What was your most most expensive bug? Can you imagine having a bug that got into production that cost close to $1,000,000? Beyond the monetary cost to cover losses there is the fact that they came close to missing an edition, which they have not done since the Great Chicago Fire in 1871.
It would appear the Chicago Tribune rolled out a new version of their software over the weekend without proper testing. It appears that the output was not compatible with the printer. It seems like a simple test run would have discovered this incompatibility before it was critical.
I am curious if it was a small patch, or a major upgrade. Many times small patches are roll-out without proper testing. The testing only covers the expected changes, and then they have unexpected consequences.
In mostly unrelated news: ICANN has installed IPv6 in their root servers. Unlike the Chicago Tribune, ICANN will be running IPv6 and IPv4 sin parallel for 20 years to ensure there are no bugs.
