PostgreSQL 18 on Amazon Aurora and Amazon RDS: Performance enhancements

PostgreSQL 18 addresses common performance challenges for users, including managing query performance across composite indexes, diagnosing memory spills in materialized Common Table Expressions (CTEs), and upgrading major versions without plan regressions. Key enhancements include skip scan optimization for multicolumn indexes, improved EXPLAIN functionality, and optimizer statistics that persist through major version upgrades. Skip scan optimization allows PostgreSQL to efficiently utilize multicolumn B-tree indexes even when leading columns are not specified in the WHERE clause, significantly improving query performance. The EXPLAIN command has been enhanced to include buffer statistics by default, providing deeper insights into query execution and resource usage. PostgreSQL 18 also introduces visibility into the storage of materialized nodes in query plans, indicating whether intermediate results were stored in memory or spilled to disk. A new metric, Index Searches, has been added to EXPLAIN ANALYZE output, indicating how many times the database traversed the index tree during query execution. Additionally, Self-Join Elimination (SJE) automatically detects and removes unnecessary inner joins of a table to itself, optimizing query performance. The autovacuum mechanism has been improved with the introduction of autovacuum_vacuum_max_threshold, which caps the number of dead tuples that can accumulate before autovacuum triggers a VACUUM, addressing issues with large tables. The vacuum_truncate parameter provides a server-wide control point to disable VACUUM’s file truncation behavior, reducing locking issues on busy systems. PostgreSQL 18 also separates the allocation of autovacuum worker slots from their usage, allowing for dynamic adjustments to autovacuum_max_workers without requiring a server restart. Finally, new columns in pg_stat_all_tables track cumulative time spent on maintenance operations, providing better insights into maintenance overhead for each table.

Что такое торрент, как он работает и можно ли им пользоваться

Downloading a Linux distribution from the official website typically takes about half an hour, but during high-demand periods, such as new Ubuntu releases, speeds can drastically decrease due to server overload. Torrents, which use a peer-to-peer file-sharing protocol, allow users to download and share data simultaneously, reducing the load on a single server. Torrents operate by enabling direct exchanges between users through the BitTorrent protocol, where files are divided into smaller pieces and downloaded in parallel from multiple sources. Key terms include peers (users with parts of the file), seeds (users who have fully downloaded the file), .torrent files (metadata files), and magnet links (text-based alternatives to .torrent files). The BitTorrent protocol does not rely on a central server, enhancing resilience as files can continue to circulate as long as at least one seed is available. To use torrents, a torrent client is needed, with recommended options for 2026 including qBittorrent, Transmission, and BiglyBT. The BitTorrent technology itself is legal, but legality depends on the content being shared. Legal uses include downloading Linux distributions, open-source software, and scientific datasets, while unlicensed movies and cracked software are illegal. In Russia, while torrent technology is not prohibited, downloading copyrighted content without permission is a violation. Risks of using torrents include exposure to viruses and malware, copyright infringement, fake distributions, and IP address exposure. To protect oneself, users should choose moderated trackers, avoid suspicious files, use antivirus software, and limit upload speeds. Common problems include slow speeds, connection issues, and disappearing files, which can often be resolved by checking settings or ensuring there are seeds available. Sharing files after downloading is not legally mandatory but is considered good etiquette in the torrent community.

Palworld studio says ‘gamers don’t want’ AI in their games: ‘It feels like everyone who is super gung-ho about it isn’t from the industry’

The gaming industry is experiencing an increase in AI-generated content, particularly on platforms like Steam. John Buckley from Pocketpair expressed concerns about the enthusiasm for AI, likening it to early cryptocurrency excitement, and highlighted the importance of human creativity in game development. He stated that Pocketpair will not publish games relying on generative AI. Additionally, Epic Games CEO Tim Sweeney raised concerns about undisclosed AI "placeholders" in major game releases, emphasizing the need for transparency in the industry.

How Cybersecurity Services Have Evolved Beyond Antivirus and Firewalls

Businesses traditionally relied on antivirus software and firewalls for cybersecurity, which were effective when threats were simpler and data was mostly stored on-site. However, the cybersecurity landscape has evolved, with cybercriminals employing advanced tactics that traditional methods cannot adequately address. Antivirus software is limited to detecting known threats, while modern malware can evade detection by altering its code or executing in memory. Firewalls also struggle when authorized users' credentials are compromised, allowing threats to infiltrate networks. Contemporary security strategies advocate for a multi-layered approach, incorporating tools like Endpoint Detection and Response (EDR), Multi-Factor Authentication (MFA), Zero Trust Architecture, Dark Web Monitoring, and Security Awareness Training. Compliance with regulatory standards is increasingly important, and cyber insurance providers now require businesses to demonstrate comprehensive security measures. Managed security providers are becoming essential for small and mid-sized businesses, offering expertise and resources to manage complex security tools and processes effectively. Organizations should assess their current security status and adopt a layered approach to address vulnerabilities, recognizing that traditional solutions alone are insufficient in today's threat landscape.

After years of forgetting Windows shortcuts, I finally found a method that makes them stick

On Windows 11, keyboard shortcuts enhance productivity, but many users are only aware of a few common ones like "Windows key + E" for File Explorer and "Ctrl + C" and "Ctrl + V" for copying and pasting. To help users discover more shortcuts, the Microsoft team behind PowerToys has released a revamped Shortcut Guide in version 0.100. This guide can be accessed through the GitHub page or the Microsoft Store and activated via PowerToys settings. Users can customize the guide's color theme, position, and exclude specific applications. The guide can be opened using the "Windows key + Shift + /" shortcut and provides organized shortcuts for Windows 11 and PowerToys. It also includes context-aware functionality, showing relevant shortcuts based on the active application. The development team has provided guidelines for developers to integrate their apps into the Shortcut Guide.

Windows Platform Security and the Race to Secure AI Agents

Microsoft has introduced the Microsoft Execution Containers (MXC) SDK to establish Windows as a reliable operating system for autonomous agents, focusing on containment, identity, and manageability. The MXC framework serves as a policy-driven execution layer for agents on Windows and Windows Subsystem for Linux (WSL), allowing developers to set access permissions using JSON or TypeScript. It employs process and session isolation for agent containment and identity. Future enhancements will include micro-VM support for high-risk tasks and integration with Windows 365 for cloud PC workloads. IT teams can manage MXC policies through Entra ID and Intune, while Defender and Purview provide protection and observability. The MXC framework is built on Microsoft's security initiatives, including Secure Boot and passwordless sign-in, allowing agents to inherit a secure foundation. However, early commentary expresses caution regarding MXC's perception as a comprehensive security solution, noting issues with overly permissive policies and the lack of outbound network filtering. Other platforms, such as Linux, are also enhancing security for agents with kernel-level isolation and secure environments like NVIDIA's OpenShell runtime. Various projects are focusing on agent sandboxes within Kubernetes, employing technologies like gVisor and Kata Containers for isolation. Overall, no singular dominant platform security model for AI agents has emerged, with Windows' MXC still considered nascent compared to existing solutions in Linux and Kubernetes ecosystems.
