Presentation of my bachelor's thesis at ETH Zurich BitThief is a free loading BitTorrent client, that is, it downloads from the swarm without uploading. As a part of this project, following goals were achieved. - Integrate meta-search engine - No hard-coding i.e. make system fully user configurable - Allow users to filter results using query strings - Show latest torrents on user's chosen categories such as movies, TV, etc.
