As a former employee, that was my first thought when I read the post too. Every once in a while, I would stay late there and work on a little personal project for fun there. Sometimes one of my friends would be working late, and I'd just keep him/her company. After all, if I'm just going to do the same thing at home, I might as well take advantage of coding on my big monitor and comfy chair...
I check if there's indeed a mail server in DNS to avoid the hassle of waiting for potentially slow SMTP servers to respond - for most cases, it works and I end up catching bogus email addresses from the domain names themselves.
So, I'm originally from the same neighborhood (if I may call it that - shit, the place was just rice fields when we moved in) in Kathmandu and occasionally a Node.js hacker. It's really nice to see development in this field.
Great to see this on Show HN. I'm gonna buy you guys a beer next time I'm home.
