  • How should I start learning to code?
    Project Euler is an excellent set of problems to solve. Pick a language and start solving them. - Source: Reddit / about 9 hours ago
  • Question
    One great website for coding puzzles is Project Euler! It helped me so much when I first started programming, and when I got into making stuff for games I felt my ability to create unique solutions to problems was greatly improved. - Source: Reddit / 1 day ago
  • What are the best websites, books and apps to help me improve my c# skills?
    In a similar vein project Euler is a good one for practice problems if you have more of a mathematical leaning. - Source: Reddit / 2 days ago
  • Some fun, maybe bath based mini projects?
    "Math" and "mini projects" makes me think Project Euler. - Source: Reddit / 4 days ago
  • [OC] Number of consecutive primes generated by quadratic functions
    This visualisation was inspired by the 27th problem of Project Euler. I won't go into detail about the problem itself (if you're interested you can check it out at, but the idea was to look at how many consecutive primes would be generated by polynomials of the type n²+an+b. "Consecutive" means that you'd start with n=0, calculate the polynomial and see if it generates a prime number.... - Source: Reddit / 5 days ago
