[OpenGuides-Dev] OG performance
by Paul Makepeace 20 Jun '07

20 Jun '07

Hi, I don't follow OG development but as host operator a few things are coming up. The machine's load is gradually climbing over time and some of that is OG. Despite a relatively low hit rate on OG it is consuming quite a bit of resource. If OG started taking off it would take the machine down. First up: index.cgi requires 0.35s to perform a `perl -c` syntax check. Any thoughts on putting OG on a mod_perl server? I have mod_perl running here of course and we'd need to coordinate some apache.conf stuff. Second: the supersearch.cgi gulps down CPU, often for seconds at a time. It is a frequent resident of `top` output. This isn't really acceptable. I'm going to request this feature be turned off unless an effective optimisation plan or some other way to reduce its impact here is constructed pretty soon. Sorry about this but it's encroaching on others. Third: I wonder if there's some way to instruct robots not to spider parts of your wiki. This ought to speak for itself: $ grep crawl /var/log/apache/london.openguides.org-access.log | grep 'action=edit' | wc -l 8242 $ Finally: I posted about a DoS and was wondering what the status of a solution was. http://openguides.org/mail/openguides-dev/2004-October/000542.html Cheers, Paul (any overbearing tone unintentional ;-) -- Paul Makepeace .............................. http://paulm.com/inchoate/ "If my elbow was straight, then I'll show oyu mine!" -- http://paulm.com/toys/surrealism/

openguides.org website again
by Kake L Pugh 06 May '07

06 May '07

In the absence of a redesign of openguides.org (I just haven't found the time, don't know if anyone else has?) I offer the following suggestion for fitting the Randomness Guide into the list of links: http://the.earth.li/~kake/cgi-bin/tmp/ogsite2/page It's not perfect by any means, but it's good enough, I reckon. Any objections to me committing this to svn and asking Earle to update the site? Kake

Hackfest!
by Kake L Pugh 03 May '07

03 May '07

So, it seems people are keen on a hackfest. Dom's made a meetomatic page for people to register the dates they'd be able to make: http://www.meetomatic.com/respond.php?id=ECAL07 Current possible venues are Oxford and London. Any preferences? Any offers of hosting in other towns? The focus for this hackfest will probably be bug triage and bug closing. Apologies to non-UK people - but we should see if we can work out some way for you to "attend" via IRC. Kake

Hack Day (not ours, but maybe)
by Kake L Pugh 02 May '07

02 May '07

Hello! I've signed up for this: http://hackday.org/ Basically, it's a bunch of geeks getting together in Alexandra Palace on 16th-17th June, and making things. I thought it might be cool if there were OpenGuides people there. Dom, might you be able to make it? Anyone else? One of the organisers turned up on #london.pm the other day and said not to be put off by the thing about "considered for participation" and "reviewing applications for attendance" - apparently that's mostly to put off people who're not actually involved in building interesting things and just want to come for the free booze/networking/etc. Note that I don't know if there'll be space there to do anything directly OpenGuides-related, but it might be fun anyway. This also reminded me that I've been thinking for a while that it might be about time for another OpenGuides hackathon - anyone interested? Also: I learn from the interweb that Earle is going to Montreal to talk to Wikitravel people about RDF output and how we can make OpenGuides and Wikitravel talk to each other: http://evan.prodromou.name/Journal/4_Flor%c3%a9al_CCXV Is anyone else doing anything exciting at the moment? I hear rumour of a potential OpenGuides-related talk at YAPC::EU... Kake

Who edited what
by Earle Martin 26 Apr '07

26 Apr '07

There was discussion here recently about getting some author attribution into the data. I remain opposed to the idea until we have logins, but should that happen, I'd be all for it also showing up on the page itself, as Wikitravel does it. Example: http://wikitravel.org/en/Montreal Scroll down to the page footer to see what I mean. -- Earle Martin http://downlode.org/ http://purl.org/net/earlemartin/

We haven't talked about specific formats per se; what we're mostly interested in is coordinating namespace usage. I've certainly got nothing against JSON output, and it might even be nice to offer N-Triples (http://www.w3.org/TR/rdf-testcases/#ntriples) as well. Your recent change to using templates for the output theoretically makes it very easy for us to implement. Some examples of our output in different formats using Dave Beckett's excellent "triplr" triple-converter: http://triplr.org/json;pretty/http://london.openguides.org/index.cgi?id=Roy… http://triplr.org/ntriples/http://london.openguides.org/index.cgi?id=Royal_… -- Earle Martin http://downlode.org/ http://purl.org/net/earlemartin/

Edit form changes in svn
by Kake L Pugh 25 Apr '07

25 Apr '07

The edit form changes that I mentioned previously: http://lists.openguides.org/mail/openguides-dev/2007-April/001653.html are now in svn. Basically, there are no longer any tables involved; it's all done with <div>s, which gives you much more flexibility. I'd really appreciate it if those of you with customised edit forms (Boston, OGL, etc) could have a look at it and see if it lets you do what you want to do. The new classes and things are all documented in README.CSS. If you have any trouble with it, please let me know. I'd quite like to get this released reasonably soon. Kake

RDF improvements (was: What are people working on?)

Interesting discussion, thanks for the pointer. I certainly don't agree with that John Black fellow about "claims". RFC 3986 confuses me somewhat, as it says "Fragment identifiers... [allow] an author to specifically identify aspects of an existing resource..." This seems to imply that a fragment only refers to an aspect of a resource, which sounds at odds with fragmentInXML-28 (http://www.w3.org/2001/tag/issues.html#fragmentInXML-28), which says: "In general, the fragment part of a URI may be used to refer to abstractions as well as syntactic fragments of a representation". Still, it's not really our place to try and resolve this issue here; a perfectly acceptable workaround exists in the form of the 303 redirect proposed by the resolution to httpRange-14. So that's fine, I'm happy. > I prefer slash URIs as I believe they make a clearer > distinction between a thing and a document about a thing (and 303 > redirects help avoid any ambiguity).

Would you prefer example.com/guide/Foo_Bar/rdf or example.com/guide/rdf/Foo_Bar? Also, since those would be the 303 redirects, what would they redirect to?

Aw, no, I just think it sounds kind of weak. I think maybe "a strong aversion" was a little strong, it's more of a niggling dislike. :) > > Sorry? I don't follow...
