Production agents need two persistence layers: thread-scoped state and cross-session memory. Google ADK Sessions stores events and state for a single conversation, while MemoryService handles recall across sessions.

The Entrepreneurial Conundrum

I have business ideas all the time. Every few days something pops into my head, usually triggered by some frustration or gap I notice in daily life. Sometimes I jot them down. I'll even flesh a few out, turn a vague thought into something that feels almost real. Then I lose interest. Or I realise I...

How to Extract OTP Codes with AI Agents — One API Call

How to Extract OTP Codes with AI Agents — One API Call Every AI agent hits the same wall: email verification. 80% of online services require an OTP to sign up. Your agent can fill forms, click buttons, solve captchas — but it can't check an inbox. I built SandMail to fix this. One API call creates...

An AI-Ready NestJS + Next.js Boilerplate for 2026

RAG From First Principles: Why Every AI App Retrieves Before It Generates

Large language models have a problem nobody talks about at the beginning. You train a model on terabytes of internet data. It knows a lot. But it doesn't know your data — your company's policies, your product docs, last week's incident report, or the contract you signed yesterday. Ask it anyway, a...

Don't Use AI to Do This

AI is useful. I use it too. But there is one thing I really do not think you should hand over to it too early. Do not use AI to replace your first round of thinking. That first messy pass matters more than people admit. It is where you figure out what you actually believe, what you do not understa...

We covered worktrees in our 10 Claude Code tips you didn't know: tip 6 covers the --worktree flag and how it works...

The surprise AI bill that made me build TokenBar

I kept opening my AI tools and losing track of what I was spending. Not because I was doing anything shady. Just because token usage is invisible by default. You send a few prompts, the model retries a few times, you leave a tab open, and the bill shows up later like a prank. That was the problem...
