Yes, these are all official scientific volcanological terms. Yes, volcanology is a very much male dominated field 🇮🇸 #iceland #vulcano #volcanology #science #lava #lavacave This beach reminds me so much of Bunes Beach in Lofoten ❄️🇮🇸 #snæfellsnes #snæfellsnesjökull #iceland  #beach #blacksand

Clean up dangling images from Docker

I almost exclusively run FEniCS using Docker and have recently noticed that building images from Dockerfiles often results in a lot of <none>:<none> images showing up when I run docker images. This is different from images labelled the same showing up when running docker images -a (in that case they are “intermediate” images since Docker images are composed of layers).

The <none>:<none> images that show up when running docker images are references to old images after for example updating an image since updating an image does not actually update it, but creates a new image for the new version and leaves the old one dangling as a <none>:<none>. Docker does not have its own garbage collection, so this has to be done manually using the following terminal command.
