#emc | Logs for 2004-11-11

[01:55:55] <alex_joni> * alex_joni is back....
[02:00:42] <alex_joni> * alex_joni went home... later guys....
[05:01:11] <rayh> paul_c: You hanging around?
[05:30:33] <paul_c> back from Tea..
[05:33:39] <paul_c> alex_joni: Did you want to resend the email from yesterday...
[05:34:14] <alex_joni> paul_c: sorry?
[05:35:01] <paul_c> The one that you tried to send twice last night
[05:35:09] <alex_joni> I did resend it yesterday (because you said you didn't get it... thought the problem was on my side)
[05:36:51] <paul_c> the problem is more likely with my ISP
[05:37:12] <alex_joni> did you try the account I set you up?
[05:37:57] <paul_c> yes - But it wouldn't accept any outgoing mail
[05:38:13] <alex_joni> it accepts outgoing mail only with authentication
[05:38:29] <alex_joni> not sure how to set up that on your mail client
[05:50:30] <asdfqwega> * asdfqwega feels better - new, shiny laser ordered and on it's way
[05:51:44] <alex_joni> asdfqwega: congrats...
[05:51:49] <asdfqwega> Now, on to ebay sales. Anybody want a couple dozen Pentium 1's? You could use them to tile you bathroom!
[05:52:20] <alex_joni> * alex_joni watched a show last night on making gold out of computer scratch...
[05:53:24] <asdfqwega> Yeah, I know there's a guy in the UK who does it...It takes him several tonnes of scrap to get, what?, 8 or so lbs of unrefined precious metals?
[05:53:52] <asdfqwega> Several tonnes of computer board is pretty bulky.
[05:54:34] <alex_joni> hmmm.. I saw that 3 PC's have in them the same quantity of gold as do 3 tons of rock from africa...
[05:55:04] <asdfqwega> You should see the microgold mining that goes on in Arkansas, USA
[05:55:35] <alex_joni> when I'll get the chance ;)
[05:55:46] <asdfqwega> Foreign companies are mining US gold - and they sift through an entire mountain to get it
[05:56:20] <asdfqwega> Well...back outside, while the sun's shining and all that.
[05:57:48] <alex_joni> it's dark here...
[05:57:57] <alex_joni> so watch out... it's going your direction :D
[06:04:08] <alex_joni> paul_c: any luck?
[06:09:52] <paul_c> Nothing yet..
[06:10:11] <alex_joni> :(
[06:10:32] <alex_joni> what e-mail client are you using?
[06:12:02] <paul_c> kmail
[06:13:29] <alex_joni> kde3?
[06:14:09] <paul_c> yup
[06:14:14] <rayh> paul_c: Keith sent through another revised interp.
[06:14:43] <rayh> I sent him monday's sf *-new.
[06:15:38] <rayh> He said it would be rather easy to bring his stuff into line.
[06:16:02] <paul_c> Great...
[06:16:13] <paul_c> But could we have it in stages please
[06:16:20] <rayh> Don't know how long it will take him.
[06:16:31] <alex_joni> paul_c: it looks to me as KMail supports SMTPAuth (http://www.netfaqs.com/linux/Mail/KMail/New/index.asp?bisp=)
[06:17:05] <rayh> I'll ask. First the fixes, then the indenting or other way round?
[06:17:06] <paul_c> comments, indentation, and code in seperate patches - Makes it so much easier to see what has changed.
[06:17:24] <rayh> Gotcha.
[06:17:28] <paul_c> Fixes first would be best.
[06:17:33] <cradek> IMO, doesn't matter, but separate
[06:17:49] <cradek> (better yet, never reformat)
[06:17:49] <alex_joni> hello cradek
[06:18:03] <cradek> hello
[06:18:40] <cradek> always have to contribute my 2c
[06:18:58] <alex_joni> you contribute in EURO-cents?
[06:19:08] <cradek> I spent hours decoding an indent run + change in an emc file not long ago
[06:21:06] <rayh> paul_c: Mind if I give keith an eaddy for you?
[06:22:00] <cradek> I wonder how danfalck is doing with the website update
[06:22:08] <cradek> (I think it was him)
[06:22:21] <paul_c> rayh: Not a problem
[06:29:46] <alex_joni> I'm outa here...
[06:34:18] <alex_joni> bye guys...
[06:34:26] <cradek> heh
[06:34:30] <cradek> you keep saying that, but then you come back
[06:34:37] <cradek> we know you can't stay away
[06:35:42] <alex_joni> I know that too ;)
[06:35:55] <alex_joni> but it's late here...I'll be back tomorrow :P
[06:35:59] <cradek> ok then
[06:36:23] <alex_joni> was danfalck really doing a website update?
[06:36:31] <cradek> I think it was him
[06:36:32] <alex_joni> (or is?)
[06:36:39] <cradek> someone wanted emcplot3d screenshots, remember?
[06:36:47] <cradek> but I don't see them on the site yet
[06:36:50] <alex_joni> hmmm... didn't hear anything...
[06:36:55] <alex_joni> I see now...
[06:37:00] <alex_joni> let me check the logs ;)
[06:39:46] <alex_joni> yup... it was danfalck
[08:38:36] <robin_sz> eveny?
[08:38:45] <robin_sz> * robin_sz waves
[08:44:10] <paul_c> http://www.ai.mit.edu/projects/humanoid-robotics-group/index.html
[08:46:33] <robin_sz> hmmm
[08:46:38] <robin_sz> any of em run EMC?
[08:58:43] <paul_c> wouldn't have thought so - Not enough IO
[08:59:13] <robin_sz> ah well
[08:59:26] <asdfqwega> * asdfqwega waves
[08:59:56] <asdfqwega> Hey, Robin - good news and bad news
[09:00:09] <robin_sz> ... ??
[09:00:45] <asdfqwega> Good news - I was able to re-mount my lens, and with assist air, cut 1/4" oak with 0.010" kerf
[09:00:59] <robin_sz> kewl :)
[09:01:12] <robin_sz> bad news?
[09:01:19] <robin_sz> it cut your finger off?
[09:01:24] <robin_sz> you are now blind?
[09:01:41] <asdfqwega> Bad news - the doofus I got the laser from used speaker wire for the HV lines, so it took out one of my Xylotex drives
[09:01:50] <robin_sz> gah!
[09:01:56] <asdfqwega> AND I broke off an electrode when changing the wire
[09:02:01] <robin_sz> oops.
[09:02:06] <asdfqwega> And I mean BROKE
[09:02:09] <robin_sz> dang dang dang
[09:02:24] <robin_sz> vacuum still OK?
[09:02:30] <asdfqwega> Nope
[09:02:34] <robin_sz> ah ...
[09:02:56] <robin_sz> all is not lost!
[09:03:21] <asdfqwega> www.bright.net/~janfritz/Laser/laser-break.jpg
[09:03:38] <robin_sz> if you fill it with some coloured water and a little oil, it will make a nice lamp
[09:04:08] <robin_sz> 404
[09:04:17] <asdfqwega> Hm..
[09:04:44] <robin_sz> shame about the terminal though ...
[09:05:03] <robin_sz> did you pre-heat the tube near the electrode?
[09:05:18] <asdfqwega> http://www.bright.net/~janfritz/Laser/laser_break.jpg
[09:06:07] <robin_sz> ah yes.
[09:06:12] <robin_sz> technically ...
[09:06:22] <asdfqwega> No, he didn't have it soldered - some strange type of clip.
[09:06:27] <robin_sz> thats what the laser pros call 'fscked'
[09:06:48] <robin_sz> oh. so it was purely mechanical then, you pulled too hard?
[09:07:17] <asdfqwega> I didn't even pull too hard - it was ready to let go
[09:07:17] <paul_c> http://www.livejournal.com/users/eeymsmo/92545.html
[09:07:51] <robin_sz> oh. I would have thought if it was ready to break, there would have been a lot of leakage ... small cracks and all that
[09:08:04] <asdfqwega> However, there is still some good news
[09:09:02] <asdfqwega> I got in touch with Synrad, and the sales rep managed to snag me a 10W RF-excited unit with power supply - and it'll ship tomorrow
[09:10:02] <asdfqwega> Which was good - their nominal lead time is 4 weeks
[09:12:11] <asdfqwega> So I basically have until next Tuesday to have everything ready to bolt on the new one
[09:12:48] <robin_sz> kewl :)
[09:12:49] <asdfqwega> It's a damn shame this one broke - I was just starting to do some fretwork
[09:12:56] <robin_sz> but many dollars?
[09:13:15] <asdfqwega> Not too bad - $2400
[09:13:16] <robin_sz> or a free replacement?
[09:13:20] <robin_sz> hmmm ...
[09:13:48] <robin_sz> theres some guys doing chinese tubes and supplies for < 1000
[09:14:40] <robin_sz> do you know any lab technicians with glassware skills?
[09:16:04] <asdfqwega> Robin, I'm out in the freakin' sticks...Anything resembling a lab tech is over 100 miles away
[09:16:15] <robin_sz> heheh :)
[09:17:16] <asdfqwega> I know I could fix this tube, eventually - but I'd get the help of a neon shop
[09:17:41] <asdfqwega> They'd have the right glass's for the metal-glass seal, and the vacuum equipment
[09:18:06] <asdfqwega> then it's just a matter of my finding some gas mix for sealed tubes.
[09:18:34] <asdfqwega> But that's just become a mid-term project
[09:20:26] <asdfqwega> But with the new laser, I'll finally have real electronic control over power and on/off
[09:22:13] <asdfqwega> I'd love to see if I can do on-the-move modulation with EMC
[09:23:32] <asdfqwega> Probably with that M101, or other
[09:24:40] <robin_sz> some laser cutters do x pulses per mm
[09:25:27] <robin_sz> quite handy as you get the right amount of energy delivered in corners etc
[09:26:33] <asdfqwega> Ah, now I remember - I wanted to ask you about laser diode arrays
[09:26:52] <robin_sz> uh huh ...
[09:27:14] <asdfqwega> There's a few on ebay that are 45W - but they're 793nm wavelength
[09:27:22] <robin_sz> uh huh ...
[09:27:52] <robin_sz> these are bar arrays ...
[09:27:56] <asdfqwega> Have you ever heard of someone use one of those for cutting, directly?
[09:28:06] <robin_sz> deigned to illuminate a YAG rod
[09:28:19] <robin_sz> no. the output is too poor
[09:28:19] <asdfqwega> That's what I figured
[09:28:44] <asdfqwega> How's that?
[09:28:47] <robin_sz> its got huge divergence, and its not a single spot
[09:28:55] <robin_sz> its an array of spots ...
[09:29:37] <robin_sz> but ... point it at a YAG rod, you get 50% conversion and a nice low divergence beam
[09:30:00] <robin_sz> no use for wood though
[09:30:19] <robin_sz> wrong wavelength
[09:30:57] <robin_sz> mount it in your back windshield and blind tailgaters ;)
[09:31:19] <robin_sz> just like they do in fighter aircraft
[09:31:23] <asdfqwega> That's pretty much what I thought...that, and the power sensitivity of a diode array
[09:31:48] <asdfqwega> ?
[09:32:11] <asdfqwega> How are they supposed to blind tailgaters from an aircraft?
[09:32:49] <asdfqwega> It seems just as unlikely as the idea of making a computer-controlled laser turret for killing flys.
[09:33:00] <asdfqwega> flies :P
[09:33:53] <robin_sz> nah ..
[09:34:12] <robin_sz> thay use 'undreds and 'undreds of watts of diodes
[09:34:22] <robin_sz> illegal under the geneva convention ...
[09:34:34] <robin_sz> but apparently the desing, manufacture and sale isnt
[09:34:45] <asdfqwega> Who is doing this?
[09:34:51] <robin_sz> the 'illegal' bit is getting caught :)
[09:35:09] <robin_sz> using or making?
[09:35:14] <asdfqwega> using
[09:35:22] <robin_sz> officially: no one
[09:35:52] <robin_sz> but apparently there are at least 2 companies in the UK selling lots, or so Im told ;)
[09:36:21] <asdfqwega> Yeah, pull the other one
[09:36:28] <robin_sz> shrug.
[09:36:44] <robin_sz> search for 'laser dazzle weapons' on ebay
[09:37:54] <asdfqwega> Heh, sounds like the "laser, phaser, and ion ray gun" ads in the back of Popular Science Magazine
[09:38:21] <robin_sz> oh, looks like they are in use with british warships ...
[09:39:17] <asdfqwega> Oh, I imagine the major miltary powers are researching energy weapons

[09:40:29] <robin_sz> anyway ...
[09:40:36] <robin_sz> back to CNC ...
[09:40:46] <paul_c> Either Dan has woken up, or a small has hacked the keyboard
[09:40:59] <asdfqwega> a small?
[09:41:12] <paul_c> child
[09:41:23] <robin_sz> a client asked for some mods to the plasma yesterdy ... by lunctime they were designed, lasered, pressed and fitted :)

[10:08:20] <danfalck> oiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii
[10:08:33] <robin_sz> oi indeed
[10:08:58] <paul_c> * paul_c goes for a reboot
[10:09:06] <robin_sz> * robin_sz throws danfalck's rug-rat a fish
[10:11:46] <tbl> sadly, paul is sleeping!
[10:11:58] <tbl> speaking of the devil
[10:11:59] <tbl> hey paul
[10:12:29] <tbl> I am having some trouble putting grub down on an rc-46 box, any reccomendations on doing it manually?
[10:12:40] <tbl> (booting from cdrom)
[10:13:03] <tbl> grub-install --root-directory=/mnt/hda3/boot /dev/hda
[10:13:07] <tbl> is what i am trying now
[10:13:17] <paul_c> the installer should do it all for you
[10:13:25] <tbl> it stalls
[10:13:32] <tbl> durring the installer, so i killed it
[10:13:40] <paul_c> check the md5sum
[10:13:46] <tbl> mmm k
[10:14:42] <paul_c> in the meantime, how are we going to get the next beta release up to Ray to test ?
[10:14:59] <tbl> i can host it if you want
[10:15:20] <tbl> put it someplace i can fetch it form
[10:15:24] <tbl> fromm
[10:15:51] <paul_c> OK - I'll email you with an ip addy/file.name
[10:16:36] <tbl> mjoyce@inertiacnc.com
[10:16:50] <tbl> brb, rebooting
[10:18:19] <tbl_> so yeah
[10:18:53] <tbl_> what is a maximum time i should expect while running grub-install durring the installer?
[10:19:45] <paul_c> seconds
[10:22:22] <tbl_> well, it is taking 10+ min
[10:22:28] <tbl_> on a 2.2ghz p4
[10:22:47] <paul_c> that CD sounds like it is borked
[10:23:01] <tbl_> def not
[10:23:04] <tbl_> md5 matches
[10:23:32] <tbl_> and i have used this to install on other machines no problem
[10:23:38] <tbl_> maybe this particular motherboard has issues?
[10:23:50] <cradek> ide?
[10:24:02] <tbl_> yes
[10:24:04] <tbl_> pata
[10:24:10] <tbl_> (btw sata doesn't work)
[10:24:31] <cradek> is it jumpered cable select and the others have been master?
[10:24:34] <paul_c> sata needs some screwball hacks
[10:24:51] <tbl_> it is jumpered to master, single drive
[10:24:55] <paul_c> * paul_c was reading up about it the other night
[10:25:05] <tbl_> tbl_ is now known as tbl
[10:25:50] <tbl> I would just really like to ship out this unit today, but it lacks a working boot loader.
[10:26:34] <cradek> yeah, that seems non-optimal
[10:28:14] <tbl> any idea's paul?
[10:28:46] <paul_c> apt-get install lilo ?
[10:28:58] <tbl> haha, i have to be able to boot into the os first
[10:29:29] <cradek> install grub on floppy
[10:29:33] <paul_c> No... Do it on the Live
[10:31:11] <paul_c> and do the lilo install from the CD
[10:31:26] <tbl> interesting, let me try that
[10:31:29] <paul_c> (or you could use a boot floppy and re-install grub)
[10:31:30] <tbl> (hate lilo btw)
[10:31:36] <tbl> yeah i would rather do that
[10:32:55] <tbl> the install script keeps erroring because there is a lack of proc
[10:32:57] <tbl> (lame)
[10:35:50] <paul_c> Ah... Simple
[10:36:18] <tbl> simple, as in simple fix?
[10:36:41] <paul_c> check mount to see if proc is mounted in the chrooted environ
[10:38:18] <tbl> (it's not)
[10:38:59] <paul_c> is proc shown as mounted anywhere ?
[10:39:03] <tbl> nope
[10:39:21] <tbl> only thing mounted is /mnt/target
[10:39:26] <paul_c> mount proc
[10:39:28] <tbl> which happens to be linked to /dev/hda3
[10:39:54] <tbl> it says its already mounted if i try to mount it
[10:40:06] <tbl> however, if i df, it gets errors
[10:40:24] <tbl> umount: proc seems to be mounted multiple times
[10:40:26] <tbl> =(
[10:41:29] <tbl> oh well, i am passed the ups cutoff, guess it isn't goign out todday
[10:42:11] <paul_c> mount -t proc /proc /proc
[10:43:01] <cradek> tbl: you left sherline?
[10:43:05] <tbl> yes
[10:43:21] <cradek> and now you're building emc machines somewhere else?
[10:44:17] <tbl> paul that has no effect
[10:44:22] <tbl> cradek, http://inertiacnc.com
[10:44:38] <cradek> well congrats, hope you're enjoying it
[10:44:43] <tbl> yeah its good
[10:45:21] <cradek> um I think you need a front page or something
[10:45:42] <tbl> you don't see the e-commerce site?
[10:45:58] <cradek> yeah but it's empty
[10:46:05] <cradek> This is a default setup of the osCommerce project, products shown are for demonstrational purposes, any products purchased will not be delivered nor will the customer be billed.
[10:47:01] <tbl> yeah i just installed osCommerce today
[10:47:05] <tbl> i added some categories
[10:47:15] <tbl> if you look on the left
[10:47:32] <cradek> gotcha
[10:48:11] <cradek> (This site is designed in FrontPage and is best viewed with Microsoft Explorer. Some photos may appear out of position when viewed in Netscape or other browsers.)
[10:48:32] <cradek> I see you didn't get sherline to go with your new design, that's too bad
[10:49:34] <tbl> lol yeah
[10:49:40] <tbl> i didn't do any web development for sherline
[10:49:41] <tbl> except for like
[10:49:46] <tbl> http://sherline.com/emc/ud/
[10:51:44] <cradek> yikes, it hurts to see all those emc bugs listed in one place
[10:53:42] <tbl> haha it is outdated
[10:53:44] <paul_c> but look at how many are left without a fix.
[10:54:16] <cradek> yep
[10:54:18] <cradek> I see that
[10:54:32] <tbl> all of those issues are fixed i think
[10:54:51] <tbl> paul
[10:54:57] <tbl> any idea's on getting grub on this box?
[10:55:39] <tbl> proc is now mounted, and i am doing grub-install --root-directory=/mnt/hda3 /dev/hda
[10:55:46] <tbl> to no avail, it appears to be locked.
[10:56:02] <paul_c> mount --bind /proc /mnt/target/proc
[10:56:30] <cradek> tbl: did you make sure you have boot sector (virus) protection turned off in the bios?
[10:56:46] <cradek> (if it has it)
[10:57:11] <tbl> yeah it's off
[10:57:59] <cradek> you've done machines just like this? it must be some kind of hardware issue
[10:58:08] <tbl> no
[10:58:12] <tbl> this is a new hardware configuration
[10:58:27] <tbl> new motherboard at least
[10:59:16] <paul_c> tbl: http://issaris.org/rtai/
[11:00:51] <tbl> real time operations run fine
[11:01:05] <tbl> its just grub
[11:01:10] <tbl> grub is a pos i tell ya!
[11:01:17] <tbl> oh and apt-get install lilo doesn't work
[11:02:45] <cradek> I still think you should install grub on floppy and reboot
[11:02:54] <paul_c> did you do an apt-get update first ?
[11:04:03] <paul_c> * paul_c concurs with cradek - Make a boot floppy.
[11:06:06] <paul_c> YeeHAAA !!!
[11:06:27] <cradek> ??
[11:06:37] <paul_c> The first BDI-3.xx installed & booted
[11:06:44] <cradek> slick
[16:31:26] <danfalck> cradek: are you there?
[16:32:21] <danfalck> cradek:I haven't forgotten about putting the screenshots up yet.
[16:32:46] <danfalck> cradek: just have to confer with Steve(owner of server) a bit.
