不是现在难用，自从 Gnome3 之后就难用了。
大约 2011 年 Ubuntu 转 Unity 桌面，其它发行版转 Gnome3 ，交互设计的和💩一样，估计是迎合当时的移动化浪潮。
再后面我就用回了 KDE 4 ，回想当年 KDE 3.5 ，KDE 4 的交互一如既往，很多优秀的体验一路延续下来，直到现在最新 KDE 6 。

当前的版本有两个配置来控制排版：

1.「候选词列表」的样式，横排和竖排
candidate_list_layout: stacked | linear

2.「候选词」的样式，横排和竖排
text_orientation: horizontal | vertical

Time Machine

和你遇到的问题一样

@hagezhou 找到解决办法了：
1. 在客户端编辑 ~/.known_hosts，将里面涉及 服务端 的条目删除
2. 执行 ssh-keyscan -p <server port> <server-host> 2>/dev/null | grep ssh-rsa >> ~/.known_hosts

客户端的：

开启看戏模式

必须 MacBook Pro，外观不说了，Retina 也不说了，就是系统的 Terminal 装上 Homebrew 就能随手打造自己的工具链了。

用 iTerm2 打开会话之后又立即关闭就会出现这种提示
OS X 下正确的自动启动姿势可以参考： launchd — 你应该了解的 OS X 工具
https://www.ulumen.com/launchd-tool-of-os-x-you-should-know-about/

大概是 PATH 变量里的路径没有包含命令所在路径

@varrily 强行硬广

通过 ssh 远程执行 mysqldump 命令，在远程用 bzip2 压缩
重定向到本地的 .bz2 文件：
ssh USER@HOST "mysqldump --all-databases --single-transaction | bzip2 " > /path/to/local/file.HOST.sql.bz2

这样一个命令就搞定了远程、加密、压缩、存储
写成脚本，通过配置文件来添加机器及数据库就好

^foo^bar
将上一命令的第一个 foo 改为 bar

安利个小工具： nc 或者 netcat

好像很不错，调研一下先~

@xqin 这个方法可靠， SSH 可以做端口隧道

温故而知新

很赞！用了很久，但是很多细节不一定能说的清楚。
