Red Hat's Open Source AI Vision
Limited Capacity seats available

"Analytics, Machine Learning, and AI represent a fundamental transformation that over the coming decade will affect every aspect of society, business and industry. It will fundamentally change, how we interact with Computers - and how we develop, maintain, and operate systems. It's impact will be visible in our part of the universe much sooner than for the analog world. This deeply affects both Open Source in general, as well as Red Hat, it's ecosystem and customer base.
This talk will provide a perspective on Red Hat's thinking around AI in the broadest sense."

Global revolution in machine learning
Limited Capacity seats available

"Many researchers and developers consider machine learning and artificial intelligence to be the next global revolution similar to industrial revolution. It's known even today that machine learning and AI can have global impact on things we do on daily basis. Computers already substituted human being in various daily activities helping people to be more productive or enjoy life in a different way. Let's have a look at technical aspects how machine learning works, what are the main principles and how you can start with machine learning and AI."

Search and Learning-based Software Engineering
Limited Capacity seats available

"Search and learning-based software engineering is about the exploitation of optimization and machine learning methods for the software engineering domain. The goal is to move the practices in software engineering from the human-based to machine-based problem-solving. Search and learning-based software engineering has been examined, researched, and developed in the last decade in the academia. The research output has shown many useful applications for the industry. However, while the area is promising, less effort has been made to transfer those discovered methods from academia to industry. This talk tries to explain the transition opportunities of search and learning-based software engineering from academia to industry. The talk will present many possibilities for applications."

Container Image Storage Compression and Dedupe
Limited Capacity filling up

"Container images are known to be compressible. But there is no comprehensive evaluation of how much storage space can be saved through storage features such as compression and deduplication.

This talk presents quantitative findings of Container image reduction under different workloads using Virtual Data Optimizer (VDO) developed by Permabit and recently acquired by Red Hat. We discovered that storage space savings range between 50% and 85% on different workloads.

Building on these findings, we created an optimized Docker registry service on OpenShift that is capable of reducing storage spaces used by CI/CD by almost a magnitude."

Fedora in Education
Limited Capacity seats available

"On this session I would like to talk about using FOSS and more specifically Fedora for education purposes. I aim to answer why is it important for us to teach students about open source software and what are the benefits of going completely FOSS in education.

I also want to talk briefly about our Fedora classroom mentioned here: https://fedoramagazine.org/fedora-computer-lab-university/

what were the difficulties and how we manage it."

Analyzing Blockchain in Spark
Limited Capacity seats available

"I will show how you can leverage the containers and run the Spark cluster on top of OpenShift. For demonstration purposes, I'll be demoing the Blockchain analysis in Jupyter interactive notebook using the external Spark cluster running in OpenShift, everything dockerized.

The talk will briefly describe how Blockchain transactions work. How we can run various queries on the publicly available Blockchain data, graph algorithms such as PageRank for identifying significant BTC addresses and more.

Can developers use OpenSSL?
Limited Capacity seats available

"Last year, we asked 90 developers to generate/validate certificates using the command line OpenSSL. Why didn't they succeed? What do people think of the interface? What's wrong with the manual page and what do online tutorials lack? And what can be changed to improve the situation?

In our research, we focused on API of OpenSSL, a widely-known cryptographic library. We'll present multiple insights from the DevConf 2017 research booth, answering the questions from the previous paragraph.

We use OpenSSL as a real-world example to spark conversation on usable security. How to make products that are not only computationally secure but also usably secure for the end-users (be it your system administrator or your granny)?"

Building Streaming Recommendation Engines on Spark
Limited Capacity seats available

"Collaborative filtering is a well known method to implement recommendation engines. Although modern techniques, such as Alternating Least Squares (ALS), allow us to perform rating predictions with large amounts of observations, typically ALS is implemented as a distributed batch algorithm where retraining must be performed with the entirety of the data. However, when dealing with large amounts of data as a stream, batch retraining might be problematic. In this talk Rui will guide us in building a streaming ALS implementation using Apache Spark and based on Stochastic Gradient Descent, where training can be performed using observations as they arrive. The advantages of real-time streaming collaborative filtering will be discussed as well as the scenarios where batch ALS might be preferable."

Hacker's guide to Web Assembly
Limited Capacity seats available

"WebAssembly is a new low-level binary compile format that will do a better job at being a compiler target than JavaScript. It’s being called “the future of the web platform” and did you know that its promising features in terms of speed, reusability and safety has brought major browser vendors working together to make it a reality and the MVP is already available in major browsers.

Want to know how WebAssembly work? Why is WebAssembly so fast? How to build web apps using C/C++/Rust? In this talk we’ll look at history, basics, applications and deep dive into the core concepts of WebAssembly with help of live demos and coding.

Session Content :
- Introduction to WebAssembly
- Live Demos
- History & Need of WebAssembly
- Applications of WebAssembly
- Community Details & support Channels"
