A homeowner in Pickering, Ontario works with an experienced HVAC pro to improve comfort, efficiency, and energy savings with a high-efficiency hydronic forced-air furnace upgrade.

This episode is about compile-time metaprogramming, and specifically, about implementing DSLs via compile-time metaprogramming. Our guest, Laurence Tratt, illustrates the idea with his (research) programming language called Converge.

We started by talking about the importance of a custom syntax for DSL and took a brief look at the definition of DSLs by a chap called Paul Hudak. We then briefly covered the disctinction between internal and external DSLs.

More to the point of this episode, we discussed the concept of compile-time metaprogramming, and the language features necessary to achieve it: in converge, these concepts are called splice, quasi-quote and insertion. We then looked at how the Converge compiler works, and at the additional features that are required to implement DSLs based on the metaprogramming features mentioned above. Using an example, we then walked through how to implement a simple DSL.

Looking at some of the more technical details, we discussed the difference between the parse tree and the abstract syntax tree and at different kinds of parsers - specifically, the Earley parser used by Converge. In multi-stage languages (i.e. languages that execute programs and meta programs) error reporting is important, but non trivial. We discussed how this is done in Converge. We finally looked at how to integrate Converge's expression language into your DSL and how to package DSL definition for later use.

The last segment look at the process of implementing a DSL in converge and about some of the history and practical experience with Converge. Lessons learned from building Converge wrap up the episode.

In this episode, Michael and Markus talk about software components. We first looked at a couple of attempts at defining what a component is. We then provided our own definition that will be used in the rest of the episode. We then looked at the promises of component-based development: why are components useful? We then discussed some of the typical metadata components should specify to make them useful. We discussed to some extent typical variations in component models. The next topic was the separation of concerns between the component functionality and functionality provided by the component's execution environment (aka. container). We then compared components with other (more or less) related technologies such as OO and SOA. We concluded the episode with the notion of architecture as language, where you use a formal DSL to describe a system's architecture. Components are the basic building block for this approach.

Michael discusses with his guest Chuck Connell the differences between software engineering and computer science. What makes software engineering so unpredictable, with so few formal results? And how can we advance the field of software engineering without these results?

We talk with Martin Laforest about topics ranging from how quantum computing works, which different models of quantum computing are explored, current and future uses of the approach as well as the current state of the art.

Johannes Thönes talks to Patrick Kua about the role of a technical lead and how to become one. The show starts with introducing the concept of a lead and contrasts the lead role with other roles, such as technical manager, architect and senior developer.  The discussion continues to the responsibilities of a tech lead (supporting engineering practices, managing, resolving conflict, and growing people). The discussion continues on to talk about the challenges of becoming a tech lead and how to overcome them and closes with the question: “how can you tell if you are succeeding as a tech lead”?

Edaena Salinas talks with Maria Gorlatova about Edge Computing. Maria Gorlatova is an Associate Research Scholar at Princeton University Department of Electrical Engineering. The discussion covers: IoT, edge computing, the architecture of edge computing, running a machine learning model on the edge, and the benefits of edge computing.

Arun Gupta, Vice President and General Manager of Open Ecosystem Initiatives at Intel Corporation, discusses open-source strategy and community with SE Radio host Kanchan Shringi. They explore the business case and business model for why and how big tech participates in the open-source ecosystem. Arun describes ways to foster a culture of engagement with open source within companies such as Intel, Amazon, and Apple. They then consider how the principles can be applied to closed-source software within a company. Finally, they discuss some of the benefits that Intel has gained from more than 20 years of open source contributions and look at the company’s plan for the year ahead.

Josh Doody, author of Mastering Business Email, speaks with host Brijesh Ammanath about how software engineers can master business communication. They begin with an exploration of various communication modes, including Slack, virtual meetings, emails, and presentations. Josh shares several strategies to improve communication skills and cross-cultural communication, but if there's one key take away from this episode, it might be: “use positive language for any medium of communication; be kind and use positive words.” Brought to you by IEEE Software magazine and IEEE Computer Society.
