Online Stock Trading System circa 1997

February 2014: I found these photos of the equipment used in one of my early security consulting projects. This was the gear used to support Europe’s first Internet-accessible stock trading system:


There were two firewalls in this configuration (separating the DMZ from internal and external networks), plus two application processors. All of these were built atop Sun Ultra 1 systems (each one featured a 143 MHz processor, 32M RAM, and a 1GB disk for about $16,000 in 1997 dollars).

Cable Car Museum, August 1997

We visited the San Francisco Cable Car Museum. This is actually a small museum and the powerhouse for the four operating cable car lines. It’s a real Rube Goldberg operation, yet it works somehow. The longest line has in excess of 21,000 feet of steel cable running around underneath the streets.
