E aí, gurizada! De uns tempos pra cá, tenho percebido uma mudança significativa na forma como a gente interage com a Inteligência Artificial. Não é mais só uma ferramenta que responde perguntas ou gera imagens; a parada tá ficando séria, com a IA assumindo um papel mais ativo, quase como um colega de trabalho. Foi pensando nisso que gravei um vídeo recentemente, e a repercussão me fez pensar: "Car

Introduction Building a mobile application that handles sensitive financial data — crypto transactions, KYC verification, gift cards — means security is not an afterthought. It is a core deliverable. During the development of a cross-platform fintech application, one of the non-negotiables on the security checklist was runtime application self-protection (RASP). After evaluating our options, we
React Native's New Architecture — JSI, Fabric, and TurboModules — has been "coming soon" for long enough that some teams wrote it off as vaporware. It shipped. It is now default in new React Native projects. And it meaningfully changes how the framework works at the performance-critical boundaries between JavaScript and native code. This post is not a getting-started guide. It is an honest account

It's a one-line item on the roadmap. "Send a push notification when X happens." Estimate is two days, three if the backend doesn't have FCM credentials yet. There's a library for it. The library is the visible part. The other 90% is platform lifecycle, registration state machines, race conditions with navigation, payload archaeology, and a half-dozen iOS and Android quirks. Nobody writes them down
I have been building web apps for 12 years. In that time I never wrote a single line of mobile code. Not Swift, not Kotlin, not even a basic React Native hello world. That changed last month because of my wife. She has been using Synapse, the AI companion I built for her, every day from her phone browser. If you are new here, Synapse is a personal AI that uses a temporal knowledge graph instead of
For years I thought my only options were dual booting or using a clunky virtual machine. Dual boot meant constant reboots, and VirtualBox ate my RAM. Then I discovered Windows Subsystem for Linux 2, and honestly it changed how I work. Now I run a complete Ubuntu desktop right next to my Windows applications. I can code in a native Linux environment, test web servers, and even fire up Linux-only GU
