I've found that it's common for computer science papers to reveal only about 60% of what is necessary to reproduce the result. Crucial steps of the algorithm are omitted. Numerous constants are used with no value ever given. Preprocessing steps are alluded to but never discussed. Datasets are kept private, or worse, charged for. Anecdotally, I'd say that this seems to have been a worse problem in the 1980s and 90s, judging papers from that era. But it's still an issue today, especially with systems papers.
