Idea shamelessly stolen from petercooper: https://news.ycombinator.com/item?id=16859287

With the grow of paywalled content getting to the first page, could we please start marking it somehow? It could help avoid disappointment when a link leads to an inaccessible content.

Is there any set of problems to solve and applications to write which will make a better programmer without a doubt? I'm thinking about classic apps, like compiler (for deeper understanding of compilation process), designing and implementing a programming language and writing simple OS.

Have you other suggestions?

(of course I'm not talking about rewriting gcc, but few days of work just to get more information about how computers work and implementing the knowledge)
