    Functional Examples from Category Theory

    Many concepts from Category Theory appear in functional programming languages, for example the functor, monoid, monad, and natural transformation. Although each of these concepts carries with it a distinct structure, each provides us with a way to unite the similarities in a piece of code, or even across and entire project, while still maintaining the crucial differences. Category Theory gives us the means to abstract over concepts such as types, type constructors, and operations, to name a few. In other words, Category Theory is the programmer's library of abstractions.

    Functional languages, by their very nature, often direct the programmer to think abstractly in terms of categories. From a meta perspective, learning Category Theory helps us to become aware of the types of thoughts we have when we program in a functional language, versus say an imperative one. Programming in a different language inherently changes how we approach a problem, given the tools available in that language. By becoming aware of those differences in approach, we can make more informed choices in our programs.

    In this talk we will discuss via example how we can understand various functional programs using a categorical approach. Additionally, we will discuss how we can use Category Theory to write cleaner and more maintainable code.

    Building a Distributed Data Ingestion System with RabbitMQ

    Your company has servers distributed around the world and you need to process data in a centralised location. The data is produced by applications using different technology stacks and comes from various sources, from web servers to sensors. How could you solve this problem? Enter RabbitMQ.

    In this talk we are going to show how to build a system that can ingest data produced at separate geo located areas (think AWS and it's many regions) and replicate it to a central cluster where it can be further processed and analysed.

    We will present an example of how to build a system like this one by using RabbitMQ Federation to replicate data across AWS Regions and RabbitMQ support for many protocols to produce/consume data.

    To help with scalability we are going to show an interesting way to implement sharded queues with RabbitMQ by using the Consistent Hash Exchange.

    If you want to learn what else has RabbitMQ to offer beyond simple messaging and queueing, then this is the talk for you.

    Talk objective:

    Our goal is to show that over the years RabbitMQ has gone way beyond a "simple" AMQP server to be able to have federated brokers, HA queues and support for many protocols and languages.

    Target Audience:

    • Developers interested in building a data ingestion platform that span many locations across the world.
    • Developers that have built these kind of solutions already but are interested in learning about alternatives.
    • Developers interested in RabbitMQ and Messaging in general.

    Alvaro Videla works as Developer Advocate for RabbitMQ/Pivotal. Before moving to Europe he used to work in Shanghai where he helped building one of Germany's biggest dating websites. He co-authored the book "RabbitMQ in Action" for Manning Publishing. Some of his open source projects can be found here: Apart from code related stuff he likes traveling with his wife, listening/playing music and reading books.

    The SCRUM and the willpower: how to boost your productivity

    Willpower is the force that is between the brain activity (I want to do this or I need to do this) and the action itself (start coding). If there is not enough willpower, people find it difficult to start any activity (especially that involves concentration an decision making). The willpower is not endless (so-called muscle theory of willpower), it can be saved, it can be trained, there are approaches how to keep the willpower level high. To keep the willpower (and thus, productivity) on the high level, people should know and use different approaches that lay in the field on the social and cognitive science. There are a lot of evidences that SCRUM improves the developer’s productivity in terms of speed of development, code quality, and accuracy of design. Unfortunately mainly all recommendations from SCRUM coaches look like “believe me, if you do this, you will have better velocity”. Yes, it works. But why does it work? Sometimes SCRUM does not give such great results even when main elements are in place. The question “Why” and “What makes the difference” is here again. I will describe the model of relationship between the willpower related brain metabolism on very low level (specific amino acid cycle) and the SCRUM practices. I can prove that SCRUM addresses the productivity of the people’s brain using 3 different flows simultaneously. There are several tips that make these productivity flows working or not. You can make Agile productive, you can have non-productive Agile. I will show you where the difference is. Overall there are 10 productivity tips that can be put into 3 flows. As the outcome of this session, Agile coaches, and all people who can change the process (in fact that is any team member) will review their SCRUM: does the way they have it improve the productivity or they are losing all the power? The changes are cheap, the outcome can be huge.

    Software Psychology: The Art of Listening to Code

    Writing code is fun, it's necessary, it's hard, and it's incredibly satisfying both as a hobby and a profession. But once your project gets too large to hold entirely in your head, its elegance and simplicity starts to deteriorate - and that's where software psychology comes in. When we listen to the code, and the design, and the devops, we can hear the code calling for help and it can lead us to the right place to refactor, to redesign, and to robust-ize. A simple case of listening is mapping defect rates to modules and then refactor the modules with the worst rates. A more challenging case of listening is when a complex multi-service architecture'd app suffers a performance brown-out: what do you listen for and how do you counsel the code through it's difficulties?

    I'll present a number of situations where listening to the code (or the design or the devops) is a good idea and various strategies (and tools) you can use to do so. I've got a wealth of examples from my years as a practicing software psychologist, so sit back and prepare to learn the art of listening.

    Programming, Only Better

    The programming paradigms that served us so well through the 80s and 90s are failing us. Building systems the way we're used to building them always seems to end in the inevitable death march towards exponential complexity. But once you stop to ask the right question- "what's really causing all this complexity?" - you realise the answers have really been staring you in the face all along. Debugging is only hard when you can't reason about your code. Concurrency is only hard when you can't predict the state of your code. Reusability is only hard when your components aren't naturally composable.

    Fortunately, languages addressing these issues specifically are popping up all over the place. In many cases, it turns out we've had the solutions to our problems for a long time, we've just forgotten about them, or never really bothered to look. Let's take a moment to explore some of these languages, not as exercises in syntactic details, but looking at the inherent properties in their design that enable us to defy decades of OO tradition and write honest-to-Dijkstra bug free, fault tolerant software without even trying. After half a century in the wilderness, functional programming seems to finally be gaining some ground on the barbarians. Let's examine why.

    Acknowledging CAP at the Root - in the Domain Model

    The techniques used to distribute software, scale it through concurrency or make it tolerant of latency are hobbled when, deep inside, the business logic is based on inappropriate assumptions of consistency. Yet it is common to do domain modeling and design business features heedless of these issues, and then patch things up after the fact with technical tricks. In DDD, we consider the the CAP tradeoffs to be central concerns of the design, and we incorporate into our domain models explicit assertions about the boundaries of consistency. When deployment reveals that additional or different CAP tradeoffs must be made, we go back to the root of the problem and modify the domain model to reflect those tradeoffs explicitly. In this talk, I’ll discuss three DDD patterns that help us address CAP tradeoffs: Aggregates, Domain Events and Bounded Contexts.

    WebRTC changes everything! For the first time, we can do peer-to-peer, or client-to-client, communication in the browser without plugins, extensions, or a software installation. This enables an entirely new class of applications to be built for the web! This talk will look at WebTorrent, a BitTorrent client for the browser that fully-interoperates with the regular BitTorrent network. WebTorrent uses WebRTC Data Channels and special "hybrid clients" to connect to the wider BitTorrent network.

    Continuous integration for Infrastructure

    Continuous integration is the practice of merging code from individual working copies with a shared mainline on every commit. It's main aim is to prevent integration problems from many people working on the same codebase and it is now common practices amongst high performing software teams.

    Continuous integration maps well to infrastructure practices too, where you generally have only one production infrastructure but many people working on it. But what does unit testing or integration testing mean in the context of infrastructure as code? And do other common software checks like linting, code coverage or static analysis have equivalents for infrastructure pipelines?

    This talk will explore what is possible when you treat your infrastructure as code, looking across Infrastructure as a Service, Platform as a Service and container based deployments to identify useful patterns and practices.

Furthermore, they must be reliable and robust in the face of constantly evolving system functionality. Achieving all of these goals requires close attention to the craftsmanship of our test code as well as finding the right vocabulary (and therefore abstraction level) for describing the functionality. Gerard will demonstrate how to apply these ideas to both unit tests and component or even system-level tests using a variety of test automation tools.

    Gerard Meszaros is an independent software development consultant and trainer with 30+ years experience in software and over a decade of experience in agile methods. He started doing eXtreme Programming in 2000 and quickly discovered that close attention to test craftsmanship was essential to keep the cost of change low. He described his key learnings in his book xUnit Test Patterns – Refactoring Test Code which was published in May 2007 by Addison Wesley in the Martin Fowler Signature Series and it won a Jolt Productivity Award in the Best Technical Book category. Since then he has turned his attention to applying the same concepts to organizing the automated acceptance tests as executable examples. He is based near Calgary Canada and has coached teams and taught courses as far afield as China, India and Europe.

    How I Learned to Stop Worrying and Love Flexible Scope

    Not fixing scope too far in the future is one of the cornerstones of agile delivery, but it is at the same time the thing that enterprise stakeholders fear the most. Ironically, being able to change decisions after delivery starts is one of the biggest benefits that companies can get from agile delivery, so it's necessary to stop worrying and embrace flexible scope to get the full benefits of an iterative process. In this talk, Gojko Adzic will show you how to convince people to embrace flexible scope, not only for startup environments but for big enterprise projects as well.

    Did you know that only about 60% of releases are delivered on time and only half of those are without critical bugs? Delivering quality software on time is an enormous challenge due to all the inherent complexities. There are multiple practices, tools and methodologies that promise improvement, but do they deliver?
    It is time to stop basing our decisions on anecdotes. We need a simple and solid model of software delivery and a measurement system that allows to test their validity. We started such a model and surveyed a 1000 organisations against it. We will show you quantified results on the improvements you can expect with particular tools and practices as well as discuss the model itself and how it can be applied in your environment.

Yet writing even more tests of the same kind quickly runs into diminishing returns. I'll talk about new automated techniques that can dramatically improve your testing, letting you focus on what your code should do, rather than which cases should be tested--with plenty of war stories from the likes of Ericsson, Klarna and Volvo Cars, to show how these new techniques really enable us to nail the hard stuff.

    Alice In Wonderland - Is the Network the Next Frontier for Devops? Devops and Networking

    Around 6 years ago I started working with some tools that focused on software engineering collaboration and automation for operations. At the time products like CFEngine and Puppet were the two main tools promoting this new way of doing operations and sharing within operations and software development. A year later Chef was born and I was fortunate enough to join Opscode as the 9th employee as an evangelist preaching this disruptive form of collaboration and automation. At the time a majority of IT infrastructure was managed by what I called the "Bob’s" of the world. Bob’s scripts, Bob’s directories and Bob to death do us part. Trying to explain to Bob the benefits of collaboration and software engineering principles was a hard fought battle over the years. One of the compelling events that helped propel these ideas (what we now call Devops) was cloud computing. Fast forward to 2013 and these infrastructure automation and collaboration battles still exist but the battles are far less bloody. Now a new war is emerging in the Network operations and engineering space. The same argument for network operations adopting these principles has always been the same as system ops; however, now the new compelling event is the virtualization of the network. Software Defined Networks is a lot of buzz, but the reality is that many network operations and engineering groups are dealing with an influx of highly virtualized tooling like OpenVswitch, Openflow, OpenDaylight and NSX. Configuration tools are starting to get more sophisticated on these virtualized systems doing things like automated VLAN to Port mapping and basic system hardening. Chef and Puppet both have introduced primitives supporting platforms like Arista, Juniper and Cumulus Networks. Help me start the discussion of what Devops and the Network really mean.

    Going Reactive: Event-Driven, Scalable, Resilient & Responsive Systems

    The demands and expectations for applications have changed dramatically in recent years. Applications today are deployed on a wide range of infrastructure; from mobile devices up to thousands of nodes running in the cloud—all powered by multi-core processors. They need to be rich and collaborative, have a real-time feel with millisecond response time and should never stop running. Additionally, modern applications are a mashup of external services that need to be consumed and composed to provide the features at hand.

    We are seeing a new type of applications emerging to address these new challenges—these are being called Reactive Applications. In this talk we will discuss four key traits of Reactive; Event-Driven, Scalable, Resilient and Responsive—how they impact application design, how they interact, their supporting technologies and techniques, how to think when designing and building them—all to make it easier for you and your team to Go Reactive.

    Complex Projects aren't planable but controllable

    Science has finally approved it: Forecasting complex projects is a deception. Moreover, forecasts hinder innovations. Daniel Kahneman, Nobel Prize Winner in Economic Sciences and psychologist verified in many cases, that forecasting of complex projects is impossible. Yet still, we keep losing time trying to do exactly that. Beyond Budgeting came empirically to the same findings and offers a concept for controlling corporations without budgets. Additionally Beyond Budgeting provides advice for controlling even long-term complex projects. Agile methodologies generally recommend developing a long-term plan on a coarse-grained level only and coming up with detailed short-term plans iteratively. In this talk I want to provide insights in the latest scientific research and show as well how Beyonddeudgeting and Agile principles can be combined so that even complex projects remain controllable.

    The art of building tools - A language engineering perspective

    Developing software often requires using a number of tools and languages. In embedded software, for example, it is common to use C and its IDE, Matlab/Simulink, a number of custom XML files, a requirements management tool such as DOORS and possibly a UML tool and a variant management tool. The integration of such a zoo of tools is often a major source of (accidental) complexity in development projects.

    Contrast that with the "good old days" when everything was text files and command line executables running on the unix shell. This approach had two important properties: the infrastructure was extremely generic (unix shell, pipes, text editors) and the actual contents were easily extensible and composable (new text file formats/languages and new command line tools); a productive environment for a given project or domain could easily be built from the generic infrastructure plus a few custom extensions.

    In this talk I want to propose that creating (domain-specific) development environments based on language workbenches results in many of the same advantages that we all valued in the unix shell-world. A language workbench is an extremely generic infrastructure that is easily extensible with new languages. It is easy to create domain-specific development tools that can address different aspects of the system with suitable abstractions, but are nonetheless very well integrated in terms of syntax, semantics and tooling.

    In the talk, I illustrate the approach with examples from two domains. One is mbeddr, an open source environment optimized for embedded software development. A second example is taken from the business/insurance domain.

    It's never too late to fight your legacy!

    Every frontend developer reaches the point where continuous feature development and rapid changes makes it hard to maintain a codebase in large scale, and the complexity starts to climb up to the sky. Instability and slower development is not an option for us, so we had to experiment with new methods and technologies. Unit testing was not a common technique on client-side in recent years, but over a certain amount of complexity it's essential.

    At Ustream we feel the need of full coverage including unit testing and end-to-end testing and bringing our structured framework into play with continuous integration on the frontend side.

    Delivering Continuous Delivery Continuously

    Over the last few years the Guardian has built up a set of tools (commercial and in house) that allows developers to build fully integrated continuous delivery pipelines in minutes rather than hours or even days. This reflects a change on the ground where developers have geared up to take on far more operational responsibility whilst operations have taken on a consultancy role to the developers.

    At the heart of this has been the creation of an in house deployment tool that streamlines what was previously a set of manual steps (with too many opportunities for humans to type “yes↵”) into a self service web application with an API and easy integration with the build system.

    This talk will go through the tools and processes that have been created to make continuous delivery easy and show that:
    • By providing tools that let developers deploy whilst keeping operations in the loop we reduce time to deploy, can deploy more frequently and allow operations to spend their time more usefully
    • By providing tools that are easy to chain together in different ways, users are able to experiment and try new things

    Simon Hildrew started out as a Java developer but was sucked into operations at a startup. Later on, after heading up the operations team at the Guardian for a couple of years, he hired someone else to do that and set about solving some of the challenges of an organisation with an ever increasing desire to adopt a devops culture. To that end he has spent the last two years working with both developers and operations in areas of monitoring, deployment and provisioning and created a handful of tools along the way.

    Exploiting Loopholes in CAP

    By now, we've all learned the summary version of CAP: choose at most two from "Consistency", "Availability", and "Partition-tolerance." It's usually framed as a binary choice between C and A, with P as the unavoidable reality. It turns out that the proof of CAP is very, very specific. We'll look at what it really says, and we will find loopholes big enough to drive a truck through. By exploring CAP at a deeper level, you will learn how to engineer practical, real-world systems with desirable features. After this talk, you will combine your theoretical understanding with your domain knowledge to make thoughtful choices in your distributed systems.

    Building on SOLID Foundations

    Why can’t we just add a feature to our system without tearing the code apart or, worse, patching around it? It ought to take just a few lines. We know the code is supposed to be modular and coherent, but too often it just doesn’t turn out that way.

    We don’t believe it should be this hard to change object-oriented systems. We’ve seen examples where it really is that easy to add a new feature. The difference seems to be in the intermediate level structure. The design principles that most programmers rely on don’t address the middle ground where the complexity lies. We know about principles and patterns at the small scale, such as SOLID, and the large scale, such as REST. We’re less familiar with the structures in the middle.

    This talk is about design principles that we’ve learned help us develop mid-scale code structures that are easy to read and easy to change. At the lowest level, this means well-known patterns such as avoiding globals and following SOLID guidelines. At larger scales, this means assembling those SOLID objects to avoid hidden coupling so that the system as a whole is amenable to change. We focus on how objects fit together and communicate, and on being clear about how capabilities and information flow between objects in the running system.

    Agility and the essence of software architecture

    On one hand the software development industry is pushing forward, reinventing the way that we build software, striving for agility and craftsmanship at every turn. On the other though, we're continually forgetting the good of the past and software teams are still failing on an alarmingly regular basis. Software architecture plays a pivotal role in the delivery of successful software yet it’s often neglected. Whether performed by one person or shared amongst the team, the software architecture role exists on even the most agile of teams yet the balance of up front and evolutionary thinking often reflects aspiration rather than reality. By steering away from big up front design and ivory tower architects, many teams now struggle to create a consistent, shared technical vision to work from. This can result in chaos, big balls of mud or software that still fails to meet its goals, despite continuous user involvement.

    This talk will explore the importance of software architecture and the consequences of not thinking about it, before introducing some lightweight techniques to bring the essence of software architecture back into an agile environment. We'll look at creating a shared vision within the development team, effectively communicating that vision and managing technical risk. I'll also share the strategies that I've used to introduce these techniques into agile teams, even those that didn't think that they needed them. Expect collaboration, sketching and plenty of gamestorming.

Names and irrelevant details have been changed to protect the somewhat innocent, but everything is based on actual things I had to experience – and sometimes helped create – in the real world.

    Babelsberg - Modularizing Constraint Satisfaction in Imperative Programs

    Constraints are relations between objects that we want to hold. This could be that all parts in an electrical circuit simulation obey the laws of physics, that the rows in a Sudoku add up to 9, or that a streamed video play smoothly in the presence of changing CPU or network load.

    Babelsberg presents an integration of constraint satisfaction with objects and their methods in Ruby and JavaScript, building on earlier work on constraint-imperative programming. In Babelsberg, constraints are assertions that the system tries to satisfy automatically. In my talk, I will discuss the motivations for creating a new language in general and for Babelsberg in particular, and present examples of how we applied Babelsberg to existing problems.

    Tim Felgentreff is a PhD student at the Hasso-Plattner-Institute, University of Potsdam.

    The State of Mobile HTML5

    "Mobile web is dead" - We have seen this sensational title on tech articles and blogs numerous times. And we, web developers have been trying to defend the web for past years without much success.

    In the beginning of last year, I showcased the capabilities of the Web platform and the real-life use cases of HTML5 in mobile by writing a camera application using W3C HTML5 standards and JavaScript. Although some of the obscure APIs may have surprised web developers how much HTML5 can do, the web app was still nowhere close to be perfect, or cross-browser compatible. Now, one year has passed since, and how have browsers been improved? New proposals? What are still missing, and what do we need to do to stop the obnoxious tech writes from writing the obituaries of HTML5?

    Erlang Patterns Matching Business Needs

    In this talk we will present a number of common patterns from Erlang systems and how these patterns relates to business needs.

    Most of the patterns revolve around the notion of how failure is handled and we will discuss how active treatment of failure leads to better options for the product owner when it comes to prioritising fixes and new features.

    By modelling the patterns using OPM (Object-Process Methodology) we get a new way of talking about Erlang systems and architectures, which will make our thoughts and insights easier to share.

    When dynamic becomes static: the next step in web caching techniques

    Tools like Varnish can improve scalability for static sites, but when user-specific content is needed, a hit to the backend is still needed, causing scalability issues. We'll look at a new Nginx module which implements a fast and scalable solution to this problem, changing the way developers think about designing sites with user-specific content. We'll go into how the module works and we'll put the old and new setups head-to-head to showcase the performance and scalability differences.

    Day 1 (Wednesday) — 9:00 - 17:00Accelerated Agile: from Months to Minutes

    Accelerated Agile: from Months to Minutes

    Great software professionals build better software faster. Agile methods, continuous delivery and software craftsmanship helped speed up delivery from years to months or even weeks, but then what?

    Some teams are able to deliver software at a speed of change like you have never seen before, delivering quality software in days or even hours, again and again. So what is keeping the rest of us from doing so? Now is the time to go from months to minutes, to rethink the way we organize and improve our software development and delivery process.

    Accelerated Agile is for people who believe it can be done. People who feel themselves limited by current Agile, CD and Craftsmanship thinking. People who want to go back to basics and uncover new, simpler ways to deliver great software. Are you a seasoned agile developer who is frustrated at how slow your “hyper-performing” process feels? Are you suffering with an unwieldy feature backlog, the pantomime of estimation, the card wall where cards go to die, the efforts to automate where it obviously isn’t adding anything? Are you fed up with the artificial commitment of sprints and the unwelcome surprises that still seem to derail your projects?

    Accelerated Agile brings agile principles into the 21st century. You will learn new techniques that both enhance and replace existing agile practices, some of which are counter-intuitive and many which are completely counter to current “agile” doctrine. Using a mixture of discussion, instruction and exploration you will start to think differently about design, architecture, development and testing, operations, automation and team dynamics, as well as working with legacy systems and integrating with third parties.

    What you will learn:
    • How to challenge the received wisdom of established Agile methods
    • How to design and architect for rapid and sustainable delivery
    • Why understanding risk and embracing uncertainty are at the heart of faster delivery
    • How to manage build, release and operations
    • How systems thinking can help you plan effectively and estimate accurately
    • How to identify and reduce gaps in your testing strategy
    • How to engage with legacy systems and integrating with third parties
    • How to manage different levels of skill and experience within a team

    Day 1 (Wednesday) — 9:00 - 17:00Impact Mapping: How to Make a Big Impact with Software Products and Projects

    Impact Mapping: How to Make a Big Impact with Software Products and Projects

    Impact Mapping is a strategic planning technique that prevents organisations from getting lost while building products and delivering projects, by clearly communicating assumptions, helping teams align their activities with overall business objectives and make better roadmap decisions. Impact mapping can help you build products and deliver projects that make an impact, not just ship software.

    The participants of this interactive workshop learn about the basics of Impact Mapping, and try it out in practice on several realistic examples to understand the key facilitation techniques and learn how to run and apply Impact Mapping sessions in their organisations.

    Key learning points:
    • how to create good user stories
    • how to ensure that you're building the right product
    • how to align the activities of delivery teams and the organisation around them
    • how to make an impact with software products and projects
    • how to communicate overall goals and vision to delivery teams
    • how to facilitate impact mapping sessions
    • how to build a delivery roadmap and backlog with impact maps

    Intended audience
    The workshop is aimed at product owners, business analysts, developers and testers working primarily in an agile or lean environment. It is based on Gojko Adzic's books Impact Mapping, Specification by Example and Bridging the Communication Gap. In order to attend the workshop, you should already have a basic knowledge of iterative delivery methods and a at least some experience of working in a Scrum, XP or Kanban-like delivery. To get the most out of this workshop, you should have a relatively senior role, from a technical or business perspective, in software delivery.

    Gojko Adzic is a strategic software delivery consultant who works with ambitious teams to improve the quality of their software products and processes. He specialises in agile and lean quality improvement, in particular agile testing, specification by example and behaviour driven development. Gojko is the author of the Impact Mapping book.

    Build a Single Page Application in Just One Day

    Most web technologies developed in the past had only one purpose: to offer the users a great experience, mimicking the one you normally get from desktop applications. One way of developing those kind of applications that emerged last year is Single Page Application where everything fits in more or less on one single web page. In this workshop we will develop a SPA from scratch using technologies like ASP.NET Web.Api, Breeze.js, Angular.js. The resulting application will be yours to take home and to continue work with it, and learn from it. For best experience I recommend that you bring your own device with Visual Studio 2012+ installed on it, although any text editor (vi included) will do.

    Before moving back to Romania in 2012, Tiberiu 'Tibi' Covaci lived with his family in Sweden and Bermuda for 16 years. In 2003 he founded Many-core, a company that trained and mentored developers and architects around the world to understand the .NET Framework and the technologies built on top of .NET. He works closely with Microsoft as member of the Developer Guidance Council, course Author, and Technology Reviewer for the Microsoft .NET Official Curriculum courses. He is a member of the ASP Insider and Telerik Insider groups, IASA Speaker & Trainer, INETA Speaker and Country Lead, founding member of IASA Sweden and IASA Romania, and former member of the MCT Advisory Council.
