Building a large pubsub-with-history system
| Projects in scope: * Building a large pubsub-with-history system (designing, scaling, distributing to multiple machines and profiling). Talk objectives: - Providing overview of practical lessons on scaling with Erlang including insight into problem domain. - HOWTO on 1.5mln of users online at the same time.

| A short story about Erlang internals and how they influenced the real life scenarios and a practical guide to some aspects of performance and highly availability. Last year we have given some thoughts about transition from C/C++ to Erlang which was ongoing. Since then the system has successfully reached production environment and we can validate our high hopes. During this talk I will present lessons learned, challenges we have met and pitfalls we have run into implementing and deploying a highly available system for session control and online charging. Talk objectives: To present challenges in creating and especially supporting a HA system based on Erlang, and give some thoughts about strengths and weaknesses of Erlang seen as a platform. Target audience: People developing erlang distributed applications, especially making use of mnesia.

MongooseIM - Messaging Server that Scales
| MongooseIM provides a unique instant messaging solution when
massive volume is required. The growth of social media communication has
resulted in the fact that the ceiling is quickly reached when
successful projects take off. MongooseIM secures performance and
stability. In this talk I present lessons
learnt when scaling messaging servers using common PC, cloud
environments or a dedicated data centre. I demonstrate what bottlenecks
we encountered and how to work around them in order to scale to millions
of users. I also explain why MongooseIM and Erlang are a good baseline
for building a custom messaging solution. Talk objectives:
to educate about MongooseIM, which is built around proven technology
Jabber/XMPP, as well as discuss how to build a messaging solution, which
will scale to big numbers. Target audience: People who know Jabber/XMPP or are interested in messaging servers.

Saving mankind with Erlang for dummies
| Sapir-Whorf hypothesis states, that people speaking different languages think differently. I argue that this is also true with formal languages. In this talk I will present results of bachelor thesis that I and Michał Konarski created. Also, I will show why we chose Erlang, why it was a good choice and what was its impact on software design. I'd like to show the idea of separate actors, message passing and its implications to fault-tolerance (and scalability). Also I'd like to show that Erlang is well suited for embedded devices. I will not try to teach Erlang, only show the ideas.

Taking Back Embedded: The Erlang Embedded Framework
| Erlang was originally designed to control telephony switches at
Ericsson which, by definition, are embedded systems. Somewhere along
the line the application area changed dramatically and now Erlang is
being used to tackle challenges which involve gratuitous amount of
parallelism and “The Cloud”. The Internet of
Things is the physical extension of cloud which describes how everyday
objects around us will become sources of data that will transform our
daily lives. Analysts forecast the number of Internet connected devices
to reach 50 billion within the next decade, which signifies that we need
to think of new ways to architect these new generation of connected
devices. This talk will demonstrate how, by
creating a layered architecture for hardware modules and partitioning up
complex systems in smaller units, testing becomes easier, runtime
errors are contained and the architecture becomes maintainable. Using
Erlang processes as compositional units to describe these systems is a
new proposal which stands out and challenges conventional approaches. Talk objectives: This
talk aims to provide an overview of the current state of Erlang in the
embedded domain and talk about our plans to help speed up the adoption
rate of Erlang in embedded projects. Target audience: Hardware
and software engineers interested in discovering new tools and
methodologies for tackling the next generation of connected embedded
devices.

proc_mobily - mobile Erlang processes
| This talk describes a part of my thesis which was migrating Erlang processes and integrating them with an existing multi-agent system written in Erlang. Talk Objectives: How to migrate Erlang processes inside and outside an Erlang cluster. |
