Postgres Cheatsheet

This is a collection of the most common commands I run while administering Postgres databases. The variables shown between the open and closed tags, "<" and ">", should be replaced with a name you choose. Postgres has multiple shortcut functions, starting with a forward slash, "". Any SQL command that is not a shortcut, must end with a semicolon, ";". You can use the keyboard UP and DOWN keys to scroll the history of previous commands you've run.

Setup

installation, Ubuntu

#' ## Storing R Objects in a SQLite Database

#' Two packages we are using. The first is the ```RSQLite``` which will be used to create and manage an in-memory SQLite database. The second is ```igraph``` which I will use to create and visualize a random network. Some of the work I do is on network simulation. I often don't know the metrics I need from a simulated network when it's created, so I want to be able to store the networks that are created so that I can go back later and analyze them.
library(RSQLite)
library(igraph)

#' Create a database in memory.
con <- dbConnect(SQLite(), ":memory:")

#' The table has two columns, an *id* column and a column called *graph* which is a **blob** type. This type just stores binary data.

Overview

This is a bash script that will automatically turn your wifi off if you connect your computer to an ethernet connection and turn wifi back on when you unplug your ethernet cable/adapter. If you decide to turn wifi on for whatever reason, it will remember that choice. This was improvised from this mac hint to work with Yosemite, and without hard-coding the adapter names. It's supposed to support growl, but I didn't check that part. I did, however, add OSX notification center support. Feel free to fork and fix any issues you encounter.

Most the credit for these changes go to Dave Holland.

Requirements

• Mac OSX 10+
• Administrator privileges

/**
 * This is a very simple example of an ember component to integrate
 * nnick/chart.js in an ember.js application. Basically, it is simply
 * using the components hook to create a ChartJS canvas element.
 * Additionally, it supports an update property that allows you to
 * let the chart re-rendet if your data or options change. Chart.js
 * doesn't support updating its data so this will just create a new
 * chart on the given canvas.
 * 
 * Example usage in a handlebars template:

- Check rails version
$ rails -v

- To update rails
$ gem update rails

- Creating a new rails app using postgresql
$ mkdir rails_projects
$ cd rails_projects
$ rails new myapp --database=postgresql
