The Problem: Missing Characters in Windows ConsoleA common frustration among developers working in Windows traditional console environments (conhost.exe) involves the inability to display certain Unicode characters properly. A典型案例 is U+2717 (✗, BALLOT X)—a simple checkmark symbol that should display cleanly but instead appears as a boxed question mark when using the system's default monospace font, Consolas.This issue frequently surfaces when using modern terminal-based editors like NeoVim, which often require Nerd Fonts for proper icon rend...

Technical Information PublicationWhen AI Agents Stretch Call Chains: Latency Becomes a Business Opportunity
The Hidden Cost of AI Agent DeploymentMany teams only truly realize the expensive nature of latency after their products go live. What appears to be a simple AI Agent request on the surface often conceals an entire execution chain operating behind the scenes. Rather than a single model invocation, the system orchestrates a complex sequence: the model first interprets the task, then calls various tools, reads data from multiple sources, performs additional reasoning, invokes external APIs, and finally generates the result presented to the use...
When AI Agents Stretch the Call Chain, Latency Becomes a Business
Many development teams only realize the true cost of latency after their products have already gone live. This realization often comes too late, when users are already experiencing frustrating delays that drive them away from the application.What appears to be a simple AI Agent request on the surface actually involves a complex execution chain behind the scenes. Rather than a single model invocation, the system must orchestrate multiple sequential operations: the model first interprets the user's task, then calls various tools, reads from da...
I Distilled Myself Into an AI Skill and Open-Sourced It
Hello everyone, I'm programmer Yupi.Recently, GitHub has witnessed a surge of "distillation" projects sweeping through the developer community. And no, this isn't about distilling alcoholic beverages—this is about distilling people into digital personas.Projects with names like colleague.skill, ex-partner.skill, nuwa.skill (referencing the Chinese goddess who created humanity), boss.skill, and self.skill have emerged one after another. Everyone is busy "encapsulating" people around them into AI skill packages. Some have distilled their depar...
ASP.NET Core Memory Cache in Practice: Configuration Guide and Common Pitfalls
IntroductionIn this article, we'll explore ASP.NET Core's memory caching capabilities in depth. ASP.NET Core memory caching (IMemoryCache) represents a lightweight caching solution suitable for single-instance applications or local caching within distributed environments. It provides straightforward APIs for storing and retrieving data while supporting expiration policies, priority settings, and various other configuration options.Understanding how to properly configure and use memory caching can dramatically improve your application's perfo...
Large Model Fundamentals (Part 1): What Is an LLM?
Part 1: The Concept of Large ModelsNowadays, AI has become indispensable in our work and daily lives. But do you know what the "large models" or "AI" we talk about daily actually are? I think we can explain this from both narrow and broad dimensions.When discussing large models, we often hear the concepts of "narrow large models" and "broad large models," representing different scopes of understanding about large models.Narrow Large Models: Specifically Referring to Large Language Models (LLM)In the narrow sense, large models typically speci...
