set up my new mac laptop

I am starting my first day at Harvard FAS informatics and I will keep a note here on how I set up my new laptop.

customize terminal

following this gist:

download iterm2 for mac here.

install on-my-zsh

sh -c "$(curl -fsSL"

You will have to install git first for the upper command to work. Now, when you fire up your terminal, it looks much more prettier! (there are many other schemes for oh my zsh, I found the default is good. You can change it by modifying the .zshrc file in your home directory.)

Selecting a Theme

Once you find a theme that you’d like to use, you will need to edit the ~/.zshrc file. You’ll see an environment variable (all caps) in there that looks like:

ZSH_THEME="robbyrussell" To use a different theme, simply change the value to match the name of your desired theme. For example:

ZSH_THEME="agnoster" # (this is one of the fancy ones) see

install conda

install conda, go to and download the graphic installer. It is ~600 MB and take some time.

Usually conda is installed in the home directory. Somehow, it was installed in the / root.

add the following to the ~/.zshrc file

put conda after the $PATH, otherwise somehow oh-my-zsh will not work properly (the folders are not displayed with color etc)

export PATH=$PATH:"/anaconda3/bin"

file editor

sublime or Atom

download sublime from and install it.

if you want to open sublime in terminal

open /Applications/Sublime\

# make a symbolic link for it
ln -s "/Applications/Sublime" /usr/local/bin/sublime

# now you can
sublime my.txt

install R and Rstudio

The current R version is R3.5.1. Download it from here.

Install Rstudio v1.2.1013-1. I installed the preview version of Rstudio because it can evalute python code directly throught reticulate. I’ve used pycharm before, but it is too clunky for me. One can of course set up both R and python inside sublime or Atom, but I do not want to leave Rstudio :)

install docker


install slack

Slack For team communication

install Notion

Notion For to-do list
