Google Cloud has made technical contributions to PostgreSQL, focusing on advancements in logical replication, upgrade processes, and system stability. Key developments include the evolution of logical replication towards active-active configurations with automatic conflict detection to identify row-level conflicts during replication. This progress has sparked discussions about consistency models in database systems. Enhancements have also expanded logical replication to include sequences, reducing manual synchronization needs. Improvements to pg_upgrade have streamlined large object management and reduced upgrade times, while ensuring WAL data retention and schema constraint preservation. Bug fixes have addressed issues with index pages, extension loading, and WAL flush logic. Future features under development include a structured conflict log for replication and enhancements to parallel data export in pg_dump.

To install the Seekee app on a Windows PC, users can choose from several methods: 1. Using Bluestacks: This popular Android emulator simplifies the installation process. 2. Using MuMuPlayer: - Install MuMuPlayer on your Windows PC. - Import the XAPK file using the app installation feature. - Launch the app once installation is complete. 3. Manual Installation (if the XAPK does not open correctly): - Create a copy of the XAPK file. - Rename the extension from .xapk to .zip or use an archive tool to extract it. - Identify the package structure, looking for the Android/obb/com.example.app/ folder. - Install the main APK file in the emulator. - Copy the OBB data to the correct folder in the emulator's Android file system. - Launch the app after ensuring both the APK and OBB data are correctly positioned. XAPK installations may fail due to: - Incompatibility with the Android version. - Incomplete packages lacking OBB data or split APK components. - Mismatched package name and OBB folder. - Poorly repacked files. - Incompatible emulator profiles. A troubleshooting checklist includes: - Using BlueStacks with the Install APK option or drag-and-drop feature. - Exploring other emulators like MuMuPlayer. - Checking for app availability on Google Play within the emulator. - Ensuring OBB data is correctly placed. - Testing with different Android versions or emulator instances. - Re-downloading the file from a reliable source if suspected to be corrupted.

Microsoft is forming a team to enhance native Windows applications, coinciding with the launch of Speechify in the Microsoft Store. Speechify offers text-to-speech and speech-to-text functionalities, and has been noted for its effective dictation features. It is compatible with various chip architectures, including AMD, Intel, and Snapdragon X, and utilizes WinUI 3 for a native experience. Collaboration with Microsoft has optimized Speechify's functionality, allowing for integration across applications, real-time text input, and OCR-based text capture while ensuring local data security. The app can run in the cloud or locally, leveraging NPU or GPU acceleration. However, it has limitations, such as the inability to manually resize its window. Microsoft is encouraged to adopt Speechify's approach by supporting all chip architectures, ensuring availability in the Microsoft Store, and prioritizing native application development using WinUI 3.

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.

On April 3, 2026, Anthropic expanded Claude’s desktop control feature to Windows for Pro and Max subscribers, allowing users to operate applications, navigate web pages, and manage files on their PCs without prior configuration. The feature is in research preview and includes a Dispatch companion for task assignment from mobile devices. Claude uses a structured tool hierarchy for task execution, prioritizing connectors like Slack and Google Calendar, and engages in direct desktop control only when necessary. Users must opt in to activate the feature, which integrates with existing software without requiring API keys. The technology is partly derived from Anthropic’s acquisition of Vercept AI, which specializes in AI-driven computer control. Security concerns have arisen due to vulnerabilities demonstrated shortly after the launch, prompting Anthropic to implement safeguards while acknowledging the feature's potential errors. Users can stop Claude's operations, but the company admits it cannot disable the technology remotely once tasks have started. Competitors like Microsoft and Google are also exploring similar desktop-level AI automation capabilities.

Windows users have historically faced limitations in file management options, but the landscape has changed with the introduction of various alternatives. Microsoft has improved File Explorer in Windows 11, adding features like tabs and a streamlined interface. However, over 60% of global desktop users still experience issues such as slow folder loads and inconsistent menus. This has led some users to seek alternatives. Files is an alternative file manager that integrates well with Windows 11, featuring a clean design and core tab functionality that enhances usability. It allows for quicker navigation and improved organization, making everyday tasks smoother. OneCommander offers a dual-pane layout that changes how users manage files, making tasks like dragging files and comparing folders more efficient. Although it requires some adaptation, it is designed for users needing deep control over file management. After testing both, the user preferred Files for its seamless integration into their workflow, finding it more intuitive for quick tasks, while OneCommander is better suited for extensive file manipulation. The choice between the two depends on individual workflow preferences, with neither fully replacing File Explorer.

The Rust April update introduces several enhancements, including the new Water Wheel, a renewable energy source that generates up to 30 power when placed in a river. The update features a new craftable item, the Armored Ladder Hatch, which requires 60 Scrap, 35 High-Quality Metal, six Gears, and a Wooden Ladder. Adjustments to shield mechanics have been made, reducing the hitbox size when the shield is not actively held. A tech-tree unlock chaining feature allows players to unlock an entire research path at once if they have enough Scrap. A new radial menu for low-light solutions enables individual control of light sources. Fishing mechanics have been adjusted to prevent overfishing, with server admins able to modify this feature. Additional updates include new colored buttons, improved UI elements, and a transition to a new terrain rendering system for better CPU performance. The update coincides with an Easter Egg Hunt event running until April 16, featuring themed cosmetics.

An engineer from Amazon/AWS reported a significant performance regression in PostgreSQL when running on the nearly finalized Linux 7.0 kernel, with throughput dropping to about half of previous kernel versions. The regression, observed on a Graviton4 server, is attributed to increased time spent in a user-space spinlock due to changes in preemption modes in Linux 7.0. A patch to revert to PREEMPT_NONE as the default preemption model has been submitted but may not be adopted. Peter Zijlstra suggested that PostgreSQL should adapt to utilize the Restartable Sequences (RSEQ) time slice extension to mitigate the performance drop. If this adaptation is accepted, the responsibility for the performance decline may shift to PostgreSQL, potentially affecting users until the database is updated. The stable release of Linux 7.0 is expected in about two weeks, coinciding with the launch of Ubuntu 26.04 LTS.
