Creating a Realtime Reactive App for a collaborative domain

Tue, 02/06/2018 - 09:29
Sampling is a Bazaarvoice product that allows consumers to join communities and claim a limited amount of free products. In return consumers provide honest & authentic product reviews for the products they sample. Products are released to consumers for reviews at the same time. This causes a rush to claim these products. This is an […]

Event Stream Modeling

Tue, 01/02/2018 - 11:50
Recently, during a holiday lull, I decided to look at another way of modeling event stream data (for the purposes of anomaly detection). I’ve dabbled with (simplistic) event stream models before but this time I decided to take a deeper look at Twitter’s anomaly detection algorithm [1], which in turn is based (more or less) […]

Telling Your Data To “Back Off!” (or How To Effectively Use Streams)

Wed, 11/01/2017 - 08:34
Foreword Our Curations engineering team makes heavy use of serverless architecture. While this typically gives us the benefit of reduced costs, flexibility, and rapid development, it also requires us to ensure that our processes will run within the tight memory and lifecycle constraints of serverless instances. In this article, I will describe an actual case […]

Maintaining Test Data with the “someObject” Test Structure

Tue, 09/05/2017 - 16:35
Language: Scala TestTool: Scalatest How did we get here? When systems become reasonably complex, tests must manage cumbersome amounts of data. A test case that may test a small bit of functionality may start to require large amounts of domain knowledge about the system being tested. This is often done through the mock data used […]

Fri, 01/27/2017 - 11:18
So many folks are wonder what they need to do to make a career of User Experience Design.
