At Netflix, we want to entertain the world through creating engaging content and helping members discover the titles they will love. Key to that is understanding causal effects that connect changes we make in the product to indicators of member joy. To measure causal effects we rely heavily on AB testing, but we also leverage quasi-experimentation in cases where AB testing is limited. Many scienti

What to expect when monitoring memory usage for modern Go applications. EDIT (2020.12.13): From Go 1.16, Go on Linux moves back to using MADV_DONTNEED when releasing memory. However, this blog post still applies in terms of how to monitor memory consumption, although we should see less memory cached by Go runtime. See this issue . TL;DR: Applications build with Go 1.12+ reports higher RSS memory u
In its latest release, Playwright has gained a new feature called Playwright Test. This newly added test runner for Playwright enables the smoothest testing experience in Next.js applications I have ever seen. Once set up, it allows testing with real browsers across multiple device sizes. We’ll be able to mock requests made by the frontend. And, we’ll be able to mock the backend’s requests as well

In this article, we will compare one apple (IntelliJ Rust) to one orange (rust-analyzer) to reach general and sweeping conclusions. Specifically, I want to present a case study supporting the following claim: For me, this is an unusual claim to argue: I always thought exactly the opposite, but I am not so sure now. I came to Rust from C++. I was of the opinion that this is a brilliant low-level la

For those interested in the JIT in PHP 8, I did some benchmarks for you in real-world web application scenario. Be aware that these benchmarks don't say anything about whether the JIT is useful or not, they only show whether it can improve the performance of your average web application, or not. # Setup Let's set the scene first. These benchmarks were run on my local machine. As so, they don't say
Docker gives developers the ability to package all of their applications inside of containers. These containers can run on any machine that has Docker installed and the application will be identical. This is a great way to run a clone of a codebase on multiple systems and you can be sure that they are all going to be the same. CI/CD workflows and DevOps testing environments are significantly bette
