Database performance analysis using pg_profile and pgpro_pwr

pgpro_pwr is a database workload monitoring tool for database administrators (DBAs) to identify resource-demanding operations. It was launched in 2017 as pg_profile by Andrey Zubkov, who moved from being a DBA to an engineer at Postgres Professional. pg_profile is compatible with open-source PostgreSQL and has been integrated into PostgreSQL 17 as of 2024, while pgpro_pwr offers advanced statistical insights and is included in Postgres Pro releases. Both tools monitor database workload metrics through continuously incrementing counters, capturing values at intervals and archiving differences. They do not provide alerting capabilities but are useful for assessing system stability, analyzing load testing outcomes, and identifying system-intensive activities. The tools consist of repository tables, data collection functions, reporting functions, and service tables. To use them, one must install the extension, configure roles, and set up parameters. Reports can be generated for workload statistics over time and comparisons between different time intervals. Examples of report types include wait event statistics and advanced vacuum statistics. Future plans include submitting a patch to introduce vacuum statistics to vanilla PostgreSQL.

Microsoft Windows File Explorer Vulnerability Let Attackers Perform Network Spoofing

A vulnerability identified as CVE-2025-24071 has been discovered in Windows File Explorer, allowing attackers to extract NTLM hashed passwords with minimal user interaction. This high-severity flaw, termed “NTLM Hash Leak via RAR/ZIP Extraction,” exploits Windows Explorer’s automatic file processing when a specially crafted .library-ms file is extracted from a compressed archive. The file contains a malicious SMB path that triggers an NTLM authentication handshake, leaking the victim’s NTLMv2 hash. Microsoft addressed this issue in its March 2025 updates. A proof-of-concept exploit was published by researcher 0x6rss, and evidence suggests the vulnerability may have been exploited in the wild prior to its disclosure. Users are advised to apply security updates and implement protections against NTLM relay attacks.

Windows Defender misidentifies key driver, disrupting popular PC monitoring tools

PC gamers experienced false alarms from Windows Defender regarding the kernel-level driver WinRing0, which is essential for hardware monitoring applications. This misidentification caused issues such as fan control applications malfunctioning after being quarantined. WinRing0 allows applications to interact with hardware components, and its use is widespread among developers. Microsoft flagged WinRing0, complicating matters for developers due to the requirement for digital signatures on drivers, which can be costly for open-source projects. Some developers, like SignalRGB, are creating proprietary drivers as alternatives, though this requires significant resources. Microsoft is reviewing its detection logic to reduce false positives, while iBuyPower plans to provide a signed version of WinRing0 to aid developers. Users may need to update applications or adjust Windows Defender settings to maintain functionality, as Razer and SteelSeries have moved away from using WinRing0 in their software.

5 cool things to do with virtual machines on Windows 11

Windows 11 simplifies the setup of virtual machines (VMs) using Hyper-V or Oracle's VirtualBox, allowing users to quickly establish VMs for various purposes. Users can run legacy applications and games that struggle on modern systems by utilizing older operating systems like Windows XP or Windows 7, or using DOSBox for very old games. VMs enable users to operate multiple operating systems simultaneously, catering to different needs such as programming or graphic design. They can also help maintain privacy against workplace monitoring by isolating personal activities from employer-mandated tracking software. Additionally, VMs allow users to safely explore potentially harmful software for cybersecurity purposes, although caution is advised due to the risk of sophisticated malware escaping the VM. Backing up an entire operating system within a VM is straightforward, involving the management of files like virtual disk images and configuration files, but users should be aware of legal considerations regarding sharing or duplicating VMs.

Scaling Your Startup’s Data Infrastructure with PostgreSQL

Robust data infrastructure is essential for startup development as data requirements grow. PostgreSQL is a leading open-source relational database known for its scalability and comprehensive features. A Timescale survey indicates that 51.2% of users increased their PostgreSQL usage in the past year. PostgreSQL employs a multi-version concurrency control (MVCC) system and write-ahead logging (WAL) for data integrity and recovery. Vertical scaling enhances hardware capabilities, while horizontal scaling distributes loads across multiple servers through replication, partitioning, and sharding. High availability is achieved via replication and failover systems, with load balancing optimizing resource usage. Performance optimization techniques include regular indexing, query optimization, and routine maintenance. Monitoring tools like pgAdmin and Prometheus are crucial for maintaining database health and performance.
