Netflix started with a DVD-by-mail product. The software infrastructure and operations practices needed for the DVD business were very different from those needed by a streaming video company. Since the early days of Netflix, CEO Reed Hastings knew that the company would evolve to becoming a streaming video platform. But he did not know when the technology would be advanced enough to support video...

Augmented reality applications can be used on smartphones and dedicated AR headsets. On smartphones, ARCore (Google) and ARKit (Apple) allow developers to build for the camera on a user’s smartphone.

Turn-based games such as Hearthstone and Magic are breeding a new generation of board game and card game aficionados. Social media networks like Twitch and YouTube have turned gaming into a voyeuristic sport that is outcompeting...

Google’s codebase is managed in a single monolithic repository. An engineer at Google can explore almost any area of the codebase within the entire company. In order to enable this, Google has built tooling to support the monolithic repo, including a virtual file system and a set of build tools. A monolithic repository is not to be confused with a monolithic deployment. Google’s infrastructure con...

Africa is rapidly adopting the same software and hardware technologies that have transformed the western world over the last few decades. But access to computers and technology education is still uneven. Where there is access to computers, smartphone adoption often comes before access to laptops or desktop computers. Nelly Cheboi is the founder of TechLit Africa, an organization that works to conn...

Facebook’s strategy is shaped by long term goals, short term requirements, and the available resources of the company. Long term goals are necessary for thinking through big decisions such as acquisitions, hardware product investments, and open source software ecosystems. To implement long term goals, Facebook needs to communicate the vision of the company and foster an internal culture that suppo...

React is a set of open source tools for building user interfaces. React was open sourced by Facebook, and includes libraries for creating interfaces on the web (ReactJS) and on mobile devices (React Native). React was released during a time when there was not a dominant frontend JavaScript library. Backbone, Angular, and other JavaScript frameworks were all popular, but there was not any consolida...

Facebook leadership was able to recognize the importance of mobile computing in time to develop high quality mobile applications, but there were numerous challenges. The Facebook desktop web app had been difficult enough to build due to the unprecedented data requirements and amount of interactivity. Mobile introduced the additional hurdles of limited bandwidth and distinct native operating system...

Facebook is a case study in the ability for developers to self-organize into groups who are working on projects that are meaningful to the company and personally satisfying to the individual engineers. Many engineers in the software industry work under a less capable manager who has complete control over their creativity. This leads to employee churn, dissatisfaction, and burnout. Facebook’s abili...

Facebook engineering is commonly described by two words: move fast. Building products quickly has been a differentiating characteristic of the company since its inception. From the longtime engineers to the summer interns, Facebook instills a sense of immediacy and opportunity in all of its employees. The goal of Facebook is to make the world more open and transparent, with the intention of creati...

Software engineering is harder than it should be. There are many people who have an app idea that they are not sure how to build. Some of these people are highly technical professionals like real estate agents, scientists, and accountants. These professionals learn to use spreadsheets in their day-to-day work. Spreadsheets are also used widely by young people such as students. Spreadsheet users va...

Relational data systems have evolved from single node instances to complex distributed systems. Almost any database can be accessed through a SQL statement, but the guarantees of these databases can vary in terms of consistency, availability, latency, durability, and financial cost. Relational database systems that explore these different sets of tradeoffs are sometimes categorized as “NewSQL”. Th...

WebAssembly is a binary instruction format for applications to run in a memory-constrained, stack-based virtual machine. The WebAssembly ecosystem consists of tools and projects that allow programs in a variety of languages to compile into WebAssembly and run in a safe, fast, sandboxed runtime environment. WebAssembly is a transformative technology for the Internet. Most users will experience it a...

Modern server infrastructure usually runs in a virtualized environment. Virtual servers can exist inside of a container or inside of a virtual machine. Containers can also run on virtual machines. Kubernetes has allowed developers to manage their multiple containers, whether those containers are running in VMs or on bare metal (servers without VMs). As organizations expand their Kubernetes deploym...

Relational databases such as Postgres are often used for critical workloads, such as user account data. To run a relational database service in the cloud requires a cloud provider to set up a highly durable, highly available system. Jon Daniel is an infrastructure engineer at Heroku. Jon joins the show to describe the engineering and operations required to build a managed relational database servi...

Satellite images contain vast quantities of data. By analyzing the contents of satellite images over time, we can identify trends in weather, soil, and agriculture. If we combine that data with ground-level sensors, we can gather a clearer understanding of how chemicals in the air or in the dirt map to how things look from above via satellite. Descartes Labs is a company that gathers high dimensio...

The modern software supply chain contains many different points of distribution: JavaScript frameworks, npm modules, Docker containers, open source repositories, cloud providers, on-prem firmware, IoT, networking proxies, and so much more. With so much attack surface, securing a large enterprise is an uphill battle. Jeff Williams is the CTO at Contrast Security, a company that makes infrastructure...

Growing a software business requires an understanding of engineering, sales, and marketing. As we learn software engineering, we also pick up some knowledge about how a business should operate. We know that there are customers, and that our product needs to be scalable to serve more customers. We know that some features are more important than others, and so we focus on building the features that...

A Kubernetes instance occupies a wide footprint of multiple servers, creating an appealing target to an attacker, due to its access to a large pool of compute resources. A common attack against an exposed Kubernetes cluster is to take it over for the purposes of mining cryptocurrency. Thus it is important to keep a cluster secure. The importance of security is magnified for a cloud provider. A clo...

To the extent that I am a software engineering journalist, I feel inclined to scrutinize all of the cloud providers. But to the extent that I am an engineer and a business person, I feel only admiration and love for the cloud providers. Cloud computing has brought the cost of starting an Internet business down to zero. Cloud computing has opened up my eyes to a world of creative possibilities that...
