I guess not so much games/websites but something you can see yourself using. Roman numeral conversion is not one of those. Neither, for example is SICP's exam

I guess not so much games/websites but something you can see yourself using. Roman numeral conversion is not one of those. Neither, for example is SICP's example of Newton-Raphson. I don't want to bang on about it. They're fine books. Just could have used an better editor or some other constructive advice to make it less niche and more relatable. FWIW I also bought Learning Python which was meh, and Python Cookbook which is directly useful.
