And what software?
All the Macs run El Capitan and content is kept in sync with Google Drive and Resilio (aka BitTorrent Sync) for the more sensitive stuff. Software installation is scripted which makes setting up new installation a cinch. I always have an instance of iTerm2 v3, enhanced with HomeBrew, running and work wouldn't be the same without HipChat or Hangouts (and VirtualBox for any Windows nonsense). Alfred 2 replaces Spotlight and enables clipboard history -- as well as a host of other functionality (it's great for those who love keyboard shortcuts). f.lux is a must-have for those who have trouble falling asleep at night.
Photos taken on the phone are automatically uploaded to Google Photos and SmugMug, which is where all my photos are stored, via their Android app.
-Video transcoding on the desktop is handled by Handbrake whilst Flexget, a kick-ass piece of software, keeps all my media automatically up-to-date. Transcoding to the Roku is handled by Plex Server running on the iMac.
+Local media is served from the iMac via Plex Server to the Roku. Keeping the media library up-to-date is tasked to Sonarr and Couch Potato.
Python is my language of choice but I also dabble in Go, C, BASH (and Bourne shell), PHP, and Java (for Android development). All recent code is kept on GitHub.
My browser of choice is, of course, Google Chrome loaded with my favourite plugins: 1Password, Hangouts and Pocket.
I have tried to move my working set of software into the Cloud. All my website passwords are random and tracked in 1Password; I use either of di.fm or Google Play Music for listening to music; Google Apps is used for Mail, Calendar, Contacts, Docs and Tasks; and Pocket for "tl;dr" functionality.
