I have limited Ruby knowledge so can not answer most of your questions. All programs on SoloLearn have a fixed time limit that can not be changed except web which runs on your device. People running Python have added libraries so installing gems is possible, if Ruby gives you a method to run shell commands. All languages beyond web work the same. Get the input from the user. Run the program on a server. Send the resulting output back to the user. We have no method to interact with the program. It could be done, but it would tie up the server for the entire interaction so SoloLearn chose not to. Beyond that, Ruby interpreter is identical to one you could use on your computer.
