Building an API easy enough for kids to understand (in C++) is a challenge. Every design decision, from the circuit board to the plastic can effect the results. We’ll talk about product design, manufacturing, firmware, software, and Arduino AP as we cover the Jewelbots timeline from Kickstarter to shipping to distribution.

IOT and Event Based systems can process huge volumes of data. Which typically needs to be stored and read in near real time for event processing, in addition to being read in bulk to feed data hungry learning systems. Apache Cassandra provides a high performance, scalable, and fault tolerant database platform with excellent support for time series data models typically seen in IOT systems. It's millisecond (or better) latency can support systems that react to events in real time, while scalable bulk reads via batch processing systems such as Apache Hadoop and Apache Spark can support learning applications. These features, and more, make Cassandra an ideal persistence platform for modern data intensive, event driven, systems.

In this talk Aaron Morton, CEO at The Last Pickle, will discuss lessons learned using Cassandra for IOT systems. He will explain how Cassandra fits into the modern technology landscape and dive into data modelling for common IOT use cases, capacity planning for huge data loads, tuning for high performance, and integration with other data driven systems. Whether starting a new project, or deep into the weeds on an existing system, attendees will leave will leave with an understanding of how Apache Cassandra can help build robust infrastructure for IOT systems.

At this very moment, there are over 5 billion people tapping and swiping on their mobile phones in every corner of our planet. There are people in Sri Lanka tapping and swiping, South-Africa, Ecuador and Tanzania. The Albanias and Swedes, also busy tapping and swiping.

As a technologist, your aim in life is to capture as many of these tappers and swipers as you can. Given that there are only about 22 million developers in the world, it is likely that the tappers and swipers will not at all be just like you. Building a product for people like you, therefore, greatly limits the size of your total addressable market - which in short, is really bad business.

We know that startups co-founded by designers are far more likely to succeed. But why is this? What exactly do these mysterious Design Creatures do, and more importantly, what can you learn from them to help your product win the tapping and swiping game?

Join Anna for an entertaining, practical and example packed presentation that will absolutely change the way you view the role of design in the making of your next product.

Creating inclusive and accessible apps is easy using React Native! Javascript developers can have a working app on their phone in less than an hour. Join me to see a working demo of how to plan, develop, and test for accessibility in the mobile space.

I will also be talking about resources and guidelines you can use and share with your organisation to develop apps for everyone - including what the bare minimum looks like to help you prioritise your requirements!

There are many advantages to using vector-based assets in your Android apps — smaller binary size, faster loading, easier support for all pixel densities, dynamic drawing, and more ways to animate. Despite the upsides, SVGs and VectorDrawable assets are more complex to author and use.

Luke and Marc explore everything needed to create, export, and implement SVGs and VectorDrawables on Android, including common issues and their remedies.

The Internet of Things is undeniably here. In the last year we have heard tell of of security cameras, dishwashers and even ovens roaming the internet unsupervised.

As a consultant and writer about the Internet of Things, I have worked to bring my experience from 20 years in manufacturing and internet security to the IoT world. This presentation will cover the tools and techniques I use to build secure, reliable and rapidly updatable IoT devices.

The techniques covered are applicable to both the simplest embedded devices with no general-purpose OS, and more powerful devices running Linux or Windows.

Implementing IoT projects doesn't have to be difficult, time consuming and expensive.

MicroPython brings Python 3 to embedded platforms, and since Python is one of the easiest languages to learn, and there are WiFi SoCs available around $5, this is a great way to get started in IoT! We'll look at:

• What is a System-on-a-Chip (SoC) with some specific examples based on the ESP8266 and ESP32 WiFi SoCs
• Why Python? A quick look at C and IoT vulnerabilities
• How to install MicroPython and communicate with the ESP SoC to write programs
• What it is capable of and what things are being developed for it
• How to contribute to the MicroPython project

I started off my life as a developer writing machine code and C and working on some low level hardware projects. Then this thing called the internet come along and I moved into the web application space for a couple of decades. More recently I've moved back into commercial IoT development and not unexpectedly a lot has changed over that time.

In this talk I'll cover what it's like developing IoT projects. I'll go over the tools you need and protocols you need to be familiar with. I'll look at how the C language has evolved to what it is today and and how to write code that works well on memory constrained devices. I'll go over producing prototypes, rapid development, debugging and testing embedded applications and what and how much electronics you should learn.

In short everything you need to know in becoming an IoT developer and have fun doing it.

The ThinkerShield for Arduino makes it easy for anyone to get started with programming and controlling things with their computer in minutes! No need for any wiring or soldering or program knowledge. Even if you have never seen a computer program before, with the ThinkerShield you will be making things flash, buzz, beep and respond in no time! It has been designed over a 4 year period with multiple prototypes and is now going to be used in the NSW premier's code challenge and 1000's of units are in schools across every Australian state.

This talk will share the challenges of getting this to product form and why people should care about ThinkerShield.

"Immersive" is the key defining factor of the next wave of computing. With each computing revolution the distance between the user and the computing experience has shrunk - with today's modern mobile devices making computing Pervasive. This next step is truly user-centered and puts you right at the heart of a deeply Immersive Experience. The key question that faces us now is "How do we get there from here?". Our near future seems to inevitably involve hyper-connected wearable and then embed-able computer displays. But how will we all migrate from today's mobile devices to this amazing new nerdvana?

This session takes a detailed look at what makes "Immersive-ness" so important. What standards and market forces are driving this evolution. And how you can navigate your way through all the technological change this will bring.

A lot of us work in an environment where we support an iPhone app, a mobile website, and a desktop site. But why do we only support Google searching for our web facing platforms? Shouldn’t we really allow Google to search and link us straight into the relevant area of our iPhone apps too?

Well in this presentation that is exactly what we are going to learn how to do. We’ll first explore why it’s so important to build an app that supports app indexing. We’ll look at some apps that do it well and see the enhanced user experience this produces, and discuss what would be potentially lost if Universal Links hadn’t been used to provide this user experience.

We’ll then dive head first into the technical side of what’s powering the experience, and what needs to be setup before Universal Linking will work for you and your iPhone apps. This will include tips, tricks and traps drawn from real-world experience.

Petrol stations are dangerous places. Constant monitoring and analysis is crucial to ensure operation is safe and efficient on a daily basis. But the devices that monitor the stations are old and dumb where information needs to be pulled to be analysed.

Well, we inverted that - and found interesting challenges to solve.

From design and development of new hardware to the implementation of a new system providing real-time information about their petrol stations, I will tell you what it's like to be involved in a project with so many variables.

This talk is an Experience Report sharing the highs, and the lows, from the first few months of building Xinja - Australia's first digital bank, designed entirely for mobile. A talk from two perspectives; both Business (Van Le - Customer Innovation Director, Xinja) and Technology (Phil Parker - Partner, Equal Experts) will share the journey we are going on… warts and all!

We will share how we manage priorities when developing with our customers (shout out to our founding Xinjas!), how developing a startup does not mean being technology lightweights (or cowboys) and how we manage to be effective with a highly distributed, global team.

At WWDC this year, Apple announced their CoreML and Vision frameworks. These allow you do easily implement machine learning models inside your app, running on the GPU on an iPhone. Suddenly a world of machine learning is possible in ways that it wasn't before.

In this talk, you'll see a real world example written in just hours which implements a freely available object classification model to find out who is a good dog. Silly as this sounds, it shows the power now at our disposal.

We’ll look at what you need to do to build a simple app, and then dig into some of the innards of machine learning to see what we need to do to create something really useful.

As the future approaches us more and more rapidly, we feel the impact of the choices we make today sooner and with more force. This talk offers practical advice on how to drive and deliver value to a business continuously by building systems that scale to the needs of a business working towards an unknown future.

Did you know that less than 30% of the internet population speaks English? And this percentage is slowly decreasing as cheaper smartphones become ubiquitous and new users from Brazil, Russia, India and China come online everyday. If you want to reach this global market, it is important to translate your mobile apps into your user's native language. This is why Canva decided to build a localised app from the get go.

In this talk, we will present a quick introduction to internationalisation and the key things to consider when localising your mobile app. You will learn about the various tools available to enable translations at scale and how those integrate with your app. You will also get some hands-on, practical information about the unique development challenges presented by languages that have different pluralisation rules to English and languages that are written from right-to-left. We will show some examples of our internationalisation approach in our iOS app. Lastly, we will wrap up with how this fits into our Feature development and Release process. Expect lots of practical advice that will help you get started on localising your own mobile app.

Diving into the feasibility of using a single code base for generating multiple front-end applications.

We'll discuss using React and React-Native for building apps that provide a consistent experience across native, mobile and desktop web.

Using React and React-Native as the UI layer upon a shared JavaScript core codebase can greatly improve your organisation's delivery of new features to customers.

We'll talk about our migration strategy for the new apps replacing our existing apps, piece by piece. Not slowing down our continuous release of features to customers while replace the apps.
