| 06:36:18 | <gromgull> | morning #swig |
| 06:39:37 | <mhausenblas> | morning gromgull :) |
| 06:39:51 | <gromgull> | :) |
| 06:40:13 | <gromgull> | enjoying the data mining? |
| 06:47:43 | <mhausenblas> | gromgull: enjoying that the network is sort of working :D |
| 06:48:28 | <gromgull> | yeah - only about 50% packet loss |
| 06:53:19 | <mhausenblas> | wh dd yu sy, gomul? ;) |
| 06:54:43 | <mhausenblas> | gsnedders, re your SPARQL issue, maybe wanna have a look at http://bnode.org/blog/2008/07/16/sparqlscript-semantic-mashups-made-easy |
| 06:55:12 | <mhausenblas> | it's implemented and AFAIK available in ARC2 (http://arc.semsol.org/) |
| 06:55:59 | <mhausenblas> | phenny, tell gsnedders re SPARQL, see http://chatlogs.planetrdf.com/swig/2009-06-03.html#T07-54-41 |
| 06:55:59 | <phenny> | mhausenblas: I'll pass that on when gsnedders is around. |
| 07:19:24 | <grandfatha> | Hi, how can I model the following in OWL: a class A can have 3 possible datatype properties but only one can be set at any time (A hasIntValue int, A hasFloatValue float, A hasStringValue String) ? |
| 07:20:14 | <grandfatha> | is this the case for a allvaluesForm (unionOf ) restriction? |
| 07:31:51 | <Pipian> | grandfatha: Believe it's something along the lines of a restriction with maxCardinality 1 on a property that is a unionOf the other properties. But I'm not absolutely sure. |
| 07:31:51 | <Pipian> | (A would be a subclass of that restriction) |
| 07:32:59 | <grandfatha> | okay.. well I guess that would be too complicated for my code generator to map these to OO-constructs |
| 07:33:00 | <grandfatha> | thx |
| 08:22:11 | <gromgull> | ACTION wonders about smushing on data.semanticweb.org |
| 10:23:39 | <tobyink> | I asked on the swig mailing list, but haven't got a reply there (yet), so thought I'd ask here too. I'm looking for a predicate which means roughly "has quote" / "contains text". e.g. <http://www.w3.org/> ex:quote "Leading the web to its full potential" . |
| 10:23:39 | <phenny> | tobyink: 02 Jun 20:07Z <Anchakor> tell tobyink I was wondering if rather not use from sub-delims which is part of pchar, as it would be more semanticly appropriate maybe... ( http://tools.ietf.org/html/rfc3986#section-3.5 ) / or . is not much difference |
| 10:24:14 | <tobyink> | Anyone know if such a thing exists anywhere already? My web searches have drawn a blank. |
| 10:24:42 | <tobyink> | We really need a rdfs:Class/rdf:Property search engine. |
| 10:28:41 | <shellac> | tobyink: try falcons? http://iws.seu.edu.cn/services/falcons/conceptsearch/result.jsp?query=contains |
| 10:30:36 | <BenO> | tobyink, http://www.w3.org/2006/03/wn/wn20/instances/synset-quote-verb-1.rdf ? |
| 10:31:09 | <BenO> | tobyink, but I have to admit, I just searched in http://api.talis.com/stores/schema-cache/items and pasted in the first answer |
| 10:33:29 | <tobyink> | Wordnet terms can be a bit problematic. What does "wn:Person" represent - the concept of a person, or the concept of the word 'person'? What 'dc:created' date would you attach to it? The date that humans split from our nearest ancestor, or the date the word 'person' entered the English language? |
| 10:38:58 | <tobyink> | This http://dbpedia.org/property/quote might be right, but it doesn't have any domain/range info, so it's hard to tell. I should check with dbpedia sparql interface to see how it's used. |
| 10:41:10 | <tobyink> | It looks like it connects a Thing to a literal quote regarding the Thing. Whereas I want to go from an Information Resource to a literal quote taken from the Information Resource. |
| 10:44:33 | <tobyink> | shellac: thanks for the falcons link. Didn't find what I needed, but looks useful. I still think we can do better though with helping people find existing properties and classes. e.g. a nice feature would be to narrow down your search by domain or range. (And use RDFS inferencing to include subclasses of your specified domain / range classes.) |
| 10:59:26 | <tobyink> | http://open.vocab.org/terms/quote |
| 10:59:35 | <tobyink> | A:|ov:quote |
| 11:00:14 | <tobyink> | A: Usage: <http://www.w3.org/> ov:quote "Leading the Web to Its Full Potential..." . |
| 11:28:38 | <gromgull> | does anyone know about the internals of data.semanticweb.org? |
| 11:28:43 | <gromgull> | i.e. is knud here :) |
| 11:29:13 | <mhausenblas> | gromgull - what dya need? |
| 11:29:17 | <mhausenblas> | ACTION knows a bit |
| 11:29:37 | <gromgull> | I am writing the xml files for SFSW |
| 11:29:49 | <gromgull> | do I really need to specify afiliation etc. for all authors again? Surely the system should know many if not most of them? |
| 11:29:55 | <gromgull> | are they smushed somehow? |
| 11:30:33 | <danbri> | tobyink, re wordnet it depends which rdfization |
| 11:30:53 | <danbri> | my old 1.6 conversion (offline for now at least) was done as classes of things in the world |
| 11:31:03 | <danbri> | the w3c one was done as a representation of linguistic entitites |
| 11:31:08 | <danbri> | both are useful in their own way |
| 11:32:16 | <tobyink> | OK, I didn't know there were multiple Wordnet-based vocabs. (Well, I knew there were ones based on different Wordnet releases, but I thought they were both semantically similar.) |
| 11:36:12 | <gromgull> | mhausenblas: any idea? |
| 11:38:22 | <danbri> | http://lists.w3.org/Archives/Public/www-rdf-interest/1999Dec/0002.html |
| 11:38:37 | <danbri> | that was my original go at wordnet |
| 11:38:58 | <danbri> | links all crapped out of course |
| 11:52:19 | <tobyink> | Looks useful, so why offline? |
| 11:52:45 | <libby> | olden days |
| 11:53:53 | <danbri> | tobink, it was generated thru an unmaintainable perl script that scraped the commandline output of an old wordnet utility script |
| 11:53:56 | <danbri> | the w3.org copy is more stable |
| 11:54:20 | <danbri> | if i redid it for wordnet 3 today, i'd make rdfa pages from the sql db they have, or else tweak the script used for the w3 version |
| 11:54:28 | <danbri> | wordnet data is much cleaner now |
| 11:55:32 | <libby> | where's the w3c copy? |
| 11:57:24 | <danbri> | there's a Note and a namespace |
| 11:57:29 | <danbri> | .g w3c rdf wordnet |
| 11:57:29 | <phenny> | danbri: http://www.w3.org/2001/sw/BestPractices/WNET/wn-conversion.html |
| 11:57:42 | <danbri> | .g w3c rdf TR latest |
| 11:57:42 | <phenny> | danbri: http://www.w3.org/TR/rdf-sparql-query/ |
| 11:57:46 | <danbri> | nope :) |
| 11:58:06 | <danbri> | http://www.w3.org/TR/wordnet-rdf/ |
| 11:59:00 | <danbri> | ok, i need amazon ec2 help! |
| 11:59:17 | <danbri> | i have a running instance ... and a volume with all the data on it... |
| 11:59:27 | <danbri> | ...i made a snapshot of the volume, and created a new volume from that |
| 11:59:41 | <danbri> | trying to attach that to another instance now, to ensure backups can be accessed |
| 12:00:02 | <danbri> | on the main server: |
| 12:00:07 | <danbri> | i have /dev/sdf on /mnt/foafdisk type xfs (rw) |
| 12:00:31 | <danbri> | but on the other, with the copy mounted, if i try: mount -t xfs /dev/sdf /mnt/foafdisk |
| 12:00:55 | <danbri> | mount: wrong fs type, bad option, bad superblock on /dev/sdf, missing codepage or helper program |
| 12:00:58 | <danbri> | and dmsg gives |
| 12:00:58 | <danbri> | XFS: bad magic number |
| 12:00:59 | <danbri> | XFS: SB validate failed |
| 12:01:03 | <danbri> | any ideas? |
| 12:01:56 | <swh> | danbri: sorry, can't help, but how are you finding EC2? |
| 12:02:18 | <danbri> | it seems to do the business, except when i get confused and blocked like this :) |
| 12:02:25 | <BenO> | danbri, all i can say is that /dev/sdf may not be a xfs mount after all -> is a ec2 snapshotted volume the same as a normal volume? |
| 12:03:11 | <danbri> | not sure, googling around... thanks for the pounter |
| 12:03:13 | <danbri> | pointer |
| 12:03:24 | <danbri> | how can one poke at a /dev to see what kind of a beast it might be? |
| 12:03:39 | <danbri> | brw-rw---- 1 root disk 8, 80 2009-05-10 16:33 /dev/sdf |
| 12:04:01 | <swh> | you could lookup the node numbers |
| 12:04:08 | <swh> | or compare to the real disk |
| 12:05:03 | <danbri> | (all the ebs volumes and instances are in the us-east-1a region) |
| 12:05:05 | <swh> | 8, 80 is a SAN storage node |
| 12:05:13 | <BenO> | danbri, the other one is definitely /dev/sdf and not /dev/sdf1? |
| 12:07:22 | <BenO> | danbri, do you have cfdisk or fdisk with which to look at /dev/sdf |
| 12:07:29 | <BenO> | danbri, http://en.wikipedia.org/wiki/Cfdisk |
| 12:08:12 | <swh> | fdisk is just not right without the crazy interface :) |
| 12:08:29 | <BenO> | swh, heh true |
| 12:09:51 | <danbri> | see http://www.flickr.com/photos/danbri/3591468709/ and http://www.flickr.com/photos/danbri/3591468673/ |
| 12:10:07 | <danbri> | (the control panel ui from amazon web interface....) |
| 12:10:14 | <danbri> | both seem to be /sdf |
| 12:10:53 | <danbri> | since i didn't roll my own .AMI, goal is to be able to reconstruct the sites from backup as quick as possible, by having databases, /etc and a dump of all debian packages .... |
| 12:12:07 | <danbri> | re fdisk, it's a long time since i missed with such things |
| 12:12:13 | <danbri> | if i run: fdisk /dev/sdf |
| 12:12:19 | <danbri> | Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel |
| 12:12:19 | <danbri> | Building a new DOS disklabel with disk identifier 0x5113e601. |
| 12:12:19 | <danbri> | Changes will remain in memory only, until you decide to write them. |
| 12:12:20 | <danbri> | After that, of course, the previous content won't be recoverable. |
| 12:12:20 | <danbri> | Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite) |
| 12:12:34 | <danbri> | (this is on the copy ... not messing with the orig ...) |
| 12:12:35 | <swh> | that implies it doesn't have a partition table, so it wouldn't have a number |
| 12:13:11 | <mhausenblas> | gromgull: usually you'd dump from Easychair |
| 12:13:18 | <mhausenblas> | but I guess you don't have premium access |
| 12:13:47 | <mhausenblas> | anyways, I can give you the xml and you can edit by hand the XML and the run it through the conversion tool |
| 12:14:06 | <mhausenblas> | or you give it to me (the edited XML) and I do the rest |
| 12:14:08 | <gromgull> | you can give me the xml for my workshop? |
| 12:15:16 | <gromgull> | we don't have premium access, alas |
| 12:15:17 | <BenO> | danbri, hmmm... bugger. And creating copies can only be done from snapshots? |
| 12:15:25 | <mhausenblas> | as I said, there is none (unless you have premium access which means $$$) |
| 12:15:25 | <mhausenblas> | I can give you the XML from ESWC09 and you can format you input accordingly |
| 12:15:25 | <mhausenblas> | I plan to do the same for SPOT |
| 12:15:27 | <mhausenblas> | ok, look, gromgull |
| 12:15:40 | <danbri> | on the image that does have a mounted volume on /dev/sdf i also get "Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)" |
| 12:15:57 | <gromgull> | I already have the example XML though - I can just edit this for SFSW |
| 12:16:07 | <gromgull> | although if you ahve the ESWC09 XML maybe many of the authors overlap |
| 12:16:19 | <mhausenblas> | if you pay me a beer later on I'll do it for you |
| 12:16:19 | <mhausenblas> | ok? |
| 12:16:19 | <mhausenblas> | :) |
| 12:16:19 | <mhausenblas> | that would be great |
| 12:16:19 | <mhausenblas> | then hand it over |
| 12:16:37 | <mhausenblas> | ok. after lightning talk session |
| 12:16:37 | <mhausenblas> | I give you the ESWC XML dump |
| 12:16:43 | <gromgull> | but finding emails/affiliation for all the authors will be damn boring |
| 12:17:17 | <mhausenblas> | and then you may return me the SFSW dump and I take care for the rest |
| 12:17:17 | <mhausenblas> | (conversion, updating the dogfood server, etc.) |
| 12:17:17 | <mhausenblas> | yeah |
| 12:17:18 | <gromgull> | and for all PC members I guess |
| 12:17:28 | <mhausenblas> | yep |
| 12:17:34 | <gromgull> | right |
| 12:17:34 | <mhausenblas> | let's chat after the LT |
| 12:17:39 | <gromgull> | ok :) |
| 12:17:50 | <mhausenblas> | ok |
| 12:19:24 | <BenO> | danbri, which AMI are you using? same for both? and does the second one have xfs/xfsprogs installed? |
| 12:20:14 | <danbri> | same as both |
| 12:20:21 | <danbri> | didn't install xfsprogs |
| 12:21:06 | <mhausenblas> | gtg, see you all at the lightning talks ;) |
| 12:21:21 | <danbri> | installed them both, ... but same error still |
| 12:22:45 | <swh> | danbri: does the one that works have a partition table? sorry I thought that error was from the working one |
| 12:23:02 | <swh> | you could also try file-ing it, file might know what it is |
| 12:23:37 | <swh> | could be that's there's some LVM involved |
| 12:28:31 | <shellac> | danbri: (catching up) there's no partitioning involved. put fdisk away! |
| 12:29:19 | <BenO> | shellac, was just trying to see if fdisk could tell what it was |
| 12:29:35 | <BenO> | danbri, is there anything appearing in /var/log/messages where you try to mount it? |
| 12:29:55 | <BenO> | danbri, ie tail -f /var/log/messages & then try to mount? |
| 12:37:02 | <danbri> | yep the errors i mentioned earlier, bad magic number / SB validate failed |
| 12:37:40 | <danbri> | fdisk is equally confused by the happy and unhappy copies |
| 12:37:56 | <danbri> | the magic number / sb validate errors are from mount |
| 12:38:07 | <BenO> | danbri, the fdisk was just a shot in the dark :) |
| 12:38:10 | <shellac> | ignore fdisk. I think you want xfs_check, or something like that |
| 12:38:18 | <danbri> | worth a try anyway |
| 12:38:38 | <BenO> | danbri, xfs_check man page-> http://linux.die.net/man/8/xfs_check |
| 12:40:13 | <shellac> | ACTION discovers fsck.xfs does nothing |
| 12:40:28 | <danbri> | ok, there's a difference here |
| 12:40:36 | <danbri> | on the main instance with the disk mounted: |
| 12:40:51 | <danbri> | xfs_check /dev/sdf : |
| 12:40:58 | <danbri> | i get 2 lines |
| 12:40:59 | <danbri> | xfs_check: /dev/sdf contains a mounted and writable filesystem |
| 12:40:59 | <danbri> | fatal error -- couldn't initialize XFS library |
| 12:41:31 | <danbri> | vs |
| 12:41:32 | <danbri> | xfs_check /dev/sdf |
| 12:41:32 | <danbri> | xfs_check: unexpected XFS SB magic number 0x00000000 |
| 12:41:32 | <danbri> | xfs_check: read failed: Invalid argument |
| 12:41:32 | <danbri> | xfs_check: data size check failed |
| 12:41:33 | <danbri> | cache_node_purge: refcount was 1, not zero (node=0x839c670) |
| 12:41:33 | <danbri> | xfs_check: cannot read root inode (22) |
| 12:41:35 | <danbri> | bad superblock magic number 0, giving up |
| 12:42:01 | <BenO> | danbri, there is xfs_repair that might help? |
| 12:42:17 | <BenO> | see if it can repair it/fix whatever has gone wrong... |
| 12:43:55 | <danbri> | trying. it's busy looking for 2ndary superblock... |
| 12:44:16 | <danbri> | logger, pointer? |
| 12:44:16 | <logger> | See http://chatlogs.planetrdf.com/swig/2009-06-03#T13-44-15 |
| 12:44:44 | <danbri> | Sorry, could not find valid secondary superblock. Exiting now. |
| 12:45:43 | <BenO> | danbri, urgh.... thats not good news |
| 12:46:12 | <danbri> | well it's all trashable data, was just a clone |
| 12:46:18 | <danbri> | but i like it when these things are, y'know, reliable! |
| 12:46:26 | <shellac> | ACTION hops to #foaf |
| 12:46:55 | <BenO> | danbri, reliable? amazon? ..... |
| 15:07:36 | <danbri> | EC2 problems are resolved, for those following along |
| 15:07:52 | <danbri> | i made a fresh snapshot of the volume, and new volume from that snapshot; which mounted perfectly |
| 15:07:56 | <danbri> | this time it took seconds |
| 15:08:10 | <danbri> | last time many minutes, i guess it timed out for some reason and corrupted itself without realising |
| 15:09:29 | <BenO> | danbri++ good to hear it was just amazon being flakey and not an endemic issue |
| 15:09:52 | <BenO> | danbri, well, I guess flakeyness is a big issue, but it is Amazon ;) |
| 15:10:42 | <shellac> | BenO: yeah, not sure amazon being flakey is very reassuring :-) |
| 15:10:46 | <danbri> | heh well it worries me a bit, but am glad the problem was prior to creating something |
| 15:10:53 | <danbri> | during, rather |
| 15:11:02 | <danbri> | i mean, it clearly never created a usable volume |
| 15:11:15 | <danbri> | better that than it seeming to work, then dieing at the most inconvenient time |
| 15:11:28 | <BenO> | danbri, shame it didn't put its hand up and say, 'Hey, I kinda screwed that one up' |
| 15:11:30 | <shellac> | otoh danbri and libby know a couple of people there, so maybe they can get premium support |
| 15:11:37 | <danbri> | btw shellac, re xfs, i have retained no memory of ever choosing xfs over another system |
| 15:11:45 | <danbri> | though i guess i did at some point |
| 15:12:03 | <BenO> | danbri, its speedy for deleting very large files ... |
| 15:12:05 | <shellac> | as edd said, it does use it in one of the examples |
| 15:12:33 | <danbri> | yeah, probably just followed a tutorial |
| 15:12:55 | <danbri> | if in doubt, follow the crowds cos when they get burned that'll probably be google-able too |
| 15:13:24 | <shellac> | worked for the lemmings, why not foaf-project? |
| 15:30:14 | <gsnedders> | How does the MAX() function in ARQ's implementation of SPARQL work? I was hoping I could do something like http://pastebin.ca/1446321 |
| 15:30:14 | <phenny> | gsnedders: 06:55Z <mhausenblas> tell gsnedders re SPARQL, see http://chatlogs.planetrdf.com/swig/2009-06-03.html#T07-54-41 |
| 15:32:53 | <gsnedders> | hhalpin: hey. When are you back in Edinburgh? |
| 15:36:26 | <LeeF__> | gsnedders, i think it's more like SELECT MAX(?date) ... dc:date ?date |
| 15:36:34 | <LeeF__> | i.e., the function is selected out, rather than put in the triple pattern |
| 15:38:29 | <tobyink> | I think it's as per LeeF__'s suggestion - i.e. analogous to how aggregate functions work in SQL. |
| 15:40:00 | <tobyink> | That makes it pretty difficult to do what gsnedders wants without subqueries (which haven't been standardised in SPARQL yet). |
| 15:40:49 | <danbri> | lemming is now stuck with testing backups |
| 15:40:58 | <danbri> | hey everone, testing your backups is great! |
| 15:41:26 | <danbri> | seems "mysqldump --all-databases " isn't dumping enough to recreate mysql users and their passwords |
| 15:42:28 | <mattl> | danbri: what died? |
| 15:43:01 | <danbri> | nothing :) |
| 15:43:08 | <danbri> | i'm being proactive or something |
| 15:43:33 | <danbri> | writing down what you need to do to go from the backups of www.foaf-project.org to making a running ec2 instance |
| 15:44:56 | <mattl> | danbri: happy to mirror foaf-project.org |
| 15:45:29 | <csarven> | tobyink What was the URI that you had transformed http://identi.ca/notice/4621236 into RDF? |
| 15:45:43 | <tobyink> | Being proactive as a reaction to this though - <http://esw.w3.org/topic/FoafDowntime>. Reactively proactive - is that an oxymoron? |
| 15:46:24 | <tobyink> | csarven: http://buzzword.org.uk/2009/microturtle/implementation.cgi?acct=tobyink&format=text/turtle¬ice=4621236 |
| 15:46:28 | <danbri> | mattl, having offsite backups would be great! |
| 15:46:51 | <csarven> | tobyink Thanks |
| 15:47:06 | <danbri> | tobyink, well it's an improvement on the old setup, which was backed up but hard to restore quickly, esp as we didn't realise we'd been hacked for a while |
| 15:47:48 | <tobyink> | Which reminds me - I didn't have an opportunity to run my backups last weekend. Will have to do tonight. |
| 16:15:03 | <danbri> | ok |
| 16:15:41 | <danbri> | mysql> flush privileges; |
| 16:15:43 | <danbri> | I HATE THAT |
| 16:15:47 | <danbri> | you wrack your brains, and then it is so simple |
| 16:18:34 | <PovAddict> | lol |
| 16:18:48 | <PovAddict> | get postgres :) |
| 16:19:33 | <tobyink> | I've certainly always found postgresql's command line client a lot easier to use than mysql's. |
| 16:22:11 | <tobyink> | tab-completion is a big win; inline help for SQL syntax too. |
| 16:24:21 | <tobyink> | Interesting syntax idea for microturtle - when you use a CURIE the prefix becomes the default. |
| 16:24:54 | <tobyink> | e.g. [ a foaf:Person ; :name "Toby" ] :made [ a :Document ; dc:title "ttldent" ] . |
| 16:25:53 | <tobyink> | :name, :made and :Document automatically take "foaf" as a prefix because they follow the initial foaf:Person. |
| 16:25:59 | <tobyink> | Makes sense? |
| 16:26:40 | <PovAddict> | first time I used postgres i was confused by all the extra stuff |
| 16:26:56 | <danbri> | hey, what's the best scripty way to recreate a set of users from one unix box to another one? preserving whatever IDs stop file system getting confused,etc? |
| 16:27:09 | <danbri> | won't be a huge number of users anyway but still |
| 16:27:19 | <PovAddict> | danbri: copy /etc/passwd? :) |
| 16:27:47 | <danbri> | something in me screams "no..." there |
| 16:27:51 | <tobyink> | Copying /etc/password is only a first step - you normally need to create homedirs too. |
| 16:28:02 | <danbri> | though should all be ssh pubkey logins |
| 16:28:11 | <danbri> | and homedirs can be in the mounted volume |
| 16:28:26 | <PovAddict> | danbri: /etc/passwd doesn't have passwords :P |
| 16:28:32 | <tobyink> | Not these days, no. |
| 16:28:34 | <PovAddict> | passwords are stored in a different file nowadays |
| 16:28:50 | <danbri> | when there's other state somewhere, wonder about debian getting vewwy confused |
| 16:29:15 | <PovAddict> | first time I used postgres i was confused by all the extra stuff, schemas, catalogs, tablespaces... someone told me all good RDBMs have that, and MySQL is a toy engine for not having them :P |
| 16:29:19 | <tobyink> | The /etc/shadow file has passwords, if they're on the filesystem at all. |
| 16:30:35 | <tobyink> | I needed to keep a few boxes synced like this once, and just wrote a quick perl script that copied all entries with a UID > 500 from one /etc/passwd file to another. |
| 16:30:49 | <tobyink> | UIDs < 500 tend to be used by systemy things. |
| 16:31:11 | <tobyink> | So I left it to the package manager, etc to deal with them. |
| 16:31:35 | <PovAddict> | if the systemy users aren't there already, they are created when the relevant package is installed |
| 16:32:39 | <swh> | you need /etc/shadow on modern machines too |
| 16:33:03 | <PovAddict> | yeah if he wants to copy passwords |
| 16:33:17 | <PovAddict> | <danbri> though should all be ssh pubkey logins |
| 16:35:43 | <danbri> | I reckon .... grep "x:1[0-9][0-9][0-9]" /etc/passwd |
| 16:36:00 | <danbri> | ...then run adduser with each, specifying --uid and the homedir path |
| 16:36:28 | <danbri> | i mean, grep from the archived system |
| 16:36:36 | <swh> | sounds like a job for awk | sh |
| 16:36:44 | <swh> | or sed | sh |
| 16:37:21 | <danbri> | i'm scared of over-automating this, to be honest! i'd rather have a 2 page readme |
| 16:37:27 | <danbri> | it isn't supposed to happen often |
| 16:37:44 | <PovAddict> | type the user names and IDs by hand then? :) |
| 16:39:39 | <danbri> | yeah, pretty much |
| 16:40:01 | <danbri> | btw any rdflib OSX users know how to suppress this? /Library/Python/2.5/site-packages/rdflib-2.4.0-py2.5-macosx-10.5-i386.egg/rdflib/sparql/bison/SPARQLEvaluate.py:196: DeprecationWarning: There is the possibility of __repr__ being deprecated in python3K ... combinationLambda = 'lambda(i): %s'%(' or '.join(['%s'%mapToOperator(expr,prolog,combinationArg='i') for expr in reducedFilter])) |
| 16:40:08 | <danbri> | or fix it, even? :) |
| 16:41:37 | <PovAddict> | ARGH any idea how i can check ehat stupid app is grabbing the keyboard on X? |
| 16:42:15 | <PovAddict> | oh |
| 16:42:17 | <PovAddict> | g'damn it |
| 16:42:39 | <PovAddict> | ACTION needs to see what's up with this keyboard cable -.- |
| 16:42:52 | <PovAddict> | ACTION is still glad he can send emergency IRC messages from his ipod |
| 16:44:36 | <gsnedders> | LeeF, tobyink: Thanks |
| 19:28:18 | <kwijibo> | is there a datatype URI for fahrenheit ? |
| 19:37:10 | <KjetilK> | hmpf |
| 19:37:19 | <KjetilK> | ACTION hands kwijibo the SI system ;-) |
| 19:37:45 | <kwijibo> | .g SI system temperature |
| 19:37:46 | <phenny> | kwijibo: http://en.wikipedia.org/wiki/SI |
| 19:38:00 | <KjetilK> | kwijibo, kelvin |
| 19:38:02 | <KjetilK> | :- |
| 19:38:07 | <KjetilK> | errr, :-) |
| 19:38:43 | <kwijibo> | ACTION is amenable, but hands KjetilK yahoo weather rss :) |
| 19:38:51 | <KjetilK> | :-) |
| 19:39:56 | <KjetilK> | BTW, did you have any progress on the summitpost stuff? |
| 19:40:19 | <kwijibo> | i've got a scraper of sorts together for the routes pages |
| 19:41:02 | <KjetilK> | ok, cool |
| 19:41:14 | <kwijibo> | i'm trying get weather forecasts into RDF now so I can plug it into climbing areas :) |
| 19:41:36 | <kwijibo> | unfortunately I don't really know much about the domain |
| 19:41:36 | <KjetilK> | ah, then yr.no is a really good resource |
| 19:41:51 | <KjetilK> | actually, I'm hoping to get time to get them to do it |
| 19:42:19 | <KjetilK> | you get XML dumps from there, but they are not really very suitable in their current form as Linked Data |
| 19:42:32 | <kwijibo> | that would be cool :) |
| 19:42:36 | <KjetilK> | very |
| 19:43:31 | <KjetilK> | BTW, I got the names and nicks of the key people at summitpost, but not their emails |
| 19:43:45 | <KjetilK> | we could send them a PM on the site though |
| 19:43:49 | <kwijibo> | where do they live on irc ? :) |
| 19:43:57 | <KjetilK> | hehe |
| 19:44:19 | <KjetilK> | summitpost nicks, I guess... :-) |
| 19:44:55 | <KjetilK> | summitpost should be linked to geonames |
| 19:46:06 | <KjetilK> | then, I'm hoping they will link yr.no to geonames, problem solved :-) |
| 19:46:43 | <kwijibo> | would you need to query geonames for the right uri for each place ? |
| 19:47:30 | <KjetilK> | hmmm, I don't think so, yr.no allready uses geonames for the coordinates of the world |
| 19:48:02 | <kwijibo> | i would form the summitpost side though? |
| 19:48:05 | <KjetilK> | it is just for Norway it sucks, since it uses proprietary data for Norway |
| 19:48:07 | <kwijibo> | *form the |
| 19:48:20 | <kwijibo> | *from the |
| 19:48:21 | <KjetilK> | yeah, right now, I guess |
| 19:48:27 | <kwijibo> | i was thinking of using http://placetime.com/geopoint URIs for places I have lat and long for |
| 19:49:05 | <kwijibo> | but not sure if that really solves it |
| 19:49:10 | <KjetilK> | but I guess we might be able to persuade the summitpost guys to create a UI for people to add their mountains to Geonames with a URI |
| 19:49:27 | <kwijibo> | because the lat and long would need to be exactly the same for them to match |
| 19:49:51 | <KjetilK> | yup |
| 19:49:57 | <kwijibo> | i mean the lat/long from the forecast would need to be the same as the lat/long from summitpost |
| 19:50:59 | <KjetilK> | yeah, but if you could somehow map the summitpost URIs to geonames URIs it would solve the problem too, no need for lat/long |
| 19:51:17 | <kwijibo> | yeah |
| 19:52:05 | <kwijibo> | maybe i could put geonames into a store, and add some geonames triples to the climb location data in a second stage |
| 19:52:14 | <kwijibo> | in batches |
| 19:52:37 | <kwijibo> | well, I'm sure it's solvable somehow in a not too inefficient way :) |
| 19:52:45 | <KjetilK> | hehe |
| 19:53:01 | <KjetilK> | well, you could use the geonames ontology to only ask for mountains |
| 19:53:40 | <KjetilK> | and map the summitpost mountain coordinates to a nearby geonames mountain with a similar name |
| 19:53:58 | <KjetilK> | problem is that the geonames coordinates are often pretty bad... |
| 19:54:18 | <kwijibo> | what do you think of this as a publish pattern for forecasts ?: :Place weather:forecast <http://weather.dataincubator.org/forecasts/now/Snowdon> . |
| 19:54:32 | <kwijibo> | then |
| 19:55:05 | <kwijibo> | <http://weather.dataincubator.org/forecasts/now/Snowdon> redirects to <http://weather.dataincubator.org/forecasts/2009-06-03/Snowdon.rdf> |
| 19:55:06 | <KjetilK> | it would probably be a good thing to have summitpost mountain maintainer link directly to geonames, it would mean an explicit link and geonames could inherit the coordinates |
| 19:55:20 | <KjetilK> | yup, that'd be nice! |
| 19:55:28 | <KjetilK> | very webarchy too |
| 19:55:42 | <kwijibo> | then would there need to be some link back to <http://weather.dataincubator.org/forecasts/now/Snowdon> from that document ? |
| 19:56:24 | <KjetilK> | I didn't quite understand that question |
| 19:56:30 | <kwijibo> | because when you deref a URI, you look for it as a subject in the document you get back |
| 19:56:43 | <kwijibo> | oops, train, gotta go |
| 19:56:50 | <KjetilK> | hehe |
| 19:57:10 | <KjetilK> | ACTION hopes that doesn't mean kwijibo was run over by one... |
| 19:57:32 | <mischat> | http://sameas.org/ |
| 19:58:13 | <mischat> | D: | "SameAs" interlinking the Web of Data |
| 19:58:42 | <PovAddict> | KjetilK: * kwijibo has quit IRC (Connection reset by train) |
| 19:58:53 | <kwijibo> | :) |
| 19:59:08 | <PovAddict> | kwijibo: you missed this |
| 19:59:08 | <PovAddict> | [16:57] * KjetilK hopes that doesn't mean kwijibo was run over by one... |
| 20:00:03 | <kwijibo> | :) |
| 20:00:42 | <KjetilK> | :-) |
| 20:00:43 | <kwijibo> | yeah, gotta go onto one, not out from under one |
| 20:01:25 | <kwijibo> | KjetilK: what I mean is, I want to have URIs like <http://weather.dataincubator.org/forecasts/now/Snowdon> to point to with weather:forecast which will always redirect to the latest forecast |
| 20:01:40 | <KjetilK> | yeah, I guess it is a good idea that the URI you dereference is in the document, but I haven't thought to carefully about that |
| 20:02:20 | <kwijibo> | so i wonder what the relationship is between <http://weather.dataincubator.org/forecasts/now/Snowdon> and <http://weather.dataincubator.org/forecasts/2009-06-03/Snowdon> |
| 20:03:05 | <kwijibo> | my first thought was something like dct:latestVersion - except it isn't a version, it's a different forecast |
| 20:06:59 | <KjetilK> | right, I don't know, any other takers? |
| 20:10:26 | <kwijibo_> | d/c by train again :p |
| 20:11:09 | <PovAddict> | train ran over the cat5? |
| 20:12:12 | <kwijibo_> | anyone know anything about weather ? what is 'rising' ? |
| 20:12:24 | <kwijibo_> | (http://weather.yahooapis.com/forecastrss?p=UKXX0896&u=c) |
| 20:13:54 | <MacTed> | kwijibo - "rising" would usually refer to "barometric pressure" |
| 20:14:42 | <kwijibo_> | ah, right, of course :) thanks MacTed |
| 20:15:33 | <kwijibo_> | the weather feed has both pressure and rising - how do they relate ? |
| 20:17:21 | <MacTed> | hrm. without yet looking at the data, pressure is probably a number, while rising ... hm. |
| 20:17:53 | <kwijibo_> | i dunno - both have "0" |
| 20:22:07 | <MacTed> | ah! if you look at the "full report" linked from the feed, I think you'll figure it out |
| 20:22:41 | <MacTed> | pressure is absolute current measure (in millibars); rising is falling/steady/rising (presumably -1/0/+1) |
| 20:22:53 | <MacTed> | see http://weather.yahoo.com/forecast/UKXX0896_c.html |
| 20:25:19 | <kwijibo_> | ah! :) |
| 20:26:40 | <MacTed> | <-- repository of occasionally useful trivia ;-) |
| 20:27:50 | <kwijibo_> | hmmm MacTed any idea how they calculate 1016mb form that data ? |
| 20:27:52 | <kwijibo_> | *from |
| 20:28:39 | <kwijibo_> | I don't get it |
| 20:28:44 | <kwijibo_> | it has <yweather:units temperature="C" distance="km" pressure="mb" speed="kph"/> |
| 20:29:11 | <kwijibo_> | and <yweather:atmosphere humidity="67" visibility="9.99" pressure="0" rising="0" /> |
| 20:29:26 | <kwijibo_> | so i would presume pressure is 0 mb ? |
| 20:29:37 | <MacTed> | I think they're not transforming properly, so the feed doesn't actually carry everything the website displays |
| 20:29:38 | <kwijibo_> | but in the html page, they say 1016mb |
| 20:29:53 | <kwijibo_> | hmm, quite possible |
| 20:30:27 | <kwijibo_> | weather.yahoo.com-- :p |
| 20:31:57 | <MacTed> | also, I think many (most? all?) people getting the feed won't notice -- because that data isn't in an HTML rendered segment |
| 20:33:33 | <kwijibo_> | also quite possible |
| 20:34:54 | <kwijibo_> | i don't see anywhere to give them feedback .. |
| 20:43:18 | <kwijibo_> | ACTION off for a bit to find 'lectricity and shelter |
| 20:44:25 | <PovAddict> | rising might mean temperature too |
| 20:44:27 | <PovAddict> | I guess |
| 20:44:32 | <MacTed> | yeah... I bet yahoo would handoff complaints to Weather.com, so you might just look there |
| 20:44:52 | <MacTed> | PovAddict - given that it's in the atmosphere segment, I'm betting against temperature |
| 20:45:02 | <PovAddict> | ah well I didn't look at context :] |
