At Vidya we pride ourselves on embracing emerging technologies and helping our clients leverage them to realize their potential. This website proves we practice what we preach. We built it with Hugo, a stunningly fast static-site generator built on Google’s popular Go programming language, which continues to shoot up the Tiobe Index.

Speaking at Code Writers Workshop 2017

The Code Writers Workshop is taking place outside Washington, DC on June 9th with the theme “Software Leadership in a New Era.” The speakers are a diverse, distinguished array of industry leaders who have done great things around the world. The keynote speaker, Kara DeFrias, was Director of UX for former Vice-President Joe Biden! The surprising thing is they’re letting me speak too. I have the honor of speaking on the topic “Here’s What’s Trending in Software Engineering.

ScrumMaster++

Anyone with a basic knowledge of Scrum, and certainly everyone who has taken Agile Software Project Management With Scrum, knows the role of the ScrumMaster–to be a servant leader, to act as guardian of the Scrum process, to remove obstacles for the delivery team, to negotiate any tension between the Product Owner and the delivery team, to encourage the team to self-organize and be cross-functional, and so on. These are so well understood they’re almost clichés.

A New Strategy for Scala

Alvin Alexander is a renowned software engineer and author. His Scala Cookbook was invaluable when I got started with Scala, and that book and his prolific blog posts have remained essential reading even as I’ve gotten better at it. One of Alvin’s most recent posts, How Scala killed the Strategy Pattern, is the latest iteration of an old criticism of the Gang of Four (Go4) Design Patterns by functional programming (FP) advocates–that you don’t even need them if languages provide sufficient abstractions.

Analytics With Apache Spark Is Here

As promised earlier this year, we at Vidya are proud to officially announce our newest course Analytics with Apache Spark. Spark is a cool technology making an enormous–and growing–impact in the Big Data space, so naturally there are a lot of courses out there. Ours is different. Naturally we spend a lot of time on Spark itself with numerous code examples and challenging exercises, but we also stress the importance of things that have always mattered and still matter–architecture, security, and software engineering concepts like unit and integration testing, continuous integration, and continuous delivery.

Analytics With Apache Spark Is Coming

At Vidya we currently offer two courses, Software Engineering in Java and Agile Software Project Management with Scrum. In response to popular demand…OK, like eight or nine people…we are currently working on a third course to be ready by Summer 2015 tentatively called Analytics with Apache Spark. As “Big Data” becomes more and more of a thing, there just aren’t enough software engineers who know the tools and techniques for doing meaningful, performant, cloud-scale analytics.

DevOps Hooray

Please take a look at my latest column for Government Computing News where I drop references to Brangelina and Kimye to explain why DevOps has become so popular in business and why it needs to be a thing in government as well. Just to give you an idea, here is the unedited introduction. Terms like service-oriented architecture and big data have long been part of the pantheon of buzzwords that have captivated us while eluding any kind of real understanding.

Oracle v. Google Just Got Real

Please take a look at my latest column for Government Computing News where I describe why the biggest names in technology are getting involved in the legal battle between Oracle and Google over Android and the profound consequences this case could have for technology in the future. Just to give you an idea, here is the unedited introduction. In November, the Electronic Frontier Foundation (EFF) filed a brief with the Supreme Court of the United States asking the justices to reverse a decision involving Google and Oracle that would have profound consequences for technology if it stands.

Zero Tolerance

Experienced Java developers know that Java 5 brought many significant improvements to the language. One of them was the introduction of BigDecimal, an abstraction for arbitrary-precision decimal numbers that gives you arithmetic functionality and complete control over rounding and scale. All of this flexibility and power made BigDecimal the de facto class Java developers used to model money–at least until Java 7 gave us the Currency class. On a recent project though with an API that doesn’t use Currency, I had a simple question:

The Play's the Thing

Please take a look at my latest column for Government Computing News where I explain how to apply the guidance found in the White House’s new U.S. Digital Services Playbook, which embraces agile software development and open-source for building better government applications. Just to give you an idea, here is the unedited introduction. Software engineering is my passion--not just the technologies but the art of building software the right way.
