Andrew Cholakian on ZeroMQ:

ZeroMQ looks like an embeddable networking library, but acts like a concurrency framework. This talk will cover the basics of ZeroMQ, its Ruby libraries, and its use in building concurrent, asynchronous apps. The talk will specifically cover the use of ZeroMQ in Zed Shaw's Mongrel2 project, as well as some of the speaker's own projects.

Andrew Cholakian has been using Ruby/Rails for the last 4 years, and programming in it professionally for the last 3. He's currently employed as a Rails developer at You can read more about Andrew at

Benjamin Black on Riak:

Benjamain is a Seattle resident and looking forward to being a visiting presenter for LA Ruby Meetup this month. Mr. Black is a recognized expert in large-scale technology infrastructure design, implementation, and operation. He was an engineering director in the ECN group at Microsoft Windows Live, where he helped build one of the largest content delivery networks in the world. As the manager of website engineering at Amazon, he led the design and implementation of a new, layer 3 network for Amazon's production network. His work in the Internap R&D team resulted in his being awarded 3 patents in Internet routing and traffic optimization. Black is also co-author on several IETF RFCs on MPLS control protocols and IPv6 network operations.

Riak is a Dynamo-inspired key/value store that scales predictably and easily. Riak also simplifies development by giving developers the ability to quickly prototype, test, and deploy their applications.

Mitchell Hashimoto on Vagrant:

Mitchell resides in the Seattle WA area and too is looking forward to being a visiting presenter this month. Mr. Hashimoto is the maintainer of the Vagrant tool: which is a tool written in Ruby which enables developers to create and distribute development environments within virtual machines. The tool itself has only been available for the past 5 months, but its been gaining traction lately due to the vast benefits of working in virtual machines. Mitchell would like to talk about the reasons for working in virtual machines, how Vagrant enables you to do this, and the ways Vagrant has assisted real world companies.

Michael Wynholds on Cassandra:

Cassandra is a highly scalable and highly optimized Column Family data store, and is a leader in the field of NoSQL databases. Initially developed by Facebook and now open-sourced as a top-level Apache project, Cassandra is in use at Digg, Facebook, Twitter, Reddit, Rackspace and others.

Mike and a team at Carbon Five recently built a social networking site for a client utilizing Cassandra and Rails. In this presentation, Mike will go over the basics of Cassandra, and will discuss the Ruby / Rails code developed as part of this project. He will also introduce the existing Ruby-based Cassandra libraries available to the public (both used and not used for the project).

Mike is the President of Carbon Five - a software consulting shop based in San Francisco and Los Angeles. Carbon Five is an Agile shop whose technology focus includes Rails, Java and Javascript web apps, as well as iOS, Android and WebOS mobile apps.
