[00:16:27] <seb_kuzminsky> cool!
[00:16:44] <seb_kuzminsky> it's always kind of magical to see real-world parts made from programs
[00:17:57] <skunkworks> it has been run virtually 1000's of times :)
[00:18:15] <seb_kuzminsky> heh yep
[00:19:52] <skunkworks> that is the coarse one. there is one with finer step-over
[00:21:13] <skunkworks> I didn't have a long enough endmill to do the whole program
[00:21:20] <skunkworks> Ball
[00:21:55] <seb_kuzminsky> hey no swearing in the channel
[00:23:15] <skunkworks> looks like there might be slight backlash in z.. it cuts slightly deeper one one side of the belly vs the other
[00:24:02] <skunkworks> you can really see it when you are only cutting on the very tip of the ball endmill

[05:06:13] <seb_kuzminsky> was that exempted from the lawsuit threat?
[05:06:42] <seb_kuzminsky> hmm, ok
[05:14:32] <seb_kuzminsky> update_ini crashes on my lathe test ini file

[13:10:09] <seb_kuzminsky> hm, all the rtai buildslaves failed the new lathe test
[13:31:36] <seb_kuzminsky> this is the first test to use simulated homing, i think
[13:31:53] <seb_kuzminsky> the homing takes much, much longer (in wall-clock time) on rtai than it does on uspace, not sure why
[13:31:57] <seb_kuzminsky> but that's why it's failing
[13:33:10] <seb_kuzminsky> if i increase the homing timeout from 10 to 30 seconds, it suceeds, and then the test passes

[13:44:15] <jepler> I wonder how rtai realtime behaves when it's missing deadlines
[13:45:53] <jepler> on uspace, sleeping with clock_nanosleep(CLOCK_MONOTONIC, TIMER_ABSTIME), if the system goes out to lunch for a second, a 1ms thread will run 1000x as fast as possible when it comes back
[13:46:05] <seb_kuzminsky> it might be because i have a base thread
[13:46:12] <seb_kuzminsky> it doesnt do anything, but it still takes time

[15:24:43] <jepler> we get well over one nine of reliability from our hosting. yay Chris.
[15:24:57] <cradek> :-P
[15:25:18] <cradek> it's really rare for an outage to outlast my UPS
[15:25:37] <cradek> and more rare for a power supply to be bad after an outage
[15:25:50] <jepler> everything is going to hell in Lincoln. electricity, internet, roads. it must be the end of western civilization
[15:26:02] <cradek> and more rare for the replacement power supply I was carefully keeping ready to not have enough sata connectors
[15:26:10] <jepler> and now, i learn, psus
[15:26:23] <cradek> fortunately I have sidecutters and plenty of wire nuts

[16:52:39] <jepler> Subject: [website PATCH] 4.1 is a longterm kernel.
[16:52:47] <jepler> I'll be maintaining 4.1 for the next two years, proving that after a
[16:52:51] <jepler> decade of doing stable kernels, I still do not know any better.

[16:53:14] <ssi> lol
[16:53:19] <jepler> I wonder if Debian will pick 4.1 for stretch
[16:54:40] <jepler> 4.1-rt seems like a great kernel for uspace realtime with fpgas

[17:14:00] <PCW> Yeah. dont know if you noticed the LCNC forum7I80/7i77 thread, stock Debian Preemt-RT (3.2.xx) had terrible latency

[17:25:16] <skunkworks> so - jessie is going to get skipped for a rt-preeempt in the repositories?
[17:29:41] <mozmck> I believe there is one in the backport repository

[17:50:28] <jepler> this kernel is in jessie-backports
[17:50:38] <jepler> it doesn't get good RT performance on my laptop, but I don't know what does
[17:53:46] <jepler> looks like they're up to 4.1.6 now

[18:32:35] <archivist> oh dear, lacks linuxcnc threading experience :)
[18:33:10] <skunkworks> pcw had a conversation with him on cnczone. If he hasn't experienced it - it doesn't exist
[18:33:34] <archivist> an "expert"
[18:33:57] <cradek> back around the turn of the century, linuxcnc didn't have threading
[18:34:14] <cradek> in my extensive experience
[18:34:14] <skunkworks> wow - that reallys should be used more...
[18:34:23] <cradek> ok, I admit that was a very clumsy attempt
[18:34:47] <archivist> cradek, not even with a threadmill and rotary table ?
[18:35:15] <archivist> which is how I did my first threads and worms

[18:47:46] <skunkworks> I could use more points - it currently is using 6.
