Big Data and New Challenges for DBAs (Michael Naumov, LivePerson) Hadoop has become a popular platform for managing large datasets of structured and unstructured data. It does not replace existing infrastructures, but instead augments them. Most companies will still use relational databases for transactional processing and low-latency queries, but can benefit from Hadoop for reporting, machine learning or ETL. This session will cover: What is Hadoop and why do I care? What do people do with Hadoop? How can SQL Server DBAs add Hadoop to their architecture?

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.
