[00:00:10] <BigJohnT> the ">" is to direct the output?
[00:00:32] <eric_U> yes or it shows up on screen
[00:01:35] <BigJohnT> how do you pick the font?
[00:02:43] <eric_U> my question too
[00:03:14] <eric_U> truetype-tracer [-?] [-u] [-f /some/file.ttf] 'The Text'
[00:03:30] <eric_U> next question?
[00:04:12] <BigJohnT> what do I have to do to make a python GUI for this?
[00:04:20] <eric_U> (font: /usr/share/fonts/truetype/ttf-bitstream-vera/VeraBI.ttf)
[00:04:31] <eric_U> learn how to make python guis
[00:05:51] <BigJohnT> I know how to make python GUI's I wrote the G-Code generators on wiki...
[00:06:00] <eric_U> if you use tamil fonts, you're in luck
[00:06:09] <BigJohnT> how do I "call" the executable?
[00:06:21] <BigJohnT> from python?
[00:06:22] <eric_U> is there a method to make a system call?
[00:06:36] <BigJohnT> hmm, let me look
[00:08:49] <BigJohnT> looks like getoutput(cmd) might do it...
[00:09:25] <BigJohnT> but wait there is more...
[00:10:05] <BigJohnT> yes I can use os.system(cmd)....
[00:14:31] <BigJohnT> ok that works...
[00:19:18] <BigJohnT> hmmm, wonder how I can specify the location to start instead of 0,0?
[00:19:59] <eric_U> modify the output
[00:20:30] <eric_U> what does -u do?
[00:20:37] <BigJohnT> I could do that...
[00:20:55] <BigJohnT> unicode
[00:21:00] <eric_U> ah
[00:22:08] <eric_U> or you could modify the program to use a 5th parameter
[00:22:39] <eric_U> might be nice to be able to input all parameters on command line :)
[00:22:56] <BigJohnT> yes but it's most likely in C and I'm not real good at C
[00:25:02] <BigJohnT> I can use the -dxf option and open it in QCad and move it around where I want but I still have to generate the g code...
[00:25:57] <BigJohnT> It would be nice to input all the info into a GUI and hit go!
[00:27:08] <BigJohnT> I see you can specify the safe height, depth of cut, scale, feed in the ngc file...
[00:35:48] <eric_U> yeah, needs a command line option for all those parameters
[00:36:03] <eric_U> I don't know gcode, how would you make an offset?
[00:36:26] <toastydeath> an offset to what
[00:36:43] <toastydeath> oops nevermind bye
[00:36:49] <SkinnYPuppY> doh
[00:36:56] <BigJohnT> an offset in EMC?
[00:36:56] <alex_joni> an offset is easiest
[00:37:02] <eric_U> ok, that was more random than usual
[00:37:15] <alex_joni> just move to desired location (where you want 0,0 to be) and hit touch-off in axis
[00:37:19] <BigJohnT> and yes it's in C...
[00:37:38] <alex_joni> BigJohnT: although all locations are actually scaled in the output code
[00:37:41] <eric_U> BigJohnT wants some kinda offset for the file made by the truetype tracer program
[00:37:49] <alex_joni> eric_U: I figured
[00:37:55] <eric_U> but he seems to have forgotten that
[00:38:04] <BigJohnT> I did?
[00:38:08] <eric_U> seemingly
[00:38:31] <BigJohnT> or a start point but as alex said it can be done in EMC
[00:38:39] <alex_joni> 02:16 < BigJohnT> hmmm, wonder how I can specify the location to start instead
[00:38:39] <alex_joni> of 0,0?
[00:39:04] <alex_joni> the only downside is if you want to do more than one text at once
[00:39:13] <alex_joni> but a startpoint won't help much either
[00:39:16] <eric_U> that's what I was thinking
[00:39:28] <alex_joni> you'd want paragraphing and alignments & all next, won't you
[00:39:34] <BigJohnT> for ttt my thoughts to have some way to specifiy the start point and scale mayby...
[00:39:43] <alex_joni> BigJohnT: scale is easy
[00:39:44] <eric_U> I was thinking I wanted rotation :)
[00:39:48] <BigJohnT> now that you mention it
[00:39:54] <alex_joni> it's a field in the output file
[00:39:58] <eric_U> in 3 dimensions
[00:40:03] <BigJohnT> what about fit to curve too
[00:40:04] <alex_joni> you'd also want cutting speed
[00:40:09] <alex_joni> and safe height
[00:40:20] <BigJohnT> those are in the ngc file...
[00:40:20] <alex_joni> fit to probed surface
[00:40:21] <eric_U> fit to curve would be nice
[00:40:30] <eric_U> right, fit to surface
[00:40:42] <eric_U> in 5 axis mode
[00:40:45] <alex_joni> insert mug, probe surface, engrave with name
[00:40:48] <SkinnYPuppY> Pocket island option ;o)
[00:40:51] <BigJohnT> all you need is bob crap for that
[00:41:25] <alex_joni> hmm.. think I'll try a fit to surface myself
[00:41:38] <archivist> Im finding touchoff a pain in the a
[00:41:39] <alex_joni> bed defines a rather inviting flat surface
[00:41:44] <alex_joni> archivist: how so?
[00:41:45] <eric_U> I ain't spendin' no $1000 for something that alex_joni offered to write for free
[00:42:16] <alex_joni> don't forget that 1000$ donation you wanted to send me so gratefully
[00:42:24] <archivist> alex_joni, I need to write it up/define what my needs are
[00:42:25] <BigJohnT> you can get bob cad for $300 and give the $700 left over to alex
[00:42:33] <eric_U> my wife would kill me: "didn't alex_joni offer to write that for free? you idiot"
[00:43:01] <archivist> alex_joni, but its the slow part of setting up now
[00:44:17] <alex_joni> I somehow feel I'll be ending up empty afterall
[00:44:45] <BigJohnT> just think of the fun you will have alex
[00:45:17] <archivist> I need to probe dia of gear blane and the width of the cutter(on a curve) so get the best position
[00:45:23] <BigJohnT> you can teach me C so I can modify the program...
[00:45:25] <archivist> blank
[00:45:53] <alex_joni> BigJohnT: void main(void) {}
[00:46:01] <BigJohnT> LOL
[00:46:15] <alex_joni> that's your first program & lesson
[00:46:18] <alex_joni> (comes free too)
[00:46:19] <archivist> K&R 2ed
[00:46:31] <BigJohnT> at least put "hello world" in the program
[00:46:57] <alex_joni> C or C++ ?
[00:47:09] <BigJohnT> what is it printf "hello world"
[00:47:17] <BigJohnT> C++
[00:47:21] <BigJohnT> why not
[00:47:22] <archivist> printf("%s","hello world\n");
[00:47:32] <alex_joni> c++: cout << "hello world\n";
[00:47:33] <archivist> iirc
[00:47:39] <BigJohnT> hey I remembered the printf part
[00:47:41] <SWPLinux> right
[00:47:43] <alex_joni> c: printf("hello world\n");
[00:47:54] <alex_joni> archivist: yours is fprintf
[00:47:57] <archivist> wot no format
[00:47:59] <alex_joni> or sprintf
[00:48:22] <alex_joni> archivist: you can printf("hello world #%d\n", world_num);
[00:49:37] <SWPLinux> printf("Hello %s\n", "world")
[00:49:59] <BigJohnT> ttt.c must be in C it uses printf
[00:50:16] <alex_joni> char w[6]="world\0"; printf("hello %s\n", w);
[00:50:27] <alex_joni> BigJohnT: C++ may use printf
[00:50:34] <BigJohnT> ok
[00:50:52] <BigJohnT> but doesn't have to ?
[00:50:56] <alex_joni> yup
[00:51:01] <BigJohnT> ok
[00:51:33] <BigJohnT> it's all coming back to me and it makes my head hurt...
[00:51:40] <archivist> so many ways with C
[00:52:56] <BigJohnT> ttt.c is only 326 lines...
[00:53:51] <BigJohnT> if you don't tell it what to print it does "Hello World"
[00:54:16] <alex_joni> see.. now you definately should know how to change it
[00:54:32] <BigJohnT> thanks for the C refresher course...
[00:54:40] <BigJohnT> I can break it for sure LOL
[00:55:24] <BigJohnT> good fodder for the brain to relearn C I think
[00:56:04] <BigJohnT> * BigJohnT is going upstairs
[00:56:06] <BigJohnT> thanks
[00:56:44] <BigJohnT> goodnight alex
[00:56:51] <alex_joni> good night
[00:57:12] <eric_U> did he finish the code? no sleep til then
[00:58:53] <alex_joni> can you guys check out www.linuxcnc.org ?
[00:59:08] <alex_joni> I just did some updating.. hopefully you can't find anything borken
[00:59:32] <eric_U> you broke search
[00:59:40] <jlmjvm> alex_joni:im going to put the encoders back on my mill sometime in the next few days,will any of stuff from the 2.1.7 setup be applicable?
[01:00:01] <alex_joni> eric_U: how do you mean?
[01:00:06] <eric_U> kidding
[01:00:20] <eric_U> just the first thing I could think of
[01:00:21] <alex_joni> * alex_joni silently brings out the cattle prod
[01:04:41] <eric_U> jlmjvm, they changed some names
[01:04:51] <eric_U> I don't think the logic would have changed
[01:05:26] <alex_joni> eric_U: right
[01:11:07] <jlmjvm> before changes were made to the hal file and the core stepper also,but the new doesnt have the core stepper any more
[01:11:20] <alex_joni> jlmjvm: it sure does ;)
[01:11:30] <jlmjvm> im running a stepconf setup
[01:11:37] <alex_joni> ah, then it doesn't
[01:11:44] <jlmjvm> k
[01:11:51] <alex_joni> but I bet the stepconf might not be sufficient for your type of setup
[01:12:02] <alex_joni> you're in less trouble using the old config
[01:12:12] <alex_joni> or rather a copy of it ;)
[01:12:18] <jlmjvm> i still have the old configs
[01:12:39] <alex_joni> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?UPDATING#Changes_between_2_1_x_and_2_2_x
[01:12:43] <alex_joni> * alex_joni goes to bed
[01:12:47] <alex_joni> good night all :)
[01:39:39] <Guest546> tap tap
[01:39:43] <Guest546> is this thing on?
[01:40:27] <alex_joni> alex_joni has kicked Guest546 from #emc
[01:41:25] <Guest274> grr
[01:41:27] <Guest274> :P
[01:41:43] <Guest274> skunkworks: ok, seems to be working now
[01:42:03] <alex_joni> skunkworks: let me know if there's something else borken
[01:45:08] <alex_joni> * alex_joni is off to bed
[01:45:11] <alex_joni> g'night all
[02:07:37] <jymm> hola
[02:08:53] <JymmmEMC> Heh, my old job finally killed my account.
[03:56:39] <JymmmEMC> SWPadnos: hey
[06:34:01] <toastydeath> main screen turn on!
[09:54:43] <Vq^> what is the cause of the errormessage "Home switch inactive before start of backoff move"?
[09:55:00] <Vq^> why does it want to back off before the home-pulse?
[09:57:31] <alex_joni> Vq^: depends on the velocity signs
[09:57:51] <alex_joni> but it sounds like you have an intermittent switch
[09:58:01] <alex_joni> or you are homing to fast and got behind the switch
[10:01:51] <Vq^> i certainly didn't get behind the switch
[10:02:21] <Vq^> but it could be an intermittent switch
[10:03:32] <Vq^> i think i got the signs right because when it works it works very well
[10:11:13] <alex_joni> Vq^: try debouncing the switch
[11:12:38] <tomp> i know jepler used vlc to record movies of desktop actions. I didnt care to install vlc, and used a custom ffmpeg to do similar for the apt videos. this may be useful http://ubuntu.wordpress.com/2006/06/08/how-to-create-a-screencast-in-ubuntu/
[11:14:42] <alex_joni> how about xvidcap ?
[11:15:09] <tomp> i think it tried that ( over a year ago ) and it wasnt my final choice
[11:15:35] <alex_joni> ok
[11:15:43] <micges> hi
[14:28:47] <micges> cradek: around ?
[14:39:10] <micges> jepler: around ?
[14:39:21] <micges> help ?:)
[14:41:55] <alex_joni> micges: just ask..
[14:42:00] <alex_joni> they will reply when they get back
[14:54:47] <skunkworks_> alex_joni: irc works now - nice work
[14:58:50] <alex_joni> cool, thx
[14:59:52] <micges> bbl
[15:13:32] <alex_joni> bbl.. lunch
[16:03:01] <DanielFalck> tomp: did you have some videos of apt operations?
[16:59:21] <jlmjvm> skunkworks:what irc were you talking about earlier?
[17:01:22] <jlmjvm> jlmjvm is now known as hammerschlag
[17:10:58] <fenn> hammerschlag: linuxcnc.org website needed some security fixes, i suppose that broke the java irc client
[17:11:36] <hammerschlag> thanks fenn
[18:17:24] <tomp> DanielFalck: a year or more ago we discussed screen capture on the apt channel, i found this technique & a couple guys used it. I dont have any vids.
[18:21:24] <DanielFalck> tomp: ok.
[18:21:37] <DanielFalck> thanks
[18:21:38] <tomp> DanielFalck: alex_joni suggested Xvidcap which is a LOT easire ( but i get no sound with either :(
[18:21:58] <fenn> xvidcap doesn't work with opengl stuff
[18:22:04] <DanielFalck> you could always add the sound of a truck for apt : )
[18:22:11] <tomp> ? test file
[18:22:35] <fenn> at least not when i tried it
[18:22:42] <tomp> fenn: if i open an opengl app , then xvidcap wont grab it?
[18:23:18] <fenn> it will take one picture of it and then garble it up
[18:24:58] <fenn> you can see what i mean here http://fennetic.net/pub/irc/test-0000.mpeg
[18:25:01] <tomp> fenn: right, it's munged, the glxgears is frozen, but the xmms player 'scope' is fine...
[18:26:11] <tomp> oops, mouse tracks :(
[18:26:38] <fenn> it's supposed to be rotating and moving and such
[18:27:05] <tomp> gotcha
[18:32:32] <fenn> anyone seen this type of bug before? (hitting reload doesn't help, neither does zeroing g54 or g92.1) http://fennetic.net/pub/irc/g54-preview-bug.png
[18:37:58] <fenn> 5211..5213 were non-zero, goes away when emc is restarted (and the var entries go back to zero)
[18:40:46] <tomp> fenn: regarding desktop recording. xvidcap and ffmpeg do same with glxgears, the common problem is opengl ( not saying opengl is wrong, but havent found open src tool to handle it)
[18:40:57] <fenn> i see
[18:41:14] <fenn> well, the vlc scheme works
[18:41:35] <fenn> i'd think there would be a similar way to do it with X11 forwarding
[18:42:26] <tomp> ah, i didnt install the vnc server stuff yet
[18:46:57] <jepler> forcing the use of client-side software-only OpenGL rendering will probably solve the problem of recording an accurate opengl window image for a wide range of recording software packages
[19:09:58] <hammerschlag> jepler:how can i get my postgui_hal to work in the stepper inch sample config,i have everything working except this
[19:10:51] <hammerschlag> i placed the xml and postgui hal in the folder and added the posrgui line to the ini
[19:12:24] <jepler> hammerschlag: does emc run but without the stuff you specify in postgui?
[19:12:35] <hammerschlag> yes
[19:13:07] <jepler> then doublecheck the spelling in the inifile, make sure it's specified in the right section, and so on
[19:14:19] <hammerschlag> k
[19:15:10] <jepler> In emc 2.2 I just ran configs/sim/lathe.ini which uses [HAL]POSTGUI_HALFILE to show a virtual control panel -- it worked as I expected
[19:18:18] <jepler> fenn: When you set #5211, the rs274 parameter is set, but it does not affect the G92 offset immediately (it does if you issue G92.3)
[19:19:19] <fenn> i wasn't actually messing with the .var file, i thought it got written to automatically
[19:19:32] <jepler> fenn: however, when axis generates the preview it *does* apply the value currently in #5211 as the G92 offset (because it creates a fresh interpreter, and one step of the startup is much like G92.3)
[19:19:33] <fenn> maybe it was just left over from a previous run that got shut down wrong
[19:19:41] <hammerschlag> custom_postgui.hal:6: pin 'pyvcp.led.0' does not exist
[19:20:05] <hammerschlag> thats the error im getting
[19:21:18] <jepler> fenn: here's how I got something like what your screenshot showed: start emc, clear G92 and G54 offsets with the menu, MDI #5211=3, hit reload. When I hit reload, the preview moves over (because axis uses a G92 offset of 3 units in X, from the #5211 parameter), but when I hit run it's drawn where the old preview showed (because the G92 offset actaully in effect was 0 units in X)
[19:21:51] <hammerschlag> sorry didnt see what you said earlier,will check that config out
[19:22:38] <jepler> hammerschlag: two main reasons for that. First, you are mistaken about the pin name. in that case, comment out the 'link' or 'net' lines which give errors, then use 'halcmd show' or halshow to see what the proper pin names are.
[19:23:48] <jepler> second, your [DISPLAY]PYVCP line might be incorrect or missing, so that the control panel is not being loaded at all
[19:24:13] <jepler> commenting out the 'net' and 'link' lines will help you see if that is the case, because you can look whether the panel is shown onscreen or not
[19:26:00] <tomp> regarding screen capture: now i recall, vncrec requires Xvnc, also requires VNC 3.3.3r2 or RealVNC... some dependency hell, some config hell... thats why i used stuff like Xvidcap, (1 btn install, 1 btn run)
[19:28:19] <hammerschlag> k
[20:00:50] <hammerschlag> jepler:got it,thanks for telling me where that example was
[20:03:13] <hammerschlag> the problem was the display line was missing
[20:05:48] <JymmmEMC> SWPadnos SWPLinux ping
[20:10:14] <eric_U> back to latency issues again, darn it
[20:10:47] <JymmmEMC> eric_Unetwork or hardware?
[20:11:01] <eric_U> real time latency
[20:11:35] <JymmmEMC> eric_U One suggestion is to disbale devices in BIOS that you dont use.... Secondary controller, serial ports, etc.
[20:12:01] <eric_U> I think it was one of the x devices
[20:12:07] <eric_U> interrupt or such
[20:12:58] <eric_U> maybe not
[20:13:15] <JymmmEMC> I just noticed that I got a tad better results when things were disabled in BIOS that I dont need. Time consuming process, but might be worht a go.
[20:13:35] <eric_U> I actually went through and did that, thought it was the usb keyboard
[20:13:52] <eric_U> I've done this a lot
[20:13:55] <JymmmEMC> disable legancy support if you dont need it.
[20:14:15] <eric_U> always, as far as I know
[20:14:15] <JymmmEMC> If you mobo uses a ps2 kybd/mouse you could disable USB all together
[20:14:28] <eric_U> I like usb meeces
[20:15:11] <JymmmEMC> Well, try both ways, see what kind of results you get. USB is a big latency whore 9or can be that is).
[20:17:39] <eric_U> the latency test seems a little suspect. I do the latency test program and get some latencies on the order of 40 microseconds
[20:17:43] <eric_U> which isn't that great
[20:18:03] <eric_U> but the emc latency test gives me these results on the order of a millisecond
[20:18:21] <eric_U> when it says that there was an unexpected real-time delay
[20:18:48] <JymmmEMC> Can you disable USB in the BIOS all together?
[20:18:59] <JymmmEMC> not just legacy
[20:19:24] <eric_U> never, ever seen any latencies like that with the rtai latency tests, even with x programs running full blast
[20:19:34] <JymmmEMC> I'd tyr it if nothing else than for shits and giggles test.
[20:19:53] <eric_U> I'll have to dig up one of those usb-ps2 converters
[20:22:29] <eric_U> is there something like chkconfig on ubuntu to control services/daemons?
[20:22:40] <JymmmEMC> no lcue
[20:22:43] <JymmmEMC> no clue
[20:23:52] <eric_U> don't know why I would want to load a bluetooth module
[20:46:55] <JymmmEMC> or a toshiba touch screen
[20:47:24] <eric_U> what's the name of that?
[20:47:51] <JymmmEMC> Dont recall, I just see it upon bootup
[20:48:09] <eric_U> that's why I wanted something like chkconfig
[20:48:18] <eric_U> basically an rc.d editor
[20:48:23] <JymmmEMC> try dmesg | less
[20:48:37] <JymmmEMC> or dmesg | grep toshiba
[20:48:44] <JymmmEMC> or dmesg | grep touch
[20:48:55] <JymmmEMC> oh hang on...
[20:49:40] <JymmmEMC> sysv-rc-conf
[20:49:49] <eric_U> thaks
[20:49:51] <eric_U> n
[20:50:16] <JymmmEMC> you might have to sudo apt-get install it it
[20:51:58] <eric_U> is that in ubuntu system tools?
[20:52:12] <JymmmEMC> it's a consile application (terminal)
[20:52:37] <eric_U> I'm using a console, ssh'd in from a computer that sits where it's warm
[20:53:17] <JymmmEMC> sysv-rc-conf - SysV init runlevel configuration tool for the terminal
[20:53:35] <JymmmEMC> so, sudo apt-get install sysv-rc-conf
[20:53:47] <eric_U> tells me there is no such package for some reason
[20:54:17] <JymmmEMC> you might have to enable other despoistories
[20:54:43] <eric_U> probly
[20:55:50] <JymmmEMC> /etc/apt/sources.list then run apt-get update and it should show up
[20:56:11] <JymmmEMC> edit/uncomment in /etc/apt/sources.list then run apt-get update and it should show up
[20:56:23] <eric_U> thx, I'll try
[20:56:45] <JymmmEMC> *I* usually uncomment them all so I dont have to deal with it later, but YMMV
[20:58:09] <eric_U> that worked, thanks
[21:21:19] <eric_U> this is annoying: http://cgi.ebay.com/IDEC-Power-Supplies-at-www-controlsdirect-net_W0QQitemZ110224038626QQihZ001QQcategoryZ11772QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
[21:24:49] <archivist> advert spam
[21:25:33] <archivist> bid a dollar win it and complain when they dont ship
[21:25:36] <eric_U> thought about waiting until sellers can't leave feedback, buying and giving them a negative
[21:25:45] <archivist> hehe
[21:26:05] <eric_U> worth a dollar, they need a "flag" option like craigslist
[21:26:42] <eric_U> I guess there is one "report this item"
[21:26:52] <SkinnypuppY34> Inland Empire???
[21:26:56] <archivist> yup
[21:27:00] <archivist> odd
[21:27:14] <eric_U> I thought that was around sac california
[21:27:48] <SkinnypuppY34> I'd spend $1 to #^$% with em
[21:28:11] <eric_U> then report them to paypal
[21:28:15] <SkinnypuppY34> yep
[21:31:36] <eric_U> imana turn them in, prohibited to list "no item"
[21:35:52] <JymmmEMC> Everyone ask them the part number and shipping cost to your zip code =)
[21:35:58] <eric_U> silly, you can't add a comment
[21:37:31] <eric_U> seem to have good prices at their store though
[21:57:12] <JymmmEMC> I wonder how well emc would run on this... http://support.intel.com/products/motherboard/d201gly/index.htm
[21:58:44] <skunkworks> depends on the shared video memory.. to start
[21:59:52] <JymmmEMC> $69 @ frys, might be worth trying out.
[22:00:04] <skunkworks> you could always take it back :)
[22:00:10] <JymmmEMC> exactly
[22:00:25] <JymmmEMC> well, at outpost.com (same diff)
[22:02:28] <JymmmEMC> I hope it'll run on < 100Watt PS
[22:06:56] <jepler> fenn: looks like the spacing of the letters needs a little bit of work yet
[22:07:15] <jepler> fenn: have you figured out where the character width is stored in the cxf files? (I haven't even looked in the file)
[22:08:56] <eric_U> JymmmEMC, have a link at outpost?
[22:09:20] <JymmmEMC> outpost.com
[22:13:36] <eric_U> too bad about the 1 gig memory limit
[22:15:48] <eric_U> my wife just drove off in my car and screwed up my cellphone call
[22:16:13] <eric_U> gotta love bluetooth
[22:18:12] <eric_U> mobo sold out
[22:20:43] <alex_joni> eric_U: the 1 gig limit might be gone in the next version..
[22:20:51] <JymmmEMC> online yes, maybe in stores still
[22:25:26] <Roguish_> '
[22:29:51] <eric_U> why did I bother buying ground steel if it's going to have scratches and dings all over it?
[22:30:03] <eric_U> yeesh
[22:30:25] <eric_U> maybe I should return it, anyone ever return anything to enco?
[22:32:57] <SkinnypuppY34> Yeah they tried to get me to keep a damaged item , but a few minutes of complaining and e-mailing pics of their piss poor packing they paid return shipping and got me a new one in the mail
[22:33:34] <SkinnypuppY34> Dividing head looked like it went down a flight of stairs !
[22:35:42] <JymmmEMC> eric_U: I did, no problems
[22:36:06] <JymmmEMC> enco even sent a calltag too
[22:36:12] <JymmmEMC> iirc
[22:37:32] <tomp> cool, we had an order for 18 machines, which was gonna save our co. then there were street stories that the mfctr couldnt possibly make 'em fast enuf. i just got a a call from taiwan & they're committed to getting them out and committed to a schedule. phew! :-)
[22:49:13] <SkinnypuppY34> Can you specify other fonts for truetype-tracer?
[22:50:26] <BigJohnT> yes
[22:50:47] <BigJohnT> type in "man truetype-tracer"
[22:52:30] <SkinnypuppY34> Thanks for the man page
[22:57:16] <eric_U> man, too easy
[22:57:21] <eric_U> just try to guess the arguments
[22:57:52] <archivist> heh try to guess the arguments for woman
[22:58:16] <eric_U> pretty much standard procedure
[22:59:08] <eric_U> BigJohnT, didn't Alex Joni say he was going to be able to project fonts onto an arbitrary surface by today?
[22:59:41] <BigJohnT> a 3-D surface I think!
[23:00:17] <eric_U> yeah!
[23:00:38] <eric_U> did you get your gui done?
[23:01:12] <BigJohnT> no, was making parts today at my machine shop
[23:01:21] <BigJohnT> I did think about it some...
[23:01:24] <eric_U> cool
[23:01:50] <BigJohnT> trying to log in as root but it won't let me :(
[23:02:45] <jtr> sudo sh
[23:03:19] <BigJohnT> cool
[23:03:31] <BigJohnT> it took my password that time
[23:03:44] <BigJohnT> I was just doing su
[23:09:14] <jtr> sudo su works too - not sure there isn't another "preferred" way.
[23:13:16] <BigJohnT> I was just doing what was in my Linux book I had... thanks, now to get DevCpp installed...
[23:14:49] <jepler> BigJohnT: sudo -i or sudo -s to get a terminal as root
[23:15:20] <jepler> (one is a so-called "login shell; it has an efect on things like the PATH)
[23:15:41] <BigJohnT> ok, that is cool
[23:16:56] <jepler> sudo su or sudo bash are other ways to get an interactive shell
[23:19:18] <SkinnypuppY34> Anyone ever tried those bose noise cancelation headphones around machines?
[23:20:46] <eric_U> what kind of machine?
[23:21:54] <SkinnypuppY34> mill or lathe
[23:22:32] <SkinnypuppY34> Motor noise mostly
[23:22:46] <eric_U> I just buy the 32dB passive headphones
[23:23:34] <SkinnypuppY34> Got a link ? Been sayin HUH too much lately
[23:23:49] <eric_U> do the bose allow you to hear conversations?
[23:24:34] <SkinnypuppY34> Not sure someone suggested them but hadn't tried them either
[23:25:15] <eric_U> go to mcmaster and search for 9206T2
[23:25:40] <SkinnypuppY34> Integrated circuitry reduces ambient noise but lets you hear conversations.
[23:25:53] <eric_U> that could be an advantage
[23:26:19] <eric_U> most of the time I wear mine so I don't have to hear conversations
[23:26:23] <SkinnypuppY34> Oh earmuffs
[23:26:38] <eric_U> isn't that what the bose ones are?
[23:26:41] <SkinnypuppY34> Yeah I could still point at my ears and pretend
[23:27:37] <SkinnypuppY34> and audio
[23:27:51] <eric_U> batteries last 20 hours
[23:27:56] <eric_U> sounds expensive
[23:28:46] <eric_U> the $350 ones are rechargable
[23:29:18] <eric_U> they need a bluetooth version for safety
[23:29:39] <eric_U> or put an mp3 player in there
[23:30:04] <SkinnypuppY34> Yeah I'm wondering if I can cancel some noise and have low music db at the same time . Instead of the music competing with the machine both loud as (*^*
[23:30:40] <eric_U> noise canceling should work fairly well for machine noise
[23:31:13] <eric_U> that's too much $ for me though
[23:34:29] <eric_U> bose doesn't seem to spec out the attenuation
[23:48:02] <BigJohnT> Ok, I'm stuck. I have a CD that is owned by root. I tried to switch users to root (ubuntu 6) and it won't let me. I did a sudo -i in a terminal and that worked
[23:48:13] <BigJohnT> I still don't see all the files on the disk...
[23:48:35] <BigJohnT> I popped it into my windoz box and I know that they are there...
[23:48:51] <BigJohnT> do I have to reboot and start as root?
[23:54:04] <tomp> the device is owned by root, as root chg ownership, like sudo chown root:BigJohnT ... he left !
[23:56:44] <tomp> the device is owned by root, as root chg ownership, like sudo chown root:BigJohnT /dev/cdrom , you'll have to adjust for your device and your id/group
[23:57:04] <BigJohnT> tomp: thanks
[23:57:23] <tomp> then something like chmod a+r /dev/cdrom... best to do a man chown & man chmod
[23:57:41] <tomp> sudo chmod
[23:58:28] <tomp> oh, bet that leave/comeback was a reboot
[23:58:40] <BigJohnT> yep
