Jesper Louis Andersen
Creator of the eTorrent project

Jesper is a Danish programming language geek who has programmed in numerous different programming languages. He has a keen interest in weaving functional programming with parallelism and concurrency. He likes to try out new ideas from theoretic research by finding a real-world application and building a system around the idea in order to evaluate its usefulness. In the process he likes to apply knowledge from different areas of mathematics and computer science and he has a curiosity for anything new.

He is the principal programmer and leader of two open source projects, implementing the BitTorrent Peer-to-peer content distribution protocol in Haskell and Erlang respectively

He holds a B.Sc in Computer Science and is currently pursuing his masters degree. His studies has been centered around theoretical aspects of compiler design, semantics, type theory and formal verification.

eTorrent, writing Peer-to-Peer clients in Erlang

Erlang is perfectly suited for a modern distributed world. Part of this world is also a relatively new kind of client/server paradigm, namely Peer-to-Peer communication. We believe that this kind of communication is important to the modern internet and hence, the eTorrent project was born to gauge the usefulness of Erlang in a heavily distributed Peer-to-peer setting.

This talk is about using Erlang for implementing Peer-to-Peer clients. I claim Erlang made us write an efficient BitTorrent client in a fraction of the effort compared to other clients. I claim our client is more robust than the competition for normal operation. And I claim the Erlang mentality fits the Peer-to-Peer model well. I also explain how we utilize the Erlang platform to implement the client in an OTP-idiomatic way, and how we differ from the mainstream implementations.
