What is code - Part 1
This document provides an introduction to what code is and how it is compiled. It explains that code is written in programming languages that serve as translators between human language and computer-understandable binary. When code is written, it must be compiled by tools like GCC which translate it into binary executable files that computers can understand by referencing syntax definitions provided to the compiler. The compilation process involves translating, linking, and generating an executable containing translated code.

Continuous testing at scale
0/5
You’ve built a new feature in your app that is ready ship. Or is it? How can you be sure you’ve not introduced regressions in cases you forgot to test? What if your code crashes only on certain devices? Could the feature freeze up for a few users?
Shipping frequently with little to no functional, UX or performance issues or regressions is not easy - but it’s also a problem that has been solved before. Where things get a lot more interesting is how to keep the same quality bar when you have hundreds of pull requests going in every day, with tens or hundreds of developers working on the same project? How do you test that your app still works - with this kind of scale?
In this talk, you’ll learn about the different approaches we combined into a system used by hundreds of mobile engineers at Uber to test our native iOS and Android apps during development, at release as well as when in production. We’ll talk about what did and what did not work for us on our journey of iterating frequently and continuously improving the quality bar.

"Production Driven Development", Serhii Kalinets
Teams often waste effort on such useless things as integration tests and maintaining multiple nonproduction environments. Moving to an only-production viewpoint would save countless engineering cycles and put effort where it matters.
In this session we will discuss why eliminating nonproduction environments is not such a crazy idea. We will review tools and practices that would help teams to deliver their services with confidence and much faster than with standard approaches.

Synchronized Development for Distributed Teams
Distributed teams face challenges like staying informed, handling personality issues, avoiding overlapping work, getting feedback, and dispersing knowledge. The presenters recommend techniques like branching per feature, test-driven development, design by contract, using a Kanban board, dependency injection, daily stand-ups, pairing, and event aggregation to help address these challenges. They also discuss tools like version control systems and time trackers to support these techniques for effective synchronized development across distributed teams.
Versioned Page Objects: How to handle 12 versions of web application
In automatic tests, it is often difficult to work with pages that differ depending on the screen size, type of user, localization, or other conditions. And when you work with such pages - a strong desire arises - “the page is almost the same, i just need one additional click for mobile version ...”, and often “if / else” becomes the solution. In this talk, I want to show the approach that I use in the current project, which allows me to support and develop tests for 12 versions of the same web application. I called this Versioned Page Objects. It allows to reuse common logic between different versions of page through inheritance, and also override or remove some logic where necessary, without any if / else blocks across the code. TypeScript code examples
Behaviour Driven Development (BDD) - Closing the Loop on a Great Fiori UX
BDD (Behavior Driven Development) involves defining requirements as structured scenarios to guide development and act as automated tests. It promotes collaboration between developers, testers, and customers. User stories and acceptance criteria written in a common language like Gherkin provide requirements, documentation, and tests. Automating tests based on these scenarios provides fast, reliable feedback to close the development loop.

Design System as a Product
Design System as a Product - Maria Elena Duenias, Esther Butcher
Design systems are a great example where web development and design meet. You can find innumerable resources on the internet, books and conferences on how to build them, and how they are exactly what your organization needs. But, building one requires a lot more than following a recipe. In this talk we are going to discuss how to build a design system as an internal product, and how it evolves to become what the users need.
Designers, Developers & Dogs
Designers, Developers and Dogs: Finding the magic balance between product and tech - Charlotte Vorbeck, ShareNow and Sahil Bajaj
How can an agile delivery team become a successful product team? When does collaboration between product and tech succeed and when not? Why do people in some teams inspire each other while others in the same environment don't speak the same language? In this talk we want to share our learnings and experiences from rebuilding an internal tool for customer support at ShareNow. What could have been just another boring rewrite surprisingly became one of our best experiences in collaboration. We will look at how a joint discovery phase helped us to come up with a shared vision, how a better team setup enabled us to do the necessary work, how focusing on the customer kept us aligned during our journey, and also how we built upon existing collaborative techniques to achieve this new level of cooperation and trust.

More impact with flexible teams
How to create more business impact with flexible teams - Jan Hegewald, Zalando & Rebekka Beels, Zalando
Usually, Software Engineering teams are organized around a fixed set of components which they develop further and maintain. Such component teams gain a high level of expert knowledge about their services. However, with agile product development, it often is difficult to implement the most important initiatives with such teams. This leads to a situation where the teams do not work on the most relevant business topics but on those for the respective team. At Zalando, we introduced a new model where we shape teams flexibly around business goals to create the highest impact. How we organize these teams and which challenges especially for the software quality need to be addressed, will be explored in this talk.

Dual-Track Agile
Dual-Track Agile for Discovery & Development - Adriana Katrandzhieva
The talk will focus on one of the ways teams can ensure continuous delivery and design in their projects. The so-called ‘Dual-track’ model shows the parallel tracks of discovery and development throughout the product design and delivery process. These continually feedback into each other informing new hypothesis that can be tested in order to be proven/disproven. This model is not always easy to implement out of the box and so I will share my own experiences in applying it in practice - what worked, what didn't and how the model can be adjusted to fit different teams and organisational environments.
Developer Experience
This document discusses developer experience (DX) and how to design for it. It begins with introductions of the presenters and defines DX as the experience developers have when using a product. It then discusses understanding developer pain points and personas, designing the developer journey, and using different interfaces like APIs, portals, and CLIs. The document outlines challenges in the design process like getting buy-in and measuring DX metrics. It argues that improving DX benefits business goals like enabling experiments, increasing flexibility, and attracting talent. It concludes that developers are also users and designers, and that DX is important to consider for business reasons.
When we design together
When we design together - Sabrina Mach, Ammara Gafoor and James Emmott
From three distinct perspectives, this talk will contend that design is an activity undertaken by everyone in a software development team. It occurs throughout the process of delivery — not only at the beginning or the end — and it is a powerful instrument for learning about and adapting to the problems our work seeks to solve, which is a shared responsibility. Making the best use of our multidisciplinary expertise in the activity of design requires forms of collaboration that are too often disrupted by the role-based silos that keep us separated and weaken the valuable contribution our diverse approaches could make to our collective efforts. If you care about accelerating time to market, improving customer experience, or building happy and productive teams, you will want to know why and how it matters that we believe ‘design is in everything that we do’.
Hardware is hard(er)
Hardware is hard(er): designing for distributed user experiences in IoT - Claire Rowland, www.clairerowland.com
Designing connected devices and hardware-enabled services is significantly more complex than pure software. There are more devices on which code can run, connectivity and data sharing patterns to consider, and often multiple and varied touchpoints for users to interact with. Pulling this all together into a coherent experience involves strong collaboration between design and engineering, and a systems thinking approach to UX. In this talk, we’ll introduce what designers need to know about the tech, what engineers need to know about UX for IoT, and how to facilitate the whole-collaboration needed to create great products.

Customer-centric innovation enabled by cloud
Working Backwards - Leading organisations achieve growth by marrying customer-obsession with a modern technology strategy. In this upcoming webinar, we’ve partnered with AWS to bring you exclusive insights from one of the world’s most innovative companies, Amazon.
Amazon's Culture of Innovation
The document discusses Amazon's culture of innovation. It emphasizes starting with the customer and working backwards to develop solutions. Amazon focuses on small, autonomous teams that are nimble and own their work. The company's leadership principles guide decision-making and encourage inventiveness, customer obsession, high standards, and long-term thinking to solve customer problems.
When in doubt, go live
The document discusses techniques for establishing shorter feedback loops between developing features and measuring user behavior, including:
1) Shadow traffic which runs new and old features simultaneously to get early feedback without users noticing a difference.
2) Visual reports which assess the quality of a feature through a report (e.g. HTML page) of key metrics.

As a tech leader at ThoughtWorks, a large part of my job involves recommending practices to our clients so they can build and deliver good quality software faster. In doing so repeatedly for many clients I have created a toolkit that contains practical advice from being on the ground. This is what we do, we know it works. When Julius Caesar entered Rome with his army by crossing the river Rubicon, he did something that couldn’t be undone ever again. In your journey as a leader, avoid mistakes that are difficult to correct later. Here are a set of practices that you want to adopt as soon as possible.
Error handling
Handling error conditions is a core part of the software we write. However, we often treat it as a second class citizen, obscuring our intent through abuse of null values and exceptions that make our code hard to understand and maintain. In the functional programming community, it is common to use datatypes such as Option, Either or Validated to make our intentions explicit when dealing with errors. We can leverage the compiler to verify that we are handling them instead of hoping for the best at runtime. This results in code that is clearer, without hidden path flows. We’ll show how we have been doing this in Kotlin, with the help of the Arrow library.
Your test coverage is a lie!
Mutation testing in software development surfaced in academia during the 70's and has recently seen a resurgence in popularity as a legitimate tool in your testing arsenal. In this session we review the conventional testing pyramid, modern approaches to testing software and look at how mutation testing can help fill in those blind spots.
Docker container security
The document discusses security challenges and best practices for Docker containers. It outlines risks at different stages of the container lifecycle from image development to deployment. Key risks include lack of isolation, complex ecosystems, and known vulnerabilities. The document recommends practices like using linting and scanning during development, restricting resources and access controls at deployment, and signing images from trusted sources to improve container security.
Redefining the unit
Mainframes handle 30 billion business transactions each day and 87% of all credit card transactions*, they are not traditionally associated with flexible, fail-fast development approaches. Can we bring the practices of agile, CI/CD and fully automated deployments to applications running on a mainframe? During our talk, we'll tell you a story about test automation; redefining the smallest testable unit of a program. And we'll discuss our learnings from introducing continuous integration and agile practices to the world of insurance and mainframes.

The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.
