Honest software development: code that lasts and stays with you.
El concepto de Agent OS pasó del slide al despliegue en 2025. Seis meses en producción dejan patrones visibles: qué arquitecturas funcionan, dónde se rompe el modelo y qué aporta frente a correr agentes sobre pila existente.
A year after GraphRAG left the lab, one statistic holds: it works where corporate information has dense relational structure, fails where there are only loose documents. Patterns, ingestion costs, and architectural decisions that have survived a year of real deployment.
The AI tool stack a developer uses in 2026 looks nothing like it did eighteen months ago. Agentic editors, review tools, terminal agents, and test assistants have settled into recognizable roles. A practical guide by category.
Twenty months after the initial announcement, Model Context Protocol went from curiosity to de-facto standard among agent clients and servers. What is available, which servers are worth it, which problems remain open, and how it compares to earlier protocol maps.
Con 1.34 liberado en agosto de 2025 y el ciclo de 1.35 en su última fase de congelación de funciones, qué llegará estable, qué quedará en beta, qué nos interesa a quienes mantenemos clústeres pequeños o medianos y qué podemos ignorar sin culpa hasta el siguiente ciclo.
La integración de WebAssembly dentro de containerd como tiempo de ejecución alternativo ha madurado. Ya es posible desplegar cargas mixtas Linux y Wasm en el mismo clúster de Kubernetes con argumentos operativos sólidos. Cuándo compensa y cuándo no.
Model Context Protocol turns ten months old since Anthropic's announcement, and it is no longer just a proposal: hundreds of servers, cross-vendor implementations and a public registry now back it. A look at what has worked, what is still weak, and why 2025 marks the shift from curiosity to basic infrastructure.
Distributed SQL databases have moved from promise to production reality. YugabyteDB and CockroachDB lead the segment from different angles. Choosing between them demands understanding what each design compromises and what horizontal scaling costs in practice.
Qwik has spent two years promising apps that start instantly because, instead of hydrating, they resume execution serialized on the server. With the 1.x series settled and real cases published, this guide checks whether resumability is worth the learning curve and which products benefit most from that client-side JavaScript saving.
TypeScript 5.5 llegó con inferencia de predicados, tipos de expresiones regulares estrictos y mejoras de declaraciones aisladas. Un año de uso real para separar lo que cambia el código diario de lo que es novedad cosmética, y cuándo conviene actualizar.
Polars lleva dos años pidiendo relevo a pandas. Con Polars 1.x estable y una comunidad creciente, toca revisar dónde de verdad compensa migrar, dónde pandas sigue ganando y cómo convivir entre ambos sin pagar dos veces.
A year after chat stopped being the only acceptable way to talk to an agent, UI patterns built specifically for agent tasks are emerging. I go through the ones starting to stick and the ones that are just cycle fashion.
Kubernetes 1.33 (Octarine) lands April 23. In-place pod resize moves to beta and ships on by default, sidecar containers finally reach GA, and several endpoint and security deprecations arrive that operators should review before upgrading from 1.32.
The AI features Figma has rolled out since Config 2024 are changing how product design teams work. A look at what each feature delivers, what remains human work, and which habits are taking hold across teams.
MariaDB 11.7 (November 2024) adds native vector search with an HNSW index, JSON improvements via JSON_OBJECT_AGG, and 5-15% faster read workloads versus 11.5. Against MySQL 8, the edge is not depending on HeatWave for embeddings; against PostgreSQL, it still trails on JSON depth and data types.
Rust 1.75 stabilises async fn in traits, return-position impl Trait, and several byte-level pointer methods such as byte_add. Rust 1.76 adds an ABI guarantee between char and u32, plus convenience utilities like Result::inspect and type_name_of_val. Two releases that add real ergonomics without flashy gestures.
DuckDB es el motor analítico embebido que ha cambiado el panorama. Lee Parquet y CSV directamente, vectoriza la ejecución y cabe dentro de tu proceso Python. Un repaso a cuándo sustituye de verdad a un data warehouse.
Figma Dev Mode is the developer-facing view inside a Figma file: it generates ready CSS, exposes exact measurements, maps variables to tokens, and, with Code Connect, links each component to the real codebase snippet. It solves most of the design-to-code handoff friction, but it does not replace human judgment on accessibility, performance, or responsive behavior.
GitHub Copilot Workspace, in technical preview since April 2024, proposes task-oriented development: describe the problem in a GitHub issue and the AI reads the codebase, generates an editable multi-file plan, and implements it. It competes with Cursor Composer, though with more latency; its edge is native integration with PRs, issues, and GitHub history.
vLLM serves language models on GPU using PagedAttention and continuous batching, two techniques that multiply throughput compared with a naive server. It exposes an OpenAI-compatible API, so migrating an existing application only requires changing the base URL and deploying the right binary.
Tras dos años de RAG en producción, patrones claros emergen: chunking inteligente, hybrid search, re-ranking, evaluación continua. Qué evitar.
Qwik bets on resumability instead of hydration: the server serialises state into the HTML itself and the client downloads nothing until the user actually interacts, so the initial application bundle is zero kilobytes. In Lighthouse that means a TTI below 0.5 seconds, though it does not pay off for teams already invested in React or for apps with heavy realtime collaborative state.
OpenAI's Assistants API offers persistent threads, sandboxed code execution, and managed document search, but OpenAI is shutting it down completely on August 26, 2026 in favor of the Responses API. We look at when it used to pay off against Chat Completions with your own infrastructure, and what to do if your project still depends on it.
Litestream is an open-source tool that replicates a SQLite database to an S3 bucket in near real time by reading the WAL SQLite already writes. It offers point-in-time recovery, overhead of only 1 to 3% CPU, and replaces the need for a separate database server in small apps.
Kubernetes 1.31 brings no fireworks, but it closes old debts: AppArmor reaches GA, native sidecars now run enabled by default on their way to stable in 1.33, and DRA moves through alpha toward beta. A practical review from the perspective of someone operating clusters in production.
App Router went stable in Next.js 13.4 (May 2023), bringing Server Components, layered caching, and Server Actions, but it demands rethinking the application's mental model. Migrating from Pages Router pays off for new projects and read-only routes; for large applications, the realistic path is incremental, route by route, over several months.
containerd is the runtime that runs containers in most modern Kubernetes clusters, and almost nobody notices. It manages the full container lifecycle: pulling the image, starting it, networking, and mounting the filesystem. It became the default runtime after Kubernetes 1.24 removed dockershim in May 2022.
A practical guide for development teams who need to meet WCAG 2.1 without turning accessibility into an endless project. Three layers, a set of proven tools, and 2-3 months of disciplined work are enough for most teams.
