I’ll talk about scalability and fault tolerance features of distributed Erlang. In particular, what makes it so good for large scale distributed applications on commodity hardware, where devices are inherently non-reliable and can disappear and re-appear at any moment.
The talk is based on experience of leading research on developing Scalable Distributed Erlang (SD Erlang -- a small extension of Erlang for distributed scalability) and integrating Erlang in robotics. So, I’ll share rationale behind design decisions for SD Erlang, lessons learned, advantages, limitations, and plans for the further development. And talk about benefits of Erlang in distributed robotics, initial findings, and plans.

Since it's introduction to the world at WWDC 2013 - Swift has rocketed in popularity - becoming the most popular language on Github in 2015. Both the language and the roadmap have now been open-sourced - and no longer limited to Apple's platforms - meaning it's now available on everything from Raspberry Pi's to the server. In this session - we'll build an API using Swift, then deploy and run it on the server. We'll also cover how you'd run this in Production, the integration options which are currently available and the roadmap for Swift 3.0 - so that you're aware of what's coming in the pipeline.
It‘s not the case anymore, that a good start-up needs an idea and an app. In pursue of success today we need more ingredients and new business processes. During this presentation you will hear examples and recommendations, on how to build a successful start-up: business process + idea + app.

Distributed Cluster Schedulers are becoming increasingly popular. They present a good abstraction for running workloads at a “warehouse-scale” on the public and private clouds by decoupling workload from compute, network and storage resources.
In this talk, we will talk about the operational challenges of running a Cluster Scheduler to serve highly available services across multiple geographies and in a heterogeneous runtime environment. We will go into details of the needs from a cluster scheduler with respect to managing multiple runtime/virtualization platforms, provide observability, running maintenance on hardware and software, etc.
The audience is going to be introduced to Nomad, a globally aware, distributed scheduler designed to handle any type of workload on any operating system. We will talk how Nomad solves the problems described above

Kotlin is a fairly easy language to grasp given its similarity with other mainstream ones such as Java, C# and JavaScript. However, Kotlin provides a few characteristics which makes it possible to write nice DSL’s. But the question is, do we always need full-blown domain specific languages in our applications? Are we really going to write all our business rules in a specific language?
Not necessarily, but that doesn’t mean we should discard DSL’s. In fact, DSL’s are really powerful when they are small and focused. In this talk we’re going to show a few DSL’s that we can create to deal with different aspects of our application, whether it’s business dealing with tax rules or infrastructure and working with transactions, and see how with very little effort we can create more concise, maintainable and readable code.

‘Zero defects’ is finally the new ambition of the SDLC IT. The Digital world is pushing us more and more towards the Holy Grail is software quality. In the last few decades the IT industry has looked at zero defects as a pain in the ass. New techniques and frameworks have put pressure on quality of software development therefore, enabling higher quality of work. But how brand new is this? Is this really the newest evolution or are we reinventing the wheel again?
In this talk Ewald will take us through the new reality of zero defects software development processes and revisit sometimes, prehistoric ideas from the past. Going back to the 60’s and 70’s to look at the software development processes where we had one engineer doing everything. Then we go back to early this milenium where there was a specific split between all disciplines in the SDLC and managers, developers, and testers looked to be on different sides on the SDLC.
Back to the current age and look how we now try to implement zero defects software and the new high performance teams where the team consits only out of DevOps engineers and also provide in-depth quality checks across the software cycle, supporting ongoing business resilience and reducing the cost of quality through optimized an optimized SDLC by detecting bugs before applications go live. Going back at the 60’s and 70’s and shifting left to focus on end-to-end quality early in the lifecycleIn the end learning from the past and implementing to move from ‘zero defects’ to ‘first time right’!

Architecture isn't just the static "shape" of your software. It's the set of decisions that define it, enabling — or inhibiting — change, evolution and improvement over time.
It is also the decisions about how you verify, deploy, version, manage and monitor an application. Each of these decisions is a trade-off: there are no Best Practises. Some decisions can have a huge forward impact, and it isn't always obvious which ones! In this talk Dan offers several strategies to help you improve your architecture decision-making.

Before the turn of the century, much ado was made about CASE (Computer Aided Software Engineering) tools and how they would simplify the process of delivering solutions. With the advent of Agile development processes, CASE tools were eschewed as being associated with BDUF. CASE Tools, including UML and E-R Designers, were relegated to the halls of academia and for illustrations in books on design patterns. Along with eschewing the tools of waterfall development, the industry also forgot some of the lessons learned by waterfall practitioners regarding good object modeling.

When we talk about automation in software development, we immediately think of automated builds and deployments. We may also be using scripts to help make our daily work easier. But this is really just the beginning of the rise of the machines. I show you how leading developers in our industry are using open source and commercial tools for automating much more. They've got "robots" for monitoring production servers, updating issues, supporting customers, reviewing code, setting up laptops, doing development reporting, conducting customer feedback -- even automating daily standups. In what instances is it useful to automate? In what cases does it not make sense? Automation prevents us from having to do the same thing twice, helps us to work better together, reduces workflow errors and frees up time to write production code. Plus, as it turns out, spending time on automation is fun! Don't be afraid of robots in software development, embrace them!

In 1991 Erik Meijer, Maarten Fokkinga, and Ross Paterson published "Functional Programming with Bananas, Lenses, Envelopes and Barbed Wire." This paper is a classic one, widely recognizable in the FP community. Constructs described - known as recursion schemas - have real world applications. Strictly speaking, explicit recursion is the ‘goto’ of pure functional programming. Recursion schemas provide same level of sanity as loops did for structural programming back in the day.Over the years a lot of the progress have been made. Papers like "Recursion schemes from comonads" by Tarmo Uustalu, Varmo Vene & Alberto Pardo or "Unifying Structured Recursion Schemes" by Ralf Hinze, Nicolas Wu & Jeremy Gibbons - pushed the concept forward.This talk is about generalization of a very specific recursion schema (called catamorphism) over fixed point data type. After providing introduction the concept of catamorphism, we will jump straight to fix point data types trying to solve some real-world problems. Code examples are in Scala. Code examples use Matryoshka - which is an open sourced project design to generalize folds, unfolds, and traversals for fixed point data structures in Scala.

If you've played games or worked in any one of a number of popular programming languages you're likely to have relied on a software machine written by a small but dedicated team of virtual machine enthusiasts. And unless you've taken a course in programming language implementation you probably have only a loose idea of what software machines are, how they work, or how easy it is to write your own. My interest in this field was sparked during the era of home micros when I chanced upon an article in a programming magazine on how to implement Forth in Basic. That article with its inscrutable magic became an obsession that lead to a career in coding and much else beyond. In this fast-paced introduction I'll use code written in C and Go to explain the basic building-blocks with which we can model computing machines in software, covering as many of the main architectural features as possible in the time: stacks; heaps; dispatchers; clocks; registers; instruction sets. I've rated the session as intermediate because it has a lot of code (and some mildly gnarly C), but if you're a beginner who wants to see a little of the magic underneath the tools you use, I'll hopefully have you covered to.

Docker started small and got big in really short time. Believe it or not, you can learn to build your version of it too, within the duration of a conference talk! In the talk, we will assemble and run a Docker-like container with only standard command-line tools found in modern Linux distributions. First half of the presentation will cover the facilities Linux provides for Docker to build upon: cgroups, pid and network namespaces, overlay file systems. During the second half we will put theory to practice in a terminal session. At the end of the talk we will not only be armed with knowledge how to build an isolated container, but also have an actual container running. After the talk, you will have a good insight how Docker works, and understand how you could use its building blocks to build something that perfectly matches your environment. You’ll get most out of this session if you are comfortable in Linux terminal, for instance, configuring networking from command-line. Knowledge about Pid namespaces, cgroups or overlay filesystems is not required. You will learn it all that during the talk.

When we talk about scaling, we usually mean up (bigger machine) or out (more machines). However, there is another alternative, which is changing our workload in a way that makes it inherently more parallelizable and then taking advantage of specialized hardware that's very good at handling that sort of thing. Most of us have exactly this type of hardware just sitting in our computers, doing very little most of the time. I'm talking, of course, about the GPU. General-purpose computing on the GPU (GPGPU) is no longer the domain of pure academic research. It is being used in real-world applications such as image processing and face recognition, cryptography, big data analysis, and Bitcoin mining. In this session we will examine the available GPGPU frameworks, learn how to integrate C++ AMP and OpenCL into regular .NET and Java applications, how to debug mixed .NET and GPGPU code in Visual Studio, and how to use the Aparapi framework to seamlessly mix regular CPU and GPGPU code in Java. We’ll even look at using GPGPU from server and client-side JavaScript with WebCL. We will discuss the kinds of tasks that can benefit from graphics card processing, how best to parallelize workloads, and what some of the performance trade-offs are.

Functional C++? As opposed to what — dysfunctional? Well, kind of, yeah. Sure, in C++ the principal unit of composition is called a function, but that doesn't mean it's a functional language. And the idea of restricting mutability of state gets a nod with const, but it's a nod not a hug. And the STL shows influences of functional programming, although it falls short of being compositional. And, yes, sure, C++11 introduced lambdas, but then again, these days, which language hasn't? Lambda calculus was invented in the 1930s.
This talk looks at how to express functional programming ideas in (post)modern C++ in a way that can be considered idiomatic to C++, rather than trying to use the power of overloading and meta-programming to pretend C++ is Haskell or Lisp. In short, immutability beyond const and into shared and persistent data structures, concurrency beyond threading and locks, and thinking about functions as transformations and units of composition rather than actions.

2. Beta
Service discovery and configuration has been an operational issue since Service Oriented Architecture became popular. With the advent of Microservices the problem has become even more acute. Previous solutions included technologies such as UDDI and load balancing, but this presented issues with scaling. Consul from HashiCorp claims to make this easy, but what technologies and principals did they use to build Consul that allow them to make that claim? In this session I will examine the 2 of the main pieces of research used to underpin Consul, the SWIM and RAFT protocols, and how they tackle the problems suffered by more traditional solutions, and also discuss how some design decisions in Consul make it far easier to integrate unobtrusively than previous technologies.

3. Run Stuff
Most of us are familiar with the architectural style known as REST, but even experienced developers often find it difficult to translate REST's architectural principles into running code. In this talk, we'll explore the elements of REST related to hypermedia and the principle of "hypermedia as the engine of application state" (HATEOAS) - we'll talk about why they matter, and when you might want to implement them in your own systems. We'll look at some of the tools that exist to help you design, deliver and debug your HTTP APIs, and we'll do some hands-on coding to show you how to implement lightweight, flexibile hypermedia patterns in your .NET web applications using the NancyFX HTTP framework and the HAL hypermedia application language.

Traditionally we consider web sites to be working in an online mode only. If the Internet connection drops, the entire web site stops functioning. Mobile applications, however, change this perception as connection is considered unstable and applications should take necessary measures for good user experience. Now we are able to create web sites that react on changes in the Internet connection and provide certain functionality offline. AppCache, IndexedDB and File API are few of the mechanisms to allow us to store the application and its data in the browser. However, now we have some questions to think about: Who is the master of the data - the client or the server? What data should we download in advance? How do we handle updates of the application? In this talk I will give overview of how web applications can go offline and which precautions we should take.
