I'm one of many Aussies in Europe, a CTO and Web 2.0, SaaS, Google Enterprise (http://google.com/enterprise/), Citrix, Microsoft and Security (CISSP) guy.

I've done a bunch of stuff with Linux dating back to the mid-nineties (including distro development, clustering, embedded development, kernel coding and one of the first large enterprise installs).

I sporadically post to a blog at http://samj.net/ and occasionally log in to social networks including LinkedIn (http://www.linkedin.com/in/samjohnston/).

I contribute to a bunch of community based projects like:
 - CAcert (http://cacert.org/)
 - Debian (http://debian.org/)
 - Ubuntu (http://debian.org/)

I've launched a handful of technology companies and run a consulting firm called Australian Online Solutions (http://www.aos.net.au/) for over a decade which services large businesses around the globe.
