##Setup - Installing Pip, Python and Django
In order to get started with Django you will need to install it on your Mac globally. First, we need to check to see which version of python we have installed like this:
python --version
Your output should look something like this:
Python 2.7.10
| #!/bin/bash | |
| NOWDATE=`date +%Y-%m-%d` | |
| BACKUPNAME="$NOWDATE.sql.gz" | |
| echo "Creating backup of database finances to $BACKUPNAME" | |
| mysqldump --user=[username] --password=[password] [database] | gzip -9 > $BACKUPNAME | |
| echo "Succesfully created database backup" | |
| echo "Uploading backup to Amazon S3 bucket…" |
I've been doing some work lately with JSON documents in PostgreSQL using jsonb columns. You can query these documents
using a GIN index in PG, but the syntax can be a little cumbersome
SELECT "events".* FROM "events" WHERE "events"."body" @> '{"shift":{"user_id":2}}'You have to construct the right side of the query as a JSON string, which is a bit annoying. So I wondered if I could adapt Arel to do the tedious stuff for me.

At Crush + Lovely, we use Railsmachine's Moonshine to automate the configuration of our servers. When writing our deployment recipes, VMWare Fusion's ability to take snapshots and rollback to these snapshots is a huge timesaver because it takes just seconds to roll a server image to it's original state.
When you're just configuring a single server, having a static IP address for your server image isn't too important, but when you're configuring multi-server setups, it can be useful to duplicate a number of server images and give each a static IP address so you can consistently deploy to them. While not documented well at all, it turns out that this is relatively easy to accomplish in four simple steps.
Let's say you have a guest machine with the name ubuntu-lucid-lynx-base
