Linux

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.

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:

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.
