Once projects grow larger, AI tools start behaving...

Agent payments are the new cloud bill footgun

AWS has been previewing more AgentCore pieces, and one small phrase should make platform teams sit up a little straighter: managed payment capabilities for agents. Not just agents calling tools. Not just agents reading docs. Agents paying for APIs, MCP servers, web content, and other agents as pa...

Pressure-testing Ota on Supabase: from setup prose to executable repo readiness

Supabase already has strong contributor documentation. That is not faint praise. The docs are good. But good docs and executable readiness are not the same thing. Before Ota, the www/docs contributor path still depended on a familiar manual loop: read the docs infer which workflow is the intende...

The Future of Text Analysis: Introducing TechnoHelps Semantic Engine

The Cost of Black-Box Analytics As a developer, I have always been fascinated by how we process data. When I started building my own content platforms, I hit a wall that many of you probably recognize: the "Black Box" problem of analytics.

95+ browser-based dev tools that never touch a server

Every developer has a folder of bookmarks for one-off tools — a JWT decoder here, a Base64 encoder there, a cron expression tester somewhere else. Half of them send your data to a server you know nothing about. I built Wizbit.to to fix that. What it is 95+ free developer utilities, a...
