[02:53:38] <DanielFalck> SWPadnos: do you have a number where I can call you?
[02:54:00] <DanielFalck> about some contract work
[02:57:20] <SWPadnos> sure
[02:57:33] <DanielFalck> ddfalck2002@yahoo.com
[02:57:56] <SWPadnos> ok - it'll come from "Thoth Systems" - info in the signature line
[02:58:03] <DanielFalck> ok thanks
[02:58:20] <DanielFalck> are you headed out for the cnc fest tomorrow?
[02:58:28] <SWPadnos> yep
[02:58:44] <DanielFalck> we'll email you
[02:59:05] <SWPadnos> ok - I'll respond some night after driving ;)
[02:59:15] <DanielFalck> np
[02:59:33] <DanielFalck> next week sometime would be fine : )
[02:59:52] <DanielFalck> as if you'd have time then : )
[03:00:37] <SWPadnos> yeah
[03:19:29] <toastyde1th> okay i have a hypothetical situation
[03:19:35] <toastyde1th> let's say you're in calculus
[03:19:49] <toastyde1th> but signed up after barely squeeking through precalculus uh, three years ago
[03:20:14] <toastyde1th> and now find yourself having to teach yourself precalc as you go through differentiation
[03:20:18] <toastyde1th> what do you do, it's too late to drop.
[03:28:23] <jmkasunich> I'm so glad college was 20+ years ago
[03:29:07] <cradek> heh 10+
[03:30:04] <cradek> I don't know if there's a good answer to your hypothetical question other than "work hard" and maybe "learn from your mistakes"
[03:30:20] <fenn> watch youtube videos about math
[03:30:26] <cradek> many people porkup and retake a class once
[03:32:25] <toastyde1th> the real problem is there's a test every three classes, and the course is only 9 weeks
[03:32:29] <toastyde1th> roughly half a normal semester
[03:32:34] <toastyde1th> this was not the best idea i've ever had
[03:33:25] <cradek> does precalc mean trig?
[03:33:41] <skunkworks> I think I liked the thrill of going into tests without studying.. I was young and stupid then.
[03:33:59] <cradek> I don't recall much trig in calc 1 - lots in calc 2
[03:34:30] <toastyde1th> cradek: no
[03:34:51] <toastyde1th> precalc is like, the algebra that will really be used for calc later on
[03:35:20] <skunkworks> Plus it went well with my procrastination problem.
[03:35:21] <toastyde1th> a lot of factoring stuff
[03:35:23] <cradek> what kind of stuff are you having trouble with? maybe someone can suggest a book (or more likely, wikipedia)
[03:35:34] <toastyde1th> that's what i am also having trouble nailing down
[03:35:45] <toastyde1th> "what is this called that i am screwing up"
[03:36:22] <toastyde1th> a lot of it is dealing just with polynomials
[03:36:29] <toastyde1th> not simple ones, but complicated ones
[03:36:33] <toastyde1th> (for me, anyway)
[03:36:51] <toastyde1th> I'll divide something out when I wasn't actually able to do that at the moment
[03:38:23] <toastyde1th> like we are going into the laws of differentiation, like f'(x) * g'(x) = f'(x)g(x) + g'(x)f(x)
[03:38:49] <toastyde1th> and when f and g are things like (4x^3 + x^2 +9) and so forth
[03:39:26] <toastyde1th> i just never learned the manipulations as well as i should have, such that I can't always identify what's possible
[03:40:00] <cradek> ah, I see, the stuff where you have to have a feel, not just learn some identities or something
[03:40:34] <toastyde1th> yeah, i was very much sleeping in class the first time around
[03:40:46] <toastyde1th> and i'm picking it up fast, but the class is faster
[03:41:02] <cradek> is there a TA or can you visit the prof?
[03:41:08] <toastyde1th> unfortunately not
[03:41:23] <toastyde1th> unless the prof is still around at 8 pm on weekdays
[03:41:37] <fenn> wikipedia is really bad for math
[03:41:38] <toastyde1th> there's even a mathlab at school, but it closes at friggin' six
[03:42:16] <cradek> mathworld.wolfram.com is great
[03:42:40] <fenn> toastyde1th: you might also want to just play around with a symbolic math program like mathematica
[03:43:03] <toastyde1th> i've been using my ti-89 in class to dork around with what equals what
[03:43:07] <toastyde1th> i will look at mathematica now
[03:43:41] <cradek> it's my personal opinion that using a calculator like that makes it worse
[03:43:56] <toastyde1th> for what reasons
[03:43:58] <fenn> you may be right
[03:44:12] <toastyde1th> it tells me when i did it wrong and helps me figure out where
[03:44:12] <cradek> they are the worst of all possible worlds: symbolic math programs, calculators, general purpose computers
[03:44:12] <fenn> but it is my personal opinion that conventional math education stinks
[03:44:22] <toastyde1th> otherwise i'd have no feedback
[03:44:42] <toastyde1th> so i'm basically looking at either staring at the professor confused, or using what few resources i have
[03:44:48] <toastyde1th> =(
[03:45:12] <cradek> can you study with a friend or two in the class? that got me through a couple impossible ones.
[03:45:54] <toastyde1th> that is looking like a limited option at this point
[03:46:01] <toastyde1th> the few people i sit around are as confused as i am
[03:46:15] <cradek> fenn: probably true, probably unhelpful (like my advice too)
[03:46:30] <toastyde1th> my cousin just got into princeton for a masters in physics, but he's too far away to be of regular help
[03:46:38] <toastyde1th> 1 1/2 hrs away
[03:46:39] <cradek> toastyde1th: if everyone is lost, maybe the class is not being taught very well
[03:46:44] <toastyde1th> it's not, unfortunately
[03:46:56] <toastyde1th> he spends a LOT of time on stuff that isn't part of the curriculum
[03:47:05] <toastyde1th> "now this isn't necessary now, but you're going to see it in calc 2"
[03:47:23] <toastyde1th> then he spends an hour of a three hour class on something he won't be testing us on
[03:47:29] <Rugludallur_> toastydea1th: how about going through some of the online class material from berkeley or mit ?
[03:47:39] <cradek> man, 3 hour math class ...
[03:47:43] <toastyde1th> is it on their webpages?
[03:47:52] <Rugludallur_> toastydea1th: yup, both have all classes on websites
[03:47:56] <cradek> that just can't work very well
[03:48:10] <renesis> i dropped mine
[03:48:17] <toastyde1th> it's rough man
[03:48:23] <toastyde1th> but it's what i can do right now.
[03:48:51] <Rugludallur_> MIT also has a very nice class on metal fabrication (I probably should not have told you that ;)
[03:49:17] <toastyde1th> lol
[03:49:19] <cradek> to me, it sounds like you will make it
[03:49:36] <toastyde1th> i don't know, i really want to not just pass the class but be proficient in calculus
[03:49:40] <toastyde1th> and it is not looking likely
[03:49:49] <toastyde1th> 90 on the first test, but a 69 on the second
[03:49:57] <toastyde1th> and min passing grade is 75
[03:50:02] <cradek> proficiency in anything doesn't come just from classes :-)
[03:50:18] <toastyde1th> well i guess i mean get the fundamentals
[03:50:42] <toastyde1th> rather than pass the class and forget everything
[03:50:55] <cradek> proficiency in calculus to me means knowing what is possible, when it applies to a problem at hand, and what to look for in the book (or wolfram) to solve it
[03:52:02] <toastyde1th> heh
[03:52:09] <toastyde1th> the solving it part
[03:52:10] <cradek> for someone who uses it every day they wouldn't have to look up the quotient rule like I would, but who cares, I know it's there waiting for me
[03:53:07] <toastyde1th> i can get that
[03:53:20] <cradek> so you're passing - keep doing that and you'll be fine
[03:53:23] <toastyde1th> but like, i am screwing up bad on what appears to be remedial stuff
[03:53:33] <toastyde1th> i guess, i'll see what happens
[03:53:47] <cradek> do you have the book from the precalc class you slept through?
[03:54:09] <toastyde1th> nope
[03:54:11] <toastyde1th> i didn't buy it
[03:54:18] <toastyde1th> this was back in comp sci when i didn't care at all about school
[03:54:22] <toastyde1th> now i keep all my books
[03:54:49] <toastyde1th> also he uses proofs for everything
[03:54:59] <toastyde1th> and holy crap, what's a magic zero
[03:55:16] <ds2> interesting
[03:55:34] <toastyde1th> and how does he go from a simplified polynomial to distributing something unevenly across it
[03:55:45] <toastyde1th> i am just looking at the tricks he's using and i have no idea where they're coming from
[03:57:03] <toastyde1th> and it's not like he's going to stop and explain it
[03:57:07] <toastyde1th> because it's not calc
[03:57:13] <fenn> magic zero?
[03:57:18] <cradek> ?
[03:57:35] <toastyde1th> like, when he was proving f'(x) / g'(x)
[03:57:52] <toastyde1th> you have to add stuff that equals zero to it
[03:57:55] <toastyde1th> out of nowhere
[03:58:16] <fenn> well, x+0=x
[03:58:58] <toastyde1th> no not that
[03:59:06] <fenn> proofs are always like that, it's wy i hate them
[03:59:27] <toastyde1th> this was stuff like + f(x)g(x+h) - f(x)g(x+h)
[03:59:44] <toastyde1th> or something similar, i don't understand it much less remember it
[03:59:49] <toastyde1th> and he went too fast for me to copy it verbatim
[04:00:03] <cradek> is that the kind of stuff on your tests, or is he just explaining the quotient rule?
[04:00:11] <toastyde1th> i don't know!
[04:00:14] <toastyde1th> i have no clue.
[04:00:22] <toastyde1th> i don't know what he wants us to know and what he's just rambling on about
[04:00:32] <cradek> what was on your first two tests?
[04:00:41] <toastyde1th> first was a precalc review
[04:00:44] <toastyde1th> second was limits
[04:01:08] <cradek> if he's proving the quotient rule, he's either showing off or trying to give you a feel for why it works. I doubt he will expect you to also prove it later.
[04:01:19] <toastyde1th> he wants us to memorize the rule itself, but not the proof
[04:01:26] <toastyde1th> but he used up all the time explaining why it's right
[04:01:32] <toastyde1th> and was like "now why don't you go home and try it"
[04:01:47] <ds2> le hospital's stuff? (sp)
[04:01:50] <toastyde1th> i want to murder him
[04:02:08] <toastyde1th> why would someone prove something's right, and spend no time showing how to use it
[04:02:16] <toastyde1th> when what he wants us to know is how to use it
[04:02:36] <K`zan> Evening folks
[04:02:39] <cradek> that's where "left as an exercise for the student" comes from
[04:02:41] <toastyde1th> and then he throws curveballs, like he'll use that rule
[04:02:50] <toastyde1th> and is like "now let's try it"
[04:02:51] <K`zan> Anyone doing laser engraving?
[04:03:08] <toastyde1th> throws soemthing up, and then psychs everyone out by saying "aha! you shouldn't use that thing we just went over"
[04:03:20] <ds2> K`zan: trying to
[04:03:23] <toastyde1th> and then spends 20 minutes showing us some OTHER thing we don't practice
[04:03:25] <cradek> K`zan: I bet we'd all like to
[04:03:28] <toastyde1th> whatever, i will get through this
[04:03:29] <toastyde1th> thanks guys
[04:03:45] <K`zan> Dealextreme has some fairly powerful lasers, but google wasn't much help for homebrewing one.
[04:04:04] <ds2> DX's lasers are weak
[04:04:10] <K`zan> Not sure those would be suitable though.
[04:04:20] <K`zan> weak, 200mW is weak>
[04:04:24] <K`zan> ?
[04:04:30] <ds2> they are fine if all you want to do is make marks slowly on black absorbing material
[04:04:41] <K`zan> ah, understand.
[04:04:44] <ds2> yes, 200mW barely touches black electrical tape and it takes a while
[04:05:07] <ds2> 5-10W is more useful
[04:05:10] <K`zan> Would like to find something to chuck in the Z axis to do it, $10K+++ not likely for me.
[04:05:27] <K`zan> Where can one get lasers of that level reasonable?!?
[04:05:31] <ds2> reprap head is what I am thinking of
[04:05:37] <ds2> laser specialists... $$$$$$$$$$$$
[04:05:44] <K`zan> Sigh....
[04:06:26] <K`zan> http://www.precisionlaserspecialist.com/
[04:06:40] <K`zan> errr, nope
[04:07:21] <ds2> most engraves are CO2 lasers
[04:09:20] <K`zan> Sounds like it is going to be too expensive for my buget. Suspect the laser and PS are going to be reasonably expensive.
[04:09:25] <ds2> heh...one of my freshman prof is on PBS
[04:09:35] <K`zan> My condolences :).
[04:09:53] <K`zan> Oh well. Next! :-).
[04:10:27] <ds2> One thing that might be possible with the DX laser (haven't confirmed) is to break open the 100mW green laser
[04:10:38] <K`zan> Back to hacking at the gcode...
[04:10:42] <ds2> and take the IR driver diode out....that might be up to 1W
[04:11:04] <K`zan> Hummm, food for thought there, lemme see what those go for,
[04:11:21] <ds2> about $100, IIRC
[04:11:36] <ds2> but I donno how easy it is to break off the KTP xtal from the driver diode
[04:12:28] <K`zan> 200mW isn't that muck more expensive - $95 vs $120.
[04:12:56] <K`zan> Yeah, that would be a lot of change to toss on a gamble that it might just possibly maybe just work though.
[04:12:56] <ds2> from what I read, the 200mW are the same (Cherry picked) so the driver diode might not be stronger
[04:12:57] <K`zan> :-)
[04:13:36] <fenn> something i was just looking at r cheap laser diodes: http://superkuh.ath.cx/#018
[04:13:39] <K`zan> Wonder if I take that pile of keychain ones and point them all at the same place :-) LOL.
[04:14:09] <ds2> K`zan: that works but there is a very expensive combiner you need ;)
[04:14:40] <chr0n1c> i just found a hpgl importer c-hook for mastercam 9, woohoo!
[04:14:57] <chr0n1c> *it should be installed by default
[04:15:53] <chr0n1c> lol, i had to stop by to tell everyone.. should i add info to the wiki cam page?
[04:16:24] <K`zan> Would seem to be quite the thing to do :-)
[04:16:41] <ds2> are you also buy everyone Mastercam 9 licenses too? :)
[04:17:06] <K`zan> ds2 yes, any savings on the cheap(!!!!) laser pointers would probably be lost in the combiner :).
[04:17:18] <chr0n1c> uh, when i become a billionaire machine shop owner i will ;)
[04:17:23] <K`zan> Anyone familiar with the GO2 statement?
[04:17:40] <K`zan> Not really clear what the I and J parameters are supposed to be...
[04:17:43] <ds2> K`zan: you might have a better chance of doing it with the 200-300mW DVD diodes instead of the <5mW Keychain lasers
[04:17:59] <ds2> I/J are the relative coordinates to locate the center of the arc
[04:18:14] <ds2> relative as in the "origin" of that system is the point where you are at right now
[04:18:18] <K`zan> I can probably get those for $20 with junk transport stuff to toss :).
[04:18:34] <fenn> if the dvd players sell for $20 you must be able to buy them for much less separately
[04:18:50] <ds2> in buy they are less then $5 each
[04:18:51] <K`zan> Probably so if I could order them in 10K lots.
[04:19:10] <K`zan> buy.com - just the diode?
[04:19:20] <ds2> s/buy/bulk/
[04:19:22] <ds2> <--- eatting
[04:19:40] <K`zan> G2 x0.752 y0.000 I-0.752 J0.000 (and cut the circle)
[04:20:22] <K`zan> * K`zan stuffed from home brew enchelatas(sp?) make in burrito size tortillas :).
[04:20:32] <K`zan> Burp. Snore.
[04:20:37] <K`zan> Siesta!
[04:20:55] <chr0n1c> what i wouldn't give for an authentic burrito right now
[04:21:27] <K`zan> Heh, what does that mean :). MANY definitions for that including w/the touristas :).
[04:21:40] <K`zan> I'll stick to mine :).
[04:22:08] <chr0n1c> uhh it probably din't mean what your dirty mind thought it did... ;)
[04:22:20] <K`zan> Gotta get some coffee or siesta it will be.
[04:22:34] <K`zan> My mind is NOT dirty, I change it early and often!
[04:22:43] <K`zan> :-)
[04:22:45] <K`zan> COFFEE!
[04:22:47] <ds2> in that G2 statement, it means the arc's center is directly to the left of the current point, -0.752 away
[04:22:54] <chr0n1c> mt dew!! i drank some coffee at work this morning and i felt like i should be running laps, i usually just do the dew
[04:23:22] <K`zan> I worry that I may be caffine saturated :(.
[04:24:07] <chr0n1c> i always drink coffee really fast because it tastes so good with cream n sugar, i think that's why i get wired on it
[04:24:12] <K`zan> ds2: Thanks, not sure that makes sense to me yet. (NEMA23 motor boss hole).
[04:24:19] <chr0n1c> **possibly too much sugar as well, lol
[04:24:40] <chr0n1c> hey don't be talking about my boss hole when i'm not around ;)
[04:24:49] <K`zan> I drink mine black since I started roasting and grinding my own - doesn't need anything, but that sugar might help at this point.
[04:24:55] <K`zan> LOL
[04:25:06] <K`zan> brb
[04:25:30] <K`zan> ds2 it does make a circle, not an arc.
[04:26:15] <chr0n1c> :( hmm i just tried two hpgl files with the readhpgl chook and i got a blank screen when it was done... wtf??
[04:26:36] <chr0n1c> it was doing stuff... the little cursor was spinning and the hd light was going nuts
[04:27:05] <ds2> K`zan: circles are ARC's as far as G code is concerned
[04:27:09] <chr0n1c> anyone else got mcam9 wanna try it out?
[04:28:04] <ds2> K`zan: think about what do you need to describe a circle (or an ARC; ARC == segment of a circle)
[04:28:51] <chr0n1c> you can define stop and start points, i don't remember how at this point in time though
[04:29:03] <chr0n1c> *ds2
[04:29:14] <ds2> start point is always your current position
[04:29:23] <ds2> but just having an end point doesn't tell you enough info
[04:29:38] <ds2> you need to know the radius OR the center location of the circle
[04:30:02] <chr0n1c> i got to reliant on cam software.. my g-code is rusty rusty
[04:30:17] <chr0n1c> i always have to look up codes when i edit the cam files.. :(
[04:30:33] <ds2> that's what that G code line says - G02 <--- go CCW to form the arc/circle
[04:30:40] <ds2> X/Y defines the end point
[04:30:56] <ds2> I/J locates the center of the arc/circle relative to the current (starting) point
[04:31:18] <ds2> if X/Y == current position, you have a circle, otherwise it is an ARC
[04:31:48] <ds2> the other way of doing this is to use the R notation and define the Radius
[04:32:15] <ds2> but the R notation/method limits you to 180deg arcs so you need 2 call outs to form a circle
[04:34:36] <chr0n1c> interesting
[04:35:29] <toastyde1th> indeed
[04:35:48] <toastyde1th> toastyde1th is now known as toastydeath
[04:36:02] <toastydeath> g2 i-1.0 is way faster and less error prone
[04:37:08] <ds2> r notation is less math for hand coding
[04:37:29] <toastydeath> indeed, but i've never liked programming without a sketch of critical points in front of me
[04:37:30] <chr0n1c> how i would do it... create, arc, center point and radius, tolpath, contour, verify, post (who needs a text editor?)
[04:38:27] <ds2> you can't do a sketch if you have to visualize it in the generic case to write a G-code generator program
[04:39:12] <toastydeath> i didn't know we were talking about a generator program, sry
[04:39:16] <toastydeath> just came in.
[04:39:46] <toastydeath> just thought it was generic at tool programming
[04:39:58] <chr0n1c> can i run the real emc2 as a simulation on my non-RT kernel with sound?
[04:40:08] <chr0n1c> it crashed when i tried to start the sim
[04:40:38] <chr0n1c> i don't wanna do motion control, just run through the programs...
[04:41:06] <chr0n1c> then reboot into the RT kernel to run them.. the reason why is that qemu runs better on my stock kernel
[04:41:34] <chr0n1c> with which i can make use of some nice windoze cam/cad programs
[04:42:26] <ds2> toastydeath: we are talking about generic programming
[04:42:44] <ds2> I just sometimes prefer to write a code generator for repeated code then to hand write the same things over and over
[04:43:35] <Zaarq> ds2: lisp macros
[05:02:18] <ds2> no thanks, I'll generate them with perl :P
[05:04:51] <Zaarq> what about the unsung hero of code generators: emacs macros?
[05:06:08] <Zaarq> * Zaarq wanders off to check CPAN for gcode.pm...
[05:07:33] <chr0n1c> * chr0n1c wonders why an scg from hp2xx just crashed inkscape with no traces of error messages
[05:07:39] <chr0n1c> .svg*
[05:08:24] <Zaarq> heh. there is one. "Perl extension for cutting cycloidal gear wheels and related items out of sheet metal".
[05:10:08] <K`zan> ds2: OK, I can see that, so I= the first half of the circle and J= the return to start?
[05:10:25] <K`zan> Back, btw and a bit more awake now :).
[05:14:04] <ds2> K`zan: no
[05:14:15] <ds2> I/J is X & Y but relative to the current location
[05:14:52] <ds2> so (assuming G90/G51) - X0.000 Y0.000 is the current origin regardless of where you are it will go there
[05:16:29] <ds2> I1.000 J1.000 is a point 1*sqrt(2) distance, at a place 1.00 up and 1.00 to the right of where you are currently
[05:24:04] <chr0n1c> ohh i got my blank copper clad boards today, my first pc board i'll be milling is a function generator based on an xr2206 chip. pictures coming soon!
[06:15:23] <K`zan> ds2: Thanks, will pester you more on the morrow, I'l beat and heading for bed before I go face down in the keyboard :-)
[06:15:26] <K`zan> Night all

[10:17:09] <BiSiKLeT> Hi
[10:17:24] <BiSiKLeT> when i use emc with plasma cutter
[10:17:38] <BiSiKLeT> emc can do nesting to multiply parts ?
[10:18:54] <awallin> there are a few work offset coordinates, maybe 10?
[10:19:17] <awallin> then there are loops in g-code if you want to repeat the same program in slightly different places lots of times
[10:20:06] <BiSiKLeT> did u ever used nesting software ?
[10:20:54] <awallin> you mean a CAD tool which positions different parts for maximum efficiency? no I haven't used something like that, and emc doesn't have it
[10:21:00] <BiSiKLeT> yes
[10:21:08] <BiSiKLeT> thanx :(
[10:21:36] <awallin> that's more of a CAD/CAM issue, at lest with the traditional CAD-CAM-CNC workflow
[10:22:23] <BiSiKLeT> i see
[10:23:18] <awallin> I would think the nesting problem is something that's studiet at almost every cs department that does computational geometry. there should be open-source code out there for solving the nesting problem
[10:23:23] <awallin> studied
[10:23:54] <Vq^> what kind of algorithms are usually used for that kind of thing?
[10:24:32] <Vq^> ant-colony optimization?
[10:43:00] <micges> why I cannot add function to traj-thread ?
[10:50:42] <micges> ignore above
[11:43:09] <awallin> Vq: yep, I think the nesting problem can be expressed as a general optimization problem, so genetic algorithms, simulated annealing, and ant-colony may all be used
[13:40:46] <gezr> ants are slow though, they move all the numbers one at a time, need bee hive algo, that way, all the numbers hatch out at the same time.
[14:07:56] <skunkworks> anyone seen this? http://video.google.com/videoplay?docid=860235830940925547
[14:10:35] <skunkworks> http://video.google.com/videoplay?docid=3940699428479771797&q=source:015422501009045079122&hl=en
[14:10:46] <skunkworks> wth? demaganetizing something?
[14:11:36] <alex_joni> skunkworks: that's one of acemi's
[14:12:29] <skunkworks> I was wondering.. I saw the wire forming and parallel arm machine.
[14:13:24] <alex_joni> hmm.. haven't seen the second video
[14:13:50] <alex_joni> looks like metal treatment.. first heating, then rapid cooling
[14:13:58] <skunkworks> ah - makes sense
[14:14:03] <alex_joni> increases strength
[14:15:10] <alex_joni> looks like inductive heating
[14:15:15] <jmkasunich> hmm, thats weird - my phone line (voice) is dead, but the DSL still works
[14:16:42] <cradek> oh well, that's not good for much anyway
[14:16:56] <jmkasunich> uh, I beg to differ
[14:17:53] <jmkasunich> I'm one of those holdouts that doesn't have a cellphone surgically attached to me
[14:18:29] <cradek> sometimes I think all consequential communication is by email - phones are just for telemarketers
[14:18:36] <skunkworks> * skunkworks only started that 2 years ago...
[14:19:12] <jmkasunich> well, I want to call the vet so I can take the slathering beast in to get his nails trimmed
[14:21:12] <alex_joni> jmkasunich: http://www.easternmarble.com/images/107/typeclasses/products/135802_full.jpg
[14:22:27] <jmkasunich> lol
[14:22:49] <jmkasunich> yipe! run away run away
[14:24:41] <skunkworks> I was thinking it was a job for emc...
[14:32:44] <cradek> haha, on homeshopmachinist.net: how do I hold all three wires and a mic while measuring threads on the lath?
[14:32:52] <cradek> answer: "I use duct tape"
[14:33:23] <cradek> "I slather grease on everything so it sticks together"
[14:33:58] <cradek> am I the only one who thinks this isn't very hard to do...?
[14:34:09] <alex_joni> what's a mic?
[14:34:13] <cradek> micrometer
[14:34:24] <cradek> err lathe
[14:34:25] <jmkasunich> 4 or 5 pieces, 2 hands
[14:34:36] <jmkasunich> 4 if the part is in the chuck
[14:34:54] <cradek> oops, I better be quiet or I'll have to give away my technique at workshop
[14:35:38] <alex_joni> cradek: you need to write a leaflet and sell it at the workshop
[14:35:48] <cradek> demos: $10 each
[14:38:35] <alex_joni> limited to 1 person/demo
[14:40:33] <skunkworks> an a signature on a non-disclosure contract
[14:40:57] <skunkworks> (and a yearly support fee)
[14:42:27] <cradek> good idea!
[14:52:17] <jmkasunich> fsckers
[14:53:07] <jmkasunich> damn automation - I think all the human phone operators in the world must now work for telemarketers
[14:53:27] <jmkasunich> heaven forbid that a customer who is already buying a service be allowed to talk to a human
[14:55:36] <steves_logging> steves_logging is now known as steve_stallings
[14:56:03] <cradek> hi steve
[14:56:21] <cradek> are you and matt starting your drive today?
[14:56:53] <jmkasunich> to add insult to injury, I forgot to refill the pay-as-you-go cellphone, and the $70 or so that was left in it expired within the last week or two
[14:57:03] <cradek> arg
[15:00:51] <jmkasunich> "we'll have your trouble fixed by sunday night"
[15:01:06] <jmkasunich> considering that the trouble is almost certainly in the central office, that is pretty lame

[17:24:29] <archivist> cradek, my mic has hooks to hang the wires from
[18:54:27] <cradek> yuck, I80 is closed for a few hundred miles between us and galesburg
[18:58:51] <jmkasunich> cradek: yuck
[18:58:54] <jmkasunich> what is the alternative?
[18:59:22] <jmkasunich> why is it closed? construction usually doesn't close it, just delays things
[19:00:00] <alex_joni> http://www.dot.ca.gov/hq/roadinfo/i80
[19:00:24] <cradek> it's underwater
[19:00:29] <cradek> the whole state is
[19:01:04] <jmkasunich> iowa or ne?
[19:01:08] <cradek> iowa
[19:01:51] <jmkasunich> you guys need some slope
[19:02:15] <cradek> well NE has it - it slopes toward IA
[19:02:20] <ds2> time to fabricate a snorkel for your car ;)
