We're talking about 60 lines of python for the "server" and 90 lines of python for the "client".
That's a weekend hack, not a Dropbox clone.
It happened so many times in the past, that I'm patenting a method of getting on first page of HN:
1. Write something
2. Call it a dropbox clone
3. Congratulations, apparently no-one bothers to check if that "something" does anything even remotely similar to dropbox:
- does it have a GUI client with a highly polished interface?
- does it have an installer?
- does it have conflict resolution to reconcile changes made on different computers?
- does it try to not corrupt files if download/upload fails in the middle?
- is it self-contained or do you first have to install, say, python interpeter?
