Is there a possibility you could change the title of the post to something relevant to its content? HN unfortunately has a policy against providing useful titles to links when page authors haven't done so themselves, and the intersection of people who will want to read your post and people who are interested in late medieval personal protective equipment is probably pretty low.
sadly, i clicked on it specifically because I was curious what PPE was available in the time of alchemy. what i found was boring code instead. 100% click-bait-n-switch
Me too! I mean I might be interested in object transmutation in Rust some of the time but not right now. Likely there are even more people in the converse situation, but they aren't the ones commenting on this thread.
HN policy also suggests using a representative phrase when the main title is misleading[1]; in this case the subtitle (The Path Towards Safer Transmute) seems suitable. (This can be changed either by the OP or by someone who bothers to email the moderators.)
