The battle between the two leading AI developers seems to never stop. The newest chapter: OpenAI has released a major update to its Codex platform, repositioning the tool from a coding assistant into an automation layer operating across a developer’s environment. The release is clearly an effort to keep pace with Anthropic, whose multi-faceted Claude Code is gaining big traction in the lucrative enterprise sector. The most important improvement is Codex’s ability to act directly within a user’s operating system. The platform can now interact with applications by issuing commands that simulate user behavior, including opening programs and typing inputs. On macOS systems, multiple…

The XZ Utils backdoor was a wake-up call, but the underlying problem it exposed has not gone away. Sophisticated adversaries are playing the long game, spending months or years earning trust within open source projects before introducing malicious code into libraries that sit at the foundation of modern software infrastructure. Mike Vizard and Josh Bressers, VP of security at Anchore, dig into why the software supply chain remains dangerously vulnerable and what the industry is getting wrong in its response. Bressers points out that the vast majority of open source projects are maintained by a single person or a very…
Thanks to everyone who joined the blog party this month. I noticed three themes in the responses. Every response had one or more of these themes woven into their response.I learned something.I discovered ways to improve my presentations.I get more value in the hallway conversations.No matter how you learn, you can find value at conferences. Our industry is made up of people with different learning styles. I learn best in a classroom. Others prefer hands on experience. Before we recap the responses, let’s have a look at the invitation.The InvitationWe are in the heart of the spring conference season. Maybe…

Leapwork this week revealed it is infusing agentic artificial intelligence (AI) capabilities into its test automation platforms to enable continuous validation across application testing workflows. Company CTO Rohit Raghuvansi said that as the pace of application development accelerates in the age of AI, it’s become apparent that test validation has become an even bigger software engineering bottleneck. In fact, a recent Leapwork survey finds that as adoption of AI coding tools increases, the amount of budget dollars allocated to quality assurance and validation is rising to consume 35% to 40% of application development budgets. Leapwork is addressing this issue with…

Most developers know the drill. You write a script. You set up a cron job. You wire it into some monitoring tool and pray it runs cleanly overnight. Then something breaks, your laptop was asleep, and the task never ran. Anthropic is trying to fix that with Claude Code Routines, now available in research preview for Pro, Max, Team, and Enterprise plan subscribers. What are Routines? A routine is a saved Claude Code configuration — a prompt, one or more repositories, and a set of connectors — packaged once and run automatically. Think of it as putting your most repetitive…
