I tested Microsoft PC Manager’s RAM-freeing tool and learned why high memory usage isn’t always a problem

Users of Windows 11 often report high RAM usage, with figures reaching 70-90 percent, leading to concerns about system performance and the need for memory upgrades. Microsoft has introduced the PC Manager application with a "Boost" option to help free up memory. High memory usage can be normal when Windows 11 caches files, but excessive consumption by poorly optimized applications may indicate a resource issue. The impact of memory usage varies by system; for example, 90 percent usage may be acceptable on a system with 96GB of RAM, while it could be problematic on an 8GB system. Context matters, as high memory usage on high-end machines often represents normal caching, whereas it may signal struggles on lower-end systems. The PC Manager's Boost feature can be useful before resource-intensive tasks but may reinforce misconceptions about high memory usage being inherently negative. Ultimately, performance issues, rather than memory percentage alone, should guide decisions about upgrading RAM.

Announcing Lakebase Search: agent-native retrieval built into Lakebase Postgres

Lakebase Search is a hybrid vector and full-text retrieval system integrated into Lakebase, now in beta on AWS and Azure. It utilizes two Postgres extensions: lakebase_vector and lakebase_text, allowing agents to operate on a single data backend. Agents manage four times more databases than human users and require real-time access to indexed data. The system features a tiered architecture that stores cold data in cost-effective object storage while keeping active data in local NVMe, significantly reducing costs. The lakebase_vector extension offers 32x compression for vectors, allowing a billion vectors to fit into under 10GB of RAM. The lakebase_text extension provides BM25 relevance ranking without high RAM usage. Benchmarking shows that Lakebase Search can efficiently handle large-scale workloads, achieving high recall and low latency with reduced resource requirements compared to traditional architectures. The system allows for continuous search experimentation and dedicated retrieval engines for each agent, enhancing operational efficiency and scalability.

Android Auto Quietly Added Support For A Surprisingly Useful New App

Adobe Acrobat Reader has been integrated into Android Auto with the v26.5.0.45958 update. Full access to its features requires a subscription, but non-subscribers can use limited free features, including accessing scanned PDFs in Liquid Mode, annotating documents, signing PDFs, and connecting to Google Drive. Visual functions are disabled on the car's screen for safety, but a "Read Aloud" text-to-speech engine is available for free users. Paid subscribers can access high-quality voices, Adobe's AI assistant for file management, a complete mobile editing suite, optical character recognition (OCR), and additional tools, although advanced features are currently not accessible through the dashboard.

PostgreSQL Dump and Restore: The Complete pg_dump Guide

pg_dump is a utility for exporting a PostgreSQL database into a file, which can be restored on the same or different servers. It exports a single database's tables, views, sequences, functions, indexes, triggers, and in-database grants but does not include roles, tablespaces, or server-level configurations. To capture global objects, pg_dumpall --globals-only should be executed prior to the per-database dump. pg_dump requires CONNECT and SELECT privileges on all tables and sequences within the target database, and a dedicated backup role is sufficient for single-database dumps, while superuser access is needed for global objects. pg_dump supports various output formats: plain SQL (.sql), custom binary (.dump), directory of files, and tar archive (.tar), each with different capabilities for restoration and compression. The custom format allows for selective and parallel restoration. For non-interactive use, credentials can be stored in a .pgpass file or passed via the PGPASSWORD environment variable. Restoration methods depend on the dump format: psql is used for plain SQL files, while pg_restore is used for custom and directory formats. The restoration process requires the target database to be created beforehand. Version mismatches between pg_dump and pg_restore can lead to failures, so it's essential to ensure that the binaries are version-matched. In Docker, pg_dump and pg_restore can be executed within containers, but care must be taken to manage credentials and ensure version compatibility. Exit codes from pg_dump should be checked to confirm successful operations.

KRVR Supports Apple Vision Pro’s Foveated Streaming For SteamVR Games

KRVR is a visionOS application that allows users to play SteamVR games on the Apple Vision Pro using foveated streaming technology. It is a closed-source app that combines features from free, open-source alternatives like ALVR and Clear XR. KRVR supports a wide range of SteamVR titles, including those not using OpenXR, and integrates Nvidia's CloudXR SDK for enhanced visual fidelity. The app includes features such as passthrough cutouts for physical space integration and PC desktop access for multitasking during gameplay. It is compatible with Sony's PlayStation VR2 Sense controllers and other input devices but requires Nvidia's Ada or Blackwell GPU architectures, limiting support to RTX 40-series and 50-series graphics cards. KRVR is available for download on the App Store, with a Windows PC server application on GitHub.

Half of all PC gamers now have GPUs with more than 8GB of VRAM

Approximately 49.95% of PC gamers are using graphics cards with more than 8GB of VRAM, with 23.51% using 16GB, 13.45% using 12GB, and 26.76% using 8GB. Additionally, 6.19% of gamers have GPUs with 24GB or more VRAM. The demand for higher VRAM is driven by the need for better image fidelity in gaming, particularly with high-quality textures and effects like ray tracing. The growth of GPUs with 16GB of VRAM is notable, led by models such as the GeForce RTX 5060 Ti 16GB and Radeon RX 9060 XT 16GB. Despite this trend, the current memory crisis may keep 8GB cards relevant for another generation.

LofyStealer Targets Minecraft Players via Node.js Loader and Browser Injection

Minecraft players are being targeted by a deceptive hacking tool called “Slinky,” which is actually an infostealer known as LofyStealer linked to the Brazilian cybercrime group LofyGang. The malware uses a Node.js-based loader and a C++ payload to extract sensitive browser data, disguising itself as a Minecraft hack. It primarily targets younger players who may unknowingly execute it. The malware operates through a two-stage architecture, with a 53.5 MB loader binary that injects a smaller 1.4 MB payload into browser processes, bypassing detection methods. It collects sensitive information such as cookies, passwords, and credit card details, compressing and encoding the data for exfiltration. The command-and-control (C2) infrastructure is hosted in Brazil, and the malware's design reflects advanced compilation techniques. The campaign is attributed to LofyGang, which has evolved into a more professional entity, posing severe risks to players who download cheats and cracked tools. Indicators of compromise include a specific C2 IP address and associated endpoints.

I investigated Windows 11’s massive 5GB monthly .msu updates. AI is only part of the problem.

Windows 11 updates have significantly increased in size, with monthly cumulative updates often exceeding 4GB and some approaching 5GB. One update can expand to nearly 9GB when extracted. Microsoft has shifted to delivering Latest Cumulative Updates (LCUs), which include all previous fixes, leading to larger update sizes over time. The introduction of Checkpoint Cumulative Updates aims to reduce this growth by establishing periodic baselines, but the effectiveness has been mixed. The May 2025 cumulative update saw a size increase from approximately 6.5GB to nearly 9GB, with new MSIX files related to semantic search and on-device AI contributing to this growth. Windows Update uses applicability logic to minimize download sizes for users, but enterprises must download full packages, resulting in increased storage costs. The average yearly storage cost for enterprises rose from about 11 GB in 2024 to 52 GB by 2026. Users can check their actual download sizes through the Windows Update settings and Event Viewer logs.
