You may have heard the acronym SOLID. It is one of the most widely-referenced sets of software design principles, appearing everywhere from architecture guidelines to job descriptions. It's also closely associated with the Object-Oriented Programming (OOP) paradigm.

This talk builds a critique of OOP through an exploration of the SOLID design principles. You may be thinking something along the lines of "overengineering" or "unnecessary complexity". But this talk makes a different point: that the simple, maintainable software engendered by SOLID principles may be best achieved by thinking outside of OOP.

HTML, the foundation of the web! With so much time being spent on typed javascript, functional programming, unit tests, visual regression testing, tools, frameworks and a drive to write better more efficient code we often forget that the web starts with HTML.

Let’s talk HTML and semantics and why choosing the right HTML elements will help you write more accessible, efficient and maintainable code not just in your HTML but your CSS and Javascript as well. 

Most importantly we’ll explore why HTML is so vital in improving your projects overall functionality for people and for bots.

As a software professional it can be an amazing experience to see your company grow rapidly - winning new markets, shipping new features to customers, and welcoming a swathe of new colleagues along for the journey. At some point though, the rocket you're riding in breaks free of the atmosphere and settles in for the long haul on its journey to sustainability - and it's at this moment that you might begin to notice some problems.

Why is it that when you search for "release process" in the wiki that you now find five pages instead of one? When did setting up a new dev environment for the new starter become a two week long headache? Why does your phone keep pinging with alerts from three different monitoring systems? And how do I pronounce Kubernetes, let alone use it?

In this talk, we'll explore how one individual saw this myriad of scale up side-effects as an opportunity to create a new function within their company dedicated to improving the day to day experience of engineers. We'll cover what it took to bootstrap this function, the challenges that must be overcome, and why your workplace could benefit from a more direct focus on the engineering experience.

Ever watched Air Crash Investigation? You may not be an aviation nerd, but there are so many fascinating parallels between security and the aviation industry: the layering of safety controls, making sure there are different types of security controls in place, the improvements made after bad things happened, etc. 

In this talk I'll discuss some of some notable examples in both the aviation and security industry and what we can learn and take away from that as security professionals.
Note: You don't have to be an aviation geek to enjoy this talk, promise!

Observability ( o11y )  is a practice that helps provide better insights into application behaviour,  to enable the earlier identification and rectification of application defects.  
Most developers come across o11y  when assigned a bug report from IT OPS with a log file attached, this log file usually contains any information that has been pumped to stdout() !!  .... usually not that helpful. 

  There is a lot more to o11y than this.  Using concrete examples this session we will go through what developers should know to improve their applications observability when running on AWS.  We will highlight some best practices, tools and services that you can leverage to help with observability on various application stacks.

The best problem solvers are the best problem finders. But they don’t just find any problem, they find the right problem that needs solving.
Problem solving is a fundamental skill that we are taught throughout our school years. However, I believe we are only taught half the process. We are taught how to look for solutions and solve for the problem in front of us. 
However, what about how to find the problem? Or how to find a better problem? 
You might be thinking, I have enough problems already why would I want to find more? But I propose – we will always be presented with problems in every aspect of our lives, we need to be selective with the ones that we are solving, and by teaching ourselves how to identify problems, we can give ourselves the option to select which ones we want to solve.
Let’s consider what we might need to know about finding some new better problems, and how to move past potential obstacles to problem finding. 
In this talk I cover the 4 key pillars of successful problem finding (curiosity, creativity, embracing uncertainty and collaboration) and how to overcome potential obstacles.

Single page apps (SPA's) have become a very popular way to build web applications. They offer incredible developer experience and allow the web to become far more ‘app like’ than ever before.

There is one problem with SPAs though; they actually suck.

In this talk I will take you on a practical deep dive show you how we can do better than the SPA  model. We'll revisit our roots in traditional web apps and learn how we can use the same motivations that made SPA's so popular and re-apply them in a way that will make the web a better place.

SPAs: where did it all go wrong

The aspiration for a comprehensive suite of automated tests is universal, yet the desire to maintain these often fragile and hurriedly constructed tests is scarce. Ignored test failures accumulate, while the necessary time and effort to rectify them seem to be perpetually out of reach.

What if we could change that? What if we could harness software engineering's best practices to make our automated tests not only more robust but also more efficient and easier to maintain?

This talk explores the transformative impact of applying SOLID principles and the DRY (Don't Repeat Yourself) principle to your testing code. These strategies lead to tests that are quicker to write, offer improved coverage, and - most importantly - are easier to amend when the underlying codebase or its dependencies change.

Drawing from my craftsmanship, I will illustrate how these principles have revolutionised my testing approach for both front-end and back-end code. I'll share my journey of creating a test suite that can be adapted rapidly to changing dependencies and provides such extensive coverage that errors can be pinpointed to their exact point of failure.  

Join this talk to discover how to leverage your software engineering prowess to craft robust, comprehensive tests that remain effortless to maintain.

As digital transformation is sweeping across every aspect of life and business processes are becoming more complex, the software testing function in IT projects has become more crucial than ever. The ever evolving technological solutions and constantly developing business needs are taking software quality assurance to the next level where some burning questions are yet to be answered:

Why is software testing still vital to the success of any IT project?
Why is it so challenging to perform testing effectively?
How will AI shape quality assurance?
How to find the best approach tailored to the individual needs of a company?

In the quest of finding answers to these questions, most IT professionals quickly encounter the prospect of Testing as a Service (TaaS) as a viable solution. A true TaaS model not only guarantees scalability of resources but also successfully bridges any knowledge gaps in a project.

A carefully selected automation strategy combined with the most recent, highly innovative automation testing tools grants a seamless and accelerated testing process. This allows human resources to be utilized for more focused and complex work, so that 'humans can do that computers can’t'.

The rapid emergence of sophisticated AI solutions are taking software testing to new dimensions. Leveraging AI in testing enables the combination of existing testing tools, artifacts and processes which will result in better software quality, therefore a better quality of life for all.

The New Dimensions of Software Testing

We all love problem solving, but leave me in a room without one and I'll eat the couch.

This talk will provide you with some practical tips for designing better software. It will cover a range of areas including product discovery, architecture, design and a code example.

Recently I've worked with a number of software teams in Perth and spoken with many companies about how they're building software. We've come a long way since waterfall and we now have some new problems. This is a good thing, we've made progress! But we still have a long way to go. These tips will help alleviate some of these common problems.

I hope there will be a little bit in here for everyone.

The Problem with Problem Solving

Metrics… 
We all talk about it, we all want to use it but do we really understand the impacts of the act of observation? 

The Observer Effect was first studied by Schrodinger in the classic "Schrodinger's Cat" experiment. If you're unfamiliar with Schrodinger's Cat, it's as follows. 

In this classic thought experiment, a live cat is placed in a box with a poison that can be released at an unpredictable time. Later in the random future, you (the Observer) decide to open the box. You find the cat is dead; but the question is, was the cat dead the instance before you opened the box? Physics says it's impossible to say because of the unpredictable poison and the random time to open the box; therefore your decision to open the box had a quantifiable impact on the cat's death.

Is there a correlation between the Schodinger's paradox and metrics? …. I believe there is. 

In this talk I'll share some of my experiences working with delivery teams and seeing how they modify their behaviour in response to their awareness of being observed. I'll also share which agile metrics are best to use, based on the outcome you're looking for. 

**disclaimer: I am an animal lover and no actual cats were ever used during this experiment :)

The Schrodinger's paradox and metrics … does our curiosity kill the cat?

It's easy to tell stories about people whose experience in the tech industry is unusual. Some of those stories are focused on innovators, but many are about 'trailblazers' from marginalised and under-represented groups. These articles often focus on the strength, perseverance, and resilience that it took to get there. However, that's only one part of the story. The ways in which under-represented people enter, experience, and hopefully thrive in our industry are far more complex.

Very few people advance their careers on positive attributes alone. The experience of people from marginalised groups depends on the managers, companies, and communities who put in the time and effort to identify, employ, and sponsor them through their careers. Technical communities have a role to play in this process; they're a frequent first point of contact for young folks and potential career-changers, and a place where people are free to learn and make mistakes with the support of mentors and long-time community members.

In this talk, we'll analyse what it means to be successful when nobody in the room looks like you, and break down the narrative of the trailblazers in the tech industry. Then, we'll look at the role that tech communities play in increasing diversity and fostering a sense of belonging in the industry. By the end of the session, you will have learned how to shape communities where difference is both ordinary and celebrated, and translate these skills into a commercial workplace.

The Stories We Don't Tell

Ever wonder how some technical people are recognized and promoted quicker than others with the same skillset? Yes, there is a formula to make it more likely. We will explore the habits of well known developers outside of their coding chops, to identify what additionally allowed them to become a trusted and known voice in their environment. This approach can be a benefit to you, no matter how junior or senior you are.

Heather Downing

The Visible Developer: Why You Shouldn't Blend In

ICT delivery is often presented as a binary choice between extremes:
●	Everything Waterfall – all solution requirements are defined up-front or early in the project lifecycle, and the project follows a pre-defined, largely predictable process with outputs delivered in order. 
●	Agile or Nothing – the project uses a framework of agile ceremonies and rituals to continuously discover, review and reprioritise solution requirements, developing and refining outputs incrementally.

This binary view of is increasingly being challenged. Many initiatives involve the delivery of both digital products normally associated with agile approaches, and physical deliverables traditionally managed using waterfall methods. In addition, many initiatives are required to follow prescriptive processes, such as governance and approval processes - regardless of the delivery approach used.

This presentation considers when and how agile and waterfall approaches can be used in combination to deliver work. It discusses factors that can determine whether and when different approaches are combined on an initiative, as well as considerations for ensuring the delivery of holistic solutions that satisfies business needs.

To Agile or Not to Agile: An Iterative Dilemma

In this talk, I want to dive into the realm of data quality assurance through Continuous Integration and Continuous Delivery (CI/CD) practices. We explore how a CI/CD pipeline acts as a safety net, catching data inconsistencies and errors before they impact the end-users. From automated testing to timely data validation, I will discuss how these principles increase data reliability and trustworthiness. Revealing how I have leveraged CI/CD to create a robust data quality assurance framework.

Turning Dreaming into Doing - A Life Manual for Nerds

We love code. We love new languages and language features, elegant architectures and ingenious algorithms. We love it so much that sometimes we get blinded by the pizazz and forget about the all the other parts of writing software beyond the code; the countless hidden dangers that can sink your software project.

In this session, we'll look up from the keyboard and broaden our horizons. We'll look at common bottlenecks, tools we take for granted, processes we don't think about, and relationships that go unspoken. We’ll focus on the bigger picture and see how going outside the confines of code can make us more valuable to the companies we work for and the teams we work with. Code is great, but it’s only a detail in a much larger organism.
