Five Eyes to Developers: AI-Powered Cyberattacks Are "Months Away, Not Years"

On June 23, 2026, the cybersecurity chiefs of all five Five Eyes nations — the United States, United Kingdom, Canada, Australia, and New Zealand — did something they almost never do together: they put their names on the same statement and told governments and businesses to act now. The message was blunt. Frontier AI models are about to reshape both offensive and defensive cyber operations, and the runway is short: "the timeline is not years, it is months." The three-page statement was published

Running, Voice, and Inspiration: A Thought Precipitation System

I've always felt that you need to set aside time to think. No matter how smart AI gets, someone still has to tell it what's worth thinking about. The truly good ideas still have to come from your own mind. But when you're sitting at your computer, information keeps flooding in. It's rare to have truly quiet time. I've been looking for a way to let those scattered thoughts rise to the surface on their own. Turns out, running does exactly that. It's not that running has some magical power. It's ju

Partner Pipeline Playbook for AIKit: Turning SEO Articles into Affiliate Revenue

Short answer: AIKit can turn blog traffic into a sales channel by giving every high-intent article a partner-ready path: clear offer, tracked referral link, qualification rules, and a simple follow-up sequence. The goal is not to add random affiliate banners; it is to build a measurable pipeline where SEO readers become partner introductions, demo calls, and revenue. Most content programs stop at publishing. A team writes a helpful article, waits for search traffic, and then measures success wit

The Nex Playground is down to its pre-RAMageddon price during Prime Day

You gotta admit, it looks like fun. | Photo: Sean Hollister / The Verge The Nex Playground is the family-centric, Kinect-like game console that made one Verge editor’s kids laugh, cry, and ask for more playtime, even when they were sick. The motion-based game play isn’t perfect, but it has won over plenty of parents — and it’s on sale for $239 at Amazon, down from its current MSRP of $299. That’s a healthy discount, though only slightly better than the Nex’s original $250 price. Nex Playground

Running a LangGraph ReAct Agent in Production: OpenAI-Compatible API + Multi-Model Gateway + One-Line Tracing

Most LangGraph content stops at the notebook. You build a cute ReAct loop, it answers one question, and the article ends before the hard part: how do you actually serve this thing, swap models without a rewrite, and see what it's doing when it misbehaves? This post walks through a small but production-shaped LangGraph deployment: a RAG ReAct agent that exposes an OpenAI-compatible HTTP API, so any OpenAI client (Open WebUI, the openai SDK, LibreChat) can talk to it unchanged, routes every model

The SaaS Churn Rate Formula: 3 Calculations That Expose Your Real Runway Risk

This article was originally published at https://saastools.corenk.com/articles/saas-churn-rate-formula You closed the month at $12,750 MRR. But when you opened your dashboard on the 3rd, $890 had quietly walked out the door — six cancellations, one downgrade, and two payment failures that won’t retry. That $890 won’t come back. And next month, the same silent arithmetic starts all over again. If the only number you’re tracking is a rough churn percentage from your billing tool, you are flying in

I built an open-source crypto trading bot that runs 4 exchanges from one server

GainAlgo is an MIT-licensed crypto trading bot I've been building. The latest update lets it manage four exchanges from a single server and one dashboard: Exchange Futures (USDT-M) Spot Binance ✅ ✅ Bybit ✅ ✅ Upbit — ✅ Bithumb — ✅ That's 2 futures + 4 spot markets, all in one process. On its own, the bot is roughly break-even. I think of it as tilling the field and standing guard 24/7 — the human still does the final harvest. Defaults are deliberately safe: every engine off, paper
