Spark DataFrames provide a structured API for analyzing large datasets using Spark. DataFrames allow users to parse, explore, transform, and summarize data through SQL queries and procedural processing. The demo shows analyzing 8GB of public tweet data using Spark DataFrames in Zeppelin notebooks. DataFrames simplify common data munging tasks and can also be used for machine learning, streaming data, and production data pipelines in Spark.
The combined world of IoT has reached a state where it's actuators spread from control systems in the industry into the city you live in and the privacy of your home. Now that everything is connected, we can abuse gadgets and devices for purposes they were not originally constructed for, and turn them against their users.
We will discuss current attacks, potentially 0-days, projects and Proof of Concepts that show the Internet of Shit that inhabits the Internet of Things, by OWASP's Top 10 attacks to these devices.
During this talk, we go into demonstrations that might inspire you to build a cool exploit, or radical security technology, during the conference.

openCypher: Technology Compatibility Kit (TCK) and Vendor ExtensionsopenCypher
Presented at the First openCypher Implementers Meeting in Walldorf, Germany, February 2017 @ http://www.opencypher.org/blog/2017/03/31/first-ocim-blog/
As a result of an engine rewrite with focus on more efficient data structures, PHP 7 offers much improved performance and memory usage. This session describes important aspects of the new implementation and how it compares to PHP 5. A particular focus will be on the representation of values, arrays and objects.
Burn down the silos! Helping dev and ops gel on high availability websitesLindsay Holmwood
HA websites are where the rubber meets the road - at 200km/h. Traditional separation of dev and ops just doesn't cut it.
Everything is related to everything. Code relies on performant and resilient infrastructure, but highly performant infrastructure will only get a poorly written application so far. Worse still, root cause analysis in HA sites will more often than not identify problems that don't clearly belong to either devs or ops.
The two options are collaborate or die.
This talk will introduce 3 core principles for improving collaboration between operations and development teams: consistency, repeatability, and visibility. These principles will be investigated with real world case studies and associated technologies audience members can start using now. In particular, there will be a focus on:
- fast provisioning of test environments with configuration management
- reliable and repeatable automated deployments
- application and infrastructure visibility with statistics collection, logging, and visualisation

Working with Complex Types in DataFrames: Optics to the RescueDatabricks
Working with complex types shouldn’t be a complex job. DataFrames provide a great SQL-oriented API for data transformation, but it doesn’t help much when the time comes to update elements of complex types like structs or arrays. In such cases, your program quickly turns into a humongous code of struct words and parenthesis, while trying to make transformations over inner elements, and reconstructing your column. This is exactly the sample problem that we encounter when working with immutable data structures in functional programming, and to solve that problem, optics were invented. Couldn’t we use something similar to optics in the DataFrame realm?
In this talk, we will show how we can enrich the DataFrame API with design patterns that lenses, one of the most common type of optic, put forward to manipulate immutable data structures. We will show how these patterns are implemented through the spark-optics library, an analogue to the Scala Monocle library, and will illustrate its use with several examples. Last but not least, we will take advantage of the dynamic type system of DataFrames to do more than transforming sub-columns, like pruning elements, and renaming them.
Keeping Spark on Track: Productionizing Spark for ETLDatabricks
ETL is the first phase when building a big data processing platform. Data is available from various sources and formats, and transforming the data into a compact binary format (Parquet, ORC, etc.) allows Apache Spark to process it in the most efficient manner. This talk will discuss common issues and best practices for speeding up your ETL workflows, handling dirty data, and debugging tips for identifying errors.

Advanced Flow Concepts Every Developer Should KnowPeter Caitens
Tim Combridge from Sensible Giraffe and Salesforce Ben presents some important tips that all developers should know when dealing with Flows in Salesforce.
In software engineering, the right architecture is essential for robust, scalable platforms. Wix has undergone a pivotal shift from event sourcing to a CRUD-based model for its microservices. This talk will chart the course of this pivotal journey.
Event sourcing, which records state changes as immutable events, provided robust auditing and "time travel" debugging for Wix Stores' microservices. Despite its benefits, the complexity it introduced in state management slowed development. Wix responded by adopting a simpler, unified CRUD model. This talk will explore the challenges of event sourcing and the advantages of Wix's new "CRUD on steroids" approach, which streamlines API integration and domain event management while preserving data integrity and system resilience.
Participants will gain valuable insights into Wix's strategies for ensuring atomicity in database updates and event production, as well as caching, materialization, and performance optimization techniques within a distributed system.
Join us to discover how Wix has mastered the art of balancing simplicity and extensibility, and learn how the re-adoption of the modest CRUD has turbocharged their development velocity, resilience, and scalability in a high-growth environment.

Providing Globus Services to Users of JASMIN for Environmental Data AnalysisGlobus
JASMIN is the UK’s high-performance data analysis platform for environmental science, operated by STFC on behalf of the UK Natural Environment Research Council (NERC). In addition to its role in hosting the CEDA Archive (NERC’s long-term repository for climate, atmospheric science & Earth observation data in the UK), JASMIN provides a collaborative platform to a community of around 2,000 scientists in the UK and beyond, providing nearly 400 environmental science projects with working space, compute resources and tools to facilitate their work. High-performance data transfer into and out of JASMIN has always been a key feature, with many scientists bringing model outputs from supercomputers elsewhere in the UK, to analyse against observational or other model data in the CEDA Archive. A growing number of JASMIN users are now realising the benefits of using the Globus service to provide reliable and efficient data movement and other tasks in this and other contexts. Further use cases involve long-distance (intercontinental) transfers to and from JASMIN, and collecting results from a mobile atmospheric radar system, pushing data to JASMIN via a lightweight Globus deployment. We provide details of how Globus fits into our current infrastructure, our experience of the recent migration to GCSv5.4, and of our interest in developing use of the wider ecosystem of Globus services for the benefit of our user community.
