Linux 7.0 Cuts PostgreSQL Performance in Half

An AWS engineer reported a significant drop in PostgreSQL throughput on Linux 7.0, with performance reduced to approximately half of its previous capability. Benchmark tests showed that the removal of the PREEMPT_NONE scheduling option was the main cause of this regression. On a 96-vCPU Graviton4 instance, throughput measured at just 0.51x compared to earlier kernel versions. Salvatore Dipietro from Amazon/AWS conducted benchmarking analysis of PostgreSQL 17, revealing that Linux 7.0 delivered only 0.51x the throughput of its predecessors. The root cause was traced to kernel commit 7dadeaa6e851, which eliminated PREEMPT_NONE as the default option, leading to increased contention due to the new PREEMPT_LAZY model. Profiling data indicated that 55% of CPU time is consumed by spinning in PostgreSQL’s spinlock, causing significant performance degradation. When a revert patch was applied, throughput rebounded to 1.94x the baseline. The decision to restrict preemption modes in Linux 7.0 aimed to address issues within the kernel's scheduling model. Dipietro proposed a patch to restore PREEMPT_NONE, but kernel developers suggested PostgreSQL adopt the rseq time slice extension instead. Database operators running PostgreSQL on Linux face potential performance reductions with the upgrade to Linux 7.0.

Native Apps? It’s a Trap! ⭐️

Microsoft's Copilot+ launch event in May 2024 introduced a feature called Recall, which sparked privacy concerns among enthusiasts. Pavan Duluri, head of Windows, indicated a focus on addressing Windows 11's "pain points" in 2026, but expectations among fans exceeded his promises. The introduction of AI features, including Copilot, received mixed reactions, with some users fixating on the removal of elements like the Copilot icon rather than overall functionality. There is a divide between passionate enthusiasts and the broader user base, complicating Duluri's task of balancing user needs with corporate demands for new AI features. Rudy Huyn, a principal lead architect at Microsoft, promised to replace web-based inbox apps with "100 percent native" applications, a claim viewed skeptically due to the complexities involved. While enhancing web-based experiences is feasible, many significant web apps are designed to remain as such. The challenges facing Windows include broader corporate strategies and user dissatisfaction, with concerns about perceived declines in quality. Improvements to features like the Start menu and File Explorer may not satisfy ongoing complaints from enthusiasts.

‘NoVoice’ Android malware on Google Play infected 2.3 million devices

A new Android malware called NoVoice has been found in over 50 applications on Google Play, with more than 2.3 million downloads. The malware targets older Android versions, specifically those patched between 2016 and 2021, and attempts to gain root access by exploiting vulnerabilities. It conceals malicious components within the com.facebook.utils package and uses steganography to hide an encrypted payload within a PNG image file. NoVoice avoids infecting devices in certain regions and has checks to detect emulators and VPNs. Once activated, the malware contacts its command-and-control server to gather device information and polls it every 60 seconds for tailored exploits aimed at rooting the device. It can exploit 22 vulnerabilities, including kernel bugs, and establishes persistence by replacing key system libraries and installing recovery scripts. The malware injects code into applications, particularly targeting WhatsApp to extract sensitive data for session replication, which is then exfiltrated to the C2 server. The malicious apps containing NoVoice have been removed from Google Play, but users who installed them should consider their devices compromised. Upgrading to devices with later security patches is recommended to mitigate the threat.

Fastfetch 2.61 System Information Tool Drops Windows 7 and 8 Support

Fastfetch version 2.61 has been released, discontinuing support for Windows 7 and 8, with Windows 8.1 as the oldest supported version. The GPU module on Windows now uses DXCore for improved detection accuracy, available only on Windows 10 and later. In the Windows Subsystem for Linux (WSL), the GPU module has been optimized for speed but may have reduced accuracy due to the removal of directx-headers. On Linux, Fastfetch has transitioned to a pure C implementation, enhancing performance and simplifying the build process. New features include a brightness option for color display, detection of Bluetooth keyboards on Linux, display of empty memory slots, support for GlazeWM detection, identification of marketing product names on Asahi Linux, and recognition of M5-based Mac models on macOS. Improvements in hardware detection and system reporting have been made across all platforms, with enhanced SMBIOS data handling and reliability for Intel-based Macs. Stability improvements for terminating child processes on Windows have also been implemented. Critical fixes address missing memory device reporting, CPU cache deduplication issues, accurate window manager version reporting for niri, SSID decoding problems, and a Windows-specific issue affecting the command prompt code page.

What Is Conhost.exe?

Conhost.exe, or Console Window Host, is a legitimate Windows system process responsible for managing the display and behavior of console windows such as Command Prompt and PowerShell. It facilitates text rendering and manages input/output interactions with the graphical user interface. Each time a console application is launched, a new instance of conhost.exe is created, and multiple instances can appear in Task Manager based on active console applications. To verify the authenticity of conhost.exe, it should run from C:WindowsSystem32 or C:WindowsSysWOW64, have a valid Microsoft Windows Publisher digital signature, and not make outbound network connections. High CPU usage or unusual behavior may indicate malware masquerading as conhost.exe. Troubleshooting steps for issues related to conhost.exe include running a malware scan, checking for Windows updates, updating device drivers, and using the System File Checker. Disabling conhost.exe is not advisable as it is essential for the functioning of console applications.
