[01:40:00] <archivist> hehe hes started on you now fenn
[01:42:07] <fenn> meh
[01:42:50] <archivist> been going on and on and on......
[01:43:16] <archivist> 2:42 am here time for home I think
[01:58:34] <fenn> gn8
[02:01:31] <archivist> see ya
[13:06:12] <Sweeper> mm, finished my 3-axis stepper controller last night :D
[13:06:21] <Sweeper> testing will have to wait till tonight tho :(
[13:18:42] <BigJohnT> sweet Sweeper do you have pics
[13:28:01] <als> hey does anyone know if K'zan got cutter comp working?
[13:32:07] <assargadon> Hi there
[13:32:58] <als> hello
[13:34:22] <assargadon> I'll continue my work today at least :)
[13:34:31] <assargadon> After a hude amount of time...
[13:57:39] <als> K'zan gets this message, Log on 2008/06/16 "Cutter gouging with cutter radius comp" I believe he needs to make a short XY move after calling radius comp like G01 X.5Y0F?
[13:59:06] <als> if someone could mention this to him if he come back in
[16:01:05] <skunkworks> part of the forcast today includes 'light tornadoes'
[16:11:18] <tomp> fenn: ineteresting cairo app, sorta but not really cad http://www.entidi.it/adg/
[16:24:14] <fenn> eh ok, it's a decent start but not much there.. not even up to 'sketchpad' level
[16:31:03] <renesis> eagle pcb is pro one of the best CAD apps for linux
[16:31:06] <renesis> *prob
[16:31:46] <renesis> like, offset/trim/extend is the only thing i can think off it doesnt so well
[16:32:16] <renesis> qcad works but mostly it just feels like autocad but not as good
[16:35:25] <BigJohnT> renesis: what kind of "feel" do you think is best?
[16:37:12] <fenn> people tend to prefer whatever they started with
[16:38:12] <renesis> autocad is perfect
[16:38:18] <BigJohnT> that's understandable
[16:38:19] <renesis> and no i didnt start on that
[16:38:28] <renesis> and qcad is ribbonsoft leftovers
[16:38:32] <renesis> it feels as such
[16:39:07] <renesis> eagle is basically console cad with worlds worst gui and most fucked up learning curve ever
[16:39:15] <BigJohnT> I'm spoiled on Solidworks
[16:39:25] <renesis> that doesnt work in linux
[16:39:33] <renesis> and autocad is better for 2d i think
[16:39:34] <BigJohnT> and cost $5k
[16:39:42] <renesis> no its free, trust
[16:39:46] <renesis> so is autocad
[16:40:01] <renesis> * renesis only uses free software
[16:40:01] <BigJohnT> I know
[16:40:49] <renesis> the dimensioning stuff in SW is like overkill for simpler 2D shit
[16:41:10] <DanielFalck> good morning rayh
[16:41:12] <renesis> instead of drawing it and then defining it and dealing with possibly conflicting relations, in acad you just draw it
[16:41:17] <rayh> Hi Dan
[16:41:33] <DanielFalck> rayh: how was fest?
[16:41:41] <rayh> Good.
[16:41:41] <renesis> but yeah for 3d, especially simple 3d and assemblies, SW is very very fast
[16:41:44] <BigJohnT> I can do 2d print faster in SW by making a 3d model first than I can in ACAD
[16:41:53] <renesis> im going to do all the cabinets at my work in sw
[16:42:09] <K`zan> test
[16:42:15] <renesis> yeah but thats not 2d thats a mechanical drawing of a 3d part
[16:42:33] <renesis> anything involving 3d solidworks is just gonna be better than acad at
[16:42:40] <renesis> i wont even touch acad 3d
[16:43:09] <renesis> but yeah, i like drawing, so autocad workflow is very neat for drawings
[16:43:21] <BigJohnT> for 2d work I make a model in SW then save the print as ACAD then open it up in MC
[16:43:28] <renesis> i dont like the 2d editor in SW so much unless im sourcing the parts from the 3d editor
[16:43:42] <renesis> yeah thats alot more work than just drawing it
[16:43:52] <BigJohnT> not really
[16:44:06] <renesis> you have to draw it twice and do file export bs
[16:44:11] <renesis> instead of, new, draw, save
[16:44:20] <BigJohnT> oh no only have to draw it once
[16:44:55] <renesis> oh i read wrong
[16:44:58] <renesis> yeah thats not so bad
[16:45:07] <renesis> if i had to choose one or the other, id have to go with sw
[16:45:15] <renesis> but nothing beats acad at 2d
[16:45:28] <renesis> thats like the only bloatware app i use i feel like its perfect
[16:45:37] <BigJohnT> I can still make a model and a drawing in SW faster than in ACAD
[16:45:52] <renesis> depends on what it is
[16:46:07] <renesis> in autocad im mostly just typing on the console, and shit is happening
[16:46:19] <fenn> are you guys done yet?
[16:46:23] <renesis> i dont even mouse much
[16:46:29] <BigJohnT> I am
[16:46:45] <renesis> no im willing to babble on about this forever if people keep going on about it
[16:46:46] <renesis> * renesis shrug
[16:48:33] <fenn> tomp: i'd rather use an object oriented language than some c object library
[16:48:50] <fenn> adg is more trouble than it's worth
[16:54:15] <fenn> goocanvas provides almost all the functionality except chamfers and radiuses (?)
[16:56:21] <tomp> fenn: i'll look into goocanvas, thx
[17:05:28] <Anastasia> Anastasia is now known as K`zan_emc
[17:46:59] <JymmmEMC> SWPadnos: ping
[17:47:07] <SWPadnos> poing
[17:47:12] <JymmmEMC> lol
[17:47:21] <SWPadnos> sill hot there?
[17:47:23] <SWPadnos> still
[17:47:31] <SWPadnos> I guess the sill would be too
[17:48:27] <JymmmEMC> SWPadnos: I've been reading some thigns where a dedicated application is being tossed in an FPGA and runs MUCH faster than current pc/cpu's. Any trith to that?
[17:48:38] <JymmmEMC> truth
[17:48:40] <SWPadnos> for some applications, it's quite true
[17:49:04] <JymmmEMC> SWPadnos: Like how much faster and in what case?
[17:49:06] <SWPadnos> the last couple versions of Altium Designer have the ability to turn some C functions into dedicated hardware
[17:49:10] <skunkworks> 65deg here
[17:49:11] <SWPadnos> hundreds of times faster
[17:49:34] <SWPadnos> things like video processing, where you have a particular pipeline you need to push a lot of pixels through
[17:49:39] <SWPadnos> other DSP-like things
[17:50:13] <SWPadnos> that works best when the CPU is also embedded in the FPGA, I think
[17:50:16] <JymmmEMC> SWPadnos: So number crunching being the biggest performance increase over running on a Quad core 3GhZ?
[17:50:24] <SWPadnos> generally getting data into/out of a processor core is a bottleneck
[17:50:56] <SWPadnos> doing a specific sequence of operations on a stream of data would tend to have the greates tspeedup, I'd think
[17:51:11] <SWPadnos> but on a cost basis, the quad core CPU is probably still a better "deal"
[17:52:05] <SWPadnos> there wasa socket-940 high gate count FPGA available for a while, but it was $9000 or so
[18:08:53] <jepler> a specific example: http://www.madboa.com/geek/openssl/#benchmark-speed says a Core 2 can do "des ede3" at 0.39 gigabit/second, while http://www.xilinx.com/support/documentation/application_notes/xapp270.pdf says a xilinx spartan-ii can do 13.3Gb/s. Even if you can get 4x the throughput on 4 cores, that's still 10% as fast as the FPGA.
[18:11:09] <SWPadnos> it often boils down to transferring data into/out of the FPGA
[18:11:53] <jepler> (and that's a 2001 article, presumably you could go faster and/or put more des3 cores on one chip now; even then, nearly 2 cores fit on one chip)
[18:40:33] <chr0n1c> yo!
[18:42:05] <jmkasunich> yoyo
[18:42:23] <SWPadnos> oy!
[18:44:36] <chr0n1c> :) anyone making chips today?
[18:45:12] <SWPadnos> no, but I may eat some soon
[18:45:19] <chr0n1c> * chr0n1c went to work for 4 hours this morn... played with some brushed aluminum dash overlays for a camaro and then came home...
[18:46:30] <chr0n1c> the silly laser cutter people leave some burnt scuxzz around all the edges i gotta clean like 4000000 pcs with laquer thinner
[18:46:36] <chr0n1c> scuzz*
[18:46:51] <chr0n1c> laquer thinner and a paper towel
[18:47:10] <chr0n1c> uhh did i spell that wrong? geez
[18:48:35] <chr0n1c> i wish the spell checker would check, after all that's what it's supposed to do!
[19:00:25] <K`zan_emc> Argh, anyone know what CUPS is looking for for a login / password on the 6.06 EMC distro. Neigher root nor myself works :-( and of course no help from CUPS :-(
[19:01:39] <K`zan_emc> There is no user "CUPS" only: cupsys:x:100:106::/home/cupsys:/bin/false
[19:02:23] <K`zan_emc> argh....
[19:03:04] <SWPadnos> what are you trying to do with CUPS?
[19:03:32] <chr0n1c> all my printers just worked when i plug them in i never had to mess with cups
[19:03:42] <K`zan_emc> Network printer...
[19:04:00] <K`zan_emc> lp was not half the nightmare CUPS is...
[19:04:01] <chr0n1c> plug in the usb cable... wait a few seconds then print
[19:04:16] <K`zan_emc> Printer is plugged in on the server in the other room :)
[19:04:22] <chr0n1c> ohh if it's a windows printer you need to use the password and login from the windows box
[19:04:34] <K`zan_emc> linux server :-)
[19:04:44] <chr0n1c> well then use those passwords?
[19:05:38] <K`zan_emc> No go on that either. Did I miss saying I hate CUPS, a goddamn troll for support extortion :-(.
[19:06:01] <K`zan_emc> Piece of fecal matter...
[19:06:24] <chr0n1c> google "cups network print 6.06"
[19:06:31] <K`zan_emc> Enter your username and password or the root username and password to access this page
[19:06:39] <K`zan_emc> Neither worked. Sigh.
[19:07:05] <K`zan_emc> And *after* you go through all the setup...
[19:07:15] <K`zan_emc> cranial rectal inversion, sigh.
[19:07:22] <K`zan_emc> sneakernet time...
[19:07:41] <fenn> cups wants root password
[19:08:34] <chr0n1c> if there is no root password set with su passwd then you prpbably don't have a root password
[19:08:58] <chr0n1c> which.. would make cups not accept any attempts at using a password
[19:09:06] <chr0n1c> .. i think i'm right on that
[19:10:05] <K`zan_emc> I have a root password and can su - to it with no problem in a terminal, otherwise my personal works with most everything else.
[19:10:39] <chr0n1c> are root and your user account members of the printing group whatever it's called?
[19:10:54] <chr0n1c> on the print server box*
[19:12:07] <chr0n1c> .. don't listen to me i don't no junk about cups anyways
[19:12:17] <chr0n1c> ;)
[19:13:17] <chr0n1c> offtopic: i just found a "stop drug ads" petition, lol
[19:15:22] <tomp> what happens when you goto ? ( thats where you config you cups printer )
[19:15:47] <K`zan_emc> chr0n1c: I think so, usually are, but checking
[19:18:16] <K`zan_emc> yep, got lpadmin
[19:18:33] <K`zan_emc> easier to copy a 4k file to a CD and take it over :-)
[19:21:22] <chr0n1c> usbsticks!
[19:21:38] <fenn> jeez at least scp the file
[19:21:48] <chr0n1c> yeah ftp or something
[19:22:32] <chr0n1c> i email things to myself @ gmail when i don't have a usb flash drive handy
[19:57:16] <chr0n1c> 12 more sugar snap pea seeds just got planted in the J garden ;)
[19:57:45] <chr0n1c> i'm not sure on vegetable export laws but i'll share when they are done
[20:21:45] <alSMT> k`zan did you getradius comp working?
[21:29:08] <alSMT> K`zan read back I IRC you earlier ^^ or read the log bbl
