[00:53:09] <KGB-linuxcnc> 03andy 05master 0a2f75e 06linuxcnc 10src/emc/ 10rs274ngc/interp_cycles.cc 10rs274ngc/rs274ngc_interp.hh * Make the behaviour of G85 more as-expected
[00:53:22] <jepler> so on BBB with the "machinekit" image, glxinfo says: OpenGL renderer string: Software Rasterizer
[00:53:38] <jepler> so it's rasterizing axis's plot on the slow cpu and then shipping bitmaps over the network
[00:54:20] <andypugh> That sounds suboptimal
[00:59:04] <jepler> I believe it is
[01:04:32] <jepler> this makes it use the glx wire protocol instead: sudo chmod 000 /usr/lib/arm-linux-gnueabihf/dri/swrast_dri.so
[01:04:36] <jepler> it's somewhat better performing
[01:04:49] <jepler> (still other than great, however)
[01:06:27] <jepler> next thing it would be nice to understand is why milltask takes 20%CPU when it's idle
[01:07:18] ChuangTzu is now known as JohnSmith
[01:07:29] <andypugh> Maybe it checks to see if it is really idle more assidiously than necessary?

[01:13:44] -!- andypugh has quit [Quit: andypugh]
[01:14:15] <jepler> changing the task timeout to 10ms instead of 1ms knocks milltask way down
[01:14:45] <jepler> ssh encryption takes 30% CPU

[01:28:02] -!- zzolo has quit [Quit: zzolo]
[01:30:12] <jepler> and changing the hardcoded time for backplot polling seems to help too

[17:29:24] <seb_kuzminsky> ok folks, i think i'm ready to switch to docs on www.linuxcnc.org over to the ones that the buildbot makes
[17:30:26] <cradek> yay
[17:30:55] <seb_kuzminsky> basically i want to make it so that when you go to http://www.linuxcnc.org/docs/, it looks like http://www.linuxcnc.org/stage-docs/ instead
[17:31:06] <seb_kuzminsky> all the 'older versions' should be identical
[17:31:21] <seb_kuzminsky> the 2.5 and devel should contain the latest new docs from the buildbot
[17:32:18] -!- wboykinm has quit [Remote host closed the connection]
[17:32:28] <seb_kuzminsky> i fixed some minor broken links & markup problems with the top two levels of index.html files (which are *not* made from sources in our git)
[17:33:13] <skunkworks> Yay!
[17:35:40] <seb_kuzminsky> i also fixed the links (in 2.5 and master) to the HAL manual, they used to point to the old name for the document (from may 2013), they now point to the new name for the document
[17:35:50] <seb_kuzminsky> and i added our logo to the docs front page ;-)
[17:36:01] <seb_kuzminsky> i spot checked and didnt see any problems
[17:36:23] <seb_kuzminsky> i ran the w3c linkchecker and found too many problems to fix right away, but they're all in our old docs too i think :-/
[17:37:23] -!- wboykinm has quit [Ping timeout: 260 seconds]
[17:37:31] <seb_kuzminsky> http://highlab.com/~seb/linuxcnc/checklink-docs/
[17:38:01] <seb_kuzminsky> i guess i'll announce this on emc-developers and cut over in a day or two if there's no complaints
[17:40:38] <cradek> hm, lots of broken links to external sites
[17:40:52] <cradek> I didn't realize we had those in the docs
[17:41:01] <cradek> thanks for doing this work - it'll sure be nice.
[17:42:07] <seb_kuzminsky> also some internal fragment anchors missing
[17:42:28] <cradek> my spot check (probably with less coverage than yours) also came out fine
[17:43:03] <seb_kuzminsky> maybe i should just do the switch-over and announce it on emc-users and ask people to point out problems, rather than doing that other thing i said

[19:42:31] <seb_kuzminsky> i dont know how to joomla
[19:44:15] <seb_kuzminsky> i guess i could just change the $HOME/docs symlink, but i dont know what the effects would be

[20:30:37] <andypugh> Hi
[20:30:45] <andypugh> Just about to edit the docs
[20:39:38] <linuxcnc-build> Hey! build docs #1118 is complete: Warnings [8warnings compile]
[20:39:38] <linuxcnc-build> Build details are at http://buildbot.linuxcnc.org/buildbot/builders/docs/builds/1118
[20:47:26] <andypugh> This feels like a stupid question, but if I edit the asciisoc, where do I look to see what the effect was?

[21:20:30] <seb_kuzminsky> andypugh: two ways
[21:20:48] <seb_kuzminsky> you can run 'make docs' and look at the html & pdf outputs
[21:21:28] <andypugh> That was the part I was missing, I guess. I have never worried about whether the docs were being built or not.
[21:21:38] <seb_kuzminsky> or you can push to the buildbot and look in http://buildbot.linuxcnc.org/doc/
[21:22:29] <seb_kuzminsky> oh wait no, i just turned that off, it's on www.linuxcnc.org now, but it's in /stage-docs instead of /docs
[21:22:43] <seb_kuzminsky> due to my inability to figure out the webserver config :-/
[21:25:51] <andypugh> I am building it locally first for the practice
[21:26:36] <seb_kuzminsky> make sure you have all the build-deps installed, the docs need some things that the code doesnt
[21:27:05] <seb_kuzminsky> cd debian; ./configure -a || ./configure sim; cd ..; dpkg-checkbuilddeps
[21:31:03] <andypugh> It looks promising so far
[21:31:39] <seb_kuzminsky> cradek pointed out that one great thing about asciidoc is that the patches are totally human-readable
[21:34:37] <seb_kuzminsky> los colorados
