Kotlin Multiplatform in Action - Alexandr Pogrebnyak - IceRockDevDroidConTLV

Kotlin Multiplatform in Action is a presentation about IceRock's experience using Kotlin Multiplatform over the past year. Some key points: - IceRock has been developing mobile apps for 5 years and has seen benefits from using Kotlin Multiplatform to share 50% of code on average between Android and iOS apps, reducing development time and costs by 1.5x. - Kotlin Multiplatform allows sharing of presentation logic, domain logic, and data access code while still using platform-specific code for views and platform integration. This avoids much of the duplication of traditional multi-platform approaches. - IceRock has released moko-widgets, a set of multiplatform UI widgets, to make building

Droidcon Nigeria 2021 - Still Sleeping on KMM? Emmanuel Kehinde

The document discusses Kotlin Multiplatform Mobile (KMM), which allows sharing code across Android and iOS platforms. It provides an overview of what KMM is and isn't, how it works using expect/actual keywords and interfaces, integration methods, requirements, documentation, sample projects, libraries, benefits and challenges. Key points are that KMM allows a single codebase for business logic across platforms, saves development time, provides a single source of truth, but concurrency and debugging can be challenging.

Tools and Process for Streamlining Mac DeploymentTimothy Sutton

This presentation was given at the MacSysAdmin 2016 conference in Gotebörg, Sweden. Session description follows: Apple’s popularity and their approach to selling hardware is revolutionizing how IT gets that hardware into the hands of its users. Every year’s new Macs and OS X bring new changes, which doesn’t leave much time for the repetitive setup tasks that are involved in getting machines ready for users (or our testing!). It’s easy to fall behind on OS support, but we have no choice but to support the latest. The Mac sysadmin community is blessed with so many great open-source tools at its disposal for deploying and managing Macs. We'll look at approaches and tools for automating these to bring speed, consistency and sanity to our deployment processes. By being more systematic, we can be more agile, and reclaim time to work on more important problems. This session will focus on OS X hardware and tools, but the approaches discussed apply equally to iOS devices.

Scaling up development of a modular code baseRobert Munteanu

OSGi offers developers excellent tools for creating modular applications. We have come to have a good understanding of the runtime impact of modularity, but less has been spoken of the impact of modularity on the development process. This talk will discuss the details of moving a large OSGi project from a single monolithic codebase to multiple repositories in terms of the development process. We will present the impact of modularisation on source control, continuous integration, code reviews, IDEs and public discussion on chat/email. After this talk attendees will have a better understanding of the way they can improve their development process when dealing with OSGi or other kinds of modular applications.

AI Changes Everything – Talk at Cardiff Metropolitan University, 29th April 2...Alan Dix

Talk at the final event of Data Fusion Dynamics: A Collaborative UK-Saudi Initiative in Cybersecurity and Artificial Intelligence funded by the British Council UK-Saudi Challenge Fund 2024, Cardiff Metropolitan University, 29th April 2025 https://alandix.com/academic/talks/CMet2025-AI-Changes-Everything/ Is AI just another technology, or does it fundamentally change the way we live and think? Every technology has a direct impact with micro-ethical consequences, some good, some bad. However more profound are the ways in which some technologies reshape the very fabric of society with macro-ethical impacts. The invention of the stirrup revolutionised mounted combat, but as a side effect gave rise to the feudal system, which still shapes politics today. The internal combustion engine offers personal freedom and creates pollution, but has also transformed the nature of urban planning and international trade. When we look at AI the micro-ethical issues, such as bias, are most obvious, but the macro-ethical challenges may be greater. At a micro-ethical level AI has the potential to deepen social, ethnic and gender bias, issues I have warned about since the early 1990s! It is also being used increasingly on the battlefield. However, it also offers amazing opportunities in health and educations, as the recent Nobel prizes for the developers of AlphaFold illustrate. More radically, the need to encode ethics acts as a mirror to surface essential ethical problems and conflicts. At the macro-ethical level, by the early 2000s digital technology had already begun to undermine sovereignty (e.g. gambling), market economics (through network effects and emergent monopolies), and the very meaning of money. Modern AI is the child of big data, big computation and ultimately big business, intensifying the inherent tendency of digital technology to concentrate power. AI is already unravelling the fundamentals of the social, political and economic world around us, but this is a world that needs radical reimagining to overcome the global environmental and human challenges that confront us. Our challenge is whether to let the threads fall as they may, or to use them to weave a better future.

Building 10x Organizations with Modern Productivity Metrics 10x developers may be a myth, but 10x organizations are very real, as proven by the influential study performed in the 1980s, ‘The Coding War Games.’ Right now, here in early 2025, we seem to be experiencing YAPP (Yet Another Productivity Philosophy), and that philosophy is converging on developer experience. It seems that with every new method we invent for the delivery of products, whether physical or virtual, we reinvent productivity philosophies to go alongside them. But which of these approaches actually work? DORA? SPACE? DevEx? What should we invest in and create urgency behind today, so that we don’t find ourselves having the same discussion again in a decade?
