I work at Salesforce, which I joined by way of the ExactTarget acquisition. At ExactTarget, I was responsible for platform strategy, platform products, and developer programs. Among other things, my team built ExactTarget’s app platform (Fuel), third-party app marketplace (HubExchange), and online developer community (Code@ExactTarget).

Prior to Salesforce, I worked at Sun Microsystems, where I led Project Indiana, the effort designed to lower barriers to adoption of the Solaris operating system that led to the OpenSolaris distribution. OpenSolaris, in turn, led to Solaris 11. (Alas, Oracle discontinued OpenSolaris itself in late 2010.) Later, I ran the developer program and working on cloud computing.

Prior to Sun, I was CTO of the Linux Foundation (formed through the merger of OSDL and the Free Standards Group, where I was CTO) and chair of the Linux Standard Base (LSB), the Linux platform interoperability standard.

And prior to the Linux Foundation, I was cofounder and CTO of Progeny, a Linux distribution vendor that helped organizations build highly customized, streamlined platforms for Linux-powered products. Similar in spirit to today’s container-optimized Linux offerings (e.g., CoreOS), our Componentized Linux PDK (Platform Development Kit) was primarily targeted at vendors of server appliances, set-top boxes, and other Linux-based products. (Thanks to open source, the PDK lives on and is now maintained by a company called 64 Studio.)

I founded Debian in 1993. Debian was one of the first Linux distributions and also one of the most successful and influential open source projects ever launched. Debian pioneered a number of ideas commonplace today, including employing an open community that allowed (and encouraged!) anyone to contribute (much like how Wikipedia would later operate). And, with its integrated software repositories anyone could contribute to, Debian arguably had the industry’s first (albeit primitive) “App Store”. Today, more than 1,000 people are involved in Debian development, and there are millions of Debian users worldwide.
