hn-love will open that HN article you wanted to vote on when you get to a location where you are allowed to vote.
##Installation
npm install -g hn-love
##Usage
hn-love "Name of the Article You Want to Vote On"
When you run hn-love, it will quietly run in the terminal. When you are connected to the internet somewhere that you are allowed to vote, Chrome will open Google with a search query for the article you're interested in so you're one click away from upvoting. When you visit HN you will do so with a populated document.refferer value, so HN doesn't think you're a robot, which of course you are not.
Try connecting your computer to your mobile hotspot to test it out.
