This is a re-post from my blog at http://blogs.oracle.com/storageops/entry/handy_space_monitoring
Semi-real-time space monitoring is pretty straightforward with
ECMAScript & XMLRPC. I've never really been a fan of using used
+ avail as a metric; it's simply too imprecise for this kind of
work. With XMLRPC, you can gauge costs down to the byte, and with
So I decided to create a "Stuff Blog" to document my adventure trying to sell down all the stuff in my life. Most of it I don't need, and I want to get rid of as much as is practical.
Just watched "The Flaw". It's an entertaining and surprisingly unbiased documentary covering the myriad causes of the 2008 financial disaster from which the world is still recovering.
Watched the keynote today. Am I going to get an iWatch? No. Here's why:
I had some issues with my Garmin 910xt, but eventually I fixed the mock tri file. Woot! Next time, I'll disable all auto lap functionality before starting the tri, because apparently that's what interferes with the run data & corrupts the file.

A frequently-asked-question on ZFS Appliance-related mailing lists is "How often should I scrub my disk pools?" The answer to this is often quite challenging, because it really depends on you and your data.
Usually when asked a question I want to provide the answers to the questions they should have asked first, so that I'm certain our shared conversational contexts match up. So here's some background questions that we should have answers to before answering the "How often" question.

"Hey, bud, we need some new storage for Project Qux. We heard that this [insert major company here] uses a product called the Oracle Sun ZFS Storage Appliance as the back-end for their [insert really popular app here]. We want to do something like that at similar scale; can you evaluate how well that compares to XYZ storage we already own?"
So you get in touch with your friendly local ZFS sales dudette, who arranges a meeting that includes a Sales Engineer to talk about technical stuff related to your application. The appliance, however, has an absolutely dizzying array of options. Where do you start?
I really, really like the place that I work. The commute is amazing. The facility is breathtaking. My co-workers are stunningly enthusiastic, skilled, and intelligent. My pay is... well, good enough to get by :-) Recently a thread popped up at Slashdot in which a lot of commenters trashed Oracle, and I felt a need to set some of the record straight.
I've recently been chiming in on the Garmin forums about my 910xt watch and Garmin VivoSmart. The frustration of users not knowing how to use their fitness trackers -- and blaming the devices for not being the magical weight loss talismans they thought they were! -- is palpable.
