It went from non-existence to global adoption in an alarmingly short period of time. It never had an interval in the lab when it could be tried out and polished. JavaScript has some extraordinarily good parts. In JavaScript there is a beautiful, highly expressive language that is buried under a steaming pile of good intentions and blunders. The best nature of JavaScript was so effectively hidden that for many years the prevailing opinion of JavaScript was that it was an unsightly, incompetent abomination. This session will expose the goodness in JavaScript, an outstanding dynamic programming language. Within the language is an elegant subset that is vastly superior to the language as a whole, being more reliable, readable and maintainable.

Erlang was developed with goals such as high-availability, \"prototypeability\"/maintainability and scalability over an at design time unknown number of CPUs. All goals are still challenges in software development. The scalability property has however reached another dimension due to the past few years development in the field of common and affordable multi core processors. This talk will cover the history of Erlang, demonstrate major design goals with a few programming examples and also touch on the subject of the future of Erlang.

Switch statements? Do you have the same switch statement in various places? When you make changes do you find yourself making the same change to the same if/switch in several places? Did you ever forget one? This talk will discuss approaches to using Object Oriented techniques to remove many of those conditionals. The result is cleaner, tighter, better designed code that\'s easier to test, understand and maintain.

More specifically: How can our time connected via technology enhance our creativity and well-being instead of adding to our frustration and stress? How can we engage creatively with our work such that we are more likely to calmly complete a project in four hours rather than stressing and banging our head to complete it in eight? How can our time connected be more focused and less scattered? In this talk, focused on Stress Relief for the Creative and Constantly Connected, teachings from ancient wisdom traditions like Zen will be used to address these questions. Using material from his forthcoming book on this subject, the speaker will offer tools for living sanely and effectively in this increasingly connected world.

We have the functional manager and the project manager, the scrum master and the black belt, the product owner and the customer-on-site, the technical leader and the architect, the product manager and the chief engineer. Clearly that\'s too many leaders. So how many leaders should there be, what should they do, what shouldn\'t they do, and what skills do they need? This will be a presentation and discussion of leadership roles in software development -- what works, what doesn\'t and why. Speaker: Mary Poppendieck Mary Poppendieck started her career as a process control programmer, moved on to manage the IT department of a manufacturing plant, and then ended up in product development, where she was both a product champion and department manager. Mary considered retirement 1998, but instead found herself managing a government software project where she first encountered the word \"waterfall.\" When Mary compared her experience in successful software and product development to the prevailing opinions about how to manage software projects, she decided the time had come for a new paradigm. She wrote the award-winning book Lean Software Development: An Agile Toolkit in 2003 to explain how the lean principles from manufacturing offer a better approach to software development. Over the past six years, Mary has found retirement elusive as she lectures and teaches classes with her husband Tom. Based on their on-going learning, they wrote a second book, Implementing Lean Software Development: From Concept to Cash in 2006. A popular writer and speaker, Mary continues to bring fresh perspectives to the world of software development. Thu, 22 Jan 2009 15:01:30 UT http://www.geeksww.com/videos/display/26/the_role_of_leadership_in_software_development.php http://www.geeksww.com/videos/display/25/seattle_conference_on_scalability_giga_scalable_directori.php Traditionally file system designs have envisioned directories as a means of organizing files for human viewing; that is, directories typically contain few tens to thousands of entries.Users of large, fast file systems have begun to put millions of entries in single directories, probably as simple databases. Furthermore, many large-scale applications burstily create a file per compute core in clusters with tens to hundreds of thousands of cores. This talk is about how to build file system directories that contain billions to trillions of entries and grow the number of entries instantly with all cores contributing concurrently. The central tenet of our work is to push the limits of scalability by minimizing serialization, eliminating system-wide synchronization, and using weaker consistency semantics. We build a distributed directory index, called GIGA+, that uses a unique,self-describing bitmap representation that allows the servers to encode all their local state in a compact manner and provides the clients with hints required to address the correct server. In addition, GIGA+ also handles operational realities like client and server failures, addition and removal of servers, and \"request storms\" that overload any server. I\'ll describe the implementation of our prototype in the PVFS2 parallel file system and experimental evaluation that demonstrates high degree of scalability. (this is joint work with Garth Gibson at CMU) Thu, 22 Jan 2009 14:49:29 UT http://www.geeksww.com/videos/display/25/seattle_conference_on_scalability_giga_scalable_directori.php http://www.geeksww.com/videos/display/24/seattle_conference_on_scalability_scalable_wikipedia_with_e.php IGlobal online services at Amazon, eBay, Myspace, YouTube, or Google serve millions of customers with tens of thousands of servers located throughout the world. At this scale, components fail continuously and it is difficult to maintain a consistent state while hiding failures from the application. Peer-to-peer protocols provide availability by replicating services among peers, but they are mostly limited to write-once/read-many data sharing. To extend them beyond the typical file sharing, the support of fast transactions on distributed hash tables (DHTs) is an important yet missing feature. We will present a distributed key/value store based on a DHT that supports consistent writes. Our system comprises three layers: - a DHT layer for scalable, reliable access to replicated data, - a transaction layer to ensure data consistency in the face of concurrent write operations, - an application layer with an extremely high access rate. For the application layer, we selected a distributed, scalable Wiki with full transaction support. We will show that our Wiki outperforms the public Wikipedia in terms of served page requests per second and we will discuss how the development of the distributed code benefited from the use of Erlang. This is joint work of Zuse Institute Berlin and onScale solutions GmbH.

He then founded Namesys in 1993 when he went to Russia and hired a small team of programmers to implement the storage layer for these semantics, known as the Reiserfs filesystem for Linux. He spent 5 years arguing over algorithms on evenings and weekends, and working day jobs in Silicon Valley, and then finally the code started to work well enough that he could quit the day jobs.

NetTrust combines an implicit and explicit means of data collection. This trust based system uses shared browsing histories from a user's self-selected social networks to create both explicit and implicit data collection. NetTrust targets the human element of trust. It projects how a social network can signal meaningful trust information that can make an educative browsing experience. NetTrust allows an individual to select their own trusted sources of information and rate particular sites as trustworthy (or not). NetTrust allows an individual to select their own trusted authoritative sources of information from a market of ratings agencies and combine these ratings with the reputation information from their individual social network. This paper will present the Net Trust system; the dorm-based homophily tests with implications and the undergraduate-focused user testing. Speaker: Professor L. Jean Camp Professor L.

Apple's SDK for the iPhone is based on Objective-C as the development language as well as Cocoa for the GUI. Unfortunately Apple's license agreement for the iPhone SDK prohibits the porting of the Java virtual machine to the iPhone. In this presentation we introduce an Open Source Java-to-Objective-C cross-compiler as well as a Java-based implementation of the Cocoa library. With the help of these tools, iPhone applications can be written in pure Java. Using the Java version of Cocoa, it is possible to run a Java-based iPhone application as a Java desktop/applet application that can be cross-compiled to run natively on the iPhone. The talk will discuss the challenges of the Java-to-Objective-C cross-compiler as well as the Java-based version of Cocoa.

Finally, it will go into why companies like Google, and any other that uses or depends on Linux, should care about this development. Lots of numbers and pretty graphs will be shown to keep the audience awake. Speaker: Greg Kroah Hartman Greg Kroah-Hartman is a Linux kernel maintainer for the USB, driver core, sysfs, and debugfs portions of the kernel as well as being one half of the -stable kernel release team. He currently works for Novell as a Fellow doing various kernel related things and has written a few books from O'Reilly about Linux development in the past.

These best practices have proven to reduce response times of Yahoo! properties by 25-50%. They focus on the front-end, for example, why it's bad to use "@import" for including stylesheets and why ETags disable browser caching. In this talk I'll go in-depth on these best practices and the research behind them. I'll also demonstrate YSlow and do some live performance analysis of popular web sites.

Examples include inferring social networks from communication data, identifying gene regulatory networks from protein-protein interactions, etc. On the flip-side, there is a growing interest in anonymizing social network data, and understanding the different types of privacy threats inherent in relational data. In this talk, I will discuss some of the key processes involved in identification (entity resolution, link prediction, collective classification and group detection) and I will overview results showing that on several well-known social media sites, we can easily and accurately recover information that users may wish to remain private.
