I despised how data sets and code were considered a gold-mine and researchers would often refuse to release them lest they give up a serious paper publishing advantage for their group. More often than not, i found code full of serious errors and completely lacking basic test cases and sanity. Sometimes the data sets were much larger than the subset chosen for publication.
