What is DevOps?

DevOps, the word, is a mash-up of the words: development and operations. Traditionally, development teams are responsible for producing software systems. And, operations teams are responsible for deploying and managing software systems.

DevOps combines those traditionally separate functions into one delivery team that has a single goal of delivering value to customers.

DevOps is Lean

Gene Kim, an author on DevOps topics and founder of Tripwire, suggest DevOps is the "result of implementing Lean principles to the IT value stream".

Consider the five lean principles:

Testing "Units"

This is a post about unit testing. I will describe some methods of automating unit tests after I have described the process of defining units.

According to Martin Fowler, an author on agile development methodologies, the definition of a "unit" has been vague since the very beginning.

There were definitional concerns about XP's use of unit testing right from the early days. I have a distinct memory of a discussion on a usenet discussion group where us XPers were berated by a testing expert for misusing the term "unit test."

In the same article, Fowler details some differences in what people consider to be a "unit".

#Notes from the keynote

##OS X Yosemite

• Master salesmanship of Windows 7 Aero-like effect on the windows
• Great new layouts for included apps like Calendar and iMessages
• Spotlight takes the utility out of tools like QuickSilver and Alfred
• Spotlight is "Google Search on the desktop" leaving the user less of a reason to launch a web browser
• Spotlight is a user-behavior-changing-feature in that users will use the web browser less (as a starting point for research)

#Gherkin Guidelines to documenting features, user stories, and scenarios using Gherkin, a business specification language.

In some projects, we will use Gherkin to communicate about features. Gherkin is a business-friendly language that is intended to ease communication between technical resources and project stakeholders.

##Feature A feature is a description of a key system function that delivers value to one or more stakeholders and/or end users.

##User Story A user story is a standard way of describing a feature in a matter that:
