Notes on the latest in tech, .NET, Azure and applied AI — what I'm learning and shipping in production.
Implement Transactional Outbox and Inbox with .NET 10 and PostgreSQL 18: atomic writes, at-least-once delivery, retries, and consumer effects deduplicated in the same transaction.
Build a retry-safe .NET 10 API with Idempotency-Key, request fingerprints, SQLite, exact response replay, concurrency handling, and 409/422 responses.
Build a .NET 10 API that negotiates culture per request and localizes validation and domain exceptions with Accept-Language, IStringLocalizer, and .resx resources.
We built an application that generates reports in the background and streams their progress from a .NET 10 Minimal API to React using Server-Sent Events, with typed events, automatic reconnection, and resumption using Last-Event-ID.
ECMAScript 2026 introduces improvements for Maps, Iterators, errors, bytes, numeric operations, asynchronous sources, and JSON without precision loss. Several already work in current runtimes, but support is not yet consistent.
Claude Opus 5 combines a one-million-token context window, five effort levels, and greater autonomy. I look at what changes and where it may fit alongside Sol, Terra, and Luna.
TypeScript 7 moves the compiler to Go. A practical guide to migrating Node services while embedded tooling still depends on TypeScript 6.
A functional .NET 10 FluentValidation tutorial covering reusable rules, conditional PATCH validation, ProblemDetails, Dependency Injection, and black-box tests.
A step-by-step tutorial for implementing CQRS in .NET without MediatR: commands, queries, a dispatcher, automatic handler registration, and a complete POST/GET feature.
A hands-on, first-week take on OpenAI's GPT-5.6 family — Sol, Terra and Luna. Why Terra, not Sol, is the model that actually matters for a solo dev, and what the new native-subagent Ultra mode means once you actually try it.
I migrated albertorrg.dev from Astro 6 to Astro 7 in a few hours. Here's what really changed: Vite 8 with Rolldown (the Rust bundler), a migration without touching the config, my real build times, and the rock I tripped over — with code examples.
I sat down to really try Angular 22. A practical, personal rundown of what stood out most: OnPush by default, httpResource, Signal Forms, @Service, injectAsync, debounced and zoneless — with code examples.
Anthropic says it disabled Fable 5 and Mythos 5 for all customers after a US export-control directive ordered access suspended for foreign nationals, citing national security concerns around a potential jailbreak.
A practical breakdown of .NET 11 Preview 5: C# closed hierarchies and unions, LINQ FullJoin, JSON Lines, MCP server templates, Blazor SSR improvements, and EF Core 11 tooling.
Complete guide to the View Transitions API: transitions between MPA pages and between SPA states with CSS. Mental model, shared element, examples in vanilla, React and Angular, common real-world mistakes, and how to debug them.
Anthropic launched Claude Fable 5, the first broadly available Mythos-class model, alongside Claude Mythos 5 for trusted access.
Google released Gemma 4 12B Unified, an open-weight encoder-free multimodal model designed to run locally on laptops, with support for text, images, audio, video, and agentic workflows.
Microsoft Build 2026 introduced a full agent stack: Microsoft IQ, Agent 365, Scout, OpenClaw on Windows, Foundry, MAI models, Rayfin, HorizonDB, and more. This recap explains what it means for developers.
While the .NET community looks ahead to .NET 11 and C# 15, C# 14 already brings practical improvements worth knowing: extension members, null-conditional assignment, field-backed properties, spans, and more.
