Starting at the beginning:

Let's just assume you're using an Ubuntu-ish distro of Linux. In some ways that makes this a little more complicated, but on the other hand, it lets me assume you have experience with other package managers. So the big thing here is that conda is it's own little scientific apt-get (python packages, GIS tools, R + R packages, gcc, etc) that goes off and builds sandboxes contained in individual rooms. Then there's pip. Pip is specifically for python packages only and in my opinion, should only be used when the conda package isn't available.

Back to conda: conda is a package manager that depends on python, but is not per se an installation of python. So:

JavaScript function hoisting by example

Below are many examples of function hoisting behavior in JavaScript. Ones marked as works successfuly print 'hi!' without errors.

To play around with these examples (recommended) clone them with git and execute them with e.g. node a.js

Notes on hoisting

(I may be using incorrect terms below, please forgive me)

NOTE: This is a question I found on StackOverflow which I’ve archived here, because the answer is so effing phenomenal.

Q: How can I make a chain of function decorators in Python?

If you are not into long explanations, see [Paolo Bergantino’s answer][2].

PSQL Cheatsheet

Magic words:

psql -U postgres

Some 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)
