PHP released 8.5.12, 8.4.27, 8.3.36, and 8.2.35 to fix two critical vulnerabilities allowing unauthenticated remote code execution. Amazon recorded an exploitation attempt four days before the patches shipped, and operators spent the day working out whether they ran PHP, where to get the package, and how to tell it had landed.

Gergely Orosz is frustrated at those that entered his explicitly “No AI” essay competition and used AI. He goes on to say: When I start to suspect some part is AI about someone I don’t know: how can I tell how much of it is? And how much time and effort do I want to invest to figure out? I fear most people do not realize this last part: that when it takes time and effort from others to figure out what % is AI, and…

You submit a Kubernetes Job and wait for its Pods to appear. A minute passes. Then another. The Job is still suspended, there are no application logs, and there may not even be a Pod to inspect. In a cluster managed by Kueue , this can be completely normal. Kueue may still be deciding whether the Job can use the requested resources. The useful question is not only “Why is the Pod pending?” It is first “Has Kueue…

We give developers powerful APIs to build incredible capabilities into their apps for Apple products, backed by a set of controls designed to protect users’ private data. Full Disk Access largely sidesteps these controls in order to allow backup apps to function properly on the Mac. Some developers are using Full Disk Access in ways that could put users at risk, exposing everything on their systems—including files…

When software meets hardware, engineering principles remain largely the same, but the sensible defaults often change. Kuldeep Singh describes our experience modernizing a large IoT fleet of battery-powered sensors. Our familiar principles remained important; what changed was how we applied them. These practices emerged through experiments, failures, and operational experience—each challenge helping us replace a…
