Quarantine Session

JOTB would like to welcome YOU at our very first virtual event, or as we like to call it: Quarantine Session. We know these are tough times for everyone but when life gives you lemons, you make lemonade, and when it gives you the internet and a quarantine, you get a bunch of coders together and make an online event.
Our online series is included with every JOTB 2020 ticket and can be purchased separately for anyone who can't make our live event. Make sure to pre-register and we will see you all very soon! 

Speakers

Agenda

17:00 to 17.30 Exactly Once Delivery is a Harsh Mistress by Natan Silnitsky

Is Exactly Once Delivery a pipe dream? Recent versions of Kafka have claimed they have made it a reality. In this talk, Natan Silnitsky will go over the different message delivery guarantees and the protocols that implement them. He will focus on Kafka's transaction-based messaging protocol, It’s trade-offs and shortcomings, and how it can help with many use cases that require atomic operations in today's modern distributed microservices systems.

17:40 to 18:10 How To Integrate Non-Developers in Data Flow Development by Marta Rivera

In this talk, Marta will explain how they develop and continuously improve data flow pipelines while integrating the input from non-developers. Their data streams include very complex calculations that need to be designed by researchers whose main skills are not necessarily coding. Specifically, she will share some tricks that worked for them to integrate research results as configuration files in Airflow, productivise Jupyter notebooks with Papermill and develop analysis dashboards with Bokeh for everybody in the team to evaluate the results.

18:20 to 18:50 Hybrid Cloud for Java Developers by Alex Soto

Hybrid cloud is an architecture that incorporates some degree of workload portability, orchestration, and management across 2 or more environments. In this session, Alex is going to conduct a live demonstration of hybrid cloud-native Java microservices, distributed across public and private cloud, with real-time load-balancing and fail-over using Kubernetes and Skupper. Don’t be the last one to board the Kubernetes Hybrid Cloud train! Even if you’re not deploying apps to hybrid cloud now, you might be soon.

19:00 to 19:30 A Year of Exotic Data Visualizations by Nadieh Bremer
"Data sketches" was a year-long collaboration between Nadieh Bremer and Shirley Wu, both freelancing data visualization designers. Almost every month they chose a topic and visualised it in an overly elaborate & geeky manner, while also writing extensively about the creation process. In this short talk, Nadieh will share a few of her most important lessons learned in the fundamental areas of data, sketching & coding. About how some months became favourites, what mistakes were made, and how they were overcome.
