psql -U postgresSome interesting flags (to see all, use -h or --help depending on your psql version):
-E: will describe the underlaying queries of the \ commands (cool for learning!)-l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

| # This script will install a Git pre-push hook that prevents force pushing the master/main branch. | |
| # There are three variants that I have built: | |
| # - pre-push: prevents force-pushing to master/main. | |
| # - pre-push-2: prevents force-pushing to master/main depending on the remote (you need to edit the file!). | |
| # - pre-push-3: prevents any type of pushing to master/main. | |
| # Set the desired version like this before proceeding: | |
| # FILE=pre-push | |
| # Single repo installation: |

| # This script starts emacs daemon if it is not running, opens whatever file | |
| # you pass in and changes the focus to emacs. Without any arguments, it just | |
| # opens the current buffer or *scratch* if nothing else is open. The following | |
| # example will open ~/.bashrc | |

What I did to get Python 3.4.2 on Ubuntu 14.04. The stock version of Python 3 on Ubuntu is 3.4.0. Which is missing some of the best parts! (asyncio, etc). Luckily I discovered pyenv which solved my problem.
Pyenv (not to be confused with pyvenv) is the Python equivelant of rbenv. It lets you configure which Python environment/version is available per directory, user, or other session variables.
I followed the instructions here to install pyenv in my home directory. Verbatem, those instructions are:
sudo apt-get install git python-pip make build-essential libssl-dev zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev
