There are quite a few links in the network (148 when I'm writing this, mainly on Cross Validated, Mathematics and MathOverflow) to the Virtual Laboratories in Probability and Statistics hosted at https://www.math.uah.edu/stat/ which contains material about probability and stochastics. The material is still available and is now called Random. Links like http://www.math.uah.edu/stat/expect/Spaces.html (from this randomly chosen post) redirect to Random's homepage, but it would be a lot better if visitors were directed to the page itself.

I have a script which can do this, but this time the substitution is so straightforward that the mass link updater tool can be used by staff members to fix them at once, without bumping the affected posts to the front page. All it needs to do is find www.math.uah.edu/stat/ and replace it with www.randomservices.org/random/.

I have swapped out the URLs for all the links that I could find, in both posts and comments, except for a handful of exceptions that I couldn't touch due to length (changing the URL would have pushed the comment beyond the maximum length, and I don't want to take editorial liberties to make them fit).

Here are the posts (both questions & answers) and comments I've found on each site, and fixed or not fixed:

Site # of posts changed # of comments changed # of comments ignored
Cross Validated 68 38 3
Mathematics 94 63 3
Math Overflow 6 3 0
Physics 2 1 0
Stack Overflow 6 4 0

This adds to more than 148 because the search only yielded questions but, in some cases, there were multiple answers that contained relevant links as well.

I know the Ids of the comments I left alone, and during business hours I will look more closely to see if I can do something creative to make them fit without affecting substance.

    Thanks a lot for the quick fix! Now I'm wondering why that search didn't include answers...

    @Glorfindel I think in cases where a question and at least one of its answers is returned by the search, you only get one result?

    That would be a plausible explanation, but this search seems to suggest otherwise. Well, without another example, it will be hard to fix the bug that caused it ...

    @Glorfindel Well, something was definitely funky with your search anyway, you said there were 148 results (and I believe you) but when I browsed through them to see what we were looking at, there were 4 pages (@ 30 per page), and every single post except this one was from Cross Validated. So I was only seeing <= 120 results. I cleaned up one site at a time, starting with Cross Validated, and after a few minutes suddenly the search re-populated with the results from the other sites. I don't know if I can explain that behavior either, except that perhaps 148 wasn't accurate either.

  • That's a known bug ...

    @Glorfindel Yes, nav/pagination is broken, which leads me to mistrust my count of 120, but I still ended up modifying more posts than even your search yielded, which was more than mine yielded. I trust the database results more than the search in any case. :-)
