Ya... I don't get this article. I think the skills are good, but they aren't going to make you stand out.

If you don't know DNS, how did you get a website in the first place to start working on.

If you know how to code, you probably know how to get your changes onto the website with GIT.

And if you have made a website before you probably know how to use Chrome Dev or Firebug.

All this stuff except the HTTP, and Network Debugging would be covered in the first two weeks of any coding bootcamp.
