If you work around Linux regularly, in some ways the latest amazing news is… not that amazing. The New York Stock Exchange, where the world’s largest public companies trade their stocks, is now running on Linux. (Microsoft is not listed on the NYSE; they trade on the NASDAQ. Now *that* would have been a fun headline…) In addition the Chicago Mercantile Exchange also runs on Linux. While perhaps not as famous as the NYSE, the CME is one of the largest exchanges in the world. Even the Tokyo Stock Exchange is running on Linux.
