Fine-Tuning YOLO to Watch Soccer Matches
Fine-tuning pre-trained YOLO models for specialized object detection tasks requires significantly less data and training time than building from scratch. Using a soccer dataset with 7,010 training images, the author demonstrates how to adapt a COCO-trained YOLOv11 model to detect balls, players, referees, and goalkeepers with 88% mAP50 accuracy. The process involves using Ultralytics tools for training, monitoring key metrics like loss values and mAP50, and converting the final PyTorch model to ONNX format for deployment in Elixir applications. The fine-tuned model shows superior contextual understanding compared to generic models, focusing on field action while filtering out background spectators.

I'm switching languages again...
A developer shares their experience learning Elixir, highlighting two key features that attracted them to the language: pattern matching in function definitions and the 'with' construct for error handling. They demonstrate how Elixir's pattern matching allows for declarative programming by defining multiple function clauses that match different input patterns, eliminating the need for complex if-else chains. The 'with' construct is praised for its ability to chain operations cleanly while handling errors gracefully, similar to promise chains but with pattern matching capabilities. The developer compares Elixir favorably to Rust and Go, noting that while Rust has pattern matching, it lacks function overloading, and that Rust becomes inconvenient at higher complexity levels.

Elixir → JavaScript Porting Initiative
Hologram needs community help porting 171 Erlang standard library functions to JavaScript to enable Elixir execution in browsers. The project is 34% complete for Phase 1, which focuses on full-stack web applications. Contributors don't need deep Erlang knowledge - just basic JavaScript and Elixir skills to follow existing patterns. Tasks range from 15 minutes to a few hours, and AI tools are encouraged. Each ported function unlocks multiple Elixir stdlib functions, creating a multiplier effect for the community.

Less Glue, More Product: Why Elixir Shrinks Architectural Complexity
Elixir offers significant advantages for solo developers and small teams building backend services by reducing architectural complexity. The BEAM virtual machine enables features like caching, background jobs, and workflow orchestration within a single application, eliminating the need for external queues, job systems, or orchestration services that other frameworks require early on. Phoenix provides these capabilities out of the box, while frameworks like Ash can generate REST or GraphQL APIs through declarative modules. This approach allows developers to focus on building product features rather than managing infrastructure complexity.

The Most Admired Web Framework
Phoenix is the most admired web framework, heavily inspired by Rails and known for LiveView, which enables dynamic updates without HTTP requests through WebSocket connections. This architecture allows for server-initiated changes and data streaming to all users. Phoenix leverages Elixir, designed for resilience and concurrency, with a unique process-based architecture in the BEAM VM. Elixir applications demonstrate high loads before showing latency spikes, unlike Go. However, it excels in use cases like chat applications and real-time updates where websocket connections are crucial.

Modern and Flexible Accounting
A solo founder shares their three-month journey building WorkBill, a double-entry accounting platform for small businesses. The tech stack centers on Elixir/Phoenix backend with InertiaJS bridging to a React frontend using shadcn/ui components. The platform features a flexible general ledger based on BeanCount's nested account model, allowing complex transaction representation without rigid categories. Key technical choices include Postgres for data storage, Oban for background jobs, BAML for LLM-powered reconciliation, and Reducto for PDF parsing. The nested account structure enables users to track finances flexibly even without explicit feature support, with invoicing and PDF generation via Typst planned next.

Zoi: A Schema Validation Library for Elixir Inspired by Zod
Zoi is a new Elixir schema validation library inspired by TypeScript's Zod, bringing similar ergonomics to the Elixir ecosystem. It enables declarative schema definition, runtime validation, typespec inference for Dialyzer, and automatic JSON Schema generation for OpenAPI documentation. The library integrates with Phoenix controllers and LiveView forms, supports metadata-driven documentation, and complements existing tools like Ecto and NimbleOptions while maintaining validation and documentation in sync.

State of Elixir 2025
Over 1,000 Elixir developers participated in the 2025 State of Elixir survey, revealing a senior-heavy community (median 13+ years experience) that values concurrency, fault tolerance, and developer joy. Phoenix and LiveView dominate the ecosystem, with most teams running small deployments (1-5 nodes) in compact teams. While Elixir delivers strong business impact through reliability and faster delivery, hiring remains challenging. The community prioritizes LSP stability, type system completion, and native tooling over new features, with particular gaps in UI components and AI/ML integration.

The Great Connection Pool Meltdown
Tuist's caching server experienced cascading failures when their cloud provider's network issues caused connection pool exhaustion. Thousands of failed S3 requests queued up, consuming memory until the server crashed repeatedly. The team implemented fail-fast queue configurations and migrated to a new provider (Render.com), resolving the stability issues. Key lessons include the importance of monitoring, trusting initial diagnoses, and designing systems that gracefully handle failures rather than cascading them.

Elixir is not owned by Big Tech
Elixir is a programming language not heavily influenced by large tech corporations, making it stable and community-driven. The language benefits from contributions by various companies and individuals, and its ecosystem is supported by consultancy firms like Dashbit. Ericsson plays a significant role due to its involvement with the Erlang/OTP foundation, which underpins Elixir. This structure ensures Elixir remains productive and satisfying without overreliance on megacorporations.
