Software Engineering Radio - The Podcast for Professional Software Developers

Andy Suderman, CTO of Fairwinds, joins host Robert Blumen to talk about standing up a kubernetes cluster. Their discussion covers build-your-own versus managed clusters provided by cloud services, and how to determine the number of kubernetes clusters an organization needs. Andy describes best practices for automating cluster provisioning, and offers recommendations about customizations and opinionation of cloud service providers, choice of container registry, and whether you should run complementary services such as CI and monitoring on the same cluster. The episode also examines the day 0/day 1/day 2 lifecycle, cluster auto-scaling at the cloud service level, integrating stateful services and other cloud services into your cluster, and kubernetes secrets and alternatives. Finally, they consider the container-network interface (CNI), ingress and load balancers, and provisioning external DNS and TLS certificates for cluster services.

Zac Hatfield-Dodds, the Assurance Team Lead at Anthropic, speaks with host Gregory M. Kapfhammer about property-based testing techniques and how to use them in an open-source tool called Hypothesis. They discuss how to define properties for a Python function and implement a test case in Hypothesis. They also explore some of the advanced features in Hypothesis that can automatically generate a test case and perform fuzzing campaigns.

José Valim, creator of the Elixir programming language, Chief Adoption Officer at Dashbit, and author of three programming books, speaks with SE Radio host Gavin Henry about what Elixir is today, what Livebook is, the five spearheads of the new machine learning ecosystem for Elixir, and how they all fit together. Valim describes why he created Elixir, what "the beam" is, and how he pitches it to new users. This episode examines things you can do with Livebook and how it is well-aligned with machine learning, as well as why immutability is important and how it works. They take a detailed look at a range of topics, including tensors with Nx, traditional machine learning with Scholar, data munging with Explorer, deep learning and neural networks with Axon, Bumblebee and Huggingface, and model creation basics.

M. Scott Ford, the CTO of Corgibytes and host of the Legacy Code Rocks podcast, discusses managing dependency freshness. SE Radio's Sam Taggart speaks with him about why dependency freshness is important to ensure that your code has all the latest bug fixes, how exactly to measure dependency freshness, and some of the insights that teams can gain from monitoring freshness over time.

Nikhil Shetty, an expert in networking and distributed systems, speaks with SE radio's Kanchan Shringi about virtual private cloud (VPC) and related technologies. They explore how VPC relates to public cloud, private cloud, and virtual private networks (VPNs). The discussion delves into why VPC is fundamental to building on the cloud, as well as configuring a VPC, subnets, and the address space that can be assigned to the VPC. During this episode they look into route tables, network address translation, as well as security groups, network access control lists, and DNS. Finally, Nikhil helps compare VPC offerings from Amazon Web Services (AWS) and Oracle Cloud Infrastructure (OCI).

Adam Frank, SVP of Product and Marketing at Armory.io, speaks with SE Radio's Kanchan Shringi about continuous integration, continuous delivery, and continuous deployment – and how they differ. Frank suggests that organizations begin by identifying how the CI/CD process aligns best with their unique goals, noting that such goals might be different for B2C versus B2B SAAS (software as a service). They also discuss how the process can differ for monoliths compared to microservices-based products. Finally, they talk about continuous deployment as a service and some unique aspects of Armory's approach.

Charles Weir—developer, security researcher, and Research Fellow at Security Lancaster—joins host Giovanni Asproni to discuss an approach that development teams can use to create secure systems without wasting effort on unnecessary security work. The episode starts with a broad description of the approach, which is based on Weir's research and on a free Developer Security Essentials workshop he created. Charles presents some examples from real-world projects, his view on AI's impact on security, and information about the workshop and where to find the materials. During the conversation, they consider several related topics including the concept of "good enough" security; security as a product decision; risk assessment, classification, and prioritization; and how to approach security in startups, greenfield, and legacy systems.

Lukas Fittl of pganalyze discusses the performance of Postgres, one of the world's most popular database systems. SE Radio host Philip Winston speaks with Fittl about database indexing, queries, maintenance, scaling, and stored procedures. They also discuss some features of pganalyze, such as the index and vacuum advisors.

Dr. Daniel Zingaro and Dr. Leo Porter, co-authors of the book Learn AI-Assisted Python Programming, speak with host Jeremy Jung about teaching programming with the aid of large language models (LLMs). They discuss writing a book to use in Leo's introductory CS class and explore how GitHub Copilot de-emphasizes syntax errors, reduces the need to memorize APIs, and why they want students to write manual test cases. They also discuss possible ethical concerns of relying on commercial tools, their impact on coursework, and why they aren't worried about students cheating with LLMs.

Zach Lloyd, CEO of Warp.dev, discusses how to implement and effectively use command-line terminals. Host Gregory Kapfhammer speaks with Lloyd about how command-line terminals work and how the Warp terminal uses the GPU and AI to enhance a software developer's productivity. They also discuss the trade-offs associated with using the Rust programming language to implement a command-line terminal. Brought to you by IEEE Computer Society and IEEE Software magazine.
