https://federicocalo.dev/en/blog Articles about software development, AI, machine learning, architecture and technology en Tue, 14 Jul 2026 12:53:52 GMT info@federicocalo.dev (Federico Calo) info@federicocalo.dev (Federico Calo) https://federicocalo.dev/assets/images/logo.png https://federicocalo.dev/en/blog https://federicocalo.dev/en/blog/inp-cwv-angular-ssr-59-to-88-four-fixes https://federicocalo.dev/en/blog/inp-cwv-angular-ssr-59-to-88-four-fixes Tue, 14 Jul 2026 11:05:00 GMT Federico Calo Original Research Four real interventions that took an Angular SSR home page from a mobile PageSpeed score of 59 to 88: precompute instead of fan-out, PlatformLocation instead of REQUEST at prerender, read/write split with afterNextRender, and a prerender-compatible host-based CSP. With measured numbers and a public repository. https://federicocalo.dev/en/blog/projecthub-poker-retro-be-fe-slice-schema-real-time https://federicocalo.dev/en/blog/projecthub-poker-retro-be-fe-slice-schema-real-time Tue, 14 Jul 2026 11:00:00 GMT Federico Calo Architecture Real-time collaboration is a schema problem, not a WebSocket problem. I document the ProjectHub Poker/Retro vertical (V184/V185) as a real end-to-end slice: eleven Postgres tables, a one-directional phase FSM, STOMP broadcast, server-side anonymity, and a dot-voting budget, with the trade-offs declared at every fork. No code changes. https://federicocalo.dev/en/blog/production-postmortems-flyway-jar-deploy-duplicate-beans https://federicocalo.dev/en/blog/production-postmortems-flyway-jar-deploy-duplicate-beans Tue, 14 Jul 2026 10:50:00 GMT Federico Calo Platform Engineering A comment in an applied Flyway migration breaks the checksum. A non-atomic cp during deploy causes an intermittent NoClassDefFoundError. Two beans with the same simple name crash the boot. Three real incidents, one root cause: violated immutability. https://federicocalo.dev/en/blog/multi-bucket-rate-limiting-bucket4j-postmortem https://federicocalo.dev/en/blog/multi-bucket-rate-limiting-bucket4j-postmortem Tue, 14 Jul 2026 10:45:00 GMT Federico Calo DevSecOps Four separate Bucket4j buckets (API, AI, report download, token) versus one shared number. Routing to the right bucket is where real bugs are born: the postmortem of the CSP-report flood that blocked email verification with 429s. https://federicocalo.dev/en/blog/archunit-clean-architecture-4-layer-diagram-lie https://federicocalo.dev/en/blog/archunit-clean-architecture-4-layer-diagram-lie Tue, 14 Jul 2026 10:40:00 GMT Federico Calo Architettura Software The backend's ArchUnit gate was running zero executed tests, a total false green. How I found it, what I froze with FreezingArchRule (30+4 historical violations), and why a 4-layer diagram without automated enforcement is not an architecture. https://federicocalo.dev/en/blog/production-postmortems-flyway-archunit-jar-race-duplicate-beans https://federicocalo.dev/en/blog/production-postmortems-flyway-archunit-jar-race-duplicate-beans Tue, 14 Jul 2026 10:10:58 GMT Federico Calo Original Research Four real production incidents that all started from a fully green build: a Flyway crash from a removed comment, an ArchUnit gate dead for months, a JAR deploy race condition, a duplicate Spring bean. Root cause, fix, and a reproducible public repository for each. https://federicocalo.dev/en/blog/how-i-build-in-4-hours-gsd-agentic-workflow https://federicocalo.dev/en/blog/how-i-build-in-4-hours-gsd-agentic-workflow Tue, 14 Jul 2026 10:00:00 GMT Federico Calo Claude Code Workflow Claude Code Workflow series. How I built a custom booking module in a little over four hours with GSD and specialized agents: the real per-phase time datum, the trade-offs, and why AI is accompaniment and never the director. Portfolio AI provider: Ollama on-prem. https://federicocalo.dev/en/blog/onpush-signals-default-not-exception-angular-21 https://federicocalo.dev/en/blog/onpush-signals-default-not-exception-angular-21 Tue, 14 Jul 2026 09:52:54 GMT Federico Calo Angular Moderno 1215 out of 1219 components in this portfolio use ChangeDetectionStrategy.OnPush. Why "turn it on when I need it" is a comfortable lie, what immutability discipline actually costs, and when Default is the better call instead. https://federicocalo.dev/en/blog/strict-mode-not-enough-any-typescript-monorepo https://federicocalo.dev/en/blog/strict-mode-not-enough-any-typescript-monorepo Tue, 14 Jul 2026 09:52:54 GMT Federico Calo TypeScript Avanzato strict, strictTemplates, and strictInjectionParameters all on, yet 54 ': any' and 46 'as any' survive across 3884 files. Why strict mode only eliminates accidental errors, not deliberate escape hatches, and what to actually do about the remaining anys. https://federicocalo.dev/en/blog/prerender-vs-server-on-demand-angular-blog-articles https://federicocalo.dev/en/blog/prerender-vs-server-on-demand-angular-blog-articles Tue, 14 Jul 2026 09:52:54 GMT Federico Calo Angular Moderno app.routes.server.ts assigns Prerender to 50 route configurations and Server to 134, deliberately including every article page. Why "prerender everything" stops being safe advice past a certain scale, and the real trade-off between TTFB and build stability. https://federicocalo.dev/en/blog/clean-architecture-spring-boot-template-archunit-gate-that-runs https://federicocalo.dev/en/blog/clean-architecture-spring-boot-template-archunit-gate-that-runs Tue, 14 Jul 2026 09:30:00 GMT Federico Calo Original Research Most Clean Architecture templates ship a green-for-nothing ArchUnit gate that runs zero tests. I extracted a Spring Boot 3.4 template from my production backend, sanitized by hand (no git filter-repo), with JWT, Flyway, and an ArchUnit gate that genuinely executes four rules. Public repo, green build on JDK 21. https://federicocalo.dev/en/blog/ai-on-prem-vs-cloud-privacy-cost-data-sovereignty https://federicocalo.dev/en/blog/ai-on-prem-vs-cloud-privacy-cost-data-sovereignty Tue, 14 Jul 2026 09:24:30 GMT Federico Calo Platform Engineering A B2B comparison with real TCO: on-prem AI with Ollama on a VPS costs zero extra per month, metered cloud bills per token. An honest trade-off on cost, latency, model ceiling, and data sovereignty for decision-makers. https://federicocalo.dev/en/blog/geo-retrofit-benchmark-741-to-0-structural-errors https://federicocalo.dev/en/blog/geo-retrofit-benchmark-741-to-0-structural-errors Tue, 14 Jul 2026 09:14:16 GMT Federico Calo Original Research Most GEO advice is cosmetic. An additive engine (injects, does not rewrite) took 741 structural errors to zero across 194 bilingual articles: 386 missing-FAQ errors closed automatically, 310 missing-citation errors closed only after manual review. https://federicocalo.dev/en/blog/sport-intelligence-benchmark-97k-matches https://federicocalo.dev/en/blog/sport-intelligence-benchmark-97k-matches Tue, 14 Jul 2026 08:51:44 GMT Federico Calo Original Research Why accuracy lies about football predictions and the Brier score does not. The portfolio's Sport Intelligence engine publishes a Brier score of 0.5783 across 97,000 historical matches, with a V2 LightGBM ensemble, isotonic calibration, and a reproducible public repo. https://federicocalo.dev/en/blog/funding-oss-eu-nlnet-sovereign https://federicocalo.dev/en/blog/funding-oss-eu-nlnet-sovereign Sat, 20 Jun 2026 08:00:00 GMT Federico Calo OSS Sustainability Articolo della serie Open Source Sustainability 2027.
