[SLIDES]Natalia Chechina @nchechina - Scaling robots and other stuff with Erlang

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.

Diptanu Gon Choudhury @diptanu - Scaling Web Operations with Distributed Cluster Schedulers on Elastic Infrastructure

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

[SLIDES]Ian Cooper @ICooper - RPC is Evil

As the microservice train thunders into town, it is bringing with it an old enemy - the Remote Procedure Call. Libraries like Thrift are being used for client-server communication and no one seems to be looking back to the past to understand why we ran screaming from RPC last time. Drawing on bitter experience of DCOM, .NET remoting and Web Services, and his very British desire for a decent cup of tea, in this talk Ian Cooper will explain the anti-patterns of RPC and look at the alternatives which will ensure your system stays stable and he gets a decent brew.

Traditionally logging has fallen into one of three camps: don't do it, use an SaaS provider such as Splunk, or expend large amounts of time and energy configuring on-premise logging stacks. The maturity of cloud platform service offerings now means that you can have the flexibility of running your own logging stack without the headache and costs of managing individual components.
In this talk, Paul will demonstrate how the use of managed services like ElasticSearch, AWS Kinesis, and various log-shipping agents can build a scalable, easy-to-manage and cheap-to-run logging infrastructure that will ultimately save your company $$$.

[SLIDES]Tautvilas Mečinskas @tautviIas - The nature of programming

Computer programs are all around us, we interact with them every day. It looks as if software is becoming more and more important to our society. But why do we find programs so necessary to us? Why and when did we start programming? What is the essence of programming? These questions might sound trivial, but I feel that today we still don’t have a good definition of what programming is.

In this philosophical talk I will redefine the art of programming in a refreshing way. I will give the audience a new perspective about their daily jobs and some original insights about the nature of programming. After the presentation you will understand what programs, maps and clocks have in common and what is the ultimate purpose of software development.

[SLIDES]Hadi Hariri @hhariri - Creating DSL's in idiomatic Kotlin

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.

[SLIDES]Ewald Roodenrijs @ewaldroodenrijs - Zero defects, zero progress?

‘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’!

Windows has a reputation for being harder than it needs to be to run at scale.
This isn't as true as it once was.
This talk is about how one Windows platform went from being deployed a few times a year, to hundreds a year. Falling over at 2 orders a minute, to laughing at 2k/min. Monitoring by remoting onto machines into perfmon, to automated alerts from a central authority. Chewing days of engineering time on debugging machines to keep them limping onward, to gleefully shooting machines in the head on stage knowing the fresh ones would come back inside 20 minutes.

[SLIDES]Jezen Thomas @jezenthomas - Haskell On Rails

For years, Ruby on Rails has been the web application framework of choice for software developers who need to *Get Things Done*. We can rapidly prototype, and then effortlessly ship. But what happens when the complexity of the system inevitably grows? We write tests, and more tests, and even more tests, and still we're on our knees, fighting fires and debugging. We need better tools. We need our machines to automatically verify the fundamental correctness of our systems. These tools have been around for a while, but until recently the “Getting Started” material has been thin on the ground. In this talk I will show you how to get up and running and ready to build stuff with a Rails-like framework underpinned by one of the fastest and most stable languages in the industry: Haskell. The talk will cover everything from setting up a development environment, to integrating with a database and deploying to a VPS. Although this is a Haskell talk, it's from an angle of pragmatism and not academia. You do not need to know Haskell to enjoy this talk.

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.

Michael Brown @browniepoints - Becoming Reacquainted with UML

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.

In this session, Michael Brown will serve as an archaeologist of sorts, giving participants a tour of approaches to leverage UML as a tool for discovery, verification, and rapid enhancement of a Domain Driven business solution.

[SLIDES]Ali Kheyrollahi @aliostad - From hard science to baseless opinions: where did we go wrong?

From the mathematicians and scientists of the 20th centuries to today's ninja craftsmen/craftswomen, Software community hast lost something along the way. Instead of carefully observing scientific methods and maintaining objectivity, we have tangled ourselves in web of hype, and celebrity culture - as if adopting today's YOLO motto. We have completely forgot how to reason scientifically about matters of technical dispute, instead, whoever is more opinionated or shouts louder wins - as if software is an abstract art where you can only form an opinion. This talk is a critique of the status quo. With a survey of the history of software, we will try to find our roots highlighting the wrong footsteps we have taken as an industry. It also shines a ray of light with the recent rise in adoption of scientific methods as a result of pick up in Machine Learning and Data Science.

[SLIDES]Tomer Gabel @tomerg - How shit works: the CPU

The beautiful thing about software engineering is that it gives you the warm and fuzzy illusion of total understanding: I control this machine because I know how it operates. This is the result of layers upon layers of successful abstractions, which hide immense sophistication and complexity. As with any abstraction, though, these sometimes leak, and that's when a good grounding in what's under the hood pays off. The second talk in this series peels a few layers of abstraction and takes a look under the hood of our "car engine", the CPU. While hardly anyone codes in assembly language anymore, your C# or JavaScript (or Scala or...) application still ends up executing machine code instructions on a processor; that is why Java has a memory model, why memory layout still matters at scale, and why you're usually free to ignore these considerations and go about your merry way. You'll come away knowing a little bit about a lot of different moving parts under the hood; after all, isn't understanding how the machine operates what this is all about?

[SLIDES]Sven Peters @svenpet - Rise of the Machines - Automate Your Development

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! Even if I save you just half an hour a week, this talk will be a beneficial investment of your time.

Let's face it - concurrency is hard. Deadlocks, race conditions - these make your head hurt quite often, and trying to debug those issues only adds up more pain. Why don't we try to avoid those and still have our programs run concurrently? But can we do that? YES! Meet Pony. Pony is an object-oriented, capabilities-secure programming language with an actor model implementation at its core - here "actor" is a keyword! Pony is fun because it fixes most issues of concurrent programming. In the world of Pony it's the compiler that tells you whether your program is safe to execute. It's also type-safe, has no runtime exceptions and you can even use lambdas! I'll show you some examples of Pony programs, how its type system works and how capabilities render your concurrency safe.

[SLIDES]Mathias Brandewinder @brandewinder - Agile experiments in Machine Learning with F#

Just like traditional applications development, machine learning involves writing code. One aspect where the two differ is the workflow. While software development follows a fairly linear process (design, develop, and deploy a feature), machine learning is a different beast. You work on a single feature, which is never 100% complete. You constantly run experiments, and re-design your model in depth at a rapid pace. Traditional tests are entirely useless. Validating whether you are on the right track takes minutes, if not hours.
In this talk, we will take the example of a Machine Learning competition we recently participated in, the Kaggle Home Depot competition, to illustrate what "doing Machine Learning" looks like. We will explain the challenges we faced, and how we tackled them, setting up a harness to easily create and run experiments, while keeping our sanity. We will also draw comparisons with traditional software development, and highlight how some ideas translate from one context to the other, adapted to different constraints.

Mark Seemann @ploeh - Functional Architecture: the Pits of Success

Object-oriented architects and developers have, over the years,
learned many hard lessons about successfully designing systems with
object-oriented programming. This has led to a plethora of ‘best
practices’ that are painfully passed on from older to younger
generations via books, lectures, consulting, blog posts, etc. Many of
these ‘best practices’ must be explicitly taught, because they don’t
evolve naturally from object-oriented programming. Surprisingly, many
of these hard-won ‘best practices’ fall naturally into place when
applying functional programming. Instead of deliberate design,
functional programming forms pits of success where you naturally fall
into the same ‘best practices’ that you have to deliberately work for
in object-oriented programming. In this session, you’ll learn about a
handful of such ‘best practices’, and how functional programming
automatically leads you there, without your explicit effort.

[SLIDES]Pawel Szulc @rabbitonweb - Going bananas with recursion schemes for fixed point data types

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.

[SLIDES]Eleanor McHugh @feyeleanor - Implementing Software Machines in Go and C

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.

[SLIDES]Ali Kheyrollahi @aliostad - 5 must-have patterns for your web-scale Microservices

Building a service/Microservice is itself
easy. Scaling it on the cloud is not that hard either but operating,
maintaining and iterating a production large scale service is not just
about linearisation. As Cockcroft points out, telemetry and monitoring
is the most important aspect of building Microservices We discuss 5
patterns that any serious Microservice should have: - Canary (an
endpoint reporting health of underlying dependencies) - IO monitor
(measuring all calls from Microservice to external dependencies) - A
circuit breaker - An ActivityId-Propagator - An exception and short
timeout retry policy Apart from the Microservice buzzword, there is a
saddening lack of understanding of what a successful Microservice
architecture requires in terms of monitoring and telemetry. MTR in
case of a Microservice can be much more than a monolith if these 5
patterns are not in place.

[SLIDES]Kevlin Henney @KevlinHenney - Worse Is Better, for Better or for Worse

Two-and-a-half decades ago, Richard Gabriel proposed the idea of “Worse Is Better” to explain why some things that are designed to be pure and perfect are eclipsed by solutions that are seemingly compromised and imperfect.

This is not simply the observation that things should be better but are not, or that flawed and ill-considered solutions are superior to those created with intention, but that many solutions that are narrow and incomplete work out better than the solutions conceived of as being comprehensive and all encompassing. Whether it is programming languages, operating systems, development processes or development practices, we find many examples of this in software development, some more provocative and surprising than others.

In this talk we revisit the original premise and definition, and look at how this approach to development can still teach us something surprising and new about code, architecture, process and product design.

[SLIDES]Dylan Beattie @dylanbeattie - Webmasters, Full Stack Developers and Other Legends

Once upon a time, when the web was young, phones were dumb and people still thought progressive JPEGs were a pretty neat idea, there were people who called themselves... THE WEBMASTERS. They were brave, they were bold. Armed with a 56k modem and a stack of O'Reilly books, the webmasters were fearless in their ongoing quest, driven by a humble vision - to connect the entire world together. Using Netscape Navigator. Of course, that was a long time ago, and nobody really believes the stories any more. Some say the webmasters are gone. Some say they never existed in the first place - it was just a bunch of marketing people with delusions of grandeur. But a few, a select few, believe they changed. They evolved. They learned new skills, they embraced new technology... and the Legend of the Full Stack Developer was born. The history of software development is rich with tales of extraordinary individuals, whose knowledge of their own systems was absolutely unrivalled. But here in 2016, in a world where distributed systems, machine learning and autoscaling cloud systems are ubiquitous and the average web app uses three JavaScript frameworks, four server-side languages and six different kinds of caching technology, does it really make any sense to talk about full stack developers? Are we clinging to outdated paradigms, nostalgic for the simple days when one person really could know all the answers - or does overspecialisation represent a genuine threat to the established discipline of software development? And if it does - should we be resisting it, or embracing it as a change that's long overdue?

[SLIDES]Motiejus Jakštys @mo_kelione - Understanding and building your own Docker

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.

[SLIDES]Paul Stack @stack72 - The Biggest Trick Consultants Ever Pulled was Convincing The World Continuous Delivery Was Easy

Continuous Delivery and DevOps are practices that will help enhance
the quality of an organisation and it's products. However it's
unfortunate that both have also become practices that consultants will
try and sell whilst telling us we can implement a check list to
achieve it. This couldn't be further from the truth.

Did you know that you can practice continuous delivery regardless of
being a startup or an enterprise? Did you know that continuous
delivery can still be achieved no matter if you work on Windows or
Linux?

This session will focus on the most common misconceptions that exist
within continuous delivery and devops eco-system right now. The
session will given battle hardened stories about why these
misconceptions are bad practice and suggest some alternatives that may

[SLIDES]Mindaugas Mozūras @mmozuras - Engineering for Engineering's Sake

Code is a not an asset. Technology is not the solution to your company problems. And engineering for engineering's sake is not the answer. As engineers, we tend to focus a lot of our time thinking about "how?". How to solve this problem? How to structure code? How to name this method? We forget to ask "why?" and ponder the usefulness and greater impact of what we're doing. We don't work in silos. What we do affects our users. But not only that. It also affects our teammates and other developers in our organisations. Let's talk about why, having aforementioned things in mind, we should aim to write less code. Use less and more mature technologies. And don't do engineering for engineering's sake.

[SLIDES]Sasha Goldshtein @goldshtn - Modern Linux Tracing Landscape

The Linux kernel has multiple "tracers" built-in, with various degrees of support for aggregation, dynamic probes, parameter processing, filtering, histograms, and other features. Starting from the venerable ftrace, introduced in kernel 2.6, all the way through eBPF, which is still under development, there are many options to choose from when you need to statically instrument your software with probes, or diagnose issues in the field using the system's dynamic probes. Modern tools include SystemTap, SysDig, ktap, perf, bcc, and others. In this talk, we will begin by reviewing the modern tracing landscape -- ftrace, perf_events, kprobes, uprobes, eBPF -- and what insight into system activity these tools can offer. Then, we will look at specific examples of using tracing tools for diagnostics: tracing a memory leak using low-overhead kmalloc/kfree instrumentation, diagnosing a CPU caching issue using perf stat, probing network and block I/O latency distributions under load, or merely snooping user activities by capturing terminal input and output.

[SLIDES]Alex West @birdsncherries - A Visual Thinking Warmup for developers

Do strong personalities dominate your development team? Are code reviews painful? Are you blindly following orders from a backlog, or are you learning from observation? Visual Thinking Strategies, or VTS, is a crossdisciplinary technique applicable to anyone working in a collaborative setting where observation is key. VTS develops critical thinking skills by viewing and discussing works of art in a group. It is backed by over 30 years of field research showing its effectiveness and accessibility. By allowing individuals to talk about art without needing a background in the field VTS advances skills you can use to create more relevant products and stronger teams: Observing, Brainstorming, Speculating, Reasoning with Evidence, Cultivating a Point of View, and Revision & Elaboration. During this interactive exercise, we’ll discuss selected works of art as a group. There are no right answers or group consensus being sought. We’re creating an environment and process for looking, thinking, reasoning and revision skills that are missioncritical to anyone working in a software design or development role. After our group discussion, I’ll introduce the basics of image selection and facilitating VTS sessions within your organization. In addition to the above, I’ll cover how VTS can help you and your team with the following: Comfort with Ambiguity, Openness to the Unfamiliar, Civil Debate, and Willingness to Participate in Group Thinking.

[SLIDES]David Ostrovsky @DavidOstrovsky - GPUs - Not Just for Graphics Anymore

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.

[SLIDES]Kevlin Henney @KevlinHenney - Functional C++

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.

[SLIDES]Rachel Appel @rachelappel - The Zen of UI Test Automation

You've spent time and effort to build a website, and you must verify that it works correctly. Especially the UI, which is arguably the most important part of any software - at least to the user. But you might be tired of manually testing webpages, as that is a tedious and error prone process. Have you ever asked yourself if there must be an easier way? If you have, you're in luck, as there are many ways to do so, including one called WebDriver that you'll learn about. In this session, you'll learn how to write a few lines of code that can replace all the manual Web UI testing that you or your QA people have been doing. Save yourself and your testers time and money by automating the process of testing user interfaces. You'll learn how to write a UI test one time that will run again and again, testing web pages so you can confidently make changes and maintain the code. We'll discuss how to automatically fill in forms, navigate, and do anything that the user might do, but automatically, with no user involved! UI automation tests are a great way to help ensure a higher quality of your software.

[SLIDES]James Geall @jageall - Consul Demystified: Exploring the principles behind better service discovery

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.

[SLIDES]Boyan Mihaylov @bmihaylov - Stop the Internet, I want to go offline

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.

[SLIDES]Jurgis Didžiulis @JurgisDid - From Spectate to Participate

A developer can do more than just develop products!A musical performance is a lot like a magic show. There are many tricks performers rely on to seduce an audience. Yet, the most powerful of all performance alchemy is when the ‘magician' reveals his bag of tricks and allows others become part of the magic. But much like with open source initiatives, certain conditions must be met for people to immerse and commit themselves to be part of the experience, rather than just be mere spectators.

"From Spectate to Participate" is a medley of music, ideas, and interaction that illustrates that an artist can do more than just entertain us. Or in your case – a developer can do more than just develop products. If you look problems playfully and allow others to get involved constructively, the results will often astound you.

Creativity isn’t just there to be consumed and appreciated from the safety of the sidelines; it beckons us to get down and dirty with it and our own creative nature.
