    Flattered though I was at being promoted to an n-category cafe author, I had to change 'Roberts' to 'Corfield' at Online resources in the description of our favourite stomping ground. Someone's fingers got the better of them, I didn't look who ^_^

    I added into Online Resources (btw, people, let us please include the link to the page commented in Latest Changes in any discussion thread which mentions it, if possible, in view of possible future automatic searchability or automatic backlinks from nLab) the link to Category List archive under Forums. It is on a blog site, so it may be classfied as blog, but I kept it as forum. Others may have intelletcual reason to change my classification.

    About David, 1: why they don't promote you there ? They should, in view of your dedication to category theory !

    @ Zoran

    Definitely the categories list is a forum that should be listed. I put in a link to the homepage for the list itself, along with your link to the Gmane archives.

    I don’t suppose anybody knows any other archive for the list, hopefully one that’s threaded?

    By the way, I am (probably) the original guilty party that mixed up the Davids. It was nothing more than a careless mistake on my part. For what it is worth, I also think David Roberts would make a good addition to the list of authors :)

    As announced in http://www.math.ntnu.no/~stacey/Mathforge/nForum/comments.php?DiscussionID=1926, I have added top page math resources linked from contents. Math resources points to MO question on math resources, to a top page of links at AMS and at the 3 pages: math blogs (former Online Resources which redirects now there as quoted in Baez’s Notices survey! lab elfs could you check for web-cash bug if it happened in renaming), math institutions and math archives. This network is now a nice directory for everyday’s work.

    lab elfs could you check for web-cash bug if it happened in renaming

    You can check for yourself just by following your link above to Online Resources; you only have to ask a lab elf for help if that link doesn’t take you to the new page. It seems to be fine (possibly because a lab elf already fixed it, possibly because there was never a problem).

    Well, in the moment of renaming the old and new versions are anyway the same. The differences come up later. So you are saying I should test by artificially additionally changing the new page and then reverting it back if it is OK ? Well, OK. Thanks.

    Test by clicking the link and seeing what URI you really end up on. So click the link to http://ncatlab.org/nlab/show/Online%20Resources and discover that you end up on http://ncatlab.org/nlab/show/math+blogs really. So the redirect works; the cache bug is not present.

    It’s not a bogus link; it’s a dead link. It certainly used to work, people praised it when it worked, and I hope that it works again. It makes no sense to move it to an inappropriate category, dead or alive.

    However, there is an appropriate category for it, which we didn’t see at first because it’s on a different page, and I have already moved it there.

    I disagree that math resources is the appropriate page for this. I created it with lots of thought as just the TOP LEVEL DIRECTORY for the pages with lists of resources which are in detail listed in the nnLab. It is created like the redirect page for the four major subcategories we have (and which I created as such, where math blog is the descendant of former Online Resources)

    Hence it is well thought that all the micro-items from other sites will be in one of the above pages and the top page would not be changed until in exceptional cases. I have put however one external link to official and huge directories of immense amount and diverse/universal context of standard information – math on the web resources formerly of AMS and exceptionally only a link to MathOverflow question which also is of universal nature and covers tens of categories of content, and is also maintained by a large community. If something is just a specialized site with limited contributions than it should go to one of the other pages which are for the individual items, not into the top directory. If we start put the leaves of the tree to the base (the top level page in the big scheme) than we loose the systematics.

    Urs has added to math resources also parellel “physics resources” and philosophy what is also orthogonal to the original scheme in which math resources meant all three categories. He also listed the page only under mathematics toc. It is hard not to repeat theoretical physics institutes under mathematics and so on, so separation is not beneficial I think, so far. It just complicates maintaining the lists, and I do not see somebody enthusiastic about doing it. For example, nobody created a page which will be dedicated only for mathematics links. For example nobody created a special page for LaTeX resources and for theoretical computer science resources which are also under the scope for math blogs for example. The fact that the mantra at the time of creation of the nnLab is to dedicate to triple math, physics, philosophy is not to be taken so literally. There are other areas, and not all in this 3 areas is interesting to us. So it is not right to have the general resource page narrowed to mathematics. “math” is just a mnemo for the central content (we could put nncontent but this would be more misleading) but includes everything.

    MathOnline is (or was, and hopefully will be again) a large list like the one produced by the MathOverflow question. Maybe it fits better in math resources by individuals? It was maintained by an individual at an individual’s domain, although written (at least partially, I’m not sure how much) collaboratively.

    • CommentRowNumber25.
    • CommentAuthorzskoda
    • CommentTimeJul 16th 2012

    math resources by individuals is not about individual-maintained blogs etc. but about the repositories of material about the math of a single author. For example, Shellah’s archive may be collectively maintained, but it is about papers of a single person. I think we should prefer there only important authors and sizeable collections for the nnLab I think, otherwise it will water down into million mathematician’s webpages without use and completeness. On the other hand, he blogs and wikis are relatively rare so I think we should list them all under math blogs, even those with very low activity (particularly because the math is fragmented into areas so if one looks at one area one finds only a handful blogs).

    It's from the beginning of the Middle Ages rather than the end, but there's St Augustine's

    The good Christian should beware of mathematicians, and all those who make empty prophecies. The danger already exists that the mathematicians have made a covenant with the devil to darken the spirit and to confine man in the bonds of Hell.

    which is really referring to astrologers.
