Wearable Computing Wearable computing is coming to the masses in the forms of fitness, gaming, and medical devices while non-consumer markets such as defense and aerospace continue to push for advanced wearable technologies to enhance safety, mobility, and efficiency in places most people will never go. Here are some recent examples of the state-of-the-art technology in wearable computing and then some that, with a little tech-know-how, you can make at home: Intel Battles Parkinson’s Disease with Big Data and Wearable Tech: Mike Wheatley at Silicon Angle describes a new project at Intel, in which a Big Data analytics platform combined with a wearable device will produce a better record of symptoms experienced by Parkinson’s patients . The Inside Story of the Oculus Rift: Peter Rubin at Wired reports that, with the Rift, Oculus hacks the visual cortex to make a virtual-reality headset that doesn’t cause “cold sweat syndrome.” The Cardboard Project: Google Developers show how you can build your own basic VR headset with a smartphone and some basic items that you can get at the hardware store. Raspberry Pi GPS Helmet Cam: Martin O’Hanlon at Stuff About Code used his Raspberry Pi­-based car cam to develop a helmet cam, takes it snowboarding, and record data about speed, altitude, and temperature.  

Test-Driven Development: Dead or Alive? Back in the Spring, a single blog post sparked a debate that on the surface seems absurd. Is TDD actually useful and still relevant? The discourse that followed and is still following this discussion is spectacular and spans Twitter, blogs, and a series of video debates. We thank Michael Keeling of Never Let Down for bringing this debate to our attention. TDD is dead. Long live testing.: David Heinemeier Hansson, the creator of Ruby on Rails, discusses the death of test-driven development and the need to transition from unit testing to system testing. Is TDD Dead?: Martin Fowler engages Hansson and Kent Beck in a series of video conversations on the topic of test-driven development and its impact on software design, including confidence, test-induced design damage, and cost.

by Rey Hernandez Sony Network Entertainment International @DeveloperRey Many times in a project, software or otherwise, the people working on the project become so entrenched in the methods they find familiar that they allow roadblocks to get in the way of project completion. All too often those roadblocks lead to missed deadlines, cut corners, general reduction in team morale, and ultimately a product that does not meet customer expectations. In his keynote at SATURN 2014, Joe Justice of Team Wikispeed and Scrum Inc., treated us to a refreshing view of project management that illustrates how teams can be extremely productive, with high morale, and great customer satisfaction.

The Cloud The Future Looks “Foggy” for Cloud Computing: Greg Otto at FedScoop reports on cloudlets and cyberforaging, potential solutions for bandwidth problems at the edge of the cloud, from a talk given by the Software Engineering Institute’s Grace Lewis at the Federal Cloud Computing Summit. Virtual Machines, JavaScript and Assembler: In a keynote presentation at the 2014 O’Reilly Velocity ConferenceScott Hanselman “explores the relationship between the cloud and the browser, many languages and one language, how it might all fit together, and what comes next.” SMBs Tie Cloud Computing To Increased Revenue: Charles Babcock at InformationWeek reports on research by Oxford Economics and Windstream Communications that found that small and midsized businesses credit cloud computing with increasing revenues. The Uneven Future: 2 Telling Views of Cloud Adoption: Bernard Golden at CIO gives three reasons for the uneven growth of cloud computing.

by Anthony Tsakiris Ford Motor Company Architecture development activities as presented in books, articles, and classes are sometimes “heavy” – that is, they require a lot of time and people resources relative to what is available. That’s my view from an automotive embedded-control-systems environment. An argument can be made that that’s what it takes, but there’s another reality that time and resources are truly in short supply. It’s difficult to get stakeholders who are busy with multiple projects and production concerns to commit big chunks of their time to an activity like a Quality Attribute Workshop for a new project.

by Russell Miller Vice President of Technology Services at Co-host of Architectural Concepts podcast At SATURN 2014 there were a number of excellent sessions on DevOps and Continuous Delivery; one of those was Dianne Marsh’s keynote entitled, “Engineering Velocity: Continuous Delivery at Netflix.” Dianne is the director of engineering tools at Netflix, a company that has led the way in terms of continuous delivery. Dianne’s main objective for the talk was to share details and philosophy from Netflix that the audience could consider for application in their organizations as a means to improve their velocity. She did a great job achieving that objective.
