The AI Index 2019 Report takes an interdisciplinary approach by design, analyzing and distilling patterns about AI’s broad global impact on everything from national economies to job growth, research and public perception. We’re excited to release the AI Index 2019 Report, one of the most comprehensive studies about AI to date. Because AI touches so many aspects of society, the Index takes an interdisciplinary approach by design, analyzing and distilling patterns about AI’s broad global impact on everything from national economies to job growth, research and public perception.

If you haven’t heard of WebAssembly yet, then you will soon. It’s one of the industry’s best-kept secrets, but it’s everywhere. It’s supported by all the major browsers, and it’s coming to the server-side, too. It’s fast. It’s being used for gaming. It’s an open standard from the World Wide Web Consortium (W3C), the main international standards organization for the web. Going back about ten years, there was a growing recognition that the widely-used JavaScript wasn’t fast enough for many purposes. JavaScript was undoubtedly successful and convenient. It ran in any browser and enabled the type of dynamic web pages that we take for granted today.

Uber leverages real-time analytics on aggregate data to improve the user experience across our products, from fighting fraudulent behavior on Uber Eats to forecasting demand on our platform. As Uber’s operations became more complex and we offered additional features and services through our platform, we needed a way to generate more timely analytics on our aggregated marketplace data to better understand how our products were being used. Specifically, we needed our Big Data stack to support cross-table queries as well as nested queries, both requirements that would enable us to write more flexible ad hoc queries to keep up with the growth of our business.

Many moons ago, I was working at the New York Times and created a library called Store, which was “a Java library for effortless, reactive data loading.” We built Store using RxJava and patterns adopted from Guava’s Cache implementation. Today’s app users expect data updates to flow in and out of the UI without having to do things like pulling to refresh or navigating back and forth between screens.

Machine learning is at the heart of everything we do at Spotify. Especially on Spotify Home, where it enables us to personalize the user experience and provide billions of fans the opportunity to enjoy and be inspired by the artists on our platform. This is what makes Spotify unique. Across our engineering community, we are working to unite autonomous teams and empower them to be more efficient by establishing best practices for tools and methods. Our recent adoption of a standardized machine learning infrastructure provides our engineers with the environment and tools that enable them to quickly create and iterate on models. We call it our ‘Paved Road’ approach, which includes utilizing services from TensorFlow, Kubeflow, and the Google Cloud Platform.

I’ve been pretty invested in helping organizations with their cloud-native journeys for the last five years. Modernizing and improving a team (and eventually an organization’s) velocity to deliver software-based technology is heavily influenced by it’s people, process and eventual technology decisions. A microservices approach may be appropriate when the culmination of an application’s architecture has become a bottleneck (as a result of the various people/process/tech factors) for making changes and “going faster”, but it’s not the only approach.

In this blog post we’ll show you how we migrated a critical Postgres database with 18Tb of data from Amazon RDS (Relational Database Service) to Amazon Aurora, with minimal downtime. To do so, we’ll discuss our experience at Codacy. We chose Amazon’sAuroradatabase as a solution for a few key reasons including: 1) automatic storage growth (up to 64Tb); 2) ease of migration from RDS and 3) performance benefits. Although, Aurora’s official docs only claimed up to a3x increase in throughput performanceover stock PostgreSQL 9.6, testimonials claimed thatperformance increased 12x, just by doing the migration to Aurora.

A number of years back, there was a great deal of excitement about using viruses to target cancer. A number of viruses explode the cells that they’ve infected in order to spread to new ones. Engineering those viruses so that they could only grow in cancer cells would seem to provide a way of selectively killing these cells.

How does a Prometheus Histogram work? We looked previously at thecounter, gauge, and summary, how does the Prometheus histogram work? The histogram has several similarities to the summary. A histogram is a combination of various counters. Like summary metrics, histogram metrics are used to track the size of events, usually how long they take, via their observe method. There’s usually also the exact utilities to make it easy to time things as there are for summarys.

Service Mesh is the communication layer in a microservice setup. All requests, to and from each of the services go through the mesh. Also known as an infrastructure layer in a microservices setup, the service mesh makes communication between services reliable and secure. Each service has its own proxy service (sidecars) and all the proxy services together form the service mesh. The side cars handle communication between services, which means all the traffic goes through the mesh and this transparent layer can now control how services interact.
