    Visual Studio 2026 is here: faster, smarter, and a hit with early adopters

    Visual Studio 2026 is now generally available with significant performance improvements, including 50% fewer UI hangs and faster startup times. The release introduces AI-native features through GitHub Copilot integration, including new C# and C++ agents for debugging, profiling, and app modernization. Over 5,000 bugs were fixed and 300 feature requests implemented based on community feedback. The IDE now decouples from build tools, allowing updates without affecting .NET or C++ compilers, and maintains full compatibility with Visual Studio 2022 projects and over 4,000 extensions.

    VS Code Planning mode

    VS Code now includes Planning mode (also called 'Hannibal mode'), which extends GitHub Copilot's Agent Mode to handle multi-step coding tasks with a structured approach. Unlike Visual Studio's implementation, VS Code offers Planning mode as a separate chat agent, giving developers explicit control over when it's activated. The feature creates detailed execution plans before generating code, allows plan editing, and includes follow-up questions to refine the approach before implementation begins.

    Highlights from Git 2.52

    Git 2.52 introduces several performance improvements and new features. The release adds git last-modified for efficient tree-level blame operations (5x faster than previous methods), a new geometric maintenance strategy for large repositories, and experimental git repo command for repository information. Notable additions include git refs list and git refs exists subcommands, optional Rust support for internal functionality, enhanced Bloom filter support for pathspec queries, and git sparse-checkout clean for recovery scenarios. The release also prepares for Git 3.0 changes, including SHA-256 as default hash algorithm and 'main' as default branch name.

    Vibe Coding: Build A Complete App From Scratch In Minutes Using GitHub Copilot.

    A senior engineer shares their journey from skepticism to adoption of GitHub Copilot after testing it on tutorial projects. They demonstrate building a Flutter app called "Mood Mixer" that captures selfies, detects emotions, and generates Spotify playlists using only AI prompts and no manual coding. The piece explores how AI tools can serve as effective assistants for scaffolding, state management, and function improvements rather than complete replacements for developer skills.

    Level up design-to-code collaboration with GitHub’s open source Annotation Toolkit

    GitHub open sourced the Annotation Toolkit, a Figma library that improves design-to-code handoffs by embedding accessibility documentation directly into design files. The toolkit uses numbered annotation stamps to document design intent, WCAG compliance requirements, and interactive behaviors, preventing accessibility issues before they reach production. GitHub's internal data showed 48% of accessibility audit issues could have been prevented with better upfront documentation. The toolkit is available on Figma Community and GitHub, includes interactive checklists and WCAG guidance, and accepts community contributions.

    Microsoft for Python Developers Blog

    The November 2025 Python extension for VS Code introduces several productivity enhancements: AI-generated hover summaries can now be inserted directly as docstrings, Copilot summaries support localization, a new code action converts wildcard imports to explicit imports for better code clarity, and the debugger now supports multiple interpreters per workspace through the Python Environments Extension. Additional improvements include better PowerShell activation handling and enhanced Poetry and requirements file detection.

    "2026", AI Users vs The Unemployed.

    Explores the dramatic shift in software development as AI-generated code approaches 90% of all code by 2026. Examines the impact on developer careers, particularly junior positions, the changing job market with 200-300 applications per role, and the compression of development teams. Discusses quality concerns including doubled code churn and security vulnerabilities, while questioning how developers can remain relevant when AI handles most coding tasks. Argues the profession is fundamentally transforming from writing code to directing AI and reviewing its output.

    Putting Spec Kit Through Its Paces: Radical Idea or Reinvented Waterfall?

    Spec-Driven Development (SDD) proposes using detailed specifications as the source of truth for AI agents to generate code. Testing this approach with Spec Kit on a real feature rebuild revealed significant drawbacks: excessive markdown generation (2,500+ lines), long agent execution times (33+ minutes), and 3.5 hours of review overhead. Traditional iterative prompting proved 10x faster, completing the same work in 8 minutes of agent time with minimal review. The workflow felt like a return to waterfall methodology, producing duplicative documentation without improving code quality or reducing bugs. While SDD presents interesting ideas worth discussing, the practical implementation through Spec Kit doesn't capitalize on AI's strength of making code cheap and fast to produce.

    3 MCP servers you should be using (safely)

    Model Context Protocol (MCP) enables AI models to interact with developer tools and services through standardized servers. Three essential MCP servers are highlighted: Kubernetes for cluster management and diagnostics, Context7 for accessing up-to-date technical documentation, and GitHub for repository interactions. Each server requires careful security configuration, including read-only defaults, human approval for write operations, and minimal access tokens to prevent data exfiltration through prompt injection attacks.

    Copilot .Net modernization tool a 'huge downgrade,' devs say – and no longer free • DEVCLASS

    Microsoft replaced the free .NET Framework upgrade assistant with GitHub Copilot app modernization, requiring a paid subscription. Developers report the new AI-powered tool is inferior to its predecessor, with issues including incomplete migrations, hundreds of hours of manual fixes, and less deterministic results. The old upgrade assistant remains accessible through Visual Studio settings, while Microsoft also introduced Managed Instance on Azure App Service for applications that cannot easily migrate to modern .NET.

    Migrating Dillo from GitHub

    The Dillo browser project is migrating away from GitHub to a self-hosted infrastructure at dillo-browser.org. The move addresses GitHub's JavaScript-heavy frontend that doesn't work with Dillo itself, single point of failure concerns, and performance issues. The new setup uses cgit for repository hosting, a custom Markdown-based bug tracker called buggy, and maintains mirrors on Codeberg and Sourcehut. All critical data is stored in git repositories with OpenPGP signatures for authenticity, enabling resilience against domain loss and reducing dependency on any single platform.
