Google is optimizing Android’s core to make your phone feel faster

Google is implementing Automatic Feedback-Directed Optimization (AutoFDO) within the Android kernel to enhance the performance of Android devices. The Android kernel accounts for approximately 40% of CPU time, and improvements in this area can significantly boost overall performance. AutoFDO uses real-world data to optimize code based on actual smartphone usage patterns, rather than general assumptions. Tests conducted on Pixel phones analyzed kernel usage with the top 100 popular Android applications, identifying frequently accessed code segments for targeted optimization. This approach is expected to lead to faster app launches, smoother transitions, and improved battery life. The kernel AutoFDO is currently being deployed in the android16-6.12 and android15-6.6 branches, with plans to extend optimizations to additional kernel components and hardware drivers.

Windows 11 is making big changes to printing, because printers are awful

Microsoft is transitioning to a universal printer driver system to address issues related to legacy printer drivers in Windows. Starting with Windows 10 version 21H2, a universal printer driver compatible with Mopria standards has been integrated and is being enhanced through updates. A phased approach to legacy printer drivers will begin in January 2026, when Windows Update will stop allowing new legacy drivers for Windows 11 and Windows Server 2005. Existing drivers for older printers will continue to function. In July 2026, Windows 11 will prioritize the universal driver over legacy drivers, and by July 2027, updates for legacy drivers will be limited to security fixes. There is no set timeline for the complete discontinuation of old printers and their drivers.

Windows 98 On A 2020 ThinkPad P14s Gen 1 Laptop

The x86 architecture allows users to run operating systems from the 1990s on modern hardware. Yeo Kheng Meng successfully booted Windows 98 SE on a 2020 ThinkPad P12s Gen 1 alongside Windows 11 and Linux from a single NVMe drive. He previously ran MS-DOS 6.22 on a 2020 ThinkPad X13. The main challenges included UEFI complexities and the need for compatible hardware drivers. Both ThinkPad models support UEFI-CSM mode. To address the lack of xHCI support in Windows 98, Yeo used a USB 2.0 expansion card through a Thunderbolt dock. The installation involved disabling Secure Boot, enabling UEFI-CSM, activating Thunderbolt BIOS assist mode, and turning off Kernel DMA protection. Yeo used the CREGFIX DOS driver for stability and applied patches from Rudolph Loew to overcome Windows 98's RAM limitation of 512 MB. Users must rely on basic VESA support and the SoftGPU driver for graphics acceleration due to the absence of updated drivers from Intel and NVIDIA. Disk access is routed through the BIOS, leading to suboptimal performance. Yeo configured the BIOS to support the S3 power state to address ACPI support issues. UEFI-CSM is often overlooked in newer systems, complicating the installation of Windows 7 and contributing to divides in the x86 ecosystem.
