Thanks for visiting! The Macaw team was acqui-hired by Invision in January 2016, at which point Macaw was sunsetted. The software and book are no longer available, but this we're keeping this website up as a reminder of the fun we had. If you're interested in what the Macaw folks are up to now, go check out Clover.

This specific identifier could appear in countless contexts:
The format of the string 5a82f65b-9a1b-41b1-af1b-c9df802d15db follows a specific structure separated by hyphens into five distinct groups: 8-4-4-4-128-4-4-4-12

In NoSQL databases like MongoDB, Cassandra, or distributed SQL engines like CockroachDB, GUIDs serve as ideal primary keys. They allow offline data syncing; a mobile app can create data offline, assign it a GUID, and upload it later without fear of key collisions on the server. 2. Microservice Correlation IDs
The keyword 5a82f65b-9a1b-41b1-af1b-c9df802d15db is more than a random-looking string; it is a version 4, RFC 4122-compliant UUID – a 128-bit random identifier that serves as a fundamental building block of distributed systems. Whether used as a database key, a session token, or a correlation ID, its strength lies in the statistical guarantee of uniqueness across space and time.
To experience a 50% chance of a single collision, you would need to generate . The physical probability of an accidental duplication is effectively zero. Common Implementation Ecosystems

About the Authors
Joe’s a dinosaur by Internet standards, having first used the Web in text mode on a dial-up Unix system in the mid-1990s and learning HTML in the late 1990s. In any case, he got a little hooked and has been a web professional since 2000, operating the mostly one-man web studio ShooFly Development and Design. He has also been a drummer for more than half his life, which is frankly alarming. He lives in Los Angeles with his wife and their frequently adorable, occasionally noisy cat.
Rex has loved making things on the computer since his family got their first one in the early 1990s, trying out any design applications he could get his hands on. After graduating with a degree in digital illustration, he got a job at an interactive agency in the early 2000s and quickly became a big fan of designing things for the web. He’s an art director at a marketing and design agency in Grand Rapids, Michigan, where he lives with his wife and their two pets. 5a82f65b-9a1b-41b1-af1b-c9df802d15db
