!!! WARNING !!! Be careful with opening the profile folder in FF, it always opens a wrong one. I've spend on hour before found the proper folder. Good folder: /home/saw/snap/firefox/common/.mozilla/firefox/n26fpmvd.bloomreach !!! WARNING !!!

Create a file named chrome/userChrome.css in your profile directory:

mkdir chrome && touch chrome/userChrome.css

Populate the following css code:

#main-window[tabsintitlebar="true"]:not([extradragspace="true"]) #TabsToolbar > .toolbar-items {
  opacity: 0;
  pointer-events: none;
}
#main-window:not([tabsintitlebar="true"]) #TabsToolbar {
    visibility: collapse !important;
}
#sidebar-box[sidebarcommand="treestyletab_piro_sakura_ne_jp-sidebar-action"] #sidebar-header {
  display: none;
}
.tab {
  margin-left: 1px;
  margin-right: 1px;
}

Then go to about:config in your address bar and set this to true:

toolkit.legacyUserProfileCustomizations.stylesheets

Damn, this thing is the single biggest improvement ever.

sudo echo "MOZ_USE_XINPUT2=1" >> /etc/environment
sudo reboot

My goodness, touchpad scrolling in FF is so precise and smooth now!

To make scrolling smooth for the mouse wheel, change the following in the about:config:

general.smoothScroll.mouseWheel.durationMaxMS	1000
general.smoothScroll.mouseWheel.durationMinMS	200
mousewheel.acceleration.start	1
mousewheel.default.delta_multiplier_y	200
mousewheel.system_scroll_override.enabled	false

Update 7 Nov 2024: these settings interfere with touchpad scrolling. It becomes a bit jerky. For touchpad, the ideal value for mousewheel.default.delta_multiplier_y is 50.

Now the text does not jump, straining my eyes, when I scroll it with the mouse wheel.

This is the font I use for all my terminal and coding work.

1. Download and unpack the fonts
2. cd JetBrainMono-2.304/fonts (there should be folders: ttf, variable, webfonts)
3. sudo mv * /usr/local/share/fonts

The /usr/local/share/fonts is a better place to do it than the /usr/share/fonts, because the latter is the location where fonts from packages are installed to (or so they say). Tried setting JetBrains Mono in the gnome-tweak-tool system-wide, but for some reason it didn't render properly in the open editor, so maybe I'll do it later and then I need a system restart. The terminal look with JetBrain Mono: <insert screenshot>

Now, time to install dots

cd dots
stow alacritty git tmux
ln -s ~/dots/zsh/.zshrc ~/.zshrc

Move the contents of the old ~/.ssh to the new ~/.ssh

Install fzf by downloading a binary from github releases, copying it to /opt and linking in /usr/local/bin https://github.com/junegunn/fzf/releases

Download the deb file from the releases: https://github.com/BurntSushi/ripgrep/releases dpkg -i ...

Install aws-cli on Ubuntu:

sudo snap install aws=cli --channel=v2/stable --classic

Move the old aws configs to current home:

mv /home/saw-ub204/.aws .
mv /home/saw-ub204/.awscliv2 .

We still have not switched from this corporate closed software to something community-driven, thus again I have to add deb repos. Source https://docs.docker.com/engine/install/ubuntu/

Full krew instruction: https://krew.sigs.k8s.io/docs/user-guide/setup/install/ I just ran this and it somehow installed the krew plugin without any need for root privileges. No idea where does it install krew to.

(
  set -x; cd "$(mktemp -d)" &&
  OS="$(uname | tr '[:upper:]' '[:lower:]')" &&
  ARCH="$(uname -m | sed -e 's/x86_64/amd64/' -e 's/\(arm\)\(64\)\?.*/\1\2/' -e 's/aarch64$/arm64/')" &&
  KREW="krew-${OS}_${ARCH}" &&
  curl -fsSLO "https://github.com/kubernetes-sigs/krew/releases/latest/download/${KREW}.tar.gz" &&
  tar zxvf "${KREW}.tar.gz" &&
  ./"${KREW}" install krew
)

Install kind to create k8s clusters:

[ $(uname -m) = x86_64 ] && curl -Lo ./kind https://kind.sigs.k8s.io/dl/v0.24.0/kind-linux-amd64
chmod 555 kind
./kind --version
sudo mv ./kind /opt/kind-v0.24.0
sudo ln -s /opt/kind-v0.24.0 /usr/local/lib/kind

This is a nasty problem. After upgrading to Ubuntu 24.04 from 22.04 the colors in emacs in terminal were all wrong. Previously, emacs used the basic colors from the terminal, by basic I mean the first 16 colors in the palette - red, green, magenta, bright red etc. So in my terminal I defined red as #dc322f. Red in emacs used that as red. But after the upgrade, emacs' red was defined as #ff0000. I searched for ways to force emacs to respect the terminal colors, but the only thing I could find is everyone moving to 24-bit color support in emacs.

What I tried was to set font color to a precise hex value, say #dc322f. Emacs did not display that precise color, but instead picked something close to that.

I tried this in a couple of terminals - alacritty, gnome-terminal, konsole. And then I have noticed that this subsitution of the closest color happens only when I run emacs inside tmux! Aha! So this is not the terminal that screws my colors, this is tmux! Quick googling and now we have new lines in the .tmux.conf:

# Enable emacs to use 24-bit color support in the terminal
set -g default-terminal "xterm-256color"
set -ag terminal-overrides ",xterm-256color:RGB"

And running emacs in terminal as: COLORTERM=truecolor emacs -nw

Damn, now all colors can take precise 24-bit values.

In .zshrc fzf is called and it overrides a bunc of keys. Notably:

• C-R - search command history backwards
• M-C - like broot, will search for files in the current folder
• In the shell, type "$ emacs **<TAB>" - same as "$ emacs $(fzf)" - will fuzzy find files in the local directory and launch emacs
• "rg . | fzf" - fuzzy find in all files

Rebooting the machine usually helps. Otherwise I set the frequency from the command line:

sudo cpupower frequency-set -d 4.3Ghz

But then it jumps between 800Mhz and 4.3Ghz, without anything in-between.

I've installed Windows and as soon as it downloaded the latest drivers, this issue happened too, on Windows! I had to go to devices and revert the drivers back… My god, synaptics, what have you done…

Despite being half-year old, it is a disaster.
