Red Hat has been on the leading edge when it comes to open source virtualization solutions. Red Hat Enterprise Virtualization provides robust virtualization from the network to storage and all the way to the desktop. The latest update, version 3.1, offers even more features to add to i...
This blog is the formal introduction to the CRaSH console for Mule on which I've been working for the past month or so. I've decided to interview myself about it because, hey, if I don't do it, who will? It is a shell that is running embedded in Mule and that gives command-line access...

Test results provided by vendors and “independent testing labs” often test for things that just don’t matter in the datacenter. Know what you’re getting. When working in medicine, you don’t glance over a patient, then ask them “so how do you feel when you’re at your best?” You ask t...
It is amazing how many open source software companies out there are trying to get hit by the same $1B bolt of lightning that hit MySQL without realizing that the MySQL result is not repeatable. Looking at the current batch of big data high flyers, from TenGen to Cloudera to Hortonwork...
1972: Most commonly used languages (Cobol, Fortran, Algol, PL/1, Basic, APL) all had complicated syntax. The prevailing thought process was to add new language syntax for every new feature. Writing a compiler for such languages was a nightmare. Then came “C”. The syntax was simple and...
Software bugs cost billions of dollars yearly. Correcting bugs earlier saves time, but too few do it. What is the impact of software bugs and the associated costs?
In January I attended the 10th annual Southern California Linux Expo. In addition to speaking and running the Ubuntu booth, I had an opportunity to talk to other sysadmins about everything from selection of distribution to the latest in configuration management tools and virtualization...

If you talk to the average software user, geospatial or not, about open source software you usually find three camps: Lovers, Haters, and Converters. Let's put these camps in crudely defined boxes: Open source "Lovers" are the lifers that live, breathe, and have never used anything bu...
In the first part of our series we described how to use find (and locate) to search for files using their names. Today we are going to review how to utilize find in a less common but very useful way. But first a few words on testing (okay, this might not be necessary for everyone, but ...
Before reading this article, I highly suggest to get familiar with all the concepts of the previous article regarding IO tuning. Your IO please, sir How is your IO characterized? Yes, this question has to be asked yet again. It’s a big difference when tuning for random access rea...
People who are familiar with me know that there are two things I’m not forgiving about. The first is backups, the second is security. If backups interest you, perhaps we can discuss it some other time. This time we’re going to discuss security. I’m going to outline in the following a...
