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.

In this episode, David Cramer, co-founder and CTO of Sentry, joins host Jeremy Jung for a conversation about error tracking.

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.

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 conversation touches on a set of related topics, including code reviews, feature flags, continuous integration, and testing.

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.

Vladyslav Ukis, author of the book Establishing SRE Foundations: A Step-by-Step Guide to Introducing Site Reliability Engineering in Software Delivery Organizations, discusses how to roll out SRE in an enterprise.

They examine how firms can establish foundations for rolling out SRE, as well as how to overcome challenges they might face in adopting. Vlad also recommends steps that organizations can take to sustain and advance their SRE transformation beyond the foundations.

Stanisław Barzowski of XTX Markets and a committer on the jsonnet project joins SE Radio's Robert Blumen for a conversation about the jsonnet programming language. A superset of JSON, jsonnet adds programming language capabilities, particularly to address the need to handle large but mostly repetitive JSON configurations. They discuss the project’s history, use cases for Grafana and Kubernetes config, and interoperability with YAML. They examine jsonnet details, including the command line, constrained capabilities of the language, and objects and inheritance, and then consider the toolchain: compiler, formatter, and linter, as well as test frameworks and testing, package management, and the language’s performance. Barzowski describes four implementations -- go, C++, Rust, and Scala -- as well as popular libraries and the standard library.

Gregory Kapfhammer, associate professor at Allegheny College, discusses the common problem of ‘flaky tests’ with SE Radio’s Nikhil Krishna. Flaky tests are test cases that unreliably pass or fail even when no changes are made to the source code under test or to the test suite itself, which means that developers can’t tell whether the failures indicate bugs that needs to be resolved.  Flaky tests can hinder continuous integration and continuous development by undermining trust in the CI/CD environment. This episode examines sources of flaky tests, including physical factors such as CPU or memory changes, as well as program-related factors such as performance issues. Gregory also describes some common areas that are prone to flaky tests and ways to detect them. They discuss tooling to detect and automatically mark flaky tests, as well as how to tackle these issues to make tests more reliable and even ways to write code so that it's less susceptible to flaky tests.

Jens Neuse, founder of Wundergraph, joins SE Radio host Jeff Doolittle for a conversation about back ends for front ends, or BFF. Jens begins by explaining how a heavy integration burden is often placed on front-end development teams. When multiple APIs must be integrated, it can be challenging for client development in web, mobile, and desktop environments. Explaining how APIs should be treated as dependencies, just like packages, the episode explores BFF patterns and use cases, as well as the future potential emergence of a “git for APIs” standard. This episode is sponsored by ClickSend. 

In this episode, Ori Mankali, senior VP of engineering at cloud security startup Akeyless, speaks with SE Radio’s Nikhil Krishna about secrets management and the innovative use of distributed fragment cryptography (DFC). In the context of enterprise IT, 'secrets’ are crucial for authentication in providing access to internal applications and services. Ori describes the unique challenges of managing these sensitive data, particularly given the complexities of doing so on a large scale in substantial organizations. They discuss the necessity for a secure system for managing secrets, highlighting key features such as access policies, audit capabilities, and visualization tools. Ori introduces the concept of distributed fragment cryptography, which boosts security by ensuring that the entire secret is never known to any single entity. The episode explores encryption and decryption and the importance of key rotation, as they consider the challenges and potential solutions in secrets management.
