I got really nostalgic recently: This site great and I want it to stay alive.
So I thought: Maybe it's time for a rebirth?
My aim is to reimplement the challenges, make it open source and modernize the UI (a bit). I want to keep it very close to the original content.
You can see the project here: https://github.com/Entkenntnis/hacker.org. The project has just started, expect it to take some time to progress.
Anyway, if are any concerns about copyright, etc. I am open to suggestions. Currently, I am licensing the project as MIT and see it as great contribution to the open source world.
And just if you wonder: Solutions are stored as hashes, so you can not break (most) challenges by looking into the source code
