[10:26:43] <piasdom> g'mornin all
[10:27:18] <piasdom> i got an email yesterday from the forum, so i guess it's just slow to start
[11:27:35] <christel> [Global Notice] Hi all, we appear to be having some connectivity issues with our main US hub, as a result of this we are temporarily without services, if this affects your channel please contact staff in #freenode for assistance. We're looking into the issues as we speak. Thank you for your patience.
[12:15:31] <christel> [Global Notice] Hi all, we're having some major issues with connectivity at the DC hosting one of our hidden hubs, I'm going to re-route around it, which will cause about twice as much noise as the splits already made. Apologies for the inconvenience.
[16:42:30] <cradek> hi seb
[16:43:11] <seb_kuzminsky> morning!
[16:43:22] <seb_kuzminsky> glad you made it home safe & sound
[16:43:28] <cradek> yes - wow are we going to get the snow today
[16:43:36] <cradek> it would have been a serious mistake to wait a day
[16:43:45] <seb_kuzminsky> yes it would have! winter's here!
[16:44:07] <cradek> they're saying 10-14" over most of the state which is pretty uncommon
[16:44:09] <seb_kuzminsky> oof
[16:44:23] <cradek> whee :-)
[16:44:32] <cradek> I checked and I have enough coffee for several days
[16:44:37] <cradek> haha
[16:44:40] <JT-Work> wow if only you were a kid again it would be fun
[16:44:51] <cradek> JT-Work: I never quite grew up...
[16:45:28] <seb_kuzminsky> today is an auspicious day... birthday of eli whitney jr, inventor of the milling machine
[16:45:35] <JT-Work> I did give up a few things but did not quite grow up either
[16:45:59] <JT-Work> I moved the Z and X axis on the Hardinge last night :)
[16:46:16] <cradek> are you retrofitting it, or leaving it alone?
[16:46:22] <cradek> seb_kuzminsky: what should we do to celebrate?
[16:46:53] <seb_kuzminsky> huddle under a blanket in front of the fireplace & drink coffee?
[16:47:20] <seb_kuzminsky> sketch a garage floor in cad and try to free a 6x6' square?
[16:47:50] <cradek> I'll measure and take pictures and stuff today
[16:48:29] <cradek> I'm not sure the drawing I sent you is right.
[16:49:20] <JT-Work> it looks like it will be a make over with EMC but robh and I are still trying to see if the original control will work
[16:49:52] <cradek> that's a hard choice. I've been there.
[16:50:16] <JT-Work> it looks like the PLC optos might be out... everything else seems to work
[19:13:21] <seb_kuzminsky> can anyone else get to linuxcnc.org?
[19:14:26] <LawrenceG> 64 bytes from apache2-route.dinero.dreamhost.com ( icmp_seq=23 ttl=52 time=74.3 ms web site comes up as well...
[19:15:44] <seb_kuzminsky> maybe my internet "service" provider is hosed again
[19:16:03] <SWPadnos> they provide you with an internet that needs service
[19:16:21] <SWPadnos> it works from here as well, FWIW
[19:19:09] <skunkworks_> works here also.. You should probably reboot your computer.... ;)
[19:19:54] <seb_kuzminsky> works here too now - maybe my isp rebooted itself
[20:05:06] <micges> jepler: around?
[21:05:10] <jepler> micges: what's up?
[21:05:35] <micges> why did you spilt up arcs in opengl preview to lines?
[21:05:43] <micges> performace?
[21:05:52] <alex_joni> opengl doesn't do arcs?
[21:06:02] <jepler> alex_joni is right; opengl does not have an arc primitive
[21:06:21] <alex_joni> it's all lines and vertexes
[21:06:31] <micges> gluPartialDisk is too slow?
[21:07:57] <alex_joni> you need to rotate the partial disk
[21:08:03] <micges> I know that all and I've done opengl preview and I wonder why is it so slow (it uses gluPartialDisk instead of splittong arcs to lines)
[21:08:33] <jepler> gluPartialDisk does the same thing, approximately
[21:10:17] <jepler> i.e., it makes repeated calls to glVertex* with different points calculated by sin() and cos()
[21:10:44] <micges> jepler: so you don't know speed difference?
[21:10:46] <cradek> we have helixes, not just arcs
[21:12:41] <jepler> I can't imagine that the interpreted Python is faster than the mature C code of libglu
[21:13:03] <jepler> cradek's point is an important one too
[21:17:02] <micges> thanks guys
[21:35:14] <micges> good night
[21:41:43] <aystarik> guys, I have code, which splits arc to different number of line segments depending on deviation of each from arc. Would it be benefitial to integrate it to AXIS? It's not complex at all...?
