Reach your home Mac from anywhere with Tailscale (so Claude Code can come with you)

If you've started running Claude Code or any other AI coding agent on a Mac at home, you've probably already had this thought: "I should be able to talk to that machine from my phone." Then you tried to actually do it, and you ran into router config, dynamic DNS, port forwarding, and somewhere around the third firewall rule you closed the tab and went back to coding at your desk like a normal pers...

From Hello World to Production: My Brutal Journey with BRAG AI Agent Development

From Hello World to Production: My Brutal Journey with BRAG AI Agent Development Honestly, when I first started building BRAG, I thought I'd be one of those people who creates an AI agent in a weekend and writes a triumphant blog post about it. Spoiler alert: that's not how this story goes. Six months later, after destroying 17 different versions and questioning my entire career path,...

WhatsApp Bot for Business 2026 — $1K-$4K (50+ Real Builds)

WhatsApp has over 2 billion users worldwide. If your customers are on WhatsApp (and they probably are), a bot can handle inquiries 24/7, book appointments, and qualify leads — while you sleep. But there's a catch: do it wrong, and Meta will restrict or ban your number. I've seen businesses lose their primary WhatsApp number because they used the wrong tool, sent messages to people who didn't opt ...

Cursor Rules for TypeScript: 6 Rules That Make AI Write Type-Safe TypeScript

Cursor Rules for TypeScript: 6 Rules That Make AI Write Type-Safe TypeScript Cursor generates TypeScript fast. The problem? It reaches for any the moment things get complex, returns bare objects instead of typed responses, skips discriminated unions, and writes error handling that throws away type information. The fix isn't better prompting. It's better rules. Here are 6 cursor rules ...

User-Generated Content Isn't Free, It's Just Debt in Disguise 🎭

We bought into the UGC hype like everyone else authentic content from real users, zero production costs. It sounds like the ultimate marketing hack until your campaign actually goes viral. Then, the brutal truth hits: UGC doesn't eliminate costs; it just shifts them into moderation hell. Instead of paying creators, you’re paying reviewers. Instead of production timelines, you’re building massive...

Calculer un TAEG en JavaScript avec Newton-Raphson : la méthode propre

Le TAEG (Taux Annuel Effectif Global) d'un prêt immobilier n'admet pas de formule fermée. Il faut l'approcher par itérations successives à partir de la mensualité, du capital et de la durée. La méthode de Newton-Raphson converge en 4 à 8 itérations sur les profils classiques — bien plus rapide que la dichotomie utilisée dans la plupart des simulateurs JavaScript que j'ai audités en 2026. ...

Migrating from Google Analytics to Privacy-Focused Alternatives

So you've finally decided to ditch Google Analytics. Maybe it's the GDPR headaches, maybe it's the bloated JavaScript bundle, or maybe you just don't want to hand your users' data to the world's largest ad company. Whatever the reason, welcome to the club. I migrated three projects off GA4 over the past year, and each time I picked a different privacy-focused alternative. Here's what I learned co...

Field Notes from a Solo Builder — Shipping the Beloved Claude Code Buddy Into the Wild - Part II

The alpha was out. But I wasn't satisfied with the architecture. The original Buddy had a fundamental fragility: tightly coupled to Claude Code. Every version upgrade could wipe it. And if you weren't running Claude Code specifically, you were excluded entirely. I didn't want to rebuild the same fragility. The First Principle: No CLI Dependency The core architectural decision was s...

🚀 vem is in early access — we're looking for our first users. If you try it and find it useful, we'd love to hear from you. Early access is completely free. Your AI coding agent is smart, but it has no idea what you're working on this week. Every new session starts from scratch — no sprint goal, no priorities, no sense of what's blocked or nearly done.

From Knowledge Base to AI System: How Papers Evolved Beyond My Wildest Dreams

From Knowledge Base to AI System: How Papers Evolved Beyond My Wildest Dreams I'll be honest - when I first started Papers two years ago, I had no idea what I was getting myself into. I just wanted a place to store my technical notes, maybe organize them a bit better. What I ended up with was something that feels like having a second brain, but with all the messy, unpredictable personal...

ANÁLISE ACERCA DO FRAMEWORK GRPC (GOOGLE REMOTE PROCEDURE CALL): COMPARAÇÕES E DESEMPENHOS

RESUMO A adoção crescente de arquiteturas de microsserviços trouxe à tona limitações concretas do modelo REST sobre HTTP/1.1, protocolo que dominou a integração de aplicações web por décadas. Serialização em JSON, ausência de multiplexação nativa e cabeçalhos verbosos representam gargalos reais em sistemas de alto volume. O gRPC, framework open source desenvolvido pelo Google, propõe um...

The Failure Mechanism in OT Systems: Identity Boundaries at Execution Context

Opening Position Operational technology security does not fail because operators lack awareness. It fails because the control layer enforces no identity boundary at runtime. IT/OT convergence has been treated as a networking problem - segment the traffic, firewall the boundary, monitor the flows. This assumes the protocols behind the boundary enforce their own trust. They do not. OPC U...
