React Data Flow with Jared Forsyth
React started as just a view layer–it was the V in MVC. React has moved down the stack, with Flux, Redux, GraphQL, and Relay providing opinions for how React applications should structure their data flow. Jared Forsyth works at Khan Academy, which uses React on the front end. At Khan Academy, Jared has experimented with many different ways of handling data flow for a React application, and in today’s episode we not only discuss the conventional tools for React applications, but also ClojureScript, Reframe, and Om/next, which are solutions for React data handling, that are outside of the world of raw JavaScript.

Mobile Apps and Monetization with Mike Wakerly
Applications on your phone can talk to each other, but the way that apps interact is still far from the way that web pages interact. Mike Wakerly is the CTO of Button, a service that connects mobile apps to each other. By embedding a component from Button into your app, you can easily request the functionality of an app while you are in a different app. In this episode, Mike and I discuss the future of mobile, and the problems of app stores today. We also explore how mobile application context switching has improved, and how that creates business opportunities that are much more interesting than advertising.

Open Source Pancreas with Dana Lewis
Patients with Type-1 diabetes need to frequently pump insulin into their bodies. In order to know when to pump insulin, these patients have a continuous glucose monitor alarm which detects incorrect levels of blood glucose. When the alarm goes off, the diabetes patient administers insulin manually through the pump. In an ideal world, the alarm would communicate with the insulin pump, creating a closed loop. But the world of outdated medical devices is not ideal. Dana Lewis is a developer of an open-source, closed-loop artificial pancreas called the Do-It-Yourself Pancreas system. Dana joins the show to discuss how she hacked together her artificial pancreas using a Raspberry pi plugged into these medical devices. This is a fascinating story of reverse engineering, internet of things, and the hacker mentality. Sponsors

Falcor at Netflix with Brian Holt
At Netflix, building a user interface requires data about movies, actors, users, accounts, and much more. If each piece of data is coming from a different source, a programmer has to call each of the services that has access to that data. Falcor is a piece of technology designed at Netflix to solve this problem. Falcor creates a unified JSON model of all of the data you could want–and Netflix engineer Brian Holt joins us today to discuss how Falcor works. We also discuss React, ES6, and JavaScript at Netflix, and Brian explains why Falcor is extremely similar to GraphQL, and why that is OK.

Kubernetes, Docker, and the Distributed Operating System with Kelsey Hightower
Kubernetes is an open-source distributed operating system that allows normal engineers to manage their resources at the scale that Google does. With Docker providing the APIs to make containers easy to work with, Kubernetes allows processes to be easily distributed and replicated across a data center. Kubernetes was created at Google, and today’s guest Kelsey Hightower is a staff developer advocate working at Google. He joins me in a conversation about how Kubernetes works, and why it is important to an average developer. We touch on how software engineering is going to look in the next 5-10 years, and how a lot of the work around distributed systems will become much easier over time.

Distributed Systems and Exception Monitoring with Brian Rue
Exception monitoring services and log management services are two sides of a gradient. Exception monitoring services capture and aggregate the problems that occur on your application. Log management services aggregate all of your logs, so that you can decide for yourself what constitutes a problem. Brian Rue from Rollbar joins the show today to talk about Rollbar’s exception monitoring architecture, and the competitive landscape of these technology products. Every software engineer wants track the problems with an application, but some developers need more information than others–and that ends up changing how these error aggregation services are architected. This is an interesting conversation on the business of SaaS products for developers, and the architecture of a distributed system designed to monitor and aggregate errors.

Azure Event Hubs and Kafka with Dan Rosanova
Apache Kafka has become the most popular open-source solution for persistent replicated messaging in the Hadoop ecosystem. But some software engineers who are working with “big data” don’t want to deal with the configuration and set up of Kafka. One way to side step this problem is to go with a managed solution, like Microsoft Azure Event Hubs. Dan Rosanova is today’s guest. He joins us to discuss persistent replicated messaging, and the features that Azure Event Hubs provide. This is an interesting discussion about distributed pub sub messaging, and we also get into a great conversation about platform as a service versus open source software, and the future of cloud software.

Reverse Engineering Facebook with Alex Hogue
“Graphing when your Facebook Friends are awake” was trending at the top of Hacker News when Alex Hogue first posted it. Alex wrote a blog post about this piece of software he built that interacts with public Facebook APIs to detect when any of his friends are awake or asleep. As I read that post, I wanted to talk to Alex, because it was such a creative and technical piece of software–but it is surprising that someone would take the time to randomly inspect the elements of the Facebook page, reverse engineer the way Facebook sends data about statuses, mine data from that reverse engineering, and create a bunch of graphs about that data. Today, Alex joins me to explain how and why he built a tool to graph when people are awake or asleep using Facebook data.

Elixir and Erlang with Jose Valim
Elixir is a programming language built on top of the Erlang virtual machine. Elixir allows metaprogramming, polymorphism, and a web framework called Phoenix that has drawn positive comparisons to Ruby on Rails. Jose Valim is today’s guest. He built Elixir to augment a language that he loved–Erlang. On Software Engineering Daily, we interviewed Joe Armstrong, the creator of Erlang, which was a very popular show–I encourage any listeners who are fans of Erlang to check it out. Erlang was built with concurrency in mind, and it has been rising in popularity as more of our applications are written to be distributed. In today’s episode we will discuss what Jose is building on top of Erlang.

Search as a Service with Julien Lemoine
Engineers who want to add search to their application usually deploy Elasticsearch, or write their own search engine that uses TF-IDF. These solutions work well for large documents, but are less effective for large volumes of small records–which is how many modern web and mobile applications are structured. In today’s show, Julien Lemoine discusses how his company Algolia thinks about search. Algolia is a search as a service company that gives developers an easier way to search on their websites and applications.

Creating the Wiki with Ward Cunningham
Wiki technology was invented decades ago to improve how software developers communicate. Today, Wikipedia has taken the ideas of the wiki to a new level, creating a free knowledge graph for the world to learn from. Ward Cunningham developed WikiWikiWeb in 1994. He joins us today to discuss the first wiki, and how wikis have changed the way information propagates. Ward is not just an expert on how to write software–he is an expert on the software development experience, and we discuss how to build a community where software developers can overcome the fear of building something that has not been built before.
