How I Built a Home Computer Lab, Changed My Life and Saved the Earth - Andresen
Bob Andresen, CA, tells an interesting tale of what happens when you start configuring your own home computer lab. His abstract follows:
This paper describes the choices, problems and solutions the author encountered while building a home computer lab, utilizing corporate equipment that is no longer powerful enough to run production workloads. Training classes alone won’t help build new expertise. What is learned in an expensive corporate class can easily be forgotten through non-use. Discarded hardware can be used to maintain and enhance skills in “new technology”. We’ll examine options for obtaining hardware and software to set up a small home network and to build expertise in new technologies that will allow one to keep a job with the current employer or find a better one elsewhere.
Introduction
Mainframe Limericks
With apologies to Oscar Wilde, mainframes are too important to be taken seriously. After all, laughter is one of our most profound signs of intelligence, understanding, and ability to adapt. For that matter, so is the mainframe – so they go together naturally! With that in mind, I’ve put together a few mainframe-themed limericks. Enjoy! – T-Reg
SURVIVOR – THE CORPORATE JUNGLE - Denise P. Kalm
The IT world has changed. With job losses exceeding 400,000 in the last four years, survival in this New Age requires much more than just putting in a good day’s work. The tools and strategies you need include: career assessment, ‘managing up,’ personal public relations, networking and much more. Learn how to outwit, outplay and outlast the competition – to thrive, instead of just survive – in this one-hour presentation.

THE STORK CORRELATION - USE & ABUSE OF STATISTICS IN PERFORMANCE & CAPACITY PLANNING - Kalm
Terms like “mean,” “standard deviation” and “correlation” are used frequently in our industry, but how many really understand them? And how often are statistics misused, creating confusion and misunderstandings, when their main purpose is to communicate your results more accurately? This paper will include a review of pertinent statistics, how they are derived, and where and when to use them in performance and capacity planning.
Statistics can be fun and increase your decision-making confidence. Now, if we can just get past the terminology and the math…and remember, it is often more art than science.
“Statistics is a systematic method for getting the wrong conclusion with 95% confidence.”
The Service-Oriented Organization - People, Politics and Pitfalls - Denise P. Kalm
As Garrett Hardin noted in Tragedy of the Commons, people value more what they own than property held in common. People litter in public parks, when they would never consider messing up their own yards.
In a Service Oriented Architecture (SOA)-enabled enterprise, services and servers are a common good; they are not “owned” by a line of business or a technology team. One can solve the technological challenges of SOA and still fail because the organization is not in sync with SOA design; organizational dynamics matter. The share-everything compliance challenge is just the beginning; in fact, the very structure of an organization probably will have to change.
Learn how you can transform your company to a Service-Oriented Organization (SOO) to reap SOA success.
