Ring’s Billion-Scale Semantic Video Search with Amazon RDS for PostgreSQL and pgvector

Users of Ring's semantic video search can quickly find specific moments in video data, such as "a dog in my backyard" or "a package delivery," using a system that employs PostgreSQL and pgvector for video data handling. The system utilizes vector embeddings to represent visual content, allowing for efficient storage and similarity searches. When a user queries a term, the system converts it into a vector to retrieve similar video frames in under two seconds. Ring's video search operates on a global scale, processing billions of read requests daily across four continents and nine AWS regions, with strict latency requirements for millions of users. Key metrics include storing 100–200 billion embeddings, generating approximately 2 billion new embeddings daily, and maintaining a data footprint of 140–150+ TB across three PostgreSQL clusters.

Best Minecraft Music Discs and Why Players Love Them

Minecraft features 13 unique music discs that players can collect, each with its own sound and style, which can be played on virtual jukeboxes. These discs can be found in various locations such as hidden chests, unexpected drops, and dungeons. Notable discs include “otherside,” “Pigstep,” “cat,” “stal,” and “11,” each offering distinct musical experiences that contribute to the game's atmosphere. As of 2023, Minecraft has 62 million monthly players. The original soundtrack, composed by C418, enhances the emotional essence of the game. Players often create dedicated jukebox rooms, and the mechanics of acquiring discs involve specific strategies, such as using skeletons to defeat creepers. The “otherside” disc is found in castle and dungeon chests, while “Pigstep” is exclusive to Bastion Remnants in the Nether.

Have a Samsung phone and PC? You need the new Galaxy Connect Windows app

The user expanded their Samsung ecosystem with a Galaxy Book 4 Edge and tested the Galaxy Connect application, which includes four features: Continue on other devices, Storage Share, Multi Control, and Second Screen. Multi Control allows users to connect their Samsung phone or tablet as a secondary display, enabling seamless control of the mobile device from the primary display. The Second Screen feature lets users utilize a Galaxy tablet as a wireless display for their Windows computer, reducing lag by connecting directly. Storage Share provides access to files on Samsung devices from the PC's File Explorer, and the Continue on other devices feature syncs the clipboard for easier two-factor authentication. Users with ARM-based PCs may face limitations, and some without Intel network adapters have reported issues with Galaxy Connect's functionality.

Why Postgres wants NVMe on the hot path, and S3 everywhere else

Why Postgres wants NVMe on the hot path, and S3 everywhere else

Efforts to merge storage roles into a single solution are ongoing, particularly with Amazon S3's durability and cost-effectiveness. In PostgreSQL, achieving a durable commit requires flushing the Write-Ahead Log (WAL) before signaling transaction completion, which can take tens of microseconds on high-performance NVMe drives but extend to milliseconds on slower storage. This latency impacts Online Transaction Processing (OLTP) systems and user response times. Benchmark studies show that systems with faster local storage outperform those with slower alternatives as workloads exceed memory capacity. The fsync operation in PostgreSQL is a commitment rather than a simple write, with enterprise-grade SSDs performing better due to power-loss protection. Read operations also face challenges, as PostgreSQL's need for small, latency-sensitive reads conflicts with S3's design for larger, higher-latency requests. As the working set exceeds memory, storage latency becomes a critical performance factor. Modern managed PostgreSQL systems typically do not place object storage in the critical commit path, instead maintaining a fast log or cache close to the database while relegating colder data to remote storage. Recent PostgreSQL developments, such as asynchronous I/O support in version 18, aim to leverage fast storage more effectively. S3 is valuable for tasks like WAL archiving and backups, but these should be kept separate from the commit path to avoid resource contention. The solution involves using both NVMe and S3, with fast storage managing commits and cache misses, while object storage handles archives and backups. PostgreSQL performs best when hot and cold storage functions are clearly delineated.

Deploy Postgres and MySQL databases with PlanetScale + Workers

Cloudflare has deepened its partnership with PlanetScale to enhance the developer experience by providing Cloudflare Workers with access to Postgres and MySQL databases. Users will be able to create PlanetScale databases directly from the Cloudflare dashboard and API, with billing handled through their Cloudflare accounts. Cloudflare credits can be applied towards PlanetScale databases. The integration allows developers to link their PlanetScale accounts and create Postgres databases from the Cloudflare dashboard. Starting next month, new PlanetScale databases will be billed directly to Cloudflare accounts. The integration uses Hyperdrive for database connectivity, managing connection pools and query caching. PlanetScale offers performance and reliability, allowing developers to choose between Postgres and Vitess MySQL. Cloudflare users can deploy PlanetScale databases directly from Cloudflare, with features like query insights and usage breakdowns included. A single node on PlanetScale Postgres starts at a specified monthly rate. Developers can configure Workers to minimize latency by placing them near the primary database, with future plans to automate this process. Currently, billing for existing PlanetScale databases is processed through PlanetScale, but new databases will be billed through Cloudflare starting next month. Further enhancements and API integration are planned, with community feedback encouraged.

Pragmata PC performance tested: 18 GPUs take us to the Moon

Capcom's new sci-fi shooter, Pragmata, features a narrative centered on Hugh, the last survivor of a lunar rescue mission, and Diana, an android with hacking abilities, as they navigate a 3D-printed lunar facility. The game has locked out Radeon support, which has raised concerns about business motivations over technical limitations, despite the Radeon RX 9000-series cards performing well. AMD users can access FSR 3 upscaling, with FSR 4 available for RX 9000-series cards, while older RX 7000- and RX 6000-series cards are limited to FSR 3. The game supports various rendering modes, including rasterization, ray tracing, and path tracing. At 1080p, ray tracing performs well on most hardware, but at 1440p and 4K, higher VRAM cards show better performance. Path tracing requires upscaling and frame generation for optimal playability, with DLSS Frame Generation providing significant benefits for Nvidia users. The RTX 3070 lacks DLSS frame generation support, necessitating FSR 3 for testing, which results in lower image quality compared to DLSS. Overall, Pragmata is designed to leverage advanced graphics technologies, particularly for GeForce RTX 40- and 50-series card owners, while also offering a solid experience for AMD users, albeit with some limitations.
