Quantum Party Tricks: An entertaining introduction to quantum computing

Although quantum computing concepts can seem strange and difficult to learn, many of them are easy to understand in the context of simple demonstrations. For example, a quantum bit (qubit) may hold the value of 0 or 1, or some combination of those values. When measured, the state of the qubit collapses to either 0 or 1, based upon the probabilities expressed in its hidden quantum state. A simple demonstration, or “quantum party trick” if you will, can shed light on this phenomenon as well as how it is leveraged in quantum computing.

In this session, James Weaver will give an entertaining introduction to quantum computing, After covering a brief history of quantum computers, James will demonstrate key concepts in quantum computing using several party tricks disguised as programs running on a quantum computer. By the end of this session, attendees will have been exposed to concepts and tools that enable them to develop programs that run on quantum computers.

Part of this session will consists of demonstrations using a block-mining application similar to Minecraft. Attendees may choose to download this game and play along before, during, and after the session by following the instructions at QiskitBlocks.org

Despite the many challenges in an ever-evolving technical world, she gets energized by the constant change and believes that she has uncovered the pathway to staying young. She can’t wait to see what the next tech wave will be like.

Thirst-Quenching Streams for the Reactive Mind

With the advances in multicore hardware and virtualization technologies, and the demand for highly responsive, resilient, and elastic systems and increasingly sophisticated applications, an array of reactive data stream processing libraries have been born to address the ever-increasing needs. Reactive Streams is an initiative to provide a standard for asynchronous stream processing with non-blocking back pressure. This encompasses efforts aimed at runtime environments that include JVM and Javascript, as well as network protocols. So how do the various library implementations of Reactive Streams, such as Spring Reactor, Reactive Extension (Rx)’s Observables, and RSocket, stack up against each other?

This presentation will go into some details on how streams leverage on the underlying multicore processor to achieve parallelism. It will then explain the push vs the pull streaming model. It will then use a simple use case with code examples to illustrate the different API usages, as well as runtime processing analysis between a few popular Java implementations of Reactive Streams.

Single page applications (SPA) have become the for web application development. Angular, React and Vue.js are the best known representatives from this category of web frameworks. But does this client architecture fit every application? Or are there alternatives that may fit better and are less complex to develop?

In the first part of the talk, the differences between SPAs and classic, server-side approaches are explained and the advantages and disadvantages are discussed.

The second part reports on a current customer project in which the front end of a large ERP system had to be replaced by a modern web front end. The chosen framework is Vaadin Flow, a server-side web framework that makes development of web applications entirely in Java possible.

First, the new architecture of Vaadin Flow, which is no longer based on GWT but on web components, is explained. Then it will be shown how configurable, form-based and data-centric web applications can be implemented very efficiently by using jOOQ as a database access layer.


Hugh McKee

Hugh McKee is a Developer Advocate at Lightbend. He has had a long career building applications that evolved slowly, that inefficiently utilized their infrastructure, and that was brittle and prone to failure. That all changes when we started building reactive, asynchronous, actor-based systems. This radically new way of building applications rocked his world. As an added benefit, building application systems became way more fun than it had ever been. Now he is focused on helping others to discover the significant advantages and joys of building responsive, resilient, elastic, message-based applications.

How We Code: From Loops to Functions, to Actors?

The history of how we write code has been fascinating. For the most part, from the early days back in the 1940s and 50s up to the present day, the imperative style or writing code as a linear sequence of instructions was the norm. Then along came the object-oriented, which is a refinement of the imperative style. In the last few decades, new programming languages came on the scene that promotes the functional style. During this evolution of programming styles, on the fringe is the actor model, which defines the concept of actors as computational units.

What is interesting from a historical perspective is that the imperative, functional, and actor paradigms have been well known and actively researched since the earliest days of computing and programming. The notion of “calculating machine,” the inspiration of imperative programming, goes back to the 1830s! Functional programming has its roots in Lambda Calculus, developed in the 1930s. The actor model, first conceived back in the 1970s, was inspired by physics.

Why is it that the imperative paradigm first became the predominant programming style? Why is it that the functional paradigm took so long to catch the attention of mainstream programmers? Finally, why has the actor model, which many have predicted should be the predominant programming model, struggled to go beyond the fringe?

In this talk, we will look into these questions and then zero in on the actor model. Through a series of code examples and visualizations, we will look at some of the fantastic and often unbelievable things you can build with actors. My goal for this talk is to inspire you to seriously consider the actor model for some of your future projects.

Francis founded Contramap, a Canadian consulting company providing technical expertise regarding functional programming, reactive system design and training, through talks, blog posts, open-source contributions, and development.

 

Functional Design

Software design is hard but doesn’t have to be. Fifteen years ago, my mentor made me realise that maintainable and sustainable design matters immensely. However the amount of principles and best practices one has to know to achieve this is very intimidating. Moreover they tend to be either too vague or way too specific and it requires years and years of practice to be got right. Too often, we end up falling back on “good enough” approaches (which can be pretty limited in the long run) or over-complicated ones resulting from a zealous application of the above guidelines. In fact all these principles and best practices share some common ideas which all together form the fundamental set of guidelines we should all know about to write sustainable code.

In this talk, we’ll look at what Functional Design consists of and how it can lead us to techniques to write better software no matter the paradigm you are used to.

Java at Speed: Building a Better JVM

Getting the best performance out of your Java applications can often be a challenge due to the managed environment nature of the JVM and the non-deterministic behaviour that this introduces.

This session will start by looking at what we mean by speed and how the JVM, whilst extremely powerful, means we don’t always get the performance characteristics we want. We’ll then move on to discuss the three critical features of the Zing JVM that address these issues:

  1. The C4 garbage collector, which eliminates GC pauses that affect the performance of an application even after all hot code paths have been compiled and optimised.
  2. The Falcon JIT compiler that leverages the LLVM open source project to provide optimisations specific to the newest CPU architectures using features like AVX2.
  3. ReadyNow!, which allows details of speculative optimisations and JIT profiling to be logged on production systems. ReadyNow! profiles can then be used to substantially reduce the warmup and deoptimisation issues that affect performance when restarting an application.

Local Variable Type Inference: Friend or Foe?

Local variable type inference was introduced as a new Java language feature in Java SE 10. Gone are the days of explicitly having to define the type of a variable; let the compiler do it for you with the magic of var!

At first sight, this looks like a small change that will eliminate unnecessary boiler-plate code and reduce how much typing (on the keyboard) is required to maintain strong typing (of the language). However, as with many features, there are some unexpected nuances as well as both good and bad use cases.

In this session, we’ll explain the fundamentals of local variable type inference and look at the edge cases where it can, can’t, should and should not be used. We’ll then take a series of examples of the use of var and discuss the technical merits of each case.

This stupid multi-threaded code isn’t working. I hate Java!

Let me step in here. Java is probably the most deterministic language ever. But reading the Java Memory Model specification is not like reading Harry Potter and the Philosopher’s Stone. It is shorter though. Fortunately, I have tricks. Let’s have a look together.

We will go through different examples. The idea is not fully to understand the model (nobody does) but to have solid examples that work. To spend less time looking at a concurrency idiom wondering if you are safe or not.

Of Concurrency and other demons

Is your code too slow? Users must wait for one task to be done after moving to the next one? Have you heard that you can use threads in Java but you struggled with them and never quite understood how they work? In this session Hillmer and Rodrigo will demonstrate how with a few changes -and low effort- in the code and using the CompletableFuture API, even a single app can do more than one thing at time improving the response times.

Intellectual property for software inventions / La propriété intellectuelle et les inventions logicielles

Few things change faster or more continuously than technology. The term “software invention” has been used to refer to many different types of innovation in different technological fields. In particular, this term has been used to encompass all inventions that use some type of computer software program in their implementation. What does intellectual property have to do with software? Is it true you can’t get a patent on software? What are the benefits of protecting your software, and how do software companies use intellectual property? We will answer all these questions and more.

Peu de choses changent plus vite ou plus continuellement que la technologie. De nos jours, le terme «invention logicielle» est utilisé pour désigner de nombreux types d’innovation dans différents domaines technologiques. En particulier, ce terme est utilisé pour englober toutes les inventions qui utilisent un certain type de logiciel informatique dans leur mise en œuvre. Qu’est-ce que la propriété intellectuelle a à voir avec les logiciels? Est-il vrai que vous ne pouvez pas obtenir de brevet sur un logiciel? Quels sont les avantages de la protection de vos logiciels et comment les entreprises informatiques utilisent-ils la propriété intellectuelle? Nous répondrons à toutes ces questions et plus.

Using WebComponents with Java on the server-side and how to harden the stack against known Vulnerabilities

In recent years, the interest and use of web components in the community have increased significantly. Most front-end frameworks adopt the Web Component standard, and many developers have started using the norm when creating their widgets. Not to mention that it is now natively supported by all modern browsers. How to use the interoperability and flexibility of web components as Java developers on the server-side? This talk shows the use of pure client-side web components using Java on the server-side. We will have a look at the tech-stack, how it looks like for a developer and how to harden against known vulnerabilities.
