How did they get their names
. A good list from Adobe to Yahoo. Most of them I already knew, but I didn't know about the origin of RedHat.
Red Hat - Company founder Marc Ewing was given the Cornell lacrosse team cap (with red and white stripes) while at college by his grandfather. He lost it and had to search for it desperately. The manual of the beta version of Red Hat Linux had an appeal to readers to return his Red Hat if found by anyone!
Also, I thought Yahoo was for "Yet Another Hierarchical Oriented Oracle"
