Telemetry that asks first

·1 views

Usage telemetry is genuinely useful. Knowing which commands people actually run, where the errors cluster, whether anyone ever touched the feature you spent a fortnight on... that's the stuff that makes you a better maintainer. Wanting it is completely legitimate. The trouble is that the usual way of getting it, on by default and quietly hoovering up everything, is a small betrayal of the people who installed your tool to get a job done.

GeminiTTS: Gemini 3.8 TTS Online for Single-Voice and Two-Speaker Dialogue

If you have ever needed a quick voiceover for a demo video, a podcast intro, or a language-learning clip, you know the usual options: record it yourself, hire a voice actor, or wrestle with a robotic-sounding TTS engine.

Choose Cron Healthchecks over App Metrics — Safer Missed Cohort Rollbacks

A tenant-cohort experiment is only reversible while the team can tell, quickly and unambiguously, that a scheduled task stopped completing. Short answer: use a deadline heartbeat as the rollback trigger for missed runs, and keep application metrics as the diagnostic layer. Choose metrics alone only when the scheduler itself can reliably emit an absence signal and the alert query preserves tenant, cohort, region, and experiment-revision boundaries. That split matters for an e-commerce SaaS rollout. A new recommendation model might look healthy at the HTTP layer while its nightly catalog-enrichm

Kyverno Policy as Code no Kubernetes

Kyverno (do grego "governar") é um motor de políticas nativo do Kubernetes, projeto da CNCF, que permite validar, alterar e gerar recursos do cluster usando apenas YAML, sem aprender uma linguagem nova. Em clusters compartilhados, qualquer pessoa com acesso ao kubectl apply pode criar um Pod privilegiado, uma imagem sem tag ou um Service exposto sem querer. Revisão manual não escala, e documentação de boas práticas não impede ninguém de errar. O Kyverno resolve isso aplicando regras no momento em que o recurso chega à API do Kubernetes, antes de ele ser persistido no etcd. O diferencial frente

Push notifications on iOS without Firebase: talking to APNs directly from Laravel

Most push tutorials for iOS start with "add the Firebase SDK to your app". It works, but it means shipping Google's SDK inside your iOS binary just to forward a message to Apple, and keeping a second service configured for every app. Your Laravel backend can talk to Apple Push Notification service (APNs) directly. All it takes is a .p8 key, a short-lived JWT and one HTTP/2 request. This post walks through the whole thing, including the two mistakes that cost the most time: the wrong token type and the wrong environment.
