  • MonitoringScape – The past decade has seen a dramatic shift in how we build applications: clouds, containers and micro-services have displaced the old paradigm of static, monolithic infrastructure. The need for operational visibility has grown tenfold. Thankfully, the monitoring landscape has kept up with the times. We now have a choice of over 100 monitoring tools that provide excellent visibility to every nook and cranny of our IT stack. The modern monitoring landscape has something for everyone: on-prem installations, SaaS applications, open-source tools and high-priced enterprise monitoring suites. However, with so many tools to choose from, the monitoring landscape can be difficult to navigate. MonitoringScape is your guide to the new, exciting world of modern monitoring. Keep in mind that this is a community resource, so your comments and suggestions are very welcome.

  • Regular Expressions – Regular expressions ("regexes") are supercharged Find/Replace string operations. Regular expressions are used when editing text in a text editor, to: check whether the text contains a certain pattern find those pattern matches, if there are any pull information (i.e. substrings) out of the text make modifications to the text. As well as text editors, almost every high-level programming language includes support for regular expressions. In this context "the text" is just a string variable, but the operations available are the same. Some programming languages (Perl, JavaScript) even provide dedicated syntax for regular expression operations.
  • MySQL active-passive cluster | Your IT goes Linux – We will use the iSCSI Lun defined in our iSCSI cluster as a shared storage and we will run MySQL in active-passive (fail-over) mode using Pacemaker and Corosync cluster engine.

  • AIXchange: More Resources for AIX Newbies – As I've noted previously, there are more newcomers to the AIX platform than you might imagine. A company may acquire an AIX system through a merger or replace an old Solaris or HP-UX box with a current IBM Power Systems model. As a result, one of their IT pros suddenly becomes the AIX guy. So, now what? How does an AIX newbie get up to speed with virtualization and AIX?

  • Couch to 5k – C25K Running Program – C25K, is a fantastic program that's been designed to get just about anyone from the couch to running 5 kilometers or 30 minutes in just 9 weeks.

    With the help of the Couch to 5k program, In less than seven months, I went from a 47 year old, 104kg, 30 cigarettes a day sort of guy to an 82kg, 0 cigarettes, running 45 to 50 kilometers a week sort of guy. Ten months after finishing C25K I completed my first marathon. Since then I have run another 4 marathons, as well as 6 ultra marathons including a 100km race.

    And I'm not the only one, C25K has been responsible for getting thousands of couch potatoes up and running.

    Its secret is that it's a gentle introduction to getting the body moving, starting off alternating between walking and running small distances, and slowly building up until after 8 weeks, you're ready to run 5 kilometers or 30 minutes non stop.
