Microsoft explains why restarting Windows can shut it down more completely than actually shutting it down

The Fast Startup feature in Windows, enabled by default, allows the kernel session to remain hibernated during shutdown, which results in quicker boot times by restoring a saved state. In contrast, selecting Restart clears the kernel session entirely, performing a complete boot of Windows. The process of shutting down with Fast Startup involves closing applications, logging off, keeping the kernel loaded in memory, saving the kernel and drivers to hiberfil.sys, and powering off, while Restart closes applications, logs off, ends the kernel session, and reboots immediately without saving a kernel snapshot. Fast Startup can lead to persistent issues from previous sessions, making Restart a better option for troubleshooting. To perform a full shutdown bypassing Fast Startup, users can execute the command "shutdown /s /t 0." Microsoft advises against permanently disabling Fast Startup, as it enhances shutdown-to-boot transitions.

Arm’s new CPU cores and GPUs for Android chips promise ‘desktop-class’ games, more AI power

Arm has introduced new C2-Ultra and C2-Pro CPU cores with a 15% increase in single-thread performance and 12% faster app launches. The CPUs feature local AI integration, eliminating the need for a separate NPU or TPU. The Mali G2-Ultra NX GPU offers "desktop-class" performance with AI-native graphics, delivering a 14% performance boost and supporting Unreal Engine 5 "MegaLights." These advancements will debut in Xiaomi's 18 Fold phone initially.

How to Fix Minecraft Lag and Stuttering on PC and Mac in 2026

Experiencing a freeze in Minecraft Java Edition can be frustrating due to the game's demands on computer performance, which can lead to lag spikes, stuttering, and low FPS. Performance issues can often be resolved without new hardware by optimizing settings on Windows and macOS. To address lag, identify the type of lag and adjust settings one at a time, starting with visuals and add-ons, then moving to memory, Java, drivers, and multiplayer servers. Quick fixes include closing background apps, restarting Minecraft, testing in a single-player world, disabling shaders, using default resources, and lowering render distance. Different types of lag include low FPS, stuttering from world loading, network or multiplayer server lag, and performance drops after enabling visual add-ons. To diagnose lag, symptoms should be matched with potential causes and fixes, such as adjusting video settings or checking server performance. Common issues include low FPS, stuttering while exploring, FPS drops when shaders are enabled, resource pack hitching, and problems with memory allocation or incompatible Java versions. Each issue has specific symptoms, causes, and recommended fixes, such as adjusting render distance, disabling shaders, or ensuring the correct Java version is used. Platform-specific fixes for macOS and Windows involve updating drivers, managing graphics settings, and ensuring proper memory allocation. Configuration mistakes can hinder performance improvements, and hardware limitations may also play a role in lag. For ongoing issues, gathering relevant logs and system details is essential for seeking help, and preventative tips include maintaining a clean test profile, gradually adding mods, and matching versions carefully.

How Five PostgreSQL Optimizations Sped Up Our Dashboard

The dashboard operates on a Django monolith with PostgreSQL and is transitioning to ClickHouse for denormalization. The initial p50 metric was 0.7 seconds, but the p95 was 8 seconds, which was reduced to 1 second. Observability tools were established to monitor performance, and slow HTTP requests were identified using OpenTelemetry traces. Optimization techniques included late joining, asynchronous counting, creating a PostgreSQL replica for read operations, and improving full-text search. Denormalization was explored to enhance filtering performance by creating composite indexes. The production stack was upgraded to PostgreSQL 18, which provided incremental performance improvements. The final p95 value achieved was 1 second, below the target of 3 seconds.

Azure HorizonDB Enters Public Preview: Web IQ Already Powers Copilot and ChatGPT

Microsoft announced the public preview of Azure HorizonDB, a fully managed PostgreSQL-compatible database designed for agentic AI workloads, during Microsoft Build 2026 in San Francisco. HorizonDB features a "database-as-logs" architecture, allowing for sub-millisecond multi-zone commit latency and independent scaling of compute and storage. It incorporates a Rust-based storage engine, native DiskANN vector search, and in-database AI model invocation. Additionally, Microsoft launched Web IQ, a web-grounding API layer integrated into Microsoft Copilot and OpenAI's ChatGPT, which provides passage-level structured evidence objects rather than full documents. Web IQ is model-agnostic and aims to enhance information density and reduce costs. Both services are currently in limited availability, with HorizonDB open for preview signups across five Azure regions.

Accelerating developer productivity in the agentic AI era with Amazon Aurora PostgreSQL

Pravin, who leads engineering for Amazon Aurora, shared an anecdote about his son and friends using AI-assisted coding tools to develop an app without needing to worry about database setup. Elizabeth from AWS Databases noted that teams can now deliver projects in days instead of months, with a broader demographic of builders, including analysts and designers. Engineers in Pravin's organization are creating agents that significantly reduce on-call work, and product managers are drafting documents more efficiently. Aurora aims to address the challenges posed by rapid development changes by adhering to three core principles: meeting developers where they work, absorbing workload variability, and growing with applications. Aurora PostgreSQL is integrated into AI coding tools, allowing developers to set up databases quickly. It features a serverless model that automatically scales to meet fluctuating demands, accommodating workloads from small projects to large-scale applications. The database supports existing tools and frameworks, ensuring compatibility and easing migration challenges. Examples of successful transitions to Aurora PostgreSQL include SurveySparrow, which achieved cost savings and improved query latency, and Netflix, which reported significant performance improvements. Aurora's flexibility allows developers to use both serverless and provisioned instances within the same cluster, optimizing operations without data migration. It also provides options for tuning performance and maintaining an up-to-date database with minimal disruption. Aurora Global Database enables applications to expand across regions without overhauling the data layer, supporting cross-region disaster recovery and low-latency reads. Companies like S&P Dow Jones Indices and DraftKings have successfully leveraged Aurora to support their growth and operational needs. Aurora PostgreSQL is designed to empower developers, facilitating innovation across various project scales.

Microsoft’s new Windows 11 Run dialog is faster than the Windows 95-era version it’s replacing

Microsoft is developing a modernized version of the Run dialog for Windows 11, featuring a streamlined design created using C# and WinUI 3. The new Run dialog has a median "time-to-show" of 94 milliseconds, which is an improvement over the old dialog's 103 milliseconds. This new version is designed to be more functional and user-friendly, allowing users to quickly access their home directory and supporting dark mode. The modern Run dialog is currently being rolled out as an opt-in feature for Insiders in the Experimental Channel.

Nvidia graphics research just made a 2-3x gain in performance, and this time it didn’t use AI

Nvidia has released a research paper that indicates potential graphics performance improvements of 2-3 times in certain scenarios, utilizing techniques like reciprocal neighbor selection and duplication maps, without heavily relying on artificial intelligence. The research focuses on path tracing, a rendering technique that is currently only feasible on advanced graphics cards. Nvidia's recent advancements include reservoir-based spatiotemporal importance resamplers (ReSTIRs), which could achieve up to a 65x performance improvement over existing methods. The new paper revisits this algorithm, offering an additional 2x-3x performance boost and enhancing image quality. The research suggests that path-traced modes in video games could experience significant performance enhancements, although it remains unclear if these improvements can be implemented via a simple driver update or if new hardware will be required.
