Windows NT 4 went on sale 30 years ago today

Microsoft Windows NT 4.0 was officially released on August 24, 1996, marking its 30th anniversary today. Codenamed “Tukwila,” it integrated the Windows Explorer desktop from Windows 95 with the NT operating system. Windows 95 was released a year earlier on August 24, 1995, and was initially codenamed “Chicago.” Windows NT 4 incorporated a modern user interface while maintaining the reliability of the NT kernel. It introduced features like the journaling NTFS filesystem but had limitations such as stability issues due to changes in the Graphics Device Interface (GDI) and lack of support for FAT32 and USB interfaces. Despite these shortcomings, NT 4 was a significant operating system that contributed to the competitive landscape of operating systems.

Microsoft reveals why Windows 11 keeps saying a file is in use after you close the app, plus the fix

The 'file in use' error in Windows indicates that a file is currently being accessed by a program, preventing deletion or renaming to avoid data corruption. This error can persist even after closing an application due to reasons such as antivirus software scanning the file, network references from other devices, or files loaded as Dynamic Link Libraries (DLLs) that remain in memory. To identify the process causing the error, Mark Russinovich developed the command-line tool Handle, which shows all open file handles, and Process Explorer, which provides a graphical interface to find and manage these handles. Microsoft is integrating Sysinternals tools into PowerToys for easier access, including the File Locksmith tool that allows users to unlock files directly. A recommended workaround for the error is to rename the file instead of deleting it, as Windows permits renaming even when a file is open.

Databricks boosts Postgres writes 5x

Databricks has enhanced its managed Postgres service using lakebase architecture, achieving write throughput improvements of up to five times. Traditional Postgres durability mechanisms, such as full page writes (FPW), impose overhead that can inflate Write-Ahead Log (WAL) volume by up to 15 times in write-heavy scenarios. The lakebase architecture decouples compute from storage, allowing compute nodes to stream WAL records to a distributed quorum of safekeepers, mitigating the risk of torn pages. Databricks has addressed read performance challenges by transferring image generation to the storage layer, which reconstructs data pages by identifying the latest materialized image and replaying corresponding WAL deltas. This results in a 94% reduction in WAL traffic and significant performance enhancements, with write throughput increasing by over 4.5 times on a 32-vCPU instance and WAL generation decreasing from 58KB per transaction to under 4KB. In production settings, steady-state WAL generation dropped from 30 MB/s to 1 MB/s, and read latencies improved by 30% to 50%. The optimization has been seamlessly integrated across Databricks' Serverless and Neon databases without requiring restarts or interruptions for customers.

Database Branching in Postgres: Git-Style Workflows with Databricks Lakebase

Database branching is a modern approach that addresses the limitations of traditional database management in development workflows. Unlike conventional database copies, which require significant time and resources to duplicate data and schema, database branching allows for the creation of isolated environments that share the same underlying storage. This method utilizes a copy-on-write mechanism, enabling branches to be created in seconds regardless of database size, with storage costs tied only to the changes made. Key features of database branching include: - Branch creation time: Seconds, constant regardless of database size. - Storage cost: Proportional to changes only, not the total data size. - Isolation: Each branch has its own Postgres connection string and compute endpoint. - Automatic scaling: Idle branches can scale compute to zero, incurring costs only when active. The architecture supporting this approach separates compute from storage, allowing multiple branches to reference the same data without conflict. This design facilitates time travel capabilities, enabling branches to be created from any point in the past for instant recovery and inspection. Database branching unlocks new workflows, such as: - One branch per developer, providing isolated environments for each engineer. - One branch per pull request, automating branch creation and deletion tied to PRs. - One branch per test run, provisioning fresh databases for each CI pipeline execution. - Instant recovery from any point in time within a designated restore window. - Ephemeral environments for AI agents, allowing programmatic database provisioning. Databricks Lakebase offers this database branching capability, transforming the database from a bottleneck into a streamlined component of the development process.

Introducing PostgREST, a REST API for any PostgreSQL database written in Haskell

PostgREST is a web server developed in Haskell that converts PostgreSQL databases into RESTful APIs, offering a more efficient and standards-compliant alternative to manual CRUD programming. It achieves subsecond response times for up to 2000 requests per second, utilizing the Warp HTTP server and offloading tasks like JSON serialization and data validation to the database. Authentication is managed through JSON Web Tokens (JWT), with authorization based on database-defined roles. PostgREST avoids using Object Relational Mappers (ORMs) and encourages declarative constraints in databases to maintain data integrity. User feedback has been mostly positive, although some have expressed concerns about complexities in production environments.

Microsoft’s ReFS File System Remains Inaccessible to Windows 11 Users

Microsoft's Resilient File System (ReFS) supports volumes up to 35 petabytes and offers robust data protection through checksums and continuous integrity checks, reducing the risk of data corruption. However, Windows 11 defaults to the NTFS file system, requiring users to use command-line tools to access ReFS features, which may deter average consumers. ReFS is primarily designed for Windows Server environments and has not gained popularity among general users. Testing shows that Windows 11 formats new drives as NTFS, making ReFS less accessible. ReFS can experience performance degradation on single-drive consumer PCs compared to NTFS and lacks features like file system compression, encryption, object IDs, and extended attributes, raising compatibility concerns. Microsoft has introduced the Agent Launchers framework for AI agent registration in Windows, amidst user backlash regarding the evolution of Windows into an "agentic OS." The Windows and Devices segment generated .3 billion in the last fiscal year, remaining flat over three years, while Gaming and LinkedIn generated higher revenues. Users have reported frequent feature changes and declining quality in Windows 11, with Microsoft's Controlled Feature Rollout system causing inconsistencies across devices. ReFS is accessible through the Dev Drive feature in Windows 11, which prioritizes performance over security. Microsoft faces competition from various fronts, including Valve's SteamOS, Apple's upcoming MacBook, and Google's Chrome OS, particularly in the education sector.
