Nuke – the Ake-Less Build System

As C# developers, we are spoiled with a great language and awesome IDEs. Why do build systems like PSAKE, FAKE, or CAKE never really match the level of convenience and integration that we’re used to? NUKE is different. It is fully based on C# console applications and uses the type system to its full extent. You want your auto-completion, package management, debugging, refactorings, formatting, and navigation back? It’s available right there!

Beyond Facial Emotion Recognition

In this talk, Wilder will introduce the audience to a new, augmented, Facial Emotion Recognition dataset and a Deep Learning model. With its basis on the FER 2013 dataset, used by a Kaggle(1) competition and also referenced in the paper by Ian Goodfellow et al(2), Challenges in Representation Learning: A report on three machine learning contests; Wilder augmented the FER2013 32,298 images by adding the Celeb Dataset(3), which contains 202,599 images of celebrity faces, exploring the magnitude of gradients around edge corners by extracting extra features from the faces using the Histogram of Gradients.

In the Cloud Message Queue Is an Implementation Detail

We all design distributed systems for the cloud. Do we really know why we design them the way we do? Let’s look at some real-world architects and examine the way they designed their systems. Or event better, forget about all the lofty architectural ideas. Architects design their systems based mostly on their subjective experience. Let’s look at hard facts.

Introduction to SQL++ for Big Data: Same Language, More Power

The most popular databases in the world all speak SQL, and almost 60% of Stack Overflow members use SQL. SQL is the query language that dominates when it comes to interacting with data. Data has changed since the 1970s; it’s no longer just stored in flat tables, but as rich, hierarchical object structures like JSON. SQL isn’t dead though, it just needed to evolve a little bit.

Mass Migrations to the Cloud (Or: How to Eat an Elephant)

Q: How do you move hundreds of interconnected applications from your data centre to the cloud? A: Like you eat an elephant, one bite at a time.
But where do you start? How fast can you go? What tools and people do you need? How do you keep track of progress?

Domain Storytelling – Facilitator’s Guide to Enhance Learning in Your Organization

In order to understand business rules and processes in a complex enterprise environment one must learn the language in which the business operates, i.e. a domain language. This talk will present Domain Storytelling as a lightweight technique that helps teams learn the domain language in a close collaboration with domain experts as well as providing strong hints on subdomains and contexts for implementation to kick off in a right direction.

Choose Your Path: A Guide on When to Use NoSQL

Yes or No…SQL? (ok, no more puns) If you’re like many developers, relational databases are your bread & butter. They’ve been the standard; it works. And then…NoSQL databases came along. With several NoSQL options available, do you switch because it’s new? Better? The “Future”? In this talk, Adrienne guide you on how to make your own decision (which may not always end with a NoSQL solution)!

Getting ready for Declarative UIs with Unidirectional Data Flow using Kotlin Coroutines

Unidirectional Data Flow (UDF) is a powerful technique that enhances our Reactive apps to work deterministically. Synchronising our views with fresh data was never an easy task to accomplish. For this same reason, there are mechanisms that support us to make that possible. Surely callbacks were a thing in the past, however, they were an antipattern themselves due to the lack of readability.

Machine Learning: An Engineering Perspective

Shipping Machine Learning into production turned out to be less about ML and more about Engineering. As Martin Zinkevich, Research Scientist at Google puts it: “To make great products, do machine learning like the great engineer you are, not like the great machine learning expert you aren’t.”
In this talk we explore an experience of considering ML Engineering through the lens of best Software Engineering practices.
