To me it seems obvious that code should be stored in a database rather than a hierarchical, text-based format.

Multiply Went from Datomic to XTDB to Rama
(redplanetlabs.com)
"With databases, the conversation always started with ‘what are we able to do?’. I rarely find myself asking what Rama is able to support, and rather ‘how?’. The requirements of the application dictate how we utilise the platform, not the other way around. Rama as a tool allows us to think product first, while still delivering highly optimised and scalable features for specific use cases, something that would not have been possible without a much larger team.”

Apache Iceberg now supports geospatial data types natively
(wherobots.com)
Geospatial solutions were thought of as “special”, because what modernized the data ecosystem of today, left geospatial data mostly behind. This changes today. Thanks to the efforts of the Apache Iceberg and Parquet communities, we are excited to share that both Iceberg and Parquet now support geometry and geography (collectively the GEO) data types.

Apple Passwords is hostile to backups
(lapcatsoftware.com)
In my view, a useful backup system must be (1) chronological, (2) granular, and (3) redundant. A chronological backup system includes multiple historical snapshots of your data, allowing you to recover not only the latest version of your data but also past data that has been deleted or edited. A granular backup system allows you to selectively recover specific fragments of data from your backup without disturbing, deleting, or corrupting the rest of your current data.

Data is being increasingly treated like code has been treated for decades. For many use-cases it isn't enough to know "What is the current value?" but also "What was the value previously?", "Who last changed the value?", and "Why did they change the value?"
