Hi @tipu!
Just got a tip from someone and went to your page! How cool is this post! Did you know that after spending a few weeks on Steem, I did exactly this? Download a VMWare image for the first time in my life (just a quick note, that was 17.04, so I think your post is a little outdated maybe), then installed NPM, Python and the Steem-libs and cli. I'm not a developer, but when I'm focused I can be a fast learner :)
BTW, all Steem-related stuff seems to work fine with Ubuntu1704, just so you know :)
When is the next episode of this series? Can't wait!
Steem on!
