Installing tmux-256color for macOS

• macOS 10.15.5
• tmux 3.1b

macOS has ncurses version 5.7 which does not ship the terminfo description for tmux. There're two ways that can help you to solve this problem.

The Fast Blazing Solution

Instead of tmux-256color, use screen-256color which comes with system. Place this command into ~/.tmux.conf or ~/.config/tmux/tmux.conf(for version 3.1 and later):

傅立叶变换的物理意义

原创 2016-04-08 yangboy2

昨天我们分享了一篇《FFT结果的物理意义》一文，有些网友表示看不大明白，为此我们整理重发一篇去年分享过的《傅里叶变换的物理意义》一文，以便大家更好的理解。

1. 先看下面的两幅动画，增加对傅立叶变换的印象
