chrome
chrome disappeared from computer today. obviously something went wrong with yesterdays update. no problem. i'll just google a solution. oh wait. hrm. okay, the links are there in /bin /usr/bin. they point to /etc/alternatives. which goes absolutely nowhere. okay i'll just uninstall chrome and install it again. what's the command for yum uninstall? i'll just google it. oh right. amazing how we've become so dependent on a thing that didn't exist when i started using computers for a living. anywho. yum by itself led me to yum reinstall. which did the trick. wee!
