How to get coloured terminal over ssh?

I haven't used my old MBP 13 for nearly a month. This evening I picked it up and opened the iTerm2 then connected to my home server through ssh. I noticed I get a white-black colored terminal. What's wrong? I remembered it was colorful when I logged into this machine last time using iTerm2 on my MBP 15.

Firstly, I checked the version of iTerm2, it was a bit old, so I updated it first. Unfortunately, it doesn't help. I noticed I was using bash instead of zsh on this machine. So I ran chsh and changed the shell from bash to ssh. It also doesn't help. Then I find this answer from stackoverflow.com. A comment in this answer reminded me: I should check and compare the terminal configuration in iTerm2. So I found the secret!

Command + , open the preference, then click the profiles tab, then change the Report terminal type from xterm to xterm-256 color, that's it!

Set done a simple automatically backup system for this site

I didn't forget I haven't set up a backup system for this blog site. So I got it done today.

Two things need to backup, they are

  1. the MySQL database
  2. the uploads directory that contains the pictures, files you've uploaded to this site

Since local backup is not safe, finally I chose the Yandex.Disk as my cloud storage. Just register an account in 5 minutes and you will get 10G cloud storage with Linux friendly sync feature. Yandex.Disk also supports symbol links, that's quite good.

run crontab -e and fill in below lines, the setting was done!

 15 3 * * * mysqldump --databases blog | gzip > /home/zhongwei/Yandex.Disk/backups/mysql/blog_`date '+\%Y\%m\%d-\%H\%M\%S'`.sql.gz
 20 3 * * * find /home/zhongwei/Yandex.Disk/backups/mysql/blog* -mtime +30 -exec rm {} \;

As the uploads folder for my blog, what you need to do is creating a symbol link to the Yandex.Disk folder:

ln -s /www/blog/uploads /home/zhongwei/Yandex.Disk/backups/blog_uploads

麻雀

这些天受疫情影响，我只能在家工作。我的工作台的右侧，就是正门门前的那块空地。平常我们都是使用后院的门，正门极少使用。这块空地就成了麻雀经常光顾的地方。

而我呢，工作累了，或者想偷懒的时候，往右一瞥往往就会看到它们或者在玩，或者在吃东西。虽然并没有人惊吓它们，但我却感到它们不像新西兰别的鸟。那些鸟大多大大咧咧的不怎么怕人，甚至懒得飞，即使你驱赶它们，它们也经常用快跑代替飞。麻雀总是警觉的，不论是吃还是玩，都是玩一秒钟或者吃两秒钟，就赶紧四顾看看有没有危险。我从没有看到过它放松的时刻。

这么警觉的动物会活得很长吧，并不。日日过着担惊受怕的生活，怎么可能长寿呢。查了一下，果然。普通麻雀在野外的寿命也就三年。

可爱又可怜的小精灵啊。

Watched "WALL-E"

with Eric yesterday evening. This is the second time I watched it. A moving film about two lovely robots.
