Link Roundup, 9/2/14: DevOps: Definitions and Misconceptions

DevOps: Definitions and Misconceptions

This month, Ben Kepes at Forbes reported on ScriptRock’s efforts to raise funding from investors to expand their operations in “To Help DevOps-ify The World.” Kepes opens with an explanation of how ScriptRock must first differentiate its product and services from vendors selling “DevOps in a box.” More agile software development in less time, however, may not fit neatly in that box. Here are some links to definitions of DevOps that include components that exist outside of the box.

Defining DevOps Might Be Harder Than Defining Design: In the Under Development podcast series, Bill Higgins and Michael Coté explain DevOps, metrics, and “the processes used by designers vs. software developers vs. management consultants vs. wedding planners.” Continue reading

Link Roundup, 8/14/14: Test-Driven Development: Dead or Alive?

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. Continue reading

Rey Hernandez on For Maximum Awesome, Joe Justice SATURN 2014 Keynote

by Rey Hernandez

@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.

Link Roundup, July 29, 2014: The Cloud

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.

Anthony Tsakiris on Facilitating the Mini Quality Attributes Workshop, Will Chaparro and Michael Keeling, SATURN 2014 Presentation

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.

Vice President of Technology Services at Impulse.com
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.

Podcast: Amazing Architectures Don’t Happen by Accident

At the Architectural Concepts Podcast, SATURN 2014 Technical Chair Michael Keeling discusses techniques for exploring and uncovering the shortest path to amazing architectures, mapping the idea of design modes to software architecture.

In the podcast, Michael also discusses the rapid software architecture workshop, based on these ideas, that he delivered at SATURN 2014.
