is left out of books that teach software. Consequently, the design software training exercise is often a lost opportunity for visual learning. Digital Foundations reinvigorates software training by integrating Bauhaus design exercises into tutorials fusing design fundamentals and core Adobe Creative Suite methodologies. The result is a cohesive learning experience. Design topics and principles include: Composition; Symmetry and Asymmetry; Gestalt; Appropriation; The Bauhaus Basic Course Approach; Color Theory; The Grid; Scale, Hierarchy and Collage; Tonal Range; Elements of Motion. Digital Foundations is an AIGA Design Press book, published under Peachpit's New Riders imprint in partnership with AIGA, the professional association for design.

Introduction to Electronic Chart Navigation: With an Annotated ECDIS Chart No. 1


Book Description

There are two types of electronic charts: raster navigational charts (RNC) and electronic navigational charts (ENC). RNC are exact copies of paper charts and their use underway comes naturally to navigators accustomed to paper charts. All traditional paper charts, however, and their RNC are being discontinued by NOAA. Many are gone already and all will be gone in a year or so. ENC (also called vector charts), on the other hand, include much more information than RNC; they allow user-selected display options that enhance safety and efficiency; and they are easier to keep up to date. But they do not look like traditional charts, and they do not behave like traditional charts. Navigation with ENC is fundamentally different from navigation with paper charts or RNC. Electronic charting benefits all mariners, professional and recreational, large vessels and small, power and sail, racing and cruising. The unique information in this book should help mariners in any of these categories master the use of ENC to enhance their safety and performance underway. There are many virtues of ENC, but to take advantage of these, a new approach to "reading charts" is called for. This book explains and illustrates the process. From the Forward to the Second Edition Two primary factors have taken place since the first edition that affect the content of this book. Foremost is the ongoing NOAA program to redesign the layout of all ENC to make them more consistent amongst themselves and with the ENC from other nations. This is a major improvement. The process is called rescheming. The most apparent changes are the shapes and coverages of the individual charts, which, when reschemed, become regular and consistent. Chart scales and depth contour conventions are also improved, plus we get a larger (more detailed) compilation scale for many areas. On top of these changes, the USCG has just completed a call for comments on the proposed new ruling that vessels must have some electronic chart viewer on board to effectively read the official ENC. In other words, we are at the moment when ENC have gone from an optional substitute for paper charts to being a required method of navigation. With all of this going on, we can see why NOAA decided it was time to take on the daunting task of rescheming all of the US ENC. We have added an appendix on rescheming to cover the details of the changes and how we recognize them in conjunction with what we now call the legacy ENC that exist before rescheming. The full conversion will take some years to complete, so we will be using the legacy ENC layouts for quite a while to come. The interpretation and basic use of ENC does not change with the reschemed charts. When a topic comes up in the book that is affected by rescheming, we make note of the changes with a reference to the appendix. There is also a short appendix on the new NOAA custom chart program (NCC); another on Inland ENC, the US Army Corps of Engineers charts for the Western Rivers; and one emphasizing a recommended vessel icon set up for navigation in strong wind or current. An overview of the next generation ENC called S-100 has also been added as an appendix. The second primary factor that has led to updates in this edition was the preparation for and first experiences we have had with our new training course on Electronic Chart Navigation. Many sections throughout the book have been enhanced to reflect the practical experience we gained. Interactions with students first learning a new subject is an invaluable resource we are lucky to have. Topics with more extensive updates include: coverage of the Quality of data object and Zone of Confidence attributes; treatment of magnetic variation; use of safety contour and safety depth; plus a new section on the use of encrypted S-63 charts with a specific example using the newly free ENC from New Zealand.
