The article provides a comprehensive introduction to Embedded Swift, a new compilation mode in Swift 6 designed for microcontrollers and real-time systems. It begins by highlighting the persistent challenges of traditional C/C++ development, such as manual memory management and unsafe pointer operations. The author then positions Embedded Swift as a modern solution offering memory safety, strong type checking, and deterministic performance, drawing comparisons with C/C++. Key features like Automatic Reference Counting (ARC) for memory management, Protocol-Oriented Programming (POP) for modularity, and Swift's modern syntax are detailed, emphasizing their benefits for embedded contexts. The article delves into the trade-offs of ARC, discussing its memory and CPU overhead compared to C's manual approach, while also noting how aggressive compiler optimizations can mitigate these costs. Practical aspects such as setting up the toolchain for STM32 microcontrollers and interoperability with existing C drivers are covered, making it highly relevant for developers. The piece concludes by underscoring Swift's potential in the future of embedded development, driven by the industry's shift towards memory-safe languages.
This article deeply analyzes the current dilemma of "spaghetti code" faced by large language model (LLM) system prompts, namely engineering problems such as rule collisions caused by the unordered accumulation of rules, difficulty in maintenance, and dilution of core values. The author highlights that significant technical debt may underlie seemingly 'god-level' prompts. To solve this problem, the article proposes introducing system architecture thinking and essentially regarding the prompt as a blueprint for a virtual intelligent system. The article elaborates on the four-layer architecture model composed of Core Definition, Interaction Interface, Internal Processing, and Global Constraints, providing a clear and structured framework for prompt design. In addition, the article summarizes six compilation principles to guide how to effectively transform this rigorous architecture blueprint into prompt text that LLMs can understand and execute stably, thereby upgrading prompt engineering from a craft to software engineering and realizing a fundamental shift from managers of rules to designers of intelligent systems.

Furthermore, it outlines Cursor's sophisticated cloud infrastructure, detailing the roles of various providers like AWS, Azure, GCP, OpenAI, Anthropic, and specialized services like Turbopuffer for vector embeddings, all designed to handle immense scale while prioritizing data security and user privacy.
The article details the newly released open-source flagship model GLM-4.5 series by Zhipu. Designed for agent applications, this series of models (including GLM-4.5 and GLM-4.5-Air) adopts a Mixture of Experts (MoE) architecture. The article emphasizes that GLM-4.5 has reached the SOTA level among open-source models in reasoning, code, and agent comprehensive capabilities, and performs excellently in multiple benchmark tests, especially demonstrating the best performance among domestic models in human evaluations of real-world code agents. In addition, the model has achieved significant optimization in parameter efficiency, API call costs, and generation speed, providing an input price as low as 0.8 yuan/million tokens and a generation speed of up to 100 tokens/second. The article also showcases the application effects of GLM-4.5 in real-world scenarios such as full-stack development, Artifact generation, and PPT creation, and provides API, open-source repository, and online experience addresses for developers and users to test and integrate.
The article introduces GitHub's managed Model Context Protocol (MCP) endpoint as a superior alternative to running the MCP server locally. It highlights key benefits such as automated updates, simplified OAuth authentication instead of manual PAT management, and broader accessibility from any IDE or remote-dev box. The managed service eliminates infrastructure headaches like Docker maintenance, allowing developers to focus on coding and leveraging richer AI workflows. The guide provides a step-by-step tutorial for installation on VS Code and other clients, demonstrating how to configure access controls like read-only modes and dynamic toolsets for enhanced safety and efficiency. It showcases practical examples of GitHub Copilot Agent's capabilities with the managed server, including automating CODEOWNERS file creation, debugging failed CI/CD workflows, and triaging security alerts. The article also previews future developments like secret scanning and agent-to-agent collaboration, emphasizing the open-source nature of the GitHub MCP project. Ultimately, it positions the managed MCP server as a foundational tool for advanced, automated developer workflows.
This article presents an interview with Saoud Rizwan and Nik Pash, the founders of Cline, an open-source AI coding agent distributed as a VS Code extension, following their recent $32 million funding round. Cline differentiates itself in the crowded AI coding space by introducing a 'Plan & Act' paradigm, where the AI first formulates a comprehensive plan before executing tasks, moving beyond simple sequential chat. A key technical innovation highlighted is its shift from traditional RAG (Retrieval-Augmented Generation) for codebase indexing to 'agentic search,' underpinned by advanced 'context engineering' practices. These practices include dynamic context management, AST-based analysis for precise code extraction, maintaining narrative integrity across tasks, and developing a memory bank for persistent knowledge. The discussion also emphasizes Cline's modular architecture via 'MCPs' (Modular Code Providers), which enable seamless integration with various tools like file systems, browsers, Git, and third-party services. Surprisingly, MCPs have expanded Cline's utility to non-technical users for workflow automation, such as social media content generation and presentation creation. The founders explain their strategic decision to build on VS Code as an extension rather than a fork, citing benefits in distribution, onboarding friction reduction, and maintenance. The interview concludes by reinforcing Cline's commitment to the agentic programming paradigm as the future, simplifying complex development tasks through natural language interaction.

This article records a roundtable discussion from Tencent Research Institute's 'Midsummer Six Days Talk,' exploring the information ecosystem shift from 'Information Cocoon' to 'Information Beehive.' The discussion traces the connection between the 'My Daily' concept and the Information Cocoon and analyzes the existence, types, and causes of Information Cocoons, highlighting the combined effects of user cognitive bias, inertia, and algorithms. The guests (Hu Yong, Yang Jian, Huang Chenxia) emphasized that 'Information Cocoon' should be regarded as a hypothesis in academia, rather than an established theory, and mentioned the potential 'Hallucination Cocoon' trap from Large Language Models. The article critically examines the limitations of solely relying on technology to solve the Information Cocoon, calls for the reconstruction of the 'Information Gatekeeper' role, and re-evaluates the value of 'Legacy Internet' mechanisms such as RSS Subscription, Search Engine, and BBS, believing they offer potential paths to resist Information Cocoons. Ultimately, the article envisions the 'Information Beehive' as a diverse, transparent, and collaborative information ecosystem, emphasizing the need to jointly construct it from multiple dimensions of audience, algorithms, content, and social environment.
