“It’s a trap” - a call or feeling we all might be familiar with, not only when it comes to Star Wars. It’s signalizing a sudden moment of noticing imminent danger. This situation is an excellent allegory for an unpleasant realization in testing. Imagine having the best intentions when it comes to testing but still ending up with tests failing to deliver you any value at all? Tests who are feeling like a pain to deal with?When writing frontend tests, there are lots of pitfalls on the way. In sum, they can lead to lousy maintainability, slow execution time, and - in the worst-case - tests you cannot trust. But it doesn’t have to be that way. In this session, I will talk about developers’ common mistakes (including mine), at least from my experience. And, of course, on how to avoid them. Testing doesn’t need to be painful, after all.

Sustainable web design is an approach to designing digital products and services that are conscious of lowering carbon emissions by becoming more efficient. The internet may be digital, but it runs on electricity, much of which is still produced by fossil fuel.The choices we make in designing digital Products, from UX and development to the servers we use can have a carbon cost and can contribute to global Greenhouse gases. To help with this topic, in August last year, W3C released first draft of Sustainable Web Guidelines and they have been evolving and helping community ever since. As a part of W3C Sustainable Web Community Group, I got to work on these guidelines and would love give a sneak peak into its development process and show how to best leverage them to design digital products that put people and planet first.

In a world where managers want to compare multiple KPIs here and now, the ability to quickly get the right data in front of the end user is critical. However, frequent data updates cause other records to become outdated or unnecessary. Extracting interesting information from such an append-only data lake requires complex SQL queries that include windowing functions and/or join operations. As the system grows, queries become longer and longer, and time is money. This begs the question of how to cost-effectively update or delete unwanted records from the data lake to exclude them from queries. Based on my own project experience as an architect, I will show which tools in the AWS cloud can be used to answer this question. I will also share best practices for designing serverless reporting systems in the cloud.

Software supply chain attacks can be catastrophic. For instance, the 2020 SolarWinds hack was considered an attack against the entire government and private sector of the United States of America.

NuGet is vulnerable by design in its default configuration.First, you will see how typosquatting and dependency confusion attacks can compromise .NET supply chains that rely on the default NuGet configuration. Second, I will show how you can secure your NuGet configuration to thwart evil hackers.This talk will assume attendees have some basic knowledge of NuGet and MSBuild.

Dapr (Distributed Application Runtime, an open-source CNCF project) provides developers with common cloud-native capabilities for reliable service invocation, asynchronous messaging, cross-cutting concerns such as observability, security, resiliency, and more - accessed via standardized APIs that decouple application code from the underlying infrastructure. This allows for implementing distributed systems in a language and platform-independent manner, according to best practices and patterns.Operating on this higher level of abstraction brings significant benefits but involves important trade-offs; in this session, Marc Klefter will explore these aspects by guiding you through the building blocks of Dapr and how it solves typical cloud native application challenges, adoption strategies for greenfield and migration (i.e. moving away from direct integration with vendor-specific services) scenarios, and the organizational implications for application and platform engineering teams.

We are surely all aware of the carbon footprint - even that of the IT. With Green Coding, we try to reduce the impact of our software on the climate as much as possible. And that's great!But is the effort really worth the few kilos of carbon saved? Can we even reduce the footprint enough to make a significant difference?Why don't we think differently? Let's talk about the handprint instead!It's about what other options we developers have to make a difference, other than just spending hours tweaking our code. There's more to it than you might think!

Lots of teams are struggling with automated end-2-end tests as they are a real challenge to write and to maintain.

Who hasn't experienced this: when you talk about the architecture of software projects and what works well or badly in them, you recognize similarities regardless of the industry in question. These patterns are now commonplace in software development. Based on an excellent presentation by Stefan Tilkov, we have collected some of these architectural antipatterns together with the case studies in which they have occurred in recent years. At this point, I would like to present the resulting catalog and discuss some cloud-relevant antipatterns. But this is just the beginning - we want to expand this as a community project. I would therefore be happy to talk to you about these and other antipatterns after the presentation and also at the conference.

We have been developing software in an agile way for over twenty years now. Methods like TDD, DDD, CI/CD and Scrum help us to build digital products right. Furthermore, products have been released operated and measured for more than ten years guided by DevOps principles. While it is imported to build a product right, it's even more important to build the right product. Because, as Peter Drucker said, there's nothing quite so useless as doing with great efficiency something that should not be done at all. Product Discovery helps us to find the right product.But dev and ops people today often feel they can't work with product management and design on Product Discovery as equals partners. I'll give you a 101 on product discovery techniques. That will enable you to take an active part in this discussion.

The basic premise is that by making our service landscape more modular we increase innovation speed at the company level. Different factors while taking that decision. Coupling, Cohesion, Encapsulation. Lets make trade-offs between them when making design decisions.Lets take a real problem and design a system and measure its modularity.Pure maths can help us making faster decisions, hence increase innovation.Unfortunate: We use the term microservicesnano services / functions | lambdasit’s not about the size of the boat, but about the motion in the ocean.Smaller is not (perse) betterReflect on cost vs benefitSo how can we design better?What is modulith?Perfect marriage of a monolith and boundaries of a microservice is clearly a golden bullet.Results:system ~ bounded contextsystem != deployablesystem >= 1 deployablestrong cohesive deployables loosly coupled deployablesbelong togetherexposed under a single apiisolation by system

For the last decades, automotive software has been minimalistic and low-profile. That era has passed, and modern cars have rapidly evolved into what can be described as 'tablets on wheels.' Nowadays, all car functions, such as the engine, door locking, or lane assist, are operated by a complex network of embedded software. This system is managed by a vast number of different electrical control units, making it challenging to update and maintain.In recent years, Linux providers have announced in-vehicle operating systems based on the Linux Kernel. The goal is to consolidate software onto a common platform, ultimately utilizing software containers in cars. This opens up possibilities to make development more flexible and enables even DevOps. However, the integration of physical interfaces, such as internal bus systems, temperature sensors, and door actuators, create new security challenges.Not familiar with the automotive world? Don't panic - jump in and enjoy the hitchhiker's guide!

Code peer reviews is one of the most mature techniques for quality assurance in software development, first published about as early as the '70s. Yet, we often find they are not used, because people deem them too costly or ineffective. An assessment that directly contradicts our own gut feeling after employing code reviews from day one of our 16-year product history. But what's the truth of it? What are the benefits of code review? Which kinds of issues do they uncover? How do they impact our code? Which factors, such as the reviewing person, influence those results? And ultimately: how much additional time do they actually require?To answer these and other questions, we analyzed 16 years worth of data from the development of our product Teamscale, from the first prototype to today's enterprise-ready application with 1.5 million SLOC. In my talk, I share our insights and conclusions.Spoiler alert: We still review all our changes and now feel even better about it ;)

Modern software development is not just about coding; it’s about the orchestration and automation of development, assembly, and operation of software. Today, the average software developer spends just 20% of their time coding - the rest of the time is spent in collaboration with marketing, product, design and other members of the software team, responding to incidents, answering questions, and more. Many developers report that coding is their favorite part of their job and yet to date, most generative AI innovation has focused on code assistants. In this session, Suzie will share Atlassian’s vision for the future of AI, why she thinks it should be focused on improving collaboration and reducing complexity so developers can get back to what they love doing - coding and problem solving.

Reading assembly code is an important skill for debugging and optimization. Is there a bug in a 3rd party framework that you don't have the source code for? Are you calling into a system framework and it does not behave the way you expect? Do you want to understand the code the compiler generates, depending on the optimization level you choose? I have done all of these things more often than I would have liked in the past and I had acquired a solid understanding of x86 assembler code over the years. All was well until, suddenly, I had an ARM machine on my desk.If you are, like me, using ARM machines a lot and always wanted a gentle introduction to ARM assembler code, this is the talk for you.
