The PHP security incident is now (almost) old news. The timeline looks something like this: In late August, Wiz Research discovered two serious remote code execution vulnerabilities in PHP called PHP2Shell. They reported the vulnerabilities to the PHP team on August 24, which started working on fixes on September 21. Amazon apparently detected PHP2Shell in […]

The following article was originally published on James Shore’s Successful Software blog and is being republished here with the author’s permission. Software development has emerged as the biggest beneficiary of AI automation. One CIO I talked to recently, with 170 people in his organization, measured a 2.1x increase in productivity from AI. That productivity came […]

The following article originally appeared on The Arize Blog and is being republished here with the author’s permission. Every time you think you’ve just got the hang of this AI thing, another thing gets declared “dead.” This week, it’s agent harnesses. Back in ancient history, aka June, I wrote a piece called “Frameworks are dying, […]

AI’s rapid expansion is creating problems across the industry, from chip shortages to autonomous agents that exceed their instructions. On the latest episode of This Week in AI, we examined those challenges alongside growing regulatory scrutiny and an emerging debate about whether AI systems themselves might deserve protection. Chip production can’t match AI demand AI […]

Spend a week with almost any infrastructure team in 2026 and you’ll see one AI subscription producing five very different results. One engineer opens 40 pull requests before lunch across repositories they haven’t touched in a year. Another ships a Terraform change they couldn’t explain in a code review. A third hasn’t opened the tool […]

Created by Claude with light editing by Tim O’Reilly Raffi Krikorian, Mozilla’s CTO, joined Tim O’Reilly at our recent AI Codecon to talk about open source AI. Mozilla, of course, is the nonprofit that helped to define the open source revolution back in the late 1990s. Though its Firefox web browser was superseded as the […]

The following article originally appeared on the Vanishing Gradients Substack and is being republished here with the authors’ permission. Stripe’s Minions turn engineering requests into candidate pull requests. Ramp’s Inspect puts coding agents to work in the background, with tools to check their changes. Warp Factories takes work from tickets and chat through agents, checks, […]

If you’re an instructor for the O’Reilly live training platform, you’ve got to be prepared for the unexpected. As a developer I think we all can understand the situation when a demo (you know, the one that you’ve tested a thousand times on your machine) easily decides on its own to go wrong while being […]

In my work with G7–G12 students at Force Academy, a research initiative in Chongqing, I sometimes take a project that appears to be finished and give another student responsibility for using, checking, or modifying it. The handoff is a test of understanding: Can the work still make sense when its creator is no longer there […]

One of my biggest pet peeves is the Monday morning quarterback, the person who second-guesses every coaching decision after the fact. In The Monday Morning Agent, we’re building one that actually checks the data. Every other Monday, I’ll take an argument NFL fans can’t stop having and hand it to an AI agent. We’ll use […]

This summer, I built a small experiment called ContextCue. The idea came from something I kept seeing during my internship. The engineers around me were using AI everywhere in the software development process. GitHub Copilot and Claude models helped with specs, code, reviews, and tests. The team also maintained reusable skills that taught coding agents […]

New AI tools are making business data easier to explore. They’re also giving researchers new ways to study disease outbreaks and physical systems. On the latest episode of This Week in AI, we examined developments from OpenAI, Anthropic, and Mistral, new research on the economics of robotics, and how scientists are using AI to tackle […]

In my previous article, I argued that agentic development needs enough specification to make correctness checkable. A quick prompt can get implementation started quickly, but someone still has to decide whether the result does what we wanted. I left a fairly practical question unanswered, though. Once the agent has written the code, how should we […]

The following article originally appeared on Addy Osmani’s Elevate blog and is being republished here with the author’s permission. For much of human history, we’ve evaluated code quality via code review: Someone reads what you wrote and makes sure it’s clean, thoughtful, fast, understandable, and tests well. For agents, that approach doesn’t scale well; there’s […]

I use AI for writing all the time. But not because it’s good at writing. In fact, just the opposite is true. AI is so reliably bad at writing that I’ve actually taken advantage of that, and made its bad writing an integral part of my writing process. I’ve written a lot of books and […]

In my previous Radar article, “Architectural Guardrails for AI-Generated Code,” I argued that AI coding agents need a layer that can hold architectural decisions in a structured corpus, retrieve the relevant ones, put them into the agent’s context before it writes code, and enforce explicit constraints with reproducible checks. Testing that model exposed two distinctions […]

In the final episode of Zero to Agent in 30 Minutes, AI engineer Sajal Sharma showed how to build a personal assistant on OpenClaw that tracks your tasks and notes and handles scheduled work on its own. A useful personal assistant has to be reachable when you’re away from your computer and keep running when […]

The following article originally appeared on the Agentic AI Foundation blog and is being reposted here with the author’s permission. Websites are designed for people. We can look at a page and quickly understand where to enter information or which control will complete an action. AI agents don’t see or use the web the same […]

AI systems are gaining more autonomy while governments, companies, and researchers are still working out how much oversight they need. On the latest episode of This Week in AI, we covered the US debate over AI governance, new frontier models, persistent agents, world models, and practical uses for AI in healthcare and disaster response. AI […]

On a recent episode of This Week in AI, we discussed that the number of nonhumans on the internet is greater than humans, 144 to 1. It’s an estimate, and the order of magnitude is more important than the number itself. What matters is what a ratio anywhere in that range does to a security […]
