A quick "how to" on what you need to do to both setup AND recover a single-server PostgreSQL database using WAL-E

WAL-E: https://github.com/wal-e/wal-e
Assuming Ubuntu 12.04 LTS ("Precise")
We'll be using S3. Make sure you have an IAM in a group with GetObject, ListBucket and PutObject on the bucket you want to use (and that it's not public).

Setup:

These packages:

become active record migration expert (Rails 4.0.2)

workflow:

create model

$ rails g model NameOfModel
    invoke  active_record
    create    db/migrate/YYYYMMDDHHMMSS_create_name_of_models.rb

a simple git branching model

This is a very simple git workflow. It (and variants) is in use by many people. I settled on it after using it very effectively at Athena. GitHub does something similar; Zach Holman mentioned it in this talk.

Tutorial: Meteor in Windows using Vagrant

BEFORE YOU CONTINUE:

Now, Meteor runs in any Windows without any line of this tutorial. Just download the Meteor binary! Yay!!
mrt is no longer used with Meteor 1.0

These days some people were discussing at meteor-talk group about running Meteor at Windows and I’ve recommended them using Vagrant. It’s a very developer-friendly piece of software that creates a virtual machine (VM) which let you run any operating system wanted and connect to it without big efforts of configuration (just make the initial installation and you have it working).

Many packages (I've tested) for running Meteor+Vagrant fails because Meteor writes its mongodb file and also other files inside local build folder into a shared folder between the Windows host and the Linux guest, and it simply does not work. So I've put my brain to work and found a solution: do symlinks inside the VM (but do not use ln. Use mount so git can follow it). It’s covered on
