REARCHITECTING: REDIS TO SQLITE

Wafris, an open-source web application firewall company, transitioned its Rails middleware client from using Redis to SQLite as the backing datastore.

THE PYTHON PACKAGE INDEX SHOULD GET RID OF ITS TRAINING WHEELS

The Python Package Index (PyPI) of prebuilt binaries has grown exponentially, leading to massive storage and bandwidth costs. This author proposes a three-pronged solution: 1) leverage advancements in systems programming to create repeatable builds, allowing for easier reconstruction of binaries, 2) make prebuilt binaries optional, reducing PyPI's storage burden, and 3) establish secondary caches for popular packages to offload bandwidth pressure.

CONWAY'S LAW: THE HIDDEN FORCE SHAPING YOUR SOFTWARE ARCHITECTURE

Conway's Law states that software architecture often reflects the communication structure of the organization that created it. This means teams tend to create software components aligned with their own structure, even if a different architecture would be more efficient. Engineering managers and developers should focus on designing their teams well, which inherently leads to better software architecture.
