   Redka: Redis re-implemented with SQL

   Redka is a Redis-compatible server and Go module that reimplements Redis functionality using SQL databases (SQLite or PostgreSQL) as the backend. It supports five core Redis data types (strings, lists, sets, sorted sets, hashes) and offers both standalone server and embedded library usage. While not matching Redis performance, Redka handles tens of thousands of operations per second and provides benefits like SQL introspection, embedded caching for Go apps, and simplified testing environments.

   The Story of Max, a Real Programmer

   A developer reflects on rewriting a 15-year-old PHP image hosting application in Go, only to discover that the original simple PHP code was superior despite being written by a teenager. The original 185-line PHP script proved more maintainable and elegant than the 305-line Go replacement, highlighting how simplicity often trumps sophisticated engineering. The story explores the value of straightforward, single-file solutions over complex, structured codebases, ultimately deciding to keep the original PHP version running.

   So I Quit $200k Job To Write A Framework

   A developer quit their $200k job to build a new web framework in Go that combines SPA-like user experience with MPA simplicity. The framework uses a stateful server architecture with an ultra-thin client, eliminating the need for traditional APIs by handling UI events on the server and streaming HTML updates. Key features include server-driven components, real-time synchronization via rolling HTTP requests, type-safe routing, and a novel component architecture separating state (Beam), containers (Node), and templates (Fragment). The framework aims to reduce developer burnout and hosting costs while maintaining modern UX, targeting a paid license model with early access available.

   zserge/pennybase: Poor man's Backend-as-a-Service (BaaS), similar to Firebase/Supabase/Pocketbase

   Pennybase is a minimalist Backend-as-a-Service implementation in under 1000 lines of Go code with zero external dependencies. It provides file-based CSV storage, REST API endpoints, authentication with session cookies, role-based access control, real-time updates via Server-Sent Events, and template rendering. Data is stored in human-readable CSV files with append-only versioning, making it suitable for simple applications that need basic backend functionality without the complexity of larger solutions like Firebase or Supabase.

   Implementing Enum Types in Go

   Go doesn't have built-in enum types, but you can implement enum-like functionality using custom types with constants. The article demonstrates how to create type-safe enums using custom types, the iota constant generator for auto-incrementing values, and adding methods like Name(), String(), Values(), and ValueOf() to make enums more feature-rich and similar to those in other languages like Java.

    Golang vs Rust: Which Language Wins for Backend in 2025?

    Rust outperforms Go by at least 30% in runtime speed and handles 60,000 vs 40,000 requests per second, but Go compiles faster and offers easier team onboarding. Go excels in microservices and cloud infrastructure with lightweight goroutines, while Rust dominates performance-critical systems through its ownership model that prevents memory leaks. The choice depends on whether teams prioritize development speed and simplicity (Go) or maximum performance and memory safety (Rust). Many organizations use both strategically within the same systems.

    Scaling multi-tenant Go applications

    Hierarchical partition keys in Azure Cosmos DB solve multi-tenant scaling challenges by enabling three-level partitioning (tenant, user, session) instead of single-level partitioning. This approach eliminates hot partitions, improves query efficiency, and provides better resource distribution for tenants of varying sizes. The Go SDK implementation demonstrates how to create containers with hierarchical partition keys and execute targeted queries that avoid expensive cross-partition operations, resulting in better performance and lower costs for SaaS applications.
