[SLIDES]Uncle Bob / Robert Martin @unclebobmartin - The Last Programming Language

Rate the session!

For the last 50 years we’ve been exploring language after language. Now many of the “new” languages are actually quite old. The latest fad is “functional programming” which got it’s roots back in the 50s.
Have we come full circle? Have we explored all the different kinds of languages? Is it time for us to finally decide on a single language for all software development? In this talk Uncle Bob walks through some of the history of programming languages, and then prognosticates on the future of languages.

(NEKALBEJO)Paul Stack @stack72 - Creating a scalable, repeatable infrastructure with Terraform

Rate the session!

The age old task of racking and stacking in a physical data centre is
becoming more and more rare as more companies embrace the public
cloud. Having the ability to choose between providers such as AWS,
Azure, Digital Ocean and Google Cloud Platform makes creating
infrastructure easy. It is better to spend time developing better
services for our customers than managing infrastructure

During this talk, Paul will demonstrate how building a scalable
infrastructure on AWS becomes easy with Terraform. The talk will
demonstrate how using configuration management, pre-baked AMIs and
auto-scaling groups it gives the ability for developers to be able to
launch their own infrastructure when needed. The demo’s will include
the ability to launch instances, databases and manage user access

By the end of the talk, Paul will have demonstrated that the creation
of infrastructure now becomes part of the development lifecycle and
that the old ways of system administration is fast moving to become
infrastructure engineering. Paul will also demonstrate that the
creation of new ‘environments’ are just a change of parameters in our
infrastructure code

(SLIDES) Dmytro Mindra @dmytromindra - Refactoring Legacy Code

Rate the session!

Every programmer has to face legacy code day after day. It might be ugly, it might look scary, it can make a grown man cry. Some will throw it away and try rewriting everything from scratch. Most of them will fail.

Refactoring legacy code is a much better idea. It is not so scary when you take it in very small bites, introduce small changes, add unit tests. When code is refactored and unit tests are added, changes to functinality can be introduced.

We will take an open source c# project and will refactor it showing step-by-step examples of the techniques.

This session is full of tips and tricks you can start applying immediately. Although the code is in C#, the same principles can be applied in any language

(SLIDES) Jeremy Gibbons @jer_gib - Categories for the Working Programmer

Rate the session!

The Haskell community is famous - perhaps infamous - for its enthusiasm for category theory. Why is this? Is it important to understand categories before you can understand Haskell programs? Is it an attempt to keep the community as pure as the language? Is it just that Haskell is a refuge for underemployed mathematicians? None of the above!

In this talk, I hope to explain a little bit about how categories can help the working functional programmer. I'll focus on categories as an organising principle, helping us to manage generic libraries. No monads were harmed during the making of this talk.

(SLIDES) Nakul Mishra - Microservice - no fluff the REAL stuff

Rate the session!

Some developers tend to believe that big data and huge traffics are pre-requisites to harness and reap the benefits offered by microservices. However, there are many problems like polyglot persistence, faster continuous build cycle, shorter release plan, etc. that can be solved by applying microservice architecture even in smaller organizations. You don't have to be a software giant to leverage stability, effectiveness and flexibility provided by microservices. Microservice architecture has a lot to offer even for smaller organizations. In this talk, we will walk through the key concepts like service discovery & registry, circuit breaker, API gateway and edge service. Build a bunch of microservices demonstrating practical implementation of these patterns using open source components like Eureka, Zuul, Hystrix and powered by spring cloud. Lastly, we will deploy our microservices on a container based solution, i.e. Docker and discuss how tools like Chaos Monkey and Janitor Monkey can help making our application fault-tolerance and keeping the cloud's infrastructure neat and tidy.

(SLIDES) Ali Kheyrollahi @aliostad - 5 Anti-Patterns in designing APIs

Rate the session!

This talks elaborates on the Client-Server tenet of REST which focuses on separation of concerns between the client and the server. In the first third of the talk, I will talk about what the ideal client and servers are and examples of how their responsibilities. I will touch on how the word Server has lost its meaning of "serving" and the client has been overshadowed by the focus to the API. I will also compare the API to a restaurant and how its menu is the API's REST resources.

In the rest of the talk, I look at some important anti-patterns commonly seen in the industry (each with at least one example):

1) Chauvinist Server: designing the API from server's perspective failing to hide its complexity behind its API (API designed from the server's perspective)
2) Demanding client: client enforcing its special need onto the signature of the API (certain client's limitation becomes server's default behaviour)
3) Transparent Server: server exposing its internal implementation to its clients (server's underlying or private domain bleeds into the public API)
4) Presumptuous Client: The client assuming the role of a server and engage in taking responsibilities that cannot guarantee
5) Assuming Server: Server that assumes the responsibility of tailoring the response based on what it assumes client is (e.g. browser sniffing)

(SLIDES) Jef Claes @JefClaes - Evil by Design

Rate the session!

In this talk, I'll share what my experience has been working in the gambling business, how moving to events helped us gain a better understanding of the domain and which techniques and models casinos have perfected over the years to keep people playing.

---

Last year I ventured into the domain of (online) gambling. Given that the industry has been around since forever, I expected most problems to be of the technical kind. As it turned out, the struggle with technology was only part of a bigger problem; to move forward we needed to fully grasp the industry and its consumers.

Domain events started out as a way to dismantle a legacy system, but quickly proved to be an effective tool to gain a deeper understanding of our domain. Visualizing event streams, we discovered patterns that helped us identify what drives different types of users.

Having a better understanding of what customers are looking for, we dove into existing literature to learn which techniques and models casinos use to cater for each type of user. We learned how to program chance while staying true to the Random Number God. Even when variance is brutal, casinos have enough data and tools to steer clear from the pain barrier.

All of this entails interesting problems and software, but isn't my code damaging society? Or is gambling just another human trait?

Rate the session!

At a certain point software was everything in my life. Learning new languages, architectures, design patterns and acquiring skill in practice - my raisons d'etre. After a while things clicked, and I started leading teams of more junior programmers.

"The People Problem" presented new and foreign challenges. There's nothing quite like working with others on real products to transform egocentric practice into empathic pragmatism. My search for a new bag of tricks led me back to my earlier studies in the humanities. Suddenly my liberal arts education, formerly regarded as tangential even if interesting, felt applicable to more than cocktail party conversation.

In this talk we'll look at disciplines outside the purview of software development with an eye for how borrowed ideas can yield not only inspiration and analogy, but real innovations and breakthroughs. I'll share examples from fine art, psychology, history and literature influence my approach and the work of others.

My sincere hope is that you'll walk away from our time together with a heightened appreciation for how looking outside software development can enhance your journey within software development.

Rate the session!

This tutorial will look at the problem of implementing languages in Erlang on top of the Erlang system. Such languages can be anything from small DSL for coding a specific problem to a complete language which for some reason it is beneficial to run it natively inside Erlang. We will look at parsing languages, implementing a basic interpreter and then integrating that into an Erlang application. Finally we will discuss compiling our languages into Erlang. As an example we will use a small existing language. The topics we will look at here are quite common and apply to most languages and many of the solutions are also applicable to othere langauages and systems apart from Erlang.

Rate the session!

Microservices are in, monolithic apps are out, everyone is high in the cloud, SOA is undead, ReSTful is never really ReSTful because pragmatism, and messaging is either really awesome or really bad. Very complicated, right? Complex systems are all around us, often made of many small and simple entities. In this talk we'll explore how complexity can be reduced to its smallest cohesive parts, communication normalized through the power of evolvable contracts, ReSTful and event-driven interfaces, and how to make a microservice swarm fly in unison.

KEYNOTE: Mel Conway @conways_law - Coding vs. the Brain: Can't We All Just Get Along?

Rate the session!

In an extremely short time interactive information appliances such as mobile devices, computers, and interactive kiosks such as ATMs have exploded into common use all over the globe. An understanding of how these appliances work must now join arithmetic and the calendar in the migration toward universally accessible simplicity. This migration will require a radical simplification of the conceptual model for the internal workings of interactive appliances that is more intuitive than algorithms for the mass of people.

The talk presents a hybrid unidirectional-flow/message model of the internal operation of interactive information appliances that is intuitive, generally applicable, and largely algorithm-free. It also presents design principles that formalize what-you-see-is-what-you-get construction-tool behavior. Finally, the talk demonstrates a proof-of-concept application builder that conforms to these design principles and that builds small applications that work according to the new conceptual model.

Normal people might have squabbled or shrugged, but not us nerds! We obviously abandoned the game, took our laptops to the local pub and started hacking. In this talk I will explain how I used F# to transform this problem to satisfiability, and ran it through a sat solver to discover if it can indeed end in a tie.

I will also show how to apply the same technique to more useful problems such as scheduling and register allocation.

One of the reasons for this is the vast array of choice they have in how they run their applications in the cloud. One choice customers have to run their applications, that is not so well known, is to use Unikernels. At the end of the talk, you will understand how Unikernels can make your applications efficient, scalable and secure.

The talk will be followed by a demonstration on how we all can take advantage of unikernels right now. An existing Linux-runnable web service will be converted to a unikernel and executed both the local desktop and on Amazon EC2.

Most modern programming languages have taken inspiration from the functional programming paradigm and have implemented features for making functional modelling easier. To be able to fully leverage the power of languages such as C#, it is therefore necessary to have an understanding of functional programming as well as other paradigms such as object orientation. This presentation gives an introduction to Haskell and compares it to the features provided in C# that have been influenced by concepts from the functional world. In particular, it aims to illustrate how a functional approach to solving problems differs from an object oriented approach.

Test-Driven Development is about writing a test first, then the code that satisfies the test. Or... is it?
Classic TDD has been crucial in my growth as a developer; and yet, as I started using F# more and C# less, my coding practices have evolved dramatically. Nowadays, I barely test first, but spend my days in the scripting environment. In this talk, I will examine how I write code in F# today, in a style I consider very much inspired by TDD; I will also discuss how exploring two paradigms (C# and F#) forced me to re-examine my beliefs, and evolve a slightly different (and perhaps less language specific) understanding of some of the same core principles.

Rate the session!

Over time, almost all large, well-known web sites have evolved their architectures from an early monolithic application to a loosely-coupled ecosystem of polyglot microservices. While first-order goals are almost always driven by the needs of scalability and velocity, this evolution also produces second-order effects on the organization as well. This session will discuss modern service architectures at scale, using specific examples from both Google and eBay.

It will cover some interesting -- and perhaps nonintuitive -- lessons learned in building and operating these sites. It continues with some more advanced implications of a microservices architecture, including SLAs, cost-allocation, and vendor-customer relationships within the organization. It concludes by exploring a set of common service anti-patterns.

(SLIDES) Dylan Beattie @dylanbeattie - Domain Architecture Isomorphism: How Spotlight Inverted Conway's Law

Rate the session!

Conway's Law says that "organizations which design systems ... are constrained to produce designs which are copies of the communication structures of these organizations". We've seen this happen time and time again. Some organisations are fortunate enough that their communication structure happens to match their ideal architecture. Some organisations succeed in spite of their communication structures, but all too often the communication overheads result in systems that are delivered late, over budget and unfit for purpose.

But what if we're looking at it backwards? Maybe we should start with the system design, and then create an organisational structures that reflects it?

Dylan is the systems architect at Spotlight (www.spotlight.com), the UK's leading casting service. Since 1927, Spotlight has been used to cast productions from Monty Python and James Bond to Star Wars and Game of Thrones. Originally a printed directory, Spotlight has been on the web since 1996, and was one of the first companies in the UK to embrace digital publishing. Having successfully made the transition from a paper-based directory publisher to a digital services company, we now find ourselves in the unusual position of being nearly a century old, yet facing many of the same problems as a successful startup. In this session, we'll talk about how we're restructuring Spotlight so that our systems and our structure align with the natural domain boundaries of our business. We'll talk about the challenges we've faced - how do you promote microservices and modular architecture when some of your customers still think fax machines are a pretty neat idea? How can you decouple monolithic legacy systems, identify bottlenecks, and create just the right amount of architecture? We'll talk about systems integration patterns, and how to run the New Shiny alongside your legacy systems to avoid the risk of "big bang" launches. And you never know - we might even throw in a couple of good showbusiness stories.

(SLIDES) Brian Troutwine @bltroutwine - Getting Uphill on a Candle: Crushed Spines, Detached Retinas and One Small Step

Rate the session!

Looking back through history, we often view NASA’s early mission in terms of “getting to the Moon”, discussing how this or that program served the purpose of answering Kennedy’s challenge. This is wrong-headed. In this talk I will discuss aeronautics research beginning with the Writght Brothers and ending with the first Shuttle launch in 1981. We’ll see how NASA is an organization whose primary mission is basic research and development in aeronautics for the benefit of the public at large and space exploration. We’ll see how the Lunar Program was a focusing of research to a practical, political aim which built off decades of basic research and necessarily side-lined other programs. It’s my aim to convince you that Moonshot projects cannot be considered independently of their organizations and its history.

(SLIDES) Osvaldas Grigas @ogrigas - Life without Objects

Rate the session!

Transitioning from OOP to functional style can be quite challenging, not least because OO programmers are used to thinking in nouns. Programming languages that use functions as primary means of abstraction force one to:

- design things in terms of verbs,
- find new ways of doing composition,
- rediscover polymorphism in a different light.

Fear not! What you have learned about good OO design can be applied to FP, in obvious and weird ways. Code examples will be presented in Clojure.

(NENAUDOJA)Venkat Subramaniam @venkat_s - Let's Get Lazy

Rate the session!

How can big data or highly responsive applications scale to the increasing demands for speed and short response time? Adding more servers to the cluster is not the answer. The smartness comes from being lazy as laziness can translate to efficiency and scalability. In this presentation we will learn about what lazy evaluation is, explore some data structures and APIs that promote lazy execution, and tie it back into scalability and efficiency.

CIDER is the most popular programming environment in the world of Clojure these days and it's quite unique, for it's not a plugin for IntelliJ, Visual Studio or Netbeans; quite the contrary - it's built on top of the Emacs editor and it still provides a ton of cool features that most IDE users have come to love and expect from a modern programming environment.

We'll discuss whether (why) it's a good idea to build dev tools on top of Emacs, the history of the project, its current state and the bold plans for its future.

Be advised - by the end of the talk you'll probably become an Emacs user for life, so attend it at your own risk! :-)

I first attended one of Greg's workshops on CQRS and message driven architectures several years ago and fell in love with the design patterns. However what seems so clear to me seems to often elude even senior developers who I try to introduce it to. The key element I've found in getting developers to write code using the new patterns is to get them thinking in the new patterns. Solving problems in the new way, rather than what they have always done. I'll be talking about the problems I've seen on different teams moving from a training context to solving problems in production code under a deadline. Then we'll cover some of the key mental blocks to adopting the new methodologies. Finally walking through successful approaches that have gotten people thinking and solving problems in the new ways.

Amanda Laucher @pandamonial - Property Based Testing: Shrinking the Risk in Your Code

Rate the session!

Perhaps you’ve been hearing a lot about Haskell programmers being absolutely certain that their code is correct but you haven’t taken the leap into day to day Haskell development. Do not despair, there are techniques that can allow you to have confidence in your code without needing to change your development stack. In fact, you can use the same testing techniques Haskellers use without even using a language with a static type checker.

In this session we will be looking at Property Based Testing, and how this approach can allow us to avoid thousands of lines of testing code when ensuring that our code meets specification. Property Based Testing generates inputs based on the properties of the program that we stipulate, and so are based on the business logic, in the same way that types are. Furthermore, if the test fails, a good framework will shrink the problem to the smallest possible data set that gives an error, helping to pinpoint the bug. This session requires no previous knowledge of free-monads, co-products, or other terms you may have grown to hate.

Mathias Brandewinder @brandewinder - Crunching through big data with MBrace, Azure and F#

Rate the session!

For data exploration and rapid prototyping, the productivity of an interactive scripting environment is hard to beat: simply grab data, run code, and iterate based on immediate feedback. However, that story starts to break down when the data you have to process is big, or the computations expensive. Your local machine becomes the bottleneck, and you are left with a slow and unresponsive environment.
In this talk, we will introduce MBrace.net, an open-source and free engine for scalable cloud programming. Using the MBrace programming model, you can keep working in your beloved familiar scripting environment, and easily execute C# or F# code on a cluster of machines on Azure. We will focus primarily on live demos, from provisioning an Azure cluster with Brisk, to analyzing large datasets in a distributed fashion; in particular, we will discuss how this setup is relevant to data science and machine learning.

And still, we keep them dumb with a set of simplest heuristics when it's about monitoring complex infrastructures, leaving the largest part of the job - issue recognition and analysis - to ourselves.

Rate the session!

These days testing is considered a sexy topic for programmers. Who'd have thought it? But what makes for good unit tests (GUTs)? There's more to effective unit testing than just knowing the assertion syntax of a framework.

Testing represents a form of communication and, as such, it offers multiple levels and forms of feedback, not just basic defect detection. Effective unit testing requires an understanding of what forms of feedback and communication are offered by tests, and what styles encourage or discourage such qualities.

What style of test partitioning is most common, and yet scales poorly and is ineffective at properly expressing the behaviour of a class or component? What styles, tricks and tips can be used to make tests more specification-like and can scale as the codebase grows?

"The Turing Test will be passed by 2020. Not by an advanced artificial intelligence, but by a human being who is stupider than their own phone"

Did you read about the man who drove his car into a lake because Google Maps told him to? Or the woman who put her phone into "airplane mode" and threw it out of a window? Does Google ever freak you out by showing you stuff it's not supposed to know about?

Software and smart devices are changing the world beyond recognition, and all too often, the human beings who create it are struggling to keep up. We create devices that can make crystal-clear hi-def video calls to anywhere in the world, and then laugh at someone who microwaves their iPhone because they read online that it would charge the battery. You spend $800 on a tablet computer that doesn't even include an instruction manual - and then your three-year-old kid finds a shortcut for playing Peppa Pig videos that you didn't know existed. At the other end of the scale, we're building huge distributed systems too complicated for any human to understand. Decisions that affect our lives - the pages that show up in our search results; the people we meet on Tinder; the price we pay for car insurance - are being delegated to algorithms so sophisticated that nobody can explain why a particular result happened, or predict whether it will happen again.

So what can we do about it? As developers, how do we build systems that don't make people feel stupid? How do we empower users to make decisions and apply common sense in a world where tomorrow's technology is indistinguishable from yesterday's magic?

In this session, we'll talk about auto-correct, waterproof smart phones, cognitive bias, Markov chains, Windows 10, self-driving cars, chaos theory, the psychology of risk, Monty Hall, user experience design, the Dunning-Kruger effect, and why Facebook is still showing you adverts for cheap flights to Lithuania even though you're already here.

(SLIDES) Jonathan Graham @graham_jp - Reactive Systems: From Drug Development to Functional Programming

Rate the session!

Systems built as Reactive Systems are more flexible, loosely-coupled and scalable. This makes them easier to develop and amenable to change. They are significantly more tolerant of failure and when failure does occur they meet it with elegance rather than disaster.1

The approach to the design and development of manufacturing processes for the production of new drugs within the pharmaceutical industry has changed dramatically over the last decade. Focus is given to designing systems that are responsive to issues and constraints, through knowledge of the impact of exceeding standard operating ranges and the use of real-time analytics; resilient to failures that could occur at any point within the system; elastic to changing demands that occur during the lifecycle of manufacture through a flexible and well understood approach to scalability; and message driven, whereby the resources used and specifications required for a specific segment of the system are derived by the demands external to that segment. With Quality by Design2 applied throughout the development process, the industry is now beginning to reap the benefits from the flexibility that Reactive Systems provide in production.

In this presentation we will use learning’s from the Pharmaceutical Industry to explore the extent of the Reactive Manifesto for software development, and we will look specifically at how this relates to functional programming. The public demands high and consistent quality from the medicines that we take, and we should demand that same quality from the software that we develop. If you are passionate about the quality of your code, then this talk will provide you with a new perspective on how you think about your craft.
