Backing Up's Not Hard to Do

GreenData.jpg You don’t have to be a fan of Sex in the City to know that it’s important to backup your data. If you have not seen this wonderful vignette, take a moment to see what can happen if your intellectual property is not well protected.

Princeton uses a software application called Tivoli Storage Manager or TSM to back up campus computers. During the current academic year, TSM has backed up 600,000,000,000,000 bytes of stored data on 10,849 campus client accounts using 16 STK/Sun T10000 encrypted tape drives in two silos as well as eight TSM servers in two computer rooms.

Computer Modeling of the Mind and Brain

BrainMap.jpgFor those who still assume that the Psychology faculty analyze subconscious thoughts and place rats in mazes, Matthew Botvinick represents an eye opening cup of java. Building on the foundations of cognitive psychology, Botvinick’s laboratory works at the intersection of neuroscience, psychology and computer science, seeking to clarify the computational and neural foundations of human behavior. They employ a diverse set of research tools, including functional neuroimaging (fMRI), behavioral techniques (reaction time, error, and decision analyses), and computational modeling (neural networks, reinforcement learning models, and belief nets), typically applying multiple techniques to a single problem.

They are leveraging these tools to investigate a range of specific research questions, spanning the topics of cognitive control, working memory, decision making, sequential action, and language processing. Current projects include the monitoring and control of cognitive processing, the control of sequential behavior, and the representation of sequential order in working memory.

The Cairo Geniza: Ancient Papers in the Digital Age

GenizaPaper.jpg The Cairo Geniza is a collection of an estimated 750,000 manuscript pages found discarded for “burial” in the Geniza chamber of the Ben Ezra Synagogue in Cairo in the late 19th century. In addition to holding religious poems and fragments of Torah scrolls, the Cairo Geniza contains approximately 15,000 mundane papers that reflect the daily life of the Jewish community in Cairo during the medieval period (mainly in the 11th to 13th centuries) - letters, contracts, wills, and other legal documents preserved in the area’s arid climate. These “Geniza documents” range in size from a few words to long letters of 80-100 lines.

For more than two decades, Mark Cohen and his Princeton colleagues have been working to bring these ancient papers into the digital age. Their work, called the Princeton Geniza Project, has created the world’s only online, searchable-text database of the Cairo Geniza’s historical documents.

Archives and Manuscripts: Library Finding Aids

FAbook.jpgThe Department of Rare Books and Special Collections at the Princeton University Library holds world class archival and manuscripts collections. The Mudd Manuscript Library, with more than 35,000 linear feet of storage, holds two major collections: The Princeton University Archives and “Public Policy Papers” which include very significant collections in the areas of foreign policy, economics and economic development, Civil Liberties, Law and Jurisprudence.

Finding aids, descriptive inventories created by archival repositories in order to provide access to collections, serve as the entry points for scholars and researchers to discover and explore these collections. In order to provide a standard structure for finding aids, the archival community developed an international XML metadata standard, Encoded Archival Description (EAD) in 1995. Comparable to AACR2 and MARC for bibliographic records, the content standard for Finding Aids has now been adopted by numerous institutions. EAD reflects the hierarchical nature of archival collections and provides a structure for describing the whole of a collection, as well as its components. And the standard supports flexible searching by collection, creator, biographies, title, call number, or topic.

Flash Forward: The Rise of Small Tech Gadgets

gadgets.jpgA compelling technology, flash memory continues its march through the consumer electronics industry, yet again doubling quickly in capacity and dropping in price. In its wake, the wreckage of other, once proud, technologies and products — the floppy disk wiped from computers by the USB drive, the CD Audio disc humbled by portable flash players, and tape-based video cameras that now seem clunky compared to smaller flash cams. And next in the sights: computer hard drives giving way to faster and more rugged Solid-State devices.

Again this year, Doug Dixon of Manifest Technologies worked the January Consumer Electronics Show to scope out the new products. This year’s show saw even more examples of the impact of flash memory: rugged HD camcorders, replacement solid state storage devices, Wi-Fi integrated on SD memory cards, new formats promising 2 terabyte memory cards, and card slots everywhere, from mobile phones to HDTV displays. Dixon returned to Lunch ‘n Learn on April 15 to explore the developing trends in the rise of flash memory and to show off dozens of fun, new, high-tech gadgets. His web site, contains his Lunch ‘n Learn presentation, as well as more than 200 additional articles and a blog about a range of technology topics. The site also contains more detailed information about the products that Dixon demonstrated during his talk.

All Aboard! Teaching Engineering with Computerized Toys

train.jpgImagine being paid, or getting Princeton credit, for playing with trains and Legos™.

For more than 25 years, Professor Michael G. Littman, of Mechanical and Aerospace Engineering at Princeton, has taught MAE 412 Microprocessors for Measurement and Control, a course about microcomputer control.

In the class, students design single-board microcomputer controllers, and apply them for the automation of a modular n-scale model railroad. For example, a computer might be used to automate railroad switches to prevent collisions, facilitate traffic flow through a ladder network of tracks on a project board, or even regulate the loading of pipes onto train cars.

The Foundations and Future of Information Search

search.jpg Launched in 1998, Google’s stated its mission: “to organize the world’s information and make it universally accessible and useful.” And so it is. Today, everyone Googles - in the U.S, about 12 billion times a month (including search engines that aren’t Google). We are mostly pleased with the results we get. How can it be that we give an automated system a couple of words and it finds reasonably relevant documents among one hundred billion or so possibilities? Will our satisfaction with these tools increase or decrease as the Web and our expectations grow?

At the March 4 Lunch ‘n Learn seminar, Computer Science Professor Andrea LaPaugh gave a peek “under the hood” of major search engines. Core techniques range from word occurrence analysis for text documents, which originating in the 1960s, to Web linking analysis, pioneered by Google’s 1998 PageRank document ranking method.

Sam Wang: Election Predictions and More

SamWang.jpg Having highlighted his work in a previous post, we invited Professor Sam Wang to speak at Lunch ‘n Learn on February 11. He graciously forwarded the following thoughts:

It was great fun to be invited to give the first Lunch ‘n’ Learn talk this spring. My topic was the ups and downs of Campaign 2008, and the understanding that statistical geeks can bring to the process. I also put on my neuroscience hat and got into how and why people form false beliefs, especially political ones. The audience was great and the questions were interesting.

Computational Intractability: A Barrier for Computers, Man, and Science

locksilverside.jpgWhile computers are exponentially more powerful and increasingly important in both society and in every area of scholastic inquiry, modern computers appear to be incapable of solving certain problems. In recent decades, computer scientists have begun to develop an understanding of what makes some computational tasks “intractable” not just for current computers but for all foreseeable computers, even if they were joined together.

Princeton is the lead institution for a new $10 million National Science Foundation grant for the study of computational intractability. At the Dec 10 Lunch ‘n Learn seminar, Sanjeev Arora, the principal investigator on the new grant, Professor of Computer Science, the Director of the Center for Theoretical Computer Science, and the Director of the Center for Intractability gave an overview of both the field and what the new center is trying to accomplish.

Challenging Nature

cornana.jpg Professor Lee Silver gets around. He’s discussed cloning with Charlie Rose, stem cells with Ted Koppel, and designer babies on the BBC. You can even watch him tangle with Stephen Colbert. A professor at Princeton in the Department of Molecular Biology and the Woodrow Wilson School of Public and International Affairs, Silver’s most recent book is Challenging Nature: The Clash of Biotechnology and Spirituality. According to one reviewer, he “gleefully eviscerates the motley preachers, pundits, philosophers, and politicians who, he argues, hinder science on the basis of a vague belief that biotechnology trespasses where mere mortals dare not go.”

E-books: Princeton and Beyond

KindleCoffee.jpg When e-books began to appear in the early 2000’s, there was speculation about the demise of the printed book. While that clearly did not come to pass, e-books have now become a staple of the reference holdings of many libraries. The library and consumer markets have matured, and despite all predictions and speculations, print books and e-books have continued to co-exist quite nicely at the Princeton University Library.

At the December 3, 2008 Lunch ‘n Learn Adriana Popescu, Princeton’s Engineering Librarian and Plasma Physics Librarian, and Priscilla Treadwell, Electronic Publications Marketing Manager at the Princeton University Press, presented both the library and publisher perspectives: Princeton University Library’s selection process for e-books, and the usage patterns at the University that reveal what readers in an academic environment like and don’t like about e-books; and Princeton University Press’s rationale for making certain content available to both the library and consumer markets.

Das Café: Technology in the Language Classroom

Das Café Two technology-driven projects at Princeton are improving teaching and learning in beginning German. Jamie Rankin, coordinator of language teaching and pedagogy and a senior lecturer in the department since 1991, introduced both approaches at a November 19 Lunch ‘n Learn seminar.

The first project is a database that provides teaching resources for graduate student instructors. The database links the syllabus with day-by-day teaching ideas and digitized materials. As a result, even first year instructors with limited teaching experience can develop a feel for the rhythm and pulse of a class, while making pedagogical choices based on their individual classroom experience. Students gain access to these materials as well as past tests for practice.
