Fedora codenames have been rather peculiar or silly in recent history with names like Beefy Miracle for the Linux distribution. The Fedora 20 codename is also unique.
After an extended voting period
between names like Chateaubriand and Cherry Ice Cream, the most populous vote for the next Fedora codename ended up being Heisenbug.
For the non-software developers, as described by Wikipedia
, "Heisenbug is a computer programming jargon term for a software bug that seems to disappear or alter its behavior when one attempts to study it."
Fedora 20 "Heisenbug" is expected to be released in late November with many new features
for the Red Hat sponsored Linux distribution.
