Here's a recording. The title bar changes to match the colour of the terminal, which is more subtle than changing the background like I do in the terminal, but still provides a good context signal.

I made a small but nice improvement to my terminal recently, where each project (git repo) now has its own background colour in the terminal. It's an effective context signal telling me which project I’m currently in as I'm bouncing around terminal windows. andrew-jones.com/blog/per-pro...

In this week's newsletter I talk about the need to move from data replication to data publication. Also 4 interesting links, including articles on turning around a platform team, feedback loops, leadership, and an SQL-based game. #dataBS andrew-jones.com/newsletter/2...
Diagram showing the steps involved in data replication, which are 1. service, 2. database, 3. data warehouse with all data replicated, 4. transformation, 5. value. In contrast, another diagram showing data publication, which are 1. service, 2. data warehouse (with fewer tables), 3. value.

In this week's newsletter I write about how you deliver data products with data contracts. There's also links to a nice article on the importance of semantic integrity and capturing those in a data contract, and the revolution of providing data platforms with golden paths. a-j.io/n250131
Diagram showing the data contract describing the data product, which in this case is a table.

Recently the team at Notion published a great post titled "A brief history of Notion’s data catalog". While the focus is on the data catalog, it’s really a lesson in metadata management. And while they don’t call it a data contract, that's basically what it is.

I got my first a “posts you might have missed” style email from Threads today, but I don’t think they chose the best one to highlight…
