Software Engineering Radio - The Podcast for Professional Software Developers

On Freund, founder of Wilco and former VP of Engineering at WeWork, speaks with SE Radio’s Brijesh Ammanath about “upskilling” – going deeper or increasing the breadth of your skills. On has years of experience in helping developers master the skills needed to advance in their careers. This episode explores the importance of upskilling in a constantly evolving tech landscape. They focus particularly on how and why senior and expert developers should keep learning, upskilling, and reskilling throughout their careers. Freund offers suggestions on how to face some common challenges, especially for remote or distributed workers, and how and why engineering managers can help enable upskilling for their teams.

Adam Tornhill, founder and CTO of CodeScene, joins host Giovanni Asproni to speak about behavioral code analysis. Behavioral code analysis is a set of practical techniques aimed at identifying patterns in how a development organization interacts with the codebase they're building. It can be used to prioritize technical debt to maximize return on investment; to identify communication and team-coordination bottlenecks in code; to drive refactorings guided by data from how the system evolves; and to detect code quality problems before they become maintenance issues. The episode starts with a broad description of the techniques, providing some examples from real projects, and ends with suggestions on how to get started with applying them. During the conversation, Adam and Giovanni touch on a set of related topics, including the applicability of the techniques to legacy, green-, and brown-field projects; ethical and privacy implications; and the importance of context when judging code quality.

Luca Casonato joins SE Radio's Jeremy Jung for a conversation about Deno and Deno Deploy.

From there they consider the benefits of creating an all-inclusive toolset like Rust and Go rather than relying on separate solutions, Deno's node compatibility layer, use cases for WebAssembly, benefits and implementation of Deno Deploy, reasons to deploy on the edge, and what's coming next.

Bernd Rücker, who has contributed to multiple open source workflow management projects, discusses orchestrating microservices with workflow management.  As distributed systems evolve into a family of microservices that must handle long-running stateful processes with time-dependent actions, events, multiple paths through the system, and complex rollbacks, the workflow management model provides a way to ensure clear modeling, correctness, and separation of concerns.   Rücker recommends a federated model in which each microservice is paired with its own workflow to handle retries and other policies and failure modes around that service.  Robert Blumen spoke with Rücker about microservice architecture, event-driven systems, long-running stateful processes versus synchronous request/response, event handling, time-outs, and handling exceptional conditions with compensating transactions. Rücker compares the choreography versus orchestration models for collaboration and discusses why orchestration provides a better separation of concerns.  The discussion delves into the implementation of workflow management systems including persistence, scaling, event handling, timers and scheduling, and similarities to CQRS.  The discussion wraps up with monitoring and visualization.

Prometheus is based off of the Borgmon monitoring tool, widely used at Google, where Brian previously worked. Jeff and Brian discuss the tradeoffs of choosing not to replicate our monitoring data. In some situations, the monitoring system will lose data because of this decision. Other topics that are discussed are distributed consensus tools, integrations with Prometheus, and the broader topic of monitoring itself.

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.
