This could be the most straight forward MacOS update I have ever performed (I have been doing them since System 7.5↗ ). This time all three machines (iMac, MBP and MBA) worked first time with no dramas. As always the first thing I did was a full TimeMachine back-up (I have been burnt before) and then downloaded a copy of the Yosemite install from the AppStore.

I have been installing and exposing SSH on most of the containers I have deployed, which I know is wrong. As I have been trying to do things in a more “devops” way I decided to do a little reading on how I can enter and leave running containers on my CentOS 7 instance without having to expose SSH or configure users. This is when I came across nsenter↗ & docker-enter↗ . As you can see from the following instructions and terminal session installing nsenter and then using docker-enter to connect to a running container is a breeze; ...

At least once a day I skim through a large number of blogs in my Feedly↗ feed using Reeder 2↗ , when I see something which catches my eye I send it over to Pocket↗ so it is sync’ed to all of my devices.
