Software Engineering Radio - the podcast for professional software developers

Dave Cross, owner of Magnum Solutions and author of GitHub Actions Essentials (Clapham Technical Press), speaks with SE Radio host Gavin Henry about GitHub actions, the value they provide, and the best practices for using them in your projects. Cross describes the vast range of things that developers can do with GitHub Actions, including some use cases you might never have thought about. They start with some general discussion of CI/CD and then consider the three main types of events that drive GitHub actions before digging in to details about fine-grained action events, Action Marketplace, contexts, yaml, docker base images, self-hosted runners, and more. They further explore identity management, permissions, dependency management, saving money, and how to keep your secrets secret.

Ashley Peacock, author of the book Creating Software with Modern Diagramming Techniques, speaks with SE Radio host Akshay Manchale about diagrams in software engineering. They discuss the power of diagramming and some reasons we don’t fully use it as often as we should. Ashley contrasts historical use of UML diagrams versus modern diagrams, which don't have hard rules about representations. The episode examines different types of diagrams through an example application and how it could be built with modern tools such as Streamy to simplify the building, versioning, and maintenance of diagrams.

Luca Galante, head of product at Humanitec, joins host Jeff Doolittle for a conversation about platform engineering. They begin by defining platform engineering and its relationship to, and distinction from, DevOps. Tracing platform engineering's history, Luca describes how internal developer platforms are fundamental, and then explores the goals of addressing complexity and reducing the cognitive load on developers by creating golden paths.

Paul Hammant, independent consultant, joins host Giovanni Asproni to speak about trunk-based development—a version control management practice in which developers merge small, frequent updates to a core “trunk” or main branch. The episode explores the technique in some detail, including its pros and cons and some examples from real projects, and offers suggestions on how to get started. The conversation touches on a set of related topics, including code reviews, feature flags, continuous integration, and testing.

In this episode, David Cramer, co-founder and CTO of Sentry, joins host Jeremy Jung for a conversation about error tracking. The discussion starts with treating performance problems as errors, why you might not need logs, and how most applications share the same problems. From there they consider other topics including capturing information by hooking into runtimes and frameworks, issues with the quality of Open Telemetry data, how front-end applications are constantly changing and why that makes them hard to instrument. Finally, they discuss how Sentry's architecture has evolved, and why they switched from a permissive license to the Business Source License.

Bastian Gruber, author of the book Rust Web Development, speaks with host Philip Winston about creating server-based web applications with Rust. They explore Rust language features, tooling, and web frameworks such as Warp and Tokio. From there, they examine the steps to build a simple web server and a RESTful API, as well as modules, logging and tracing, and other aspects of web development with Rust.

Dan DeMers of Cinchy.com joins host Jeff Doolittle for a conversation about data collaboration and dataware. Dataware platforms leverage an operational data fabric to liberate data from apps and other silos and connect it together in real-time data networks. They explore a range of key topics, including zero-copy integration, encapsulation and information hiding, handling changes to data models over time, and latency and access issues. The discussion also explores dataware management and security concerns, as well as the concept of 'data plasticity' as an analogy to neuroplasticity, which is where the nervous system can respond to stimuli such as injuries by reorganizing its structure, functions, or connections.

Sugu Sougoumarane discusses how to face the challenges of horizontally scaling MySQL databases through the Vitess distribution engine and Planetscale, a service built on top of Vitess. The journey began with the growing pains of scale at YouTube around the time of Google’s acquisition of the video service. This episode explores ideas about topology management, sharding, Paxos, connection pooling, and how Vitess handles large transactions while abstracting complexity from the application layer.

Ross John Anderson, Professor of Security Engineering at University of Cambridge, discusses software obsolescence with host Priyanka Raghavan. They examine risks associated with software going obsolete and consider several examples of software obsolescence, including how it can affect cars. Prof. Anderson discusses policy and research in the area of obsolescence and suggests some ways to mitigate the risks, with special emphasis on software bills of materials. He describes future directions, including software policy and laws in the EU, and offers advice for software maintainers to hedge against risks of obsolescence.

Michael Fazio, Engineering Manager (Android) at Albert and author of Kotlin and Android Development featuring Jetpack from the Pragmatic Programmers, speaks with SE Radio's Gavin Henry about how the Android ecosystem looks today, and why it's an excellent time to write native Android apps. They explore a wide range of topics about modern Android development, including when to go native, how to keep a lot of decisions in your back-end API, Kotlin co-routines, Jetpack and Jetpack Compose, the MVVM design pattern, and threads, as well as activities, fragments, Dagger, room, navigation, Flutter, and improvements in simulators. They also examine details such as IDEs, API selection, how to choose a list of support devices, Java vs Kotlin, handset manufacturers, XML layouts, and why Jetpack is a safe bet for all your future Android development.
