Trump revokes Washington Post's campaign press credentials

So I have to post you. I’m no Trump supporter but I did happen to hit the WP yesterday when the headline “Donald Trump suggests President Obama was involved with Orlando shooting” was live.

Handy Space Monitoring on ZFSSA

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
Javascript/ECMAScript you have some easy date handling for your

Stuff Blog: Day 1

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.

ZFS: Doing It Right

Imagine you're a system administrator, and an email arrives from your boss. It goes something like this:

"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?
