Handbook.md shows that long policy documents do not reliably govern agents

https://arxiv.org/static/browse/0.3.4/images/arxiv-logo-fb.png
Researchers created a benchmark of 65 tasks to test language-model agents following long policy documents. The benchmark, which simulates real-world work environments, found most agents failed to consistently follow policies due to issues like overriding rules and losing details over time.

Apple should be ashamed of its hostile App Store rating system

https://lapcatsoftware.com/articles/2026/7/14-images/2.png
I could have terminated the title of this blog post with “App Store” but wanted to talk about something specific that came up for me today: App Store user ratings and reviews. This subject is related to yesterday’s blog post No, you curate the App Store. Despite the fact that Apple employees privately review every version of every app before developers can publish to the App Store, supposedly ...

The DuckDB build outperforms the SQLite build in all scenarios, making it the recommended choice for self-hosting the full OTel stack on a small server.

User Interfaces of the Demo Scene

https://www.datagubbe.se/scenegui/p/elitesinuesproducer-menu.png
The demo scene, a digital art subculture, has a long history of creating its own tools, including assemblers, trackers, and other software, often with unique and quirky user interfaces. These tools, such as Seka, AsmOne, and ProTracker, were used to create demos, music, and graphics, and often featured peculiar designs and features that were characteristic of the scene.

SQLite in Production: Optimizing WAL Mode, Concurrency, and VFS Layers

https://micrologics.org/ml-logo.PNG
To achieve ultra-low latency in SQLite, configure WAL mode, manage busy handlers, and leverage custom Virtual File System (VFS) layers, and pair WAL mode with the NORMAL pragma to prevent disk synchronization bottlenecks. Properly configuring SQLite with WAL mode, memory mapping, and transaction boundaries can handle hundreds of concurrent requests and millions of queries per day on a modest ...

PostgreSQL's MVCC is bad. So is everyone else's

https://boringsql.com/og-images/mvcc-is-bad-compared-to-what-og.jpg
PostgreSQL's MVCC design is criticized for causing write amplification, bloated tables, and delayed cleanup, but its critics often fail to consider the trade-offs and costs of alternative designs. Other databases, such as Oracle, MySQL, and MongoDB, have their own versions of MVCC that address some of the same issues but introduce new problems, highlighting the complexity and trade-offs ...
