Linus and the transformation

"Linux is rapidly transforming your personal and professional lives. And
open source technology is leaving a sturdy footprint on Wall Street. In a
bid to shave time off transactions, increase efficiency and cut costs, NYSE
Euronext, CME Group and the Tokyo Stock Exchange have all adopted open
source technology. Wall Street & Technology spoke to the man behind the open
source movement and creator of the Linux operating system, Linus Torvalds"

Then on page 2:-

*WS&T* : Why do you think Wall Street firms, who have millions of dollars
they can invest in IT, are so interested in open source?

*Torvalds* : I think a lot of them are also very interested in control of
their infrastructure, and that's one of the primary things open source gives
you. Yes, it may be available for free if you want to download it yourself
and install it, but as you note, for Wall Street that doesn't necessarily
tend to be a big selling issue. No, the big thing about open source is how
it makes everybody be in control of their own destiny.

By the way, that's absolutely not just about Wall Street - I think it's why
so many technical people are happy about Linux too. Even when they don't
necessarily personally get involved with the development, they know that
they could, and they see the process, and they can see how the code gets
generated. And Wall Street really does tend to have some special
requirements. Trading needs very low-latency networking, analytics needs
tons of CPU, yadda yadda. And with Linux, you really can tailor things (or
pay others to tailor it for you) to whatever specifications you need.
