nice, but which ones support CORS headers
12:21:05 [webr3]
and likewise HTTP caching via ETag or Last-Modified
13:22:59 [ericP]
presbrey, python-test worky now
13:24:28 [ericP]
a configure-generated config.h file was in the way, and i had to back off on the compiler pedantry 'cause 4.4.4 is newer and capable of being more persnickety than mine
13:24:49 [ericP]
(it was whining about using #warning, which is widely deployed but non-standard)
13:25:28 [ericP]
also had to hide a couple initializers from swig 'cause it doesn't really grok all of C++ (well, C in this case)
13:27:34 [timbl]
webr3, good questions ... a script could answer them
13:27:45 [timbl]
Where is the database of the lod datasets?

ericP, just an update to syntax. not functionality, eh
15:47:54 [presbrey]
can you look at my lua bindings to swobjects?
15:48:48 [presbrey]
I had to use redland yesterday for my lighttpd-embedded Lua SPARQL server: http://bit.ly/d4nFNo
15:48:55 [presbrey]
so of course there's no SPARQL update ;)
15:56:26 [presbrey]
timbl, we should get a proper SSL certificate for tabulator.org
15:59:33 [lkagal]
lkagal (~lkagal@30-6-179.wireless.csail.mit.edu) has joined #dig
16:05:49 [timbl]
yes .. where from
16:05:53 [timbl]
Gandi.net?
16:06:55 [presbrey]
sure, are certs cheaper in euros these days?
16:15:22 [timbl]
The systeam folks seem to trust gandi
16:21:20 [melvster]
LMK if you need a token to transfer the domain to one of you guys ... I can initiate that
16:21:57 [presbrey]
fine with me. do they take CSRs or what?
16:22:10 [melvster]
ill have a look
16:22:20 [melvster]
oh wait ... u were talking about gandi ...
16:22:41 [presbrey]
yeah timbl, sorry melvster, I'll email you a CSR for gandi?
16:24:34 [presbrey]
CSR off to you timbl, lunchtime, cya soon
16:26:55 [melvster]
presbrey: i sent you a transfer auth code in case you need it

jie, are you around ?
17:09:20 [ericP]
presbrey, what's needed for the lua bindings?
17:09:38 [ericP]
i noticed that you put the Makefile down in swig/lua
17:09:54 [ericP]
you could copy (and adjust paths) that to /Makefile
17:10:14 [ericP]
if you search for perl|java|python, you'll see how i did the ohters
17:20:33 [marisol]
marisol (~marisol@31-34-161.wireless.csail.mit.edu) has joined #dig
17:32:56 [presbrey]
ericP, just try running make
17:33:00 [presbrey]
in the swig/lua folder
17:46:43 [ericP]
presbrey, is there a liblua-dev package around, maybe liblua5.1-0-dev?
17:46:55 [presbrey]
it would be called lua-devel
17:47:04 [ericP]
what's the incantation?
17:47:11 [presbrey]
yum install -y lua-devel
17:47:32 [presbrey]
should give you 5.1.4
17:48:16 [ericP]
i probably have to tell g++ where to find e.g. lauxlib.h . how do i interrogate the contents of lua-devel?
17:48:25 [presbrey]
rpm -ql lua-devel
17:51:25 [ericP]
check out $(make lua-test) from sparql11/
17:52:03 [ericP]
swig gen's some stuff unpallatable to lua. any leads?
17:54:18 [marisol]
marisol has quit (Quit: marisol)
18:00:58 [presbrey]
uh
18:01:10 [presbrey]
I used it with librdf
18:01:15 [presbrey]
and it was pallatable
18:02:04 [presbrey]
eg. traits is not a template, you mean?
18:02:28 [lkagal]
lkagal has quit (Quit: lkagal)
18:02:43 [presbrey]
the SAXhandler error and warning functions can be hacked out I assume

so I have an RDF model cache in Lua now
18:38:00 [presbrey]
gets my implementation from 4.5 queries/sec up to 11.3 using ApacheBench
18:38:55 [presbrey]
250% improvements are always nice :)
18:39:37 [presbrey]
oops, 2.5x but only 150%
18:42:24 [mcherian]

presbrey, cool re 150% improvement by moving to lua !
19:43:19 [presbrey]
oh that wasn't lua vs. python, twas my own optimization within lua
19:43:56 [presbrey]
a simple RDF model cache by URI
19:46:37 [presbrey]
it is cool though
19:46:50 [presbrey]
ericP, do you know how those SWObjects Lua errors originate?
19:59:53 [lkagal]
lkagal has quit (Quit: lkagal)

mcherian (~mathew@30-6-25.wireless.csail.mit.edu) has joined #dig
20:51:44 [presbrey]
timbl, you should need the tabulator.org CSR I sent to get a certificate from gandi
20:52:14 [presbrey]
the CSR contains the public key for tabulator.org corresponding to the private stashed on the dig server
20:53:09 [oshani]
oshani (~oshani@31-35-182.wireless.csail.mit.edu) has joined #dig
20:53:45 [presbrey]
among other things you can see by `cat tabulator.org.req | openssl req -text`

'Staring scan...', 'dummyObjectTree', 'seen', ...?
21:50:16 [presbrey]
wow rdflib.js is huge
21:50:22 [presbrey]
my sparqlUpdate.js got rolled into rdflib.js
21:50:33 [presbrey]
so why does sparqlUpdate.js still exist?
21:58:53 [ericP]
presbrey, re Lua errors, I knocked out a few by adding a " || defined(SWIGLUA)" to SWObjects.i
21:59:40 [presbrey]
cool ericP
22:00:00 [presbrey]
Tabulator is dump'ing megs into my X11 session log
22:00:02 [ericP]
haven't worked out how to deal with va_list (the last four errors)
22:00:10 [presbrey]
so I got distracted, hehe
22:00:44 [lkagal]
lkagal has quit (Quit: lkagal)
22:00:58 [timbl]
yes tabulator has got too many dump() statemnts
22:01:51 [presbrey]
can't we get some if (!DEVEL) { dump = function() {} }
22:02:11 [presbrey]
also see my question about the status of sparql update
22:02:35 [presbrey]
I'm trying to get the bug tobyink reported fixed
22:03:12 [presbrey]
ericP, do you want to put that new syntax into algae too?
22:03:31 [presbrey]
otherwise the 2007 wiki will break when I push the 'INSERT DATA' patch to tabulator
22:03:46 [presbrey]
or timbl, can we leave the 2007 wiki behind?
22:07:02 [ericP]
i haven't had my fingers in algae for a long time
22:11:09 [presbrey]
