Last week post. Slow week, caught up with lots of pending stuff.
#1 Why Docker Is Not Yet Succeeding Widely in Production. Old but still relevant HN discussion regarding Docker. I've been experimenting with Docker for the past three weeks and it seems to be more stable and feature (v1.10.1) compare to the earlier version (two years ago) I've tried. Expect more write-ups on Dockers and Vagrant for coming weeks.
#2 Do you really need 10,000 steps a day? (HN discussion) For a healthy and active person, the daily 10k steps may not be necessary.
#3 Vagga. The equivalent tool I can think of right now is Otto. Good alternative to Vagrant and Docker to bootstrap your development environments.
