🏢 Building Enterprise-Ready AI Agents 🤖 — A Practical Field Guide 📚

How to design, ship, and operate an AI agent that is reliable, efficient, performant, scalable, and secure enough to serve real companies — from a 5-person startup to a 50,000-person enterprise. This guide distills hard-won lessons from production agents (Claude Code, OpenHands, SWE-agent, GoClaw, Hermes, nanobot, PicoClaw, ZeroClaw, Multica, Paperclip) and grounds them in current engineering gu...

The Model Is the Easy Part: What a Real-Time Computer Vision Product Actually Takes

I used to think computer vision was a model problem. It is a pipeline problem, and the model is the easy part. Here is the pattern I keep seeing. A team trains or fine-tunes a detector, it hits some impressive number on a curated clip, everyone claps, and then it goes into the real world and falls over. The lighting is wrong. The camera moved. Someone wore a color the training set never saw. The ...

TELESHIM Abuses Telegram for C2 in Attacks Against Middle East Governments

TELESHIM Abuses Telegram for C2 in Attacks Against Middle East Governments

Cybersecurity researchers have flagged fresh malicious cyber activity by a threat actor with ties to East Asia targeting government entities in the Middle East. The intrusions have resulted in the deployment of previously unreported malware families dubbed TELESHIM, MIXEDKEY, and BINDCLOAK, according to Zscaler ThreatLabz. The cybersecurity firm said it detected the campaign earlier this month.

How to Build Rock-Solid Real-Time Data Pipelines from the Factory Floor IoT

Lessons from hooking up stamping presses, welding cells, and MES without dropping a single byte of data. If you’ve ever been tasked with trying to feed live sensor data from industrial gear into a modern app architecture, you’ve no doubt learned quickly that the shop floor is not exactly a cloud-native paradise. Automotive component manufacturing, in particular, is where we often get our toughest...

Removing Video Watermarks Entirely in the Browser with MI-GAN, ONNX Runtime Web, and WebGPU

Watermark and unwanted-object removal is one of those features that looks simple in a model demo and becomes much more complicated when you put it inside a real video editor. The obvious implementation is to upload the media to a GPU server, run an inpainting model, and return the result. That works, but it introduces upload latency, infrastructure cost, and privacy concerns—especially for large ...

From Java Monoliths to LangGraph Agents: What Transfers

I spent ten years building enterprise Java systems — a payments monolith broken into Spring Cloud microservices, banking applications, and currently a Cisco security platform. More recently I moved into building LLM systems seriously. The surprise wasn't how much I had to learn. It was how much transferred. Agentic systems are distributed systems. The vocabulary is new; the failure modes are not....

I Was Filming a Demo of My Monitoring Tool. The Monitor Wasn't Monitoring.

This is a submission for DEV's Summer Bug Smash: Smash Stories powered by Sentry. The project workers-monitor is a Cloudflare Worker I run to watch a small fleet of my own Workers. Hourly cron, deterministic threshold gate, Claude Haiku judgement only if the gate trips, Telegram alert if Haiku confirms something's actually wrong. A quiet hour makes zero LLM calls. github.com/dannwaner...

Permission-Aware RAG: Enforcing Document ACLs at Retrieval Time

Most RAG demos have a security model of "none." Documents go into one shared index; anyone who can ask a question can surface content from any document. In a compliance or financial domain, that's not a rough edge — it's a disqualifier. When I built Atlas, an enterprise copilot for a compliance domain, the first architectural decision was where access control lives. There are three options, and t...

The Cloudflare Worker That Ran Perfectly and Still Failed Twice

This is a submission for DEV's Summer Bug Smash: Clear the Lineup powered by Sentry. Project Overview workers-monitor is a Cloudflare Worker that watches a small fleet of my own Workers. Hourly cron, pulls fleet metrics from Cloudflare's GraphQL Analytics API, runs a deterministic threshold gate, and only calls Claude Haiku to judge signal-vs-noise if the gate trips. If Haiku confirms ...

Your BigQuery bill is a query-shape problem. We cut one 72% in three weeks.

BigQuery doesn't charge you for having data. It charges you for touching it. On-demand pricing bills per byte scanned, which means your bill isn't a data-size problem or a traffic problem. It's a query-shape problem, and query shape is fixable in an afternoon per table. A recent client was a textbook case. Dashboards running SELECT * over an unpartitioned events table, so every refresh scanned th...

Your Claude Code skill's description is being cut: the 1,536-char cap and the shared listing budget

You wrote a skill. The description is clear. You ask for exactly the thing it does, and Claude reaches for something else. Before you rewrite the description a fourth time, check whether Claude ever saw the whole thing. Two separate limits trim skill metadata before the model reads it, and both are silent. The two limits are not the same limit Claude Code loads a listing of your skill...

Why Your Playwright Tests Are Lying to You (And How to Actually Fix Flakiness)

Why Your Playwright Tests Are Lying to You (And How to Actually Fix Flakiness)

Flaky tests aren't random — they're deterministic bugs you haven't found the trigger for yet. This post covers the 8 real root causes, how to reproduce flakiness on demand instead of guessing, and the fixes that actually stick. Code examples throughout. You've been there. A test fails in CI. You re-run it. It passes. You shrug, blame "the network," and move on — until it fails again three da...
