Commodore Callback 8020 Retro Flip Phone Runs Android Apps

The Commodore Callback 8020 is a Sailfish OS flip phone designed to block browsers and social media, while retaining essential features like maps, messaging, music, and calls. It operates on Sailfish OS and can run over 99% of Android apps through a sandboxed Android AppSupport layer. The device lacks Google Play Services and the Play Store but comes preloaded with WhatsApp and supports various applications such as Signal, Telegram, and mapping services. It blocks web browsers and major social media applications at the system level, and email and work-related apps are excluded from the app store. The Callback 8020 features a clamshell design, T9-style texting, a 48MP rear camera, FM radio, and comes in multiple retro-inspired finishes. Preorders will start on June 30 at a price of 9.99, with shipping expected to begin in winter.

Microsoft once used its own brand of ‘Lego’ to optimize Windows

Former Microsoft engineer Dave Plummer reflected on software performance challenges during the '90s, specifically the limitations of machines with 12 MB of RAM. He discussed the Basic Block Tool (BBT), which optimized software binaries by reorganizing their structures to enhance execution speed. A typical binary contained around 10 MB of code, but only about 300 KB was necessary for startup. If this essential code was scattered, it led to performance degradation due to excessive page access. BBT defragmented binaries, grouping related code to streamline access and improve user experience, particularly for large products like Windows and Office. Modern tools like BOLT and HP's Dynamo continue to optimize binary layouts and runtime code, but Plummer cautioned about the risks of manipulating binaries. He noted that while computational power has increased, modern software faces similar performance challenges, with larger binaries and complex dependency graphs. He emphasized the importance of locality in software design, advising to keep hot data and code together to enhance performance.

NVIDIA’s RTX Spark launch is huge, but Qualcomm and Microsoft built the Windows ARM foundation

Qualcomm announced the Snapdragon X Elite in 2023, an ARM-based processor that outperformed traditional x86 processors. The Snapdragon X Series featured a custom Oryon core design and was optimized for Windows through collaboration with Microsoft, including the introduction of the Prism emulation layer, which allows x86/x64 applications to run on ARM. Many applications, such as Adobe Illustrator and Discord, now run natively on ARM, showing significant performance improvements. By 2026, NVIDIA unveiled the RTX Spark, an ARM-powered system on a chip, developed with MediaTek, featuring an ARM Cortex CPU and a Blackwell RTX GPU. NVIDIA also announced improvements to Windows for better workload scheduling and support for kernel-level anti-cheat software on Windows ARM.

Microsoft’s PowerToys is getting a low memory mode that kills idle utilities hogging Windows 11 RAM

Microsoft PowerToys is introducing a new optional low memory mode to address significant memory usage from inactive background processes. This feature, developed by an independent contributor, will close the helper process of specific utilities when not in use, allowing users to relaunch them with a hotkey, albeit with a slightly slower initial launch. The initial rollout will support four tools: Text Extractor, Color Picker, Advanced Paste, and Peek. A shared settings map and helper APIs have been introduced to facilitate this feature, which was renamed to “Close apps when inactive” during the code review process. Users can enable this memory-saving behavior globally or for specific applications, with each supported module featuring a toggle on its settings page. The feature is not yet available in PowerToys, and the default behavior will keep background processes running until users opt into the new feature. The code has passed initial validation checks and is awaiting final confirmation before public release.

Microsoft wants to speed up Windows 11 app launching by briefly boosting CPU frequency

Microsoft is developing a performance enhancement feature for Windows 11 called the Low Latency Profile (LLP), which aims to accelerate everyday tasks like app launches by briefly boosting CPU frequency for 1 to 3 seconds. LLP can reduce app launch times by up to 40% for Microsoft applications and improve simpler tasks like accessing the Start Menu by up to 70%. While it increases CPU usage, the short bursts are expected to have minimal impact on power consumption and heat generation. Users will not have the option to toggle LLP on or off, as it will be integrated into a future Windows 11 update. This initiative is part of Microsoft's broader Windows K2 effort to enhance performance and user experience.

Intel VP claims up to 30% of CPU performance is untapped by modern games — software optimization is critical to unlocking full potential of hybrid CPUs

Intel's transition to a hybrid architecture for its CPUs began with the Alder Lake series in 2021, combining performance and efficiency cores. Intel's Vice President, Robert Hallock, noted that while the hybrid architecture has matured, a "unified core" is still in development. He mentioned that many users disable efficiency cores (E-cores) to enhance performance, but the performance difference between using only performance cores (P-cores) and both types of cores is minimal, around 1%. Hallock explained that early implementation of Intel's Thread Director improved performance with only P-cores, and the Windows task scheduler struggles without it. He emphasized the importance of software optimization for enhancing performance, stating that a significant portion of potential performance—estimated between 10% to 30%—remains untapped due to suboptimal game optimization. AMD's approach includes integrating additional SRAM through its 3D V-cache technology, while Intel's upcoming Nova Lake will introduce a Big Last Level Cache (bLLC). Hallock indicated that developers have primarily optimized for AMD's silicon, limiting the full potential of Intel's hybrid architecture.
