The Search Stack That Nearly Broke Us — Until We Did This

The initial architecture for the finlight.me real-time financial news API utilized Postgres full-text search, which was effective for early needs but faced limitations as article volume increased. Key challenges included performance degradation due to the inability to combine GIN indexes with regular B-Tree indexes, leading to slow query performance, especially with complex user queries and pagination. The decision was made to transition to OpenSearch for its optimized search capabilities while retaining Postgres as the source of truth for data integrity. Testing with OpenSearch revealed the need for production-grade resources, which led to a successful deployment that improved search response times significantly. The current architecture separates ingestion, storage, and retrieval responsibilities, with Postgres managing data storage and OpenSearch handling user-facing search queries. Regular snapshotting and thoughtful index management ensure resilience and scalability.

CISOs should re-consider using Microsoft RDP due to password flaw, says expert

Microsoft has clarified that a feature in its operating system, which allows at least one user account to log in after prolonged offline periods, is a deliberate design choice and not a security vulnerability. The Remote Desktop Protocol (RDP) caches the last set of credentials used to prevent administrators from being locked out, but this can lead to complications if credentials are changed, potentially allowing unauthorized access if outdated credentials are exploited. Johannes Ullrich from the SANS Institute emphasized the importance of securing RDP and recommended robust authentication measures and isolation of RDP endpoints to mitigate risks.

Windows RDP has a major security problem, and Microsoft has refused to do anything about it

A security flaw in Windows RDP allows previously revoked credentials to remain functional after a password reset, enabling users to access their PCs with old passwords. Microsoft does not classify this issue as a bug, stating it is an intentional design to ensure at least one user account can always log in. This behavior is not flagged by Microsoft Defender, Azure, or Entra ID, and the company's documentation lacks clarity on the matter. Microsoft has been aware of this issue since at least August 2023 but has chosen not to modify the code, citing potential compatibility issues.

Oblivion Remastered PC: impressive modernisation blighted by dire performance problems

The Elder Scrolls 4: Oblivion Remastered utilizes an Unreal Engine 5 wrapper to enhance the original game, but it carries over some of the original's issues and suffers from significant performance challenges, including frequent stuttering. Digital Foundry analyzed the remaster against the original 2006 version, highlighting advancements in graphics but also noting that the remaster struggles with limited polygon budgets and basic effects. The remaster's performance is inconsistent, especially on mid-range CPUs, leading to poor experiences even on high-end hardware. Disabling hardware RT-based Lumen global illumination can improve performance by about 35%, but at the cost of visual quality. Lowering settings yields only marginal performance improvements, and the game fails to deliver an attractive experience compared to the original. A recent patch did not resolve the stuttering issues, indicating that fundamental CPU-related problems remain unaddressed.

Pools across the sea: how Hyperdrive speeds up access to databases and why we’re making it free

Cloudflare has made Hyperdrive available on the free plan of Cloudflare Workers, allowing developers to create high-performance global applications that connect to SQL databases. Hyperdrive simplifies database connectivity by using existing drivers and connection strings, reducing the need for extensive refactoring. It has been adopted by Cloudflare's engineering teams for various functions, demonstrating its effectiveness in addressing common challenges in application development. Hyperdrive significantly improves performance, with a benchmark showing latency reduction from 1200 ms to 500 ms when using Hyperdrive instead of a direct connection, and further to 320 ms with caching enabled. It employs transaction-mode connection pooling to efficiently manage database connections, minimizing overhead and ensuring optimal performance for serverless applications. Hyperdrive's architecture includes a split connection approach that reduces latency by conducting necessary round trips over shorter distances. It also features a regional pool strategy for selecting data centers based on the inferred location of the Worker, optimizing connection latency. The system includes a dual-layer caching strategy to enhance query performance and reduce load on the origin database. Developers can easily start using Hyperdrive by executing a simple command or using a dashboard to set up a sample Worker application with their existing Postgres database.
