This section was made a long time ago, and is barely even maintained. Many of the generic data-related things are now on aalto.fi and the version on scicomp.aalto.fi should be removed.
I propose that the /data/ section centralize data-related things focused on scientific computing: for example requesting data storage space on the cluster/in our departments and some of the tools necessary for processing large amounts of data efficiently.
I'd start with a clean slate and only transfer in content which is known to be useful.
