Our increasingly connected world leveraging the Internet of Things (IoT) creates great value, in connected healthcare, smart cities, and more. The increasing use of IoT also creates great risk. We will discuss the challenges and risks we need to address as developers in TIPPSS - Trust, Identity, Privacy, Protection, Safety, and Security - for devices, systems and solutions we deliver and use. Florence leads IEEE workstreams on clinical IoT and data interoperability with blockchain addressing TIPPSS issues. She is an author of IEEE articles on "Enabling Trust and Security - TIPPSS for IoT" and "Wearables and Medical Interoperability - the Evolving Frontier", "TIPPSS for Smart Cities" in the 2017 book "Creating, Analysing and Sustaining Smarter Cities: A Systems Perspective" , and Editor in Chief for an upcoming book on "Women Securing the Future with TIPPSS for IoT." 

Unison is a new purely functional programming language, currently under development. Unison treats any pool of networked machines as if they formed a single supercomputer, and lets you program this supercomputer simply and directly. This talk will introduce the Unison language, its type system, runtime, and developer experience, as well as the core ideas that make Unison unique.

The 20th Century was transformed by the ability to program on silicon, an innovation that made possible technologies that fundamentally revolutionised how the world works. As we face global challenges in health, food production, and in powering an increasingly energy-greedy planet, it is becoming clear that the 21st Century could be equally transformed by programming an entirely different material: biological matter. The power to program biology could transform medicine, agriculture, and energy, but relies, fundamentally, on an understanding of biochemistry as molecular machinery in the service of biological information-processing. Unlike engineered systems, however, living cells self-generate, self-organise, and self-repair, they undertake massively parallel operations with slow and noisy components in a noisy environment, they sense and actuate at molecular scales, and most intriguingly, they blur the line between software and hardware. Understanding this biological computation presents a huge challenge to the scientific community. Yet the ultimate destination and prize at the culmination of this scientific journey is the promise of revolutionary and transformative technology: the rational design and implementation of biological function, or more succinctly, the ability to program life.   

What happens to retired computer scientists? Easy now they can work almost full time on their hobby projects - no more boring meetings, no more scrum and agile.

In this talk, I'll tell you some of the projects I've been working on in my spare time - I've been working on some of these problems for 40 odd years but haven't made much progress, so all ideas on how to solve them are welcome.

If you're an angler fish, you have it rough. You spend your life in the deep sea. It's lonely. Mates are hard to find. What do you do? If you're the male Whipnose Seadevil, you spend your life exclusively in search of that elusive, life long companion. You take this task so seriously that you forgo physical development and accept a stunted life -- that is until you fix yourself to a female, and release an enzyme that digests the skin of your mouth and her body, fusing you and your new-found love down to the blood-vessel level. And so you
become dependent on her for survival, receiving nutrients via your newly formed shared circulatory system. In return, you provide valued sperm.

And therein lies the secret to building great software.

In this talk, Greg Young will make the case that polyandry and parasitic reproductive processes should serve as the model for programming. You'l learn how the Whipnose Seadevil adapts pragmatically to its deep sea environment and manages to accomplish what most of us as programmers only dream of: reduced metabolic costs in resource-poor environments and improved lifetime fitness relative to free-living competitors.

Don't miss this opportunity to learn from one of software's great visionaries!
 

Leadership is easy when you're a manager, or an expert in a field, or a conference speaker! In a Kanban organisation, though, we "encourage acts of leadership at every level". In this talk, we look at what it means to be a leader in the uncertain, changing and high-learning environment of software development. We learn about the importance of safety in encouraging others to lead and follow, and how to get that safety using both technical and human practices; the necessity of a clear, compelling vision and provision of information on how we're achieving it; and the need to be able to ask awkward and difficult questions... especially the ones without easy answers.

Complexity in systems should be defeated if it is possible to do. But the default nature of our computer systems are complex and servers are doomed to fail. In this talk, we will go through new approaches in modern architectures to design and evaluate new computer systems.

As we edge towards larger, more complex and decoupled systems, combined with the continual growth of the global information graph, our frontiers of unsolved challenges grow equally as fast. Central challenges for distributed systems include persistence strategies across DCs, zones or regions, network partitions, data optimization, system stability in all phases. 
 
How does leveraging CRDTs and Event Sourcing address several core distributed systems challenges? What are useful strategies and patterns involved in the design, deployment, and running of stateful and stateless applications for the cloud, for example with Kubernetes. Combined with code samples, we will see how Akka Cluster, Multi-DC Persistence, Split Brain, Sharding and Distributed Data can help solve these problems.  
 

Event Stream Processing is a popular paradigm for building robust and performant systems in many different domains, from IoT to fraud detection to high-frequency trading. Because of the wide range of scenarios and requirements, it is difficult to conceptualize a unified programming model that would be equally applicable to all of them. Another tough challenge is how to build streaming systems with cardinalities of topics ranging from hundreds to billions while delivering good performance and scalability.

In this session, Sergey Bykov will talk about the journey of building Orleans Streams that originated in gaming and monitoring scenarios, and quickly expanded beyond them. He will cover the programming model of virtual streams that emerged as a natural extension of the virtual actor model of Orleans, the architecture of the underlying runtime system, the compromises and hard choices made in the process. Sergey will share the lessons learned from the experience of running the system in production, and future ideas and opportunities that remain to be explored.

There's a story to tell, about musicians, artists, philosophers, scientists, and then programmers.
There's a truth inside it that leads to a new view of work, that sees beauty in the painful complexity that is software development.
Starting from _The Journal of the History of Ideas_, Jessica traces the concept of an "invisible college" through music and art and science to programming. She finds the dark truth behind the 10x developer, a real definition of "Senior Developer," and a new name for our work and our teams.

An Operator is an application that encodes the domain knowledge of the application and extends the Kubernetes API through custom resources. They enable users to create, configure, and manage their applications. Operators have been around for a while now, and that has allowed for patterns and best practices to be developed.

In this talk, Lili will explain what operators are in the context of Kubernetes and present the different tools out there to create and maintain operators over time. She will end by demoing the building of an operator from scratch, and also using the helper tools available out there.
