~/.lftp.rc parameters detailed
########## SETTINGS
# On startup, lftp executes ~/.lftprc and ~/.lftp/rc. You can place aliases and 'set' commands
# there. Some people prefer to see full protocol debug, use 'debug' to turn the debug on.
# Certain commands and settings take a time interval parameter. It has the format Nx[Nx...], where N is time amount
# (floating point) and x is time unit: d - days, h - hours, m - minutes, s - seconds. Default unit is second. E.g.
# 5h30m or 5.5h. Also the interval can be 'infinity', 'inf', 'never', 'forever' - it means infinite interval. E.g.
# 'sleep forever' or 'set dns:cache-expire never'.

Checkout github pull requests locally

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = git@github.com:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

Vagrant tutorial

Vagrant Setup

This tutorial guides you through creating your first Vagrant project.

We start with a generic Ubuntu VM, and use the Chef provisioning tool to:

  • install packages for vim, git
  • create user accounts, as specified in included JSON config files
  • install specified user dotfiles (.bashrc, .vimrc, etc) from a git repository

Afterwards, we'll see how easy it is to package our newly provisioned VM

Documentation-Driven Development (DDD)

Documentation-Driven Development

The philosophy behind Documentation-Driven Development is a simple: from the perspective of a user, if a feature is not documented, then it doesn't exist, and if a feature is documented incorrectly, then it's broken.

  • Document the feature first. Figure out how you're going to describe the feature to users; if it's not documented, it doesn't exist. Documentation is the best way to define a feature in a user's eyes.
  • Whenever possible, documentation should be reviewed by users (community or Spark Elite) before any development begins.
  • Once documentation has been written, development should commence, and test-driven development is preferred.
  • Unit tests should be written that test the features as described by the documentation. If the functionality ever comes out of alignment with the documentation, tests should fail.
  • When a feature is being modified, it should be modified documentation-first.
  • When documentation is modified, so should be the tests.
