Migrate Google Cloud SQL for PostgreSQL to Amazon RDS and Amazon Aurora using pglogical

PostgreSQL is a popular open-source relational database used by enterprise developers and startups, enabling rapid prototyping and supporting mission-critical applications. Amazon RDS for PostgreSQL and Amazon Aurora PostgreSQL-Compatible Edition facilitate easy setup, operation, and scaling of PostgreSQL deployments in the AWS Cloud, automating administrative tasks like software installation, storage management, and backups. The pglogical extension, compatible with PostgreSQL versions 9.4 and higher, allows for asynchronous replication and is supported on RDS for PostgreSQL and Aurora PostgreSQL from version 12. It uses a publisher/subscriber model for logical streaming replication. To migrate a PostgreSQL database from Google Cloud SQL to RDS for PostgreSQL or Aurora PostgreSQL, users must configure the primary database in Cloud SQL, create a PostgreSQL user with replication privileges, enable logical replication parameters, and create the pglogical extension. The RDS instance also requires a special user for replication, enabling logical replication parameters and creating the pglogical extension. Known limitations of pglogical include the inability to replicate primary key changes directly, the need to manually transfer extensions, and the lack of support for materialized views and large objects. Workarounds involve using surrogate keys for primary keys, manually creating extensions, and converting large objects to bytea columns or storing them in Amazon S3. DDL statements are not automatically replicated, but can be queued using the pglogical.replicate_ddl_command function.

Google Unveils Gemini Nano for On-Device AI in Android Apps

Google has updated the Gemini Nano APIs through the ML Kit, introducing new GenAI APIs that allow developers to perform on-device inference for generative AI capabilities in Android applications. These APIs enhance user privacy by executing all operations locally, eliminating cloud processing costs. Features include summarization of articles up to 3,000 words, proofreading for grammatical accuracy, rewriting text in various tones, and generating image descriptions. The GenAI APIs are optimized for Android devices using MediaTek Dimensity, Qualcomm Snapdragon, and Google Tensor platforms, including the Pixel 9 series and Samsung Galaxy S25. They operate without internet connectivity, ensuring rapid response times and improved performance for tasks like summarization and proofreading. The local processing also enhances privacy and security, protecting sensitive user information with safety protocols.

Supercharging vector search performance and relevance with pgvector 0.8.0 on Amazon Aurora PostgreSQL

The Amazon Aurora PostgreSQL-Compatible Edition has integrated support for pgvector 0.8.0, enhancing vector search capabilities significantly. This version achieves up to 9x faster query processing and delivers 100x more relevant search results compared to previous iterations. Key improvements in pgvector 0.8.0 include: - Up to 5.7x improvement in query performance for specific patterns. - Introduction of the iterative_scan feature, enhancing recall for filter queries requiring approximate nearest neighbor (ANN) index searches. - Improved cost estimation for more efficient query planning, allowing the selection of traditional indexes for complex filtered searches. - Flexible performance tuning with two modes for iterative_scan: relaxed_order and strict_order. Previous versions faced challenges with overfiltering, where combining vector similarity search with traditional SQL filters resulted in fewer results than expected. The HNSW indexing algorithm accelerates vector similarity searches by creating a multi-layered graph structure for efficient navigation. Iterative index scans in pgvector 0.8.0 improve query reliability and performance by applying filters during the scanning process, reducing false negatives and enhancing performance. The configuration options for iterative scanning include off, strict_order, and relaxed_order, with relaxed_order providing the best balance between performance and accuracy. In performance tests, pgvector 0.8.0 demonstrated substantial improvements across various query patterns, with significant enhancements in result completeness and recall. The database can now efficiently handle enterprise-scale applications, such as e-commerce and recommendation systems, with high performance and result quality even as product catalogs expand. Best practices for deploying pgvector 0.8.0 include using HNSW with recommended parameters, creating additional indexes on commonly filtered metadata columns, and tuning query parameters based on specific use cases. Operational best practices involve using Graviton4-based instances for optimal performance, monitoring and tuning slow vector queries, and considering partitioning for very large tables.

Bring your PWA closer to users with App Actions on Windows

App Actions on Windows have expanded to include Progressive Web Apps (PWAs) starting from Edge version 137. Developers can now publish their PWAs to the Microsoft Store, allowing for enhanced user interactions. App Actions enable users to access key features of an app directly from their current context, reducing distractions from switching between applications. For example, the note-taking app Goodnotes allows users to send text directly to the app without toggling windows. Developers can integrate App Actions into their Microsoft Store PWAs by defining an Action manifest, setting up a custom protocol handler, configuring the app as a share target, and packaging the app for the Microsoft Store using PWABuilder. Optionally, developers can define a PWA launch handler and test actions using the App Actions Testing Playground.

Vietnam to block messaging app Telegram over ‘anti-state’ contents

The Vietnamese government has instructed telecommunications companies to block the Telegram messaging app, citing security concerns and the dissemination of "anti-state" content. This directive was issued by the Telecommunications Department and requires service providers to report compliance by June 2. A document from the Ministry of Public Security indicated that 68% of approximately 9,600 Telegram channels and groups in Vietnam were classified as “bad and toxic,” involved in activities such as anti-state messaging, fraud, and drug trafficking. The government referenced Article 9 of the Telecommunications Law and Decree 147 to justify the ban, claiming Telegram had not complied with regulations. Despite the ban, Telegram remained accessible in Vietnam as of the report date. Telegram expressed surprise at the government's actions and confirmed it is responding to legal requests from Vietnam.

How to turn off antivirus

Antivirus software is crucial for digital security, providing protection against malware threats. Users may need to disable antivirus temporarily for reasons such as system resource consumption, particularly during resource-intensive tasks like gaming, or to bypass false positives when installing applications. Disabling antivirus software poses risks, especially when browsing the internet, as even legitimate sites can be compromised. Precautions to take when disabling antivirus include disconnecting from the internet, avoiding USB drives, using trusted networks, closing non-essential applications, verifying the legitimacy of downloaded files, and limiting browsing to secure websites. Users should promptly re-enable their antivirus after completing necessary tasks.

What brands can learn from Minecraft’s Chicken Jockey

Brands are increasingly required to engage with customers in digital spaces, with platforms like Roblox attracting 90 million daily active users. 56% of Gen Z prioritize styling their avatars over their own appearance, highlighting the need for brands to adapt to virtual environments. The gaming sector provides opportunities for product testing using digital twin technology, allowing brands to simulate scenarios and analyze data for trend forecasting. Retailers like Temu, Shein, and TikTok are rapidly creating products in response to trends, necessitating a shift from traditional six-month development cycles to real-time supply chains. Demand spikes can arise from various sources, and without a robust Order Management System (OMS), businesses risk losing sales. Accurate, real-time inventory visibility is crucial for managing demand spikes and anticipating future needs. Nike has launched Nikeland on Roblox for product testing and consumer engagement, while Snapchat offers AR features for virtual try-ons, allowing brands to gauge interest before physical launches. The intersection of gaming and commerce presents unique opportunities for innovative consumer engagement.
