# [2021.04.21] Fighting CentOS I first learnt about the existence of CentOS when I became interested in Big Data. Then there was no Hadoop distribution for Ubuntu, so I installed CentOS on my home PC. Now CentOS manages the two fattest servers in our lab. It's CentOS 7, first released seven years ago, oh yeah. For compiling some, code I need `glibc` of a higher version than that available, and it looks like there is no way to get it without being `root`. `glibc` lives too near to the kernel to be built from my $HOME.
