Could maps be centred and scaled
by Andrew Black - lists 27 Aug '08

27 Aug '08

I have a suggestion concerning maps (eg map of all points in a category). I would like to get the maps to be centred and scaled. For example, in the following, all the points are off the displayed map. http://london.randomness.org.uk/wiki.cgi?action=index;format=map;index_type… The following is a quick demo to play with http://www2.black1.org.uk/~andrew/map/exp_bounds.html Click on a few points, hit "Reposition map" then repeat. In practice - you might want to make it configurable for the user - apply a minimum zoom (eg my demo produces a very large scale map if you give a single point) What do people think. Andrew

After the pubmeet
by Dominic Hargreaves 03 Jul '08

03 Jul '08

Thanks to those that came to the pub - it was a fun afternoon and good to talk to people and get them involved in OpenGuides/meet new people etc. I've dumped my scribblings onto the wiki page: http://dev.openguides.org/wiki/Anniversary and implemented the Akismet plugin idea (after returning home with a bunch of spam moderations to attend to...) http://dev.openguides.org/browser/sites/oxford.openguides.org/lib/OpenGuide… Very rough but something I'd like to clean up and include into the distribution as a way of making the spam problem Someone Else's Problem. Cheers, Dominic. -- Dominic Hargreaves | http://www.larted.org.uk/~dom/ PGP key 5178E2A5 from the.earth.li (keyserver,web,email)

OpenGuides (in)efficiency
by Kake L Pugh 03 Jul '08

03 Jul '08

Summary: I think I know why OpenGuides has a habit of occasionally taking over servers. If you've experienced problems with occasional ridiculously high load averages, take a look at the Action paragraph below. Action: In the short term, I suggest that anyone who's been having trouble with OpenGuides taking over their machines should comment the per-user RSS feed links out of userstats.tt - copy it to your custom_templates directory and either delete everything between [% IF username %] and the next [% END %] statement (inclusive), or change [% IF username %] to [% IF username AND 0 %] - both will have the same effect. Details: I suspect that I have at last found out the thing that makes OpenGuides take people's servers over. It's the per-user RSS feeds, which are usually linked from e.g. http://cambridge.openguides.org/wiki/?username=Kake;action=userstats The problematic feeds are those which omit minor edits, and they're only a problem on large guides (Cambridge is fine, RGL is not). The reason for this is that they effectively select _everything_ from the database and then winnow it down. When a spider is hitting one of these feeds every second... I think you can see where this is going, and it's not pretty. The reason this has gone unnoticed for so long is that (a) nobody really uses these feeds anyway, so they only get accessed by spiders etc, and spiders aren't going to email us and say "hey, this link is very slow", and (b) these feeds are the only thing in OpenGuides that use "last n changes" as a selection criterion - Recent Changes uses "last n days", which is much more efficient. The root problem is with the _find_recent_changed_by_criteria method in Wiki::Toolkit::Store::Database, specifically the "metadata_wasnt" parameter in combination with the "limit" one. I am working on a rewrite of this method to make it more efficient, but this is going to require some thinking and hence some time. Kake

Leaving
by Earle Martin 30 Jun '08

30 Jun '08

Following a conversation that I just had on the IRC channel with Kake and Christopher Schmidt, it seems my sole remaining interest area in the project (RDF functionality) is no longer of interest to other users and developers of OpenGuides. Therefore I am withdrawing from the project. I will relinquish the domain name and website hosting to whoever wishes to take over it - please mail me offlist. I wish OpenGuides good luck in the future. -- قبائلَ صوتي – على صمتها Earle Martin | http://downlode.org/

Universal edit button
by Rev Simon Rumble 26 Jun '08

26 Jun '08

Apparently there's now a universal edit button, embedded in Wiki pages in a manner similar to RSS: http://universaleditbutton.org/Universal_Edit_Button There's a Firefox extension to enable it, but I imagine it'll end up in the browsers eventually. -- Rev Simon Rumble <simon(a)rumble.net> www.rumble.net The Tourist Engineer Because geeks travel too. http://engineer.openguides.org/ "A conservative is a man who believes that nothing should be done for the first time." - Alfred E Wiggam

Robot deterrence
by Kake L Pugh 25 Jun '08

25 Jun '08

There are a number of OpenGuides page types that web spiders don't really need to index, and we have code to stop them doing it, e.g. http://dev.openguides.org/changeset/573 http://dev.openguides.org/changeset/1132 However, it doesn't seem to be working. See for instance: http://london.randomness.org.uk/wiki.cgi?action=list_all_versions;id=Locale… which if you view the source does indeed have <meta name="robots" content="noindex,nofollow" /> in the <head>. But from the Apache logs: 66.249.67.153 - - [25/Jun/2008:14:59:00 +0100] "GET /wiki.cgi?action=list_all_versions;id=Locale%20IG9 HTTP/1.1" 200 3151 "-" "Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)" Am I missing something obvious?

5th anniversary meet, Sat 21 June, Oxford
by Kake L Pugh 20 Jun '08

20 Jun '08

A decision has been made! The 5th anniversary meet will be in Oxford on Saturday 21 June, starting at lunchtime and continuing into the evening until people need to head home. Dom and Socks are working on figuring out a suitable venue. Please put this date in your diaries now! You can also start inviting other people along - I think Ivor had some thoughts on this. I'll be publicising it on the RGL livejournal community. Kake
