Multi-tenant vector search with Amazon Aurora PostgreSQL and Amazon Bedrock Knowledge Bases

The article discusses the implementation of a multi-tenant vector store using Amazon Aurora PostgreSQL-Compatible Edition and Amazon Bedrock Knowledge Bases. It outlines a scenario where users request home surveys, and surveyors update findings stored in an Amazon S3 bucket. The process involves converting documents into vector embeddings for enhanced natural language queries through the Retrieval Augmented Generation (RAG) technique. Key steps include: 1. Ingesting data from S3 into Amazon Bedrock Knowledge Bases. 2. Using an embeddings model to convert documents into vector embeddings. 3. Storing vector embeddings, data chunks, and metadata in Aurora with pgvector. 4. Submitting natural language queries that are transformed into embeddings for retrieval from the vector store. 5. Forwarding relevant documents to a large language model for response generation. To set up the vector store, prerequisites include access to an Amazon Aurora PostgreSQL-compatible database, Amazon S3 for document storage, and Amazon Bedrock for managing knowledge bases. The article provides SQL commands for creating the necessary schema, vector table, and index in Aurora, as well as instructions for ingesting data and ensuring multi-tenant data isolation through metadata filtering. Best practices for deploying a multi-tenant vector store include optimizing chunk size, evaluating embedding models, and monitoring query performance. The article emphasizes the benefits of fully managed solutions to reduce operational complexity.

Your Android phone could have stalkerware. Here’s how to remove it

Consumer-grade spyware applications, often referred to as "stalkerware" or "spouseware," pose significant risks to Android users by monitoring private messages, photos, phone calls, and real-time locations without consent. These apps are typically downloaded from outside the Google Play Store and can be stealthily installed, often disappearing from the home screen. Stalkerware exploits legitimate Android features, leading to unusual phone behavior such as excessive heat, sluggish performance, or unexpected data usage. To address spyware, users should establish a safety plan and trusted support before attempting removal, as this could alert the installer. Google Play Protect should be enabled to scan for harmful apps. Users should check for unfamiliar apps in accessibility services, review notification access for third-party applications, and inspect device admin app settings for unrecognized applications. Even hidden stalkerware apps will appear in the list of installed applications, which can be accessed through the settings menu. Strengthening device security, such as enhancing lock screen passwords and using two-factor authentication, is recommended. Resources for support include the National Domestic Violence Hotline and the Coalition Against Stalkerware.

I love Steam Link, but this new streaming app is better in every way

Razer's Nexus app is a new alternative to Steam Link for local game streaming, featuring remote play functionality that requires the installation of both the Nexus app and the Razer Cortex app on the desktop. The setup process takes about five minutes, slightly longer than Steam Link. The Nexus app is based on Moonlight, an open-source streaming software, and offers enhanced performance by automatically adjusting settings for high-refresh-rate displays. It works well with PC Game Pass titles but has limitations with non-Steam games, which may require manual control adjustments. Users must create an account, and the app promotes paid games and includes display ads. Alternatives like Artemis/Apollo exist but require more complex installation.
