Property-based testing: How to find bugs your unit tests miss

Property-based testing is a software testing technique that checks whether a program satisfies general rules, called properties, across many automatically generated inputs. Instead of writing tests for individual examples, developers define how their code should behave and let a testing framework search for inputs that break those rules.

Introducing CircleCI Functions: Reusable CI steps built for coding agents

CircleCI Functions are now available in beta, giving developers and coding agents a faster, more reliable way to set up CI pipelines using reusable, tested steps. Functions are the next evolution of CircleCI orbs. They make common CI tasks, like installing programming languages, configuring AWS credentials, and setting up Docker, available as ready-to-use programs that agents can discover, configure, and validate before running a pipeline.

The Evaluation Factory: How We Make Agents Measurably Better, Run After Run

Ask a team running an agent in production whether last week’s change made it better. Most can’t say. They swapped a model or rewrote a skill, eyeballed a few runs, and moved on. That works for a demo. It doesn’t work for an agent that touches production, where customers want two things that pull against each other: precision where a mistake is expensive, and low cost where the work is routine. A root cause someone acts on has to be right.

What Is the Harness Software Delivery Agent? | AI-Powered CI/CD Explained

What is the Harness Software Delivery Agent? Harness Software Delivery Agent is an AI-powered software delivery solution that helps teams automate CI/CD pipelines, infrastructure workflows, deployments, and troubleshooting, moving code from commit to production while enforcing existing policies and approvals. In this video, we explain how Harness Software Delivery Agent works and how it helps DevOps teams, platform engineers, and developers automate software delivery.

It was the best of times, it was the worst of times, for software security

Microsoft fixed more than 1,400 vulnerabilities in its October Patch Tuesday. That’s one month, and it’s more than in all of 2025. Two weeks later, Anthropic said an unreleased Claude model had found and exploited serious vulnerabilities in Chrome, Safari, Android, Windows, and Linux. AI is finding bugs faster than anyone can fix them. Inside CertKit, we’ve been quoting Dickens, “It the worst of times.” AI makes our small team fast.

The voice of the customer at the heart of progress: why NPS matters to Almaden?

The customer satisfaction survey is more than a metric. It is the tool that connects users’ real-world experiences to the decisions shaping the future of Collective IQ. At Almaden, we believe that a product is not built solely on technical requirements or market trends. Above all, it is built by listening to the people who use it every day. That is why Net Promoter Score (NPS) plays a central role in our strategy. It is not just a number.

Never lose robot data again: automatic ROS 2 bag recording and upload

If you work with robots, perhaps you’ve come up against a common, but annoying situation: the one field run that mattered is the one nobody recorded. Or it was recorded but the ROS 2 bag (a recording of ROS 2 topics) is sitting in the robot’s storage, at a customer site, three time zones away. This issue is commonly caused by manually starting ros2 bag record and using scp to copy gigabytes off the robot after every test, which just does not scale.
