Databases in Continuous Delivery with Enrico Campidoglio Dec 25, 2014

Show notes

While at NDC London, Carl and Richard talk to Enrico Campidoglio about including databases in your continuous delivery process. Enrico talks through a few different strategies for getting your database moving as fast as your application, without losing data along the way. The conversation digs into issues around version control for databases, keeping schema and reference tables in your source control system, and recognizing that database updates don't happen at the same time as application updates - there can be updates before and after, or otherwise independent of the application itself. Lots of little tips and tricks for managing your database updates more effectively!

Simple.Data.2 with Mark Rendle Dec 24, 2014

Show notes

While at NDC in London, Carl and Richard sat down with Mark Rendle to talk about the latest version of Simple.Data - version 2! Simple.Data started out years ago as a simple abstraction for data access, all open source with numerous additional projects built on it to support a huge variety of data stores. Mark talks about going back into his old V1 project and realizing he did some interesting twists and turns to make it work, and how a rethink of the design brought out the idea of V2. The conversation also digs into the fundraising efforts he did to incentivize getting an alpha version of V2 together. Lots of fun digressions on various projects and ideas as well!

Docker on Windows with Ben Hall Dec 23, 2014

Show notes

Another great show from NDC London, Carl and Richard talk to Ben Hall about Docker. Docker has been taking the industry by storm, bringing a lighter-weight approach to virtualization by getting the operating system out of the package and focusing on automated configuration and implementation. Ben talks about the origins of Docker and its focus on the Linux world - but that is rapidly changing with Microsoft promising an implementation running on Windows. The potential of Docker for facilitating efficient development is obvious, but could this change how we use applications as a whole?

MMS and Space Weather Geek Out Dec 18, 2014

Show notes

Carl and Richard got the amazing opportunity to go to the NASA Goddard Space Flight center to see the James Web Space Telescope in person. And while there, they sat down with Craig Tooley, the Project Manager of the Magnetospheric Multiscale Mission (MMS) to understand a bit more about space weather and the remarkable science and engineering that goes into a mission like MMS. The MMS mission utilizes four identical spacecraft flying in formation to measure plasma interaction effects between the Earth's magnetosphere and the sun. The goal of MMS to capture (by flying through) a magnetic reconnection event, where a huge amount of plasma energy is discharged. As with most things in the universe, reality is a complex thing, and the MMS is at the forefront of our understanding of the universe, at least around our planet!

SPA using Knockout with Steve Sanderson Dec 17, 2014

Show notes

At the NDC London conference, Carl and Richard talk to Steve Sanderson about his work on the Azure Portal and building arguably the greatest Single Page Application (SPA) around today. Steve talks about the approach the Azure Portal team has taken to deal with memory management as well as a flexible plugin architecture that allows the various Azure related teams to plug into the common "shell" component of the Azure Portal. The conversation digs into the challenges of SPAs as the scale and utilization goes up. You can make it work, but it isn't always simple! Steve also discusses the choices you can make around SPAs, it's not just about AngularJS, there are many ways to build a SPA toolchain.

Writing Compilers with Phil Trelford Dec 16, 2014

Show notes

While at NDC London at the Excel Center, Carl and Richard talked to Phil Trelford about building your own compiler. First off, why would you do that? Phil talks about the various ways that compiler technology can be used and help improve your own understand of languages and tools. You probably don't need to replace the C# compiler for your applications, but you might want to use parsing technology to provide algorithmic support in your applications. The power of F# is apparent when you start working on compilers, with its amazing pattern matching and parsing capabilities. Phil also mentions some toolsets to make experimenting with compilers easier, check out the show links for more info!

Starting a Software Business with Liam Westley Dec 11, 2014

Show notes

While at the NDC London conference, Carl and Richard talk to Liam Westley about building your own software business. It starts with the idea that the most destructive thing to your software business is support calls - or more broadly, the accumulated cost of your past business. The conversation digs into the power of being a business of one, rather than having employees, and thinking beyond just your development work, digging into all the other aspects of business: marketing, sales, accounting, and so on. As Liam says, starting a software business is easy, staying in business is hard!

Chrome Developer Tools with Shay Friedman Dec 10, 2014

Show notes

While at NDC in London, Carl and Richard talk to Shay Friedman about the Chrome Developer Tools. The conversation starts out talking a bit about the state of web development, the jump in JavaScript performance, and the huge increase in the complexity of web applications - which naturally leads to the challenge of debugging said JavaScript-based applications. Enter the Chrome Developer Tools. Firefox was the original web developer browser, but Chrome has slid into that slot with more capabilities than ever. More than just element inspection, the Chrome Developer Tools let you look at your web application executing on the browser. Shay talks about tracking down memory leaks in complex Javascript code, where many variables are created, but few are destroyed. You need these tools in your kit!

Hexagonal Architectures in .NET with Ian Cooper Dec 09, 2014

Show notes

While at NDC London, Carl and Richard talk to Ian Cooper about hexagonal architectures. Turns out the important part is not the six sides - it's the idea of ports and adapters. Originally talked about by Alistair Cockburn, this is an architectural approach that focuses on being tolerant to testing as well as separating commands from querying. It's not quite Command Query Responsibility Segregation (CQRS), but you can see it from there! Ian discusses testing in a hexagonal architecture and how Test Driven Development (TDD) works so well with the separation of concerns that ports and adapters offers. If you're working on a long lived application that needs to be maintainable, you should be looking at hexagonal architecture!

Entity Framework 7 with Julie Lerman Dec 04, 2014

Show notes

Julie is back and all about the latest version of Entity Framework - version 7! The conversation starts out with a bit of a state of the union, with Julie describing how moving Entity Framework to GitHub has opened up an amazing level of communication between the EF team and regular developers. Which leads to the scarier part of the discussion: The breaking changes coming to EF7 from EF6. Like ASP.NET vNext, EF7 represents a substantial break. But Julie says you shouldn't worry, there are lots of solutions. Oh, and did she mention that they are planning on including support for non-relational (NoSQL) data stores? Really!
