Today's children are exposed to technology from a very young age, and on many occasions, 2-year-olds seem to understand the iPad better than adults. Is this enough to encourage and influence them to pursue a career in STEM (science, technology, engineering and mathematics)?

Large scale applications are ubiquitous in today's world, processing hundreds of billions of events and producing thousands of metrics. Sifting through these metrics to surface actionable insights without using scientific methods can be challenging. In this blog post, we explore an introduction to the realm of predictive analytics in the context of anomaly detection.

A recent eBay Tech Blog article¹ presented the Unified AI platform called Krylov. In this article, we show how Krylov users interact with the platform to build and manage powerful workflows in a pythonic and efficient way.

As we move further into 2020, it’s worth reviewing a selection of key eBay Open Source projects released in 2019.

In 2019, eBay prioritized a company-wide initiative, aptly called “Speed,” focused on improving the performance of critical eBay flows across all platforms — iOS, Android, and Web. This article explains the journey and outcomes.

Model-based analysis makes it possible to rigorously test and validate changes prior to deployment. This approach enabled the eBay Network Engineering staff to undertake a project to refactor a large business critical Access Control List, resulting in an 80% reduction in size, without any adverse business impact.

Automated testing helps organizations build better software, faster. Automation can also be used to standardize user experiences or maintain code compliance. With respect to accessibility, automation can be used to bring awareness by helping people with little to no accessibility knowledge easily find, file and fix bugs.

How the AI transformation at eBay was powered by a modern AI platform with a unified and open approach.

eBay introduces the eBay Motors native app, now available for Android and iOS in the U.S. The app was built using cutting-edge tech including machine learning, Backend for Frontend architecture and Flutter, an open source, cross-platform SDK by Google.

eBay’s Buy APIs enable third-party partners to expose eBay inventory on their site.

eBay is taking the friction out of repurchasing a favorite find on eBay with the new Buy Again button.

The less you ask of users, the more inclined they are to complete a form, and faster form filling increases conversion. Browsers provide the autofill feature to help achieve that. In this article, we discuss how to effectively use autofill features on web forms.

Because eBay's item page updates frequently, and because it depends on hundreds of libraries and services, discovering the unknowns and automating testing for all use-case combinations from production calls for a different approach to testing.

eBay enables secure password-less login experiences on the web-based version of eBay with WebAuthn.

To create a trustworthy online marketplace, we need to ensure only authenticated and authorized users gain access to their accounts. Learn how eBay built a secure, easy-to-use, and robust authentication framework using push notifications and leveraged it for 2-step verification.

Learn how eBay's architecture knowledge graph was developed; the benefits eBay has received from it; and the use cases we see now and in the future for this approach.

In this article, we propose a set of better practices, designed by and for eBay ML scientists, for facilitating weaving ML modeling into the cyclical Agile process flow.

eBay technologists recently showed off a distributed transaction protocol called GRIT, for distributed ACID (atomicity, consistency, isolation, durability) transactions across microservices with multiple underlying databases.
