by on August 17, 2010 · 1 comment


A lot of Sysadmins and developers all over the world write, meet and talk about DevOps: How to collaborate better so we can deliver business value faster. The aim of DevOps is to get rid of the traditional way of thinking in silos inherent to development and operations. But how can You find out whether your organization is ready for DevOps?

Setting up an OpenSolaris pkg repository mirror

by on August 21, 2009 · 1 comment

Downloading OpenSolaris packages from pkg.opensolaris.org is extremely slow, at least here in Germany. As we were planning to upgrade our OpenSolaris boxes from 2008.11 to 2009.06 during a downtime, we needed a significant speedup.

Package Repository Mirrors

Fortunately, it’s pretty simple to setup a mirror yourself. Just grab the 7.2 GB disk image of the complete repository (from a OpenSolaris mirror nearby), copy it to your harddrive and get the preinstalled pkg server running. Then you’re only one command away from actually using it. Here are the steps, one by one in detail:

What do Sysadmins really think about Agile?

What Sysadmins Want

Most of us have seen, or at least heard of, the Mel Gibson movie “What Women Want”. It certainly is a tantalizing idea – being able to read the thoughts of other people. Now being able to read your sysadmin’s mind may not be at the top of your wish list, but, I bet there were a few times it sure would have helped fathom the meaning of that chill stare of contempt from across the table.

Or, I could just tell you what they’re thinking. For starters, what will be the production usage of that new feature you’re developing? Now, I know you’re not Nostradamus – but, you’ve thought about this, right? Any idea how many additional web server requests per user or session? What about the performance overhead of those additional database queries — what’s the longest running query now? Will you need to run that cronjob every five minutes or is once a week fine? These are just a few of the everyday concerns your sysadmin has while operating your company’s website. Have enough respect for his work (and yours) to do a bit of homework and come up with some numbers here.
