Will McGugan, the CEO and founder of Textualize, speaks with host Gregory M. Kapfhammer about how to use packages such as Rich and Textual to build text-based user interfaces (TUIs) and command-line interfaces (CLIs) in Python. Along with discussing the design idioms that enable developers to create TUIs in Python, they consider practical strategies for efficiently rendering the components of a TUI. They also explore the subtle idiosyncrasies of implementing performant TUI frameworks like Textual and Rich and introduce the steps that developers would take to create their own CLI or TUI.

In this episode, SE Radio host Sriram Panyam explores HTMX with its creator, Carson Gross, who is also creator of Hyperscript, the mind behind the Grug Brained Developer, a professor of software engineering at Montana State University, and co-author of Hypermedia Systems.
HTMX is a modern JavaScript library that allows developers to access AJAX, WebSockets, CSS Transitions, and Server-Sent Events directly in HTML using attributes. It represents a return to hypermedia-driven application architecture while supporting modern user experiences. The episode starts with a look at the current complexity in web development and how HTMX offers an alternative approach. Carson explains the core philosophy of "HTML as the interface" and how hypermedia principles influenced HTMX's design. From there, they dive into HTMX's technical concepts, including its attribute system, server-side integration, event handling, and state management approach.
Carson shares some real-world implementation strategies, including migration paths from JavaScript frameworks, architectural patterns, and performance considerations -- as well as a few scenarios in which HTMX might not be the best fit. Finally, they look at the growing HTMX ecosystem, community contributions, and future development roadmap. Throughout the episode, Carson provides concrete examples and case studies of HTMX in production environments.

They discuss prototyping and why Rust is excellent for prototyping, and Matthias recommends a workflow for it, including what parts of Rust to use, and what parts to avoid at this stage. He describes the key components that Rust provides to help us validate ideas via prototypes, as well as tips and tricks to reach for.
In addition, the conversation explores type inference, unwrap(), expect(), anyhow crate, bacon crate, cargo-script, Rust macros to use, generics, lifetimes, best practices, project layout styles, and how to design through types.

Malcolm Matalka, founder of Terrateam, joins host Giovanni Asproni to talk about the reasoning behind choosing a not-so-widespread language (OCaml) and (almost) totally avoiding frameworks for the development of Terrateam. While discussing the reasons for choosing this specific programming language and the advantages and disadvantages of using external frameworks, they also consider a range of related topics, including static vs. dynamic typing, the use of monorepos, and the advantages of choosing a single language that can be used both for web front ends and server back ends. The episode ends with lessons learned that can be applied to other contexts and projects.

Tyler also discusses the security implications of external services, including authentication and authorization. They examine metrics and monitoring, with recommendations on the key metrics to collect, as well as acceptable error rates for external services. From there they consider what can go wrong, how to respond to external service outages, and challenges related to testing external services.

Software architect and author Vlad Khononov joins host Jeff Doolittle for a discussion on balancing coupling in software design. They start by examining coupling and its relationship to complexity and modularity. Vlad explains the historical models for assessing coupling and introduces his updated approach, integration strength, which aims to simplify earlier frameworks and adapt them for modern practices.
The episode explores three dimensions of coupling:
integration strength (knowledge sharing), distance (proximity of components), and volatility (likelihood of change).Vlad illustrates how design decisions can lead systems toward complexity or modularity, and he emphasizes the importance of managing coupling to minimize cognitive load and cascading changes. The conversation wraps up with insights on applying these principles to real-world software projects and a reminder of coupling's critical role in software architecture.

Sunil Mallya, co-founder and CTO of Flip AI, discusses small language models with host Brijesh Ammanath. They begin by considering the technical distinctions between SLMs and large language models.
LLMs excel in generating complex outputs across various natural language processing tasks, leveraging extensive training datasets on with massive GPU clusters. However, this capability comes with high computational costs and concerns about efficiency, particularly in applications that are specific to a given enterprise. To address this, many enterprises are turning to SLMs, fine-tuned on domain-specific datasets. The lower computational requirements and memory usage make SLMs suitable for real-time applications. By focusing on specific domains, SLMs can achieve greater accuracy and relevance aligned with specialized terminologies.
The selection of SLMs depends on specific application requirements. Additional influencing factors include the availability of training data, implementation complexity, and adaptability to changing information, allowing organizations to align their choices with operational needs and constraints.

Brenden Matthews, a seasoned software engineer, entrepreneur, and author of the Idiomatic Rust and Code Like a Pro in Rust books (both from Manning), speaks with SE Radio host Gavin Henry about Idiomatic Rust. They start with a look at what "idiomatic" means, and then discuss Generics, Traits, common design patterns you'll see in well written Rust code, and anti-patterns to avoid. Matthews suggests some tools that can help you immediately write idiomatic Rust, as well as what building blocks can also help. This episode examines what Generics are and how they compare to other languages, as well as what Traits are, how macros help, what a Fluent Interface is, and why unwrap() is bad. They also discuss what code smells to look out for, Clone, Copy, and a really nice place to go read real-world Idiomatic Rust code.

Ivett Ördög speaks with host Sam Taggart about rewrite versus refactor -- a choice that many projects face as they grow. It's a topic that inspires a lot of dogmatic feelings. They discuss how companies and projects end up at this crossroads and consider some strategies to try to avoid it. Ivett challenges the myth that you should never rewrite but points to two key factors that need to be present for a successful large-scale rewrite or refactor. They end by talking about how to get management on board for such large-scale rewrite or refactor projects.

In this episode, Charles Humble speaks withhost Brijesh Ammanath about skills that can provide developers a grounding in systems thinking.
Charles is a 30-year veteran of the IT industry, including as a former software engineer, architect, and CTO, as well as former editor in chief of InfoQ and chief editor for Container Solutions. He has published “Professional Skills for Software Engineers” as a series of 14 O’Reilly shortcuts covering communication, critical thinking, documentation, and networking.
Underlying his work is the idea that as complexity increases in IT systems, the roles of architects and leaders move from linear thinking to something that might be more broadly defined as systems thinking -- looking at problems and systems as a whole rather than just the individual parts. This requires a skill set that isn’t generally taught or widely valued as an industry -- in part, because it's hard to test in whiteboard interviews. It requires a mixture of communication skills; interpersonal skills; critical thinking; the ability to synthesize large amounts of information.
