The document summarizes a research paper on securing cloud data through encryption and distribution of encrypted data across multiple cloud servers. It proposes a method called "Bastion" that generates private and signature keys to restrict access to encrypted data even if an attacker obtains the encryption key. The Bastion method distributes encrypted data blocks across multiple servers so that an attacker would need to compromise all servers to recover the original plaintext data. Experimental results showed Bastion improved security compared to existing schemes and introduced minimal overhead. The conclusion states that Bastion is well-suited for multi-cloud storage environments and enhances data security when encryption keys are obtained by attackers.Quantum AI: Where Impossible Becomes Probable

Let's talk about our history. How we started the project with a small vector database of less than 2 million records. Later, we received a request for +100 million records, then another +100... And so gradually we reached almost 1 billion. Standard tools were quickly running out of steam - we were running into performance, index size, and very limited resources. After a long series of trials and errors, we built our own low-cost cluster, which today stably processes thousands of queries to more than 1B vectors.AI vs Human Writing: Can You Tell the Difference?

In todays dynamic digital landscape, ensuring the quality and dependability of web applications is essential. While Selenium has been a longstanding solution for automating browser tasks, the integration of WebdriverIO (WDIO) with Selenium and JavaScript marks a significant advancement in automation testing. WDIO enhances the testing process by offering a robust interface that improves test creation, execution, and management. This amalgamation capitalizes on the strengths of both tools, leveraging Seleniums broad browser support and WDIOs modern, efficient approach to test automation. As automation testing becomes increasingly vital for faster development cycles and superior software releases, WDIO emerges as a versatile framework, particularly potent when paired with JavaScript, making it a preferred choice for contemporary testing teams.9-1-1 Addressing: End-to-End Automation Using FME

This session will cover a common use case for local and state/provincial governments who create and/or maintain their 9-1-1 addressing data, particularly address points and road centerlines. In this session, you'll learn how FME has helped Shelby County 9-1-1 (TN) automate the 9-1-1 addressing process; including automatically assigning attributes from disparate sources, on-the-fly QAQC of said data, and reporting. The FME logic that this presentation will cover includes: Table joins using attributes and geometry, Looping in custom transformers, Working with lists and Change detection.Securing Account Lifecycles in the Age of Deepfakes.pptx
