His father was a complete piece of shit and treated him horribly and also he was never really allowed a proper childhood.

So I have heard some people argue that perhaps he was not a pedophile, but rather just really mentally ill, partly believing to be a kid that just wanted child playmates. Still wrong for an adult to act like this, but perhaps there was no sexual misconduct.

Not sure what to believe and perhaps I just don't want him to be a villain, but I would like to hear if there is some concrete evidence.

Let me take a stab at it:

Problem: Given two list of length n, find what elements the two list have in common. (we assume that there are not duplicates within a single list)

Naive solution: For each element in the first list, check if it appears in the second.

Bogo solution: For each permutation of the first list and for each permutation of the second list, check if the first item in each list is the same. If so, report in the output (and make sure to only report it once).

Well, I guess PDF has one thing going for it (which might not be relevant for scientific papers): The same file will render the same on any platform (assuming the reader implements all the PDF spec to the tee).

Let me tell you something. I cannot tell you what company, but I have been tasked with putting Excel files in git "because they are just zip archives with xml" and it is just a disaster. Everytime you save the document it will save certain parts of the xml code in arbitrary ways (like each image is in a list and the order of that list is random everytime), some metadata is re-written everytime like time of last modified and finally all the xml files are one single line. The git diffs are complete useless and noisy and just looking at the Excel file will cause git to consider it updated. So sure, you can use git to snapshot you Office documents... But just don't.

To be fair, this is a classical strategi in startups called "wizard of Oz prototyping" - it is used to test if there is a market for something before the tech is ready. But the tech is supposed to be created soon after and actually work...
