The only certainty in JavaScript is change. There is a new, cool framework popping up seemingly every week. jQuery, Knockout, AngularJS: all were once the darlings of the web, now relegated to the scrapheap of legacy. One day you will abandon your current favourite framework too, as it slowly falls out of fashion. How then do you choose an appropriate JavaScript framework? How do you make sure that the next framework is the one? Better still, how can you work with your favourite framework today, while still working within your legacy application?
What if you don’t have to choose the right framework? What if legacy never got in your way? Join me as I show you how you can take lessons from MicroServices and use them to let you work with new, exciting frameworks even in applications based on older, legacy, technology (no microservices required)
A professional geek, William works for Particular Software writing amazing software like NServiceBus. Passionate about the web and security, he is engaged in a sordid love affair with JavaScript and spends most of his free time trying to convince others of its beauty and elegance.
When not behind his laptop hacking away, this amateur beer enthusiast can often be found playing board games or drinking cold-brew coffee.

If those who can’t remember history are doomed to repeat it, maybe it’s time for us to look back at inspiring women who shaped the modern world. Featuring heroines such as Ada Lovelace, Margaret Hamilton and Grace Hopper, let’s dig into the history of women in technology, in order to look forward.
Christina Burger is a senior software engineer from Durban. She specialises in front-end development for online games, focusing on performance optimisation and investigating new technologies. She is passionate about software craftsmanship, life-long learning and supporting tech communities. She holds a master's degree in Computer Science and a love-hate relationship with JavaScript. When she is AFK, she's usually reading, sewing or irritating her cat.
Rory Preddy
My life is a hilarious roller coaster of miss-intended programming bugs because at 4 foot tall and 65 kilograms I completely fall off your radar.
What did my scale call me! Why does facial recognition see me as a child? These are all valid questions I often ask myself as I navigate my weird and different world. Have you heard the phrase “You have to be this tall for Micro-services”? well, what about: “You have to be this tall to operate a mobile phone?”. I am finding it harder and harder to reach any button except for “#” and “9”.
Building accessibility into the planning stages of programming can eliminate barriers for participation and create an inclusive environment for people with disabilities. Programming for diversity serves as an unquestionable indicator that your software embraces the diversity of your users and cares about their safety and comfort.
Join me on a fascinating and thought-provoking look at how you can program for accessibility.
At 124 centimetres (or 4' 1") tall, Rory's life is a hilarious roller coaster of miss-intended adventures and challenges. Rory is lucky enough to work full time in R&D and an organizer for the Jozi-JUG and AWS-Jozi. He spends his time between enabling developer communities and his overly hyperactive wife/kids/dogs.
Gareth Stephenson
For my Masters degree research project, I chose to perform a controlled experiment with a group of volunteer software developers. The experiment was to test the theory that Mob Programming positively affects team communication and learning, compared to working in a self-organised team formation. One requirement of the experiment was for the volunteers to complete a "Big Five" personality traits assessment, to see how they scored against the traits of Openness to Experience, Conscientiousness, Extraversion, Agreeableness and Neuroticism.
The data collected from the assessment, along with the answers from the questionnaire at the end of the experiment, provided some valuable, quantitative insight that could be of great value to anyone who works in a software development team.
In this talk, I present the findings of the experiment and what it could mean for you and your team.
Gareth has spoken at various conferences and user groups throughout South Africa on topics ranging from software development to building cluster-computing systems using Raspberry Pi's. He's been working in the software development field for over 20 years, and he's still no good at it.

Jade Abbott
How often have you had to advise to a client which cloud provider to use? Our usual answer, as developers, is "It doesn't make much of a difference". That said, we've had a bundle of scenarios where there are subtle differences between the providers that can make a big impact.
So we're putting the 3 big cloud giants (AWS, GCloud and Azure) against each other on 3 different REAL WORLD applications:
1. A system with high-compute and memory and scalability requirements. 2. A web system with a high number of request requirements. 3. A system with extreme database/data requirements.
We want to learn which cloud provider can do it (a) the cheapest (b) with the most ease (c) the best performance (d) with the best debugging and support. So that next time a client asks us "which one?", we can give an empirical answer
Jade Abbott is a Senior Software Developer and Data Scientist at Retro Rabbit. Since 2013, she's built software for every field from social upliftment to banking, working on projects throughout Africa.

Felix Wu
Unit Tests measure the quality and effectiveness of your production code. But ever wondered how effective and relevant your tests are? Meet Mutation Testing: Bugs, so-called Mutants, wrong return values, for example, are automatically inserted into your code to test whether your tests fail - if they do, the mutant dies, if they pass, the mutant survives. The higher the percentage of mutants killed, the more effective your tests are. In this talk, I will introduce the attendees to this relatively simple, but ingenious way of checking that your tests will spot malfunctioning code, and show some live mutation testing in different languages.
Felix is a 17 y/o Software Engineer from Germany. Besides school, he helps companies all around the world building their technical infrastructure as a part-time Frontend Consultant for TNG Technology Consulting. In his free time, he is an active Open Source contributor and the co-creator of the JavaScript snippet collection 30-seconds-of-code and a platform for tech interviewees called 30-seconds-of-interviews. He currently also maintains react-perf-devtool. When not coding, you can find him talking or reading about it, as well as advocating for Youth in Tech and organizing CSSFrankfurt. He also loves travelling, especially with his girlfriend, and playing basketball and frisbee, as well as hanging out with friends. Like many young people, he also loves going to parties! So far, he has done mostly JavaScript stuff at Runtastic, GEZE and TNG Technology Consulting.
Claire Wood
Did you know, a diverse team is 35% more likely to produce above-average results? From the science behind why diversity boosts performance, to why being the only woman in your project team is more of a problem than you might think, this talk takes a closer look at the realities of inequality in our industry, how each one of us has a role to play in the solution and what we should be doing to move our industry forward.
If you’ve ever wondered about how we improve diversity in software engineering, or if you’ve never wondered, then this is the right room for you.
Twenty years in the industry, fifteen of which as a hiring manager, seven at board level, four as a reformed unicorn (you’ll have to attend to hear that story) has given Claire a fairly well-rounded view of where we’re still going wrong with equality in software engineering and made her an enthusiastic champion of improving gender parity in STEM education. She once built a LEGO Death Star.
Ryan Kotzen
So many aspects make up being the best developer you can be yet we tend to focus almost exclusively on the obvious ones like learning the next library, framework or methodologies. Here we will explore some critical practices you may be missing that will not only improve your craft but your life. Our industry moves fast, there are new libraries and frameworks created every day, not to mention all the updates and features added to the ones we already use and love. There is a constant drive to deliver more, to increase velocity, to meet and exceed deadlines. We celebrate the culture of “being totally swamped” and wear it as a badge of honour. Impostor syndrome is real and can make us feel like we have to keep up with everything and it’s just simply not possible to do so. We don’t let this simple fact stop us from trying and we make bad trade-offs that are actually detrimental, leaving a trail of destruction through our bodies, our minds and sometimes even our family and friends. What if I told you that the world you live in is a prison for your mind, that it doesn’t have to be that way? As The Oracle told Neo, you will have to make a choice. There are techniques that will allow you to lead a better life, some you may already know but just don’t practice and some may be more esoteric. In this talk I will be distilling the years of self-help research and practice that I have personally gone through to show you how you can improve the quality of your life, not just to make you a better, more effective developer but a happier more grounded person. Naturally, as we are all in the tech field, I will be showing you some really awesome tech solutions to help you on your journey.
Some of the topics we will be looking at are:
Ryan Kotzen is an aspiring stoic, essentialist, polymath, polyglot software engineer, and armchair philosopher. Ryan is a believer in constantly evolving and evaluating what you are doing, utilising concepts from lean, kaizen, XP and the agile manifesto to name a few. Ryan has a passion for coaching and learning from other people. When not developing software, Ryan likes to spend his time airbrushing, geeking out on a geeky movie/series/book, playing Kerbal Space Program and all aspects of the Warhammer 40k hobby.

Liam Norman
Level: Intermediate. In this talk, We will focus on how to split up an old enterprise application which has become a monolith into microservices. We will examine the pros and cons of doing so and also the best design practices and architecture decisions that will ensure this process is a success.
We will mainly explore how to identify services in your monolithic application, identify seams in your monolith. We will also investigate how to decouple microservices from monoliths and the best practices when doing so. We will also focus on microservices development and DevOps such as scalability, load-balancing monitoring and reliability.
We will be examining how to extract a monolith application using example PHP/Laravel microservices that were pulled out of a larger legacy Laravel application. I will also investigate some war stories on how Superbalist achieved this and the lessons learned along the way.
At the end of the talk, you will know better how to refactor your monolith and improve your own architecture.
Liam Norman is a software engineer at superbalist.com and organiser of the PHP Cape Town user group. With experience working on monolithic systems, SOA systems, smaller SPA systems as well as API's. He has a passion for TDD, Laravel, CI/CD, and API Development. When not coding late into the night, he can be seen hiking table mountain or dabbling with anything code related.

Karl Fischer
Where Test-driven development and Infrastructure as code have a love child.
Everything around you is made up of atoms, DNA or code, there is a recipe on how everything is put together, and like most things... as soon as things get created organically it gets messy. With the advent of composable infrastructure or infrastructure as code, we need to focus more on getting reproducible systems as opposed to a patchwork of chaos. Using Test Driven techniques we can create and implement reliable, repeatable infrastructure.
Some slides, lots of memes and of course gorgeous un-canned demos
Karl has been a Linux User since 1999, he loves open source and free software, He is currently a DevOps lead at Obsidian Systems, hates long walks on the beach and I’m happily married with lots of children.
Helge Reikeras
In this talk, we'll dispel the common myth that you need a room full of PhDs to implement data science and machine learning into your software product. We'll present data science and machine learning as another tool that everyone involved with building software should have in their toolbox. We'll talk about the concepts, tools, and resources that a software developer needs to get familiar with, the value that data science and machine learning can bring to a software product, and how to get started doing it yourself.
Helge is a data scientist with 6+ years of experience in the practical implementation of products and services across a multitude of industries including insurance, banking, retail, and human resources. He is currently a data scientist at Offerzen.

Matt Cavanagh
Welcome to 2019: You Twitch-stream your ironing, your car thinks it is smarter than you, and catapults have Wi-Fi!
We’re going to go through using game-engine physics simulations (because ALGORITHMS!) to design and optimize a small self-loading desk catapult design, then CAD’ing it for 3D printing, and finally hooking it up to an Arduino to control from a phone over Wi-Fi.
This isn’t your grandfathers' catapult! (Unless you give it to him, I guess?)
Matt Cavanagh is a developer from Durban who hates writing bios in the third person. He started a company called roguecode making Windows apps, but then decided to be poor was a better idea so went into game development. He’s done talks at conferences like DevConf, and TechEd (when Microsoft still knew SA existed).
Justin Slack
It doesn't seem so long ago that front-end developers were employing all manner of techniques to use more than just the set of fonts installed on the user's computer. Now we have @font-face, OpenType features, WOFF (a font format specifically optimised for the web), and variable fonts. These developments allow us to create rich typographic experiences. But these experiences come with a performance cost: web pages become bigger and heavier. That means slower pages and more data to load.
This talk will cover the intersection of beautiful web typography and performance. We'll discuss the history of fonts on the web, how to enable rich typographic features, and how to load web fonts efficiently. We will cover typography and how it affects reading, a history of @font-face in the browser, Open type font features - like ligatures, lining numbers, stylistic sets - and how to use them, font loading strategies for optimal performance, and the future of web typography, variable fonts.
Audience level: All
Justin Slack is head of design, user experience, and front-end development at NML, a specialist financial services software development company. He is fluent in HTML and CSS, and slightly obsessive about typography, web standards, and user experience. He is co-founder and organiser of the Cape Town front-end developer Meetup group that has held monthly talks and workshops since 2013.
Chris Tite
We use time boxed cycles, shorter feedback cycles and small defined outcomes to run software projects. Why not use this approach to mentor and grow staff?
Why do we subject our teams to a sterile and delayed feedback KPA / KPI approach in the tech industry, an industry that is growing and experiencing rapid change?
These are all questions that puzzled me.
Four years ago I started mentoring team members using an agile approach which was refined over time and with each iteration, it is now an accepted and valued practice on all my teams.
This is my story.
In this talk I'll unpack;
* The agile mentoring approach and the mentoring life cycle * The different personas and people patterns adopted in agile mentoring * The tools used to manage the process * The career framework applied * Lessons learned
Join me as I share a fresh approach to mentoring team members which ultimately results in;
* Higher job satisfaction and less burn-out among employees * More confident teams with focused learning outcomes * Higher staff retention

Gergana Young
Level: Beginner
IoT, one of the biggest buzzwords of our time. What does this world of “things” mean for people who create software? We are not the people who are good at connecting the wires and components and we really don’t want to have to worry about that little bit of static electricity that can blow up that fancy microchip.
In this talk, I would like to show you how we can write good quality software to connect devices. How we can use cloud providers to collect and analyse data from different devices. How we can take the multitude of devices that already exist and make them smarter. In this way, we can use the skills we already have to do things that were not possible without IoT. We can create software that runs on devices and makes our lives and the lives of others easier.
Let’s talk about where the software fits in, or as I like to call it, the “I” in IoT.
In this talk, I will cover some of the histories of the Internet-of-Things, where the phrase came from and how it became such a big buzzword. I will then show some examples of IoT devices and how the more popular these “things” become the easier they are to build and use. There will be some hardware examples to emphasize this.
After this, I will go onto showing some of the code used to program these devices and how you can use the cloud (in this case Azure IoT Hub) to collect and analyze your data. I will also show how we can program devices to communicate with the internet and each other.
This is not a buzzword talk, this is a talk about writing good software for devices.
In the last few years, we have had a number of IoT talks at different conferences and meetups. Most of these talks focus on the fun parts, building devices and how to program them. This talk will be slightly different.
Although I would still like this to be a fun talk, it will also contain a lot of information that software developers could use when putting into a situation where they are required to build devices for large corporate solutions. I think this is needed in order to understand why IoT is not just a buzzword people like throwing around. We need to understand it and where we fit into it.

Perceived performance is not only about fast page loads and delivering the content as early as possible. It is also about all the interactions happening on an already loaded page. Even some of the most popular UI patterns can be a cause of frustration. Understanding what is happening under the browser’s hood can help you delight users with a smooth experience and avoid potential performance issues. Let’s demystify the rendering process and look into possible optimisations in order to achieve the best experience after the initial page load.

Robert Bravery
Facial recognition has always been the domain of science fiction. But not anymore. The technology is now available for us to now enter the world of Sci-Fi. Our face is a unique, intimate reflection of who we are. It represents our identity, character, emotions, age. Our brains recognise different faces and their unique characteristics. Our faces are the primary point of contact, especially within the human race. Our emotions and facial expressions are part of every aspect of our lives - how we learn and communicate, how we understand one another, how we interact with each other. Yet in today's world of technology, our face and emotions are mostly absent from our digital interactions. Up until recently, it has been difficult for the average developer to write software that will recognise facial differences, facial aspects and even emotion depicted by facial expression. Can we write software in C# to identify a picture, identify facial objects such as eyes, nose, ears, mouth, hair, etc. and then identify emotion in that picture. The human face can create about 5000 expressions. Can Facial Detection Software understand those expressions and identify the emotion. Technology is now available for us to write software that will recognise and identify faces and facial objects, understand emotion, and predict a proximate age. This talk will explore how we can do that. We will write and demo software that will be able to recognise faces, identify the emotion. Time permitting we will use this to explore Facial Bio-metrics. We will then look at different use cases and see how this technology can be used.

Chris Dawson
As a developer, I was fascinated by this concept of usability, a seemingly magical quality that somehow makes a world of difference for the ones that use our product. I spent the first 10 years of my career as a dev, went through a phase as a TDD fanatic, then landed up getting into interaction design and user experience. I was able to teach myself about UX from mostly free resources I found online.
So, what is it like for a software developer to transition their career into doing UX full time? Experience design, like any other discipline in software, is one that can be learned by anyone who is willing to invest the effort. I will share why I decided to quit programming for a career in UX and a few insights about how designers and developers can work together more effectively from a shared understanding.
Chris currently heads up the UX/UI division at DVT, a full-service software consulting firm. He has over 15 years experience in software product development, in roles ranging from full stack web developer to mobile developer to product owner. Around 2016 he decided to switch from a career in dev to concentrate on UX design, to be equipped to narrow the usability gap in the products he's making.

Jaap Coomans
If you’re a regular conference visitor, you’ll probably have attended at least one talk about Apache Kafka. Mostly you get all the good stuff about the product itself, the high-level architecture and maybe some examples of a message-driven “Hello World”. But what does it really take to start using Kafka in your Java application? What do the API’s look like? What will it take for you to be able to send or consume a message? In this session, I’ll try to show as much of the reality of integrating with Kafka as possible in the form of some live coding. I’ll start from scratch and show you everything you have to do to make it work, both in Spring and in standard Java.
Jaap is a Java developer and architect for jstack with more than 10 years of experience in Java development in various environments.

Enrique Geldenhuys
Closures, generics, inheritance, functional programming, microservices, and reactive programming: what do all of these have in common? While they have powerful capabilities and varying levels of popularity, they also have the power to be abused and misused. In this talk I want to discuss the rise and fall of popularity for different programming concepts and paradigms. What some of them try accomplish and the benefits of them, but I also want to discuss how none of these paradigms are golden hammers, and how each of them have trade offs. This talk is aimed at all experience levels with a focus towards helping senior developers responsibly mentor juniors. I want to highlight how touting these programming concepts and paradigms to junior developers, without proper context, can quickly leave the code unmaintainable.
Enrique has been a programmer for over seven years. And as his name suggests, he speaks Spanish even though he is proudly South African, born and bred. He started off with Java and transitioned to C# recently. Although he misses Java, he enjoys hacking around in Python, and developing on the web.

Kevin Trethewey
“Reality is that which does not go away when one stops believing in it” - Philip K. Dick
There are deep patterns that play out again and again in our industry and it’s hard to notice them if you haven’t been paying attention for a while.
Innovative ideas synthesised in a particular context (for example TDD, Micro Services, XP or Scrum) are then generalised as they are more widely adopted until they become so abstract the ideas lose their effectiveness. Books are written on the abstractions. Industries spring up to profit on the popularity of the abstract ideas. They become context-free dogma. Small pockets of people start to ignore the dogma and focus on what works, starting the cycle again.
As a programmer since the late ’90s, I focused on what worked, and readily adopted ideas that were useful.
A decade or so later, as a coach and consultant, I frequently provided context-free general advice that was aligned to innovative ideas that had worked for me in the past but never seemed to have a particularly large impact for the people and teams I was coaching.
Today, as a technical leader I make and observe so many micro-decisions on an hourly basis that I’m growing a deepening understanding of why my coaching lacked impact.
After all this, what have I found Really Matters when creating software?
My answers might surprise you.
For some, they may also challenge your current way of thinking, but my goals for this talk is not to convert people to my viewpoint. I'm not selling anything. I'm hoping to bring some reassurance to people who intuitively see that much of today's industry dogma is wrong. That we've been focussing on the wrong thing, and that when I've shifted my focus to what matters in reality, great things have happened.
Some key talking points I plan to traverse...
* Detecting (and avoiding) dogma * The importance of core communication skills in software development * The impact of separating decision making from doing the work * How mindset affects people’s realities, and the micro-decisions they make * The difference between changing reality and changing the perception of reality * How leaders at all organisational levels set the tone for context and its interpretation * Organisational structures and the behaviour patterns they generate * The problem with training/certification * Approaches to change that work
Over the course of his professional career, Kevin has had the opportunity to work in and observe projects, teams and organisations in vastly different environments, and seen vastly differing levels of success amongst them.
Through extensive coaching, consulting and business ownership experience he grew a deep appreciation for the values, principles and practices that are required for healthy, effective working environments.
Today Kevin has his sleeves rolled back up again and is leading an engineering effort that is creating a groundbreaking fintech product as part of an amazing international team at Jemstep by Invesco.

Offline capabilities are not normally associated with web applications, but the latest advancements in web technologies enable the development of a web application that can function regardless of the network state. In this talk, I’ll show you how we created a truly offline-first progressive web application by using modern web technologies such as Service Workers and IndexedDB.
You will learn what progressive web applications are, which characteristics make them behave and feel like mobile applications and why we chose to develop one for our client. I’ll also show you some of the techniques we used to ensure optimal performance regardless of the amount of data that was stored, what the network conditions were like, and what device it was running on. We will also cover some of the sync mechanisms that made the application fully functional even in the most remote areas of South Africa. Lastly, we will have a look at the upcoming advancements in web technologies and how this will further enhance the development of next-generation web applications.
This talk is applicable to audiences of all levels.

In this, no holds barred down introduction to Software Defined Radio (SDR) you'll learn how you can download data directly from various satellites in low earth orbit with nothing more than a cheap USB dongle and a makeshift antenna.
Our first target will be US National Oceanic and Atmospheric Administration (NOAA) series weather satellites to give us live image data of what the earth looks like from about 850km overhead.
If you thought your WiFi signal was bad, you haven’t seen anything! SDR USB dongles are cheap, readily available and can listen in on a wide range of the radio spectrum. However, they need a bit of help picking up the 137MHz signal from these satellites, so we’ll be building an antenna capable of picking up these signals.
With that setup, we’ll take you through some of the SDR software needed to analyse and record the signal (SDRSharp, CubicSDR or GQRX). Then we’ll look into how weather satellites encode image and telemetry data, and how you can decode it with a bit of Digital Signal Processing (DSP) software.
Next, we’ll target Russian Meteor M class satellites, and see what we can get out of those with some other techniques.

Do you ever feel that the fire inside you has burned out?
Burnout is a prevalent issue among IT professionals. A recent Blind survey shows that an average of 57% of employees from 30 tech companies reported burnout.
People in the IT profession are especially prone to burnout due to high job demands manifesting in a variety of forms, such as high mental and emotional load and frequent irregular working hours or excessive amounts of overtime. This in combination with environmental factors such as trust in leadership, alignment in values and communication all contributes to factors that can lead to burnout.
Some of the dangers of burnout are that it is not always easily identifiable and may not necessarily be limited to jobs requiring long working hours. Additionally, a person may not always be aware that he or she is experiencing it. With one of us have spent 15 years working in the IT industry and the other being a registered Industrial Psychologist, we as a couple have personally experienced and had to deal with the impact of burnout more than once in our lives.
We, Tanya and Riaan, would like to share our experiences as well as equip the audience with some tools for identifying, understanding, preventing and dealing with burnout.
Tanya is a registered Industrial and Organisational Psychologist with over 13 years’ experience in Human Resources and 5 years’ experience in the field of Industrial Psychology.
She worked in different industries including banking, investments, stockbroking, retirement fund administration, manufacturing, retail and short-term insurance. During her career, she developed a passion for the IT industry and community. She has extensive experience in dealing with employees, line managers and people in senior management.
She enjoys facilitating change on an individual, team and organisational level. Her "why" is to make the workplace a better place for everyone.

Many developers are under the mistaken impression that Kotlin is just for the Android platform. However, more and more developers are starting to use Kotlin for web backends and even frontends.
This talk will touch on the most popular language features of Kotlin. However, the bulk of the talk will consist of demonstrating that Kotlin can and should also be used for full-stack web development. I will take the audience through the development of a web app using Kotlin/JVM on the backend and Kotlin/JS on the frontend, using Spring Boot and React respectively.
Pamela is a second-generation coder and holds a BSc IT and BSc (Hons) Computer Science from the University of Pretoria. She has more than 15 years of experience writing desktop, web and mobile apps. She loves talking about Kotlin, ask her anything!

One evening, my little sister asked me for help with her homework at 9pm. She had already asked her classmates on a WhatsApp group, but nobody was able to help as all her peers had the same limited resources available to them. This gave me the idea for Buza (Zulu for “ask”), a platform for high school learners to ask questions that could be answered by volunteer university students in their free time. Buza is the first side project of mine that I’ve ever truly wanted to deploy. After months of coding and adding loads of features, I finally reached out to a senior developer to help me deploy my truck of features. The first thing she said was “A lot of this code will have to be replaced with production-ready code”. These are words you never want to hear.
University Computer Science equipped me with the ability to write code to solve problems, but in industry extra skills were required to build production-ready software. This talk will share the valuable lessons I learned from getting this Django web app production-ready. This will start with how to choose the right tools, framework, environment for your project. I will also cover how to set up testing and continuous integration for your project.

JavaScript is weird. It is a product of its failures as much as its successes. As a language, it is both modern and outdated. Cross-platform, yet not. Interpreted, but can be compiled. Loved, yet reviled. 'Good' JavaScript written a year ago looks very different to what one might write today, never mind code written 10 years ago. Every year a new set of features is ratified into the ECMAScript standard and is rolled out by browser manufacturers. This continual evolution can be frustrating and confusing but provides us with a unique opportunity. To embrace change, unlearn what we take for granted, and fall in love with JavaScript (again).
This talk will attempt to (re)introduce this contrarian language, addressing novices and veterans alike. It will make fun of JavaScript's foibles, mitigate its faults, and emphasize its strengths. It won't attempt to divorce it from context but will show which parts of the language you can use and when you should use them.
Mike Geyser is a Google Developer Expert in Web Technologies from Johannesburg, where he works in the R&D team at a company called BBD. He is a co-organiser of the Jozi.JS and Docker Johannesburg meetup groups and is a frequent technical speaker. He has been hacking on the web since Geocities was a 'thing', and has the keening wail of dial-up modem etched into his subconscious. While he is fluent in several ‘golden hammer’ programming languages, he has a long-lived love affair with JavaScript, and cannot see its (many, obvious) flaws. He has worked on lots of interesting enterprise applications, but it is the challenges of the public web that really appeal to him - having spent his formative years building transactional websites. He is always eager to talk about the web platform but be warned, he is prone to hyperbole.

William BranderThe only certainty in JavaScript is change. There is a new, cool framework popping up seemingly every week. jQuery, Knockout, AngularJS: all were once the darlings of the web, now relegated to the scrapheap of legacy. One day you will abandon your current favourite framework too, as it slowly falls out of fashion. How then do you choose an appropriate JavaScript framework? How do you make sure that the next framework is the one? Better still, how can you work with your favourite framework today, while still working within your legacy application?
What if you don’t have to choose the right framework? What if legacy never got in your way? Join me as I show you how you can take lessons from MicroServices and use them to let you work with new, exciting frameworks even in applications based on older, legacy, technology (no microservices required)
A professional geek, William works for Particular Software writing amazing software like NServiceBus. Passionate about the web and security, he is engaged in a sordid love affair with JavaScript and spends most of his free time trying to convince others of its beauty and elegance.

Justin SlackIt doesn't seem so long ago that front-end developers were employing all manner of techniques to use more than just the set of fonts installed on the user's computer. Now we have @font-face, OpenType features, WOFF (a font format specifically optimised for the web), and variable fonts. These developments allow us to create rich typographic experiences. But these experiences come with a performance cost: web pages become bigger and heavier. That means slower pages and more data to load.
This talk will cover the intersection of beautiful web typography and performance. We'll discuss the history of fonts on the web, how to enable rich typographic features, and how to load web fonts efficiently. We will cover typography and how it affects reading, a history of @font-face in the browser, Open type font features - like ligatures, lining numbers, stylistic sets - and how to use them, font loading strategies for optimal performance, and the future of web typography, variable fonts.

Chris TiteWe use time boxed cycles, shorter feedback cycles and small defined outcomes to run software projects. Why not use this approach to mentor and grow staff?
Why do we subject our teams to a sterile and delayed feedback KPA / KPI approach in the tech industry, an industry that is growing and experiencing rapid change?
These are all questions that puzzled me.
Four years ago I started mentoring team members using an agile approach which was refined over time and with each iteration, it is now an accepted and valued practice on all my teams.
This is my story.
In this talk I'll unpack;
* The agile mentoring approach and the mentoring life cycle * The different personas and people patterns adopted in agile mentoring * The tools used to manage the process * The career framework applied * Lessons learned
Join me as I share a fresh approach to mentoring team members which ultimately results in;
* Higher job satisfaction and less burn-out among employees * More confident teams with focused learning outcomes * Higher staff retention

Claire WoodDid you know, a diverse team is 35% more likely to produce above-average results? From the science behind why diversity boosts performance, to why being the only woman in your project team is more of a problem than you might think, this talk takes a closer look at the realities of inequality in our industry, how each one of us has a role to play in the solution and what we should be doing to move our industry forward.
If you’ve ever wondered about how we improve diversity in software engineering, or if you’ve never wondered, then this is the right room for you.
Twenty years in the industry, fifteen of which as a hiring manager, seven at board level, four as a reformed unicorn (you’ll have to attend to hear that story) has given Claire a fairly well-rounded view of where we’re still going wrong with equality in software engineering and made her an enthusiastic champion of improving gender parity in STEM education.

Jaap CoomansIf you’re a regular conference visitor, you’ll probably have attended at least one talk about Apache Kafka. Mostly you get all the good stuff about the product itself, the high-level architecture and maybe some examples of a message-driven “Hello World”. But what does it really take to start using Kafka in your Java application? What do the API’s look like? What will it take for you to be able to send or consume a message? In this session, I’ll try to show as much of the reality of integrating with Kafka as possible in the form of some live coding. I’ll start from scratch and show you everything you have to do to make it work, both in Spring and in standard Java.

Madene MaraisOffline capabilities are not normally associated with web applications, but the latest advancements in web technologies enable the development of a web application that can function regardless of the network state. In this talk, I’ll show you how we created a truly offline-first progressive web application by using modern web technologies such as Service Workers and IndexedDB.
You will learn what progressive web applications are, which characteristics make them behave and feel like mobile applications and why we chose to develop one for our client. I’ll also show you some of the techniques we used to ensure optimal performance regardless of the amount of data that was stored, what the network conditions were like, and what device it was running on. We will also cover some of the sync mechanisms that made the application fully functional even in the most remote areas of South Africa. Lastly, we will have a look at the upcoming advancements in web technologies and how this will further enhance the development of next-generation web applications.
This talk is applicable to audiences of all levels.

Felix WuUnit Tests measure the quality and effectiveness of your production code. But ever wondered how effective and relevant your tests are? Meet Mutation Testing: Bugs, so-called Mutants, wrong return values, for example, are automatically inserted into your code to test whether your tests fail - if they do, the mutant dies, if they pass, the mutant survives. The higher the percentage of mutants killed, the more effective your tests are. In this talk, I will introduce the attendees to this relatively simple, but ingenious way of checking that your tests will spot malfunctioning code, and show some live mutation testing in different languages.
Felix is a 17 y/o Software Engineer from Germany. Besides school, he helps companies all around the world building their technical infrastructure as a part-time Frontend Consultant for TNG Technology Consulting. In his free time, he is an active Open Source contributor and the co-creator of the JavaScript snippet collection 30-seconds-of-code and a platform for tech interviewees called 30-seconds-of-interviews. He currently also maintains react-perf-devtool. When not coding, you can find him talking or reading about it, as well as advocating for Youth in Tech and organizing CSSFrankfurt. He also loves travelling, especially with his girlfriend, and playing basketball and frisbee, as well as hanging out with friends. Like many young people, he also loves going to parties!

Matt CavanaghWelcome to 2019: You Twitch-stream your ironing, your car thinks it is smarter than you, and catapults have Wi-Fi!
We’re going to go through using game-engine physics simulations (because ALGORITHMS!) to design and optimize a small self-loading desk catapult design, then CAD’ing it for 3D printing, and finally hooking it up to an Arduino to control from a phone over Wi-Fi.
This isn’t your grandfathers' catapult! (Unless you give it to him, I guess?)
Matt Cavanagh is a developer from Durban who hates writing bios in the third person. He started a company called roguecode making Windows apps, but then decided to be poor was a better idea so went into game development. He’s done talks at conferences like DevConf, and TechEd (when Microsoft still knew SA existed).
Liam NormanLevel: Intermediate. In this talk, We will focus on how to split up an old enterprise application which has become a monolith into microservices. We will examine the pros and cons of doing so and also the best design practices and architecture decisions that will ensure this process is a success.
We will mainly explore how to identify services in your monolithic application, identify seams in your monolith. We will also investigate how to decouple microservices from monoliths and the best practices when doing so. We will also focus on microservices development and DevOps such as scalability, load-balancing monitoring and reliability.
We will be examining how to extract a monolith application using example PHP/Laravel microservices that were pulled out of a larger legacy Laravel application. I will also investigate some war stories on how Superbalist achieved this and the lessons learned along the way.
At the end of the talk, you will know better how to refactor your monolith and improve your own architecture.

Ryan KotzenSo many aspects make up being the best developer you can be yet we tend to focus almost exclusively on the obvious ones like learning the next library, framework or methodologies. Here we will explore some critical practices you may be missing that will not only improve your craft but your life. Our industry moves fast, there are new libraries and frameworks created every day, not to mention all the updates and features added to the ones we already use and love. There is a constant drive to deliver more, to increase velocity, to meet and exceed deadlines. We celebrate the culture of “being totally swamped” and wear it as a badge of honour. Impostor syndrome is real and can make us feel like we have to keep up with everything and it’s just simply not possible to do so. We don’t let this simple fact stop us from trying and we make bad trade-offs that are actually detrimental, leaving a trail of destruction through our bodies, our minds and sometimes even our family and friends. What if I told you that the world you live in is a prison for your mind, that it doesn’t have to be that way? As The Oracle told Neo, you will have to make a choice. There are techniques that will allow you to lead a better life, some you may already know but just don’t practice and some may be more esoteric. In this talk I will be distilling the years of self-help research and practice that I have personally gone through to show you how you can improve the quality of your life, not just to make you a better, more effective developer but a happier more grounded person. Naturally, as we are all in the tech field, I will be showing you some really awesome tech solutions to help you on your journey.
Some of the topics we will be looking at are:
Ryan Kotzen is an aspiring stoic, essentialist, polymath, polyglot software engineer, and armchair philosopher. Ryan is a believer in constantly evolving and evaluating what you are doing, utilising concepts from lean, kaizen, XP and the agile manifesto to name a few. Ryan has a passion for coaching and learning from other people. When not developing software, Ryan likes to spend his time airbrushing, geeking out on a geeky movie/series/book, playing Kerbal Space Program and all aspects of the Warhammer 40k hobby.
Robert BraveryFacial recognition has always been the domain of science fiction. But not anymore. The technology is now available for us to now enter the world of Sci-Fi. Our face is a unique, intimate reflection of who we are. It represents our identity, character, emotions, age. Our brains recognise different faces and their unique characteristics. Our faces are the primary point of contact, especially within the human race. Our emotions and facial expressions are part of every aspect of our lives - how we learn and communicate, how we understand one another, how we interact with each other. Yet in today's world of technology, our face and emotions are mostly absent from our digital interactions. Up until recently, it has been difficult for the average developer to write software that will recognise facial differences, facial aspects and even emotion depicted by facial expression. Can we write software in C# to identify a picture, identify facial objects such as eyes, nose, ears, mouth, hair, etc. and then identify emotion in that picture. The human face can create about 5000 expressions. Can Facial Detection Software understand those expressions and identify the emotion. Technology is now available for us to write software that will recognise and identify faces and facial objects, understand emotion, and predict a proximate age. This talk will explore how we can do that. We will write and demo software that will be able to recognise faces, identify the emotion. Time permitting we will use this to explore Facial Bio-metrics. We will then look at different use cases and see how this technology can be used.
Robert has been in the IT and Development game since the 1980’s. His first computer was a Sinclair ZX Spectrum with 48K ram. Robert has developed code in more than 16 different languages and scripts. He has a passion for software development, designing and delivering the right software in time with as little defects as possible. Robert likes to be at the cutting edge of technology. From the very beginning, modifying an IBM Brother XT PC into the fastest PC around to the latest in AI. Robert has seen tech come and go and in most cases forgotten what others have not yet learnt. Robert is a manager and Senior Developer at IQ Business.
Chris DawsonAs a developer, I was fascinated by this concept of usability, a seemingly magical quality that somehow makes a world of difference for the ones that use our product. I spent the first 10 years of my career as a dev, went through a phase as a TDD fanatic, then landed up getting into interaction design and user experience. I was able to teach myself about UX from mostly free resources I found online.
So, what is it like for a software developer to transition their career into doing UX full time? Experience design, like any other discipline in software, is one that can be learned by anyone who is willing to invest the effort. I will share why I decided to quit programming for a career in UX and a few insights about how designers and developers can work together more effectively from a shared understanding.
Chris currently heads up the UX/UI division at DVT, a full-service software consulting firm. He has over 15 years experience in software product development, in roles ranging from full stack web developer to mobile developer to product owner. Around 2016 he decided to switch from a career in dev to concentrate on UX design, to be equipped to narrow the usability gap in the products he's making.

Kevin Trethewey“Reality is that which does not go away when one stops believing in it” - Philip K. Dick
There are deep patterns that play out again and again in our industry and it’s hard to notice them if you haven’t been paying attention for a while.
Innovative ideas synthesised in a particular context (for example TDD, Micro Services, XP or Scrum) are then generalised as they are more widely adopted until they become so abstract the ideas lose their effectiveness. Books are written on the abstractions. Industries spring up to profit on the popularity of the abstract ideas. They become context-free dogma. Small pockets of people start to ignore the dogma and focus on what works, starting the cycle again.
As a programmer since the late ’90s, I focused on what worked, and readily adopted ideas that were useful.
A decade or so later, as a coach and consultant, I frequently provided context-free general advice that was aligned to innovative ideas that had worked for me in the past but never seemed to have a particularly large impact for the people and teams I was coaching.
Today, as a technical leader I make and observe so many micro-decisions on an hourly basis that I’m growing a deepening understanding of why my coaching lacked impact.
After all this, what have I found Really Matters when creating software?
My answers might surprise you.
For some, they may also challenge your current way of thinking, but my goals for this talk is not to convert people to my viewpoint. I'm not selling anything. I'm hoping to bring some reassurance to people who intuitively see that much of today's industry dogma is wrong. That we've been focussing on the wrong thing, and that when I've shifted my focus to what matters in reality, great things have happened.
Some key talking points I plan to traverse...
* Detecting (and avoiding) dogma * The importance of core communication skills in software development * The impact of separating decision making from doing the work * How mindset affects people’s realities, and the micro-decisions they make * The difference between changing reality and changing the perception of reality * How leaders at all organisational levels set the tone for context and its interpretation * Organisational structures and the behaviour patterns they generate * The problem with training/certification * Approaches to change that work
Over the course of his professional career, Kevin has had the opportunity to work in and observe projects, teams and organisations in vastly different environments, and seen vastly differing levels of success amongst them.
Through extensive coaching, consulting and business ownership experience he grew a deep appreciation for the values, principles and practices that are required for healthy, effective working environments.
Today Kevin has his sleeves rolled back up again and is leading an engineering effort that is creating a groundbreaking fintech product as part of an amazing international team at Jemstep by Invesco.

Gareth StephensonFor my Masters degree research project, I chose to perform a controlled experiment with a group of volunteer software developers. The experiment was to test the theory that Mob Programming positively affects team communication and learning, compared to working in a self-organised team formation. One requirement of the experiment was for the volunteers to complete a "Big Five" personality traits assessment, to see how they scored against the traits of Openness to Experience, Conscientiousness, Extraversion, Agreeableness and Neuroticism.
The data collected from the assessment, along with the answers from the questionnaire at the end of the experiment, provided some valuable, quantitative insight that could be of great value to anyone who works in a software development team.
In this talk, I present the findings of the experiment and what it could mean for you and your team.
Gareth has spoken at various conferences and user groups throughout South Africa on topics ranging from software development to building cluster-computing systems using Raspberry Pi's. He's been working in the software development field for over 20 years, and he's still no good at it.
Karl FischerWhere Test-driven development and Infrastructure as code have a love child.
Everything around you is made up of atoms, DNA or code, there is a recipe on how everything is put together, and like most things... as soon as things get created organically it gets messy. With the advent of composable infrastructure or infrastructure as code, we need to focus more on getting reproducible systems as opposed to a patchwork of chaos. Using Test Driven techniques we can create and implement reliable, repeatable infrastructure.

Gerard de JongIn this, no holds barred down introduction to Software Defined Radio (SDR) you'll learn how you can download data directly from various satellites in low earth orbit with nothing more than a cheap USB dongle and a makeshift antenna.
Our first target will be US National Oceanic and Atmospheric Administration (NOAA) series weather satellites to give us live image data of what the earth looks like from about 850km overhead.
If you thought your WiFi signal was bad, you haven’t seen anything! SDR USB dongles are cheap, readily available and can listen in on a wide range of the radio spectrum. However, they need a bit of help picking up the 137MHz signal from these satellites, so we’ll be building an antenna capable of picking up these signals.
With that setup, we’ll take you through some of the SDR software needed to analyse and record the signal (SDRSharp, CubicSDR or GQRX). Then we’ll look into how weather satellites encode image and telemetry data, and how you can decode it with a bit of Digital Signal Processing (DSP) software.
Next, we’ll target Russian Meteor M class satellites, and see what we can get out of those with some other techniques.
Gerard holds a Master’s Degree in IT from the University of Pretoria, is a member of [Mensa](mensa.org.za) and has consulted for the likes of Standard Bank, Nedbank, MTN, De Beers & Experian. He’s also worked on both the FNB and Barclays (Absa) mobile banking Apps on the Apple iOS platform.

Rory PreddyMy life is a hilarious roller coaster of miss-intended programming bugs because at 4 foot tall and 65 kilograms I completely fall off your radar.
What did my scale call me! Why does facial recognition see me as a child? These are all valid questions I often ask myself as I navigate my weird and different world. Have you heard the phrase “You have to be this tall for Micro-services”? well, what about: “You have to be this tall to operate a mobile phone?”. I am finding it harder and harder to reach any button except for “#” and “9”.
Building accessibility into the planning stages of programming can eliminate barriers for participation and create an inclusive environment for people with disabilities. Programming for diversity serves as an unquestionable indicator that your software embraces the diversity of your users and cares about their safety and comfort.
Join me on a fascinating and thought-provoking look at how you can program for accessibility.
At 124 centimetres (or 4' 1") tall, Rory's life is a hilarious roller coaster of miss-intended adventures and challenges. Rory is lucky enough to work full time in R&D and an organizer for the Jozi-JUG and AWS-Jozi. He spends his time between enabling developer communities and his overly hyperactive wife/kids/dogs.
Sewagodimo MatlapengOne evening, my little sister asked me for help with her homework at 9pm. She had already asked her classmates on a WhatsApp group, but nobody was able to help as all her peers had the same limited resources available to them. This gave me the idea for Buza (Zulu for “ask”), a platform for high school learners to ask questions that could be answered by volunteer university students in their free time. Buza is the first side project of mine that I’ve ever truly wanted to deploy. After months of coding and adding loads of features, I finally reached out to a senior developer to help me deploy my truck of features. The first thing she said was “A lot of this code will have to be replaced with production-ready code”. These are words you never want to hear.
University Computer Science equipped me with the ability to write code to solve problems, but in industry extra skills were required to build production-ready software. This talk will share the valuable lessons I learned from getting this Django web app production-ready. This will start with how to choose the right tools, framework, environment for your project. I will also cover how to set up testing and continuous integration for your project.

Helge ReikerasIn this talk, we'll dispel the common myth that you need a room full of PhDs to implement data science and machine learning into your software product. We'll present data science and machine learning as another tool that everyone involved with building software should have in their toolbox. We'll talk about the concepts, tools, and resources that a software developer needs to get familiar with, the value that data science and machine learning can bring to a software product, and how to get started doing it yourself.
Helge is a data scientist with 6+ years of experience in the practical implementation of products and services across a multitude of industries including insurance, banking, retail, and human resources. He is currently a data scientist at Offerzen.

Marco Heimeshoff We build software that changes the world. From optimizing small companies to connecting humans and businesses on a global scale, our work plays a hidden but major role. Software development is not about software, it is about understanding the customers domain and solving their problems. We need a culture, a way of thinking about the needs of the customers first and putting an emphasis on their language and human interactions. If we let the domain drive our design, we can tackle complexity in the heart of software. The pillars of Domain Driven Design are learning, language and empathy. With the right mindset it becomes simple to derive good models, keep them pure and aligned with the business. Simple is not easy, but done right Domain Driven Design transforms everything in your organisation: code, culture, agile and architecture.10h00 → Movement, Networking, & Snacks ← 10h30
Melissa Landsberg
With this talk I would like to discuss what a full stack developer is and how this can lead us to be better at our craft. This is not just a definition, but a dedication and conscious decision for any developer to become good at what they do. For a junior to become involved in all aspects of a team, they have to go through a journey. A journey that involves different technologies, methods and experiences that make people's lives easier with our code. Is this not what programming is all about?

As a very independent person she is able to earn her keep - enhancing her ability to generate returns for her employer and clients. She is always aware of the expectations paying customers have for quality work delivered with minimum fuss. Her quick intellect, sense of humour and natural empathy garner co-operation and support from colleagues and clients alike. She is a forceful personality who likes to make a difference and take the lead.
Rouan Wilsenach
Like it or not, things will always go wrong in production. Rouan is going to tell you about the types of issues that you should expect. He’ll show you a range of techniques for finding out quickly that something has gone wrong, including everything from automated alerting to an old-fashioned phone call from a grumpy user.
Rouan will also cover diagnostic tools that can help you figure out what went wrong, talk about how your team could approach issues, and explain the possibility of creating self-healing mechanisms. Lastly, he’ll chat about what you need to ship a fix fast and how the right production monitoring can even help you write less code.
After attending the talk, you’ll see that production issues are learning opportunities. You’ll be ready to spot them, understand them and use them to build better software.
Rouan Wilsenach is a software developer. He has built applications in a variety of technology stacks for companies in the financial services, education, health and media sectors.

Tim Lewis
The JAMStack is a new way to approach creating a website or web application. In the past if you wanted to get something online, you’d have to spin up a server that was always online. If you wanted to keep costs down that server would have to be small, but that meant you couldn’t handle large traffic. If you wanted to scale cost-effectively, that meant you’d have to use someone else’s platform, which meant you lost some control. JAMStack allows you to create full websites that are fully delivered via CDN, but without losing functionality.
I’ve used JAMStack to create a personal blog, a corporate publishing platform, landing pages and product MVPs. The JAMStack is a very flexible tool that allows you to get your content in front of people, easily. Youre site consists made up entirely of static resources, that can be delivered through a CDN. If you need more processing, you can then offload those to ‘hosted functions’ like AWS Lambda, Azure Functions or the like.
In this talk I’ll walk through the details of the JAMStack, creation of a site, how to deploy one and building in features like search and more complex functionality.

Terence Kruger
In this talk, I’ll take a deeper dive into graphing, what it can do, where to use it and where not to. Allowing you to add it to the tools you already have in your toolbox. We’ll take a look at graphs and the tooling in today’s world that allows us to make use of graphs in different ways. I’ll be doing a lot of demo’s along the way. Talk outline:
Working in both agile and not-so-agile teams over the past 13 years. With the word agile meaning so many different things Terence strives to bring an attention to the principles and allow teams and individuals to reach beyond their own expectations. Terence appreciates, and shares with listeners, that bringing change to their teams is a moment-to-moment choice and not about positions or titles. Passionate about helping developers grow and share their experiences by helping build a better developer community.
Monorepos are a controversial idea and many think that they are bad practise. However, large companies like Facebook are actively using them to manage their projects. I will build a case for monorepos from first principles and share lessons learned while working on large digital transformations.
A walk though of my journey as a Business Intelligence developer who wanted to get started with Windows 10 IoT development on a Raspberry Pi 3 with no C# skills. The talk will go through some of the practical challenges and benefits gained from the process.
Arohan is a Business Intelligence developer working at Entelect primarily on the Microsoft BI stack who has an interest in using Big Data and IoT to find insights into ways to improve daily life as well as focused research on using technology to enhance learning.
Usage of any tech product on a regular basis creates habits among its users. Habits are created spontaneously without the user noticing it. If these habits are not carefully thought out (and the product specifically designed to drive certain habits) user habits can get out of control. This talk will give you some insight into the concept of habit driven design (HDD). How does the products we use daily dictate our habits? Why is it important to design for specific human behavior? Come and challenge yourself as we journey into the world of user habits and software.
Nico is a software engineer at Entelect. In his free time he likes to play around with random tech. During long train rides to work he likes to enrich himself with reading philosophy. He is fascinated by the psychology of user behavior, especially when software is involved. When he grows up he wants to be a writer.
Amy Codes
Kubernetes has become the de-facto standard for container orchestration today. However beginner-level educational content to learn Kubernetes today is still focused on cluster management through the Kubernetes CLI tool. This can make it harder for novices to visualize the relationship between the commands they’re issuing and what’s happening in the cluster. Incrementally building a Helm Chart provides an easier, more intuitive, and more visual way of learning the key concepts of Kubernetes, while addressing how to manage package releases upfront.
This talk will cover how to incrementally build a Helm Chart for NGINX, and along the way, will cover key Kubernetes concepts. Content will include as many diagrams and visuals as possible to accompany these concepts, and include how to deploy the new NGINX chart from a Kubernetes cluster.
Amy Chen is a software engineer at her Heptio. She is passionate about open source, containers, orchestration tools, Go, and salsa dancing.

The tech landscape is changing faster than ever, and this trend is only accelerating. How do technical people grow when the world is changing faster than you can finish your next cup of coffee? How does one keep up? What should you learn? Are there things we can focus our learning efforts on besides just the next tech flavour of the month? This talk will explore some areas of learning that technical people might not intentionally consider. These areas focus on higher-level concerns, with slower rates of change, which can help technical people develop into more well-rounded individuals.
Janco is a software craftsman on a lifelong journey of understanding the fundamental nature of software development. He spends most of his time building stuff he hopes will add value to someone’s life, while coaching, mentoring and journeying with fellow software craftspeople.

Developing Android Apps has notoriously been a difficult task. Previously, Google refrained from giving advice as to how you should go about architecting your Android applications and it has been “left it up to the reader” to decide how. This lead to apps having a lot of bloat in their activities and being really difficult to test. This has now changed since Google I/O 2017 where the new Android Architecture components were introduced. The libraries aim to make developing and maintaining your Android apps a lot easier. In this presentation, Rebecca will present the components and dive into detail around the different types of tests you should write (and where) for your newly architected Android application.

Technology needs to break down bearers to productivity. The future of .net standard has the potential to do so. Having seen the latest strides that Microsoft has been doing with .net standard, it is getting clearer that with the development tools available from Microsoft we as developers can with ease build products that enables developers to target more platforms at a faster pace.
.net standard gives developers a wider access to .net API’s and I will show how this library can rule them all irrespective of the platform. I will also outline how .net standard compares with .net core, .net framework and xamarin
Griffiths Sibeko, a lifelong learner with a grade zero mentality who draws his design inspiration from nature, human interactions and communication patterns.
Learning how to use a computer at the public library at age 11 where the staff was always sceptical that he would break the equipment, he got to excel at using computers and got his first promotion from owning a library card to owning a library staff card. He later then realised his passion to design and develop solutions to help better ways in which people interact with the world around them.
Some of the accolades that Griffiths has achieved include winning the 2014 MTN Best Garage Developer competition, in 2016 Griffiths was featured in Forbes Africa for some of the sacrifices he had to make to pursue a career in software development. Currently Griffiths leads the Windows client team at Zapper.
Peter Wiles
What does it mean to be a “professional” software developer? It means a lot more than just writing code for money. At Chillisoft we have been discussing what this means over the past few years, and we have even taken it to the point where we have started up a School of Professional Software Development, called DevFluence. We sum up the status of being a professional software developer in this phrase: "The courage to create value for customers, myself and my community." In this talk, I want to explain what we mean by this phrase, and then provide some examples of young developers who are doing this. I also want to talk a bit about DevFluence and how we are trying to spread this ethos while building technical skills in South Africa.
Peter is a software developer that loves to think about the broader aspects facing software developers and the industry itself. Languages and algorithms were his first love in coding, and in the 18 years since beginning a career as a developer his interests have expanded to include business problems and industry-wide challenges in South Africa.

Bots, AI and Cognitive learning is going to change the way we life, how we think and how we work. It will also change how we code and how we analyse data. Automated and driverless vehicles are one example of software bots and mechanical robotics interacting. Deep learning and Natural Language Processing (NLP) will make it possible to ask virtual bot assistants questions in a natural way and get meaningful answers. Analyzing huge amounts of text, social media posts to understand sentiment and thought process will be a huge advantage to business and even government. Face-recognition and photo-analysis at the hands of the populous makes searching and analyzing digital data easier smarter and more accurate. Lear how we can make use of Bot Frameworks, AI Frameworks and Cognitive Frameworks that are available today to achieve what we might have thought previously impossible or event at the least out of our reach.

Facebook did something beautiful when they built react. The combination of reactive programming, functional programming and immutable data has truly taken the web by storm.
What does it look like when you’re using a simple programming language, and powerful toolchain, that enshrines these values to build your next react app? What if you don’t need to have these conflicting ideals in one code base?
re-frame is a framework around a wrapper over react and gives developers a simple deterministic way to deliver rich single page applications. Being impressively buzzword compliant, it brings together the best of react, redux, Elm and other ideas that have taken the SPA world by storm. re-frame delivers a data oriented approach to designing and building your next application.
ClojureScript is an implementation of Clojure that targets JavaScript runtimes, both browser and Node. ClojureScript is a dynamic functional language with an impressive toolchain that is the envy of any developer that has seen it, but can’t use it. You get true hot code reloading, advanced optimisations thanks to Google’s Closure Compiler, the safety of immutable data, the flexibility of dynamic typing, and great JavaScript interop, all packaged up in a wonderfully simple experience. ClojureScript does not shy away from the fact that it gets compiled down to JS, instead it offers all the escape hatches you’d ever need to interop seamlessly and build on the work of other developers.
Kenneth is full stack web developer with nearly 20 years under the belt. He's currently enjoying the revitalizing experience of writing Clojure and valuing values. Outside of his day to day, he maintains and contributes to several open source projects, writes on his Open Sourcery blog, co-hosts the ZADevChat podcast and enjoys speaking at local meetups and conferences. He enjoys learning and sharing, meeting and connecting people and being involved.
Daniel Irvine
The idea of mentorship is strongest within the software craft community, which values the idea of apprenticeship. But the concepts within the apprenticeship model are valuable to all technical mentors, not just those who hire apprentices. Knowing how to give feedback, having a set of coding exercises, regular planning and estimating are all invaluable skills. In this talk I’ll look at these and other ideas for how to ensure you give your mentees the best chance of success.
Daniel is a software consultant based in London. He's a member of the software craft community and a founder and organizer of Queer Code London.

Log files hold a vault of useful information for operations as well as business.
Processing your log files could reveal a host of useful information.
Join me for a hands-on presentation, where we’ll pull some useful open source Docker containers and set to work making them weave some magic on our log files.
We’ll cover some Docker Compose basics to get you started with a simple ELK stack (Elastic Search, Log Stash and Kibana), configure some endpoints and setup log shipping (for Linux and Windows) so that we can process log files.
Once we’re processing logs, we’ll look at ways to transform and embellish our log data to add IT operational, as well as business value.
Using our transformed data, we’ll also cover visualising the data using Kibana.
To close out we’ll also consider alternative technologies such as Prometheus and Grafana, and discuss the pros and cons of the different technologies.
Mining log files has never been so simple.
Join me to see how easy it is to get started.

What is the cost of our culture's addiction to software? How much fuel is needed to produce enough power to keep that docker container running? I'm no bunny-hugger, but I'll share some of my research and conclusions on a cause many of us don't think about - the environmental impact from our insatiable need for software, and what we as developers can do to help. Don't miss it.

In this talk we’ll explore the Kali Linux toolset and show you how to break into a WPA2 secured wireless access point.
First we’ll take you over how to capture a wireless client’s handshake, then we’ll show you how extract the hashed passphrase and finally how to crack that hash to reveal the passphrase itself.
As a side act we’ll also show you how to jam wireless networks and even target specific users.
You’ll will leave this talk with a deeper understanding of the problems with our current 802.11 WiFi standards, why cracking them is much harder to pull off than you would have thought, and hankering to change your WiFi password then you get home!

Users always rely on downloading mobile apps that could serve them when they are offline or have poor internet connections. This is because most mobile apps still offer amazing user experience when there is no connectivity. Unfortunately, users are sensitive of the apps they download so as to keep their resources in check. If your app can’t compete enough with apps Facebook and Whatsapp, it might end up dying out in App stores.
With Service Workers and Manifest JSON files, we can build engaging web app user experience even for offline users. We’re talking notifications, installable, fast, offline usage, complete app-like experience, etc. Now that the support is almost in all browser is the best time to start giving our users fantastic experience as web developers.

Brendon Page
The building metaphor that is so often applied to software development is broken. Why do we need to start with the foundations first? The roof we’re building is virtual, it can float! So why not build it first? Or even better just the part that we need first.
We’re so used to building software from the bottom up that we don’t even realise that it involves an incredible amount of guess work and ultimately results in a lot of hidden waste. In this talk I examine and challenge current thinking about the order in which we build software, thinking which I believe has been perpetuated by the building metaphor we use when we teach new software developers and when we communicate with non-developers in the industry.
Brendon is passionate about writing software, in a sustainable way, that solves real problems. He is an avid TDD’er, loves teaching and spends a lot of his spare time speaking at or running dev focused community events. Lately a lot of his thinking has been around how to be better at writing software with a primary focus on the thought process of the developers themselves.
Since the dawn of man (And indeed, Kerbalkind), we have looked up at the moon and stars and wondered ... is there cheese out there? Seeing as how modern science has yet to answer this question sufficiently we set out to see for ourselves.
In spaceflight people use physical switches, dials, buttons and readouts to pilot their vessels. In the game Kerbal Space Program you use a mouse and keyboard. In order to get a more authentic experience, we set out to build a KSP Control Board.
As you can see from some of the sample pictures, a few people have managed this before. However most of it is written using C# since that is what the game is written in. Because JavaScript is awesome, we set out to use that instead.
There is a mod for the game called KRPC which allows you to use Google Protocol buffers and WebSockets to communicate with the game remotely. We wrote a node.js module that can be included in any regular app. Using this module, and Johnny-Five we wrote a node.js script that can interface with the Arduino. The Arduino in turn interacts with the various physical switches, buttons, joysticks, sensors and a LCD.
In addition we wrote an auto-pilot script that is capable of doing SpaceX Falcon 9 style return to launch site mission using a script written purely in JavaScript.
Ryan Kotzen is a recovering enterprise developer. Ryan joined Entelect in 2009 fresh out of varsity (UJ) and has been there ever since. He has worked in a wide range of domains including fintech, health, employee and customer loyalty, gamification, event management, and retail. Ryan started his career in .Net and was part of the founding of the start-up Encentivize where he gained a wealth of knowledge about JavaScript and the MEAN stack. As an Engineering coach within Liberty dHub, Ryan has had an opportunity to deliver a mobile app written in React-Native and exercise his automation and DevOps skills, dabbling in Python, Ruby and GO. He has a passion for teaching and coaching others. When not developing software, Ryan likes to spend his time playing Kerbal Space Program and engaging in the Warhammer 40k hobby.
After spending some years dabbling and failing in the arts, Jake moved onto studying Electrical Engineering at the University of the Witwatersrand. Despite the big change in direction, he did well enough to graduate in 2014. By this point he knew he wanted to work with software, and was promptly hired by Entelect where he's been ever since. After spending some time as a .NET developer, Jake started to become interested in JavaScript as more and more of his work required it. Then one day, Ryan (Jake's co-presenter) sent him an image of someone's homemade Kerbal Space Program control board, and said "Hey, we should try something like this, but with JavaScript!". Thus began the work that lead to them presenting this contraption at the JSinSA conference, and now, at DevConf. When not coding, Jake can generally be found looking up at the stars, or playing some space themed computer game.

As members of the local technology industry, we are often bombarded with new jargon, new buzzwords, and new concepts from news and developments around the world. Artificial intelligence(AI), machine learning(ML), and neural networks(NN) all fall into that category of buzz words. This talk dives into the concept of neural networks. Neural networks are known as something used in machine learning, but few people understand how they work and the potential power of them. This talk includes how neural networks fit into AI, the historic inspiration, the intuition for how neural networks operate, the mathematical knowledge required for working with neural networks, the use cases for neural networks, and programming tools and frameworks that can assist one in developing machine learning applications using neural networks.
Rishal is currently fulfilling the role of a solutions architect at Entelect. He is involved in ideating, designing and developing solutions for various national and international blue chip clients whilst actively growing thought leadership capabilities within the company and tech community.

For years and years, network pen-testers have owned companies and networks with playbooks written in the 90’s. With a good mix of footprinting, scripting and unexpected interdependence, even moderately skilled attackers have been able to reign supreme without ever needing a 0day. How does this change as organizations slip more and more into the cloud? What do rootkits look like and what does lateral movement mean when its between different SaaS products? In 2009 we took an initial stab at answering some of these questions, and now we’re revisiting the topic in light of the huge strides made in cloud services.
We cover a few recent attacks on companies that leveraged cloud services, showing security failures can occur on the boundaries of, rather than solely in, services. We demonstrate easy and novel ways to embed compromise detection capabilities in third party services without requiring support in those services. We show how developers can be attacked with malicious code editor plugins. We tackle the gorilla, Amazon Web Services, revealing a series of attacks that cover reconnaissance, compromise, lateral movement, privilege escalation, persistence and logging disruption. Lastly, we end off describing how to aid compromise detection in cloud services.

The holy grail of web applications is having them be near-native performance, and to a large degree this has driven the JavaScript revolution. To truly realise that goal we need to embrace native design thinking for our applications, applying it not only to our code but also to our content. Using ideas from Progressive Web Applications and a modern framework such as Angular we can create engaging, fast and available application experiences - the best of both native and web.
This code-oriented talk will show how to practically use select principles of Progressive Web Applications in conjunction with Angular to create fast and compelling web experiences. It will cover the creation of an application shell and go into using service workers for preloading, caching and even offline support.
Mike Geyser is a programmer at BBD in the R&D team, co-organiser of the Jozi.JS meetup group, a frequent technical speaker, and loves the web. He has been hacking on it since Geocities was a thing, and has the keening wail of dialup modem etched into his subconscious. While he is fluent in several ‘golden hammer’ programming languages, he has a long-lived love affair with JavaScript, and cannot see its (many, obvious) flaws. He has worked on lots of interesting enterprise applications, but it is the challenges of the public web that really appeal to him - having spent his formative years building transactional websites. He is always eager to talk about the web platform, but be warned, he is prone to hyperbole.
While some home brewers consider automation to somehow make your brewing less “real”, part of the reason I brew is because I get to make stuff (I also happen to like beer).
In this talk I’ll very briefly go through the beer brewing process and explain what requirements I came up with for my project.
Then I’ll give you a very brief introduction into clean architecture before diving into how I used it to make my Android Things project simple, testable and extendable.
Along the way I’ll show you how you can run your IOT project on an emulator to help with debugging as well as testing.
Riaan is Technical Lead who develops mobile apps for Discovery by day and tries to find ridiculously interesting projects to tinker with by night.
His decade of work experience includes setting up an SMS service for USAID in Afghanistan, consulting on a mobile CRM system in Costa Rica and helping out with systems for an SMS campaign during presidential elections in Zambia.
In his spare time he likes to tinker with computer vision, robotics and home automation projects. There has been rumours of an obsession with all things beer related as well. This has led to talks on using Sci-fi interfaces as inspiration, using computer vision to keep physical and electronic scrum boards in sync, getting started with robotics using Javascript and building your own keyboard.
You may assume that software engineers are hired to write code. But this definition is too narrow to accommodate software engineers who are good at their job. Good in what sense? Well, the only sense that makes sense: good at helping their company succeed. And for a company to succeed, it must solve problems for its users. And so, we have it: good software engineers are good at solving user problems. Slinging code is but one tool to solve these problems. Getting stuck there does not bode well for your users, for your company, and for you.
Arjun loves writing code. So much so that he dropped out of university, to get his fix by founding a startup. That startup became kandua.com - a marketplace for home services that has brought millions of rands to little tradespeople, with investors in 3 countries.
This talk is a continuation of a series of talks I gave several years ago on the “importance of pet projects”. The intention is to encourage experimentation and fun outside of the day-to-day project work without promoting burn out. It will also highlight the potential for exposure - both from a marketing point of view and career.
The idea is not to push people to overwork outside of normal office hours, but instead to show the audience that we all have a fantastic skill and can use that to have fun with exposure being a nice potential side effect.

Deep Learning has the ability to disrupt and to disrupt fast. The democratization of AI has meant that algorithms and tools are mature enough to make a difference in almost any industry. The uptake of AI to augment our world will depend on the ability to interact with AI services in a familiar way. The recent agreement between Amazon’s Jeff Bezos and Microsoft’s Satya Nadella to integrate Alexa as a service in Cortana, and to integrate Cortana as a service in Alexa is a clear indication that the value is not in the assistant itself, but rather in the ability to connect services with people. I will use the demo to show you an effortless way to interact with a Computer Vision System that is aware of its surroundings using the Google Home Assistant.

William Brander
As developers we spend a lot of time structuring our systems just right. We make sure we select the right patterns, use the right combination of acronyms (CQRS + DDD + ES), and do all the right devops so that we can scale up/out/elastically. This adherence to best practices seems to fall apart at the front end though. We have separation on the back end, but on the front end this all needs to come together. How do we stop it from turning into a mess of spaghetti code? How do we prevent simple actions from triggering hundreds of web requests? Join William as he builds a .NET Core Composite UI from scratch.
A professional geek, William works for Particular Software writing amazing software like NServiceBus. Passionate about the web and security, he is engaged in a sordid love affair with JavaScript, and spends most of his free time trying to convince others of it’s beauty and elegance.

Oz Chihwayi
In this talk, we will introduce critical thinking; what is it and why it’s a critical tool for us as architects and deliverers of solutions? How can we add this to our daily tool box in order to improve our thinking in everyday situations? We will explore some practical steps to help us ask better questions, internalize feedback and make more sound judgements. How do our biases block our understanding , and how do we unlearn these in order to gain clarity of situations? We will also cover logical fallacies and unpack the key elements of an argument and tools that can help us enhance our arguments to optimize for better understanding and results.

The nature of applications is critical to what we want them to do - they can provide meaningful and even critical advantage to a business – they can connect people that were unable to connect with each other before – or provide a new and engaging way to interact with customers. In a fair number of online businesses their ability to interpret and understand what customer are doing and how they are using these services, all comes from a deep understanding and application of insights gained from the data that is gather. This ability and understanding is no longer the domain of Facebook and Amazons but is a necessity for all business to – understand customers better, then be able to respond appropriately and ultimately assist customers in being able to take the best advantage of what value the business has to offer. This all has to happen at a rate and scale beyond human intervention. Machine learning has the promise and already proves to provide a means of addressing the insights and aids in responding to customer as and when they engage. The ability to produce effective functionally that is of value goes beyond automation and integration -it requires meaningful understanding and almost instant response to follow the flow of behaviour and usage. It requires functional response that assists humans using these applications.
I have been involved with custom application development in the Microsoft environment for over 20 years. I helped start a company called Shandon in 2000 in the middle of the IT dry spell which followed Y2K. The motivation for starting the business was to take advantage of the immerging opportunities that the Internet was providing businesses, by meaningfully interacting and transacting with customers. We learnt a lot very quickly and had our fair share of solutions end up on the ash heap. Learning from our mistakes was as important as the projects that succeeded. We have been very fortunate to have worked on projects in a number of industries from property management, banking, credit bureaus to name a few. The pinnacle of our efforts has been the opportunity to be part of an online solution that has affected how people submit and pay their taxes in South Africa.

Experience the excitement of the physical web with me and BB-8, the Star Wars app enabled droid. This little robot comes with an Android and iOS app so that you can control it with your phone. However, we should not just settle for an app provided by others when we have the knowledge and tools to create our own. The idea of the physical web has created a disturbance in the force. With just a simple web page, we can now connect to “smart” devices using technologies such as Bluetooth and WiFi. The ability to do this, will soon be a standard in all new operating systems and browsers. This means that we will no longer be limited by our phone or tablet or the version of an operating system we are running. Join me and BB-8 as we explore all the opportunities that the physical web can provide for this little droid. We will build a website, deploy it and control our little droid. With only a smart device connected to the internet you, the audience, will be able to find the droid you are looking for.

She loves Star Wars, and because of that spends a lot of time hacking her BB-8 droid as well as exploring other IoT concepts and ideas.
Justin Worthe
Hi, I’m Justin, and I play the trumpet. I’m a software engineer, bad musician, and chronic yak shaver, so when I discovered that my intonation was bad while playing the trumpet the obvious solution was to start programming. The idea was to have an application listen to me playing and give feedback on my pitch. This application is written in my current favourite programming language, Rust, and so my Rusty Microphone project was started.
Now that I have something that works, I’m looking at ways to make my application available to the world, especially to musicians. Musicians are not widely known for their ability to clone a git repository, assemble the necessary collection of libraries and compilers on their computer, and compile things, so I went looking for distribution methods.
As someone who spends his working hours building web applications, I’ve seen many cases of web applications that have been packaged as if they’re a smartphone or desktop application. What if I tried the reverse, and packaged my desktop application for the web? With Rust’s support for WebAssembly, this should be easy, right?
This is the story of me taking my Rust application and figuring out how to embed it in my website.
Justin is a software engineer, working on both sides of the Internet in the web development stack. This has resulted in a considerable amount of JavaScript. In his spare time, he likes to tinker with lower level languages and concepts, which has lead to his current fascination with Rust.
Wherever possible, Justin prefers to use free and open source software. He also tries to give back to these amazing online ecosystems by writing about what he's up on his blog, including code examples with open source licences for others to use and learn from.
His pug is not currently plotting world domination. Everything is fine.

Marco Heimeshoff We build software that changes the world. From optimizing small companies to connecting humans and businesses on a global scale, our work plays a hidden but major role. Software development is not about software, it is about understanding the customers domain and solving their problems. We need a culture, a way of thinking about the needs of the customers first and putting an emphasis on their language and human interactions. If we let the domain drive our design, we can tackle complexity in the heart of software. The pillars of Domain Driven Design are learning, language and empathy. With the right mindset it becomes simple to derive good models, keep them pure and aligned with the business. Simple is not easy, but done right Domain Driven Design transforms everything in your organisation: code, culture, agile and architecture.10h00 → Movement, Networking, & Snacks ← 10h30

It is not always a cookie cutter in the making, and often times there are a lot of tears, but when they all buy into the dream, that's when magic happens...
Janco WolmaransThe tech landscape is changing faster than ever, and this trend is only accelerating. How do technical people grow when the world is changing faster than you can finish your next cup of coffee? How does one keep up? What should you learn? Are there things we can focus our learning efforts on besides just the next tech flavour of the month? This talk will explore some areas of learning that technical people might not intentionally consider. These areas focus on higher-level concerns, with slower rates of change, which can help technical people develop into more well-rounded individuals.

Donovan Graham
The micro-services models has changed how we think about developing application services. By defining smaller clear service boundaries it makes it easier to build, test, deploy and isolate failures. Using a similar approach, this session shares how you can carry the same benefits into frontend development. Within a large application, breaking up a frontend monolith into micro frontends allows teams to form around solving and owning a particular feature. Teams are cross-functional across backend and frontend and able to operate independently of each other. They can use different languages and typically own the continuous delivery and ongoing maintenance of the feature in production. Micro frontend work side-by-side or together inside the same html page wrapper leading to a cohesive end-user experience.
Donovan is a senior engineer at Allan Gray. With over 16 years’ experience in building and leading start-up teams, the last 2 have been helping digital and tech transformation in financial services.

Robert BraveryBots, AI and Cognitive learning is going to change the way we life, how we think and how we work. It will also change how we code and how we analyse data. Automated and driverless vehicles are one example of software bots and mechanical robotics interacting. Deep learning and Natural Language Processing (NLP) will make it possible to ask virtual bot assistants questions in a natural way and get meaningful answers. Analyzing huge amounts of text, social media posts to understand sentiment and thought process will be a huge advantage to business and even government. Face-recognition and photo-analysis at the hands of the populous makes searching and analyzing digital data easier smarter and more accurate. Lear how we can make use of Bot Frameworks, AI Frameworks and Cognitive Frameworks that are available today to achieve what we might have thought previously impossible or event at the least out of our reach.

Once upon a time Martians and Venusians met, started working in agile software development teams together, and had happy relationships because they respected and accepted their differences. Then they came to Earth and amnesia set in. (They forgot that they were from different planets.) Based on years of successful counselling of software developers and testers, Software Developers Are from Mars; Testers are from Venus has helped one team (somewhere) transform their relationships. Now viewed as a tongue-in-cheek talk on modern software development, this phenomenal discussion has helped software developers and testers realise how different they are and how to communicate their needs in such a way that conflict doesn't occur and relationships are given a chance to grow.
I'm the head of SQA Architecture and R&D at DVT and love seeing screens flickering away with automation scripts. Weekends are spent on my extreme makeover DIY house project. I am a dreamer with my head in the clouds most of the time, and I absolutely love software testing!
Amy CodesKubernetes has become the de-facto standard for container orchestration today. However beginner-level educational content to learn Kubernetes today is still focused on cluster management through the Kubernetes CLI tool. This can make it harder for novices to visualize the relationship between the commands they’re issuing and what’s happening in the cluster. Incrementally building a Helm Chart provides an easier, more intuitive, and more visual way of learning the key concepts of Kubernetes, while addressing how to manage package releases upfront.
This talk will cover how to incrementally build a Helm Chart for NGINX, and along the way, will cover key Kubernetes concepts. Content will include as many diagrams and visuals as possible to accompany these concepts, and include how to deploy the new NGINX chart from a Kubernetes cluster.

Rebecca FranksDeveloping Android Apps has notoriously been a difficult task. Previously, Google refrained from giving advice as to how you should go about architecting your Android applications and it has been “left it up to the reader” to decide how. This lead to apps having a lot of bloat in their activities and being really difficult to test. This has now changed since Google I/O 2017 where the new Android Architecture components were introduced. The libraries aim to make developing and maintaining your Android apps a lot easier. In this presentation, Rebecca will present the components and dive into detail around the different types of tests you should write (and where) for your newly architected Android application.
Rebecca Franks the Android Engineering Lead at DVT. She has over 5 years experience in developing Android applications.

Processing your log files could reveal a host of useful information.
Join me for a hands-on presentation, where we’ll pull some useful open source Docker containers and set to work making them weave some magic on our log files.
We’ll cover some Docker Compose basics to get you started with a simple ELK stack (Elastic Search, Log Stash and Kibana), configure some endpoints and setup log shipping (for Linux and Windows) so that we can process log files.
Once we’re processing logs, we’ll look at ways to transform and embellish our log data to add IT operational, as well as business value.
Using our transformed data, we’ll also cover visualising the data using Kibana.
To close out we’ll also consider alternative technologies such as Prometheus and Grafana, and discuss the pros and cons of the different technologies.
Mining log files has never been so simple.
Join me to see how easy it is to get started.

Marco SlavieroFor years and years, network pen-testers have owned companies and networks with playbooks written in the 90’s. With a good mix of footprinting, scripting and unexpected interdependence, even moderately skilled attackers have been able to reign supreme without ever needing a 0day. How does this change as organizations slip more and more into the cloud? What do rootkits look like and what does lateral movement mean when its between different SaaS products? In 2009 we took an initial stab at answering some of these questions, and now we’re revisiting the topic in light of the huge strides made in cloud services.
We cover a few recent attacks on companies that leveraged cloud services, showing security failures can occur on the boundaries of, rather than solely in, services. We demonstrate easy and novel ways to embed compromise detection capabilities in third party services without requiring support in those services. We show how developers can be attacked with malicious code editor plugins. We tackle the gorilla, Amazon Web Services, revealing a series of attacks that cover reconnaissance, compromise, lateral movement, privilege escalation, persistence and logging disruption. Lastly, we end off describing how to aid compromise detection in cloud services.
Marco Slaviero is the lead researcher and chief dev wrangler at Thinkst. Marco has presented research at security conferences on a range of topics including timing attacks, Python shellcode, sock puppets, honeypots and cloud security. He is rumoured to harbor a personal dislike for figs.
Tim LewisThe JAMStack is a new way to approach creating a website or web application. In the past if you wanted to get something online, you’d have to spin up a server that was always online. If you wanted to keep costs down that server would have to be small, but that meant you couldn’t handle large traffic. If you wanted to scale cost-effectively, that meant you’d have to use someone else’s platform, which meant you lost some control. JAMStack allows you to create full websites that are fully delivered via CDN, but without losing functionality.
I’ve used JAMStack to create a personal blog, a corporate publishing platform, landing pages and product MVPs. The JAMStack is a very flexible tool that allows you to get your content in front of people, easily. Youre site consists made up entirely of static resources, that can be delivered through a CDN. If you need more processing, you can then offload those to ‘hosted functions’ like AWS Lambda, Azure Functions or the like.
In this talk I’ll walk through the details of the JAMStack, creation of a site, how to deploy one and building in features like search and more complex functionality.
Tim Lewis is a full stack developer and a Team Lead at Entelect. Professionally, he's worked in risk management and fraud prevention, the health sector, lectured web design and been a web freelancer. In his free time, he is a UI/UX enthusiast and keeps a keen eye on cyber security. When offline, he is involved in a couple of charities related child protection and education.
Mike GeyserThe holy grail of web applications is having them be near-native performance, and to a large degree this has driven the JavaScript revolution. To truly realise that goal we need to embrace native design thinking for our applications, applying it not only to our code but also to our content. Using ideas from Progressive Web Applications and a modern framework such as Angular we can create engaging, fast and available application experiences - the best of both native and web.
This code-oriented talk will show how to practically use select principles of Progressive Web Applications in conjunction with Angular to create fast and compelling web experiences. It will cover the creation of an application shell and go into using service workers for preloading, caching and even offline support.
Mike Geyser is a programmer at BBD in the R&D team, co-organiser of the Jozi.JS meetup group, a frequent technical speaker, and loves the web. He has been hacking on it since Geocities was a thing, and has the keening wail of dialup modem etched into his subconscious. While he is fluent in several ‘golden hammer’ programming languages, he has a long-lived love affair with JavaScript, and cannot see its (many, obvious) flaws. He has worked on lots of interesting enterprise applications, but it is the challenges of the public web that really appeal to him - having spent his formative years building transactional websites. He is always eager to talk about the web platform, but be warned, he is prone to hyperbole.

Since the dawn of man (And indeed, Kerbalkind), we have looked up at the moon and stars and wondered ... is there cheese out there? Seeing as how modern science has yet to answer this question sufficiently we set out to see for ourselves.
In spaceflight people use physical switches, dials, buttons and readouts to pilot their vessels. In the game Kerbal Space Program you use a mouse and keyboard. In order to get a more authentic experience, we set out to build a KSP Control Board.
As you can see from some of the sample pictures, a few people have managed this before. However most of it is written using C# since that is what the game is written in. Because JavaScript is awesome, we set out to use that instead.
There is a mod for the game called KRPC which allows you to use Google Protocol buffers and WebSockets to communicate with the game remotely. We wrote a node.js module that can be included in any regular app. Using this module, and Johnny-Five we wrote a node.js script that can interface with the Arduino. The Arduino in turn interacts with the various physical switches, buttons, joysticks, sensors and a LCD.
In addition we wrote an auto-pilot script that is capable of doing SpaceX Falcon 9 style return to launch site mission using a script written purely in JavaScript.
Ryan Kotzen is a recovering enterprise developer. Ryan joined Entelect in 2009 fresh out of varsity (UJ) and has been there ever since. He has worked in a wide range of domains including fintech, health, employee and customer loyalty, gamification, event management, and retail. Ryan started his career in .Net and was part of the founding of the start-up Encentivize where he gained a wealth of knowledge about JavaScript and the MEAN stack. As an Engineering coach within Liberty dHub, Ryan has had an opportunity to deliver a mobile app written in React-Native and exercise his automation and DevOps skills, dabbling in Python, Ruby and GO. He has a passion for teaching and coaching others. When not developing software, Ryan likes to spend his time playing Kerbal Space Program and engaging in the Warhammer 40k hobby.
After spending some years dabbling and failing in the arts, Jake moved onto studying Electrical Engineering at the University of the Witwatersrand. Despite the big change in direction, he did well enough to graduate in 2014. By this point he knew he wanted to work with software, and was promptly hired by Entelect where he's been ever since. After spending some time as a .NET developer, Jake started to become interested in JavaScript as more and more of his work required it. Then one day, Ryan (Jake's co-presenter) sent him an image of someone's homemade Kerbal Space Program control board, and said "Hey, we should try something like this, but with JavaScript!". Thus began the work that lead to them presenting this contraption at the JSinSA conference, and now, at DevConf. When not coding, Jake can generally be found looking up at the stars, or playing some space themed computer game.
Willy-Peter SchaubHow do you migrate over 65,000 of the most demanding software engineers from infrastructure built up over decades of high-intensity work into a common engineering system based on modern software development technologies and best practices? This is exactly the challenge faced by Microsoft as they moved to their One Engineering system. Come and hear about how they did it and the lessons they learned along the way.
Willy is a program manager with the Visual Studio Team Services (VSTS) group. He’s responsible for the ALM | DevOps Ranger community, which provides professional guidance and gap-filling solutions to the developer community. Go directly to him if you need help with missing guidance or features for VSTS. Since the mid-’80s, He’s been striving for simplicity and maintainability in software engineering. Reach him on Twitter at @wpschaub, or the aka.ms/vsarblog, aka.ms/willysblog blogs.
William BranderAs developers we spend a lot of time structuring our systems just right. We make sure we select the right patterns, use the right combination of acronyms (CQRS + DDD + ES), and do all the right devops so that we can scale up/out/elastically. This adherence to best practices seems to fall apart at the front end though. We have separation on the back end, but on the front end this all needs to come together. How do we stop it from turning into a mess of spaghetti code? How do we prevent simple actions from triggering hundreds of web requests? Join William as he builds a .NET Core Composite UI from scratch.
A professional geek, William works for Particular Software writing amazing software like NServiceBus. Passionate about the web and security, he is engaged in a sordid love affair with JavaScript, and spends most of his free time trying to convince others of it’s beauty and elegance.
When not behind his laptop hacking away, this amateur beer enthusiast can often be found playing boardgames or drinking cold-brew coffee.
