His jacket was emblazoned with the logo of a manufacturer of high-performing heat pumps, but when I mentioned that we were thinking of getting one, the tech shot down the idea.

All-electric options have come a long way since their inception, and there’s never been a better time to get on board.

If contractors in colder climates focus on educating their customers on what new higher-efficiency furnaces bring to the table, often times the furnaces will sell themselves.

Due to a lack of training, time constraints, and numerous other reasons, many HVAC contracting companies are not performing combustion testing, potentially compromising customers’ safety.

Changeable software has been a goal of several technique in software engineering. Probably the most important is Refactoring, changing the code without changing the behaviour (or at least without breaking the tests). In this episode Eberhard talks with Martin Lippert about this technique. The episode covers a history of refactoring, a definition of code smells and how to actually do refactorings in your everyday work. Also some advanced topics - like the ROI of Refactoring or Refactoring in dynamic languages - are covered.

In the first episode on Refactoring we talked about the basic ideas behind refactoring and some base principles why refactoring is a key part of software engineering. Now we move on to more complicated refactorings and discuss three major situations, their problems and possible solutions: advanced refactorings in large projects that can hardly be finished in a few minutes or hours and refactoring in larger teams. Also covered are the refactoring of published APIs and how merciless refactoring could be aligned with backward compatibility of published APIs, and refactorings that affect more than just code like for example database schemas.

In this episode we talk with Kent Beck about automated unit testing and JUnit.

Nathan Marz is the creator of Apache Storm, a real-time streaming application. Storm does for stream processing what Hadoop does for batch processing. The project began when Nathan was working on aggregating Twitter data using a queue-and-worker system he had designed. Many companies use Storm, including Spotify, Yelp, WebMD, and many others. Jeff and Nathan […]

Jeff Meyerson talks with Brian Brazil about monitoring with Prometheus, an open source tool for monitoring distributed applications. Brian is the founder of Robust Perception, a company offering Prometheus engineering and consulting. The high level goal of Prometheus is to allow developers to focus on services rather than individual instances of a given service. Prometheus is based off of the Borgmon monitoring tool, widely used at Google, where Brian previously worked. Jeff and Brian discuss the tradeoffs of choosing not to replicate our monitoring data. In some situations, the monitoring system will lose data because of this decision. Other topics that are discussed are distributed consensus tools, integrations with Prometheus, and the broader topic of monitoring itself.

J.R. Storment and Mike Fuller discuss cloud financial operations (FinOps) with host Akshay Manchale. They consider the importance of a financial operations strategy for cloud-based infrastructure. J.R. and Mike discuss the differences between operating your own data center and running in the cloud, as well as the problems that doing so creates in understanding and forecasting cloud spend. Mike details the Cloud FinOps lifecycle by first attributing organizational cloud spend through showbacks and chargebacks to individual teams and products. JR describes the two levers available for optimization once an organization understands where they're spending their cloud budget. They discuss complexities that arise from virtualized infrastructure and techniques to attribute cloud usage to the correct owners, and close with some recommendations for engineering leaders who are getting started on cloud FinOps strategy.

Adam Tornhill, founder and CTO of CodeScene, joins host Giovanni Asproni to speak about behavioral code analysis. Behavioral code analysis is a set of practical techniques aimed at identifying patterns in how a development organization interacts with the codebase they're building. It can be used to prioritize technical debt to maximize return on investment; to identify communication and team-coordination bottlenecks in code; to drive refactorings guided by data from how the system evolves; and to detect code quality problems before they become maintenance issues. The episode starts with a broad description of the techniques, providing some examples from real projects, and ends with suggestions on how to get started with applying them. During the conversation, Adam and Giovanni touch on a set of related topics, including the applicability of the techniques to legacy, green-, and brown-field projects; ethical and privacy implications; and the importance of context when judging code quality.

Casey Muratori caused some strong reactions with a blog post and an associated video in which he went through an example from the “Clean Code” book by Robert Martin to demonstrate the negative impact that clean code practices can have on performance. In this episode, he joins SE Radio’s Giovanni Asproni to talk about the potential trade-offs between performance and the qualities that make for maintainable code, these qualities being the main focus of Clean Code.

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.

Jonathan Schneider, the cofounder of Moderne and the creator of OpenRewrite, talks with SE Radio's Gregory Kapfhammer about automated software maintenance. In addition to exploring the design and implementation of OpenRewrite, Schneider explains how the tool can automatically support software maintenance tasks such as framework migration and security fixes for programs implemented in languages like Java. The episode also explores how OpenRewrite uses the lossless semantic tree to support automated refactoring though the use of recipes.
