[00:00:10] <alex_joni> Jacky^: there is no other way to learn things (but burn something once in a while)
[00:00:54] <Jacky^> alex_joni: 30-40 ic's should be enough now ..
[00:01:06] <Jacky^> I can also stop now :)
[00:01:14] <alex_joni> suppose so.. but you could turn to mobo's
[00:01:23] <alex_joni> that's more interesting ;)
[00:01:27] <Jacky^> lol
[00:01:32] <Jacky^> :D
[00:01:46] <Jacky^> i switched to parport
[00:01:49] <Jacky^> its funny
[00:01:58] <Jacky^> not so much after the third :\
[00:03:37] <rayh> Hi alex_joni
[00:04:00] <alex_joni> ohhh.. hello rayh
[00:04:05] <alex_joni> long time no see ;)
[00:04:34] <rayh> Has been a while. How you doing?
[00:04:45] <alex_joni> on the run lately :(
[00:05:04] <alex_joni> right now I'm the closest to home I've been in the last 4 weeks
[00:05:10] <alex_joni> about 600 km away
[00:05:18] <rayh> I know that feeling. -- on the run that is.
[00:05:34] <rayh> Where are you?
[00:05:39] <alex_joni> probably I'll be away next week too
[00:05:56] <alex_joni> right now, I'm in a mountain resort (called Poiana Brasov)
[00:06:04] <alex_joni> about the middle of romania
[00:06:32] <rayh> Getting back home soon, I hope.
[00:06:43] <alex_joni> not sure
[00:06:51] <alex_joni> maybe I'll be home this weekend
[00:06:54] <rayh> resort. that doesn't sound right.
[00:07:06] <alex_joni> heh ;)
[00:07:12] <alex_joni> it's a ski-resort
[00:07:19] <alex_joni> but no skiing right now :)
[00:07:21] <alex_joni> no snow yet
[00:07:23] <Jacky^> hello rayh
[00:08:26] <rayh> Hey Jacky^
[00:28:59] <alex_joni> night fellows
[00:29:06] <alex_joni> * alex_joni finished checking mails ;)
[00:34:17] <icee> so, can anyone recommend any software to convert gerber PCB masks to tool paths for milling?
[00:34:39] <icee> I see that eagle can generate an outline and tool path.. but i have an orcad license and would prefer to use it
[00:40:23] <paul_c> http://www.yty.net/cnc/ has/had a script to do something along those lines.
[00:47:14] <icee> paul_c: he's using eagle. i did find a script called 'cam.py' from MIT that seems to be pretty nice tho.
[00:55:10] <Jacky^> G night
[00:58:41] <lilo> [Global Notice] Hi all. As noted earlier, Peer-Directed Projects Center, the world's smallest not-for-profit org and the parent org of freenode, is on the move temporarily to Waco, Texas, due to Hurricane Rita. If you're in the Waco area and you might be able to provide transportation, *local* bandwidth or other resource, please email your RL contact info as soon as possible to hurricane@freenode.net .... thank you!
[01:05:21] <paul_c> that looks like a new face..
[01:06:17] <gromit68> hikids
[01:06:33] <paul_c> Hrrmmm.
[01:06:55] <gromit68> i have a number of stupid questions, your patience is appreciated in advance
[01:07:59] <paul_c> depending on how stupid the questions.... You might get some silly answers, but we'll try.
[01:09:09] <gromit68> great. I have a lovely packard bell approx 300mhx that I would like to put the bdi into, but the pc does not recognize any cd as a boot disk, I have tried multiple combinations in the bios to force booting from cd, but I get the same result every time
[01:09:33] <Jymmm> did you md5sum the download?
[01:09:50] <paul_c> does it work with other bootable disks ?
[01:09:51] <gromit68> see, this is the thing, it all looked so simple...
[01:09:53] <icee> and how did you burn the cd?
[01:10:33] <Jymmm> paul_c "Well, that was a silly answer you gave!" =)
[01:10:38] <gromit68> so i come to the experts to humbly seek advice... from the beginning, in simple words, speak verrry slowly
[01:10:55] <paul_c> * paul_c hands Jymmm a sock.
[01:10:57] <Jymmm> did you md5sum the download?
[01:11:13] <paul_c> * paul_c hands Jymmm another larger sock. ;)
[01:11:15] <icee> gromit: how did you burn the cd?
[01:11:19] <gromit68> don't know what md5sum, is, so I'll say no
[01:11:42] <paul_c> Let's see if the machine will boot from CD first guys.
[01:12:10] <gromit68> to burn, I used whatever burn software runs under mr gates' virus
[01:12:17] <paul_c> what is the model number of the computer ?
[01:12:24] <icee> paul_c: well, i've run into a lot of people burning ISO files onto a new CD filesystem, rather than an image
[01:12:27] <gromit68> I'll go grab the model #
[01:12:51] <icee> paul_c: so they have a CD with one big file on it, newcd.iso ;)
[01:13:02] <paul_c> icee: That is indeed a common mistake
[01:13:12] <paul_c> One beer mat.
[01:13:21] <icee> gromit: if you put the CD in and double click on it under my computer
[01:13:24] <icee> do you see any files on it?
[01:14:27] <gromit68> as you say, iirc it shows only one file *.iso
[01:14:51] <icee> OK, gromit, you need some cd burning software that will let you burn it as a cd image
[01:14:55] <gromit68> ok
[01:15:03] <paul_c> nero 6
[01:15:12] <gromit68> beauty
[01:15:12] <icee> yah, you can download an eval of nero
[01:15:26] <Jymmm> * Jymmm smacks paul_c with the smelly socks.... told ya you were wrong! =)
[01:15:52] <gromit68> you can read and read until your eyes bleed, but you get a hundred different opinions
[01:16:11] <gromit68> I wanted answers from someone who already learned the hard way
[01:16:50] <gromit68> do I have to do anything special when I download the iso in the first place?
[01:17:00] <icee> gromit: you shouldn't have to, no
[01:17:20] <Jymmm> md5sum it to save from burning coasters
[01:17:56] <paul_c> Jymmm: Did you know, Alt+Z makes your text go backwards in most IRC clients?
[01:17:59] <paul_c> .ereh ti did I ?eeS
[01:18:32] <gromit68> let's suppose it burns successfully, then what?
[01:19:01] <icee> then leave it in the drive, and if your bios is set properly, when you reboot you'll boot off it
[01:19:14] <Jymmm> gromit68 http://theopencd.sunsite.dk/md5.php
[01:19:16] <paul_c> Which version did you download ?
[01:21:04] <paul_c> To check the CD is OK after burning, you can enter "linux mediacheck" at the first boot screen..
[01:21:11] <gromit68> bdi live rc46-1
[01:21:32] <paul_c> Ug... Old release.
[01:21:58] <paul_c> How much memory does the old 'puter have ?
[01:22:15] <gromit68> jon elson has a link to an update
[01:22:22] <gromit68> not sure on the memory capacity
[01:22:35] <gromit68> if I get something to work, I will gladly invest in more pc
[01:23:10] <paul_c> To be honest, BDI-Live is depreciated, old, out of date, unsupported.
[01:23:11] <gromit68> I just want to see something, anything..... buhler? buhler?
[01:23:37] <gromit68> ok, recommendations are appreciated
[01:23:59] <paul_c> anyways - Did ya find the model number ?
[01:24:15] <gromit68> sticker on case shows model 1985
[01:24:29] <paul_c> That sounds like a date code..
[01:24:54] <gromit68> no, it is a win98 machine
[01:24:55] <jepler> 1985 would be a pretty old computer
[01:25:07] <jepler> well, a pretty old PC, let's say..
[01:25:38] <gromit68> processor is amd k6
[01:25:43] <jepler> I don't think win85 was much to look at
[01:25:50] <paul_c> 72 pin EDO sticks if this google hit is to be believed
[01:26:40] <Jymmm> paul_c $9.98
[01:26:47] <Jymmm> did I guess right?
[01:27:31] <jepler> I like this "ideq" so far, but the color-changing LED front panel is going to drive me nuts if I spend much time in front of it
[01:27:33] <paul_c> gromit68: If you have a paltry 64Meg in there, don't even bother burning another CD.
[01:27:39] <jepler> the blinding blue drive activity LED isn't my favorite either
[01:27:46] <paul_c> You won't have enough memory to run it.
[01:28:33] <Jymmm> jepler sounds liek my ext hdd case
[01:29:20] <jepler> Jymmm: ideq is a small-form-factor PC
[01:29:31] <jepler> http://emergent.unpy.net/index.cgi/ideq
[01:29:32] <Jymmm> jepler ah. pic?
[01:29:49] <Jymmm> ah
[01:30:13] <jepler> it's a bit wider than a standard tower case, about as big, but only about 7" tall.
[01:30:14] <Jymmm> jepler anything particularrly special about it?
[01:30:43] <gromit68> 64 mb, yes
[01:30:45] <jepler> nothing all that special, no. I just wanted something new, small and quiet to replace a couple of older machines
[01:31:13] <jepler> it won't be running EMC, 2GB and a 64-bit processor would be wasted on that...
[01:31:31] <gromit68> whoa
[01:32:17] <Jymmm> jepler http://centralcomputer.com/products.asp?pline=HSYSB
[01:32:32] <gromit68> packard bell, fr500bios v1.03, base mem 640k, ext mem 62464, cache 512, 6.5 M hd
[01:33:19] <jepler> Jymmm: something in particular to look at there? I chose ideq 220k because it had AMD64 support, was not an nforce chipset, and was $100 less than some of the other models.
[01:33:50] <Jymmm> jepler No, just mini cases
[01:34:46] <jepler> keeping in mind that I've only had this since earlier today, I believe I'd recommend it to someone considering SFF.
[01:35:41] <Jymmm> jepler oh, you just bought the case. nm.
[01:36:00] <jepler> thanks anyway
[01:36:14] <Jymmm> jepler paul_c's smelly socks are making me light headed over here
[01:37:03] <paul_c> gromit68: 64Meg. That will not run Live I'm afraid...
[01:37:36] <paul_c> And you will only be able to do a text install with BDI-4.29
[01:37:41] <gromit68> I dont' need to run live, it just seemed convenient
[01:37:56] <paul_c> (and that is broken at the XFree86 config stage)
[01:37:58] <jepler> Jymmm: that web page I sent you to is my own notes about the machine
[01:38:38] <Jymmm> jepler only looked at the pic... thought the rest was a wish list.
[01:39:47] <jepler> Jymmm: the software is still all a wishlist, just getting it installed now
[01:39:58] <jepler> Jymmm: the hardware is real as the smell of, er, paul's socks
[01:40:28] <Jymmm> jepler hopefully not as harsh
[01:44:32] <paul_c> jepler: They were clean, washed socks.
[01:45:10] <gromit68> some kind of problem on nero's site, the demo not offered by itself, I'll scrounge something similar on tucows
[01:48:30] <jepler> paul_c: sorry, I was acting based on gossip
[01:48:39] <jepler> paul_c: could you add something about your socks to the wiki, to avoid future confusion?
[01:52:30] <Jymmm> paul_c : http://www.amazon.com/exec/obidos/tg/detail/-/043964948X/102-1917594-6462550?v=glance
[01:55:23] <paul_c> * paul_c mumbles something about reading ages & Jymmm's taste in the literary arts.
[02:00:55] <Jymmm> paul_c: Um that was YOUR recommended reading list. If yo uwant to see mine, llet me know when I get back from dinner.
[02:01:59] <gromit68> thanks for your help, guys, I'll be back to bother you more, I promise
[02:02:57] <paul_c> Jymmm is the expert..
[02:03:19] <paul_c> * paul_c drops Jymmm in the deep end.. ;)
[02:40:33] <lilo> [Global Notice] Hi all. If you are in Houston, Texas, USA and heading for Waco tomorrow, if you have a pickup truck and a fifth wheel hitch and are able to drive along that route, please message me. Thanks.
[10:07:24] <anonimasu_> morning
[15:49:11] <rayh> rayh is now known as rayh-away
[15:54:53] <rayh-away> rayh-away is now known as rayh
[15:56:05] <rayh> I need some help with a pci modem under 4.27.
[15:57:33] <paul_c> One of those winmodems ?
[16:00:31] <rayh> No it is supposed to be a USR hardware modem.
[16:00:45] <rayh> I can't understand what I read with lspci
[16:03:07] <paul_c> Check /proc/ioports and see if you have three or four serial ports listed.
[16:03:23] <paul_c> cat /proc/ioports | grep serial
[16:04:14] <paul_c> I'll bet you have a ttyS2
[16:05:03] <rayh> I do have a b400 device listed
[16:06:17] <paul_c> in addition to the usual 02f8 & 03f8 ?
[16:06:32] <rayh> Yep
[16:06:44] <rayh> I've got ttyS0-4
[16:06:45] <paul_c> That will probably be your modem then.
[16:08:04] <paul_c> Last time I meesed with PCI modems, I had to use ttyS2 in kppp
[16:11:32] <rayh> Okay. Thanks for the help. I'll keep playing.
[16:12:01] <rayh> I see that with the revised kppp setup, you can not select a device and then switch tabs and test.
[16:12:19] <rayh> You must save the selected device and then go back into edit to test it.
[16:13:53] <paul_c> Query Modem not work ?
[16:18:05] <rayh> Not until you've saved the device name.
[16:18:22] <rayh> Then on the next edit of the thing it will. The older kppp was much nicer.
[16:18:26] <rayh> faster
[16:21:44] <rayh> Not going to do it on any ttyS
[16:24:13] <paul_c> /dev/ttys2 ?
[16:32:24] <rayh> Nothing
[16:32:45] <rayh> even added rayh to tty group and nothing.
[16:32:58] <rayh> How do I allow myself to log in as root?
[16:33:23] <rayh> Guess I could go find that in the list archive
[16:34:46] <paul_c> JMK put some tweaks up on http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?BDI4Tweaks

[22:29:15] <Jacky^> ouch
[22:29:18] <alex_joni> buona notte
[22:29:19] <Jacky^> ciao alex_joni :)

[22:30:40] <alex_joni> ciao anna_emc
[23:28:47] <Jacky^> hey Yuga !
[23:28:58] <Jacky^> i was worried ..
[23:32:55] <anonimasu> hm
[23:33:55] <anonimasu> ValarQ: huydralica?
[23:33:56] <anonimasu> s
[23:33:59] <anonimasu> ValarQ: fun fun!
[23:34:00] <anonimasu> :D
[23:34:45] <Yuga> lo there Jacky^
[23:34:53] <Yuga> what u worried about Jacky^?
[23:35:42] <zwelch> paul_c: so i have been working today on getting the sim_rtapi.c bits working
[23:35:47] <Jacky^> hey Yuga
[23:35:59] <Jacky^> what woried ?
[23:36:10] <Jacky^> where youre has been ??
[23:36:12] <Yuga> <Jacky^> i was worried ..
[23:36:13] <Jacky^> all the time ?
[23:36:21] <Jacky^> O_O
[23:36:24] <zwelch> paul_c: i have a fairly clear idea of what i need to implement, assuming that the rtai_rtapi.c is a w roking example
[23:36:36] <zwelch> s/w ro/wor/
[23:37:13] <zwelch> one question that i can't trivially find answer is the requirement for both "free-running" and "periodic" tasks
[23:38:05] <zwelch> i was wondering if either a) pthreads has evolved and now supports the later form of thread, or b) i'll need to fake it somehow
[23:38:42] <zwelch> * zwelch thinks he needs to fake it
[23:40:29] <paul_c> You need a periodic thread... pthreads will not hack it.
[23:41:08] <zwelch> well, it can be made to simulate it
[23:41:50] <zwelch> i.e. the 'wrapper' function just loops around calling the 'taskcode' until the thread is stopped
[23:42:05] <zwelch> (delaying between calls, as appropriate)
[23:43:21] <zwelch> the only difference will be no ability to see it fired *exactly* so often (though the loop code can try to cope with latencies somewhat)
[23:43:54] <zwelch> for a non-RT simulator, that should do okay, right?
[23:45:30] <paul_c> run it with itimers or a busy wait loop.
[23:46:07] <paul_c> you could even use the timers wrappers in libnml if you wanted to.
[23:47:04] <zwelch> cool, i'll look at that
[23:48:39] <zwelch> (though that would violate "layering", unless we can factor out those bits into a convenience library built before rtapi)
[23:50:38] <paul_c> libnml is totally independant of rtapi and the pile... that is hal.
[23:54:04] <zwelch> right, so it would be better to add code to rtapi to satisfy this; that will keep rtapi from depending on libnml
[23:56:08] <paul_c> libnml already has timer functions, shared memory handlers and mutex wrappers.
[23:56:27] <paul_c> Why duplicate code in rtapi/ for the hell of it ?
