You Can Do Better With Kotlin – SVETLANA ISAKOVA – 26, 27 Sept

 

SUMMARY

This YOW! Night is devoted to the Kotlin programming language. It’s a modern language that gives more power in everyday routines and is gaining popularity amongst the Java developer community.

Kotlin code generally looks cleaner and nicer, and it’s much easier to work with when you have less verbosity or code duplication. But what’s even more important, is that Kotlin is 100% compatible with all existing Java frameworks, and has good tooling (it’s from JetBrains after all).

Our agenda for the night consists of three parts:

  • Introduction to the language
  • Introduction to Kotlin Coroutines
  • Practical sides of Java interop

At first, we’ll discuss what makes Kotlin so attractive to developers and cover the most important features of the language. Then, we’ll talk about coroutines, a new powerful feature, that changes your habits of writing asynchronous code. The last part is aimed mainly at people who already have some experience with Kotlin and dives into some internals of mixing Java and Kotlin code in one project.

The Joy of Vector Programming – Dave Thomas – 5, 13 Sept

 

SUMMARY

In this talk, Dave and Tom will explain why vector or array programming (technically applicative functional programming) is so empowering and important in a data driven world. Many experienced vector programmers will be surprised to learn how vector programming applies outside of finance to unstructured applications such as text analytics, graph analytics and visual analytics. Dave will also discuss recent hardware innovations that can be leveraged by vector programming. YOW Night attendees will have the opportunity to meet and talk with vector developers employed in both real-time streaming and big data analytics.

Lake, Swamp or Puddle: Data Quality at Scale – 22, 23, 24 Aug


SUMMARY

Data is a powerful tool. Data-driven systems leveraging modern analytical and predictive techniques can offer significant improvements over static or heuristic driven systems. The question is: how much can you trust your data?

Data collection, processing and aggregation is a challenging task. How do we build confidence in our data? Where did the data come from? How was it generated? What checks have or should be applied? What is affected when it all goes wrong?

This talk looks at the mechanics of maintaining data-quality at scale. Firstly looking at bad-data, what it is and where it comes from. Then diving into the techniques required to detect, avoid and ultimately deal with bad-data. At the end of this talk the audience should come away with an idea of how to design quality data-driven systems that ultimately build confidence and trust rather than inflate expectations.

The Power of the Network – ANDREW BETTS – 8, 10, 14 Aug

 

SUMMARY

Web developers are increasingly responsible for the performance of the sites they build, and there is now a plethora of advanced tools and services that allow developers to hone front end performance as never before. But the network can still be your biggest bottleneck.

This talk will discuss best practices and creative strategies for using caching, purging, preloading, server push, streaming, and other technologies to make sure your site hits your user’s browser at top speed.

The JavaScript Workers: An Introduction to Web & Service Workers

Historically, we have developed web applications with the assumption that the end user is connected to the internet. With the ever increasing browser support of Service Workers, however, this assumption is quickly becoming outdated: developers now have the opportunity to create websites that can work offline, independent of network status, with great flexibility.

But let’s take a step back: what is the Service Worker API? How does it enable developers to develop web applications with offline capabilities? To help answer these questions, one should look to its predecessor: the Web Worker API. By understanding what the Web Worker API provides us (and what it doesn’t), we can better understand Service Workers and how to use them.

Application Delivery and Release Management – VINCENT DE SMET – 9 Aug

 

SUMMARY

Adoption of Agile methodologies for application development requires companies to adopt a culture of shared responsibilities between Developers and Operators. A major facilitator in adopting this DevOps culture has been the rise of Linux Containers. A new ecosystem of tools and systems around Linux Containers is evolving at a fast pace to simplify the Developer experience, CI/CD pipeline setup as well as Application release rollouts, rollbacks, autoscaling and configuration.In this talk, we will focus on selected frameworks and how these simplify the creation of a cluster of load balanced, resilient and self healing web applications. We will look at key requirements for container adoption and how the Kubernetes orchestration system and Helm deployment manager fulfil these. We will start with the base concept of Linux Containers and the tools introduced by Docker and look at the underlying concepts Kubernetes and Helm are built on.

The Internet Of Scary Things – CHRISTOPHER BIGGS – 29 July

 

SUMMARY

The Internet of Things (IoT) has recently been somewhat of a laughing stock, with poorly designed and managed IoT devices being associated with severe privacy leaks, theft of service, and botnet-perpetrated denial-of-service attacks. The currently circulating joke goes “The S in IoT stands for Security!”

This presentation covers how to recognise and avoid risks to your business from adopting IoT, some best practices for selecting and deploying IoT devices, and most importantly, for developers of IoT products, how to avoid repeating the mistakes of the past, through good architecture, quality processes and use of the right tools and frameworks. I will talk about ways to ensure that less-secure or rogue devices cannot damage your network or the Internet at large, how to monitor and control your IoT devices to keep them safe and functional, and how to choose among the growing collection of incompatible frameworks for IoT systems.

IoT is the Wild West – Criminals have outrun the Law, but the Law, and good development practices, are catching up. My presentation will teach you about the guidelines, traps, tools and frameworks that you need to know about to avoid becoming the next “IoT is…” joke.

Property Based Testing – CHARLES O’FARRELL – 18, 19 July

 

SUMMARY

Testing is an essential part of writing and maintaining correct and reliable software. However, for the most part the best technique we have for writing tests is to capture some examples in the hope that they cover all the known edge cases. Unfortunately these examples almost always missing something.

What if we could ask the computer to generate these examples? Not just a handful, but hundreds of them that we never even considered. It turns out we can! By using the technique known as Property Based Testing.

This talk will explore the motivation and concepts behind this powerful testing technique. We also introduce a number of simple but useful patterns that can be applied again and again when writing properties. In addition this talk will highlight a handful of compelling examples of Property Based Testing uncovering nasty bugs in real world software.

Finally, apart from learning about why and how to use Property Based Testing to write better software, the audience will also realise that testing can be made more enjoyable in the process.
