think it's time for change in
the IT industry - time to stop
wasting money, time to start
delivering great software, and
building systems that scale
and last.”

DevOps means giving a s**t about your job enough

DevOps means giving a s**t about your job enough
to want to
learn all the parts and not just your little

People need to f****g work with each other and
not just occupy space next to each other.

“Heavy Windows server user here. We have 100+ windows server 2008 R2
and 2012 R2 machines in production and a massive .Net/C#
codebase.Currently it's a complete bastard of an operating system. It's
expensive, hard to manage even with powershell and DSC etc, difficult to
update, difficult to provision, complicated and to be honest absolutely
terrible licensing hell that costs us days a year. “
