Next Meetup

XProf and Julia
• What we'll do Hello Erlangers! I am happy to announce our next meetup with the following agenda. Péter Gömöri: XProf 2.0 - evolution of tracing-based investigation How do you introspect Erlang/Elixir production systems handling large number of concurrent requests? There are certainly many ways. I’d like to show an intuitive, visual debugging workflow with XProf through real-world examples. XProf was originally created to hunt down performance issues. But actually we don’t face serious performance problems every single day. So, the second major release is focused to create a powerful query tool with which you can easily formulate questions about the system behaviour and get meaningful answers immediately. I will show features we added and how we aim to make the tool modular (with a split architecture) and extensible (via a generalized command framework) to fit multiple setups and use-cases. Csaba Hoch: How we made Erlang talk to Julia via C Erlang is an excellent tool for building robust systems, but it's not ideal for mathematics and machine learning algorithms. Fortunately, there are other programming languages that are made for those tasks: the Julia programming language is one such example. This talk will describe how we connected Erlang and Julia, so that our document handling system written in Erlang could use our machine learning algorithms written in Julia. Speaker bios: Péter discovered Erlang from his time at Ericsson. He later utilized his experience in various other industries from sports-betting to online advertisement at Erlang Solutions. Recently, he has joined Appliscale to fight with cloud-scale systems. Csaba is a developer at Cursor Insight Hungary, building the backend of motion analysis systems in Erlang and Julia. Previously he worked at Ericsson, and at Erlang Solutions where he helped create WombatOAM, an OAM tool for Erlang systems. He is also the author of the Vim Erlang indentation and the maintainer of other vim-erlang projects. • What to bring Your interest and your good mood. • Important to know Keep your RSVP up to date as we will use that one for pizza ordering.

What we're about

The Erlang User Group is a group of Erlang Enthusiasts who are interested in sharing their knowledge and meeting people who share similar interests. The group is open to Erlang Architects, Programmers, Project Managers, Software and Platform Innovators, and existing Erlang users as well as Erlang newbies and anyone interested in Erlang. We arrange and promote regular events involving Erlang including free seminars and workshops, followed by the customary Erlounge (i.e. beer, food and socializing).
