• SPARK with C* (and testing/modelling in Ruby)

    Location visible to members

    Thomas Rogers (github.com/thomasrogers03) will be presenting the work that has gone on at Ficstar to best use Cassandra. He will be discussing some of the gems he has created for Cassandra and the work he is doing with Spark. The work he has completed is crucial to the day-to-day operations of Ficstar. They lead to easy data-ingestion, data intelligence and data optimization in the world of retail competitive intelligence and price optimization. If you would like to pre-read, check out his GITHUB repos and download his gems.

  • Considerations for Building Complex Systems

    Paytm Labs

    For this meetup we are excited to be joined by Eric Lubow. CTO of SimpleReach who will be discussing what to consider when building complex systems at scale. What You'll Learn At This Meetup: When people talk about building systems, they usually think about data storage or data processing. There are many other things to take in to consideration like data transport, capacity planning, monitoring, homogenous vs. heterogenous architecture, micro-service vs. monolith and many more. We will take a look at a framework for some ways to go about making those decisions and how that framework can be applied in real world circumstances. * A big thank you to Paytm Labs for hosting! About Eric Lubow: Eric Lubow, CTO of SimpleReach, began his career building secure systems at Guardian Digital before joining Conductor.com, where he developed and ran their ad systems. After graduating from Rutgers University with a degree in Information Systems, Eric did multiple tours with the U.S. Army including serving in Iraq as a Lieutenant and Albania as a Captain. He is a board advisor for the IronMatt.org charity for pediatric brain tumors, a mixed martial artist, motorcyclist, and seasoned skydiver. Eric is also co-author of the book Practical Cassandra.

  • Building smart bots with data analytics, machine learning, Spark and Cassandra

    For this meetup we are excited to be joined by Hanneli Tavante, who is a developer addicted to code, learn new programming languages. What You'll Learn At This Meetup: Why bots? Bots can be used in many scenarios - auto replies on IRC, Slack, Github and so on. But bots can also be used to help you on daily tasks! Depending on your routine, smart bots may be able to reply emails, answer questions on chat, remind you to do some activities and so on. Bots can be much more than a Devops Friend tool! This talk is going to talk a little bit about how to identify situations that a bot could help you, possible ways to build them, the challenges and the some things that may go wrong. Some topics: - Bots: helping me to avoid some mechanical or repetitive tasks since 2009 - My first (dummy) bots - First attempt to make bots smarter - the brute force way - Collecting data to feed bots intelligence - Cassandra and Spark - essential tools to collect several analogical events and turn them into data - Interpreting the results - applying some mathematics on it - Making smart bots with some machine learning basics - Real case - put bots to manage meetups- Points to improve - Where could you apply this idea? - Some epic fails - Notes on security and other issues About Hanneli Tavante: Hanneli (@hannelita) is a developer addicted to code, learn new programming languages, blow capacitors, do some C programming and commit useful (or not) code for random Open Source Projects that she finds at Github. She tries to help community with blog posts and organising NoSQL, programming languages and Math/Physics/Science meetups around the globe. She also likes Math, Lego, dogs, hardware and coffee.

  • Web crawling, APIs and other great automations at Ficstar

    Thomas Rogers of Ficstar Software Inc will talk about the uphill battle that has been fought in learning the intricacies of Cassandra usage at scale. You will hear points about: • dealing with the operations of Cassandra at AWS • automating deployment strategies • creating the necessary framework with which to relieve the pain of data modelling • creating the testing framework that allows for proper TDD of any cassandra models in unit tests • satisfying API routes • using our data to empower the right e-commerce and retail decisions • and possibly, much, much more....

  • Ruby Models InC* (In Cassandra)

    Location visible to members

    One of Ficstar Software Inc's Engineers has developed a rather elegant way of using Cassandra and obfuscating the need for many of the access to data modelling, CQL, etc... In much the same manner that a true model (in MVC) would remove the need to write any queries, create any tables, or figure out how to store data, Thomas Rogers has created a way to do this in a very Ruby way. Come visit us for a very intimate gathering at DeepLearni.ng (http://deeplearni.ng) in the heart of the downtown core. As usual, we will be offering food from DataStax / Planet Cassandra and refreshments from DeepLearni.ng (http://deeplearni.ng/) themselves. Please arrive promptly and if you cannot make it that day, please cancel your RSVP.

  • CSC301 (Cassandra Studies Course) - Paxos, Tuples and User Defined Types

Following this series, I will be hosting a hands-on data modelling class sometime in late June or early July. Schedule: 6:30 - 6:45pm: get settled into Brightlane, grab some food 6:45 - 7:30pm: dive into Paxos (light weight transactions), Tuples and User Defined Types 7:30 - 7:45pm: Q&A 7:45 - 8:15pm: networking Get ready for this as Cassandra Day TORONTO is coming in October and we will issue a call for speakers. SHAMELESS PLUG * Ficstar Software Inc (http://www.ficstar.com/careers/) is hiring and could use your help! We are looking for great Ruby developers with a penchant for Cassandra, Kafka, Storm, Spark and Solr/Elasticsearch. If this sounds interesting and you would like to work with me - hit me up at [masked]. ** If you are gainfully employed and know of someone looking for work that you think is awesome, please let me know, I'll be in your debt.

  • Lambda-ssandra [Lambda architecture backed by Cassandra]

    The BrightLane Building

    How did I push an organization to the point where they are now processing hordes of data in real-time along with historical aggregations? Architecting a system that is ALWAYS ON and never faulters, while migrating away from a LAMP (well LEMP) stack was not the easiest of endeavours. I'll talk about some of the issues we've faced, some of the problems in data, processing and people, as well as take you all through the thought process of going from a MySQL monolithic app to a highly distributed, highly-available, real-time SaaS. As usual - DataStax will provide food and possibly drinks.

  • What are Cassandra anti-patterns? (Jeopardy with prizes)

    The BrightLane Building

    Let's discuss the intricacies of WHAT NOT TO DO in Cassandra. This will be run as a Jeopardy game and tutorial. I split the room up into teams and pick three people at random to represent that team. Whichever team gets the most points at the end of the night will receive the top prize. The second place team will receive a 2nd place prize. The third place team will receive the consolation prize. ALL PARTICIPANTS will receive an awesome night and education for FREE! Thanks Planet Cassandra!
