In the hacker culture, a hacker is a computer expert who enjoys to achieve novel and clever outcomes by engaging in programming tasks in a spirit of exploration.
In order to blog like a hacker, you should write posts in a smart, original, effortless, and enjoyable way, possibly using open-source software.
This is what I do: I write posts on plain text files, and then build the final HTML pages with Jekyll; everything from the command-line.
If you are a complete beginner, you should first get familiar with the command-line, and then learn a little bit about Git, and also GitHub.
After that, you’ll be ready to host your blog on GitHub Pages, for free!
