How's your architecture game? Carl and Richard talk to Thomas Betts about being a better architect. Thomas focuses on the key aspect - communication! An effective architect can talk to all the stakeholders in the language of the stakeholder, whether that's speaking business with business stakeholders, coding with developers, and understanding the needs of the security and operations folks. All those aspects (and more) go into an effective architecture and then come the changes as the implementation challenges happen. The conversation also digs into the importance of documentation to know why decisions were made and how to change them as you respond to changing needs and landscapes.

Large Language Models like GPT-4 are all the rage - how do we use them well? Carl and Richard talk to Amber McKenzie about the challenges and concerns around LLMs, especially regarding the data involved. Amber talks about the risks of creating products around LLMs while the technology is so young and constantly evolving, especially with how the general public reacts to conversational AI. Education is key, and constantly fact-checking - good advice for a lot of technology, but LLMs are making fact checking even more important!

Microservices or Monoliths? Carl and Richard talk to Layla Porter about choosing a middle ground between microservices and monoliths, with modular monoliths. Layla talks about the pushback from the community around microservices and the insistence that there is "one right way." Monoliths have their advantages until they are a problem - but that doesn't mean that re-architecting everything is the right way to go. Chipping off parts of the monolith into satellite modules strikes a balance of flexibility and scalability - and opens the door to accessing the power of bus architectures when needed!

Databases continue to evolve! Carl and Richard talk to Ted Neward about multi-model data stores - which, these days, are most databases! Ted talks about how SQL and NoSQL are not that different - it's only a query engine. But how do you store your data? Today multi-model databases store data with multiple storage engines, and so can store your data in the most appropriate form. There are lots of choices, and it's worth digging deeper into your existing data stores, as well as the new ones available!

What can we do to make testing easier? Carl and Richard talk to Dennis Doomen about Fluent Assertions, an open-source set of extension methods to help write better tests.

The conversation also digs into how these types of open-source projects don't make money, even though they help many people. Could we fix that?

How do you scale a monolith? Carl and Richard talk to Derek Comartin about his blog posts and YouTube series around scaling a monolith. Derek talks about the tendency for folks to want to split a monolith into microservices without assessing if it will make a difference. There is no one right way! The conversation digs into different approaches to scaling - up, out, using caching, queuing, and more! There are many approaches to scaling your applications, and yes, microservices are an option, but there are many others!

Can you quit your job and work full-time on your open-source project? Carl and Richard talk to Shaun Walker about his recent move to focus on Oqtane, the open-source application framework and CMS he has been developing for the past few years. Shaun talks about recognizing when an open-source project has matured to the point that it is being held back by not also providing a commercial license. For some folks, a commercial license is not an option - they need it to be able to use the software within the company. Then comes the tricky part: Setting up a business, and balancing the needs of the open-source community with the commercial customers. It isn't easy, but it can be done!

How do you get your app running in Azure? Carl and Richard talk to Savannah Ostrowski about Azure Developer CLI (azd), an open-source tool to help developers using .NET, Javascript/Typescript, Python, Java, and more to get deployed into Azure. Savannah talks about staying high-level with azd commands, keeping the complexity of deployment pipelines in tools you already know how to use, like Bicep and Terraform. The conversation digs into the templating system to help assemble all the platforms and elements of an Azure deployment, depending on your application. There are a ton of options - check it out!

How can OpenAI help you program faster? Carl and Richard talk to Mark Miller about his experiments with OpenAI and CodeRush. Mark talks about the power of building agents to analyze code to write comments and tests - in parallel so that multiple agents can run simultaneously. Then the conversation turns to the potential of a voice interface as an effective way to work with Visual Studio - you were talking anyway!

What can OpenTelemetry do for you? While at Techorama in Belgium, Carl and Richard talked to Laïla Bougriâ about her experiences with the open-source library that can help give you more insight into the behavior of your applications. Laïla talks about being able to instrument your applications from top-to-bottom, regardless of platforms or development stacks. The conversation digs into the differences between logging, tracing, and telemetry - and how each aspect adds value to understand what your applications are doing, and how you can make them better!

When it comes to machine learning, there is no free lunch! While at Techorama in Antwerp, Carl and Richard talked to Dr. Jodie Burchell about her experiences working with machine learning models, including the large language models that drive tools like ChatGPT. Jodie starts with a great explanation of how these machine learning models are built - and there is a lot to it! This leads to a conversation about the limitations of those models and how they could be improved further. There's a lot of hype around LLMs right now - it will pass eventually, but in the meantime, be thoughtful of how you use these experimental technologies!

The power of .NET means PHP can run in the browser efficiently! Carl and Richard talk to Jakub Míšek about PeachPie using WASM. Jakub talks about how easy it was to deploy PeachPie, the .NET implementation of PHP, into WebAssembly, much like Blazor works. Then the tricky bit starts - PHP is a server-side technology, so many of the constructs are based on trips to a server. That doesn't mean there aren't solutions, but they need some thinking through. The question is, do we want to run WordPress in a browser?

What's an immutable architecture, and why do you want one? Carl and Richard talk to Michael Perry about his book The Art of Immutable Architecture and the power of historical models. Michael talks about different designs for immutability, the ability to always look back through data, to avoid conflict between resources, and the advantages of eventual consistency. As Michael says, you already use immutable architecture - look at Git and how you only add new files to the system, always able to get back to a previous state! The conversation dives into implementing architecture in a way that helps to show where immutability makes sense.

How do you do more with Entity Framework? Carl and Richard talk to Erik Ejlskov Jensen about his work contributing to Entity Framework and creating tools to make Entity Framework easier to use. Erik talks about how EF has continued to evolve, including some significant performance optimizations. The conversation also explores code-first vs. database-first - although Erik falls firmly into the schema-first mindset. There's more coming for Entity Framework; it's worth your time to get the most from it!

How do we support open-source projects? Carl and Richard talk to Joseph Finney about his ongoing efforts to build various projects in his spare time while still working a regular day job. Joe talks about the options to contribute to open-source, including submitting issues to help improve the project, code contributions where you add to the body of work, and financial options - contributing money directly to the creator. The conversation explores some of the existing tooling and more opportunities that could be created to make it easier for organizations to see their dependence on open-source libraries in a path that would make it easier to garner support for creators. The open-source world continues to evolve, and with some effort, we can make it more sustainable and valuable for everyone.

Web Testing Evolved! Carl and Richard talk to Ely Lucas about the latest version of the Cypress Testing Framework. Ely talks about three significant versions shipping in 2022 - starting with version 10, a complete UI overhaul. Following the semantic versioning standards, versions 11 and 12 had some breaking changes, primarily around component testing and other great new features. Today Cypress is effective at end-to-end testing, component testing, and with an open source plugin, API testing. The product is free and open-source, with a paid version offering enterprise-class cloud services for scaling testing up. Check it out!

How do you know the code you write is being used in production? Carl and Richard talk to Roni Dover about his work with Digma to help bring code utilization into your development tooling. Roni talks about the challenges of getting and using production telemetry - often, it never reaches developers. But with OpenTelemetry, there's a lot of data out there; the challenge is to present it helpfully - and that's what Digma is all about. It's still in beta, but sign up if you want to get involved!

Microsoft is making several Copilot products - should you? Carl and Richard talk to Phil Haack about the latest version of ab.bot, his customer success startup. Now Phil is calling ab.bot a Copilot for Customer Success since he incorporated OpenAI ChatGPT into it. The conversation tries to steer clear of the hysteria around modern large language models (although it is hard!) and more into the practical applications - using large language models to summarize long customer support conversations and find related conversations to current ones - perhaps identifying new high-priority features! The wave of large language models is in its early days, and with the new APIS available, it may be time to make them part of your projects too!

What if you didn't have to choose between client-side and server-side Blazor? Carl and Richard talk to Javier Nelson and Steve Sanderson about Blazor United in its early stages of development, providing flexibility at the web component level for client- and server-side rendering. At the simplest level, Blazor United offers server-side rendering when a site is first hit so that you can load the larger client-side components over time. But deeper is the idea that some elements on your web page benefit from being client-side, and some from being server-side, and why should you have to choose only one?

How do you create a sustainable open-source ecosystem? Carl and Richard talk to Sarah Novotny about how the open-source community continues to evolve. Sarah talks about how the vast majority of software utilizes open-source code and should be contributing to those projects. Those contributions can be financial or development resources, whatever makes more sense for the organization. The conversation also explores the nature of those contributions when the project has smaller and larger audiences, is purely for developer consumption, or the greater public. Open-source software is diverse, so the support for open-source software also needs to be diverse!

MAUI is out! What's next? While at Swetugg in Stockholm, Carl and Richard chatted with David Ortinau and Maddy Montaquila about getting MAUI shipped and seeing how the world is using it! The conversation digs into what typical developers are doing with MAUI and other platforms in the plans for future MAUI. David and Maddy talk about how Blazor Hybrid is creating a lot of excitement for folks, balancing the reach of web development with the power of native development - it's a great time to be building cross-platform software!

How can the cloud help developer velocity? Carl and Richard talk to Bryan Foster about the complexities of modern software development - and how different cloud technologies can help move faster and not be afraid to break a few things along the way! Bryan talks about using Azure Deployment Environments to make it easy for developers to stand up resources for their apps - and just as quickly shut them down when done. This leads to a broader conversation around the governance of CI/CD pipelines and the role of the cloud, even to the point of using DevBox to have an entirely virtualized development environment!

Why write functional C#? Carl and Richard talk to Simon Painter about what happens when you apply functional programming approaches to your C# code. Simon discusses how some functional programming aspects are best served in a functional language like F#, but you can write C# in a more functional style. The conversation focuses on minimizing side effects - writing your code so that you can see what it does and how it would behave when changed. Functional code tends to be more testable as well!

How do you secure your existing applications from the security exploits out there today? Carl and Richard talk to Joylynn Kirui about the challenges developers face in making secure applications. Joylynn talks about understanding the threat landscape and staying up to date on the CVEs that can represent a zero-day vulnerability to your application. There are a ton of tools to help make you aware of the potential risks, check out all the links in the show notes. And check out Joylynn's webinar on shifting application security left at https://aka.ms/DevSecOpsDNR

Why should you have high-level design in your applications? Carl and Richard chat with Billy Hollis about the concepts around high-level design and how it can help make better software. Billy talks about how high-level design addresses more than UX concerns, expanding into architecture and business workflow to think more deeply about how we use software. And of course, Billy digs into various applications we all use (looking at you, Teams!) and talks about how high-level design could help deal with the challenges around those kinds of applications. Is it needed everywhere? No - but more is needed!

An MAUI version of Doom? Carl and Richard talk to Wesley Cabus and Nico Vermeir about their efforts to port the venerable game Doom to C# and .NET 6 with MAUI as the UI. Wesley did the base conversion of Doom over to .NET, while Nico focused on getting the UI working through MAUI. Converting code, graphics, music, and sound effects from the 1990s into modern solutions is challenging but fun! Primarily working on the PC, there's a concerted effort to get a version running on Android devices too - and they could use your help!

Ready for some space? Richard talks to Carl about all the incredible space-related stories in 2022. Starting with a record launch year - more flights to orbit than any year in history! Then the conversation digs into some cool missions around the solar system, including the Double Asteroid Redirection Test - we're learning how to protect our planet against asteroid impacts! Then on to space stations (there's more than one!) and, of course, the Moon - so many missions to the Moon! The biggest is Artemis, but there are plenty of others. And then there's the James Webb Space Telescope... what a fantastic year in space!

Jeremy Miller is back with more open-source goodness in the form of the Wolverine .NET Command and Message Bus. Jeremy talks about developing the Marten database and reaching a point with event sourcing that led to Wolverine - building the infrastructure to work with a variety of queuing solutions to act as an intermediary, a message bus, and a command bus, as needed. The conversation also digs into the current state of open-source with his projects, and the evolution toward more sustainable open-source development - there is more to come!

ChatGPT, BingAI, and Google Bard are the latest examples of large language model machine learning - are we at an inflection point in technology? Carl and Richard talk to Grant Barrett of A Way with Words about the power of these new technologies to solicit reactions from many folks, including many tech journalists. Grant talks about how language conveys a sense of intelligence even when there is none to be had and the problems created by those assumptions. It is still the early days for these chatbots - will they rapidly improve or fade into another AI winter?

Do you know what your web app is up to? Carl and Richard talk to Sam Basu and Rosen Vladimirov about the latest versions of Fiddler. The original Fiddler for Windows is a free tool, but the Progress team has written all new products in the Fiddler space that are cross-platform and designed to work with different groups of people. Fiddler is for developers, first and foremost, letting you see the messages passing between the browser (or other clients) and the server in HTTP and HTTPS. With the new products, you can also connect to SignalR and gRPC data! Then there are tools for tech support and even embedding capabilities into your applications.

API Management has evolved! Carl and Richard talk to Tom Kerkhove about his new role working on Azure API Management. Tom talks about using Azure Arc to deploy the API Management service into your on-premises services. The conversation digs into more of the fundamentals around API management with rate limiting, authentication and authorization, billing, testing, and more. A good API can make your company money - executed poorly and it's a massive headache. Use the tools available to make it easier!

As of December 13, 2022, IdentityServer 4 is archived - now what? Carl and Richard talk to Dominick Baier and Brock Allen about the long, winding road of IdentityServer growing up to become a commercial product. Dom talks about the challenges of open source and building a sustainable model for an enterprise identity product. Ultimately, it resulted in a transformation from open-source to source-open - so what does that mean? Growth and sustainability!

End of the year, time for a geek out on energy! Richard chats with Carl about the usual modern power generation sources, including solar and wind, and a breakthrough in the drilling method for geothermal energy. The conversation dives into small modular reactors (SMR) and the commitment in Canada to build the first SMR! Molten Salt Reactors have made some progress in 2022, but the extensive conversation is about fusion power. From the NIF announcement to Commonwealth Fusion and others - there's lots to talk about!

How is clean architecture evolving? Carl and Richard talk to Steve Smith about his efforts to build applications using clean architecture principles. The conversation starts with a comment from a listener about idealism around architecture - and a reminder that while there isn't one right way to do anything, using existing work, like clean architecture templates, makes it easier to do the right thing. Steve talks about the various elements that go into clean architectures and how they are often where you end up in development whether you start with a template or not - and how much of a pain it is to course-correct as the project gets larger. Sustainable software needs architecture, and clean architecture is one approach that works - check it out!

How do we learn about application security? Carl and Richard talk to Tanya Janca about her book 'Alice and Bob Learn Application Security.' Tanya talks about bringing positive conversations around security, enabling people to get work done while being secure. Software developers are now targets for the black hats because they often have super-user accounts and aren't following security practices as closely as others. Building secure software means developing it in a secure context - it takes practice, but is the best way to succeed in making secure software!

What's next for C#? Carl and Richard talk to Mads Torgersen about what the team is working on for C# 12. Mads talks about how the language design team is organized to take ideas for C# and explore them, considering all aspects before implementation. The conversation digs into a few of the new features coming and some of the considerations, like breaking changes, that might be necessary to make a feature as good as possible. With C# nearly 25 years old, there is lots of legacy to deal with, but the future looks bright!

What is fusion development, and why do you want some? Carl and Richard talk to Vishwas Lele about his work with teams using the Microsoft Power Platform, including Power Apps and Power Automate. Vishwas talks about getting domain experts more involved in the development process - not just as advisors to the process but as co-creators. The role of professional developers is vital, making effective APIs and even custom-UX components for Power App development. The conversation also dives into the potential of Power Fx, an open-source language that is very much like Excel functions, providing programmability to domain experts - and perhaps a migration path for those company critical spreadsheets!

What does web front-end development look like in 2023? Carl and Richard chat with Amy Kapernick about her work helping companies build web front ends with a vast array of tools. Amy talks about how client frameworks continue to evolve, extending the so-called "big three" of Angular, Vue, and React to focus on different styles. The conversation also ranges over testing web apps, building pipelines for automated testing, accessibility, and more!
