Towards true continuous integration – Netflix TechBlog – Medium

For the past 8 years, Netflix has been building and evolving a robust microservice architecture in AWS. Throughout this evolution, we learned how to build reliable, performant services in AWS. Our microservice architecture decouples engineering teams from each other, allowing them to build, test and deploy their services as often as they want. This flexibility enables teams to maximize their delivery velocity. Velocity and reliability are paramount design considerations for any solution at Netflix. As supported by our architecture, microservices…

Engineering Stability in Migrations: Moving to Immutable Collections in Uber’s Android Apps

Making models for Android apps frequently involves writing a lot of boilerplate code by hand. This process can be time-consuming, error-prone, and lead to hard-to-spot bugs when done incorrectly. To address this at Uber, we built a custom stack to generate AutoValue models and network clients from Thrift Specs. In this article, we explore how models in Uber’s Android apps ended up being mutable despite using AutoValue; we illustrate some of the pitfalls of mutability and detail a class of…

Enhancing Pinner security with login emails and revoking sessions

Amine Kamel, Emanuele Cesena & Eric Zhang | Pinterest engineers, Security The Pinterest Security team is tasked with keeping the accounts of more than 175 million people safe and secure. We recently added another layer of protection to secure Pinners’ accounts. Now, logging in from a new device or location will trigger an email notification, and all active sessions can be viewed and revoked from the user settings page. Here we’ll describe the system architecture powering the new features. New…

A Modest Proposal to Save California $200 Million

In order to forestall a lot of hate mail, the following blog is written in the tradition of eighteenth-century satirist Jonathan Swift’s essay, “A Modest Proposal.”  It is not meant to be taken seriously.  With that out of the way, I have a modest proposal to save the good citizens of California over $200 million.  That is the estimated cost of a suicide-deterrent net project that is going to be installed on the Golden Gate Bridge, according to a recent…

What Makes a Good Fiducial?

Accountants may have a fiduciary responsibility, but that really has nothing to do with PC board assembly. Change the “ry” to a “ls”, however, and you get fiducials, which does have something to do with PCB assembly. A fiducial is essentially an alignment mark for surface mount assembly machines. High volume assembly requires them to ensure accurate registration and parts placement. Low volume assembly, like we do here at Screaming Circuits, doesn’t necessarily require them. (Some low volume shops do,…

In Praise of Doppler Weather Radars

On Mar. 28, 1920, a series of more than 30 deadly tornadoes made widespread paths of destruction through the central and southern U. S. and caused deaths from Michigan all the way to LaGrange, Georgia.  Shortly before 6 P. M., that southern mill town was struck by a tornado with an estimated Fujita rating of F3, which means its winds probably ranged from 158 to 206 MPH.  After wrecking a cluster of worker’s houses, the town’s main mill and factory…

Presenting an Open Source Toolkit for Lightweight…

By Aasish Pappu, Roi Blanco, and Amanda Stent What’s the first thing you want to know about any kind of text document (like a Yahoo News or Yahoo Sports article)? What it’s about, of course! That means you want to know something about the people, organizations, and locations that are mentioned in the document. Systems that automatically surface this information are called named entity recognition and linking systems. These are one of the most useful components in text analytics as…

Shhhhh… I have a secret… – Kickstarter Engineering

As Kickstarter moves from a monolithic application towards a service oriented architecture, we needed to develop a fast and secure way for a service to programmatically retrieve API tokens, passwords, keys, etc. We are currently managing our containers using Amazon’s ECS (Elastic Container Service), which we like for its seamless scalability of Docker containers, and really wanted to secure the application’s access to sensitive information. We looked at a few tools and even built some ourselves, but we were instantly…

Etsy’s Debriefing Facilitation Guide for Blameless Postmortems

In 2012, I wrote a post for the Code As Craft blog about how we approach learning from accidents and mistakes at Etsy. I wrote about the perspectives and concepts behind what is known (in the world of Systems Safety and Human Factors) as the New View on “human error.” I also wrote about what it means for an organization to take a different approach, philosophically, to learn from accidents, and that Etsy was such an organization. That post’s purpose…
