The article analyzes Huawei’s Ascend AI chip roadmap, detailing the progression from the 910C baseline to the 950, 960/970 generations, highlighting compute scaling, low‑precision formats, memory and interconnect upgrades, cost advantages, and their implications for large‑model AI workloads.
The article explains how Linux’s page cache bridges memory and disk, detailing its read/write mechanisms, dirty page handling, pre‑read optimization, kernel parameters, and practical tuning tips for static file serving, databases, and logging, showing why mastering it is essential for performance.
This guide compiles free large‑language‑model APIs from official vendors and third‑party platforms, detailing each service's token quotas, rate limits, base URLs, usage restrictions, and available models, while offering practical advice on token optimization, multi‑platform rotation, rate‑limit handling, and key security.
The article analyzes how leading internet companies embed AI agents across the entire data‑warehouse lifecycle to automate governance, presenting real‑world case studies from Alibaba, ByteDance, JD.com and Tencent, and quantifies benefits such as over 65% reduction in manual effort, 50% drop in metric duplication, and a 40% boost in resource utilization.
This article walks through constructing a tiny, runnable AI agent loop that reads a user task, lets the model choose the next step, calls a tool, feeds the observation back, and repeats, then explains how to add harness, memory, permission, and validation layers to make the agent reliable in real‑world engineering environments.
This article examines five typical pitfalls when using Spring Boot filters—request body consumption, ThreadLocal leakage, duplicate execution, ordering conflicts, and async handling—provides concrete code examples, explains why each issue occurs, and offers reliable solutions to keep your applications stable and secure.
Analyzing 200 AI product‑manager job ads reveals that 70% of roles don’t require deep AI knowledge, salaries depend more on industry expertise than technical depth, prompt engineering has become a baseline skill, and the most valuable talent are those who can ship end‑to‑end AI products.
The article explains how AI product managers have shifted from creating prototype diagrams to designing continuous evaluation “exams”, using real‑world examples, data‑driven testing, cross‑team collaboration, and iterative error analysis to deliver truly useful AI products.
The article explains how the emerging "Harness Engineering" paradigm—highlighted by OpenAI, Stripe and Anthropic—shifts AI development from prompt tweaking to building full control systems, promising ten‑fold efficiency gains, new architectural components, and both opportunities and risks for developers.
The article analyzes Agent memory design by comparing human short‑term and long‑term memory, explains context‑window management strategies, outlines persistent storage options such as vector databases, relational stores, knowledge graphs and fine‑tuning, and presents a three‑layer architecture with write, retrieval and forgetting mechanisms.
The article analyzes why memory is essential for practical LLM agents, categorizes four memory types, proposes a perception‑judgment‑refinement‑storage pipeline, introduces a three‑dimensional retrieval scoring model, and outlines a three‑layer architecture with reflection, merging, and forgetting mechanisms.
