This is the sixth part of the Claude Code Mastery Guide. In the previous part, we configured an expert team for Claude Code. In this part, we'll equip it with external devices, transforming it from a local assistant into an internet platform.A vivid analogy: Claude Code without MCP configuration is like a genius locked in a room.It's smart, efficient—capable of handling all the files you throw at it, but can't reach anything in the outside world. You can't ask it to "go fetch the details of that Issue on GitHub," can't have it "take a look a...
Ghostty-Based Terminal with Split Tabs and Notifications Designed for Claude Programming
When running Claude Code with macOS's built-in terminal, you need to open many Terminal windows when starting大量 sessions.In most cases, we hand over requirements to Claude and switch to do other things. When we return much later to check, it might show Claude asking whether you agree to some operation.If you're doing frontend development, after Claude generates code, you still need to switch to the browser window to start the preview.There's a macOS terminal tool that meets all your needs—cmux.If you also want to preview and edit files direc...
ASP.NET Core Memory Cache in Practice: The Complete Guide to Configuration and Pitfall Avoidance
IntroductionIn this article, let's talk about ASP.NET Core's memory caching. ASP.NET Core Memory Cache (IMemoryCache) is a lightweight caching solution suitable for single-instance applications or local caching in distributed environments. It provides a simple API for storing and retrieving data while supporting expiration policies, priority settings, and other features.What Is Caching?From user request to database returning data, this is a long process (exaggerating a bit—usually just tens to hundreds of milliseconds). But there's more than...
I Distilled Myself Into an AI Skill—And Open-Sourced It!
Hello everyone, I'm programmer Yupi.Recently, GitHub has seen a wave of "distillation" enthusiasm.Not distilling liquor, but distilling people.Colleague.skill, Ex.skill, Nuwa.skill, Boss.skill, Self.skill... Various bizarre distillation projects are emerging one after another. Everyone is "encapsulating" people around them into AI skill packages.Some people distilled their departed colleagues, letting AI continue doing their work; some distilled their ex-partners, chatting with the AI version to recall old memories; some even created an "Ant...
Why conhost.exe Cannot Display U+2717: A Deep Dive into Windows Console Font Rendering
I wanted to display U+2717 (✗, BALLOT X) in the Windows traditional console (conhost). With the system's default monospace font Consolas selected, what appeared was a boxed question mark. I encountered this symbol while using NeoVim, which also requires Nerd Fonts, but even many fonts that support Nerd Fonts don't support this character.The cause of the problem is obvious: Consolas doesn't contain this glyph—just switch to a font that includes it. After consulting fileformat.info's glyph support list, I discovered that open-source monospace ...
When AI Agents Stretch the Call Chain, Latency Becomes a Business
Many teams only realize the true cost of latency after their product goes live.What appears to be a simple AI Agent request often involves not a single model invocation, but an entire execution chain behind the scenes: the model understands the task, calls tools, reads data, performs additional reasoning, invokes external APIs, and finally generates results. Users see only one response, but the system may have traveled back and forth between different services a dozen times.If each step adds just a bit of wait time, the cumulative result can...
