Microsoft is giving Windows 11’s legacy UI dark mode instead of killing it, now in Hyper-V

Windows 11 is introducing dark mode support for various applications and features, including file-operation dialogs and the Hyper-V Manager tool. Recent updates have applied dark mode to several key dialogs within Hyper-V Manager, such as the New Virtual Machine, Export Virtual Machine, Import Virtual Machine, New Virtual Hard Disk, Edit Virtual Hard Disk, and the virtual machine settings page. The Virtual Switch Manager and Virtual SAN Manager also now support dark mode. These features are currently available in Windows Server and Windows 11 preview builds but are not yet in the production channel. Hyper-V Manager allows users to choose between light and dark themes, although switching requires a restart of the application. Microsoft plans to extend dark mode to more legacy areas of Windows and is working on rebuilding certain dialogs using WinUI, with dark mode support already appearing in preview builds for various components.

Android Malware Caught by Teaching AI to Read Apps as Pictures

A research team from Turkey, led by Erdal Başaran and Ömer Okucu of Ağrı İbrahim Çeçen University, along with Yusuf Alaca from Hitit University, has developed an innovative detection framework for Android malware that utilizes a visual approach. This framework transforms key features of Android applications into images, allowing a Vision Transformer to differentiate between benign software and malware. The researchers created two types of images from static and dynamic analysis features: a conventional 2D grayscale image and a QR code image. Separate Vision Transformer models were trained on each image type, and spatial pooling features were extracted from deeper layers to create a comprehensive representation of application behavior. To refine the fused feature vector, Recursive Feature Elimination (RFE) was employed, enhancing classification clarity and reducing computational load. The final classification utilized a majority-voting ensemble strategy, achieving a detection accuracy of 98.72 percent, surpassing standalone models. The study demonstrates that the multimodal system outperforms individual grayscale or QR code pathways. The dataset used is publicly available, promoting reproducibility. The framework's reliance on static and dynamic analysis features allows it to adapt to new threats, and the novel QR code representation offers distinctive visual signatures of malicious behavior. However, challenges remain regarding feature extraction quality and computational demands.

Query Plan Hints in PostgreSQL 19: A New Postgres Feature You Will Probably Never Need

PostgreSQL 19 features an advanced query planner that utilizes table statistics from pg_statistic, gathered during the ANALYZE process, to generate and evaluate potential query plans based on their costs. The planner assesses various configurations, especially in complex joins, to select the most efficient option. Instances of poor planning are treated as bugs and addressed promptly. To improve query performance, users are advised to refresh statistics with ANALYZE, use CREATE STATISTICS for column correlations, modify indexes, and adjust memory settings. In cases where the query cannot be altered, providing planner advice may be necessary, particularly when the planner misestimates the output of PL/pgSQL functions or other custom functions, leading to inefficient query execution.

Designing a Concurrent Donation Ledger With FastAPI and PostgreSQL

Every year, billions of dollars flow through online crowdfunding platforms, leading to donor concerns about the allocation of funds. Traditional crowdfunding applications lack transparency, often leaving funds in unverified balances without real-time auditability or guarantees against double-allocations. GoodCause, a social impact platform, aims to address this issue by creating a system that ensures financial integrity and atomic fund distribution. Its architecture is based on mobile-first delivery, atomic auditability, and strict data isolation, utilizing technologies such as React Native, FastAPI, and PostgreSQL. The platform incorporates a mobile client for cross-platform navigation, a backend API for domain-driven routing, a database with Row-Level Security, and a payment gateway for secure transactions. A significant engineering challenge is preventing race conditions and double-spending in concurrent donation scenarios.

The advent of first-person shooters introduced a wild frontier of unregulated video game level packs, and it ended in a lawsuit that changed copyright forever

In the 1990s, level packs emerged as a unique category of content for early first-person shooters like Duke Nukem 3D and Quake, sold as boxed products. Notable level packs included Duke Caribbean: Life's A Beach and Duke It Out in DC, which were well-received. Designer Wiederhold, recruited by Sunstorm Interactive after a LAN tournament, contributed to these packs alongside Robert Travis. The period was characterized by a lack of industry structure, allowing for creative exploration. However, some level packs, like Duke Assault, suffered from poor curation. The Nuke It series led to a legal battle over copyright infringement, with a 1998 court ruling favoring FormGen, establishing that video game mods are derivative works. This ruling curtailed unregulated FPS mission packs and clarified the distinction between official expansions and unofficial mods. Despite this, the mapping scene for iconic shooters continues to thrive today.

National Links: Stress Relief is a Minecraft Neighborhood

The Overhead Wire curates national and international news on urban landscapes and shares it with an engaged email list. They highlight stories from Greater Greater Washington, focusing on urban issues in the D.C. area. A research paper identifies five themes from interviews with apartment residents regarding their travel choices: self-selection, the built environment's impact on walking accessibility, transit service provision, subjective safety experiences, and the pragmatism of transport choices based on circumstances. A study reveals that 74% of Americans feel compelled to drive more than desired, with low-income drivers spending up to 40% of their income on transportation. The U.S. Department of Transportation has introduced a scoring bonus for transit projects based on birth and marriage rates, criticized for potentially benefiting certain demographics disproportionately. Cities are reimagining public safety by establishing independent departments for crisis response and violence prevention. The Talking Headways Podcast features Wendy Zhou discussing dynamic accessibility and the limitations of static maps. A quote reflects on the importance of long-term strategic thinking in societal infrastructure and technology adaptation.

How and why we built Managed PostgreSQL for AI workloads

The Nebius Managed PostgreSQL team developed a solution for AI workloads using CloudNativePG and Kubernetes, resulting in improved backup and restore times by transitioning from Barman to WAL-G, reducing a 1.5 TB backup duration from over a day to two hours. Since its launch in 2025, the service supports hundreds of production clusters and manages tens of tebibytes of data. Key features include high availability, point-in-time recovery, automated failover, compressed and encrypted backups, rapid restoration, connection pooling, and strict synchronous replication for zero data loss. Kubernetes and CloudNativePG were chosen for their advantages, including out-of-the-box features and open-source distribution. Each cloud project has a separate MK8s cluster for customer isolation and security. Persistent data is stored on fault-tolerant SSD drives, enabling swift instance migration during failures. Regular physical backups are archived, allowing restoration within a seven-day window with a single click. The transition from Barman to WAL-G addressed slow backup and restoration times and resource control limitations. With WAL-G, backups and restorations for a 1.5 TB cluster improved to two hours and one hour, respectively. PgBouncer was implemented to manage database connections effectively, reducing connection storms during peak AI workload traffic. Two vector search extensions, pgvector and pgvectorscale, are available to cater to different memory and dataset needs. Benchmarking showed that Nebius performs competitively with AWS at a lower cost. The infrastructure integrates cloud engineering principles with specialized expertise to meet AI workload demands.
