South West Ruby #43

Join us at Immersive Labs in Bristol in July for an in-person South West Ruby meetup featuring:

🍺 great food and drinks (sponsored by Immersive Labs)
💬 talks by Lewis Buckley (37signals) + Benji Lewis (zappi.io)

Schedule

18:00 - Arrive, grab a drink and some food, have a chat

18:45 - "Hey, spam or ham?" - Lewis Buckley

"Running an email provider like HEY means dealing with the inevitable spam, both inbound and outbound. I'll show how we filter out spam in HEY and how this same system can be used by your Rails app."

Lewis is a programmer at 37signals, in the Security, Infrastructure and Performance (SIP) team, working on Basecamp and HEY. He's a co-organizer of South West Ruby, and is now working remotely from south Devon.

19:30 - "Data Indexing with RGB (Ruby, Graphs and Bitmaps)" - Benji Lewis

In this talk, we will go on a journey through Zappi’s data history and how we are using Ruby, a graph database, and a bitmap store to build a unique data engine. A journey that starts with the problem of a disconnected data set and serialised data frames, and ends with the solution of an in-memory index.

We will explore how we used RedisGraph to model the relationships in our data, connecting semantically equal nodes. Then delve into how a query layer was used to index a bitmap store and, in turn, led to us being able to interrogate our entire dataset orders of magnitude faster than before.

20:00 - 21:00 - More mingling
