    Dave Farley - Taking Back “Software Engineering”: Craftsmanship is not Enough

    60 Mins
    Keynote
    Advanced

    Would you fly in a plane designed by a craftsman or would you prefer your aircraft to be designed by engineers? Engineering is the application of iterative, empirical, practical science to real-world problems. Craftsmanship is a wonderful thing, and as a reaction to the terrible abuses of the term Engineering in software development Software Craftsmanship has helped in our learning of what really works.

    The term "Software Engineering" has gained a bad reputation. It implies "Big up-front design" and "Mathematically provable models" in place of working code. However, that is down to our interpretation, not a problem with "Engineering" as a discipline.

    In recent years we have discovered what really works in software development. Not everyone practices approaches like Continuous Delivery, but it is widely seen as representing the current state-of-the-art in software development. This is because at its root CD is about the application of an iterative, practical, empirical, maybe even science based approach to solving problems in software development. Is this a form of software engineering?

    Software isn't bridge-building, it is not car or aircraft development either, but then neither is Chemical Engineering, neither is Electrical Engineering. Engineering is different in different disciplines. Maybe it is time for us to begin thinking about retrieving the term "Software Engineering" maybe it is time to define what our "Engineering" discipline should entail.

    If code is the colouring pens and lego blocks of our times – the tools of creation – how do we teach the curiosity, joy and wonder to our kids? I spent last summer looking at programming and play: how to create experiences that go deeper than just learning logic. So, just like Alice, I swallowed the blue pill and fell down inside the machine. This talk summarises my three principles of play and a few experiments I’ve learned with little Ruby and the journey I’ve been on with her

    Gregor Hohpe - Enterprise Architecture = Architecting the Enterprise?

    60 Mins
    Keynote
    Advanced

    Architects in the enterprise are often regarded as ivory tower residents who bestow their utopian plans upon project teams in the form of colorful diagrams that bear little to no resemblance to reality. The most suspicious in this group are often the “Enterprise Architects” who are perceived as being furthest from actual technical problems.

    However, large-scale IT operation and transformation require transparency across hundreds or thousands of applications running on all sorts of middleware in data centers around the globe. The very enterprise architects are likely the only ones who stand a chance to bring transparency into such an environment and who can direct IT investments in the hundreds of millions of Euros towards modernization and run-cost reduction. This sounds a lot more exciting and valuable than drawing pictures!

    This session takes a serious but light-hearted look at the role of enterprise architects in modern IT organizations.

    GraphQL has been out in the wild for nearly 2.5 years now. For such a relatively young API technology, GraphQL has won hearts and minds and it's being used in some rather unexpected places. The Community has grown rapidly and created a rich ecosystem of extremely useful tooling.

    Josh will present a quick introduction to the basics of GraphQL as well as a high-level overview of the GraphQL ecosystem. He'll also describe some of the benefits of using GraphQL in your API layer, bust some myths around what it is and what it isn't, as well as some of the ways you can get started with GraphQL easily in your projects.

    In this talk, we have a look at some of the low-hanging problems in general aviation and how functional programming can be applied to provide significant improvements in efficiency and air safety. The current solutions to problems such as navigation, traffic/terrain collision avoidance and weight/balance calculations will be demonstrated to the audience, mostly for amusement. More seriously, we will have a look at the legacy that has led to the way things are, and how to improve by applying our programming skills.

    We will look at:

    • how aviation safety is regulated.
    • how aeronautical services are provided to flight operators.
    • how aeronautical navigation is conducted and regulated.
    • how the weight and balance for a flight is conducted.
    • the methods by which aircraft and ground coordinate between each other.

    We will see:

    • some real (and basic) data management problems in aviation, that very obviously threaten safety, then solve them, using programming.
    • we will see a live demonstration of aeronautical navigation methods, investigate incident reports where lives were lost as a result, and consider how our programming skills can yield improvements, possibly even save lives.
    • we will conduct a real weight&balance calculation for a flight, then once hilarity inevitably ensues, we will look at the problems that arise by this method, then solve them using data structures and functional programming. Some of these practical problems are obvious, even to a non-aviator, and the predictable incident reports are the end result.
    • finally, we will have a look at a live demonstration of a software defined radio (SDR), receiving ADS-B transmissions from aircraft (live), an AHRS implementation and GNSS receiver using off-the-shelf, low-cost parts. We will look at why these instruments are helpful to aircraft pilots and interact with that device using the Haskell programming language.

    Deep Learning has led to breakthroughs in many previously unsolved problem domains, from image classification to machine translation to medical imaging analysis. Venture capital firm Andreessen Horowitz recently cooked up an AI playbook, which posits that AI will impact software as broadly as relational databases have since the late 20th century. It’s hard to think of a technological problem that AI doesn’t touch.

    In this talk, we will explore the limits of today’s most popular approaches to AI. In particular, what kinds of problems can’t we solve today and how might the solutions shape the way we approach software development? Training a model for your particular domain is easier than ever, but why is it so difficult to make sense of what is going on inside the model? How can we move toward a more intuitive and accessible model for understanding what our AI has learned?

    There might be 25 or more Kalman filters or variants thereof in your phone and its apps. This essential class of algorithm empowers every aspect of navigation, tracking, control, and beyond to business, finance, and machine learning. Kalman filters can be tricky to test and tune, and it's essential that exactly the same code as was tested be deployed. But Kalman filters are just foldable functions! I show how to fold exactly the same code over repeatable data in a friendly testing environment and over asynchronous data in a harsh, real-world environment.

    Mike Amundsen - Twelve Patterns for Evolvable Web APIs

    50 Mins
    Talk
    Advanced

    The speed of feature release for web and mobile apps continues to increase, but it can grow costly and time consuming to constantly rebuild and redeploy client applications—especially through app stores, where updates can take more than a week to appear. What if you could add new features to an existing client without repeatedly installing new versions of the application? What would the code look like? What changes are needed to create a client that can adapt to changes in the service API? How much change is reasonably possible when both the client and API are able to evolve over time?

    Mike Amundsen offers 12 patterns and practices for building APIs that can safely evolve over time and client applications that can adapt to those changes without relying on explicit versioning systems or repeated redeployment. Whether you are responsible for building web front-ends or APIs to serve those apps, Mike helps you identify key principles to increase the adaptability and evolvability of your web implementations.

    Facebook has been using GraphQL queries to build rich user experience on web and mobile. User interface updated in real time as other users interact with the system plays a key role in driving user engagement. LiveQueries is an API to allow building interactive user interface, update client caches, push updates to the client in the background and more. It allows subscribing to the query result and receive updates as the query result changes.

    LiveServer is a stateful back-end for LiveQueries which interacts with query execution engine and reactive data sources. It uses dependency tracking and query re-execution to send updated query results to the client. It also allows delayed query execution and application of strategies for failed client message deliveries. Client and server is using long living connections and RSocket application protocol to deal with subscriptions, bi-directional streams, flow control and connection resumability.

    How are microservices in 2017 different from how we used to build them at the beginning of the decade?

    More traditional Service-Oriented Architectures were defined by protocols and standards published and curated by industry consortiums. Knowledge of the architectural style usually called "microservices", on the other hand, is often in the form of patterns, cautionary tales, and tools extracted from real-world reports and software made available by organisations that have adopted this style.

    Almost ten years since the first wave of such reports, the landscape has changed considerably. Many hard challenges from the past have been eased or completely solved, and a lot of the custom software created by the microservices pioneers have been made off-the-shelf open source software.

    In this talk, Phil Calçado will contrast what we first found in the first generation of microservices architectures against the current generation's landscape. Let's talk about which previous common knowledge and patterns are deprecated, which ones are still active, and introduce some of the ones that have been recently added to our toolbox.

    The software development industry has made huge leaps in recent years; with agile, lean, software craftsmanship, evolutionary design and microservices being just a few of the buzzwords we throw around. Despite this, software development teams are often more chaotic than they are self-organising, with the resulting code being more of a mess than was perhaps anticipated. Successful software projects aren't just about good code though, and sometimes you need to step away from the IDE for a few moments to see the bigger picture. This session is about that bigger picture and is aimed at software developers who want to learn more about software architecture, technical leadership and the balance with agility.

    This talk will debunk some of the common myths as we look at five things every developer should know about software architecture; a guide to software architecture on modern software projects that's pragmatic rather than academic and lightweight rather than "enterprisey".

    Test-Driven Development (TDD) has been so successful that it’s now unfashionable. But many developers complain that being required to write tests just gets in the way of shipping features. That wasn’t our experience when we first stumbled onto TDD a dozen years ago, so what went wrong? Were we fooling ourselves, or did the message get confused along the way?

    In this talk, I will revisit the basics, the essence of what makes TDD work. I will look at some of the common difficulties that I see with teams that are struggling. I will show how understanding the principles means that we can use tests to help us deliver more effectively.
