Could there really be airliners powered by electricity? Time for a Geek Out! The conversation starts out with Richard talking about the Solar Impulse, a single seat aircraft with a wingspan larger than a 747, that has flown around the world powered solely by the solar panels covering it. So yes, electric aircraft are real, but could they be made commercially viable? NASA continues to fund various research projects to improve modern airliners by increasing fuel efficiency, decrease emissions and noise. Electric powerplants could help in all those aspects, but how much power can you pack into an aircraft and how much do you need? We're closer than you think!

What's a really modern web app look like? Carl and Richard talk to Qiming Liu about the Reactive Trader Cloud, demonstrating the synergy between the cloud, containers, microservices, the Reactive Extensions Framework and ReactJS on the client to make a real time currency trader application. The application is on GitHub, you can take it out for a spin for yourself and get a feel for this cool architecture. Qiming talks about treating all data as streams with the Reactive Framework for Javascript, passing messages to the various microservices to complete transactions. Packaging up those microservices in containers allows for resiliency and scalability - you just launch more instances using (in this case) Kubernetes. Check out the code!

What does it take to make an application support multiple customers? Carl and Richard talk to Paul Stovell about his work making multi-tenant applications. As with most things, making multi-tenant apps is more complicated than it seems! Paul talks about making architectural decisions around separation between various customers - do they each get their own database? What about web server and/or app-pool? What about customizations and deployment. Do customers get new features immediately, or do they have the option to wait? How does the cloud impact your decision making? It's a complicated subject with a variety of trade-offs!

How long does it take you to get an idea into a URL? Carl and Richard talk to Daniel Moore about HyperDev - a tool to make the shortest possible path between writing code and putting it online. Initially only implementing Node and HTML, you can use your Javascript skills to build a quick prototype that is easily shareable, even allow multiple people to work on the code together. At this point the system is relatively small, but it's easy to move off onto your own platform once you get your idea to a place where it needs to grow. But perhaps in the future HyperDev will be that place!

F# that transpiles to Javascript! Wait, what? While at NDC is Oslo, Carl and Richard chatted with Tomas Petricek about the Fabel project, combining F# and the Babel project to turn F# into some tight Javascript code. Tomas talks about the easy parts of Fabel first, because Javascript does have some functional elements, and it is possible to write immutable-style code in Javascript if you really want to. Then come the more difficult parts, like typing. There's a judgement call to make about what makes sense in Javascript and what doesn't. But with the choices in where to run Javascript, writing in F# offers some interesting possibilities!

So how's your DevOps doing? While at DevTeach in Montreal, Carl and Richard hosted a panel of Stephane LaPointe, Dylan Smith, William Buchwalter and Alexandre Brisebois to discuss the ups and downs of getting teams to work closer together to make better products and provide better services. The conversation focuses first and foremost on culture - the chant of People, Process and Products around DevOps is not accidental, without a commitment in culture, nothing much can happen. How do we create organizations that are willing to admit failure and make improvements? Does it always have to come from the top? How do you get started down the DevOps path? The panel digs into the questions and more - have a listen!
