Airlock - Facebook's mobile A/B testing framework

Posted about 4 years ago
blog post · Mobile · Testing · iOS · Android · Platform

Two years ago, we rewrote our mobile apps on iOS and Android to use the native development stacks in place of the custom web-stack we had been developing. This gave us finer control over when and how items were downloaded, cached, and freed. It also opened up access for deeper integration into the respective operating systems and revealed a full toolbox for tuning and tweaking all systems under the hood. With this shift, we needed a new mobile A/B testing infrastructure that would let us expose our users to multiple versions of our apps (version A and version B), which are the same in all aspects except for some specific tests. So we created Airlock, a testing framework that lets us compare metric data from each version of the app and the various tests, and then decide which version to ship or how to iterate further.

A little over two years ago we launched Messenger to give people passionate about messaging a simpler and faster way to communicate with their friends. As features have been well received by our Messenger users we've brought them over to our core Facebook apps. As a result, the Messenger and messaging experience across Facebook became very similar.

Secure browsing by default

Posted about 4 years ago
blog post · Web · Infra · Mobile · Security · Android · iOS · User Experience · Networking and Traffic

We now use https by default for all Facebook users. This feature, which we first introduced as an option two years ago, means that your browser is told to communicate with Facebook using a secure connection, as indicated by the "https" rather than "http" in https://www.facebook.com. This uses Transport Layer Security (TLS), formerly known as Secure Sockets Layer (SSL), and makes the communication between your browser and Facebook servers more secure. Read more...

Product engineering at Facebook

Only a few years ago, 10 engineers were responsible for innovating, building and maintaining all of the products (a.k.a. features) on Facebook, including Profiles, Pages, Groups, Messages, Photos, and Events. These people were our first product engineers, a role that is a mix of generalist engineer, product designer, and product manager. Read more...

Interning at Facebook: Building the new mobile advertising interface

Posted about 5 years ago
blog post · Mobile · Culture · iOS · Platform · User Experience · Bootcamp · Academics · Recruiting

Before starting my internship at Facebook, I was told that intern mentors focus on impact when assigning projects. Originally I thought this meant I would be writing unit tests that ran on a lot of servers, or maybe writing documentation that many people would read. I learned instead that mentors have the ability to assign interns critical features in a product’s roadmap. Receiving such a project can be intimidating, but when the intern rises to the challenge, the payoff is huge. Read more...
