Open Source Conversations
IT Conversations publishes a number of shows that deal with free and open source software. We've created this channel as a way of helping people interested in open source software find talks, discussions, presentations, and interviews about that topic.
All systems suffer from failures, but less frequently than expected. Why is it we have so few accidents in a world that behaves so badly? Dr Richard Cook speaks to this issue and what we learn from it based on twenty-five years of research beginning with the medical field in emergency rooms, surgical theaters and application of anesthesia. His scope then expands to other complex systems in such critical and dangerous human endeavors as aviation, power generation and distribution, and military operations.
Over 25 million downloads in 2011 support calling PhET Interactive Simulations the leading provider of educational physics simulations. In this audio interview, Sheela Sethuraman speaks with Katherine Perkins, Director of PhET since 2008. As The Tech Awards 2011 laureates of the Microsoft Education Award, Perkins discusses how PhET has continued to grow and adapt their simulations for a growing audience in recent years.
Artur Bergman, CEO of Fastly, tells everyone what he really thinks about ops software offerings and their marketing. Given the state of things, it's important for any ops manager to be a generalist, and be ready to delve into understanding the nuances of distributed systems to fix underlying problems that cause delays and loss of traffic. Months after this talk, Bergman made tools available on GitHub, beginning to cover the scope of things to know for optimum operations. Warning: Strong Language.
Google wants to make the Web faster. Arvind Jain and Sreeram Ramachandram from Google unveil Chrome Instant, a new feature built right into Google's browser Chrome, to make your search results load faster. With Chrome Instant enabled, Google makes an intelligent guess about which search result you are most likely to click on, and pre-loads that search result into a new, hidden tab in Chrome. If you do click on the search result, the hidden tab is unhidden, creating the illusion of an instant browsing experience.
For robotics to become ubiquitous, the key is a simple efficient connector. Organic chemistry is a simple self-reconfiguring process which inspired Tom Larkworthy to emulate it in self-reconfigurable robots. Larkworthy's pragmatic work focuses on a lattice arrangement, a hexagonal metamorphical robot with a simple set of local motion constraints. Per Sjöborg and Larkworthy discuss how gender, simplicity and limits contribute to efficiency in self-reconfigurable robots.
For Patrick Lightbody, sometimes it is entirely appropriate to kill a fly with a sledgehammer. Of course, that was one of Lightbody's breakthrough innovations when he founded Browser Mob. His other was relying upon Amazon Web Services. In this keynote address, Lightbody explains how depending upon AWS allowed him to focus entirely on his core business. He also shares four lessons he gained from growing his startup company on the cloud.
One of the aspects of software development that has grown in importance is the need for quality testing of new products as part of the overall process. James Whittaker, co-author of How Google Tests Software, discusses how his former company built a successful model based on the vital testing of its new services. He reviews how testing has grown as part of development and the different testing roles that Google used. His points clearly show how developers need to consider the importance of testing as a role for the developer.
Paul Querna gives a quick summary of an ongoing open source project called Cast written in Node.js. It is a framework for deploying applications. Cast provides tools for system administrators and developers to create, deploy, maintain, and monitor distributed services written in any language. The internals are structured around building RESTful APIs for all operations, so all tasks can be scripted and more powerful tools built on top. Web locations are provided and collaborators encouraged to visit.
Speech technology expert and noted author Moshe Yudkowsky laments, " ...the models and information required by speech technology is simply too great for today's open source collaborations." Yudkowsky discusses the practical edge of speech technology, covering solutions for both large and small businesses.
