Yep! Both of these applications are going to spend virtually all their time *waiting*. That means you don't have to stress about performance, and can concentrate on writing code in the easiest and cleanest way possible. To my mind, that says either Python or Pike; both languages have excellent networking libraries, but in this case, Python definitely takes the edge, because you already have broad familiarity with it. > Also, please provide a very high level strategy to implement (I am not asking > for script, but just enough so I can initially focus on learning those parts > of Python). > Start with the socket module: https://docs.python.org/3/library/socket.html Get to know something of how TCP/IP works, if you don't already. Then once you're ready to do your actual implementation, since you've considered using HTTP, I would suggest looking into the third-party 'requests' library for the HTTP clients (you can do everything with the standard library if you prefer, but you owe it to yourself to at least have a quick _look_ at requests), and one of the standard web frameworks for the server (personally, I use Flask, but any would do). You'll probably want a database back end to store the actual content; I strongly recommend PostgreSQL, which you can access from Python using psycopg2. If you don't like hand-writing SQL, you could use something like SQLAlchemy as middleware; otherwise, direct use of psycopg2 works just fine. Every part in this can be replaced without affecting the rest, but if I were doing this kind of job, these would be the tools I'd first reach for. requests: http://requests.readthedocs.org/en/latest/ Flask: http://flask.pocoo.org/docs/ psycopg2: http://initd.org/psycopg/docs/ SQLAlchemy: http://www.sqlalchemy.org/ You asked for a "very high level" strategy. This is so high level it's practically in LEO, but it's a start :) ChrisA -- https://mail.python.org/mailman/listinfo/python-list
