I downloaded parts of Slackware over a 2400 baud modem connection in 1993 - my start using Linux. So, I noticed the announcement of Slackware 11 with some nostalgia. I very much appreciate the fine work of Patrick Volkerding. (Even if I am now an Ubuntu user :-)
Software power: for me, Linux + other open source = Power
I am not talking about client side Linux, rather being able to build services using Linux and quality infrastructure software from the Apache Foundation, the PostgreSQL group, etc.
In the 'new economic era' of globalization and driving costs towards zero, Linux and open source play a huge role in staying competitive.
