    It appears that the nForum on nforum.mathforge.org has gotten out of sync with the one on www.math.ntnu.no ? The latter only shows posts up until about March.

    Yup, and this new item Has the clock in nForum been set back to March 1? on ntnu.no is not showing up on mathforge.org.

    Compare http://nforum.mathforge.org/comments.php?DiscussionID=3615&page=1 and http://www.math.ntnu.no/~stacey/Mathforge/nForum/comments.php?DiscussionID=3615&page=1. The same thread appears in both versions, but the March 1 limited version is shorter.

    The old addresses are meant to automatically redirect to the new ones. Clearly, those redirections have broken for some reason and the old nForum (which I have yet to delete) is showing through.

    I’ll take a look at why the redirects aren’t working, they ought to and we want them to. But it’ll be tomorrow now. I recommend that you update your personal bookmarks to point to the mathforge address.

    Phew. Fortunately I edited the relevant file last in vim and it nicely saved a backup for me. So I’ve copied that over and the redirects are back in place.

    (However, as it was a backup, it presumably doesn’t have the latest change that I made. Unfortunately, I don’t remember what that was. Bother, bother, bother!)

    Thanks for bringing this to my attention.

    But it’ll be tomorrow now.

    It seems to be fixed right now which is much sooner than tomorrow!

    My problem is that I set up the RSS feed (using .no) a good while ago for Google Reader and it has just continued to work and took me to .org pages. HOWEVER if I click on the “nForum - All Discussion Feed” at the top of the Google Reader display it will take me to the .no discussion page when there is a difference.

    So as a warning to others - UPDATE YOUR RSS FEEDS.

    Right after posting it, I realised what had happened. I’ve now checked with the snapshots and I have the correct file reinstalled so all should be as it was.

    Since about the time when you posted this, I get to see the nForum only in pure-ASCII format.

    (Of course if this is not just on my end, you will have noticed this yourself. If not, then I am in trouble…)

    Urs, can you try doing a forced refresh of your browser? It is entirely possible that your browser is trying to load a CSS stylesheet from the old location and doesn’t know to try again (simply reloading the page isn’t always enough to force the browser to try to get all the extra files).

    • CommentRowNumber13.
    • CommentAuthorAndrew Stacey
    • CommentTimeMay 30th 2012

    Nope, was my fault again. Turns out the file I thought was the backup wasn’t and I was comparing a file against itself, whence no differences. Now I’ve found the real backup and restored it.

    You’ll probably have to force refresh the page anyway.

    Many apologies for all this hassle. I think I’m going to have to consolidate my websites as the various different systems I have for getting stuff onto the web sometimes clash.

    By the way, now the nLab seems to be down…

    • CommentTimeMay 30th 2012

    I’ve just restarted the server. There appears to be a lot of traffic on the nlab (and azimuth) and it’s just overwhelming the server. Some of it isn’t good - the color: white spambot is doing its best to leave spam (I’ve put in another block on that), but other just looks like search engines indexing the lab. Price of popularity …

    Thanks for restarting the server!

    Concerning the spam: once it was on my request that you removed a mechansim that would block everything from a long list of IP addresses. The reason was that with this block I couldn’t use connections via my USB surf-stick to log into the nnLab, because most of the IP addresses that I would be assigned this way were on this list.

    So is this the cause of much extra trouble at the moment? Just hypothetically, if you were to put that mechanism back into place, would that keep for instance that colore:white-spam away?

    Not that I am looking forward to having that block be put back into effect, but on the other hand it seems that we cannot forever hunt for spam manually. What could one do about it, in the long run?

    • CommentRowNumber18.
    • CommentAuthorAndrew Stacey
    • CommentTimeMay 30th 2012

    I don’t think that’s a significant concern. I’ve just checked the logs and found only 6 IPs that would have been blocked by that spam filter and none of them correspond to edits in the nLab. So no, that wouldn’t block the white-spam.

    In the long run, I don’t know. Maybe having user accounts at some level. Maybe links from the nLab should be on a white-list so that anyone posting a link to a URL that we’ve never seen before gets blocked until it’s registered.

    These are just random ideas, I’ve no idea whether or not any of them are feasible. That’s Jacques’ line.

    I think it may be good to have user accounts just optionally for those who decide to register their names. This way only the unregistered names are suspicious as the registered ones required password for any use (though this has drawbacks – sometimes one wants to edit something over nonsecure line, like from the library computer, this work would then drop out as these are not the situations to fill in any passwords. At least the registered people should be able to post new URLs without special effort. Well, you will feel better the threshold of tolerance when some serious action should be done, as the work involved in removing the trouble is mainly yours.

    Note that someone signing in as The User has been editing some pages. This is not exactly Spam but as some of the changes are significant it may be worth checking. (see Gram-Schmidt process: The User? at May 31, 2012 06:10:18 from 91.5.198.184)

    One thought: we don’t have spam on the nnForum, and at the same time none of us has any problems accessing it from wherever we want (it seems). Maybe if we had the same kind of login-system also for the nnLab, all problems would be solved?

    That would also take care of the problem that we have contributors of the kind that Tim points out above, who seem to be willing to make substantial contributions, but who don’t get into contact with the community here. Requiring them to login would also be a way to ask them to announce changes at the nnForum.

    Wikipedia has both registered contributors and anonymous contributors. I have friends who i would like to contact via skype and who would like the same, but registered for skype account long time ago, did not use it for long, and do not remember password or something and this makes it cumbersome enough to give up! There are MANY sites and wikis which look interesting to me, and I occasionally stumble into them and never get into the editing or their community EXACTLY because they have registration procedures (I dislike so many passwords, and many forget, even lost some reserve email accounts that way). We are registered to nnForum usually automatically from our stations; I do not feel that it makes me posting about changes made (many times I do not report, when I am busy and is not crucial, or leave for later). Higher the threshold, the common problem that so many people use nnLab but never contribute, will become just more drastic. So I think login should be optional, so that at least spam screening does not screen for our names.

    I like the idea of optionally registering names. That is probably the most complicated for Jacques to do, but if we like it best, we can still ask him about that first.
