ReactOS 0.4.16 serves ’90s Windows nostalgia with fewer bugs

ReactOS has released version 0.4.16, which includes a unified boot and live CD image, a graphical installer, and significant upgrades to video, audio, networking, and storage stacks. The update addresses compatibility issues with legacy software, particularly with video drivers and the kernel’s system page table entries, improving stability. A new HD audio bus driver has replaced an older implementation, and the UniATA driver has been replaced with a new ATA driver for better compatibility and boot times. Networking capabilities have improved with expanded support for adapters and asynchronous connections. A headless Server Core installation type has been introduced, and compatibility restrictions with Windows Server 2003 have been lifted. ReactOS remains in an alpha state, and version 0.4.16 is available for download.

Connecting My LangGraph AI Agent to Postgres

A stateful LangGraph agent was developed to streamline a 15-minute booking process, featuring a user-friendly Streamlit UI and a backend powered by a Postgres database. The agent responds to customer queries, calculates service pricing, manages service acceptance, suggests time slots, and confirms appointment details. It operates in two modes: in-memory for rapid testing and Postgres for persistent storage. Testing can be done locally using Docker, which simulates a Postgres environment, or with a hosted Postgres instance. The project includes a docker-compose.yml file to initiate a PostgreSQL 16 container, allowing the application to connect to the database. Data persistence is ensured through Docker volumes, and the application can be run with specific commands after setting up the environment variables. The system has been tested successfully, demonstrating its ability to manage bookings and maintain data integrity across sessions. Future enhancements are planned to improve the booking workflow and integrate additional communication channels.

Autoscaling Lakebase Postgres

Choosing a database instance size without prior knowledge of the workload can lead to inefficiencies and excessive compute usage. Lakebase Postgres addresses this with an autoscaling feature that eliminates manual sizing, utilizing in-place VM resizing and a monitoring algorithm for CPU, memory, and working set size. Lakebase Postgres separates compute and storage layers, allowing independent resizing of compute nodes without affecting the database. The autoscaling algorithm relies on three signals: CPU load (cpuGoalCU), memory use (memGoalCU), and compute-cache working set size (lfcGoalCU). The CPU load is monitored every five seconds, aiming to maintain it at or below 90% capacity. Memory usage is tracked at two frequencies: overall memory every five seconds and Postgres-specific memory every 100 milliseconds, with a goal to keep usage below 75% of allocated RAM. The compute cache evaluates active data access efficiency, adjusting size based on workload. The working set is estimated using a modified HyperLogLog algorithm that records timestamps for page accesses, allowing for distinct page estimates over various time frames. The algorithm projects future working-set growth to allocate sufficient cache while capping it at 75% of RAM. Resizing the compute involves four components: the autoscaler-agent, vm-monitor, Kubernetes scheduler, and NeonVM. Scaling up occurs when any of the three goals indicate a need for more resources, while scaling down includes verification to ensure sufficient memory remains for operations. Timely adjustments in both directions are prioritized to minimize costs.

3 tasks that are still easier on Linux than Windows

Linux users benefit from a streamlined software update process through package managers like APT, DNF, and Pacman, allowing all applications to be updated with a single command. In contrast, Windows requires multiple update mechanisms for the operating system and third-party software, often necessitating manual checks. Most drivers in Linux are built into the kernel, enabling automatic recognition and configuration of new hardware, while Windows typically requires users to download drivers from manufacturers' websites. Linux provides clearer system logs for troubleshooting, making it easier to diagnose issues, whereas Windows error messages can be vague and less informative. Overall, Linux offers advantages in software updates, driver management, and troubleshooting compared to Windows.
The AI memory crunch has reached the apps on your phone

The AI memory crunch has reached the apps on your phone

Google will implement new memory usage regulations for Android applications starting in February 2027, due to a global RAM shortage. Apps exceeding the set memory limits may be throttled, terminated, or face reduced visibility on the Play Store. The memory thresholds vary based on device specifications, with specific limits for foreground, background, and bitmap memory usage. Non-compliance will result in penalties affecting app distribution and visibility. The memory crisis is attributed to increased demand from the AI data center industry, leading to rising RAM costs. The new limits will first apply to Pixel devices with Android 17, and other manufacturers are expected to follow. Additionally, by April 2027, all apps on the Play Store must support zero-tap credential restoration for users transitioning to new devices.

New JK Terror Tactic: Pornography Apps, Tor Network Used For Secret Messaging

Security agencies in India have observed a shift in the tactics of terrorist groups, which are now using pornography websites and niche encrypted applications for communication instead of traditional social media. These groups, often collaborating with Pakistan's ISI, utilize platforms with real-time chat tools disguised as dating services to send instructions to recruits in Jammu and Kashmir. Security agencies are monitoring various digital tools, including Tor-based applications like Coatex and Conion, which obscure user identities. Some privacy-focused platforms do not require phone numbers for registration, complicating tracking efforts. Despite bans on certain pornography applications in India, they are still accessed illegally via VPNs, which mask users' IP addresses. The use of the Tor network presents additional tracking challenges, as it obscures data origins and destinations. Security agencies are adapting their surveillance methods in response to these developments, which include the use of virtual SIM cards in terrorist activities, as highlighted during investigations into the 2019 Pulwama attack.

Windows 11 is accused of using AI to slow your PC, but it’s not what you think

Windows 11's privacy settings have caused confusion among users regarding the Text and image generation feature, leading to misconceptions that AI processes are actively running and draining system resources. Screenshots showing "zero" requests in the Recent activity section indicate that these features are not consuming RAM. The privacy page is intended to inform users about which applications can use on-device generative AI models, but it does not imply that these applications are currently using AI. The processing occurs on a specialized chip, ensuring that it does not burden the CPU, GPU, or standard RAM. Users can disable the feature by navigating to Settings > Privacy & security > Text and image generation. The terminology used in the operating system has contributed to misunderstandings, and the setting was enabled by default, which has led to skepticism among users due to Microsoft's history of implementing features without clear communication.
