   How I built Timeframe, our family e-paper dashboard

   A decade-long personal project building a family e-paper dashboard called Timeframe, evolving from a Magic Mirror LCD to jailbroken Kindles, then Visionect e-paper displays, and finally a 25.3" Boox Mira Pro with real-time updates. The system aggregates calendar, weather, and smart home data, with Home Assistant now serving as the primary data source. Key architectural decisions include removing the database and Redis from the Rails backend, using file-store caching, and a status-indicator design philosophy that only surfaces actionable information. The project remains a work-in-progress with hardware cost and distribution challenges still to solve.

   Claude Code: Production ready code in a two-week sprint

   Thoughtbot demonstrates how to use Claude Code to build production-quality Rails applications through disciplined practices. The approach emphasizes small, controlled tasks, comprehensive test coverage, frequent commits with human review, and maintaining context through documentation. During a two-week sprint for TellaDraft, they integrated multiple AI services (ElevenLabs, WhisperAI, ChatGPT) while ensuring code quality through constant validation, proper testing patterns, and avoiding the pitfalls of "vibe coding" where AI generates unreviewed code.

   Ruby 4 & Rails 8: A Multi-Front Acceleration of the Ruby Ecosystem

   Ruby and Rails are undergoing a coordinated multi-front evolution. Ruby 4 brings incremental VM improvements, maturing Ractors for real CPU-bound parallelism, pluggable garbage collectors for workload-specific memory management, and a leaner modular standard library. On the Rails side, Rails 8.1 introduces Solid Queue for database-backed background jobs (reducing Redis dependency), a built-in authentication generator, improved parallel gem resource management, and deeper PostgreSQL 18 integration. The author also highlights two new libraries—ruby-libgd and libgd-gis—that bring native graphics and GIS capabilities to Ruby. The piece concludes with a call for Western and LATAM developer communities to re-engage with Ruby's accelerating evolution.

   Rails Meets PostgreSQL 18

   PostgreSQL 18 introduces protocol 3.2 with extended cancel keys, removes UNLOGGED partitioned tables, and adds virtual generated columns. Rails 8.1 adapts through defensive adapter patches, requires pg gem ≥1.6 for compatibility, and adds support for virtual generated columns with `stored: false`. The pg_stat_statements extension receives improvements for better query profiling. Rails maintains forward compatibility through runtime capability detection rather than version ceilings, demonstrating mature ecosystem collaboration between PostgreSQL core, the pg gem, and Rails adapters.
