Many order and payment systems still run on Spring Boot 2.7 with Java 8 or 11, because "if it works, don't touch it." Standing still has a price: security patches stop, new libraries drop support for...
A very common configuration change on Kubernetes: changing dbHost in the values of a batch of sites, for example when moving the database from an in-cluster MySQL StatefulSet to a dedicated MySQL VPS....
The fastest way to get a database for websites on a cluster is to run MySQL right inside it: a StatefulSet, data on Block Storage, websites connecting through internal DNS. But after running it for a...
The previous article ended on an uncomfortable number: out of 22 questions, 4 never got the right passage into the top 3. When the right passage is not in the prompt, the model makes things up or refu...
A Laravel website runs on several pods, and to let the pods share one directory, that directory is mounted from an NFS server. Everything works well until the site starts hanging in waves: the pods ar...
The CI/CD pipeline is green, but the website is still running old code. At another time, the site hangs completely while MySQL and Redis are perfectly healthy. These two symptoms look very different,...
A single line, targetCPUUtilizationPercentage: 90 in values.yaml, is enough to give a Laravel website an HPA (HorizontalPodAutoscaler) that adds pods when load grows. But once you enable HPA and run a...
A Spring Boot project starts out clean: the controller calls a service, and the service calls a repository. Two years later, an @Entity shows up in the JSON response, a service imports HttpServletRequ...

A language model answers fluently about your store's return policy, but the "14 days" it quotes appears in none of your documents. That is why RAG (Retrieval-Augmented Generation) has become the defau...
A MongoDB instance without authentication can have all its data wiped, and when you move a Laravel website that uses MongoDB onto Kubernetes you usually hit two more errors in a row. The first is The...
In a GitOps setup, the pipeline that creates a website on Kubernetes usually ends with one step: commit the new site's values file to the Helm repo, then git push. When several pipelines run at once,...
