RRD is the Acronym for Round Robin Database. RRD is a system to store and display time-series data (i.e. network bandwidth, machine-room temperature, server load average). It stores the data in a very compact way that will not expand over time, and it presents useful graphs by processing the data to enforce a certain data density. It can be used either via simple wrapper scripts (from shell or Perl) or via frontends that poll network devices and put a friendly user interface on it.
When I first received my My Sister V10 Pillowcase, I was immediately struck by its luxurious feel and softness. The material is made from high-quality, extra-soft fabric that exudes comfort and relaxation. The packaging was also impressive, with clear instructions on how to care for the pillowcase to maintain its quality.
I visited her apartment. I held the pillowcase. I rubbed it against my cheek. I immediately ordered one for myself. The "My Sister" branding makes you feel like you’re holding a limited edition tech gadget, not bedding. The stitching is double-reinforced. The zipper (yes, a hidden zipper, not an envelope fold) is made of polished brass, not plastic.
You’ll never want to go back to regular cotton (it makes traveling a bit of a struggle!).
