Random idea

I'm a big fan of the Ops School idea. I've struggled for years about how to "train up" someone coming into this field. So much of our skill set is forged in the fire of outages and troubleshooting.

One of the things that is both good and bad about system administration and operations is that we tend to see patterns. It's good in that we immediately see things that stand out. The downside is we tend to superimpose that pattern recognition in inappropriate ways.

We had an interesting issue happen yesterday at the dayjob. I won't go into exactly what it was here but I had an idea based on some graphs I was looking at. It's part social experiment but it's also part problem solving skills.

Given the following image with no context, what do you think happened? What are some of the key indicator points that jump out and what pattern do they call to mind?

If you have ruby-1.9.2, good. I used rvm, and did a recent install with

rvm install ruby-1.9.2
rvm --default use 1.9.2

Then to the SproutCore parts:

gem install sproutcore                         [The console output indicated SproutCore 1.6]

cd to your dev area, e.g. .../Development/sproutcore
