[00:21:55] <CIA-49> EMC: 03jepler 07TRUNK * 10emc2/src/hal/utils/halcmd_commands.c: fix segfault on 'halcmd show pin'
[00:22:33] <jepler> * jepler sings "there are no strings in C"
[00:22:36] <jepler> no arrays either
[02:11:07] <cradek> or memory management
[02:12:31] <cradek> ah, our old friend G92
[02:16:26] <cradek> jepler: your apport question has met resounding silence so far...
[02:16:40] <jepler> cradek: yeah I see that
[02:16:55] <jepler> I wonder if nobody's listening, or if I sounded like a dick
[02:17:55] <cradek> it seems completely reasonable to me (sitting here on your side of the fence, granted)
[02:18:18] <jepler> or if there are no good, quick answers
[02:18:34] <cradek> right
[02:30:48] <cradek> unfortunately "nobody really knows the answer" and "everyone is ignoring you because you're an idiot/dick" look exactly the same from the outside
[02:34:18] <skunkworks> what about - lots of people know the answer.. but they are the dicks.
[02:35:08] <cradek> in my opinion the chances of all the people working on a particular free software project being dicks is extremely remote
[02:35:26] <cradek> a few of them being dicks: somewhat possible
[02:35:52] <cradek> a few of them appearing to act like dicks sometimes: somewhat likely
[02:36:01] <cradek> I should stop here :-)
[02:38:52] <jmkasunich> don't stop know, you're on a roll
[02:39:09] <cradek> hello
[02:39:12] <jmkasunich> s/know/now
[02:39:14] <jmkasunich> hi
[02:40:30] <skunkworks> heh
[02:43:43] <jmkasunich> I wonder how hard it would be to make the g-code for fenn's twisty shape?
[02:44:01] <jmkasunich> probably brain twisting
[02:44:16] <cradek> you mean do the unfolding?
[02:44:25] <jmkasunich> no, to mill the shape out of the solid
[02:44:50] <cradek> hard
[02:44:56] <SWPadnos> my first thought when I saw the photo was "I'd like to see that in solidworks" :)
[02:45:09] <SWPadnos> I'd say neither is easy
[02:45:29] <fenn> it's a nurbs surface and/or mesh in blender
[02:45:41] <SWPadnos> especially if you account for the folds by cutting angled grooves
[02:46:12] <SWPadnos> there's no guarantee that a blender surface can be cut from a (single) flat piece
[02:47:37] <jmkasunich> http://www.math.binghamton.edu/alex/steel_plastic.html
[02:47:40] <jmkasunich> scroll down
[02:48:29] <fenn> mine's prettier :)
[02:49:57] <jmkasunich> http://en.wikipedia.org/wiki/Trefoil_knot
[02:50:45] <jmkasunich> I'm wondering if knowing the mathematical representation is a step toward writing the g-code (by writing a program to generate the g-code)
[12:38:23] <skunkworks_> logger_dev: bookmark
[12:38:23] <skunkworks_> Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emcdevel/2008-05-15.txt
[12:39:46] <rayh> beautiful mornin here skunkworks
[12:39:56] <skunkworks_> Yes - it is :)
[12:58:04] <skunkworks_> We are going to see npr - talk of the nation - science friday here in milwaukee tomorrow. Should be fun.
[13:35:57] <rayh> Neat
[18:02:40] <rayh_> nick rayh
[18:03:09] <alex_joni> * alex_joni lends rayh_ an "/"
[18:03:10] <rayh_> oops
[18:03:17] <rayh_> thanks
[18:04:57] <rayh_> rayh_ is now known as rayh
[18:08:53] <rayh> alex_joni, You must have updated stuff on the image. The md5 sum is different from the one I got last.
[18:09:20] <alex_joni> rayh: you got the -aj07 last time?
[18:11:21] <rayh> No I don't think so.
[18:11:51] <alex_joni> then yeah, I changed it a bit..
[18:11:53] <rayh> Nope just says desktop
[18:12:11] <alex_joni> but nothing you shouldn't already have installed (via updates)
[18:12:32] <rayh> I see that the download link is to 6.06 still on .org
[18:13:36] <alex_joni> yeah, changing it now .. but I'm pondering on the wording
[18:15:19] <rayh> I wonder if we want to have links to both 6.06 and 8.04 for a while.
[18:18:41] <alex_joni> that's what I'm doing
[18:21:39] <alex_joni> how does this look? http://www.linuxcnc.org/content/view/21/4/lang,en/
[18:27:01] <skunkworks_> Nice
[18:32:03] <jepler> looks OK to me too
[18:34:53] <rayh> Good.
[20:00:04] <jepler> alex_joni: mktemp -d should be perfectly safe for this purpose
[20:01:25] <alex_joni> jepler: I never tried any of the two.. but if you can test it.. feel free to change emc2-install.sh from ~/www../hardy/.
[20:02:12] <jepler> alex_joni: I'll wait for more reports of this key problem first
[20:02:25] <alex_joni> that was my thinking too..
[20:03:12] <jepler> besides every windows refugee knows just to click "OK" "Accept" "Continue" when told something about security
[20:03:46] <alex_joni> that is quite funny (actually sad & true)
[20:04:29] <SWPadnos> but you have to remember t ocheck the "don't ask me again" checkbox
[23:01:12] <jepler> the installing web page says: "Go to the Permissions tab and check the box for Owner: Execute." but on Hardy it's "Execute: [ ] Allow executing file as program".
[23:07:20] <jepler> new installation scripts (tested on my virtual machine): simple: emergent.unpy.net/files/sandbox/emc2-install-1.sh complex: emergent.unpy.net/files/sandbox/emc2-install.sh
[23:07:41] <jepler> "simple" reorganizes the way the script becomes root (by reinvoking itself) and gets rid of use of gnupg in favor of including the key inline
[23:08:10] <jepler> "complex" attempts to do more than it should, by checking the distribution name against supported ones, and using 'zenity' to show dialogs to the user
[23:15:31] <fenn> * fenn votes for simple
[23:16:30] <fenn> users will be doing one of two things: installing onto an already running linux system that presumably they know how to use and arent expecting totally weird installation interfaces, or install from live-cd
[23:17:59] <jepler> maybe I should save the "detect if it's the right OS version" part of the complex script, because I have a feeling (but don't know for sure) that people try to run the dapper installer on other systems, and who knows what it'll do
[23:18:23] <jepler> (probably apt will be unable to satisfy the requirements, but it would be nice to show a nice clear dialog to the user in this case instead)
[23:18:52] <jepler> but yeah I lean towards simple as well -- it'll be more robust
[23:18:56] <jepler> (for instance, I didn't check if kubuntu has zenity)
[23:20:06] <fenn> it's not installed by default
[23:20:30] <jepler> really?
[23:20:51] <fenn> well, its not there, and i didnt go on a gnome-deletion rampage
[23:21:03] <jepler> you mean on kubuntu then
[23:21:09] <fenn> yes
[23:21:26] <jepler> ok, well, strike that
[23:21:33] <jepler> zenity is off the table
[23:24:23] <jmkasunich> is it considered heresy to have them open a shell and run a script? then you don't need dialogs, you can just print messages
[23:24:51] <jmkasunich> * jmkasunich heads for the kitchen
[23:25:04] <jepler> jmkasunich: it's a well-proven fact that some people can't read monospaced text; even worse if it's white on a black background
