That's a 72 Norton Commando fashioned into a cafe racer. Heavy.com named a newer version the #1 bike in the 2012 New York International Motorcycle Show. (I didn't like Heavy.com's picture, so I found a better one from the blog listed as source, above.)

OTN also has an annual top 10. In that post by Bob Rhubart, from OTN's Architect community, six of the top ten technical articles were about technologies of interest to system admins and developers.

Would You Swim Laps in Lake Baikal?

This is the lake where Yuli Vasiliev's countrymen swim laps.

Yuli is one of my favorite OTN writers not just because he really knows his stuff. Not just because his writing is clear and accurate. And not just because his English is better than the English of most native speakers. Yo, those are all good reasons. But it's the Lake Baikal thing.

Yuli recently wrote two wicked good how-to's about Oracle VM Templates. You should read them. You might gain a gram of Yuli's respect. Two grams, if you can head butt icebergs while you swim.

How to Use Oracle VM Templates

How to prepare an Oracle VM environment to use Oracle VM Templates, how to obtain a template, and how to deploy the template to your Oracle VM environment. Also how to create a virtual machine based on that template and how you can clone the template and change the clone's configuration.

How to Use Oracle VM VirtualBox Templates

How to use Oracle VM VirtualBox Templates in Oracle VM VirtualBox. Similar to the article above, but it describes how to download, install, and configure the templates within Oracle VM VirtualBox, instead of on bare metal.
