I just wanted to have that written down. > One thing that the last 4 years outside of Fedora has reinforced to me is how much of the computer world is NOT 64 bit. Most of the hardware in everything from the 900 mini computers in a standard car to the 10 or so in a washing machine are 16 bit and 32 bit ones. The average home computer is at least 4 32 bit cpus and a couple of 16 bit one's working behind the scenes of the 64 bit processor and GPU you do your work in. Intel is still used a lot in this 32 bit world and the compiler that is used is primarily gcc. Currently, many of the Red Hat developers who work on gcc and other tools are using Fedora (or older RHEL) to support this ecosystem which means that Fedora gets a lot more focus from build-chain problems than probably other operating systems. When they have to move to another operating system, Fedora becomes more and more the 'oh it's broken.. not on my XYZ OS, I'll have to spin up something in my free time to get to it.' -- Stephen Smoogen, Red Hat Automotive Let us be kind to one another, for most of us are fighting a hard battle. -- Ian MacClaren
