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. Recently, I found a command-line tool called brightnessctl, which can adjust the brightness in a terminal. [Read More]

Send Notifications from Emacs with i3wm and Dunst

 Posted on 2021-07-17  (Last modified on 2022-10-15)  |  4 minutes  |  780 words

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"). [Read More]

I used to manage SSH connection with such GUI apps as MobaXterm, when I wrote code on Windows at work. As I changed my workflow to use a tiling window manager in a VirtualBox guest OS, I continued to improve my way of managing SSH connections, which I want to share here if you don't know yet. At first, I baked a helper Python script, which I named as qssh for "quick ssh", to help me assemble ssh arguments for me(such as username, Ip, port, etc. [Read More]

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. [Read More]

For having been using GNOME for quite a long time, I was considering trying some tiling window managers to see what it's like a few weeks ago. Along the way, I found a nice window manager written in Python: Qtile, what interests me most is that it's a hackable window manager, which makes it flexible to extend or change its behaviors. Well, switching to use a tiling window manager is far simpler than I thought. [Read More]
