The Harvard Business Review (HBR) thinks that Blockchain Technology has to power to keep data safe for consumers and businesses alike; because Blockchain provides a secure and immutable ledger, HBR says it represents the key to taking back privacy of data. “You can keep certified copies of identity documents, biometric test results, health data, or academic and training certificates online, available at all times, yet safe unless you give away your key. At a whole system level, the database is very secure.”

This slides show a more complex rollout real world scenario in combination of usb-based crypto keys used in parallel under linux and windows and cross-browser on windows too! Good thing is - no passwords must be stored on any of the authentication systems - no passwords can be stolen! ;-) Slides just give an overview over the overall architecture but was really working - see pictures on last slides - where the same certificate from the usb key is shown under linux and windows - still neat. Somehow not much seems to have changed since 2004 if one looks around - could still be applied in todays environments - the basics and it's still not wide spread nowadays. Note: Slides are historical versions from 2004, so not all shown hardware, protocols and/or drivers/software may be available or recommended for usage anymore. Today I would prefere OpenXPKI which forked of OpenCA and is an fully independent version by now close to 1.0 release this or next year! Check it out!

Felipe Fidelix, Business Development Manager (UK) at Platform.sh spoke at eZ Conference 2017 on Debugging Effectively in the Cloud. Debugging PHP can be quite fun, if you just know how to do it. But what happens when you need to go beyond that? In his presentation, Felipe explains in depth how to debug PHP and related services using not-often-explored techniques like filesystem monitoring, mysql proxy interception, system call tracing, debugging remotely and a lot more.

In the realm of real-time applications, Large Language Models (LLMs) have long dominated language-centric tasks, while tools like OpenCV have excelled in the visual domain. However, the future (maybe) lies in the fusion of LLMs and deep learning, giving birth to the revolutionary concept of Large Action Models (LAMs). Imagine a world where AI not only comprehends language but mimics human actions on technology interfaces. For example, the Rabbit r1 device presented at CES 2024, driven by an AI operating system and LAM, brings this vision to life. It executes complex commands, leveraging GUIs with unprecedented ease. In this presentation, join me on a journey as a software engineer tinkering with WebRTC, Janus, and LLM/LAMs. Together, we’ll evaluate the current state of these AI technologies, unraveling the potential they hold for shaping the future of real-time applications.

Created by Mozilla Research in 2012 and now part of Linux Foundation Europe, the Servo project is an experimental rendering engine written in Rust. It combines memory safety and concurrency to create an independent, modular, and embeddable rendering engine that adheres to web standards. Stewardship of Servo moved from Mozilla Research to the Linux Foundation in 2020, where its mission remains unchanged. After some slow years, in 2023 there has been renewed activity on the project, with a roadmap now focused on improving the engine’s CSS 2 conformance, exploring Android support, and making Servo a practical embeddable rendering engine. In this presentation, Rakhi Sharma reviews the status of the project, our recent developments in 2023, our collaboration with Tauri to make Servo an easy-to-use embeddable rendering engine, and our plans for the future to make Servo an alternative web rendering engine for the embedded devices industry.
