Orthanc is an open-source PACS server written in C++ with an extensive interface for plugin development. Here we announce orthanc_sdk, a library for developing Orthanc plugins in safe and idiomatic Rust. This article explains why Rust is a good language for Orthanc plugin development and the design of the orthanc_sdk crate.

Sometimes, you come across an edge case in production that is just not feasible to reproduce in a development environment. Or, it's more convenient to forego best practices and debug against the real user data.

Debugging in production is a bad practice, furthermore a Kubernetes environment can make things even harder. But for whatever reason, sometimes you have to do what you have to do. Here are some tips on how to debug a Django application in production on Kubernetes.

At this year's scientificcomputing.rs workshop, Jennings gave a presentation about the DICOM protocol and how we developed ChRIS to support it.

Dr. Rudolph Pienaar and Dr. Ellen Grant presented at Red Hat Summit 2024.

ChRIS is now available on the NERC at https://app1.chrisproject.org. This deployment is a milestone comprising many improvements to ChRIS made in 2023.

To shrink a PersistentVolumeClaim (PVC) in OpenShift or Kubernetes, we need to:

1. pause our deployments
2. copy its data to a smaller, temporary PVC
3. delete the original PVC
4. create a new PVC with the original name
5. copy the data from the temporary PVC to the new PVC
6. restart our deployments

tl;dr the container filesystem lives in-memory, so temporary files and directories which don't get deleted will eat up RAM.

1. Containers are useful for portability
2. Containerization shifts the burden of software installation to the developer/publisher, not the users
3. Containers are useful for compatibility
4. How to use Docker CLI (properly)
5. Using Apptainer as an alternative to Docker
6. Running containers locally, on E2, and on ChRIS
