Engineering managers face a different set of problems than engineers themselves. Whether they are hiring new employees, firing underperformers, or guiding a team of existing engineers, engineering management is all about people. Empathy is paramount because management is like being a professional therapist for the members of your team. Mike Borozdin has been managing engineers for more than a deca...

Open source software is publicly available code that is worked on in the open by large crowds of developers. Almost all new software today uses some open source software in its code. But most people never contribute to open source themselves. Some people would love to get involved in open source, but they don’t know how to get started. Shubheksha Jalan found herself in this position. In her early...

Giphy is a search engine for gifs, the short animated graphics that we see around the Internet. Giphy is also a creative platform where people create new gifs. Every search engine requires the construction of a search index, which is a data structure that responds to search queries efficiently. Since Giphy is a search engine for graphics, there is almost no text inherently associated with the each...

Cloud computing has pushed computation away from our own private servers and into virtual machines running on a data center. In the world of cloud computing, processing is centralized in these data centers, and our smartphone and laptop application performance suffers from having high latency between the client and the cloud server. As machine learning proliferates, the current model of cloud comp...

What is the relationship between your brain and your conscious experiences? This is is the fundamental question of the work of Donald Hoffman, a professor of computer science and cognitive science at UC Irvine. When Hoffman was a child, he wondered whether there was a cognitive dividing line between humans and machines, and that curiosity has driven him to his current work–building a mathematical...

Software developers succeed by combining technical ability, communication skills, and well-reasoned philosophies to craft information systems. Where this podcast focuses on the information systems, Developer On Fire focuses on the engineers who built them. Dave Rael started his podcast as a way to overcome fear and access an entrepreneurial side of himself. In his interviews with prominent enginee...

Back in 2008, the range of tools that engineers could use to connect computer systems together were getting quite good. Cloud computing was democratizing access to servers. But the telephony ecosystem was still inaccessible to the average developer. If you needed your program to make a phone call and connect a user to a customer service representative, there was no easy way to do that. Twilio was...

Engineers today have a variety of career options. You could go work for a large corporation, you could raise money and start a startup, you could freelance and move from job to job with freedom–or you could start a business with the goal of quickly becoming profitable. Courtland Allen was a guest on Software Engineering Daily a few months ago, when he discussed Indie Hackers, a platform he built t...

Many elderly people live with unhealthy levels of isolation. Social isolation is a problem for anybody, but younger people can use technology to alleviate their isolation with tools like Skype and Facebook. How can we bridge the generational gap and give elderly people access to the same technological tools that younger people find easy to use? Voice interfaces are an important new medium for comm...

Whatever engineering problem you have right now, the solution is probably not to write a new programming language. But sometimes it does make sense. JetBrains makes IDEs–the interactive development environments that many people code in, like IntelliJ and Webstorm. And all of these IDEs are written in Java. So the JetBrains team is very familiar with Java and the JVM. Since JetBrains spends so much...

Translation is a classic problem in computer science. How do you translate a sentence from one human language into another? This seems like a problem that computers are well-suited to solve. Languages follow well-defined rules, we have lots of sample data to train our machine learning models. And yet, the problem has not been solved–largely because languages don’t always follow rules. We have idio...

The goals of microservices are the same as what we have pursued in software engineering for decades: isolation, decoupling, maintainability, scalability. The reason that we use the term microservices is not because we have a completely different idea of what a service is than we used to. We use the term microservices because we are signaling that we need to achieve these architectural goals in a d...

Building a mobile app requires developers to build a separate version for Android and iOS. The approval process for app stores makes it difficult to deploy quickly and iterate in small batches for developers who are making native apps. These frictions cause fewer developers to write mobile apps than we would have if the smartphone platform was unified. Since the early days of the smartphone, diffe...

Urbit is a completely new way of looking at computing. Every user gets a personal server, which runs your apps, wrangles your connected devices, and defines your secure identity. Your urbit presents your whole digital life as a single web service. Urbit feels foreign and confusing for those of us coming from the traditional web because the normal paradigm is to iterate and paper over the problems...

Over the past few years, React has become the most popular front end JavaScript framework. As React has matured, the open source community around React has identified areas for improvement. Since React itself is too mature to refactor completely, new projects have been started to take the best aspects of React and start from scratch. Inferno is an extremely fast, React-like JavaScript library for...

Product managers are responsible for guiding the design and overall functionality of software. The relationship between product managers and engineers is complimentary: a PM is viewing the product from a perspective that is closer to the customer, so the PM often has the responsibility of navigating high-level tradeoffs in the functionality of a product. Suzie Prince is the head of product at Thou...

Medical imaging is used to understand what is going on inside the human body and prescribe treatment. With new image processing and machine learning techniques, the traditional medical imaging techniques such as CT scans can be enriched to get a more sophisticated diagnosis. HeartFlow uses data from a standard CT scan to model a human heart and understand blockages of blood flow using simulations...

Data visualization tools are required to translate the findings of data scientists into charts, graphs, and pictures. Understanding how to utilize these tools and display data is necessary for a data scientist to communicate with people in other domains. In this episode, Srini Kadamati hosts a discussion with Jake VanderPlas about the Python ecosystem for data science and the different attempts at...

Column-oriented data storage allows us to access all of the entries in a database column quickly and efficiently. Columnar storage formats are mostly relevant today for performing large analytics jobs. For example, if you are a bank, and you want to get the sum of all of the financial transactions that took place on your system in the last week, you don’t want to iterate through every row in a dat...

Free Code Camp is an online learning platform that takes people from knowing nothing about code to having enough knowledge to build software for a living. We have already done a show with Quincy Larson, the founder of Free Code Camp, in which we discussed his motivation for starting the organization. The economics of running a free interactive platform with thousands of users informs the architect...

Software engineers are often one of the last lines of defense against potentially dangerous and unethical practices. Every software company encounters situations where the line between right and wrong is not clearly drawn. Back in the year 2000 Bill Sourour was asked to code a project to help market a pharmaceutical product in a misleading way. Reflecting on this experience, Bill recently wrote ab...

A company like Pinterest has millions of transactional emails to send to people. The scalability challenges of sending high volumes of email mean that it makes more sense for most companies to use an email as a service product rather than building their own. Chris McFadden is the VP of engineering and cloud operations at SparkPost and he joins the show to explain the architecture of SparkPost’s em...

Vulnerabilities exist in every computer system. As a system gets bigger, the number of vulnerabilities magnifies. The web is the biggest, most complex computer system we have–but fortunately, the steps we can take to secure our web applications are often quite simple. Jared Smith is a cyber security research scientist with Oak Ridge National Laboratory. He joined me on the show to discuss web appl...

Meetup is an online service that allows people to gather into groups and meet in person. Since 2002, the company has been growing and its technology stack has been changing. Today, they are in the process of migrating to the cloud, using both Amazon Web Services and Google Compute Platform. Yvette Pasqua is the CTO of Meetup and she joins the show to explain how Meetup’s technology stack works and...

When a useful new technology comes out, companies that are in a position to adopt that new technology can gain an edge over competitors. As our industry grows and moves faster, these kinds of changes are coming faster–some recent examples are Docker, ReactJS, and Kubernetes. Evolutionary architecture supports incremental, guided change as a first principle along multiple dimensions. A company with...
