🐇 While checking macos-option-as-alt as a potential source of the problem, I spent time adjusting the Ghostty icon. I changed the app icon. This is how I spend my time being extremely productive.

🐢 Weird. The Option as alt key setting is fine.

🐇 Actually, the Alt key works; the reason we cannot make panes larger is that Alt-Right and Alt-Left are not bound to this.

🐢 You may be right, yes. Then, what’s the key to enlarge a pane?

🦊 List all the keys. Check the keys. You should have done this already.

🐇 resize-pane has keys, but they conflict with C-Right, etc., which are macOS display selection keys. I defined M-S-Right, etc., to resize and M-C-Right, etc., to swap the panes. Defining new keys with M-S…

bind-key -n "M-S-Right" resize-pane -R 10
bind-key -n "M-S-Left" resize-pane -L 10
bind-key -n "M-S-Up" resize-pane -U 10
bind-key -n "M-S-Down" resize-pane -D 10

🐢 We can set keys to swap windows too, maybe to M-C-PageDown, etc. M-PageDown now moves between windows.

🐇 Let’s take a look at the command options:

     swap-window [-d] [-s src-window] [-t dst-window]
                   (alias: swapw)
             This is similar to link-window, except the source and destination windows are swapped.  It is an error if no window exists at src-window.  If -d is given, the new window
             does not become the current window.

             If -s is omitted and a marked pane is present (see select-pane -m), the window containing the marked pane is used rather than the current window.

🐢 The use case will be limited, though.

🐇 Umm, right. Let’s stop procrastinating here.

🐢 It was productive procrastination, though. Now I can resize my tmux panes.

This script merges all windows from all Tmux sessions into a single session. You must specify the target session as a parameter. If you save the script as merge-tmux-sessions.zsh, you can run it like:

merge-tmux-sessions.zsh my-current-session

It will then move all windows into the session you specify.

#!/bin/zsh

# set -vuex
#
#  Specify the target session

target_session=$1

# Get the list of all sessions

sessions=$(tmux list-sessions -F '#S')

# Iterate through each session

for session in ${(@f)sessions}; do
    if [ "$session" != "$target_session" ]; then
        # Get the list of windows in the current session
        windows=$(tmux list-windows -t $session -F '#I')

        # Move each window to the target session
        for window in ${(@f)windows}; do
            tmux move-window -s ${session}:${window} -t ${target_session}
        done
    fi

vim.keymap.set({ "n", "i" }, "<F2>", '<esc><esc>yy:r!<c-r>"')

I type a command, like ls, on a line and hit <F2>. That line is copied, executed, and the output is read into the buffer just below it.

I use it for all sorts of tasks, from listing open PRs with gh to fetching website text with w3m. It has significantly improved my workflow, allowing me to use the shell effectively within textual notebooks.

bind-key -n S-F12 split-window -h -c "#{pane_current_path}" "gt c"

I just hit Shift-F12, and it opens a new pane in the current directory and runs the command.

In March, I realized that I had lost my enthusiasm for my work. It’s mainly a writing job. I noticed I was forcing myself to work. Normally, this shouldn’t happen. I like writing, I like the team, and I like my colleagues, so what was happening? I asked for a sabbatical to start in July. Now, I think it was a case of burning out. I was becoming alienated from the job, and it was depleting my willpower. I usually avoid work that requires me to spend my willpower over a long period.

I’ve begun to think that burnout is something similar to what Marx called alienation. Software development (or technical writing) is mostly a mental job. Your motivation and your talents should align. Otherwise, it becomes a chore, and you have to spend more and more willpower. Willpower, as recent studies show, is a finite resource. So, spending it on something for a long period probably causes burnout.

So, why does alienation happen in our line of work? It’s probably the same story as in less mental, more menial jobs. One has to feel that they are building a cathedral instead of just building a wall. If you believe that you’re building a cathedral, even if you work much longer, your enthusiasm rarely wanes. If you believe you’re just doing what your superiors ask, it shadows the vision that leads to enthusiasm.

Burnout is a natural defense mechanism for the second type of work. People need meaning in their lives more than anything else. We can suppress our emotions for some time to achieve material benefits. But if we can’t find meaning in the endeavor and just postpone that meaning to an indefinite future, it leaks. And eventually, it breaks.

This is probably why lower-level employees experience burnout more than those at higher levels. At higher levels, you need a vision—albeit sometimes a superficial one—to manage people. At lower levels, this is often less possible.

To avoid burnout, we need more meaning in our work. If you can’t find meaning in your work, at least try to find some outside of it.

Add the following to your .tmux.conf:

set-hook -g window-unlinked 'last-window'

There is a common delusion that if people are busy working, they are contributing. However, true contribution often stems from taking calculated risks.

Why should they take the risk? It is often more rational for employees to focus on small, low-stakes tasks than to take on challenges that push boundaries. Why should they bother improving software performance, for example, when the most frequent requests they receive are related to minor UI changes? The former carries a higher risk of failure and is technically more demanding, while the latter is easier to achieve and often more visible, making it seem more rewarding.

I’ve started using aerc as my command-line email client. Initially, I used its archived GitHub repository, but I found the software to be buggy. Switching to the active repository provided me with the fastest IMAP client I’ve ever used. Its asynchronous operations make the workflow incredibly smooth, as you don’t have to wait for the server after deleting or archiving each email.

goneovim

I’ve also begun using a Neovim GUI called goneovim. I previously used Neovim-GTK, but encountered issues—possibly due to Fira Code’s ligatures or other incompatibilities—that resulted in poor visuals and noticeable lag. I’m giving this new GUI a try, and so far, Fira Code and its ligatures are working perfectly.

Software written in Go is occupying more mindshare than I previously anticipated. Alongside Hugo, the Miniflux self-hosted RSS client, and the Mouthful comment server, these tools demonstrate that Go has truly taken off for system and performance-related tasks.

It looks a bit heavy for a CLI calculator, as it is written in Haskell and downloads 100+ MB of libraries, but when you need ASCII art to display your calculations or want to use spaces in variable names, it may prove useful.

• I began to use Intention to limit my Twitter time. It allows you to set a limited time (1, 5, 10, or 15 minutes) for yourself and tracks the total time you spend on addictive sites. When this total time is lower than your goal for a period, you get a streak. It looks visually and psychologically nicer than LeechBlock.

• I read the git reset section in the Git book. It details how git reset behaves with its --soft, --mixed, and --hard parameters. The first resets only the HEAD; the second resets both the index and HEAD; and the third resets the working tree and copies files back from the current HEAD to the working tree.

  One important point: Contrasting git checkout master and git reset master: the first moves HEAD to the master branch, while the second moves the current branch to master.

  git reset can also be used to squash commits. Basically, you git reset --mixed to an earlier commit like HEAD~3 and recommit. This creates a new commit, taking HEAD~3 as the parent and skipping HEAD~2 and HEAD~1, resulting in a new HEAD.

• Here are many useful pure Bash functions to be used in scripts. I’m a Zsh person, but writing Bash scripts is more portable, of course.

I have a shell script to add daily recurring tasks, such as “Drink Water” or “Pray Maghreb,” to this file. SimpleTasks expects the file to be at $HOME/Dropbox/todo/todo.txt, and I use a template file, such as template.txt, to populate it. However, as anyone who has used TODO files knows, there are always unfinished tasks; for instance, I don’t always drink my daily allotted amount of water.

So, my evening script moves completed tasks (marked as DONE) to their own file, removes recurring tasks from todo.txt, and repopulates them for a new day. (Note: The code below is not usable as-is; you must define the TODO, DONE, and TEMPLATE file paths correctly.)

TODO=.../todo.txt
DONE=.../$(date +%F)-done.txt
TEMPLATE=.../template.txt

#Move Done to $DONE
grep -wE '^x ' $TODO >> $DONE
sed -i '/^x /d' $TODO

#Delete lines with @Evening, @Morning or @Regular tags from todo
sed -i "/\b\(@Morning|@Evening|@Regular\)\b/d" $TODO
cat $TODO_TEMPLATE >> $TODO

I have configured cron to run this every day at 6 PM. (My “evening” starts earlier than my morning.)
