After several years of development, VNC support has been introduced as a new feature in Weston 12, which was released on May 17, 2023. This release includes a VNC backend that enables remote control through graphical desktop sharing. Notably, this marks the second Weston backend for remote connections with a graphical interface, as previous versions already supported RDP (Remote Desktop Protocol). The VNC backend in Weston 12 relies on two key libraries: Neat VNC and AML. It features TLS support and user authentication. Neat VNC is a VNC server library with a liberal license and a clean interface. AML, which stands for Andri's Main Loop, is a dependency for Neat VNC. Both of these projects were initiated by Andri Yngvason, and their source code is available on GitHub under the ISC License. Shortly after the release of Weston 12, the recipe in openembedded-core was updated to accommodate it. This update is included in Yocto release Nanbield 4.3 and Poky, which is the Yocto Project's reference distribution. It's important to note that the VNC backend is available as an optional configuration for PACKAGECONFIG, but it is not enabled by default. To build it, you'll need the Neat VNC and AML recipes, which have already been submitted by Leon Anavi to the meta-oe layer. Additionally, remember that you must explicitly enable TLS in neatvnc's PACKAGECONFIG to utilize the TLS support and user authentication in Weston's VNC backend. This presentation aims to demonstrate the practical use of the Yocto Project for building a core-image-weston with a VNC backend, enabling remote graphical desktop sharing. The demonstrations will showcase popular development boards, including the Raspberry Pi with the BSP layer meta-raspberrypi, Radxa ROCK 4 B with the BSP layer meta-rockchip, and Toradex Verdin i.MX8M Plus with Toradex and NXP BSPs. The presentation will provide a step-by-step walkthrough for generating certificates and establishing connections using Vinagre, an open-source VNC client for the GNOME Desktop. The presentation is suitable for anyone interested in Wayland and Weston, and no prior experience with VNC is required. This talk will illustrate how to set up the VNC backend in Weston and simplify the initial setup process for those interested in using it.

Individual microservices are relatively easy to develop, but managing a distributed system composed of microservices is never a simple task. Kubernetes helps, but it falls short of providing everything such a system needs. This is where the Istio Service Mesh comes in. Running microservices in production, you'll soon realize you want things like traffic splitting, automatic connection retries, timeouts and failovers, secure communication and authentication between your services, distributed metrics, tracing and logging. By introducing Istio into your architecture, you get all of that and more. And you get most of it without changing your code at all. In this talk, you'll see a demonstration of Istio in action and learn about the tricks that make its magic possible.

The Constrained Application Protocol (CoAP) is a new Web protocol standardized by the IETF. It is not a mere compression of HTTP, but a re-design from scratch following the REST architectural style. Thus, its features are tailored for Internet of Things (IoT) applications and machine-to-machine (M2M) scenarios with highly resource-constrained devices. While this makes CoAP very interesting for the Web of Things (WoT) initiative, it is still detached from the Web world of browsers and intuitive user interaction. We present the first attempts to unite these two worlds, so that everyday objects endowed with tiny, low-cost computing devices can become first class citizens of the Web. Our Copper (Cu) project brings CoAP support to the Web browser and has been out in the wild since late 2010. Thus, we were able to conduct a user study among industry and research developers who know both, Web-based CoAP and earlier proprietary protocols for networked embedded systems. The result shows that industry developers and those with longer experience agree even more that Internet protocols and patterns from the Web ease application development for tiny, resource-constrained devices.

This was presented at Augmented World Expo in Santa Clara (#AWE2017). A video of the live Natural Feature Tracking demo will be uploaded and linked from here soon. The key benefit of using AR in your web browser is how quick and easy it is to share. You can send a single web link through social media or email and the recipient can just tap on the link and it works. But up until recently this has not included Computer Vision based AR for a number of technical and market reasons. This presentation will position the web browser in the overall context of Computer Vision history, and we'll look at how this has evolved through developments including jsartoolkit.js, tracking.js and AR.js. We'll then dive deeper into the latest developments to show how OpenCV performs running in the browser and how this compares to native applications. This deep dive will compare the different feature detection/extraction algorithms and how they perform on some well known image data sets. The session will conclude with demos that show how this all works right now in over 2 Billion capable web browsers.

The presentation explores the development and application of artificial intelligence (AI) from its inception to its current status in the modern world. The term "artificial intelligence" was first coined by John McCarthy in 1956 to describe efforts to develop computer programs capable of performing tasks that typically require human intelligence. This concept was first introduced at a conference held at Dartmouth College, where programs demonstrated capabilities such as playing chess, proving theorems, and interpreting texts. In the early stages, Alan Turing contributed to the field by defining intelligence as the ability of a being to respond to certain questions intelligently, proposing what is now known as the Turing Test to evaluate the presence of intelligent behavior in machines. As the decades progressed, AI evolved significantly. The 1980s focused on machine learning, teaching computers to learn from data, leading to the development of models that could improve their performance based on their experiences. The 1990s and 2000s saw further advances in algorithms and computational power, which allowed for more sophisticated data analysis techniques, including data mining. By the 2010s, the proliferation of big data and the refinement of deep learning techniques enabled AI to become mainstream. Notable milestones included the success of Google's AlphaGo and advancements in autonomous vehicles by companies like Tesla and Waymo. A major theme of the presentation is the application of generative AI, which has been used for tasks such as natural language text generation, translation, and question answering. Generative AI uses large datasets to train models that can then produce new, coherent pieces of text or other media. The presentation also discusses the ethical implications and the need for regulation in AI, highlighting issues such as privacy, bias, and the potential for misuse. These concerns have prompted calls for comprehensive regulations to ensure the safe and equitable use of AI technologies. Artificial intelligence has also played a significant role in healthcare, particularly highlighted during the COVID-19 pandemic, where it was used in drug discovery, vaccine development, and analyzing the spread of the virus. The capabilities of AI in healthcare are vast, ranging from medical diagnostics to personalized medicine, demonstrating the technology's potential to revolutionize fields beyond just technical or consumer applications. In conclusion, AI continues to be a rapidly evolving field with significant implications for various aspects of society. The development from theoretical concepts to real-world applications illustrates both the potential benefits and the challenges that come with integrating advanced technologies into everyday life. The ongoing discussion about AI ethics and regulation underscores the importance of managing these technologies responsibly to maximize their their benefits while minimizing potential harms.
