Many believe that better security comes from robust independent gating, but DevOps has proven that you can safely deploy orders of magnitude faster without human gating. Comcast uses a DevSecOps approach which focuses on automation, speed and team ownership of end-to-end product security lifecycle. It’s agile and developer-focused. It’s about building security in rather than bolting it on. Learning Objectives:...

It's been ten years since the first mainstream distributed databases launched. In that time, we've seen hype (NoSQL/NewSQL will do everything!), disillusionment (you still can't beat the CAP theorem), and consolidation (to basically Cassandra and MongoDB). Meanwhile, the big three cloud vendors each launched their own products, and the industry is collectively starting to understand their role in building modern...

Functions are the key superpower enabling serverless architectures. Certainly the low cost of only paying for what you use (100% utilization) is a nice benefit. And no doubt there are operational savings by only focusing on your business logic instead of managing a brittle and complicated infrastructure. But designing with functions as the smallest unit of deployment also confers a...

They said Swift is “protocol oriented,” so you wrote protocols. But you wanted them to be generic, so you added associated types. But your collections broke, so you added type-erasers. But your “as”-casts broke, so you switched to Any. But then everything broke, so you read about Mirror. And the tears began. Why did it have to be so hard...

AWS has made our life easier. And it has made scaling easier – but too often, when you go to scale, it's a matter of reaching for the credit card to add more, more, more. Soon, you're in Cloud Jail. Learn how we dealt with this at TUNE, and how we ultimately did a jailbreak.

So you want to connect a "thing".... or many "things"? In this journey, you need to make a very important decision (among many): which wireless protocol is right for your use case and how do you choose your platform? At the end of the day, no matter how good your application, if you don’t have reliable connectivity, you just have...

Abstract: Since last ETE, we've seen two more major versions of the JDK! What's changed in the last year, and what's coming down the road? Join Java Language Architect Brian Goetz in a whirlwind tour of just some of the features coming to Java next.

As technologists, it’s our job to stay on top of, and advocate for, new approaches. There are many valid reasons an enterprise might want to adopt cutting edge or experimental technology. That said, gratuitous use of technology without a well-vetted business case can be exceedingly costly and more likely to stifle innovation than support it. It’s easy for a new...

There’s a story to tell, about musicians, artists, philosophers, scientists, and then programmers. There’s a truth inside it that leads to a new view of work, that sees beauty in the painful complexity that is software development. Starting from The Journal of the History of Ideas, Jessica traces the concept of an “invisible college” through music and art and science...

This talk is about the fictitious divisions we invent, and how they harm the progress of our industry. In particular, we'll look at the supposed tension between Functional Programming and Object-Oriented Programming, and hopefully see that the tension is all in our heads.

An inspiring talk about mentoring the next generation.

In the Java ecosystem, we have historically been enamored by the concept of the "Application Server," the runtime engine that not only gave us portable APIs (e.g. JMS, JAX-RS, JSF, EJB) but also gave us critical runtime infrastructure for things like farm deployments, configuration, load-balancing, fail-over, distributed management and monitoring. In this session, we are going to demonstrate how Kubernetes...

I'd like to introduce you to this new, 60 year old, kid on the block: "Machine Learning". Some math + some stats, but mostly "what"s, "why"s and "how"s of different problems it solves, and of course some code, since that's what machines speak best. While we'll ride along with mouthfuls such as "stochastic gradient descent", "cross entropy" and friends, the...

GraphQL is a client/server API specification for submitting queries, updates and subscribing to data, and it's been an interesting replacement technology for JSON in single page applications. Originally created for the Facebook application in 2012, it began life serving the graph of connections between people, posts, and other related data. Ultimately, Facebook open-sourced the relay server and the API was...

Great automation doesn’t replace humans; it enhances us. When we are choosing or building tools for our team, we want them to play like team members: keep us informed, make the easy decisions repeatably, and pass the hard decisions to the humans along with the information we need to make them. Based on research in human-centered design, this talk enumerates...

Hear about how Rust Editions evolve the language and the compiler without breaking existing code. See who's trusting Rust for critical products today. Join us on Rust's journey to the future.

Serverless applications are the future of lightweight, scalable, and performant application development. Developers are breaking apart their monolith applications into smaller, purpose-focused microservices. They are quickly and purposefully prototyping application ideas. Moving to a “Serverless” environment really means to migrating a fully-hosted environment to using a fully-managed compute or persistence service from one of the big cloud platform providers. One...
