DBtune autonomous optimization blows PostgreSQL bottlenecks away

DBtune, a startup based in Malmö/Lund, Sweden, was founded in 2020 by Dr. Luigi Nardi as a spin-off from Stanford University and Lund University. The company focuses on enhancing PostgreSQL's capabilities through autonomous database optimization technology and has raised .4 million in a seed round from various investors in July 2023, with support from the Wallenberg Foundation and Vinnova. DBtune's technology utilizes agentic AI for optimizing PostgreSQL databases by tuning server parameters, optimizing indexes, and monitoring autovacuum processes. The release of DBtune version 4.0 incorporates machine learning and AI to dynamically adjust server parameters and suggest optimal indexing strategies. The platform identifies and ranks potential index opportunities based on workload and provides recommendations for new indexes and maintenance of existing ones. A case study with Midwest Tape demonstrated a 10.8x performance improvement in database query runtime after employing DBtune for performance tuning. Benchmarking tests showed a transaction throughput increase of 87% during initial optimization, with a further 17% improvement on an already optimized system. Disk I/O activity was reduced by 43%, and WAL generation decreased by 23%. Dr. Nardi emphasizes the need for AI-driven optimization to manage the complexities of PostgreSQL databases and rising cloud costs, suggesting that significant code adaptations will be necessary for achieving fully autonomous PostgreSQL.

Copilot Gets Control of Windows and Your Files as Microsoft’s Recall Bill Comes Due

Microsoft is requesting Windows users to grant its Copilot feature access to their files and activities, following a previous retraction of a similar AI integration due to scrutiny. Copilot can analyze content on the device with user consent, performing tasks like organizing files and troubleshooting, using both local AI models and cloud processing. Microsoft has implemented safeguards, but its security team has raised concerns about potential risks associated with powerful features. The opt-in nature of Copilot places accountability on Microsoft, as users must actively grant access. Hybrid features are set to roll out in the coming months, with taskbar search actions already reaching Windows Insiders. Over 40 percent of new business laptops are being designed as Copilot+ PCs, with the Surface Laptop Ultra scheduled for release on October 16.

Microsoft Azure CTO used AI to port 20-year-old Windows tool to macOS in two days: “I was flabbergasted”

Mark Russinovich, the Chief Technology Officer of Microsoft Azure, transitioned ZoomIt, a Windows tool for screen zooming, recording, and annotation, to macOS using artificial intelligence. Originally developed to aid in teaching Windows Internals, ZoomIt has been enhanced over the years with features like screen recording and webcam overlays. Despite initial reluctance due to time constraints, Russinovich utilized AI to create a functional macOS version in just two days, significantly faster than anticipated. The AI model leveraged the original Windows code, allowing for a high-fidelity clone of ZoomIt that includes essential features. ZoomIt for macOS is now available as a free and open-source tool, requiring macOS 14 Sonoma or newer, and can be installed via Homebrew or from Microsoft’s GitHub repository. Users can access its functionalities through keyboard shortcuts and a menu bar icon.

Microsoft Sets October 7 Event to Detail Local AI Push for Windows and Surface

Microsoft will unveil its vision for the future of personal computing at an event in San Francisco on October 7 at 10 a.m. Pacific time, focusing on the role of on-device artificial intelligence in Windows and Surface hardware. Key figures including CEO Satya Nadella and NVIDIA CEO Jensen Huang will discuss innovations across Windows, NVIDIA RTX Spark, and the PC ecosystem. The RTX Spark platform, introduced earlier this year, features a system-on-a-chip with 128GB of memory, an NVIDIA GPU, and an Arm-based CPU for high-performance AI workloads. Microsoft has announced the Surface Laptop Ultra, built on the RTX Spark platform, but details on pricing and release dates are not yet available. The event will emphasize how local AI will shape the future of PCs, with a focus on hardware capable of running AI models directly on devices. Attendees can also expect enhancements to the Windows operating system, though a surprise announcement regarding Windows 12 is unlikely. The event will be streamed live, starting at 10 a.m. PT and 1 p.m. ET.
