[00:01:49] <A2Sheds> FinboySlick: memleak has the fix, he'll be online a bit later
[00:03:18] <FinboySlick> A2Sheds: Really? I'd have expected this to be very uclubc specific.

[00:06:09] <memleak> FinboySlick, can you paste your pastebin again?
[00:06:11] <andypugh> That's probably one missing brace
[00:06:23] <memleak> I think I fixed this before.
[00:06:34] <FinboySlick> http://pastebin.com/C9mAfNUT
[00:07:14] <FinboySlick> memleak: You know, you're like a super-hero that only shows up at a certain time.
[00:08:16] <memleak> what gcc version are you using?
[00:08:25] <FinboySlick> 4.5.3
[00:08:53] <memleak> I take it you're using gentoo?
[00:09:18] <FinboySlick> portage might have given it away? ;) It makes cross-compiling a whole system very easy.
[00:09:36] <FinboySlick> And 4.5 has geode-specific optimizations.
[00:10:57] <memleak> i remember compiling RTAI back in September of 2010, and the kernel had to have inlining off and the -Os flag (optimize for size) had to be off in the kernel config
[00:11:04] <memleak> but this was back on .32.2
[00:12:05] <memleak> I never had to make any changes to mathcalls.h but maybe gentoo has too many distro specific changes
[00:12:37] <memleak> I only used arch and slackware in the past with RTAI from scratch and all
[00:13:23] <memleak> As for all these syntax errors... I'm not sure... I never had to touch any of the files you're having trouble on
[00:14:08] <FinboySlick> memleak: This is uclibc...
[00:14:14] <memleak> Ohh....
[00:14:22] <memleak> That is probably why.
[00:14:53] <memleak> EGLIBC might be a better bet if you want to keep things smaller
[00:15:24] -!- Loetmichel has quit [Ping timeout: 258 seconds]
[00:15:25] <memleak> uclibc isn't as compatable with GLIBC as EGLIBC, but changing the C library at this point will be a lot of work.
[00:16:22] <FinboySlick> memleak: Yes it will... I'd like to spend a bit more trying to hack through this before I pretty much start this system over from scratch.
[00:18:32] <memleak> errors in current RTAI-3.8 release make it impossible to use it with uclibc, but there is this thing called xenomai

[00:22:29] <FinboySlick> memleak: Some architecture background first then...
[00:22:57] <FinboySlick> EMC will want some sort of realtime kernel... But will it make a difference between xenomai and rtai?

[00:23:07] <memleak> oh...
[00:23:13] -!- mozmck [mozmck!~moses@client-] has joined #emc
[00:23:19] <memleak> no i forgot, emc only uses RTAI
[00:24:16] <andypugh> Actually, it can use another one.
[00:24:25] <memleak> seriously?
[00:25:03] <andypugh> Supposedly
[00:25:39] <andypugh> RTLinux and RTAI are supposedly supported by EMC2
[00:25:45] <memleak> as far as I know, uclibc doesnt support nearbyint() so... RTAI won't work with uclibc unless you want to write some uclibc patches
[00:26:31] <andypugh> A lot of the headers in rtapi.h are meant to make them look the same to the rest of the sytem
[00:27:12] <andypugh> There has also been some work looking at RT-preempt.
[00:27:22] <FinboySlick> memleak: you might be wrong on nearbyint() now.
[00:28:25] <memleak> it's been about a year since i looked at uclibc so maybe they patched it, maybe they didn't. i used to keep track of all the C library news, now i just want stuff working.
[00:29:13] <memleak> up until GLIBC 2.13 i lost track, because thats when I stopped messing with ARM kernels.
[00:32:48] <memleak> even if nearbyint() is supported, you would need more features i think.. i never had these problems with GLIBC / EGLIBC, but I've had about over 50 other issues, messing with EMC + RTAI on other distros
[00:34:24] <FinboySlick> memleak: According to someone in gentoo-embedded, I might just have some borked includes... There's lots of stuff missing that shouldn't be.
[00:34:40] <memleak> slackware, arch, and some of my own (a very long bash script i wrote which builds almost all of the stuff in the LFS handbook automatically)
[00:35:53] <memleak> as for your includes, try adding EXTRA_CFLAGS := -I/usr/include/
[00:38:40] <memleak> the guys in that room would probably know more about your issue than me
[00:53:36] <FinboySlick> memleak: I might have found the problem, keeping fingers crossed.
[00:59:26] <andypugh> <beats head on desk> 2 whole evenings, 2 whole evenings till 3am chasing a bug, worrying how far back it goes, wondering why commenting out all changes didn't make it go away. I just found that the bug was in my test code....
[00:59:42] <andypugh> ie, there was no bug.
[01:00:42] <Tom_itx> thoroughly tested though
[01:01:41] <FinboySlick> andypugh: Heh, reminds me wondering why STP wasn't working when I had disabled it on the specific ports I was testing.
[01:04:58] <andypugh> Well, at least one error message now says "......Or perhaps you forgot the "read" function?...
[01:05:03] <A2Sheds> andypugh: I did something similar a couple of years ago, I chased the bug for 2 weeks
[01:05:17] <andypugh> OK, that makes me feel better.
[01:05:45] <andypugh> It is the rewinding back through history and a sense of foreboding about just _when_ you broke EMC2

[01:10:54] <andypugh> Sorry, 360.
[01:11:22] <andypugh> That's a 7i64, 7i69, 7i70, 7i71 on a 5i23.
[01:12:14] <Tom_itx> sserial?
[01:12:18] <andypugh> Aye
[01:12:20] <Tom_itx> cool
[01:12:24] <Tom_itx> got it working huh?
[01:12:34] <andypugh> Not quite, but it is close.
[01:12:43] <Tom_itx> 5i23 or 5i25?
[01:13:10] <andypugh> I would have it working if I hadn't spent 2 nights chasing a comms-error bug that was really me fogetting to add the read thread.
[01:13:31] <andypugh> 5i23 at the moment, as it has more ports. The 5i25 is working too,
[01:14:25] <Tom_itx> is it part of the new set of boards they're just getting out?
[01:14:34] <andypugh> Yes

[02:01:26] <FinboySlick> memleak: You can tell it what to use as default cflags for building everything, yes. Typically if you don't care about your stuff being portable, you want -march=yourcpu or better -march=native, etc.
[02:02:13] <FinboySlick> memleak: For packages where some cflags are known to cause problems, maintainers override your choices.
[02:02:55] <FinboySlick> memleak: Did you fix cvs or something?
[02:03:35] <FinboySlick> I might be going a bit nuts but it seems the patch I used to fix the previous error is already applied when I pull in the source.
[02:03:36] <memleak> cvs... i never wrote a patch for cvs nor rtai, just asked some questions on the mailing list for rtai a long time ago
[02:04:33] <memleak> maybe you didn't hard reset your tree?
[02:04:42] <FinboySlick> memleak: I guess.
[02:04:57] <FinboySlick> memleak: Seen the latest error?
[02:05:19] <memleak> i rarly use cvs, but with git: git reset --hard
[02:05:45] <memleak> yes i have. i dont know how to fix it.
[02:05:59] <memleak> /bin/sh: line 1: 1396 Bus error
[02:06:48] <memleak> I never get bus errors with sh... :/
[02:06:57] <FinboySlick> memleak: It's a first for me too.
[02:07:20] <FinboySlick> I think it's the fixdep binary giving it though.
[02:07:42] <memleak> yeah i think so too from the looks of it, but what exactly is wrong im not sure
[02:07:58] <memleak> maybe if i saw the source...
[02:09:38] <memleak> if its line 1 maybe its something very obvious
[02:10:21] <FinboySlick> It's line1 of the script, but fixdep is a binary.
[02:11:41] <memleak> i have no idea... i've never seen anything like this, and i compiled quite a lot of things in my past

[03:38:58] <memleak> RTDM -> Real-Time Driver Model for RTAI
[03:39:00] <FinboySlick> memleak: I'm begining to wonder if I'm even building the right stuff.
[03:39:09] <memleak> https://www.rtai.org/documentation/fusion/html/api/rtdm_8h.html
[03:39:21] <memleak> I have no idea what exact step you are on
[03:39:50] <memleak> RTAI kernel -> RTAI userspace -> EMC
[03:40:39] <FinboySlick> memleak: userspace. But I'm not sure, if I should be building magma or plain rtai or if what I'm building matches what I patched my kernel with.
[03:40:57] <memleak> for magma just do make menuconfig
[03:41:14] <FinboySlick> memleak: I patched with this: hal-linux-
[03:41:19] <memleak> turn on math support and C99 support, and insert your number of CPU cores
[03:41:32] <FinboySlick> What userspace sources should I be looking for?
[03:41:45] <memleak> the cvs co magma thing
[03:43:08] <memleak> make menuconfig, then make, then sudo make install
[03:43:20] <memleak> or if you're doing it the gentoo portage way, its like that
[03:43:28] <FinboySlick> http://pastebin.com/3AWuewbJ is where it stops
[03:43:58] <FinboySlick> And honestly, looking at the source, I have no idea how that could compile, there's no trace of close_work being declared anywhere.
[03:44:50] <memleak> did you use ./configure or make menuconfig?
[03:44:58] <memleak> in your ebuild or whatever
[03:45:04] <FinboySlick> memleak: the ebuild did that, yes.
[03:45:12] <memleak> which one?
[03:45:32] <FinboySlick> I set my number of CPUs... The one from the emc howto, one moment.
[03:45:59] <FinboySlick> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl/emcinfo.pl?EmcOnGentoo
[03:46:04] <memleak> math funct support and C99 needs to be on to satisfy EMC
[03:46:37] <memleak> i never use ./configure...
[03:46:47] <memleak> do ebuilds support menuconfig?
[03:47:02] <FinboySlick> memleak: No, but there should be matching USE flags.
[03:47:20] <memleak> i seriously need to become a gentoo guru... it would be so much easier to manage my system with that.
[03:48:12] <FinboySlick> memleak: I'll be glad to give you a hand if you do so.
[03:48:55] <memleak> bad thing about migrating from slack to gentoo is losing the flexability to compile from source by hand, and the need to write scripts all the time
[03:50:02] <FinboySlick> memleak: Well, you don't loose that... You just run the same risk of borking your system if you do.
[03:50:12] -!- grommit has quit [Remote host closed the connection]
[03:50:13] <memleak> thats what i meant
[03:50:22] <FinboySlick> how does slack get around it?

[03:50:58] <memleak> slack just freezes the distro every year or so and never looks back, giving users the ability to just install a system and let the users customize the heck out of it
[03:51:02] <FinboySlick> (and ebuilds are very easy to make)
[03:51:37] <memleak> or you can just follow -current and have a quite new system automatically managed for the most part
[03:51:52] <FinboySlick> ebuilds will let you take advantage of sandbox, which will prevent whatever you build from overwriting something that another package installed (unless you force it)
[03:53:51] <FinboySlick> If you're just going for ./configure; make; make install... It won't be much harder for you to write an ebuild. If you modify the source, then do as you normally do, skip the make install part and generate a patch for your ebuild to apply.
[03:54:23] <FinboySlick> portage is already designed to pull stuff from git/csv/svn from an ebuild.
[03:55:27] <FinboySlick> memleak: out of curiosity, do you actually enable rtdm when you make menuconfig?
[03:55:35] <memleak> i use the defaults
[03:55:46] <memleak> i only turn on math support and c99 support and change # of cores
[03:55:48] <memleak> thats it.
[03:56:10] <FinboySlick> Maybe this ebuild is trying to enable all kinds of stuff that isn't in the default settings.
[03:56:19] <memleak> possibly.
[03:57:50] <memleak> btw i tried writing an ebuild for mesa (not the machine controlling stuff, but the mesa 3d graphics library, DRI etc) and it was a pain.. although i only had gentoo installed for about an hour before switching back. shoulda spent more time figuring it out
[03:58:23] <FinboySlick> memleak: The mesa ebuild didn't work for you?
[03:58:41] <memleak> well i wanted mesa from git master with very specific options turned on or off
[03:59:20] <FinboySlick> memleak: you just copy it to your local overlay, add/change the configure switches you want and tell it to grab from git.
[04:00:00] <memleak> :) you make it seem so easy.. anyway as for this RTAI ebuild.. it doesnt support menuconfig.. hmm..
[04:00:21] <memleak> ah! maybe run make menuconfig then remove the ./configure line in the ebuild and just have make do the rest!
[04:00:41] <memleak> messy yes. but how else can you go about it?
[04:00:42] -!- RyanS has quit [Ping timeout: 244 seconds]
[04:00:56] <FinboySlick> memleak: That wouldn't work. I'll make menuconfig on plain sources and see what goes in the .config file.
[04:01:07] <memleak> ok
[04:01:20] <memleak> be sure to run make clean to clean the directory
[04:01:59] <FinboySlick> memleak: I grabbed a fresh copy. Where are the options you set?
[04:02:26] <memleak> err... off the top of my head.. im not sure.
[04:02:57] <memleak> im in windows 7 right now playing deus ex human revolution, let me pop on linux to get the options for you if you like
[04:03:21] <FinboySlick> #cpus, mathfuns and C99?
[04:03:28] <memleak> yes
[04:03:32] <FinboySlick> Nothing else?
[04:03:38] <memleak> correct
[04:03:46] <memleak> works great for me
[04:04:26] <memleak> i dont touch anything else except those 3
[04:04:41] -!- Eartaker has quit [Read error: Connection reset by peer]
[04:04:45] <memleak> C99 support is an option that shows up after you enable math support

[04:06:15] <memleak> it should be right under it
[04:06:44] <FinboySlick> Yeah, found it all.
[04:06:51] <memleak> alright
[04:07:42] <memleak> i have tried "keep linux alinged to RTAI" or "keep RTAI top priority" or something too just to see, and i didnt notice any changes in latency
[04:08:05] <memleak> if you want, you can turn that on. it doesn't hurt from what i've seen.
[04:10:00] <FinboySlick> Hmmm, there's no direct translation between the ./configure script params and the menuconfig bits.
[04:10:18] <memleak> oh how convienent..
[04:10:49] <FinboySlick> When I have it figured out, I'll definitely be updating that ebuild.
[04:10:56] <FinboySlick> But for now, sadly, I must sleep.
[04:11:06] <memleak> alright really quick though
[04:11:12] <FinboySlick> Hmm?
[04:11:44] <memleak> you can view the "configure" file in a text editor and see if you can make more "translations" that don't show up in --help
[04:11:47] <memleak> just for future reference
[04:12:24] <FinboySlick> I'll just find the configure params that we do change and only mention those, see where that leads me.
[04:12:28] <memleak> or use grep and find similarities between Kconfig and configure
[04:13:24] <FinboySlick> If I want the latency test, I probably need to enable --enable-testsuite right?
[04:13:29] <memleak> no
[04:13:32] <memleak> leave that alone
[04:13:45] <memleak> latency test that you're looking for is latency-test from EMC
[04:13:53] <FinboySlick> Oh, good.
[04:14:04] <memleak> RTAI testsuite you leave alone.
[04:14:11] <FinboySlick> Ok, new attempt tomorrow. I was hoping to be running EMC today.
[04:14:33] <memleak> in an ebuild can you use cat?
[04:15:02] <FinboySlick> memleak: They're not really like shell scripts. What would you plan to do?
[04:15:04] <memleak> i.e. cat > .config << EOF then enter all your options in and then EOF at the end?
[04:15:19] <memleak> like run make menuconfig
[04:15:30] <memleak> then save the config to a specified file
[04:15:56] <FinboySlick> memleak: That's a very hack-y way of going about it. I'll use the ./configure bits first.
[04:15:59] <memleak> then in the ebuild, take all that stuff in the automated config with the few options changed and cat / output to file
[04:16:26] <memleak> most of my suggestions seem to be on the hacky side.... i need to watch that
[04:17:08] <FinboySlick> memleak: memleaks are meant to be flexible, they look at a system's use flags or in some cases, variables (like VIDEO_CARDS= for mesa) and do all the configuring for you prior to building. Same for patches.
[04:17:21] <FinboySlick> hehe, I mean ebuilds are flexible, not memleaks
[04:17:28] <memleak> hahaha!!!!!!
[04:18:39] <FinboySlick> http://www.gentoo.org/proj/en/devrel/handbook/handbook.xml?part=2&chap=1
[04:18:42] <memleak> memleak fixes are quite easy. valgrind, destroy / free, tada!
[04:19:29] <FinboySlick> memleak: what do you typically hack on besides EMC? You seem to me like an avid tweaker of things.
[04:20:49] <memleak> a lot of stuff.. video games, some kernels here and there, some ARM development, windows / registry hacks, distro building, general maintainence and performance fixes
[04:22:24] <FinboySlick> I'm not much of a coder but I always admired 'em. May I recruit you in my future army of devs dedicated to producing a real open-source CAD solution?
[04:22:55] <memleak> by video games i don't mean the playing, although i do that too. eeee.. i cant actually write a lot of code
[04:23:53] <FinboySlick> memleak: Good, we'll get you started on the rewriting OpenCASCADE, I expect a status update first thing tomorrow.
[04:24:17] <memleak> heh, i don't know enough of the languages to do such a thing
[04:24:47] <FinboySlick> memleak: Heh, to give you a hint, it takes longer to build than OpenOffice.
[04:25:26] <memleak> that actually says a lot....
[04:26:18] <memleak> probably do the entire GCC testsuite and make check on ppl...
[04:26:49] <FinboySlick> Heh. Anyway, goodnight for real this time.
[04:26:56] <memleak> good night!

[08:47:26] <Loetmichel> bjam67: the problem with usb is that the usb-specs state a maximum loop time for command/response of roughly 1 second.

[11:19:07] <IchGucksLive> hi all
[11:19:13] <IchGucksLive> JT-Shop:
[11:19:28] <IchGucksLive> at the shop ?
[11:20:18] <jthornton> still in the beer cave :)
[11:20:38] <IchGucksLive> or someone nows if i can maxe a fiktif Axis for instance its isier to generat a XYZ path
[11:20:57] <IchGucksLive> even if the mashine Hotwirer has no Z axis
[11:21:18] <IchGucksLive> so can i generad the Z axis in ini but no output in the hal
[11:22:00] <IchGucksLive> or im runnung into error if there is no pin connected
[11:25:16] <IchGucksLive> also it looks better in the Axis view B)
[11:26:06] <jthornton> I would have thought that a hotwire machine would have a YZ path
[11:26:20] <IchGucksLive> or another Question can i giv the G0 a other color as the G1 ?
[11:26:54] <jthornton> I'm sure you could hack axis.py and make it any color you want
[11:27:32] <IchGucksLive> the EDM post prozess gives me a XYZUV
[11:27:56] <jthornton> I thought you meant a foam cutting machine
[11:28:02] <IchGucksLive> wher z is the high from plane XY to UV
[11:28:40] <IchGucksLive> hacking Axis may be the way to do it
[11:29:22] <jthornton> oh I see the wire is vertical
[11:29:42] <IchGucksLive> horizontal with a 4,5m Span
[11:30:32] <jthornton> oh I don't have a clue now

[14:50:23] <cradek> I don't understand what kind of arc you mean, but I'm sure the answer is no anyway :-)
[14:51:09] <JT-Shop> ok, I kinda thought so
[14:51:59] <JT-Shop> what I meant was using the A as the Y but I guess it will have to be all G1 moves to make sense

[16:03:24] <ewidance> Hi all. I have configured many times EMC2 on various machine with success. This time, I 'hang'. It's a brand new motherboard ASUS P5G41T M-LX, with a dual core E 5700 Intel / 4Go ram / 250 Go SATA.
[16:04:32] <ewidance> Video is embedded (Chipset G41).
[16:04:47] <cradek> can you elaborate on "I 'hang'"?
[16:05:54] <ewidance> Sorry... I tried many things to try to have proper lantency tests, without success :
[16:07:37] <ewidance> Video driver = vesa, sound disactivated on mother board, frequency scaling disabled on bios, isolcpus=1 on boot
[16:08:10] <ewidance> I also tried to disactivate ACPI on bios, but it's worst.
[16:08:10] <A2Sheds> ewidance: out of curiosity.... what numbers are you getting for latency jitter?
[16:08:58] <ewidance> Symptoms : Jitter is 5000 / 7000, and suddently goes up to 1 000 000....
[16:09:31] <skunkworks> onboard video? Could you add a pcie or such video card to test?
[16:09:42] <ewidance> It don't seems to be regularly, not linked to a special event (network transfer, activity on video card, mouse, disks, etc..)
[16:10:28] <cradek> hmm
[16:10:47] <A2Sheds> http://wiki.linuxcnc.org/emcinfo.pl?TroubleShooting#Unexpected_realtime_delay_check_dmesg_for_details
[16:11:03] <ewidance> i've read the fine manual :)
[16:11:06] <A2Sheds> thats the first checklist
[16:12:18] <A2Sheds> try what skunkworks suggested, it has made a significant difference on several test boards
[16:13:30] <ewidance> I forgot : I've also enabled the SMI patch; This helped a lot. Same for disabling frequency scaling on BIOS; Unfortunately, i've no way to disable HT (but IS E5700 HT? I this it's a real dual core...)
[16:14:04] <ewidance> In short : i tried all in the TroubleShooting page...

[16:14:56] <A2Sheds> sometimes BIOS is still to blame
[16:16:05] <A2Sheds> just because there is an option in BIOS it doesn't mean it actually does anything or what it is suppose to do
[16:16:19] <A2Sheds> or the dev left options out
[16:17:06] <A2Sheds> and it gets worse when ACPI is turned off?
[16:17:53] <A2Sheds> ewidance: how often does it jump to 1,000,000?
[16:18:08] -!- IchGucksLive has quit [Ping timeout: 258 seconds]
[16:19:15] <A2Sheds> I had a VIA C7 + cn700 board that had 7-8K numbers and every ~90 min avg a jump to 300-600K
[16:24:31] <ewidance> A2Sheds: I just checked, there where a new BIOS 10/10/11... I'll try the update tonight. Yes it's words with ACPI off. I goest much more frequently to 1 000 000. In the actual config (SMI patch / vesa / sound disactivated / C1E support disactivated / Speed step disactivated), it happens sometimes 2 times in 5 minutes, and sometimes 1 time in 1/4 hour...
[16:27:32] <A2Sheds> ewidance: it's frustrating sometimes especially after you've purchased a new board that looked promising for EMC based on similar specs for boards with good numbers
[16:30:14] <ewidance> :) Yes.... Since it's a Jet under linux, and seems to be very promising with X accelerated drivers.... I really would like to make it works.... PS : i'm a system administrator, so i'm very comfortable with linux and... reading docs and manuals. But there i've no idea of what peripherial or functionnnality cause this...
[16:30:30] <A2Sheds> I have a core 2 duo + i945 that stays at 55,000, yet other boards with the same cpu+chipset are <5k
[16:32:14] <ewidance> I think i've read your report on that problems on mailing lists... Is there tools in RT linux to investigate on what cause this (except trying on bios...)?
[16:36:17] <ewidance> ?
[16:38:57] <A2Sheds> not in, but the ML here and https://mail.rtai.org/pipermail/rtai/ has discussions on lots of previous issues and fixes
[16:41:39] <A2Sheds> I have an older Athlon + SiS7x0 chipset that has 2-3K jitter numbers but PCIe or onboard video has issues
[16:43:42] <ewidance> Thank you for pointing those new tracks... I'll follow them and will come back to advice the results....

[20:19:46] <Jymmm> cradek: Are there commercial bits link that?
[20:20:00] <cradek> yes you can buy drills specially for sheet metal
[20:20:08] <Jymmm> cradek: Ah, thank you
[20:20:26] <Jymmm> I wasn't aware of such things existed is why I asked.
[20:21:09] <cradek> if you have a mill, a regular centercutting end mill might work fine too
[20:21:17] <cradek> don't try it in a drill press though
[20:22:08] <Jymmm> No mill, will see if I can pick up a small set of sheet metal bits.

[20:22:34] <andypugh> Step drills can work, too. (jumping in at the middle)
[20:22:47] <andypugh> What's the application?
[20:23:04] <cradek> if you have a bench grinder I bet you could make a suitable drill in a couple tries
[20:23:26] <cradek> I don't think the shape is too critical
[20:23:30] <Jymmm> cradek: I don't have any "spare" bits, so I'd have to buy some anyway.
[20:23:53] <cradek> ah
[20:24:39] <Jymmm> andypugh: I dont understand "aplication", It's a metal box that I won't be able to debur, so in essense a "blind hole" so to speak

[20:35:37] <andypugh> It looks an awful lot like a Ford to me. (though I don't doubt that it is a Datsun)

[20:36:54] <Danimal_garage> my saturn would be perfect, it even has electric power steering and a manual trans
[20:37:03] <Danimal_garage> plus plenty of battery room
[20:37:23] <Jymmm> Danimal_garage: Not smog exempt though.
[20:37:26] <cradek> I'm sorry I got rid of my 91 toyota mr2, which was manual steering/brakes/windows/transmission
[20:37:59] <cradek> might have had to sacrifice the trunk space though (all 2 ft3 of it)
[20:38:04] <Danimal_garage> Jymmm: it is if it's electric
[20:38:27] <Danimal_garage> cradek: the guy i'm machining parts for is building a 92 mr2 for a customer right now
[20:38:33] <Jymmm> Danimal_garage: I'm not sure how the ref's deal with experimental vehicles like that.
[20:38:37] <cradek> electric or regular restoration?
[20:38:38] <Danimal_garage> the part in my machine is going in it
[20:38:41] <Danimal_garage> electric
[20:38:44] <cradek> awesome
[20:38:59] <Danimal_garage> Jymmm: it's legal
[20:39:14] <cradek> it was my favorite car ever. I got rid of it because it was starting to smoke (needed an engine).

[20:39:26] <Jymmm> Danimal_garage: I'm sure it cna be, just not what you have to go through to get it legal

[22:01:06] <Jymmm> andypugh: It's all good =)
[22:02:19] <Jymmm> I wish there was modernized kits for things like charger circuits, uc (arduino covers that), motor controllers, etc
[22:03:16] <Jymmm> LED Drivers. Kits that take you from concepts to application in specific realms
[22:03:46] <DaViruz> like.. breadboard?
[22:04:44] <Jymmm> I hate breadboarding, but sorta. Like I want to learn about various chenmistry battery charging, PWM, when it's almost empty/full, and how you determine those things
[22:05:44] <Jymmm> best practices, etc.
[22:07:49] <Jymmm> Take steppers as example, You can wire two stepper motors together, turn one, and the other will turn too. It's a simple principal for us, but still kinda neat way to generate electricity, so include ways of harnessing that for whatever sorta type kit.
[22:08:46] <Jymmm> a 11yo kid would think that's kinda cool.
[22:09:52] <DaViruz> hell, even i think that's cool
[22:10:05] <Jymmm> me too actually
[22:10:17] <Jymmm> I HAD to try it too =)
[22:10:42] <Danimal_garage> how many people who are more or less linux and electrically illiterate build emc machines?
[22:11:52] <DaViruz> i know one, but he learned alot along the way
[22:12:52] <Jymmm> Well, I think it's more like 3 of 4... Meaning that they usually have 3 of the 4 things needed for CNC. Me I had the electronics, linux, electro-mechanical, but lack the maching background.
[22:13:13] <Danimal_garage> yea
[22:13:22] <Jymmm> Others have the maching, but lack the computer background.
[22:13:26] <Jymmm> etc

[22:18:15] <Tom_itx> Jymmm, you said CONNECT TO SERVER
[22:18:27] <Danimal_garage> no server needed
[22:18:29] <Jymmm> Tom_itx: Ok, then you DONT want to map a drive, you want to SHARE A FOLDER
[22:18:32] <Tom_itx> i can use windows share
[22:18:37] <Jymmm> Tom_itx: they are opposite things =)
[22:18:40] <Danimal_garage> right click on the folder in ubuntu and share it
[22:18:42] <Jymmm> Tom_itx: Yes,
[22:18:58] <Tom_itx> i'll figgr it out
[22:19:04] <Jymmm> Danimal_garage: you are confusing him
[22:19:09] <Tom_itx> no
[22:19:10] <Tom_itx> you are
[22:19:14] <Tom_itx> :)
[22:19:14] <Danimal_garage> ha
[22:19:23] <Tom_itx> i can figure it out
[22:19:25] <Jymmm> Danimal_garage: He wants to share a folder on windows, then grab the files and save them on ubuntu
[22:19:27] <Danimal_garage> i just did it, i know how it works lol
[22:19:36] <Danimal_garage> other way around
[22:19:38] <Tom_itx> i just felt like confusing the channel a while
[22:19:55] <Jymmm> Danimal_garage: No, not the other way around
[22:20:00] <Tom_itx> see what answers i could get
[22:20:25] <Jymmm> Danimal_garage: He wants to draw in windows, then pull into ubuntu
[22:20:32] <Tom_itx> it says i need to install windows sharing service first
[22:21:01] <Danimal_garage> Jymmm: it depends on which computer he's doing it rom
[22:21:03] <Jymmm> Tom_itx: Is this an OEM XP ?
[22:21:09] <Tom_itx> no
[22:21:18] <Danimal_garage> i put the files from windows into the ubuntu folders from the windows machine
[22:21:27] <Jymmm> Tom_itx: Install the service, but you might need the original install CD
[22:21:32] <Tom_itx> Danimal_garage, that's what i wanna do
[22:21:43] <Tom_itx> Jymmm, not in ubuntu
[22:21:46] <Tom_itx> :)
[22:22:01] <Danimal_garage> after i write the g code i just save it in the cnc machine from my windows box
[22:22:08] <Jymmm> Tom_itx: SMB is built into ubuntu
[22:22:16] <Danimal_garage> for that, just share the folder in ubuntu where the files go
[22:22:18] <Tom_itx> then why did it ask?
[22:22:21] <Jymmm> and installed by default unless really old version
[22:22:35] <Jymmm> Tom_itx: what version?
[22:22:41] <Tom_itx> live cd
[22:22:51] <Tom_itx> 1004
[22:22:52] <Danimal_garage> if it's not professional, it doesnt have the network goodies
[22:22:56] <Jymmm> lol, that doens't count.
[22:23:08] <Jymmm> Tom_itx: It's a liveCD, many features aren't loaded
[22:23:14] <Tom_itx> dan, my xp is pro
[22:23:20] <Tom_itx> and i have several original cd's
[22:23:36] <Tom_itx> Jymmm, it's an install from the live cd
[22:23:41] <Tom_itx> ver 10.04
[22:24:01] <Jymmm> Tom_itx: You said live, so isit installed to the hdd already?
[22:24:06] <Danimal_garage> i think you need to set up a workgroup or homegroup on the xp machine
[22:24:25] <Tom_itx> i could have it done already if you'd quit buggin me... sheesh!
[22:24:26] <Jymmm> Danimal_garage: he shoulded need to, unless the install was funky.

[22:38:35] <cradek> yeah joomla is swiss cheese and alex is going to fix or at least improve it this weekend I think.
[22:38:54] <cradek> (not really my area of expertise...)
[22:40:59] <FinboySlick> I only said it because I keep fixing the doodoo the web devs get themselves into at work using it ;)
[22:41:13] <Tom_itx> ok Jymmm, how do i change permission once the files are copied over so i can edit them in ubuntu?
[22:41:18] <FinboySlick> I'm sure that competently setup, it's alright.
[22:41:41] <FinboySlick> Tom_itx: What are you setting up?
[22:41:48] <Jymmm> Tom_itx: From within the folder the files are ain... sudo chmod 777 *
[22:41:57] <Jymmm> s/ain/in/
[22:42:00] <FinboySlick> Jymmm: You mad?
[22:42:06] <Tom_itx> i just wanna make an ubuntu directory available so i can copy my cnc files over from windows
[22:42:08] <Jymmm> FinboySlick: Hell no.
[22:42:27] <Tom_itx> i did that but now the permissions are readonly on the files and
[22:42:31] <Tom_itx> - and
[22:42:32] <FinboySlick> Very very few cases where 777 should be on a file.
[22:42:50] <Jymmm> Tom_itx: Ok, make the folder the same perms too
[22:42:54] <Tom_itx> but i want this automatic so i can just copy the files and not worry about it
[22:43:24] <FinboySlick> Tom_itx: Does your user own the files on the ubuntu box?
[22:43:32] <Jymmm> FinboySlick: He needs the execute bit or he won't be able to see them in a directory listing.
[22:44:10] <Jymmm> Tom_itx: cd ../; sudo chmod 777 <shared_folder_name_goes_here>
[22:44:16] <Tom_itx> they're listed with a lock by them
[22:44:31] <FinboySlick> Wait, is this joomla or samba or what?
[22:44:51] <Jymmm> FinboySlick: ubuntu file browser
[22:45:23] <FinboySlick> You're saying that nautilus doesn't show files which aren't executable?

[22:45:50] <Jymmm> FinboySlick: for file LISTINGS, it's weird I know
[22:46:20] <Jymmm> FinboySlick: You can't browse a smb folder unless the folder has x bit set
[22:47:01] <Tom_itx> it says nobody owns the files
[22:47:17] <Jymmm> Tom_itx: that sounds about right
[22:47:30] <Jymmm> Tom_itx: user 'nobody'
[22:47:43] <Tom_itx> it also says since i'm not nobody i can't change the permissions
[22:47:57] <Jymmm> did you use sudo ?
[22:48:22] <FinboySlick> Tom_itx: Could you describe the setup to me a bit more clearly? You're on windows trying to edit files that are on your ubuntu box? Or you're on ubuntu trying to edit files that are on your windows box?
[22:48:48] <Jymmm> FinboySlick: that's the $64,000 question
[22:49:11] <FinboySlick> Jymmm: I suggest you figure it out before you mislead him :P
[22:49:22] <Tom_itx> i changed the folder to read/write with exe access and applied that to the folder and files in it
[22:49:22] <Tom_itx> but it didn't affect it
[22:49:22] <Tom_itx> via the gui not chmod
[22:49:52] <Tom_itx> i copied the files from windows to ubuntu to a shared folder
[22:49:54] <FinboySlick> Okay, so he's on ubuntu... I assume accessing a windows share.
[22:49:55] <Jymmm> Tom_itx: do it all from shell, not gui
[22:50:08] <Tom_itx> i am unable to edit them in ubuntu
[22:50:18] <Jymmm> Tom_itx: ya lazy bastard!
[22:50:21] <FinboySlick> Tom_itx: Is the folder shared by your ubuntu box?

[22:55:16] <FinboySlick> Jymmm: I'm pretty sure you're wrong on the execute bit, btw.
[22:55:36] <FinboySlick> At least for files.
[22:56:51] <cradek> you need the x bit on directories to enter them. you don't need or want the x bit on files, but if you're serving windows machines they're oblivious anyway.

[23:01:16] <Tom_itx> i may need to set up a network share
[23:02:03] <FinboySlick> Tom_itx: I think so too. With samba, you might want to look into 'force user' if you're not going to be authenticating as a known user on the linux box.
[23:03:02] <Tom_itx> i set the share up as guest and was able to copy the files but not able to edit them once copied
[23:03:05] <FinboySlick> Tom_itx: If you want convenience and the username on your windows and linux box match, just make sure smbpasswd matches your windows password and it won't even bother you for one.
[23:03:28] <FinboySlick> Tom_itx: That's likely because they didn't belong to the user you tried to edit them as.
[23:04:01] <Tom_itx> and it won't let me log in as the user i am on ubuntu
[23:04:37] <FinboySlick> Tom_itx: You need smbpasswd to set a samba password. Ubuntu might have some sort of gui for such things but I don' t know it.
[23:04:58] <Tom_itx> it's ok, at least i know what the problem is
[23:05:10] <Tom_itx> i got other stuff to worry with first
[23:05:16] <FinboySlick> OK.
[23:05:37] <Tom_itx> i was just sitting here with both machines and figured i'd try it
[23:05:42] <FinboySlick> Tom_itx: You on an install from the livecd? I need to setup something similar so I might pave the way.
[23:05:53] <Tom_itx> yes
[23:06:17] <FinboySlick> Okay, food first though.
[23:06:34] <Tom_itx> it's just a network permission thing i'm sure
[23:07:52] <Tom_itx> funny, it won't let me edit it but it will let me move it to the trash and delete it

[23:12:11] <Tom_itx> it's just as easy to share the windows folder and access it thru ubuntu
[23:12:31] <FinboySlick> Don't share the folder as guest.
[23:12:39] <Tom_itx> yes
[23:12:50] <FinboySlick> Just share and don't allow other users to write.
[23:13:06] <FinboySlick> When you try to access it from windows, it'll ask for a user/password
[23:13:09] <FinboySlick> Feed it that.

[23:14:42] <Tom_itx> and i entered it in the windows login

[23:19:58] <FinboySlick> Tom_itx: The main issue being that it doesn't accept your password unless you share as guest, right?
[23:20:15] <FinboySlick> (I checked and files are editable by default too, no premission business to mess with).
