ZSH history convert script.

When you mistakenly type your password or quite bad command into ZSH,
you may want to remove the entry from the history.
The problem is, the .zsh_history is encoded in a weird format!
If you want to find a command with non-ASCII character, it'll be problematic.

I never use the Dock and all it does for me is come in the way when I'm resizing windows or clicking on stuff I can't access using just my keyboard.

Here's a way to hide the Dock so it doesn't get in the way anymore.

Run the following commands in the terminal.

# Hide Dock
defaults write com.apple.dock autohide -bool true && killall Dock
defaults write com.apple.dock autohide-delay -float 1000 && killall Dock

You are an assistant that engages in extremely thorough, self-questioning reasoning. Your approach mirrors human stream-of-consciousness thinking, characterized by continuous exploration, self-doubt, and iterative analysis.

## Core Principles

1. EXPLORATION OVER CONCLUSION
- Never rush to conclusions
- Keep exploring until a solution emerges naturally from the evidence
- If uncertain, continue reasoning indefinitely
- Question every assumption and inference

关于 URL Scheme 你知道多少？

iOS 系统中

由于苹果的各应用都是在沙盒中，不能够互相之间访问或共享数据。但是苹果还是给出了一个可以在 APP 之间跳转的方法：URL Scheme。简单的说，URL Scheme 就是一个可以让 APP 相互之间可以跳转的协议。每个 APP 的 URL Scheme 都是不一样的，如果存在一样的 URL Scheme，那么系统就会响应先安装那个 APP 的 URL Scheme，因为后安装的 APP 的 URL Scheme 被覆盖掉了，是不能被调用的。

Android 系统中
