Earlier this week, I was asked (on LinkedIn) if I use #linux

I used to use #linux but I only have one Linux #server which is an Outline #server running #ubuntu 14.04 LTS on a #DigitalOcean #droplet in London (I will set up a second in Los Angeles or San Francisco when Outline supports managing multiple servers from one account).

Until 2010, I used #Windows as my #desktop OS and #linux as my #server OS. September 2010 was the start of my #Apple conversion; I went from zero Macs to three Macs in six weeks.

In Summer 2011 I started playing with #FreeBSD far more than I had in the past and migrated all of my servers during the rest of 2011 and early 2012. Since early 2012, I have not used #linux

#linux-based and #UNIX-based OSes are similar in their community support despite different scales to those communities. I prefer #BSD for various reasons, many of which I do not talk about publicly because it is not for me to share the exact nature of complaints made by my friends and I.

Comparing the efficiency of #Nginx and #Node.js installations between Linux and #FreeBSD servers, #FreeBSD is far more efficient when compared to cutdown Linux servers.

My desktops run #macOS and #TrueOS.

Anyone can work on anything but I do have my chosen favourites which happen to be the ones I work with normally which is completely normal and I would expect that of anyone or any company I worked with.

Personally, I build architectures solely made up of #UNIX/#BSD-based OSes for my businesses and projects.

#macOS and #TrueOS are the two human-computer interface options.
Servers run a variety of #UNIX OSes including #macOS (don't tell #Apple).
