How we test antivirus software

Robust antivirus software is essential for protecting sensitive data in personal and business contexts. Different antivirus solutions vary in malware detection and overall protection. The ideal antivirus balances comprehensive coverage with system performance. Resources like AV-Comparatives and AV-Test provide impartial testing of antivirus capabilities, including real-world protection tests and evaluations of false alarms. Performance and customer support are critical factors in antivirus software evaluation. The impact on device speed and resource consumption is important, as is the quality of customer support for troubleshooting. Reliable support options enhance user satisfaction. Thorough testing of antivirus software is crucial due to the evolving tactics of cybercriminals. Not all antivirus solutions are equally effective, and rigorous evaluation helps identify subpar options and false positives. Free antivirus options may suffice for casual users, but premium versions often offer better features and protections. Meticulous testing ensures that security software meets its promises and helps users make informed decisions.

Postgres Pro OpenTelemetry сollector

Alexey has developed the pgpro-otel-collector, an OpenTelemetry collector by PostgresPro, designed to gather metrics and logs from PostgreSQL databases. It collects PostgreSQL metrics using an internal metrics library, OS-level metrics such as CPU and memory usage, and PostgreSQL logs in CSV and JSON formats. The collector includes internal processors for batch processing and supports exporting to OTLP-compatible backends like Elasticsearch and Prometheus. Installation is straightforward, requiring configuration of the Postgres connection and data destination. The collector can gather a range of PostgreSQL statistics and supports advanced features like CFS and pg_wait_sampling. Future enhancements include support for additional system views, integration with Shardman and BiHA, collection of custom query-based metrics, and a Grafana dashboard. Alexey's background includes experience with various monitoring tools and a focus on PostgreSQL, leading to the creation of this collector.

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.

Microsoft Debuts Windows Update Orchestration Platform For Updating All Apps From A Single Place

Microsoft has introduced the Windows Update Orchestration Platform, which aims to centralize the management of line-of-business (LOB) and third-party applications through a single interface, enhancing the app update process for developers and users. Currently in private preview, the platform invites developers to explore its features, which include eco-efficient scheduling, consistent notifications, centralized update history, and unified troubleshooting tools. Developers can integrate their applications using Windows Runtime APIs and PowerShell commands to manage various aspects such as registration and update definitions. The initiative addresses challenges like CPU and bandwidth spikes, conflicting notifications, and increased support costs faced by users and IT administrators.

Forced E-Waste PCs And The Case Of Windows 11’s Trusted Platform

The process of upgrading Windows operating systems was straightforward until Windows 11, which introduced a new requirement for a Trusted Platform Module (TPM), potentially rendering many capable PCs obsolete. The TPM is used for boot validation and storing biometric data, but it complicates data recovery and may lock out legitimate users. Users have found ways to bypass Windows 11's TPM and CPU restrictions, allowing installation on unsupported hardware. Microsoft’s enforcement of these requirements remains uncertain, raising concerns about system reliability and user access to updates. Many users are opting to stay on Windows 10 while advocating for continued support from developers.

Did Microsoft Change Windows 11 Requirements? – Here’s the Truth

Microsoft has not changed the official requirements for Windows 11 since its launch. Users need a compatible 64-bit processor (1GHz or faster with at least two cores), a minimum of 4GB of RAM, and 64GB of storage. Essential features include UEFI firmware that supports Secure Boot and TPM version 2.0, DirectX 12 compatible graphics with a WDDM 2.0 driver, and displays of at least 9 inches with a resolution of 720p. Microsoft allows experienced users to manually install Windows 11 on unsupported devices at their own risk, but this is not advisable due to potential issues. The strict requirements are intended to enhance security and performance. Users can check compatibility with the PC Health Check Tool. Microsoft will support Windows 10 until October 14, 2025, after which there will be no official support. For those whose systems do not meet the specifications, upgrading hardware or purchasing a new PC may be necessary.
