Charles Nutter from the JRuby project talks to Charles Anderson about JRuby and the Java Virtual Machine (JVM) as a platform for implementing programming languages. They begin by discussing the Java platform beyond just the Java language. As a case study in implementing a language other than Java on the JVM, they discuss JRuby - what it is and how it’s implemented on the JVM. They discuss recent additions to the Java platform like the invoke-dynamic byte code and lambdas in Java 8. The conversation concludes by discussing the future of the Java language, platform, and virtual machine.

Johannes Thönes talks to Patrick Kua about the role of a technical lead and how to become one. The show starts with introducing the concept of a lead and contrasts the lead role with other roles, such as technical manager, architect and senior developer.  The discussion continues to the responsibilities of a tech lead (supporting engineering practices, managing, resolving conflict, and growing people). The discussion continues on to talk about the challenges of becoming a tech lead and how to overcome them and closes with the question: “how can you tell if you are succeeding as a tech lead”?

Charles Anderson talks with James Phillips about service discovery and Consul, an open-source service discovery tool. The discussion begins by defining what service discovery is, what data is stored in a service discovery tool, and some scenarios in which it’s used. Then they dive into some details about the components of a service discovery tool and how reliability is achieved as a distributed system. Finally, James discusses Consul, the functions it provides, and how to integrate it with existing applications, even if they use configuration files instead of a service discovery tool.

David Heinemeier Hansson, creator of the Ruby on Rails framework and a partner at the software development company Basecamp, talks to Stefan Tilkov about the state of Ruby on Rails and its suitability for long-term development. He addresses some of its common criticisms, such as perceived usefulness for only simple problems, claimed lack of scalability, and increasing complexity. David also talks about the downsides of building JavaScript-centric, “sophisticated” web UIs, and why he prefers well-structured, “majestic” monoliths to microservices.


Jeff Meyerson talks to Haoyuan Li about Alluxio, a memory-centric distributed storage system. The cost of memory and disk capacity are both decreasing every year–but only the throughput of memory is increasing exponentially. This trend is driving opportunity in the space of big data processing. Alluxio is an open source, memory-centric, distributed, and reliable storage system enabling data sharing across clusters at memory speed. Alluxio was formerly known as Tachyon. Haoyuan is the creator of Alluxio. Haoyuan was a member of the Berkeley AMPLab, which is the same research facility from which Apache Mesos and Apache Spark were born. In this episode, we discuss Alluxio, Spark, Hadoop, and the evolution of the data center software architecture.

Robert Blumen talks with Cody Voellinger, the founder of a recruiting firm that specializes in filling software engineer roles for San Francisco-area startups, about how jobs are created and how companies and engineers get matched up. Their discussion covers the entire job search process, from job descriptions to salary negotiations. They look at the job market from both sides: how companies define what they want, find the right people, and evaluate candidates, and how job seekers can position themselves for the role they want. Other topics include culture fit versus skill and resumes in an age of social networking. They conclude with a look at the mistakes that job seekers, recruiters, and companies should avoid.

Michael Nygard of “Release It!” fame talks with Stefan Tilkov about his experience using the Clojure programming language. Topics include the tool chain and development process, the Clojure learning curve, and on-boarding new developers. Michael explains the similarities and differences compared to typical OO languages when implementing domain logic, and uses both game development and typical web development projects as examples. Finally, the two discuss how well Clojure can be used in the face of long-running projects, and some typical obstacles and strategies for introducing it to real-world scenarios.
