Docker allows building portable software that can run anywhere by packaging an application and its dependencies in a standardized unit called a container. Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications. It groups containers that make up an application into logical units for easy management and discovery. Kubernetes can replicate containers, provide load balancing, coordinate updates between containers, and ensure availability. Defining applications as Kubernetes resources allows them to be deployed and updated easily across a cluster.

TrustArc Webinar: Consumer Expectations vs Corporate Realities on Data Broker...TrustArc

Most consumers believe they’re making informed decisions about their personal data—adjusting privacy settings, blocking trackers, and opting out where they can. However, our new research reveals that while awareness is high, taking meaningful action is still lacking. On the corporate side, many organizations report strong policies for managing third-party data and consumer consent yet fall short when it comes to consistency, accountability and transparency. This session will explore the research findings from TrustArc’s Privacy Pulse Survey, examining consumer attitudes toward personal data collection and practical suggestions for corporate practices around purchasing third-party data. Attendees will learn: - Consumer awareness around data brokers and what consumers are doing to limit data collection - How businesses assess third-party vendors and their consent management operations - Where business preparedness needs improvement - What these trends mean for the future of privacy governance and public trust This discussion is essential for privacy, risk, and compliance professionals who want to ground their strategies in current data and prepare for what’s next in the privacy landscape.

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.

3. WHY NODEJS: • Increase of usage of client side technologies • Responsive and Light Weight dev. Technologies Ex: Javascript, AngularJs, ionic and react WHY JAVASCRIPT AUTOMATION FRAMEWORKS: • NodeJs Usage • Automation is in application code – SDET roles • Automation along with developer’s code • Run BDD locally • Tools evolved: Webdriver IO, Nightwatch, protractor with CucumberJS.

4. NODEJS & SELENIUM:

5. MOST POPULAR JAVA SCRIPT BDD TEST FRAMEWORKS: •Protractor •Webdriverio •NightwatchJs

6. • Protractor: wrapper of WebDriverJs • Supports NodeJs • AngularJs element identification • Error reporting. • Inbuilt Test runner • Parallel Testing • Mobile- No support. PROTRACTOR

7. WEBDRIVERIO • NodeJs supported • WebDriverIO: W3C webdriver API • Supports CucumberJS • Inbuilt Runner • wdio.conf.js file • Cloud extension • Mobile- support to automate mobile Apps. • Community

8. WHY NIGHTWATCH • Supports Node.js • End-to-End (E2E) testing solution. • Built-in test runner. • Parallel Testing • Cross Browser Testing • Mobile Support • Continuous integration tool • Inbuilt screenshots • Inbuilt Assertion Library

9. CONT.... • Page Object Pattern • aliases for locators (@username) • Cloud extension • WebdriverIO apis • Easy to extend • Community

10. • Nightwatch: has it’s own implementation of the selenium WebDriver. And provides it’s own testing framework with a test server, assertions, and tools. • Framework- Can be used with other frameworks too, but can be especially useful in case you want to run functional tests not as part of other framework. • Syntax- looks the easiest and the most readable. WHAT NIGHTWATCH

11. COMPARISON OF TOOLS:

12. CONS OF NIGHTWATCH • Return value methods should only use call backs • Call backs should given for every steps

13. CONCLUSION: • HERO of the Javascript Frameworks because: • For an E2E Testing, the webdrive.io, is still evolving, Nightwatch will be a great and also is easy to use the framework • Also it has very good inbuilt Debugging mechanism. Hence, Nightwatch is good for the E2E Testing.
