I want to raise awareness of a simple mistake that can be made with the successful method of a Scala Future. A Future is a placeholder object for a value that may not yet exist. It is used for performing operations concurrently, in a non-blocking manner, and it enables scaling…
I expand on these concepts in my Reactive Summit presentation. In the first article of this series, I demonstrated the most basic patterns for integrating Akka Actors and the Akka Streams API. In the second article, I began developing an example to show how actors compliment streams, providing fault-tolerance and…
When you work in engineering or operations, you become intimately familiar with the challenges of technical debt. It can be difficult, however, to communicate the full cost of technical debt to others in the organization, particularly to people who are non-technical. Communicating the latent risks for software systems that are…
I expand on these concepts in my Reactive Summit presentation. In the first article of this series, I described the basic patterns for interfacing the Akka Streams API and Akka Actors. In the second article, I focused on how Akka Actors compliment the Akka Streams API with regard to the…
I expand on these concepts in my Reactive Summit presentation. In part one of this series, I described the challenges of integrating the Akka Streams API with Akka Actors. I demonstrated the basic patterns for interfacing streams and actors, removing the discontinuity between the two. In this article, I will…
A year ago, I accepted a team lead position. As I wrote at the time, I have had a number of opportunities to be a team lead, but I have always declined them, choosing a more technical role, to become a better engineer. In this essay, I will reflect on…
I expand on these concepts in my Reactive Summit presentation. Most people are attracted to Akka with the promise of the actor model providing a better abstraction for building scalable and resilient distributed systems. Since Akka attempts to solve such a challenging set of problems—from concurrency, to distributed…
I expand on these concepts in my ScalaDays presentation in Berlin and New York. I have spent my entire career building infrastructures for streaming data to support the monitoring and control of industrial applications. I have experience building distributed systems for data acquisition, durable message-queuing, publish-subscribe messaging, and the efficient…
I expand on these concepts in my ScalaDays presentation in Berlin and New York. I have been using the Akka Streams API for about a year now and I have been extremely impressed with it. It is a framework for efficiently describing and executing streaming processes, while at the same…
I have worked on infrastructural software my entire career—mainly streaming-data systems for industrial applications. Infrastructural software is most often foundational, supporting other services and applications, rather than being the product itself. This can make it difficult to communicate the current state of the software, as well as its…
