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.

Windows devs rerolled old code to save precious bytes

Veteran Microsoft engineer Raymond Chen shared a story about the development of an x86-32 emulator that utilized binary translation, significantly improving performance compared to traditional emulation methods. During the project, the team faced an issue where a function allocated 64 KB of memory but was optimized by a compiler into 65,536 instructions, leading to 256 kilobytes of code being used to initialize the data. In response to this inefficiency, the engineers modified the translator to replace the inefficient function with a more compact loop, highlighting their commitment to memory efficiency during a time when operating systems prioritized resource conservation.

Engineer builds Minecraft phonics game with AI

Alex O'Callaghan created a Minecraft-themed phonics game during a conversation with the AI model Claude. The game has two modes: one for picture-to-spell using letter tiles and another for read-to-picture with four images, targeting Key Stage 1 phonics. He developed the project further using Claude Code, set up Vite for development, integrated Vitest for testing, and switched to TypeScript. O'Callaghan enhanced the game's visuals by using a comprehensive npm package for Minecraft item sprites. His son engaged with the game and contributed content suggestions, improving their connection and motivation to practice phonics.

How to Use Meta AI on Meta Apps

Meta AI is integrated into WhatsApp, Instagram, Facebook, and Messenger, providing functionalities like chat, search, image generation, and automated customer support through the Meta Business Agent. Its availability varies by country, account type, app version, and language. Users should be aware that seeing a colleague's blue Meta AI ring in WhatsApp while they do not may indicate a rollout flag on Meta's end rather than an app malfunction. Meta AI can answer queries, suggest ideas, generate images from prompts, clarify messages, assist with searches, and support customer interactions for business accounts. It is linked to the Llama model family, including Llama 2 and Llama 3. To use Meta AI on WhatsApp, users need to update the app and can start a chat by locating the Meta AI button or circle. They can ask practical questions, request image generation, and utilize it in group chats. On Instagram, it enhances DMs and search functions, allowing users to create AI chats for content ideas and captions. In Messenger, there is an "Ask Meta AI" bar for direct interactions. Users can also utilize Meta AI on Facebook for search and content discovery. The Meta Business Agent is a version of Meta AI for businesses, providing 24/7 responses to customer inquiries. It can be set up in Meta Business Suite or WhatsApp Business. Privacy measures should be considered, as users cannot entirely disable Meta AI and should avoid sharing sensitive information in chats. For better responses, users should provide context and constraints in their prompts and consider training in prompt design and AI risk management for professional use.

PostgreSQL vs SQL Server 2026: $0 vs $15K License

PostgreSQL has become the most utilized database for developers for two consecutive years as of 2026, while SQL Server has introduced native AI capabilities and vector search functionalities in its latest release. PostgreSQL is favored for new projects due to its permissive licensing, cross-platform operation, and extensive ecosystem of extensions, whereas SQL Server is preferred by organizations already using Microsoft products for its robust tooling and enterprise support. As of June 2026, SQL Server ranks third in the DB-Engines popularity ranking with a score of 698, while PostgreSQL ranks fourth with a score of 688. Developer adoption trends show that 49% of respondents in the Stack Overflow 2024 Developer Survey use PostgreSQL, compared to 27% for SQL Server. The latest stable version of PostgreSQL is 18.4, released on May 14, 2026, while SQL Server 2025 (version 17.x) became generally available on November 18, 2025. PostgreSQL is free under a permissive license, while SQL Server's Enterprise Edition can cost upwards of ,123 per two-core pack, with an eight-core minimum. PostgreSQL supports various operating systems, including Linux, Windows, macOS, and BSD, while SQL Server operates on Windows and Linux. PostgreSQL uses PL/pgSQL as its primary procedural language, allowing for multiple procedural languages, whereas SQL Server uses T-SQL. PostgreSQL's JSONB type offers rich indexing, while SQL Server added native JSON support in its 2025 release. Both databases are capable of handling high transaction volumes, but PostgreSQL excels in read-heavy scenarios due to its multi-version concurrency control, while SQL Server's columnstore indexes provide advantages for analytical workloads. PostgreSQL supports tables up to 32 TB, while SQL Server can handle a maximum database size of 524 PB. SQL Server's high availability technology includes Always On Availability Groups, while PostgreSQL offers built-in streaming and logical replication. The security features of both databases meet enterprise standards, with PostgreSQL providing a transparent patching process and SQL Server integrating with Microsoft tools. Real-world usage examples include Stack Overflow using SQL Server, while Instagram and Reddit utilize PostgreSQL. Developer sentiment increasingly favors PostgreSQL for new projects, emphasizing flexibility and open-source solutions.

Windows 8’s codename was “Modern Experience” — Microsoft says it lacked creativity

Raymond Chen, a Microsoft software engineer, reflected on the development of Windows 8, which was announced on June 1, 2011, and had its support withdrawn on January 12, 2016. The development team initially referred to Windows 8 as "the modern experience" to distinguish it from Windows 7, known as "the classic experience." This led to the creation of abbreviations like "MoSh" for the modern shell and "ClaSh" for the classic shell. Other terms included "MoGo" for the new Start menu and "MoSet" for the settings control panel. Microsoft has since introduced Windows K2, an internal project aimed at addressing issues in Windows 11, and has made changes based on user feedback, such as allowing indefinite postponement of updates. Users can engage in discussions about Windows K2 on Reddit at r/WindowsCentral.

Microsoft’s veteran engineer says Windows 8 was all built around “modern” codenames — including the polarizing Start menu

Microsoft unveiled Windows 8 on June 1, 2011, and ceased support for it on January 12, 2016. During its development, the team referred to it as "the modern experience" to distinguish it from Windows 7, known as "the classic experience." The new shell was called "modern shell" or "MoSh," while the old shell was referred to as "classic shell" or "ClaSh." The Start menu was initially called "Go page" and later renamed "MoGo." Other components were similarly named, such as "MoSet" for the settings control panel and "MoCo" for the ListView control. Microsoft is currently working on a project called Windows K2 to address issues in Windows 11, allowing users to postpone updates indefinitely and reducing the visibility of Copilot based on feedback. A status tracker for Windows K2 is available.
