[OpenGuides-Dev] Debian repository for OpenGuides
by Dominic Hargreaves 10 Oct '04

10 Oct '04

Hi, I've packaged the dependencies for OpenGuides that weren't already in Debian (testing/unstable). You can make use of an apt repository of them by putting the line deb http://www.larted.org.uk/~dom/debian/openguides/ unstable/ in /etc/apt/sources.list. OpenGuides itself isn't yet packaged, but I will be working on preparing a package of it in the next week or so. In the meantime, you should find that everything else should be available, so I would be grateful if Debian users running sarge or sid could test these packages. The following command should result in all dependencies of OpenGuides (0.41) being installed: # apt-get update # apt-get install libdbd-pg-perl # OR # apt-get install libdbd-mysql-perl # OR # apt-get install libdbd-sqlite-perl # apt-get install libalgorithm-diff-perl libcgi-wiki-perl \ libcgi-wiki-formatter-usemod-perl libcgi-wiki-plugin-categoriser-perl \ libcgi-wiki-plugin-diff-perl libcgi-wiki-plugin-geocache-perl \ libcgi-wiki-plugin-locator-uk-perl libcgi-wiki-plugin-rss-modwiki-perl \ libcgi-wiki-plugin-rss-reader-perl libconfig-tiny-perl libfile-spec-perl \ libgeography-nationalgrid-perl libwww-perl libmodule-build-perl \ libparse-recdescent-perl libsearch-invertedindex-perl libtemplate-perl \ libtest-mockobject-perl libtime-piece-perl liburi-perl libxml-rss-perl Once you have done this you should be able to download OpenGuides and manually install it by following the instructions in INSTALL. This testing is best done on a vanilla sarge/sid system, but especially one that hasn't had any openguides-related stuff installed on it before. Comments welcome, either to the list or me personally. You can if you wish add to http://openguides.org/dev/?node=Debian%20Package%20Bug%20Tracking but if you do please email me to let me know you have done so. Have fun! Dominic.

[OpenGuides-Dev] Node density map
by Earle Martin 10 Oct '04

10 Oct '04

Jo wrote some code (http://mappinghacks.com/openguides/) to do an SVG plot of where nodes with lat/long data are in relation to each other. I've modified it a bit to highlight stations to give an idea of scale, and here's the result: http://london.openguides.org/nodemap/nodes_with_stations.svg Stations are red, other nodes are blue. It's crude, but you can pick out several different Tube lines and see where the big clusters of nodes are. -- Earle Martin http://downlode.org/ http://purl.oclc.org/net/earlemartin/

[OpenGuides-Dev] Throttling DoS
by Paul Makepeace 09 Oct '04

09 Oct '04

IP 213.232.83.91 (Prodigy UK DSL) was hammering london.OG earlier; 5,000+hits in the last couple of hours. Any thoughts on preventing this in future? Perhaps with Apache or at the application level. It isn't the first time it's happened either, and it drives the load on the machine way up. (Not as badly as the MT comment spammers however... b*stards.) What I'd much prefer to see is for someone to come up with a workable, ideally executable, plan rather than just say 'check out mod_throttle' or whatever.

[OpenGuides-Dev] sqlite performance and migration?
by Rev Simon Rumble 07 Oct '04

07 Oct '04

Hi folks. I'm gradually hacking my Openguide installation into shape, getting some starter content in there. I'll start pushing it more publicly when I'm happy with it and think it's ready for the big bad world (and slashdotting, which is probably inevitable) Here's the (current) URL. I'll ask for an openguides subdomain when I work out what I want to call it. Comments gratefully received. http://stout.rumble.net/cgi-bin/openguides/wiki.cgi Now my question is this: how well does sqlite as my database scale? What are the caveats? According to the web site it is ACID and thus a "real" database (thought the "C" is kinda laughable since it doesn't enforce foreign key constraints). What do I need to do if I decide to upgrade to a "real" RDBMS? Is it easy to move the data from one to the other? -- Rev Simon Rumble <simon(a)rumble.net> www.rumble.net "Bore, n.

[OpenGuides-Dev] Postcodes again (UK specific)
by Kake L Pugh 02 Oct '04

02 Oct '04

Been thinking again about the postcode search issue. 1. (Getting this out of the way first.) There's a module on CPAN called Geo::Postcode which can provide the "centre of gravity" of a postcode district (eg SW6) as OS co-ords or lat-long. The author posted on the Class::DBI list and said that the data comes from jibble.org/ukpostcodes/ Now, jibble.org doesn't say where they got the data from and didn't reply to my email asking. So although it would be lovely to use this data, I don't want to rely on it and then everything falls down when someone gets heavy on the author and makes them take it off CPAN (this has happened - see Streetmap.pm). 2. The format of UK postcodes is fixed and is public domain - see http://www.royalmail.com/portal/rm/content1?catId=400044&mediaId=9200078 So we could get a crude search going by stripping off the sector and unit code and finding nodes whose postcode is "LIKE" that. In fact I have just written such a thing. However I'm not convinced this is "better than nothing" since if someone enters for example a postcode in SW6 then despite OGL having several things in W6 which are quite close to SW6 it won't return anything. I don't like the idea of a search function which gives the impression that the guide doesn't have information which it in fact does. (SEE BELOW for more on this.) 3. We could find everything in W6, find everything within 500m of everything in W6, and return the lot. This is computationally expensive and the 500m-ness is arbitrary. Also doesn't work if we don't have anything in W6. 4. We could find all the locales of everything in W6, find everything in those locales, and return them. This is cheaper, but someone adding a locale of, say, "West London" to a single node can make a simple postcode search return half the database. Also requires the guide to have data in W6. 5. We could find the postcode that's most similar to the one entered, find its locales, find everything in those locales, and return them. This suffers from the same problems as 4, but the "West London" problem will affect fewer searches. 6. We could make a formal mechanism for gathering data such as that in http://london.openguides.org/?Postal_Districts and redirect eg WC1 searches to locale searches on Euston and Bloomsbury. I quite like this idea. 7. We could stop thinking about postcode searches as being a function of distance and make them cater only for people who genuinely do want to search for "all things whose postcode begins with W6". I am not sure this kind of search would be useful. 8. We could forget about postcode searches altogether and have a locale search instead. This would be trivial to implement, but requires people to know exactly what we mean by locale, and to know what locale their base point is in in the first place. Besides, I *want* a postcode search. I want to be able to stick in my postcode and find all the stuff near me. That was just a brain dump since I was thinking about it and wanted to note it down. And here is the SEE BELOW. I'm fairly sure that at some point I found a list of which postal districts are next to which other postal districts, and I think it may even have been on the Royal Mail website. However I can't find it now. I've emailed the Royal Mail to ask but I expect I won't get a very quick or informed reply, if I get one at all, unless their helpdesk is unusually competent. Does anyone recognise what I'm talking about? Kake

[OpenGuides-Dev] Front page recent changes box
by Earle Martin 28 Sep '04

28 Sep '04

After some discussion on the #openguides IRC channel.... It has been noted recently that OpenGuides front pages are often very cluttered. Kake suggested, and I agree, that the recent changes box should be slimmed down as follows: 1) Collapse multiple instances of any given node to just one. 2) Only show node names, not change summary or editor. The actual details off the change are best left on the actual Recent Changes page (which is a "geek thing"). So, in effect, it would be "ten most recently modified nodes" (or maybe five?). Comments? -- Earle Martin http://downlode.org/ http://purl.oclc.org/net/earlemartin/

[OpenGuides-Dev] New openguide (Chester)
by David Ford 27 Sep '04

27 Sep '04

Hi, Over the last couple of weeks, I've been setting up an Open Guide for Chester, which is located at http://chesterguide.org.uk Obviously it doesn't have much content on it yet, but hopefully that will come once people know about it. If anyone spots any problems (dead links etc.) I'd be grateful if they could let me know. Thanks David

[OpenGuides-Dev] nwe project
by Martín Hernán Ferrari 21 Sep '04

21 Sep '04

Hi! I'm planning on starting a openguide for the Buenos Aires city (Argentina). I already have a draft (http://guiaba.mine.nu/cgi-bin/openguides/og), but I have some doubts and I want to share them with you: I'm concerned about language. I hope the guide to be used for locals and visitors, but specially for locals. So, english doesn't seem to be a good option. But: all the other pages in openguides are in english, including Oslo's; and the software doesn't seem to suppor multi-language. I'm not really convinced on using openguides as a platform, since the only features I see which gave me some advantage over other wiki engines are categories and locales (which can be implemented with some hack), and they aren't trated in a special way, it is the same if I put a link at the bottom of the page The rest of metadata doesn't seem to be used except to be shown in the same page (the coordinates system can't be used, since i'm outside the uk). Another important fact is that it is too slow withour mod_perl.. is there any provision for running under it? I don't want to be a flamer, just those are questions that arose when starting this project (which I had in mind before knowing openguides), and may be someone can help me....

[OpenGuides-Dev] Search engines and edit/delete pages
by James Green 20 Sep '04

20 Sep '04

Hiya. It occurs to me that there's very little point in search engines crawling certain pages of an OpenGuide - anything with "action=edit" or "action=delete" in the URL, at the very least, has no real value to someone searching for information. Unfortunately, unless I'm missing something, robots.txt syntax doesn't allow for matching on anything other than the start of the path component of a URL, which doesn't help us here. It's been suggested to me that ``<meta robots="noindex">'' tags in the <head> of a page are effective here, but I'm not sure of the best way to implement this for edit pages without implementing it for *all* pages, which would be careless. I'm thinking of something in header.tt conditional upon the requested URI containing "action=edit" or "action=delete", but before I wander off learning how to talk template::toolkit, I'd be interested to hear better suggestions -- and other values of action we might care about, I guess. The other, more complex but possibly "better" alternative, would be for someone to run with the idea mooted in this thread: <http://openguides.org/mail/openguides-dev/2004-April/000258.html> Then edit pages could be /edit/Node_Name, deletes /delete/Node_Name, and so on. This makes setting up a suitable robots.txt very simple indeed, though it makes setting up the Apache rewrite rules a) a requirement, instead of just a nice thing, and b) more complex than at present. Thoughts, comments, suggestions and the like all invited. Cheers, James. -- PGP fingerprint 3E85 0C7A FE11 42E9 A599 094D AE16 90F0 81AE 16FF, ID 81AE16FF Fremen add life to spice!

[OpenGuides-Dev] SVG on Mac OS X
by Kake L Pugh 19 Sep '04

19 Sep '04

[Crossposted: openguides-dev and london.pm] This is a call for help to anyone interested in OpenGuides or just feeling randomly helpful. A long time ago I wrote a thing to map an OpenGuide in SVG. It was cute. Since then I've swapped laptops and so I no longer have a browser that can display SVG. I would like to do more cute things with SVG, but I'm not going to get around to it unless I can actually see what I'm doing. So what I want from someone out there is foolproof instructions for viewing SVG in a browser - any browser that I don't have to pay for - on OS X. Thank you, sleep well, drink tea. Kake
