2008 Giro di Peninsula



On Saturday I completed the 2008 Giro di Peninsula. I chose the 35k (22 miles) route which took us up to Crystal Springs Resevoir. After the ride, we had a pasta lunch and then rode 25 miles home from San Mateo to Mountain View along Alameda de Las Pulgas. All told, the ride clocked in at just under 50 miles.

After the ride, we went to Village Pub to celebrate.

I did the same ride last year, check out that shot:

Spacewalk




I'm sitting in the Pittsburgh airport waiting for some friends to arrive from Chicago. As I peruse the RSS feeds on Google Reader I come a cross a post by Matt Assay confirming the open source release of Red Hat Network, codename Spacewalk.

I've been a RHN customer for most of my professional career. I helped bring Satellite Server, Red Hat's flagship system management platform to my past employer where we leveraged the software to great success.

At my new gig, we are running an open source derivative distro of Red Hat called CentOS. One of the major features lacking with this approach has been the abillity to manage updates and patches for a large number of distributed systems. Spacewalk fills that void.

I'm excited to start playing with this new software and using it to better maintain our existing infrastructure. I was also pleasantly surprised to see a related project, cobbler, mentioned as the first integration point in Red Hat's rollout of the new platform. We've been using cobbler to manage our system deployments for the past year or so and I'm active on the mailing list for that project. When two software projects dovetail together so nicely, it makes the job of any architect much easier.

Hat's off to Red Hat for finally getting around to releasing Spacewalk in open source. I have some work to do, but it will be both fun and familiar.

Here come my boys, gotta go.

Tour de Cure Pre Ride Report

Thanks to all my friends and family who have generously donated to the American Diabetes Association Tour de Cure. The ride is tomorrow morning and I'm happy to report that we've raised over $500 this week to help find a cure for Diabetes!

Today, we did a training ride of just over 10 miles to get prepped. My legs feel good and ready to tackle Alpine Road tomorrow on the climb.

I'll put up a photo of my ride as soon as I get it.

There is still time to donate! If you would be so kind, please follow this link to my Tour de Cure Page. Your donation will go directly to the ADA and will help find a cure to this deadly disease.

You may continue to make contributions up to one month after the ride.

Thanks!

New Tires and Tubes


I decided to upgrade my bike by adding new tires. The bike came stock with cyclocross tires which are 35 mm in width and have quite a tread on them. To replace the stock tires, I chose Schwalbe Stelvio tires which are just 23 mm in width and with no tread.

To accommodate the slimmer tires, I also upgraded the inner tubes. For tubes, I chose Qtubes 700cx18-23 mm with a 48mm presta valve.

A quick test ride up the block and back revealed what you might suspect, the bike is faster! This is good news for me as I've been riding with the clunker tires since I got the bike. I'll take a longer ride on Saturday or perhaps Friday and see what my average speeds look like before and after the switch.

Sequoia Century 50k in the Bag

Sunday I rode the Sequoia Century 50k ride. I started around 10 AM from the VA in Palo Alto and finished there at around 12:45. It was a fairly easy ride with just one climb up to the Alpine Rd/Portola Rd intersection. From there, a nice descent to Redwood City and then back through residential streets to the start.

Next week: Tour de Cure!
