These da Vinci style drawings were likely created using the SketchUp models from sometime ago, which you can download from the page below to play with:

For those of you using CMake, have a look at the module below:

https://github.com/xrootd/xrootd/blob/master/cmake/XRootDVer...

and also the genversion.sh script at the top of the repo.

I use these plus #cmakedefine and git tags to manage the project version without having to do it via commits.

At CERN, software stacks are created centrally and software distribution for experiments is done with CVMFS (https://cernvm.cern.ch/fs/), an HTTP-based read-only FUSE filesystem.

EESSI (https://eessi.io) has taken this model further by using CVMFS, Gentoo Prefix (https://prefix.gentoo.org), and EasyBuild to create full HPC environments for various architectures.

CVMFS also has a docker driver to allow only used parts of a container image to be fetched on demand, which is very good for cases in which only a small part of a fat image is used in a job. EESSI has some documentation about it here: https://www.eessi.io/docs/tutorial/containers/

If you come to CERN, you can also see the NeXT machine that was the first web server.
