NextRoll

When it comes to increasing diversity in tech, AdRoll doesn’t have all the answers, but people are investing in potential solutions and having open conversations.

Today, we are open-sourcing TrailDB, a core library powering AdRoll. TrailDB makes it fast and fun to handle event data.

How AdRoll achieves peak performance thanks to our flexible RTB testing framework.

The AdRoll Data Science Engineering team is proud to announce the New AdRoll Data Analysis (NADA) platform that is fast, comprehensive, and operates at scale.

The AdRoll Real-Time Bidding system is a complex affair. Many things have to go right to keep it from running off the rails and, well, things don’t always go right. Accepting that and dealing with it is a good chunk of the engineering effort behind the RTB system and in this article I’ll discuss one of the fun resolutions.

A guide to the (sometimes not readily apparent) steps necessary to set up a PySpark cluster on AWS Elastic MapReduce (EMR).

Announcing gulp-react-docs: A gulp plugin for generating documentation in Markdown format for React components based on their propTypes. The plugin uses react-docgen to extract component prop information, and then render the Markdown using Handlebars.

AdRoll uses large-scale machine learning to bid intelligently in internet advertising auctions. In this post, we explore some of the engineering behind the data pipelines that feed our learning algorithms, in particular our real-time system that constructs features from event streams.

This is the third post in a series of three blog posts about Rollup, AdRoll’s UI component library. This post covers what we learned from building a UI component library.

Create a serverless eventually-consistent global counter system using S3 events, DynamoDB triggers, and Lambda functions implemented in Python: a complete example using the awscli tools.
