A Five-Step Guide for Conducting Exploratory Data Analysis - Shopify

Mind the platform execution gap

Developer productivity platforms are increasingly recognised as a way to manage the cognitive load of engineering teams and decrease time to market for new features.

SRE & Ops — Reverse debugging at scale

Reverse debugging at scale

Say you receive an email notification that a service is crashing just after your last code change deploys. The crash happens in only 0.1 percent of the servers where it runs. But you’re at a large-scale company, so 0.1 percent equals thousands of servers — and this issue is going to be hard to reproduce. Several […]

Performance — Load Testing with Koi Pond

Load Testing with Koi Pond

Complex systems are difficult to reason about at scale; we often can’t accurately extrapolate system behavior and performance, so we need to derive that data empirically. We use load testing to do just that: find the limits of our systems and weed out bugs at a large scale in a controlled environment. Slack is a…
