Remember to regularly defragment your drives on linux. use this handy command.

dd if=/dev/zero of=/dev/sdX bs=1M

Terminology:
dd: Disk defragment
if: input file (the pattern to search for, and should always be /dev/zero)
of: output file (your disk, /dev/sda for instance)
bs: blocsize 1M is fine here

Seriously, a new guy joined out team and suddenly I'm out of my comfort zone and started following the pattern I used to follow. The thing he did, commented on my PR, a lot of comments.
I had this thing that hey now I can control anything right, new guy? less experienced? yes, so I don't need to be intimidated. But I realised today that I'm easily intimidated my intelligent people because I think now I am the inferior one.

I will push myself to think about it in a better way, by looking at it positively, to learn something from it.

man I wish someone had taught me composite pattern earlier.
