ABSTRACT

SVG is an XML vector graphics standard that is gaining momentum on the web. It is supported by most browsers (IE with a plug-in) and fills a need for vector graphics in the high resolution environments that webpages are finding themselves in while still providing graphics rich experiences to mobile users with smaller file sizes. This talk will go into the SVG standard and how to easily make SVG documents using Inkscape. Inkscape is a cross-platform Open Source vector drawing tool that is based on the SVG standard.

Tyler Close

Visiting Scientist Hewlett-Packard Laboratories

Mr. Close is a researcher and developer, working in the field of secure, multi-user, distributed applications since 1998.

ABSTRACT
In Authorization Based Access Control (ABAC) systems built with object-capabilities, an access policy is expressed by the shape of a reference graph: what a user can do is determined by where they are in the reference graph and what other parts of the graph are reachable from that point. By applying some basic cryptography to create links that act as "webkeys", we can construct URL graphs that are compatible with today’s WWW infrastructure and additionally provide the properties of distributed capabilities. Webkeys enable users to achieve password-free fine-grain access control implicitly, simply by sending one another links to the pages they want to share. The webkey approach simultaneously provides developers with a powerful, and readily audited, access-control model.

In this talk, we’ll study the implementation of the CapWiki, which can serve as a private data space, a locally shared data space, a blog, and a wiki, simply by varying which links have been distributed to which people. Read the rest of this entry »

Open Source Speaker Series: Practical MythTV

Google Tech Talks
August 16, 2007

ABSTRACT

MythTV is a powerful open source personal video recorder. It records television off the air, plays downloaded media files, DVDs, and audio files. It also includes a web browser, RSS reader, weather applet, and much more. During this talk Michael will introduce MythTV, show off the frontend interface, MythWeb, talk about the current challenges with guide data in the United States, and discuss some of the upcoming features. Michael is a coauthor of "Practical MythTV", which was published in April 2007.

Michael Still is currently a Site Reliability Engineer at Google. Before that, he was a senior software engineer at TOWER Software in Australia. For many years he has been using his spare time to work on open source projects of various forms. This includes a book on ImageMagick in 2005, and a book on MythTV in 2007.

15 Views of a Node Link Graph: An Information Visualization Portfolio

Tamara Munzner received a BS in 1991 and a PhD in 2000 from Stanford. Her current research interests are information visualization, graph drawing, and dimensionality reduction. She was the IEEE Symposium on Information Visualization Program/Papers Co-Chair in 2003 and 2004.

ABSTRACT
Information visualization, or infovis, is the interactive computer-based visual representation of abstract datasets. I will use collections of linked nodes as the launching point for a discussion of fifteen different approaches to infovis. Node-link graphs appear in many application domains, and people can perform many tasks faster or more effectively when they can manipulate a well-chosen visual representation of these graphs. A major challenge within infovis is how to handle the large datasets that occur in the real world. Designing algorithms with scalable speed and memory complexity is only part of the solution. The visual representation must also provide an appropriate abstraction, often requiring exploration across multiple levels of detail, to be comprehensible to the human in the loop. The talk will include examples in application domains ranging from web browsing to bioinformatics to computational linguistics, and datasets from thousands to millions of items.

Quicksilver: Universal Access and Action
Google engEDU
25 min – Aug 30, 2007

Google Tech Talks
August 30, 2007

ABSTRACT

Quicksilver hides almost unbounded power beneath the interface of a keyboard-driven launcher. Using a basic grammatical model, it allows you to move beyond basic search and work effortlessly with applications, data, and the web. Quickilver is above all a prototype intended to explore new forms of interaction.

In this talk, we will explore the motivation behind Quicksilver, highlights of its implementation, lessons learned from its design, and the ways it might inform the future of navigation for the desktop and the web.
