Here are a few fun shots from our snowshoeing trip last weekend at Bear Lake in Rocky Mountain National Park.  We also enjoyed some sledding at Hidden Valley.  
One of the things that’s come out of the proposed “Refresh quota usages” spec are the little-known nova max_age and until_refresh quota settings.  These options allow you to trigger quota refreshes within Nova at different intervals. This can help with the various quota bugs, where occasionally the quota usages can get out of sync with […]
Key Takeaway – We Need Operators’ Feedback! A common thread throughout the entire meetup is operators providing feedback and comments on specs and reviews.  It’s clear this feedback is invaluable to the developer community.  It also provides benefit to the operators community as our feedback helps shape the priorities of the various projects. I think the […]
Here are some of my notes and main take-aways from the OpenStack Operators meet up going on today and tomorrow in Philadelphia.  (Obviously there is a lot more data and details in the individual etherpads.) The meeting was originally scheduled to take place at the Comcast Center, but was moved to The Hub at United […]

Note: I did a talk at the OpenStack Liberty Summit in Vancouver based on this post.  The slides are available on Slideshare, as well as a video recording of the session. (See the Exploring OpenStack Nova Cells post for an introduction and background information about Nova cells.) If you already have a Nova instance configured with […]
Cells Overview Nova cells was introduced at the Folsom/Grizzly timeframe as a way to scale Nova beyond the limitations of a single database backend and message queueing system.  This was mainly geared at larger operators who needed to scale beyond hundreds of hypervisors. At a basic level, Nova cells creates a hierarchy of Nova installs, each […]
Lately I’ve been trying to get the RabbitMQ management plugin to listen on more than one port.  This is in an effort to resolve these comments on the puppetlabs-rabbitmq Puppet module.  I want one listener on localhost only, in non-SSL mode, and a second listener on a different port which serves SSL requests from external […]
Random notes I took during the OpenStack Paris Summit.  May or may not be useful for others. Note:  Matt Fischer has a great post on Key Learnings from Paris.  Also featured on the OpenStack Superuser site!

Today I fulfilled my dream of hiking to the bottom of the Grand Canyon! Click any image for a slideshow view of all the pictures. GPS tracks in Google Earth. Google Maps link.
Best wishes from our family this Christmas season! 2010 was a year of many changes for us. Early on, we found out that Adena was pregnant with our third baby (a boy.)  Born on October 7, Jace Stewart was about a week past his due date.  Official stats: 8 lbs. 9 oz., 21 ¼ inches, 6:39pm. […]
Today’s outing was a hike up Mt. Democrat and Mt. Cameron with a couple friends.  The plan was to follow the Democrat/Cameron/Lincoln/Bross combo route around as far as we felt like. Met up at the US-285 and Twin Forks park-and-ride at about five minutes after five A.M. and then took one car on to the […]
During the first week of August, my family and I were visiting my wife’s family in rural Antler, North Dakota.  It’s become an August tradition for us to go back for a couple weeks in August to help with the harvest.  My father-in-law raises wheat, canola, peas, and sunflowers.  The first three of those crops […]
While visiting my in-laws last week, I took a day trip down to the Garrison Dam for a tour of the hydroelectric power plant.  I wasn’t sure how much I’d really get to see, not knowing the security stance of those type of places these days.  However, I was pleasantly surprised.  Not only did we […]
Thursday and Friday this week we went out and used our day of skiing at Copper Mountain. It turned out to be a good time to go, as there was several inches of new snow earlier in the week as well as on the days we skied. Temperatures were much lower than during our trip […]
This week most of Colorado was blanketed with several inches of spring snow. Here in Castle Rock we got about twelve inches, which is the most snow we’ve gotten from one storm since Thanksgiving. Copper Mountain received two feet, which is great because we are skiing there next week. We’ve had an unusually dry winter […]
PBS’s FRONTLINE tonight was an interesting look at the Federal debt during this time of a faltering economy and the affect that the Government’s entitlement programs (Social Security, Medicare, Medicaid) have on it.  Currently those programs comprise roughly 40% of the Federal budget, and are projected to consume over 20% of GDP by the time […]
A couple weeks ago we went on our traditional spring skiing trip. Grandma usually comes out for a few days sometime around my birthday, and we take that opportunity to go ski since we can just leave the kids with her. Normally we just go to one location and ski just for one day. This […]
