Sentie. The Automated AI Consultant

Most "AI agent" products are chatbots with a fancy wrapper. They answer questions. They summarize documents. They draft emails you'll rewrite anyway. We built Sentie because we got tired of that gap — the distance between what AI demos promise and what actually runs in production. Here's what we learned building a platform that deploys autonomous AI agents for real businesses. The Problem Nobod...

Stop the Spin: Mastering Long-Running AI Tasks with Swift 6 Actors

We’ve all been there: you trigger a powerful AI feature in an app—maybe an image enhancement or a text summary—and suddenly, the interface freezes. The buttons don't click, the scroll stops, and the dreaded "spinning wheel" appears. In the world of modern iOS development, a frozen UI is the fastest way to lose a user. As AI models like LLMs and complex vision transformers become standard on-devic...

Tell HN: Claude 4.7 is ignoring stop hooks

I've been using Anthropic's hook features [0] since they were introduced. It allows me to inject determinism into my workflows. This worked perfectly until 4.7. Now, Claude routinely ignores the hook rules. For example, I have a stop hook that prevents Claude from stopping if a source file has been changed and no tests have been run.Here's the relvant part of the script: # Source edits made witho...

Claude Mythos: The 27-Year Bug That Should Terrify You

April 7, 2026. A date that should be etched into the memory of every security professional. Anthropic's internal logs flagged a zero-day in OpenBSD – the OS we've called unbreakable for decades. Your million-dollar security tools never found it. Theirs wasn't even looking for it. This wasn't some legacy garbage. OpenBSD is a fortress, hardened by decades of adversarial auditing. Every maj...

MongoDB is Great. Mongoose Makes it Better.

MongoDB is Great. Mongoose Makes it Better.

When I first started learning backend development, the database question came up almost immediately. Everyone has an opinion. SQL people will tell you it is the only correct way to store data. NoSQL people will tell you SQL is legacy thinking. I got confused fast, and honestly I am glad to have started with MongoDB. MongoDB is not always the right choice, but for a JavaScript developer learning b...

Attack Techniques: RMM Abuse

After you sign up on the Social Security Administration’s website, they’ll send you a yearly email inviting you to check out your benefits. Flipping through my Junk Mail folder this afternoon, I found the following email: It looks reasonably plausible, except for the return address (cuonlineedu.in, a university in India).

The Industry Quietly Killed Junior Developer Jobs

The Path That Used to Exist A few years ago, the path into tech felt almost predictable. You learned how to code, landed a junior position, and slowly grew into a senior developer. It wasn’t easy, but it was clear. That path still exists on paper. In practice, it’s quietly breaking down. What Changed Inside Teams I lead a development team in a high-pressure environment, and...

Google's Most Important NEXT '26 Announcement Wasn't a Model — It Was an Architecture

This is a submission for the Google Cloud NEXT Writing Challenge My Take Everyone left Cloud NEXT '26 talking about TPU 8t, Gemini 3.1 Pro, or the Apple-Siri partnership. Those are headline-grabbers, sure. But the announcement that will quietly reshape how we architect software got maybe 10% of the attention it deserved: Google shipped a complete, production-grade stack for multi-a...

Playwright Just Shipped the Fix For Flaky Tests I Built 3 Years Ago

I shipped a self-healing test framework three years ago. Nobody called it agentic then. The word "agent" was what your antivirus company ran on your laptop. I called my three internal components Planner, Generator, and Healer. Not because I'd read a paper — because those were the three jobs the pipeline needed and I was out of clever names. Last October, Playwright v1.56 shipped native Test Agen...

Gatekeeping Your Software

My Dad always told me something - you may not be able to certainly prevent a thief from breaking into your house, but it's your duty to make sure they use up all resources (time, energy, money etc) while trying to. Gatekeeping your software isn’t about restriction - it’s about control, trust, and accountability. It refers to implementing core security mechanisms i.e authentication, authorization,...

Etherealize Models $250K Ethereum Price in New Thesis But Presale Tokens Steal the Spotlight

Etherealize Models $250K Ethereum Price in New Thesis But Presale Tokens Steal the Spotlight

Ethereum climbed to $2,323 after a bold $250K valuation thesis tied to capturing gold and Bitcoin’s market share, with analysts projecting $5.5K–$7.5K this cycle. While ETH offers steady upside, Pepeto’s presale at $0.0000001866—with a live exchange, audit, and confirmed Binance listing—targets 10x–100x returns, positioning it as a high-risk, high-reward alternative during the current market phase...

Implementing a JSON Schema Validator from Scratch - Week 9

This was a pretty interesting week, it was more about what I didn't do rather than what I did do. What I Did I started this week with the goal of implementing the reference keywords, more specifically $id and $anchor. Unlike most of the keywords I've worked on lately, this required some serious foundational changes. Schema Registration In order to reference schemas, the sch...

AP2 Mandates Are Live on UCPReady — Here's What That Actually Means for Autonomous Payment

Zero merchants in Ben Fisher's 4,024-merchant UCP dataset support native payment. I've been building toward closing that gap since March. Today it's done — at least on the business side. This post is about AP2 Mandates: what they are, why they're the only spec-compliant path to autonomous card payment on UCP, and what it took to implement them correctly on WooCommerce. Why every UCP ...

Build for AI cold caller for outbound. Owners cant tell its a bot

I spent 3-4 weeks building an AI voice agent that cold-calls HVAC owners for me. Real outbound. Real objection handling. Real appointments booked. When we listen back through the recordings, the owners never clock it as AI — they just think its a human SDR with a slightly weird cadence. This is the build, and the honest reason its sitting on the shelf for high-volume right now. The stac...

Building a Fault-Tolerant Node.js Backend: 4 Patterns I Applied to My Ticketing App

Starting to Build a One‑Person Company on Azure with OpenClaw (No Code, Just Chat)

What I Built I built a fully automated daily campaign‑letter summarizer running on an Azure VM using OpenClaw. Every morning at 9am, my AI agent scans a folder of campaign letters, summarizes them, and writes a clean daily report. The most interesting part? I didn't write any .claw files, YAML, or Python glue code manually. Instead, I discovered that OpenClaw can create skills and cro...
