[02:02:41] <KimK> Any git gurus here tonight? I have three unrelated git repos (~/foo ~/bar ~/baz) and I thought I'd try to setup gitweb locally to browse them. But gitweb setup is asking about git projectroot and <projectname>.git. Should I have set them up to look more like ~/gitprojects/foo.git ~/gitprojects/bar.git ~/gitprojects/baz.git ? I have gitweb running up to "no projects found".
[02:04:02] <KimK> I guess I could set gitprojectroot just to "/", is that kosher?

[04:26:28] <cradek> KimK: gitweb sucks compared to gitk, and gitk requires no setup
[04:26:51] <cradek> KimK: so this guru's advice is to stop hitting yourself with that particular stick
[04:42:46] <KimK> cradek: Ha, OK. But I'm learning so much about the stick, I mean about git

[05:51:18] <KimK> OK, finally got gitweb running. I did not know about the importance of /var/cache/git, so a little tinkering and three symbolic links and I'm in business. And thanks for the advice just the same, I appreciate it very much.

[14:04:02] <skunkworks> so - it sounds like Yi-Shin Li is just communicationing over usb similar to the printer port communication? (it isn't actually doing motion in the mesa card)
[14:04:34] <skunkworks> I guess I could ask
[14:05:40] <skunkworks> it would be interesting to see the s-curve 'patch' if emc is still emc
[14:09:48] <SWPadnos> the thing about USB is that we expect the feedback lag to be too long, making threading or other feedback-dependent operations not work
[14:10:15] <skunkworks> right
[14:10:17] <SWPadnos> the other thing, which it's cool that they may have solved, is that we can't use Linux device drivers in HAL
[14:10:33] <skunkworks> ooooh
[14:10:56] <SWPadnos> so either they made an RTAI USB driver, they made it possible to use Linux device drivers, or they're pumping out loads of data in userspace (non ooooh)
[14:11:00] <skunkworks> but you agree that is is probably just using the mesa card like it is used with the printer port?
[14:11:05] <SWPadnos> no idea
[14:11:22] <skunkworks> heh
[14:11:29] <SWPadnos> he said they're accessing the registers of the Mesa FPGA via a wishbone<->USB "tunnel"
[14:12:06] -!- mk0 has quit [Quit: Leaving]
[14:12:07] <SWPadnos> (wishbone is an open bus specification used in FPGAs, for communication between soft processors and peripherals, among other things)
[14:12:34] <skunkworks> ah
[14:13:02] <SWPadnos> bbiab
[14:36:42] <jepler> videos are a fun teaser, but the money shot is when you share your code
[14:36:54] <cradek> there are git urls
[14:37:11] <jepler> oh
[14:37:26] <jepler> I haven't read the thread, but I assumed from what skunkworks and SWPadnos were saying that there was no code available
[14:38:04] <archivist> he added later to the thread
[14:39:07] -!- JT-Work [[email protected]] has joined #emc-devel
[14:42:04] <skunkworks> oh - his whole emc repository. Neat.
[14:42:16] <skunkworks> cradek: have you peeked yet?
[14:42:38] <jepler> There appear to be 2 authors. The work is based on the ja3 branch. There are 447 commits, 791 files changed, 73764 insertions(+), 101203 deletions(-)
[14:43:06] <jepler> er, check that, I got the wrong diffstate
[14:43:11] <jepler> 125 files changed, 28032 insertions(+), 3131 deletions(-)
[14:43:18] <cradek> lots of interesting stuff
[14:43:40] <jepler> .. including "eTouchy"
[14:43:59] <skunkworks> etouchy?
[14:44:04] <jepler> btfoom
[14:45:26] <jepler> looks like it's touchy with GUI controls added everywhere chris's wisdom indicated there should be physical controls
[14:45:47] <jepler> maybe I'm mistaken, let me look a bit closer
[14:45:48] <skunkworks> ah - eww
[14:47:40] <jepler> some changes regarding joint mode support. lots of spurious whitespace changes. and, yes, GUI elements for operations that should be done with a physical jogwheel.
[14:49:08] <cradek> hal/components/wou_stepgen.c:138:17: error: wou.h: No such file or directory
[14:49:21] <cradek> at least one missing file is keeping me from building it
[14:51:45] <jepler> there are lots of fprintfs in that file, so it's clearly not running in rtai
[14:51:50] -!- emcrules_ has quit [Read error: Connection reset by peer]
[14:52:35] <psha> cradek: wou is in libwou
[14:52:45] <psha> in on github under same user
[14:52:49] <cradek> oh ok
[14:53:10] <psha> it's userspace comp based on libftdi
[14:53:50] <cradek> I'm interested in the jerk limiting - not sure how much work it would be to separate it - I wonder if they're interested in contributing it.
[14:59:58] <psha> jepler: what's left for docs? Submakefile integration?
[15:00:50] -!- e-jones [e-jones!~jkastner@nat/redhat/x-vvatatnesuqvnwcv] has joined #emc-devel
[15:10:18] <skunkworks> well - maybe it can be used as a starting point
[15:26:02] <psha> http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/robots.txt
[15:26:25] <psha> that's intriguingly
[15:26:27] <psha> :)
[15:26:57] <psha> it reads as 'go and read that log! there was something interesting!' :)
[15:31:19] <skunkworks> that was actually for me.
[15:31:57] <skunkworks> I had inadvertantly pasted some info that should not have been public. It was until the log could be edited.
[15:32:34] <cradek> haha, good times
[15:32:54] <skunkworks> shit happens ;)

[15:36:05] <psha> s/no/now/
[15:43:05] <skunkworks> psha: how is the conversion coming
[15:54:08] <psha> docs?
[15:54:14] <psha> waiting for jeff's approval :)
[15:54:26] <psha> only left part is Submakefile integration i think
[15:59:03] <skunkworks> nice work

[16:26:43] <IchGuckLive> hi all , i got a somthing,My Students asked, woudent it be better in the documentation if there where some symbolic picture of the G words like G83 ZQR wahat is what like it is in the pal documentation ?

[16:30:32] <cradek> I agree pictures for the canned cycles would be great
[16:31:29] <IchGuckLive> the documentation is not open as the wiki so we can easy implement that or ?
[16:32:39] <seb_kuzminsky> the documentation is totally open for you to edit
[16:32:39] <cradek> the documentation is currently being translated to a new format, so it would be best to wait a few days/weeks before doing major work on it. but after that, git patches are the best way to submit improvements, just like for the source code
[16:33:33] <IchGuckLive> agree

[23:50:53] <alex_joni> hmm
[23:51:06] <alex_joni> maybe there's a separate make process beeing spawned?
