Find large things with Linux
#ncdu is another utility that might be useful (and it's interactive)
#Find 10 largest files
find . -type f -print0 | xargs -0 du | sort -n | tail -10 | cut -f2 | xargs -I{} du -sh {}
#Find 10 largest directories (change f to d)

TODO: Rewrite this from scratch
TODO: Use this code as an example of how not to code:
- no comments
- nondescript var names
- inline html generation
- inline css generation
- not keeping a reference to DOM elements
- browser checks
- code quadruplication (I've never actually seen that before)

cx_Oracle installation instructions/notes for macOS or Linux

cx_Oracle Installation Instructions

I've had to put cx_Oracle (python Oracle database connector) on macOS and Linux, and both processes were similar but poorly documented on Oracle's website.

These instructions were written and tested using the client 12.1. The instructions for any 12.x are the same, but you may need to change 12_1 to 12_2 in commands if you are using version 12.2, etc.

Instructions

  1. Download 64 bit (easy to download 32 by mistake) basic + sdk instantclient from Oracle website (Note: you need an account, I used throwaway email)
