Conscript Your Friends into Larger Anonymity Sets with JavaScript

We present the design and prototype implementation of ConScript, a framework for using JavaScript to allow casual Web users to participate in an anonymous communication system. When a Web user visits a cooperative Web site, the site serves a JavaScript application that instructs the browser to create and submit "dummy" messages into the anonymity system. Users who want to send non-dummy messages through the anonymity system use a browser plug-in to replace these dummy messages with real messages. Creating such conscripted anonymity sets can increase the anonymity set size available to users of remailer, e-voting, and verifiable shuffle-style anonymity systems. We outline ConScript's architecture, we address a number of potential attacks against ConScript, and we discuss the ethical issues related to deploying such a system. Our implementation results demonstrate the practicality of ConScript: a workstation running our ConScript prototype JavaScript client generates a dummy message for a mix-net in 81 milliseconds and it generates a dummy message for a DoS-resistant DC-net in 156 milliseconds.Comment: An abbreviated version of this paper will appear at the WPES 2013 worksho

A descriptive and evaluative bibliography of mathematics filmstrips.

Submitted by A.W. Clark and R.W. Allen for the degree of Master of Arts and by C.H. Gardner and R.F. Sweeney for the degree of Master of Education. Thesis (Ed.M.)--Boston UniversityThe purpose of this paper is to present in one volume (1) a bibliography of all mathematics filmstrips from those suitable for the first grade to those suitable for use in senior high school and college, (2) an accurate description of each filmstrip, and (3) unbiased evaluations of each filmstrip by qualified teachers invited to take part in the project. Concomitant problems. The foregoing three parts were the heart of the problem and the portion nearly completely solved. There were, however, concomitant problems which have been partially solved by this work. The first of these concerns the limited use of filmstrips by mathematics teachers. Undoubtedly many do not believe in using filmstrips in mathematics classes. Others have never given serious thought about the advisability of using filmstrips. In later sections of this chapter and throughout this work evidence is cited to support the contention that filmstrips should have serious consideration, and that they are useful in mathematics classes. The second concomitant problem concerns the revision of current filmstrips and production of new ones. The filmstrip producers were supplied, upon their request, with summaries of the evaluations. Summaries were supplied only at the producer's request; for unless they were interested enough to request the summaries, they probably would not be interested in changing or improving their filmstrips. Summary. The problem, then, had three major parts: listing , describing, and evaluating mathematics filmstrips, and two concomitant parts: arousing the mathematics teacher's interest in filmstrips, and encouraging producers to make better productions and necessary revisions in current productions.

The New American Gazette: Henry Kissinger with Gerald R. Ford at Ford Hall Forum, transcript

Nobel Peace Prize laureate and former Secretary of State Henry Kissinger reviews domestic affairs and world events with former President Gerald Ford. They discuss U.S. foreign policy, issues facing the Soviet Union, and the situation of reform in China. The forum was recorded at the Gerald R. Ford Foundation in Grand Rapids, Michigan and broadcast on the New American Gazette radio. The program was introduced by host Marvin Kalb.https://dc.suffolk.edu/fhf-av/1005/thumbnail.jp

Guide to cataloging slotMusic based on AACR2 Chapters 6 and 9

In September 2008 SanDisk announced it would begin making music available for purchase on its microSD flash memory card format.1 The audio files on a slotMusic card are in MP3 format and are offered free of any digital rights management controls. In addition to containing an album\u27s worth of music (i.e., a slotMusic release generally corresponds to a collection of music issued on other formats such as compact disc), a typical slotMusic card may come pre-loaded with images, video, text, MIDI files, etc. Each card contains 1 GB of memory (well more than what is required for the pre-loaded content) and the extra memory can be used in whatever way the buyer wishes. Indeed, the preloaded content can be moved to another storage device and the memory card can be formatted and used like any other card. Music on slotMusic cards can be accessed using any device that both accepts microSD cards and is able to play MP3 files at up to 320 kbps.2 In addition, some slotMusic cards come packaged with a special microSD-to-USB adapter, which makes it possible to load slotMusic content onto a computer, car stereo, or any other device equipped with a USB jack. Some slotMusic cards are also sold as bundles, which in addition to the memory card and USB adapter include special dedicated MP3 players that accept the microSD format. Many early media responses questioned whether there would be a market for slotMusic, reasoning that music consumers interested in MP3s generally are comfortable with downloading them through computer network connections.3 But a more recent report in the Los Angeles Times argues that the format is doing better than many expected.4 Still, in April 2010, a search for “slotmusic” in WorldCat retrieves only the record created by this task force as an example, and it is unclear whether any libraries have begun collecting this new format. In terms of cataloging, slotMusic offers a number of challenges. Like much electronic media, the cards exhibit aspects of more than one format, in this case at least sound recordings and electronic resources. Currently, and as the name implies, slotMusic only offers musical sound recordings, but future releases could potentially contain non-musical sound. SlotMusic releases contain no descriptive information on the card itself, making choice of chief sources of information challenging. And slotMusic releases often come bundled with peripheral items (such as USB adapters and MP3 players) that contain no intellectual content, making for interesting accompanying materials notes. And finally, since the devices that can play the cards are numerous, but the technical requirements of those devices are complex, clear notes regarding the playback characteristics of the cards are necessary
