When a company considers virtualizing some part of its infrastructure what is really wanted to be virtualized? The entire machine? The OS? Software within the OS? What other features are needed? These are some questions I would like to hack out with others so come join in the foray.

Historically, DBMS were invited to divide program and data. The idea was to have a single logic (DBMS) that is aware of all the data a company is working with and some clearly defined interfaces to access these data (SQL). The information is stored in few files in the file system of the underlying operating system. Today this view should be changed again ...

In computing there are two terms which are often confused: encoding and enciphering. One of them, with 'cipher' in its name, usually best refers to something that is cryptographically enciphered which means it was mathematically mangled in a fashion that the result, regardless of the input, is fairly random, patternless nonsense to the un-key-assisted eye. The other term refers to simply changing data from one form to another at is basic level. One type of encoding is 'base64' encoding, which is used through many areas of computing and can be explained much more-simply than most cryptographic cipher functions (in my opinion). This article is to show how, on many levels, Linux Just Does That.

Every day it seems I find something new that Linux Just Does. Last week I finally decided I needed to learn about "shared storage" and started asking the resident experts here, who all pointed me to YaST. Much to my surprise iSCSI is built into YaST and works out of the box with SLES without much more than ten minutes and an understanding of the technology. For the quickest understanding of shared storage I can muster this article is now being created. Hopefully it will be as enlightening to others as this topic was to me.

Working at Novell in the Support organization I work with some of the best troubleshooters in and throughout the world. Many of the steps used in troubleshooting are common sense and laughed about commonly online ("Is it plugged in") and while these specifics are not that useful most of the time there are general practices that I have learned and feel need to be shared. The purpose of this article is to group everything that may help troubleshooting generally (and in some cases, specifically) for the benefit of those who may not have been in a support organization for several years. This is by no means the end-all, be-all of troubleshooting and I am by no means the best, but working in Novell's Support Forums some of these skills could speed up resolution times for those seeking help or even prevent the need for outside help altogether if applied.
