🐤🦈Shark: Diving into the guts of LeakCanary's Hprof parser
LeakCanary, a memory leak detection library for Android, was slow and used a lot of memory. For LeakCanary 2, I wrote a new heap dump parser, Shark, which uses 10 times less memory and is 6 times faster. Come learn about the gory implementation details and performance tricks!
We'll dive to the byte level then build our way up to efficiently compute shortest paths and dominators (graph theory without any math!), then use profiling tools to optimize algorithms and data structures where it matters. And of course it'll be 100% Kotlin.
Pull requests 👨💻, yoga 🧘♂️ & avocado toasts 🥑: 7 ans d’engineering à Square ✨
En 2013, j’ai eu l’opportunité de déménager à San Francisco pour rejoindre l’équipe Android de Square. J'y ai beaucoup appris et découvert de nombreuses pratiques que j’aimerai partager avec l’audience. Ces pratiques sont parfois individuelles, parfois collectives, parfois du Software Engineering et parfois plus générale. Et probablement pas Scum Master frAgile certified ;-) . Quelques sujets parmi la multitude abordée: Design Docs, transparence, core team vs décentralisation, méditation, le secrets des entretiens de code…
PokeLeaks: Gotta Catch 'Em All 🐤🔍
Bring your laptops and your investigative skills, we're going on a memory leak hunt!
We'll check out the repository of an app that contains hidden memory leaks, add LeakCanary, and start finding leaks. You have one job: fix all the leaks!
The goal of this session is to learn how to use LeakCanary and investigate its analysis reports. If we have extra time we can also look into tricky leaks in your own app.
MILK: a user-centric mobile performance model
Over the last few years, Block (the company formerly known as Square) focused on improving app performance as perceived by our customers as they experience our products. To that end, we defined a user-centric performance model that provides a structure for thinking about app performance: the Motion Idle Latency Kit, a.k.a. MILK.
This talk will provide a comprehensive view of how we approach app performance, with practical advice & guidance that should work for most companies.
Human Centered API Design
Have you ever wondered why some APIs are a pain to use (fragments cough cough), while others are pure joy? API design is perceived as a craft, something that we get better at by learning best practices and applying a set of rules. Read Effective Java & Clean Code, that should be enough, right?
At Square, we wanted to create a remarkable API for a new SDK, and I started researching the topic of usability and API design. It turns out that there's a science to this madness, and we can all learn to build better APIs without just blindly following good practices. Come to this talk to learn the practical steps we took to get there.

[Panel] Apps at Scale: An Industry Discussion
What makes app development with 50 engineers different than 5?
What do you need to support 100's or 1000's of modules?
In this panel, we'll have representation from engineers who've worked on the infrastructure and platforms for some of the largest apps to discuss their various approaches to tooling, process, and organization.
