    AI-augmented software development

    Luca and Jeff dive into how AI tools can supercharge embedded development workflows. Luca shares his extensive hands-on experience, while Jeff brings a fresh perspective as someone just starting to incorporate these tools. They explore how AI can help with coding, testing, and debugging - while emphasizing that good software engineering judgment remains crucial. The conversation is particularly timely since AI tools are evolving rapidly, unlike their usually more "evergreen" podcast topics. A key insight they discuss is that while AI tools offer amazing productivity boosts (much like IDEs did), they're not replacing experienced developers anytime soon. However, they raise interesting questions about the future job market for junior developers. Their take? Modern developers should absolutely embrace AI tools, but use them thoughtfully - especially when learning. Key Timestamps and Topics: 00:00:00 - Welcome and episode overview 00:00:43 - Why this topic won't age well (but that's okay!) 00:02:20 - Breaking down different AI coding tools 00:08:00 - Deep dive into aider and workflow integration 00:20:02 - Using AI for testing and test-driven development 00:27:00 - AI-assisted architecture work and its limitations 00:30:40 - How AI helps explore unfamiliar codebases 00:33:30 - Debugging with AI - pros and cons 00:38:50 - What this means for development jobs 00:43:59 - Using AI to learn new frameworks/languages 00:46:15 - Embedded Online Conference preview You can find Jeff at https://jeffgable.com.You can find Luca at https://luca.engineer.

    BONUS: Listener Question on Repository Organization

    ## Key Topics   * [00:30] Introduction to the listener's question about repository granularity in embedded development * [01:15] The listener's approach: separate repositories for different work products in safety-critical industries * [03:20] Luca's initial reaction and concerns about over-complication * [05:45] Discussion of monorepo approaches and configuration management * [08:10] The concept of micro-repositories and parallels to microservices * [11:30] Using feature flags and CI pipelines instead of repository separation   ## Notable Quotes   > "You're splitting something which ought to be joined together into different repositories and hiding whatever is happening within the repositories from the different users, from the different developers." — Luca Ingianni   > "The risk of course is that you will not spot divergence early enough because people just don't merge because it's a chore and because things might break, and of course that is the point - the earlier you notice that something breaks, the easier it will be to fix it." — Luca Ingianni   > "I'm willing to guarantee that you're going to get the architecture wrong at least on the first try. You think you're being really smart and you cut it up into a bunch of microservices or micro-repositories, and you're just going to get the boundaries wrong." — Luca Ingianni   > "I would opt for fewer repositories and rather do configuration management within the repositories as opposed to between repositories. Use feature flags, use tagging, use whatever you want to insulate changes that might be breaking from the rest of the code base." — Luca Ingianni   ## Resources Mentioned   * John Taylor's Embedded Project Cookbook - A resource mentioned by the listener that discusses sequential events in embedded projects * Trunk-Based Development - Development methodology discussed throughout the episode * Minimum CD Podcast - Previous podcast episode referenced by the listener     You can find Jeff at https://jeffgable.com.You can find Luca at https://luca.engineer.

    MinimumCD

    The episode discusses the concept of Minimum Viable Continuous Delivery (Minimum CD), which represents a counter-movement to heavyweight frameworks like SAFe. The hosts explore how Minimum CD provides a set of essential practices for successfully building software-based products without unnecessary complexity. The approach focuses on core principles rather than rigid frameworks, making it particularly relevant for embedded systems development. The discussion covers the fundamental requirements for continuous delivery, including automated testing, pipeline-driven deployments, and trunk-based development. The hosts emphasize that while these practices may seem challenging for embedded systems, they become increasingly important as devices become more sophisticated and connected. A key theme throughout the episode is the importance of building trust in the development process through automation, consistent practices, and cultural commitment. The hosts stress that while some practices may seem difficult to implement in embedded systems, the more challenging they are, the more valuable they become when successfully implemented.

    Key Topics[02:30] Definition of BDD as an additional layer of discipline on top of TDD[03:15] Common pitfalls of TDD, including testing to implementation and brittle tests[08:30] The structure of BDD tests using Given-When-Then format[12:00] Applying BDD at different levels, from unit tests to system tests[15:45] Using test doubles and spies for hardware interactions in embedded systems[22:30] Testing state machines with BDD[27:00] Off-target testing and hardware abstraction layers[33:00] Why BDD isn't more widely used in embedded systems[36:30] Using code coverage as a signal rather than a goal metric[39:00] Overcoming the learning curve and maintaining discipline in BDDNotable Quotes"BDD is an additional layer of discipline on top of TDD. Dan North's goal was to get straight to the good stuff of TDD without getting into the pitfalls." — Steve "The key thing that BDD does by saying we're going to focus on behavior is you look at the API that you've written and you say, what can I do through the public API to affect this, to check the results and so forth?" — Steve "By having abstraction layers, you create your thin layer that's substitutable with either the real code on target, or with a test double off target." — Steve "Code coverage as a goal metric is not a good thing. Rather than using code coverage as just this almost dimensionless metric, use it as a signal to guide you." — Steve "By adhering very strictly to the simple rules of how to do BDD, by forcing yourself to the discipline of that strict adherence, it keeps you on track." — Steve Resources MentionedJames Grenning's bookSteve's blog postEmbedded Online TalkIan Cooper's video You can find Jeff at https://jeffgable.com.You can find Luca at https://luca.engineer.

    John Taylor on the Embedded Systems Cookbook

    John Taylor returns to the podcast to discuss his new book "The Embedded Project Cookbook", co-authored with Wayne Taylor. The book serves as a practical guide for embedded systems development, providing recipes and techniques that John has refined over his 30+ year career. Unlike his previous book "Patterns in the Machine" which focused on software engineering best practices, this new book takes a more hands-on approach to project mechanics - from requirements gathering through release. The book provides opinionated guidance on setting up project infrastructure, managing requirements, software architecture, and release processes. While organized in a waterfall-like structure for clarity, it emphasizes the need for agility in embedded development. A key theme is establishing good practices early to make releases boring and predictable rather than chaotic. The content is valuable for different roles - from junior developers seeking context about the full development lifecycle, to technical leads implementing processes, to managers needing justification for development infrastructure investments. While the book presents John's specific approaches, he emphasizes that teams can adapt the recipes to their needs as long as they deliberately address the underlying challenges. Key Topics Discussed (Timestamps): 00:00:00 - Introduction and background on John Taylor 00:02:00 - Comparison to previous book "Patterns in the Machine" 00:06:00 - Target audience and use cases 00:15:00 - Software Development Plans and their value 00:20:00 - Foundation setup before coding begins 00:27:00 - Managing project variants and configurations 00:30:00 - Communication and collaboration practices 00:35:00 - Release management and ongoing development 00:40:00 - Iterative development cycles 00:43:00 - Book availability and contact information Links: Embedded Systems Cookbook: https://link.springer.com/book/10.1007/979-8-8688-0327-7 Patterns in the machine (the previous book): https://link.springer.com/book/10.1007/978-1-4842-6440-9 John's LinkedIn: https://www.linkedin.com/in/john-tanner-taylor/ You can find Jeff at https://jeffgable.com.You can find Luca at https://luca.engineer.

    Trunk-based development

    In this episode, Jeff and Luca discuss trunk-based development, a software development practice where developers merge their work into the main branch (trunk) frequently - at least daily. They explain how this approach differs from traditional branching models like GitFlow, and address common objections and concerns. The hosts emphasize that while trunk-based development may seem risky, it actually reduces risk by exposing integration problems early and forcing teams to implement good engineering practices like automated testing and feature flags. The discussion highlights how trunk-based development acts as a "forcing function" that encourages better development practices, smaller changes, and more frequent collaboration between team members. They explain that while this approach originated in web development, it's equally applicable to embedded systems. The hosts cite research from the book "Accelerate" showing that trunk-based development is a predictor of high-performing software teams. The episode concludes by emphasizing that most objections to trunk-based development actually point to underlying process issues that need to be addressed, and that the benefits of early integration and feedback outweigh the perceived downsides.
