    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 to programming. She finds the dark truth behind the 10x developer, a real definition of “Senior Developer” and a new name for our work and our teams.

    Brendan Gregg - Cloud Performance Root Cause Analysis at Netflix

    60 Mins
    keynote
    Intermediate
    At Netflix, improving the performance of our cloud means happier customers and lower costs, and involves root cause analysis of applications, runtimes, operating systems, and hypervisors, in an environment of 150k cloud instances that undergo numerous production changes each week. Apart from the developers who regularly optimize their own code, we also have a dedicated performance team to help with any issue across the cloud, and to build tooling to aid in this analysis. In this session we will summarize the Netflix environment, procedures, and tools we use and build to do root cause analysis on cloud performance issues. The analysis performed may be cloud-wide, using self-service GUIs such as our open source Atlas tool, or focused on individual instances, and use our open source Vector tool, flame graphs, Java debuggers, and tooling that uses Linux perf, ftrace, and bcc/eBPF. You can use these open source tools in the same way to find performance wins in your own environment.

    Before you can evaluate a method, you have to understand its goals. Before you can evaluate a style of software engineering, you have to understand its goals. Quick execution of experiments? Rapid scaling in the face of unexpected bottlenecks? Sustained, profitable growth? Each goals requires a different style and yet we talk about software engineering as if it should be one thing.
    This talk introduces 3X and the ways software development, quality assurance, design, management, financing, planning, and staffing change depending on the goal of development.

    Anita Sengupta - The Future of High Speed Transportation

    60 Mins
    keynote
    Intermediate

    In the global marketplace that transfers knowledge at the speed of light, we have a massive time delay and that is modern transportation methods. The hyperloop is the first new mode of transport to be created in over 100 years. The motivation is to connect people, reduce congestion, and protect our planet by eliminating CO2 emissions from terrestrial transport. The hyperloop can best be described as space travel on the ground - a magnetically levitating, electromagnetically propelled, passenger vehicle in a vacuum tube. With the elimination of aerodynamic drag and surface friction, power consumption plummets, speeds can reach 700 mph, and waste and cost are minimized. With the use of autonomy the service is on demand and delays become a thing of the past. Dr. Sengupta will discuss how space-age tech coupled to the VC funded innovation environment are enabling the revolution in green transportation from suborbital rocket flights, to electric airplanes, to space travel on the ground with the hyperloop.

    Jutta Eckstein - BOSSA nova: Beyond Agile - Preparing for Digitalization

    50 Mins
    Talk
    Intermediate

    Today companies are expected to be flexible and both rapidly responsive and resilient to change, to both survive but also to thrive on disruptions. These challenges call for company-wide agility. Yet, doing Agile (the mechanics) is different from being Agile (the mindset). For example, substituting management meetings with daily Scrums or using a backlog for the board of directors doesn’t make a company agile.

    In order to become truly agile (meaning flexible, responsive, adaptive, fast, and nimble), you need to think outside the (agile) box. Company-wide agility requires a holistic approach, a combination of different principles: First and foremost the principles of

    • Beyond Budgeting (flexible budgeting & relative targets),
    • Open Space (leveraging the innovative power of all employees),
    • Sociocracy (flexible organizational structures and decentralized decision making), and –of course–
    • Agile (inspecting & adapting).

    We synthesized these proven principles into a wider perspective dubbed BOSSA nova: B = Beyond Budgeting, OS = Open Space, S = Sociocracy, A = Agile. Jutta will reveal a path toward company-wide Agility by showing the synthesis of BOSSA nova.

    The microservice architecture functionally decomposes an application into a set of services. Each service has its own private database that’s only accessible indirectly through the services API. Consequently, implementing queries and transactions that span multiple services is challenging. In this presentation, you will learn how to solve these distributed data management challenges using asynchronous messaging. I describe how to implement transactions using sagas, which are sequences of local transactions, coordinated using messages. You will learn how to implement queries using Command Query Responsibility Segregation (CQRS), which uses events to maintain replicas. I describe how to use event sourcing, which is an event-centric approach to business logic and persistence, in a microservice architecture.

    Randy Shoup - Breaking Codes, Designing Jets, and Building Teams

    50 Mins
    Talk
    Intermediate
    Throughout engineering history, focused and empowered teams have consistently achieved the near-impossible. Alan Turing, Tommy Flowers, and their teams at Bletchley Park broke Nazi codes, saved their country, and brought down the Third Reich. Kelly Johnson and the Lockheed Skunk Works designed and built the XP-80 in 143 days, and later produced the U-2, the SR-71, and the F-22. Xerox PARC invented Smalltalk, graphical user interfaces, Ethernet, and the laser printer. What can this history teach us? Well, basically everything.
    Effective teams have a mission - a clearly defined problem which the entire team focuses on and owns end-to-end.
    Effective teams collaborate without hierarchy, across disciplines and between diverse individuals. It should be no surprise that Bletchley was an eclectic mix of "Boffins and Debs" - almost 75% women at its peak; or that Skunk Works' founding team included the first Native American female engineer.
    Effective teams rapidly learn and adapt. Constant experimentation, tight feedback loops, and a policy of embracing failure are all part of the recipe of success. Innovation does not arrive on a waterfall schedule.
    If this sounds a lot like DevOps, or true little-a agile, that's no coincidence. But too few organizations actually practice these three-quarter-century-old ideas despite the overwhelming evidence that they work. As Santayana wrote, "Those who cannot remember the past are condemned to repeat it." So let's relearn those history lessons.

    Programming is a series of frustrations. Everything we do, we could do better or faster if we only had our tools set up just so. If our error messages were a little better, our code a little cleaner, our tests a lot wider. When we spend time on this, it's known as "yak shaving," and it can get messy.

    How do you balance the work you’re supposed to be doing with the work that makes your work, work? Dive into the yak stack with me. We'll see five different species of yak, and discuss how and when to tackle each one. At the bottom of the yak stack, we might find the Golden Yak, with secret wisdom engraved on its skin.

    This session will give you reasons to spend time smoothing your development experience, and clues for where to spend that time in ways that help your whole team.

    Gary McGraw - How to Avoid the Top Ten Software Security Flaws

    50 Mins
    Talk
    Intermediate

    Software security defects come in two categories: bugs in the implementation and flaws in the design. In the commercial marketplace, much more attention has been paid to finding and fixing bugs than has been paid to finding and fixing flaws.That is because automatically identifying bugs is a much easier problem than identifying design flaws. The IEEE Center for Secure Design was founded to address this issue head-on. My presentation will cover the IEEE CSD’s first deliverable by introducing and discussing how to avoid the top ten software security flaws. The content was developed in concert with Twitter, Google, Synopsys, HP, Sadosky Foundation of Argentina, George Washington University, Intel/McAfee, RSA, University of Washington, EMC, Harvard University, and Athens University of Economics and Business. During the talk, I will introduce and discuss how to avoid the top ten software security design flaws. It's important, of course, to know that these flaws account for half of the defects commonly encountered in software security. But more important still is learning how to avoid these problems when designing a new system or revisiting an existing system.

    When we think of modern data processing, we often think of batch-oriented ecosystems like Hadoop, including processing engines like Spark. However, the sooner we can extract useful information from our data, the better, which is driving an evolution towards stream processing or “fast data”. Many of the legacy tools, including Spark, provide various levels of support for stream processing, but deeper architectural changes are emerging.

    Intermediate

    The most complicated state in an application is time. Like cooking a bag of microwave popcorn, modern web applications desperately try to keep up with their state through an orchestrated chaos of asynchronous operations popping off in indeterminate cadence. No question, coordinating all this concurrency is hard.

    But there's a pitfall at the heart of asynchrony that stays mostly unaddressed.

    When an operation doesn't finish right away, synchronously, it's possible the operation may never finish. Or, it may be destined to finish eventually, but a second operation may be raised which means we no longer care about the first. Whatever the case, we need to be able to cancel it. This critical check ultimately protects users from the vagaries of unpredictable systems.

    Cancellation should be core to our async programming; no asynchrony should run without it. Too often, such handling is just a corner case exception. Without a cancellation strategy, your applications are incomplete at best.

    We'll discuss use-cases for async cancellation and various approaches to managing them.

    We used to build software like bridges. There was time for careful collection of requirements and the analysis of design options. But we don't do that anymore, in part because the time we spent did not ensure we hit our targets or avoided risks. Today, most companies use some form of continuous design where the software changes in small steps, often weekly or even daily, which makes those companies responsive to environmental changes. The problem is that in just a few years the software becomes over-complicated and usually needs to be rewritten, even when the team refactors. The longer you let the team code, the worse the code gets. That's a shame because other kinds of engineering don't have this problem. Car engines, for example, improve every year. I'll primarily discuss some ideas about why things work out this way and also some promising ideas for how we can practice continuous design longer, if not forever.

    Program synthesis is the wild west beyond code generators and onward toward self-programming systems. What can it do for us? The answer, right now, is not a lot. It can harness the wisdom of the crowd to help reproduce scenarios that are repeated often, and in narrow scopes tools can make educated guesses about what the programmer intended, but full automatic program synthesis is likely impossible. Specifically because of this, it becomes most interesting to explore what it can't and won't be able to do on its own. Self-programming systems might be past the horizon, but getting a human more involved makes a big difference, and while the computer might never program for us, it might make for a decent pair-programming partner. We'll look at glimpses of this future, in academia and outside it, and see why they're more IDE plugins and less the robot apocalypse.

    There's more to a Natural Language Processing (NLP) application than an ensemble of models. Much more! Like any traditional application, there is an entire ecosystem of supporting tools that enables core ML functionality. How do you choose the best ones? Which ones can you do without? How do you maintain context when the complexity of such a system gets out of hand?

    In this session, you will learn how to deploy the full scope of an NLP application on Kubernetes with Kubeflow. The guiding principles of a robust and resilient system are explained and used as the foundation for defining a specific architecture. Techniques for modifying and maintaining it over time are described. Find out what Kubeflow currently supports and the long-term vision for the project, presented by a project contributor.

    Success is not determined by our aptitude -- our skill at a particular task. Instead, it is determined by our attitude -- how we go about it. It is far less the contributions of genetics, or education, or circumstance than it is how we approach challenges, limitations, and opportunities in our lives. Through real science and some very personal stories, we will discuss how you can use your attitude to improve yourself.
    We begin by discussing Growth Mindset - Carol Dweck's idea that we can improve ourselves through sustained effort. Focus and attention will help us put in the 10,000 hours of deliberate practice that allow us to achieve mastery.
    We then discuss Trust - by trusting others to do their part and to do it well we can achieve both greater personal happiness and better business results. Generative organizations and psychological safety in teams are key themes.
    We finally discuss Confidence - from the underconfidence of the Impostor Phenomenon to the overconfidence of the Dunning-Kruger effect. Most importantly, we conclude with practical ways you can build and sustain your own confidence in yourself.

    Neal Ford - Building Evolutionary Architectures

    50 Mins
    Talk
    Intermediate

    An evolutionary architecture supports guided, incremental change across multiple dimensions.

    For many years, software architecture was described as the “parts that are hard to change later”. But then microservices showed that if architects build evolvability into the architecture, change becomes easier. This talk, based on my upcoming book, investigates the family of software architectures that support evolutionary change, along with how to build evolvable systems. Understanding how to evolve architecture requires understanding how architectural dimensions interact; I describe how to achieve appropriate coupling between components and services. Incremental change is critical for the mechanics of evolution; I cover how to build engineering and DevOps practices to support continuous change. Uncontrolled evolution leads to undesirable side effects; I cover how fitness functions build protective, testable scaffolding around critical parts to guide the architecture as it evolves.

    The software development ecosystem exists in a state of dynamic equilibrium, where any new tool, framework, or technique leads to disruption and the establishment of a new equilibrium. Predictability is impossible when the foundation architects plan against changes constantly in unexpected ways. Instead, prefer evolvability over predictability. This talk illustrates how to achieve evolutionary architectures and how to retrofit existing systems to support better evolution.
