My Setup

This is a list of how I go about setting up a new computer. I did have a script and a repo of dotfiles, but I find this difficult to maintain as config etc develops across several computers. Also the most useful parts are difficult to share in isolation from other ‘moving parts’ of the setup.

Ubuntu

Although I started my career with over 12 flavours of unix, and more recently I’ve used CentOS, Arch, Debian… I’ve settled on Ubuntu for simplicity and for ease of compatibility.

Most of my machines run the latest LTS version.

NOTE: If every owning a chromebook, with crouton using these instructions

Immeadiately after installation

Use the SSO prompt you are presented with and sign in to:

Ubuntu One
Microsoft
Google

Stuff that if not done will annoy you:

Open Firefox and login to get Bookmarks
Open Settings and set mouse to natural scroll
Run sudo apt-get install gnome-tweaks -y && gnome-tweaks
Then go to “Keyboard and mouse” -> Additional Layout -> Caps Lock -> Make Caps an addtional Esc

Visit https://blog.diversemix.com/software/setup.html and follow instructions from there

Essential To Start

The following sections setup git does assume you have pulled by dotfiles with:

# Add user to sudoers without password
echo "peter ALL=(ALL) NOPASSWD: ALL" > /etc/sudoers.d/peter

# Bare essentials
sudo apt install -y \
build-essential net-tools nodejs npm vim-athena git

# Generate a private key
ssh-keygen -t ed25519 -C "your_email@example.com"
cat cat ~/.ssh/id_ed25519.pub

Now you can browse to https://github.com/settings/keys and add the key in there.

# Clone dotfiles
cd ~
git config --global user.name "diversemix"
git config --global user.email diversemix@gmail.com
git config --global diff.tool meld
git config --global difftool.prompt false

git clone git@github.com:diversemix/dotfiles.git
git clone git@github.com:diversemix/diversemix.github.io.git
cd diversemix.github.io
vim software/setup.md

Essential Apps

Useful apps I like to have installed:

# Useful
sudo apt install -y \
ack \
bat \
diodon \
figlet \
fzf \
gimp \
imagemagick \
jq \
keepassx \
lolcat \
make \
meld \
nodejs \
npm \
openssh-client \
openssl \
postgresql-client-common  \
postgresql-client \
ranger \
silversearcher-ag \
tcpdump \
tmux \
w3m \

After doing the above, the individual apps may need some setting up….

bat - ``` mkdir -p ~/.local/bin ln -s /usr/bin/batcat ~/.local/bin/bat

- fzf

### Alternative Windowing Systems

sudo apt install -y xubuntu-desktop xfce4 sudo apt install -y i3 zathura

### Bash Aliases

- Link with `ln -s ${HOME}/dotfiles/diversemix_aliases ~/.bash_aliases`

(If you already have this file you can source `diversemix_aliases` at the end)

### Bash Environment

There are 2 steps:

1) Edit `.bashrc` and add `source ~/dotfiles/diversemix_profile`, you may wish to follow the pattern below 
so that you don't have issues in non-interactive shells.

case “$-“ in i) source ~/dotfiles/diversemix_profile ;; *) echo This shell is not interactive ;; esac

### Configure ranger 

PDF previews by uncommenting the `application/pdf`section, after:

ranger –copy-config=scope vim ~/.config/ranger/scope.sh


Image previews with

pip3 install ueberzug set preview_images true » ~/.config/ranger/rc.conf set preview_images_method ueberzug » ~/.config/ranger/rc.conf

### ViM Environment

First install `vim-plug`

curl -fLo ~/.vim/autoload/plug.vim –create-dirs
https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim

Link the rc file with: `ln -s ${HOME}/dotfiles/diversemix.vimrc ~/.vimrc`

Don't forget to now run `:PlugInstall` from within `vim`

* TODO - installing `coc` and `coc-explorer`

### TMux Environment

Link the conf file with: `ln -s ${HOME}/dotfiles/diversemix.tmux.conf ~/.tmux.conf`

### Dropbox

Go to the [dropbox install page](https://www.dropbox.com/install) and install from the first
link 
[using the  deb file](https://www.dropbox.com/download?dl=packages/ubuntu/dropbox_2020.03.04_amd64.deb)

### Using font Source Code Pro

Install the patched fonts by cloning repo and running the install:

git clone git@github.com:powerline/fonts.git cd fonts ./install.sh

Now go to Terminal -> Preferences and change the font to `Source Code Pro for Powerline`

### Installing bat

mkdir -p ~/.local/bin ln -s /usr/bin/batcat ~/.local/bin/bat

### Setting up FZF

Documentation can be [found here](https://github.com/junegunn/fzf)

Setup I use in my .bashrc:

export FZF_CTRL_T_COMMAND=’rg –files –follow –no-ignore-vcs –hidden -g “!{node_modules/,.git/,*/.class}”’ export FZF_CTRL_T_OPTS=’–border –info=inline –preview “bat –style=numbers –color=always –line-range :500 {}” –bind shift-up:preview-page-up,shift-down:preview-page-down’


### Webcam

sudo apt install guvcview ```
