App Engine/GWT overview (STLIC 02-10)jasonacooper

Google App Engine enables large and small businesses alike to host and run their web-based applications on Google's highly scalable infrastructure -- Google takes care of the maintenance, load balancing, and other server-side management tasks so you can focus on building out the core functionality of your web app. On the other end of the spectrum, Google Web Toolkit (GWT) enables developers to create rich, AJAX-enabled, web applications using a familar language (Java) and environment (Eclipse), which then get compiled to optimized JavaScript. This presentation will open with an introduction to Google's Eclipse plugin and demonstrate how to create a new servlet-based Java web application and deploy it to the cloud within 30 seconds -- all without leaving Eclipse! I'll then shift into a deep dive of both GWT and App Engine, showing how both work, how much they cost (hint: free to start!), the various features and services included for both, and more, and there should be plenty of time for Q&A afterward. You don't have to be entrenched in the Web 2.0 world to gain insight from this session. GWT makes it easy for businesses that are just starting to move their applications into the cloud, while maintaining an advanced feature set for those that have been there for years, and App Engine makes it especially easy to get your apps up and running in a scalable fashion. Whether you're just starting to investigate web development and cloud hosting providers or you are already a seasoned pro with other solutions, this session is for you.

Flutter Presentation Houston TechFest 2019Mohammad Azam

Flutter is a cross-platform mobile development SDK created by Google that allows building high-performance apps for both Android and iOS using a single codebase. It uses a declarative syntax and widgets that are rendered to native platform views. While most widgets work across platforms, Flutter also supports platform-specific widgets and code through platform channels. As Google owns Flutter, there is a risk it could discontinue the project in the future, though it currently appears to be actively developed and supported.

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?
