Microsoft is redesigning legacy dialog boxes in Windows 11, moving towards modern WinUI 3 interfaces. The company has begun implementing dark mode for some legacy dialogs, starting with file operation dialogs. A WinUI 3-based redesign of the Windows Run dialog is planned as an optional feature. March Rogers, Partner Director of Design at Microsoft, confirmed that a comprehensive redesign is underway, with the file copy dialog already completed and the common file dialog in progress. Users have expressed the need for more extensive updates to various legacy dialogs, and Microsoft is considering releasing these modern versions as optional features.

Windows 95 contains a block of code that checks if the user is playing SimCity and adjusts memory management to address a bug from the game's programming. This bug, a "use-after-free" error introduced by SimCity's developer Jon Ross, went unnoticed in Windows 3.x but caused crashes in Windows 95 due to its different memory management. Instead of asking Maxis to fix the bug, Microsoft engineers modified Windows 95 to mimic the older memory behavior, ensuring SimCity would run smoothly. This approach reflects Microsoft's broader strategy of maintaining compatibility with older software through various "shims," allowing legacy programs to function on modern systems.

Valorant's anti-cheat system, Vanguard, has been controversial due to its interference with DMA firmware devices, which are used to cheat in the game. Riot Games posted a message suggesting that Vanguard was making these devices unusable, leading to backlash from the gaming community. Riot clarified that Vanguard does not damage hardware or disable devices but prevents DMA cheat devices from functioning while IOMMU protections are enabled. Players not using DMA devices are not affected. The situation has sparked debate about the balance between anti-cheat measures and their impact on hardware.

Riot Games has clarified that its Vanguard anti-cheat system does not have the capability to damage players' PCs or disable their devices. The company stated that the "paperweights" referenced in a social media post were cheat devices that had been rendered ineffective by updates to the Vanguard system, which enforces security features on accounts using Direct Memory Access (DMA) cheating devices. While cheaters may experience hardware faults when using these cheats, this is a consequence of their actions, and only those using DMA-based cheats would encounter issues. Riot Games reassured players that their PCs would not be "bricked" due to Vanguard's operations.

PostgreSQL is widely used across various industries, supported by Microsoft through significant investments, including 345 commits to the latest release and a dedicated team of contributors. It is recognized for its ability to handle complex production challenges, such as transactional integrity and concurrency management. Microsoft operates PostgreSQL globally, informing upstream contributions based on real-world deployment experiences. The database is increasingly integrated into AI applications, with Azure Database for PostgreSQL and Azure HorizonDB focusing on AI functionalities. Microsoft offers multiple deployment models to accommodate different workload needs, including Azure Database for PostgreSQL for open-source workloads and Azure HorizonDB for cloud-native systems. Recent contributions from Microsoft include enhancements in asynchronous I/O, vacuum behavior, and query planning. Azure HorizonDB is designed for high-throughput, low-latency systems requiring horizontal scaling. Microsoft also invests in developer tools, such as a Visual Studio Code extension for PostgreSQL, and sponsors PostgreSQL conferences and user groups globally.

Researcher Andy Nguyen has developed a method to convert a PlayStation 5 into a Linux-based device, similar to a Steam Machine. This modification is only possible on launch-era PS5 consoles running system software version 4.5 or earlier, which dates back to December 2021. The process involves using a specific exploit to boot the operating system from a USB stick or the console's M.2 SSD expansion slot. The setup allows access to Ubuntu 26.04 LTS, utilizing 15GB of memory, all eight cores of the Zen 2 processor at 3.5 GHz, and all 36 compute units of the RDNA 2 GPU at 2.23 GHz. Users can control cooling by increasing fan speeds for overclocking. The output resolution is limited to 1080p, with performance tests showing comparable frame rates to the native PS5 environment for games like Black Myth Wukong, Crimson Desert, and Pragmata. However, issues such as stuttering and artifacting may occur due to the Proton compatibility layer and memory management challenges. This experiment suggests potential for emulation and playing PlayStation 3 games at enhanced settings.

Linux has been successfully implemented on the PlayStation 5, allowing users to run an open operating system on the console. This implementation, led by security researcher Andy Nguyen (TheFlow), utilizes an exploit for PS5 consoles with system software versions up to 4.5. Users can boot Linux from a USB or SSD, with Ubuntu 26.04 LTS providing around 15GB of usable memory. The PS5's hardware, including its Zen 2 processor and GPU, is fully accessible, with CPU speeds reaching up to 3.5GHz and GPU speeds up to 2.23GHz when boost mode is activated. However, running Linux on the PS5 presents challenges, such as sourcing a unit with the required firmware and limitations in resolution, as users cannot exceed 1080p. Performance tests showed that Linux can match the PS5's performance in some titles, but issues with memory management were noted, leading to stuttering and crashes in certain games. For example, reducing texture quality improved performance in games like Pragmata, while rendering issues were observed in Crimson Desert. The implementation allows for a unique gaming experience, but it also highlights the complexities and limitations of running Linux on a gaming console.
