    Don't Get Lost in the Random Forest

    by Wendy Istvanick
    As more and more data are amassed, focus has increased on getting information out of the data. Data Science is becoming mainstream. Machine learning can play a key role when using Data Science to find a solution to a problem. There are numerous algorithms used to programmatically learning about and from data. Random Forest is one that is both popular and powerful. In this talk I present the theory behind Random Forests and the Decision Trees form which they are made. Consider this theory your compass. I then move on to examine the attributes of a small data set. Consider the values and the relationships between them as your map. Finally, with our compass and map in hand I look at a Random Forest implementation that makes predictions from the data without getting lost.

    The Path to Build Happiness

    by Jenn Strater
    In a healthy engineering culture, everyone is a part of the release process, but that’s not always the case for builds. Sometimes the developers own it. Sometimes the ops team owns it. In many organizations, no one owns it. Because of this, engineers have grown complacent with inefficient builds and even joke about how bad build times are. But it doesn't have to be that way. Now that she works for a company that focuses on build automation, Jenn realizes that many of the habits she developed as a software engineer are incredibly inefficient and can be improved with Developer Productivity Engineering. Join in to learn these tool-agnostic steps to achieve build happiness: * Measure your builds. * Analyze the data to see how developers and CI systems are running builds. * Optimize build script logic and the processes to run them. * Iterate to maintain build builds and happy engineers.

    The Background on Background Tasks in .NET Core

    by Scott Sauber
    Need to run a task in the background in .NET Core? There are lots of scenarios for background tasks ranging from a task that runs for a long time, or perhaps an operation that needs to be retried multiple times if it fails, and many other scenarios in between. While there are lots of scenarios for background tasks, there are also lots of solutions to this problem that can leave a .NET developer unsure of which to choose from. Solutions such as IHostedServices, BackgroundServices, Worker Services, Hangfire, and more. In this talk, we'll break down all of these solutions with their pro's and con's and when to choose one over the other, as well as a deep dive on how these all work under the hood.

    Who needs stinking servers!? Not you! Introducing the Basics of the Serverless Framework on AWS.

    by Dani Tornow
    An introduction to the Serverless Framework on AWS. This will show how to use the Serverless Framework to deploy some simple API endpoints with interactions with a NoSQL database. Using Ruby, these simple "run only as needed functions" will allow you to maintain a highly available and cost affordable API because you will no longer need to maintain servers to keep your APIs available. You can rely on AWS (or maybe another cloud provider) to do that heavy lifting for you. Get an introduction with a demo on just how easy it is to get a simple API up & running, persisting data to a database, and adding a basic authorizer. https://slides.com/danitornow/serverless-framework#/ https://github.com/danitornow/serverless

    REST, GraphQL, and gRPC: What's an API developer to do?

    by Erik Dahl
    Most API developers are familiar with JSON-based REST type methods used to define their routes. But GraphQL and gRPC have recently been introduced, and both have some key advantages that can be leveraged in certain situations. What are those advantages? When should you use GraphQL- or gRPC-flavored APIs? Are there security implications of these API protocols? We will explore the differences between these three options, as well as look at some concrete demos of each and see how they behave in practice. The demos will be done using ASP.NET Core, but the techniques and protocols are consistent across any language used to develop APIs.
