Some folks are STILL trying to justify violence on religious grounds. Very sad.

Christ was very clear “Love your neighbor and your enemy as yourself.” You can SAY you’re Christian and do hateful things all the time, and none of us is perfect (Methodists like to say we’re trying to keep on a walk toward perfection, knowing that is not a walk we will complete), but you really are not a Christian if you are preaching hatred of … any … one … most especially and saying this hatred comes with God’s approval. Sigh. Oh – and the bit about which prophesy is being fulfilled and when – don’t bother. He’s coming back like a thief in the night and no one will know the day or time of His Coming until it happens. Anyone who thinks they can decode specifics out of Revelations is just wrong, from Christ’s own mouth. As for extracting literal rules out of the old testament, that would be a neat trick if anyone could do it figuring translations, symbols, arcana of math and all that, but the new covenant tempered all those things with the rule of Love anyway.

Book Review: Oracle PL/SQL Performance Tuning Tips & Techniques

“Oracle PL/SQL Performance Tuning Tips & Techniques” by Michael Rosenblum and Dr. Paul Dorsey is a book you should read soon. A quote from Oracle’s Bryn Llwellyn in the book’s forward says it all “Every professional PL/SQL programmer should study this book and act upon its teachings.”
Misha and Paul take the scientific route to performance, providing readers the how-and-why of effective performance. The first chapter sets the tone showing how performance is an aggregate typically of nine-steps from execution of code on the client side, through middleware, to server, and back again to the client. Learn how PL/SQL works from two of the best whose shared stories of actual issues underline the importance of performance planning and thinking.

Windows 7 error “key not valid for use in specified state”

When you see that error upon trying to install or upgrade something on your Windows 7 64-bit machine, chances are that it is caused by a Windows Security update that you need to uninstall.

SLOB Failing To Generate AWR Reports? Red Hat Bug 919793!

This is a quick blog post to help folks that are testing with SLOB at high user (session) counts. The situation may arise where you are testing SLOB on a large configuration, with or without SQL*Net, and the SLOB driver (runit.sh) is failing to produce Automatic Workload Repository (a.k.a AWR) reports.

This problem will generally be seen on RHEL 6 variants that implement the much maligned /etc/security/limits.d/90-nproc.conf method of preventing fork bombs. For more information on this configuration file please refer to Red Hat bug 919793.

If you are not getting AWR reports under the condition I describe then the problem is most likely due to 90-nproc.conf short circuiting the ulimit(3) tuning you’ve established.

The 7 Deadly Sins of Cloud Computing

As if anyone needs to be reminded, there’s a ridiculous amount of hype surrounding clouds and big data. There’s always oodles of hype around any new technology that is not well understood—I believe the correct term for this is product marketing. There are at least seven deadly sins that can be committed when determining a […]

The Big Data Job Gap: Where are the Platform Scientists?

Big data continues to live up to its reputation for disruption as it gnaws away at all of the entrenched constituencies – IT silos, vendors, pricing models and now, careers; it’s about to get very personal. On the possibility side, there is a massive skills gap that needs to be filled. Everybody knows there aren't […]
