It took me several re-stacks, but I finally got a working devstack with Ironic and Heat services running. I mostly followed directions here, but I ended up making a few changes in the local.conf file. Start with cloning the repo and creating the stack user: $ git clone https://github.com/openstack-dev/devstack.git devstack $ sudo ./devstack/tools/create-stack-user.sh Now, switch [...]

I was very fortunate to win a 3D printer, Makerbot Mini, at a developer conference. I think 3D printing technology is amazing, but never had a really good excuse to purchase one. Now, I don’t need excuses! Here are my first impressions: If you have a 3D printer at your desk at work, people will [...]

OpenStack services have very powerful command line interfaces, with lots of different options.  I went looking for a good command line cheat sheet, and did not find many options, so decided to created one myself.

So far, it has been tested with the WMware Fusion, and is somewhat of a work in progress. Keep in mind, that it takes a [...]
