# Some interesting tidbits …

A server reliability report is out, comparing OSes and machines. Had a few surprises in it. They did note that Redhat and others had good uptime.

that email is a real email address, and yes, if a spammer sends to it, our spam filtering will get better …

Hmmm…. Last downtime was due to an errant yum run, which invoked OOM, and went all wild west on me. There are a few folks who think that OOM is safe, it isnt. Sort of like having an unpredictable uncle in the house, with weapons and a trigger. Don’t go past that trigger and all is well.
Then I also saw last week, the Collaboration summit kicked off, with some positively amazing data.

Also at the Summit today, IDC Vice President of Research, Al Gillen, will present a new IDC White Paper titled The Role of Linux Servers in Commercial Workloads. The white paper, sponsored by The Linux Foundation, outlines the state of the Linux server market and considers the increasing shift in Linux deployments from infrastructure-oriented workloads to mainstream business-oriented workloads. It predicts significant growth and strong long-term prospects, with the overall Linux ecosystem spend increasing from $21 billion in 2007 to nearly$50 billion in 2011.

Read that bold-faced line again, for good measure.
The paper IDC references is here.
The day job’s high performance storage platform, JackRabbit, runs often as a Linux machine or cluster (though can do others if requested). This is a segment of the market that, if we believe these numbers, should be growing by about a factor of 2 in 5 years.
Wow.
