Static ip on a VMWare Fusion Virtual Machine

Shamelessly copied from: http://www.stereoplex.com/blog/vmware-fusion-guests-with-a-static-ip VMWare Fusion v4

get the MAC address of the vm: Virtual Machine - Settings - Network Adapter - Advanced make a note of it, it will be needed later

open /Library/Preferences/VMWare Fusion/vmnet8/dhcpd.conf: make note of the subnet range -> select a fixed ip outside of this range make note of the "options routers" ip address -> needed later append:

Postgresql 9.1 server on CentOS 6

install CentOS 6

yum update
yum upgrade

check the server time. sync the time to a time server if needed (service 'ntpd')

download and install Postgresql Server v9.1 rpm package:

rpm -Uvh http://yum.pgrpms.org/9.1/redhat/rhel-6-x86_64/pgdg-centos91-9.1-4.noarch.rpm

This should have installed the necessary server package: postgresql91-server.x86_64.

Switching between ActiveRecord and DataMapper - the gory details (https://github.com/datamapper/datamapper.github.com.git)

DM's Integrity Map causes issues when setting up tables in legacy repositories. The rails console can access the models, but the controller cannot. The (temporary?) solution is to add the following lines to the models. http://groups.google.com/group/datamapper/browse_thread/thread/16dc095f33097050#

def self.default_repository_name
  :your_repository
end
def self.repository(name = nil, &block) 
  super(:your_repository, &block)
