Building own failsafe image using firefly scripts

I've put some distro-const scripts to the github repo at for anyone who wants to build their own illumos-based failsafe image. Current stuff was tested on OmniOS but also should work on OpenIndiana. Anyway the code can be simplified, so any pull-requests and customization are welcome.

Installing node-oracledb on OS X with Oracle Instant Client

I've been hacking an Apple OS X shell script to install href="" >node-oracledb. You
tell it where your Instant Client libraries and headers ZIP packages
are. It then installs node-oracledb, resulting in an
instantclient directory and a node_modules
directory. This automates the instructions href=""

The foundation of cloud-native computing

The older I get, the more engineering values matter to me — and the more I seek out shared values in those with whom I endeavor to build things. For us at Joyent, those engineering values reflect that we operate the software we make: we believe that foundational systems must be designed to be robust and high-performing — and when they fail in this regard, it is incumbent upon the system itself to provide the tooling to diagnose the errant behavior. These values are not new (indeed, they are some of the oldest in computing), but there are times when they can feel endangered.
