Adjust the screen brightness in Emacs

If you're using i3wm on Linux, how do you adjust the laptop's screen brightness?

Most of the time, I use the laptop with an external monitor. But when I am out, I have no monitors. And it seems no easy way to adjust the brightness in i3wm. Being too bright or dim is terrible for the eyes.

How to Reload i3status config On the Fly

Sometimes I want to change the status (i3status) of i3wm temporarily, but it seems that i3wm doesn't support it directly, although reloading the config for i3wm itself is a piece of cake (bindsym $mod+Shift+c reload in the config, or i3-msg -t command reload in the command line).

But this issue scratched my itch, and I swear that I must solve it today.

BTW, I'm improving my English by watching YouTube videos every single day; If you're also learning English, or any languages, LanguagePuppy can definitely help you. It's a Chrome extension I developed using Clojure. Check it out:

Send Notifications from Emacs with i3wm and Dunst

I barely use notifications, but recently I think it's a valuable way to remind me things like helping me nurture habits, or to notify me of emergencies like a critically low laptop battery.

So I try to integrate notifications to org-mode and Emacs today.

The org-notify package from org-contrib (install it by (package-install 'org-contrib) ) could do this job easily before, so I first test it in the minibuffer with (org-notify "test").

Unfortunately, it errors out:

I have been really enjoying the more concentration workflow qtile, a tiling window manager, brings me, since I started using it a few months ago. I am more focus on the current task now as all the windows I care about are laid out on the same screen.

As I get more used to qtile at every day's work, I noticed that I became more depend on short-life terminal sessions. Sometimes I need to quickly execute some commands on the current buffer on Emacs, such as searching text which having many matches and quit that terminal after I'm done. So I wondered what could be the best way to achieve that.
