#emc-devel | Logs for 2010-01-08

[01:14:14] <jepler> it turns out that calling up your ISP and sounding like you're clearly about to lose your composure is a good way to get them to actually fix the problem.
[02:06:03] <skunkworks> heh
[02:06:58] <cradek_> cradek_ is now known as cradek
[02:20:29] <jepler> I'd be happier if it was even less than .3% packet loss but I'll take that over the 55% it was earlier today
[02:59:57] <seb_kuzminsky> is anyone running emc2 on 64-bit successfully?
[03:08:04] <cradek> not that I've heard of
[03:12:13] <jepler> I am not anymore
[03:13:56] <jepler> the packages you get from running emc-install.sh on a 64-bit 8.04 system are the ones that I used at one time
[03:14:16] <seb_kuzminsky> how long did you run it? was it working well when you did?
[03:14:38] <jepler> I did control a real machine with it for a time. It ran the runtests OK. but after a few days it would always crash hard
[03:14:49] <jepler> not necessarily running emc
[03:15:16] <jepler> but I chalked it up to the hardware being dodgy (a few months later the motherboard died of "capacitor plague")
[03:15:25] <seb_kuzminsky> i see
[03:15:41] <jepler> it was a dual core machine, maybe the rtai turns out not to work on a single CPU? or maybe there really is something wrong..
[03:16:20] <seb_kuzminsky> or maybe the super-lame timings of kvm make it more likely to crash soon
[03:16:24] <seb_kuzminsky> who knows
[03:16:38] <seb_kuzminsky> is there a good non-emc2 rtai stress test?
[03:16:55] <seb_kuzminsky> i'm running the rtai "latency" test and it seems fine
[03:17:23] <seb_kuzminsky> hm, but the "preempt" test crashed it right away
[03:17:40] <seb_kuzminsky> it's pegged the CPU on the host, but i can still access the kvm debugger
[03:17:44] <jepler> unfortunately I don't even have a 64-bit 8.04 machine handy
[03:17:52] <seb_kuzminsky> want me to email you one? ;-)
[03:17:57] <jepler> no thanks
[03:18:49] <seb_kuzminsky> the linux kernel still responds to nmi
[03:19:50] <jepler> on the first reading I thought you said "nml"
[03:19:57] <seb_kuzminsky> heh
[03:20:22] <CIA-5> EMC: 03cradek 07tlo_all_axes * rccf5d7874a18 10/ (111 files in 42 dirs): Merge commit 'origin/master' into tlo_all_axes
[03:20:28] <jepler> hm, I have a vmware virtual machine named "ubuntu 64 bit" but its desktop is clearly not 8.04
[03:22:35] <seb_kuzminsky> rtai 3.6.1 (what we use on hardy) claims to support x86_64
[03:23:07] <jepler> yeah
[03:23:14] <jepler> it was a matching patch and all that good stuff
[03:25:02] <seb_kuzminsky> i've been meaning to reinstall my laptop, i think i'll make a separate partition to boot hardy-rtai on to test it on real hardware

[10:37:24] <CIA-5> EMC: 03micges 07joints_axes3 * rc0a6ece737b3 10/configs/scara/ (scara.ini scara_sim_4.hal): More cleanup of scara config
[10:39:05] <alex_joni> micges_work1: hi
[10:39:18] <micges_work1> hi
[10:40:52] <micges_work1> alex_joni: joints in scara can move -180->180 or -360->360?
[10:40:59] <alex_joni> my other project started working (the radio stuff), so soon I'll eb able to focus back to ja3
[10:41:04] <alex_joni> -360..360
[10:41:11] <alex_joni> hmm.. depends
[10:41:25] <alex_joni> on the machine, but generally I think more than -180..180
[10:41:37] <alex_joni> for joint0
[10:41:50] <alex_joni> joint1 can't move more than -180..180 as it will collide with the arm
[10:42:22] <micges_work1> I see it
[10:43:53] <micges_work1> and joint2?

[13:06:47] <jepler> weird. vmware's configuration wizard announces that 64-bit OSes won't run on my system (why?) but then it boots ubuntu-8.04.3-desktop-amd64.iso to the desktop just fine.
[13:53:03] <CIA-5> EMC: 03micges 07joints_axes3 * re2f5bff0bd81 10/src/emc/motion/ (control.c mot_priv.h motion.c): Fix position errors when switching teleop<->free mode
[14:33:42] <alex_joni> micges_work1: joint2 islinear
[14:33:48] <alex_joni> (crappy keyboard..)
[14:40:19] <cradek> micges_work1: I tested tlo_all_axes some last night. I ran into a bug that dgarr had already fixed in master, so I did the (somewhat difficult) merge
[14:40:51] <cradek> micges_work1: I didn't see any more obvious problems after that, but I didn't spend too much more time testing. I did not test a random config.
[14:42:12] <skunkworks_> micges sure is going to town.
[14:42:18] <cradek> yep
[14:42:57] <alex_joni> funky town?
[14:43:30] <skunkworks_> :)
[14:44:53] <micges_work1> cradek: ok I'll look at it later
[14:45:42] <alex_joni> jepler: what vmware version?
[14:46:21] <alex_joni> I installed the latest win version (2.something), and it doesn't have a user interface anymore :/
[14:46:29] <jepler> doh
[14:46:35] <jepler> I think I have an old vmware server 1.x
[14:46:48] <alex_joni> it installs an tomcat+apache server
[14:47:10] <jepler> huh
[14:47:15] <alex_joni> and you need a special browser for it to download a plugin for the interface
[14:47:23] <alex_joni> IE or Firefox
[14:47:42] <jepler> this machine has vmware because it used to run the cvs server vmware image
[14:48:03] <jepler> today I'd look at virtualbox-ose or qemu+kvm instead
[14:48:06] <micges_work1> alex_joni: scara works fine now
[14:48:30] <alex_joni> micges_work1: cool, I'll test it later
[14:48:49] <micges_work1> ok
[14:48:50] <alex_joni> jepler: it was convienient to just copy the old vmdk over
[14:50:56] <jepler> alex_joni: yep, exactly
[14:51:02] <jepler> good old-fashioned vendor lock in at its finest
[14:51:22] <cradek> I think qemu can read them
[14:51:40] <jepler> yeah, the internet will turn up suggestions for how to convert vmdk to other formats
[14:51:48] <alex_joni> I only needed a file out of it
[14:51:56] <jepler> then you're left with whether the guest has the right drivers to boot all the way to userspace
[14:52:01] <alex_joni> yapps based ;)
[14:52:51] <jepler> if you just need a file, it might be eaiser to get the image out of the vmdk and mount -o loop it
[14:53:17] <jepler> but, eh
[14:53:52] <alex_joni> jepler: tell that to Ray Ozzie
[21:27:11] <skunkworks_> http://groups.yahoo.com/group/mach1mach2cnc/message/116860
[21:46:05] <jepler> skunkworks_: something in particular you're calling to our attention?
[21:52:47] <skunkworks_> jepler: hmm - I just thought it was interesting info.
[21:53:08] <skunkworks_> A little bit of the method behind the madness.
