I have been messing around with C++ for a while but lately web programming has been getting more attention more and more. I'm a beginner when it comes to web apps and when I see websites like this (it almost feels like I'm running a native software on my operating system) I get very excited. How does one go about creating a website like this? What should I learn. What combination of technologies are used? Thank you and congratulations for such a great job!
