These scripts are used for simple management of hostnames for several VirtualBox VMs comprising a test or sandbox environment on your local machine.

Architecture:

1. each VM is configured to use bridged network adapter, so all VMs and the host can see each other

2. a script is installed in each VM to run on post-ifup, which grabs VM's IP, puts "$IP $desired-hostname $desired-fully-qualified-hostname" into /etc/hosts, changes hostname correspondingly, and puts VM's hostname and fq-hostname into VM's properties

3. a script is used on the host machine, which loops through running VMs, and updates /etc/hosts on the host machine and on the VMs

Fibur

Fibur is a library that allows concurrency during Ruby I/O operations without needing to make use of callback systems. Traditionally in Ruby, to achieve concurrency during blocking I/O operations, programmers would make use of Fibers and callbacks. Fibur eliminates the need for wrapping your I/O calls with Fibers and a callback. It allows you to write your blocking I/O calls the way you normally would, and still have concurrent execution during those I/O calls.

Example

Say you have a method that fetches data from a network resource:

ryanb

$('#products').append('<%= j render(@products) %>');
<% if @products.next_page %>
  $('.pagination').replaceWith('<%= j will_paginate(@products) %>');
<% else %>
  $('.pagination').remove();
<% end %>

Since Obie Fernandez posted his demands as a consultant I thought I would post mine too.

• I will be paid $10,000 per day, in $50 bills, in a titanium briefcase that you will purchase for the sole purpose of providing a container for my money. You may not re-use the briefcase for the next day's payment.
• The $50 bills must have been printed in the last three months and handled by no more than 2 people.
• Anybody handling the money must do so with clean white gloves that must be placed on the hand immediately before touching the briefcase. If the hand leaves the briefcase, the white gloves must be replaced with new ones before the briefcase is touched again.
• I will arrive in your city by a private jet. Fuel and any other costs incurred by this trip will be paid by you, and is not included in the $10k/day fee.
• Transportation from my jet to your workplace must be performed by a driver who is between the ages of 50
