He was one of the pioneers of publishing on desktop computers, starting with the very fi rst digital design and graphics programs, PageMaker and Photoshop. Like so many of the early “desktop publishers,” with the emergence of the World Wide Web, he found that making the transition to web design was the next logical step. His design fi rm has designed hundreds of websites, Flash websites, and electronic documents. His earlier books on Photoshop, PageMaker, and digital media in general were some of the fi rst publications on these topics. William Harrel has authored or coauthored 19 books on designing both print media and electronic documents, such as websites, PDFs, Flash sites and Flash applications, slide and multimedia presentations, on computers. These include titles on Photoshop, Acrobat (Acrobat For Dummies), PageMaker, Flash, Director, and several other graphics and publishing packages. His latest online courses, Introduction to Adobe Flash CS4, Introduction to Adobe Flash CS5, Intermediate Adobe Flash CS4, and Intermediate Adobe Flash CS5, are currently offered at more than 2,500 colleges and universities. These are fully accredited courses offering in-depth instruction on Flash, including lessons on developing Flash applications for handheld devices. He has also written hundreds of magazine articles, ranging in subject matter from Mac, PC, and other hardware reviews to all types of software packages — including page layout, graphics, web design, Flash, multimedia, and word processing — in such notable magazines as PC World, Home Offi ce Computing, Compute, Windows Magazine, Publish, Entrepreneur, Home Offi ce, and many, many others. He currently reviews printers, notebook computers, and tablets for Computer Shopper. Harrel’s blog, Communications Technology Watch (http://comm techwatch.com), is a well-respected source for information related to media designed for and on computers. Communications Technology Watch contains volumes of material on using Flash and other applications, includ- ing most programs in the Adobe Creative Suite. William Harrel was also the owner-operator of a nationwide Internet Service Provider (ISP) for 14 years.

  • Browser Versions Carry 10.5 Bits of Identifying Information on Average [Forthcoming Blog Post]
    Browser versions carry 10.5 bits of identifying information on average [forthcoming blog post] Technical Analysis by Peter Eckersley This is part 3 of a series of posts on user tracking on the modern web. You can also read part 1 and part 2. Whenever you visit a web page, your browser sends a "User Agent" header to the website saying what precise operating system and browser you are using. We recently ran an experiment to see to what extent this information could be used to track people (for instance, if someone deletes their browser cookies, would the User Agent, alone or in combination with some other detail, be enough to re-create their old cookie?). Our experiment to date has shown that the browser User Agent string usually carries 5-15 bits of identifying information (about 10.5 bits on average). That means that on average, only one person in about 1,500 (210.5) will have the same User Agent as you. On its own, that isn't enough to recreate cookies and track people perfectly, but in combination with another detail like an IP address, geolocation to a particular ZIP code, or having an uncommon browser plugin installed, the User Agent string becomes a real privacy problem. User Agents: An Example of Browser Characteristics Doubling As Tracking Tools When we analyse the privacy of web users, we usually focus on user accounts, cookies, and IP addresses, because those are the usual means by which a request to a web server can be associated with other requests and/or linked back to an individual human being, computer, or local network.

Browsing behavior has been traditionally represented and studied by means of clickstreams, i.e., graphs whose vertices are web pages, and edges are the paths followed by users. Obtaining large and representative data to extract clickstreams is however challenging. The evolution of the web questions whether browsing behavior is changing and, by consequence, whether properties of clickstreams are changing. This paper presents a longitudinal study of clickstreams in from 2013 to 2016. We evaluate an anonymized dataset of HTTP traces captured in a large ISP, where thousands of households are connected. We rst propose a methodology to identify actual URLs requested by users from the massive set of requests automatically red by browsers when rendering web pages. Then, we characterize web usage patterns and clickstreams, taking into account both the temporal evolution and the impact of the device used to explore the web.

  • Lab Exercise – HTTP
    Lab Exercise – HTTP Objective HTTP (HyperText Transfer Protocol) is the main protocol underlying the Web. HTTP functions as a re- quest–response protocol in the client–server computing model. A web browser, for example, may be the client and an application running on a computer hosting a website may be the server. The client submits an HTTP request message to the server. The server, which provides resources such as HTML files and other content, or performs other functions on behalf of the client, returns a response message to the client. The response contains completion status information about the request and may also contain requested con- tent in its message body. A web browser is an example of a user agent (UA). Other types of user agent include the indexing software used by search providers (web crawlers), voice browsers, mobile apps, and other software that accesses, consumes, or displays web content. HTTP is designed to permit intermediate network elements to improve or enable communications between clients and servers. High-traffic web- sites often benefit from web cache servers that deliver content on behalf of upstream servers to improve response time. Web browsers cache previously accessed web resources and reuse them when possible to reduce network traffic. HTTP is an application layer protocol designed within the framework of the Inter- net protocol suite. Its definition presumes an underlying and reliable transport layer protocol and Trans- mission Control Protocol (TCP) is commonly used. Step 1: Open the http Trace Browser behavior can be quite complex, using more HTTP features than the basic exchange, this trace will show us how much gets transferred.

  • Working with User Agent Strings in Stata: the Parseuas Command
    JSS Journal of Statistical Software February 2020, Volume 92, Code Snippet 1. doi: 10.18637/jss.v092.c01 Working with User Agent Strings in Stata: The parseuas Command Joss Roßmann Tobias Gummer Lars Kaczmirek GESIS – Leibniz Institute GESIS – Leibniz Institute University of Vienna for the Social Sciences for the Social Sciences Abstract With the rising popularity of web surveys and the increasing use of paradata by survey methodologists, assessing information stored in user agent strings becomes inevitable. These data contain meaningful information about the browser, operating system, and device that a survey respondent uses. This article provides an overview of user agent strings, their specific structure and history, how they can be obtained when conducting a web survey, as well as what kind of information can be extracted from the strings. Further, the user written command parseuas is introduced as an efficient means to gather detailed information from user agent strings. The application of parseuas is illustrated by an example that draws on a pooled data set consisting of 29 web surveys. Keywords: user agent string, web surveys, device detection, browser, paradata, Stata. 1. Introduction In recent years, web surveys have become an increasingly popular and important data collec- tion mode, and today, they account for a great share of the studies in the social sciences. Web surveys have been used to complement traditional offline surveys as a less expensive form of pre-test or a mode of choice for respondents who are not willing to use “traditional” modes, such as face-to-face or telephone interviews. Along with the rising popularity of web surveys, survey methodologists have taken an increas- ing interest in paradata, which are collected as a byproduct of the survey process (Couper 2000).

  • Why Is XHTML Needed? Isn't HTML Good Enough?
    Why is XHTML needed? Isn't HTML good enough? HTML is probably the most successful document markup language in the world. But when XML was introduced, a two-day workshop was organised to discuss whether a new version of HTML in XML was needed. The opinion at the workshop was a clear 'Yes': with an XML-based HTML other XML languages could include bits of XHTML, and XHTML documents could include bits of other markup languages. We could also take advantage of the redesign to clean up some of the more untidy parts of HTML, and add some new needed functionality, like better forms. What are the advantages of using XHTML rather than HTML? If your document is just pure XHTML 1.0 (not including other markup languages) then you will not yet notice much difference. However as more and more XML tools become available, such as XSLT for tranforming documents, you will start noticing the advantages of using XHTML. XForms for instance will allow you to edit XHTML documents (or any other sort of XML document) in simple controllable ways. Semantic Web applications will be able to take advantage of XHTML documents. If your document is more than XHTML 1.0, for instance including MathML, SMIL, or SVG, then the advantages are immediate: you can't do that sort of thing with HTML. Can I just put the XML declaration on top of existing HTML documents? Can I intermix HTML 4.01 and XHTML documents? No. HTML is not in XML format. You have to make the changes necessary to make the document proper XML before you can get it accepted as XML.

  • Economic and Technical Drivers of Technology Choice: Browsers
    Economic and Technical Drivers of Technology Choice: Browsers (Working paper: please do not cite without permission from authors) Timothy F. Bresnahan and Pai-Ling Yin First Draft: Nov 05, 2003 Abstract The diffusion of new technologies is their adoption by different economic agents at different times. A classical concern in the diffusion of technologies (Griliches, 1957) is the importance of raw technical progress versus economic forces. We examine this classical issue in the modern market of web browsers. Using a new data source, we study browser brand shares and the diffusion of new browser versions. Features of that market also generate novel questions in the economics of diffusion. We find that browser distribution via the expanding market for a complementary technology, personal computers (PCs), had a larger effect on the rate and direction of technical change than technical browser improvements.

The diffusion of the new technology to the economic agents who will use it determines the rate and direction of realized technical change in the economy. We have known since the work of Griliches (1957) that both economic and technical forces shape diffusion. Invention is only the beginning of technical progress. Inventors introduce new technologies into the field and start their diffusion. The movement of the overall economy toward realizing a technological opportunity depends on the behavior of the adopters of the technology.

A classical concern in the diffusion of technologies (Griliches 1957) is the importance of raw technical progress versus economic forces. We examine this classical issue in a modern market, web browsers. Using a new data source, we study the diffusion of new browser versions. In a second analysis, we study the determination of browser brand shares. Both analyses let us examine the important of technical progress vs. economic forces. We find that the critical economic force was browser distribution with a complementary technology, personal computers (PCs). In both of our analyses, distribution had a larger effect on the rate and direction of technical change than technical browser improvements. This shows an important feedback. Widespread use of the Internet spurred rapid expansion of the PC market in the late 1990s. Our results show that the rapid expansion in PCs in turn served to increase the pace of diffusion of new browsers and thus move the economy toward new mass market commercial Internet use. Timothy F.

  • HTTP Transactions
    05 4547 ch03 1/24/03 8:44 AM Page 29 3 HTTP Transactions HTTP TRAFFIC CONSISTS OF REQUESTS AND RESPONSES. All HTTP traffic can be associated with the task of requesting content or responding to those requests. Every HTTP message sent from a Web browser to a Web server is classified as an HTTP request, whereas every message sent from a Web server to a Web browser is classified as an HTTP response. HTTP is often referred to as a stateless protocol.Although this is accurate, it does little to explain the nature of the Web.All this means, however, is that each transaction is atomic, and there is nothing required by HTTP that associates one request with another. A transaction refers to a single HTTP request and the corresponding HTTP response. Another fundamental topic related to the nature of the Web is the topic of connections. Connections When I speak of a connection in HTTP,I refer to a TCP connection.As illustrated in Figure 3.1, a TCP connection requires three separate messages. TCP SYN TCP SYN + ACK TCP ACK Figure 3.1 A TCP connection requires three messages. SYN and ACK are two flags within the TCP segment of a packet. Because TCP is such a common transport layer protocol to be used in conjunction with IP,the combined pack- et of an IP packet containing a TCP segment is sometimes called a TCP/IP packet, even though it would best be described as a packet within a packet. By this example, you can see that a connection is unlike what you might otherwise expect.After this exchange, both computers simply consider themselves connected.
