When an AI agent can run shell commands in your pipeline, its permissions are infrastructure. They should be declared where reviewers look, versioned with the agent, and tested on every change. Docker Agent gets the first two right. The third is up to you, and when I wrote the tests, one widely used permission pattern … Read more

In September 2024, War Robots support received a surge of complaints from Chinese iOS players: after updating to iOS 18, in-game text was displaying incorrectly for some users. The issue manifested differently across devices: some players noticed missing characters, while others reported wrong or unfamiliar glyph styles. To make matters worse, we were unable to … Read more

Four months after Operation Endgame took it down, StealC’s seller returns with Stadia, a remote access trojan that shares StealC’s code byte for byte. In June, Europol tore down StealC, a prominent infostealer, as part of Operation Endgame. International authorities seized 326 servers and 142 domains, recovered more than 25 million stolen credentials from 385,000 … Read more

On 3rd October, my astro-coach agent tried to fix a production Supabase environment problem. It kept retrying until a model usage limit stopped it. The tempting summary is “the agent tried to fix production.” That summary hides most of the engineering. Step in the 3 October astro-coach run Who did it What it handed on … Read more

Most articles about database migrations assume you know the final model before you start. In real products, you often don’t. You ship a design, it goes to production, and then a customer conversation tells you the design was wrong. In 2026, I designed and built a speaker roles feature for an event platform, end to … Read more

Editorial Note: The article contained quite transparent AI disclosure at the end, which we decided to keep, as it supports the argument made by the author. These days, you hear it everywhere—especially when someone reviews your proposal, evaluates your draft, or critiques your article: “Ohhh! It was made by AI! I knew it! I could … Read more

Understanding Dynamic Task Executions in Apache Airflow Apache Airflow is a powerful platform for orchestrating complex workflows, but as workflows grow more dynamic — featuring loops, retries, and mapped tasks — tracking the state of each task execution becomes increasingly challenging.

A room sketch can answer a small programming question: do two furniture footprints overlap, and does each footprint stay inside the room? Represent the room and each piece as rectangles, then run those checks whenever a coordinate changes. This gives you a repeatable way to compare a few layouts before ordering. Keep the sketch beside … Read more

Hackathons give developers a reason to experiment with new technologies and build working projects, while offering companies an opportunity to put their products in front of developers through hands-on experience rather than traditional advertising. However, the value of a hackathon doesn’t have to end when submissions close and winners are announced. With the right partnership, … Read more

Product teams are usually good at defining what they want to improve: paid conversion, engagement, churn, search success, or transaction completion. The harder question is not what to optimize. It is: what behavior must change elsewhere in the system for this metric to improve? Product metrics do not move on their own. They move because … Read more

Citrini Research has no lab, no biologists, and no drug discovery experience. It flew to Anthropic’s New York office, ran an unreleased Claude against five scorpion toxins, and paid the wet lab on a credit card. The number everyone is quoting from Anthropic’s scorpion antivenom post is 318,484 — the count of protein designs an … Read more

ANY.RUN researchers tracked fake AI tool campaigns that impersonate Claude, ChatGPT, GitHub Copilot, Gemini, and other AI brands to plant infostealers, take over browser sessions, and phish business accounts. Between April 15 and October 5, 2026, 1,258 public sandbox analyses were tied to these campaigns, and the USA was the second-largest source of submissions after … Read more

Hero image: Original AI-assisted illustration created for this article. A marketing team asks an assistant to write a service page. The assistant finds three internal documents with different prices, an old presentation with a retired credential, and an impressive customer result whose publication permission nobody can locate.

TL;DR Three services in two languages means three seams, and a hand-maintained seam is a slow leak. Declare the shapes once on the server, generate everything else: OpenAPI becomes a typed REST client, AsyncAPI becomes a typed WebSocket client in TypeScript and another in Python. The compiler then tells you what broke instead of a … Read more

At Amplitude, I’ve connected Claude to Salesforce four different ways. Each version fixed something the last one got wrong, and what I learned in the end had little to do with hosting or transport. It was about what the model should be allowed to see. Where this started The sales rep says, “How’s the Acme … Read more

Image source: Pixabay.com/Placidplace TL;DR Unlike traditional SaaS, AI agents deliver uncertain value at a cost that keeps shifting, and that combination breaks the pricing logic SaaS was built on.

__Basware __CEO Jason Kurtz points to an automotive manufacturer that spent 18 months building a custom AI system for expense reporting. He estimates a specialist product could have solved the same problem in about 12 weeks, at one-tenth the cost. Companies should be getting less patient with projects like that one. Capable models are now … Read more

Picture this. Your AI agent is doing research for you, reading web pages, calling APIs, and summarising what it finds for the rest of your system.
